As we welcome in the New Year, we want to take the time to bid farewell to Prof. Celia Holland who retired in October 2022 from the Zoology Department. I believe I speak for everyone in Zoology and Trinity who’ve had the great pleasure of meeting Celia, that she will be a huge loss to the department. She has acted as Head of School, Head of Discipline, Director of Research, and Chair of the School of Natural Sciences Athena Swan Self-Assessment Team to name a few.
Celia on fieldwork collecting specimens
Celia started her teaching journey in the Zoology Department in 1985, following an exuberating Post-Doc in Panama, where her passion for the epidemiology of globally significant but neglected helminths, such as Ascaris, developed. Although she was one of the “new kids on the block” and one of very few females in a male dominated department, she was quick to make her mark and let the world know her presence. Celia was quick to fix the muddled teaching schedule, by rightly advocating for herself to be lecturer of parasitology and pre-med, which was previously taught by a limnologist. Not only did this strengthen the parasitology course, it was also the start of a long and fruitful relationship with the medical department in TCD, starting Celia’s so called “double life”. Her work on an astonishing diversity of parasites and their hosts crossing multiple disciplines, has improved human health and increased our understanding of parasites and their effects.
Anyone who has had the great pleasure to interact or work with Celia will know her as a calm, reassuring presence. Her delightful demeanor and passion could draw you into the world of parasites, making you question whether you should continue to eat pork or spaghetti, while simultaneously spurring up a profound desire to delve deeper into parasitology, converting (or even infecting) many students. This impact, her vast knowledge and expertise, along with her belief that “you are only as good as your last lecture”, unsurprisingly granted Celia with a Lifetime Achievement Award at the Provost’s Teaching Award 2018 – 2019.

Celia has not only had a huge impact on the college community and the people she met, but has also significantly impacted the global community with her research, which took place around the globe. Celia has worked on a multitude of parasites and their hosts over the years. She has studied parasites affecting Irish school children, raising awareness of the symptoms and impacts of toxocaral eye disease, a treatable and preventable disease caused by Toxocara. Toxocariasis, a zoonotic infection, has huge impacts on human health around the globe. She also highlighted the importance of targeting Trichuris trichiura, a whipworm that can infect over 90% of children in the tropics and subtropics, causing major impacts on health and quality of life. Celia demonstrated the importance of treating children and girls in particular, as adolescent girls have higher iron requirements due to menstruation, pregnancy & breast feeding. Most notably, Celia worked on one of the most prevalent and simultaneously under-researched Neglected Tropical Diseases Ascaris, a helminth parasite of humans and animals. She worked on both Ascaris lumbricoides (human parasite) and Ascaris suum (pig parasite). Ascaris lumbricoides has been described as the ultimate Neglected Tropical Disease, both because of its impact on child health and the general lack of awareness around it. This work culminated when Celia published “Ascaris: the neglected parasite” in 2014. The book “provides a blueprint of how a single parasite can stimulate interest in basic biology, clinical science, veterinary science, public health and epidemiology”. Her dedication to understanding and investigating parasites and their impacts, has led to her being an Invited Expert on the WHO Advisory Panel on Parasitic Diseases and a member of the WHO Guideline Development Group (GDG) – deworming, in 2016, a Member of the WHO Foodborne Disease Burden Epidemiology Expert Elicitation in 2014 and an Editor of the Cambridge Journal Parasitology 2011-2019. Celia has a remarkable repertoire of awards, recognitions and representations, befitting a woman of her caliber and dedication.
There are very few retiring researchers who get a glowing endorsement of their contribution to this world from a Nobel Laureate, however, Celia is no ordinary person. Professor William C. Campbell writes:
“I write to congratulate you and to wish you all the best on your retirement. You have had an outstanding career. Your classroom listeners, your research students, your academic colleagues and your research collaborators have benefited enormously from your knowledge of zoology, and especially from your expertise and insights in the field of parasitology. Indeed the broader field of epidemiology has benefited from your pioneering field-work… Countless students and other readers of your papers and books have similarly been beneficiaries. Your ability to assess, extract and organize mountains of facts, and to synthesize coherent conclusions, has been extraordinary. (When you were in AmericaI I was fortunate to hear one of your lectures on ascariasis.) Your magnificent contribution to science will endure. Again, congratulations — and best wishes for a rewarding and happy retirement.”
Celia with Prof. William C. Campbell
Once again, we would like to wish Celia all the very best in her retirement as she travels the world, sharing her light to everyone fortunate enough to meet her. I also want to thank all her colleagues and friends for their wonderful stories during Celia’s retirement party and contributions to this post.
As the semester flies by, the EcoEvo annual Photo Competition draws ever closer!
The 2022/2023 showcasing will be the sixth instalment in the series and if previous years are anything to go by, the judges will have an extremely tough time choosing a winner. Year on year, the bar seems to have risen ever higher so we’re excited to see what you have in store for us!
For those of you in the dark, the EcoEvo Photo Competition is one of the most highly anticipated events of the year for Botany and Zoology, with the winner receiving prestige and respect from the Trinity Natural Sciences cohort. If that isn’t enough for you, the photo that claims first prize also gets to be shown off for year, becoming the new cover photo for the EcoEvo Blog and profile image on all social media pages. This competition gives us all a chance to present the amazing and strange snippets of our research that often miss out on the opportunity to be shared, so send us on whatever you’ve got!
Katrin Schertenleib captured a beautiful moment between two adult Puffins (Fratercula arctic) off the coast of Wexford on the Great Saltee island last year. Currently the poster image for the EcoEvo blog, is it soon to be succeeded by the 2022/23 winner! Clickhere to see the other entries from last year’s Photo Competition

We wish you all the best of luck in the sixth annual EcoEvo Photo Competition!
Our understanding of how species interact and evolve depends on accurate knowledge of the species that exist on Earth. There are still many species to be identified, however, even in evolutionarily significant regions such as Wallacea in central Indonesia, site of Alfred Russel Wallace’s pioneering work. Our new paper, completed jointly with researchers from Universitas Halu Oleo and just published in the Zoological Journal of the Linnean Society, draws on work carried out in Wallacea to identify multiple unrecognised species in the beautiful sunbird family. Made using modern genetic, acoustic, and statistical techniques, these discoveries add to our understanding of how life evolved in this region and reinforce some of Wallace’s original ideas.
The key discovery is the “Wakatobi Sunbird Cinnyris infrenatus”, a species endemic to the small islands of the Wakatobi archipelago, off Southeast Sulawesi in central Indonesia. The Wakatobi Islands have been separated from other landmasses since they first rose out of the sea, and so there has been plenty of time for their populations to evolve in isolation and produce endemic taxa, found nowhere else on Earth. The Wakatobi Islands have been recognised as a Key Biodiversity Area for their importance to the survival of biodiversity. The Wakatobi Sunbird is the latest endemic species to be identified by our research group, following previous work on the Wakatobi Flowerpecker and the double discovery of the Wakatobi White-eye and Wangi-wangi White-eye. It’s important that we know all of the species of Southeast Sulawesi and the Wakatobi Islands, because this region acts as a “natural laboratory” for the study of evolutionary processes such as cryptic sexual dimorphism, the “supertramp strategy”, and the links between behaviour and population divergence. The Wakatobi Sunbird is currently treated as a subspecies of the widespread Olive-backed Sunbird (Cinnyris jugularis), but our findings indicate that the Olive-backed Sunbird is actually made up of at least 4 reproductively isolated species.
Male Olive-backed Sunbirds from Sulawesi and nearby islands. Our new paper supports splitting this population as the “Sahul Sunbird (Cinnyris clementiae)”.
Male Wakatobi Sunbirds. This population is currently viewed as a subspecies of the Olive-backed Sunbird, but the genetic divergence we have found, along with its darker plumage, shorter wings, and different calls, support its recognition as a new species.
Female Olive-backed Sunbirds (“Sahul Sunbirds”) from Sulawesi and nearby islands. Sunbirds are sexually dimorphic, with the feales usually showing simpler plumage than the males.
Female Wakatobi Sunbirds. The analysis of plumage in our study used male birds, following previous taxonomic work on subirds.
The sunbirds (Nectariniidae) fill a similar niche in Africa, Asia, and Australia to the hummingbirds of the Americas. They are small birds with long bills that help them extract nectar from flowers. Like the hummingbirds, many sunbirds (males particularly) exhibit brightly coloured plumage, with beautiful iridescent or “metallic” feathers that reflect the sunlight. In fact, the naturalist William Jardine tells us in his 1843 volume on the sunbirds that sunbirds get their name “from their brightly-tinted dress, appearing in higher splendour when played on by the sun-beams”. For hundreds of years, ornithologists have used the patterns and colours of these feathers to identify sunbird species. Now, however, we can combine multiple forms of data to uncover patterns that weren’t clear from plumage alone. Our paper also looked at the Black Sunbird (Leptocoma aspasia), a species with male plumage that’s hard to examine because it mostly looks jet-black, except when the sun hits it in the right way to reveal other colours. We found a genetic split in this species that had not been suggested by any previous work, probably due to its plumage being less informative.

Finding species like these isn’t just interesting for its own sake. It is also our best evidence to understand how evolution produces new species. This is particularly interesting in a region like Wallacea, which played such a significant role in the development of evolutionary biology. The observations that Wallace made around this region led him to discover evolution by natural selection, work which was published jointly with Charles Darwin in 1858 in the same journal where our sunbird paper has just appeared.
One of the observations that inspired Wallace’s evolutionary thinking was the importance of biogeographic barriers. Wallace noticed that the animals found on Sulawesi are markedly different from those on neighbouring Borneo, evidence that species would evolve on one island and then have difficulty crossing over. This boundary came to be known as Wallace’s Line. We now understand that it represents the beginning of the deep waters of the Wallacea region, which persisted even when sea levels were lower, unlike the shallower waters of the adjoining Sunda Shelf which gave rise to land bridges. A similar barrier to the east came to be known as Lydekker’s Line. As seen in the map below, the range of the Olive-backed Sunbird (in yellow) is currently thought to cross both Wallace’s Line and Lydekker’s Line, while the Black Sunbird (in purple) stops at Wallace’s Line but crosses Lydekker’s Line. It’s quite remarkable to imagine these dainty little birds maintaining gene flow across barriers which block so many other organisms! Our work, however, has indicated that the Olive-backed Sunbird populations on either side of Wallace’s Line actually represent separate species. The same is true of Black Sunbird populations divided by Lydekker’s Line. Modern evidence has actually reinforced Wallace’s original ideas, showing once again that these Lines represent significant biogeographic barriers that block gene flow in most animals.
Map showing populations sampled for our new paper. We found evidence that the Olive-backed Sunbird is actually composed of separate species in the Philippines (“Garden Sunbird”). the Sunda Shelf (“Ornate Sunbird”), the Wakatobi Islands (“Wakatobi Sunbird”), and the islands from Sulawesi to the Sahul Shelf (“Sahul Sunbird”). We also found that Black Sunbirds in New Guinea are strongly genetically divergent from those in Sulawesi. These findings reinforce the importance of biogeographic barriers like Wallace’s Line and Lydekker’s Line to evolution.
Both evolutionary biologists and ecologists are gaining new insights from large datasets on the traits and genomics of species. However, as these datasets are organised by species, they rely on our species lists being accurate in the first place. Data from “species” like the Olive-backed Sunbird or Black Sunbird might prove misleading, as each of these actually represent multiple species. Meanwhile, a small population like that of the Wakatobi Sunbird may not be included in such a dataset at all if it isn’t recognised as a species.
To quote an 1863 paper by Wallace, the world’s species represent “the individual letters which go to make up one of the volumes of our earth’s history and, as a few lost letters may make a sentence unintelligible, so the extinction of the numerous forms of life which the progress of cultivation invariably entails will necessarily render obscure this invaluable record of the past”. It is therefore an irrevocable loss to the world, to humanity, and to science when a species goes extinct while still unrecognised, “uncared for and unknown”.
Hoga, one of the Wakatobi Islands where sunbirds were sampled for this study. It has been a privilege to see such beautiful places and animals for this research.
While the Wakatobi Islands are biogeographically “remote” due to their small size and the permanent water barriers that surround them, it is worth noting that they are not the stereotypical “desert islands” Western readers may imagine. The islands have been part of important shipping lanes since at least the 14th century, and the people of the Wakatobi are known for their maritime traditions and unique language. As Dr David Kelly, the second author on the recent paper remarked: “The identification of the Wakatobi Sunbird serves to remind us that biodiversity is everywhere. This bird wasn’t found in a remote rainforest, but along the scrubby margins of busy towns and villages. Let us hope the children of the Wakatobi will be able to enjoy these special birds for generations to come.”
A relief from Borobudur Temple on Java, built over 1000 years ago. The birds in the yellow boxes were identified as Olive-backed Sunbirds by Ashari et al. (2021). Their fascinating paper is available at https://li01.tci-thaijo.org/index.php/tnh/article/view/253401
The beauty of the sunbirds has attracted scientists and artists for many years. Elsewhere in Indonesia, Java’s Borobudur (the largest Buddhist temple in the world, constructed in the 8th or 9th century CE) displays carvings of Olive-backed Sunbirds drinking nectar on its walls. The researchers who identified these carvings hypothesise that this symbolises the Buddhist ideal of enlightenment. Over a thousand years later, sunbirds are still enlightening us on the origin of species.

Our new paper has found that the Olive-backed Sunbird is actually made up of at least four separate species.
We can’t thank our editors from the 2021/2022 year enough for their fantastic contribution to the EcoEvo Blog – Lucy Harding, Grace McNicholas and Richa Marwaha. We wish them all the best of luck in their research and hope to hear from them again soon!
The team produced a series of excellent blog posts, including an insight into the evolutionary divergence of Wallacea’s monarch flycatchers, restoration of biodiversity in Irish farmlands and a plethora of scientific podcasts that can be enjoyed by all. While we say goodbye to these three fabulous editors, we would also like to take the time to bid farewell to Prof. Celia Holland who retired this year from the Zoology Department. I believe I speak for everyone in Zoology and Trinity who’ve had the great pleasure of meeting Celia, that she will be a huge loss to the department. She has acted as Head of School, Head of Discipline, Director of Research, Chair of the School of Natural Sciences Athena Swan Self-Assessment Team and received the Provost’s Teaching Award for LIfetime Achievement in 2019. Celia has not only had a huge impact on the college community and the people she met, but has also significantly impacted the global community with her research on the parasitic worm ascaris – one of the major Neglected Tropical Diseases – which infects over a million people world-wide. Her dedication to understanding and investigating this disease has led to her being elected to Membership of the Royal Irish Academy and Fellowship of Trinity, an Invited Expert on the WHO Advisory Panel on Parasitic Diseases and a member of the WHO Guideline Development Group. We would like to wish Celia all the very best in her retirement as she travels the world, sharing her light to everyone fortunate enough to meet her.
We once again give Lucy, Grace and Richa our best and without further ado, let us introduce ourselves as the editorial team for the 2022/2023 year – Luke Quill and Aedín Mc Adams. We’re both thrilled to be a part of this project and are looking forward to bringing you new and exciting content each month from students and researchers alike. So, let’s get started on the introductions!
Luke
Hi everyone, my name is Luke (he/him). I recently started a PhD here in the Botany Department in TCD. A few of you may recognise me as I haven’t ventured too far from this place, having completed my undergrad in Botany last year! My main research interests are fungi and sustainable agriculture. I’m currently working with Professor Carla Harper on the use of mycorrhizal fungi and their associated plants to recover and recycle nutrient runoff from farms. This project is part of the NuReCycle Program which aims to protect the water quality of our vulnerable waterways here in Ireland.
As you might guess, I love hiking and foraging for all kinds of mushrooms so if you’re ever thinking of going for a stroll in the Dublin or Wicklow mountains give me a shout!
Aedín
Hello everyone, my name is Aedín (she/her). I am a first year research masters student in the Buckley Lab. I am currently investigating the efficacy of irrigation on the restoration of fen habitats for the reintroduction of the rare Geyer’s whorl snail Vertigo geyeri. This project is the first IROPI (Imperative Reasons of Overriding Public Interest) project approved in Ireland granted under the Habitats Directive. I completed my undergraduate here in the Zoology Department after first completing a year on the Trinity Access Foundation Course. My passions, which not only lie in conservation and nature, but also in access to education, lead me to volunteering in the mountains of Mexico for 3 months on an ethnobiological farm, rehabilitating the land, an opossum and building upon relationships with the community. I love to experience and learn new things, so I’m very excited to develop my blogging skills and learning about your ideas and research further!
Updates:
Along with the new editors, the EcoEvo blog is in need of a fresh makeover. Do you know what this means?….
The annual EcoEvo photo competition is back!! Some of you may know what this entails, but to our new readers, this is a time for you to show off your photography skills. The photo competition is where you can submit a photo you’ve taken, which will then be voted upon by our readers and will replace the current image on our banner and social media. More information and details will be in our November post, so keep your eyes peeled.
Until then, keep your cameras at the ready, and as always, keep an eye out for each other. With the days getting shorter and darker, we need to remind ourselves to be kind to ourselves and to reach out for support should we need it.
If you have any questions or ideas about a blog, please feel free to get onto us via Twitter, Instagram, Facebook or email (ecoevoblog@gmail.com).

General Science
This one is pretty self-explanatory! If you want to widen your knowledge of science to new topics, whether to argue with your uncle at Christmas dinner or to ace those pub quizzes you go to every week with your mates, these podcasts are for you!
Stuff you should know is a podcast which educates listeners on a wide variety of topics, often using popular culture as a reference, giving the podcast comedic value. It covers scientific topics from supernovae to rewilding but also history, politics, true crime and more. No need to worry about listening in order, each episode is a standalone!
Science Vs is a pod which takes on fads, trends, and the opinionated mob to find out what’s fact, what’s not, and what’s somewhere in between. Wondering whether you should drink detox teas like an insta-celeb, or believe your drunk uncle’s rant about gun control? Science Vs has an ep for that. Episode highlight: “SHARKS!!! Sink Your Teeth in Again” and “Climate Change… the Apocalypse?”
Ologies is a weekly science podcast hosted by Alie Ward. Each week, Ward talks with a different “ologist” from various scientific fields. The show’s tagline is “Ask smart people stupid questions”.
SciShow Tangentsis the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research… while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.
Genetics Unzipped is produced in association with The Genetics Society, and each week they bring you a new episode relating to genomics, genes, and everything related to DNA and/or RNA. Does genetics influence your personality? How can we test sewage for COVID DNA? How can we use ancient DNA to tell us more about modern species (including us)? Covering a broad range of topics and their intersection with genetics, this podcast is great for anyone who thinks genetics is cool, but might not be ready to delve into the nitty-gritty details and dusty old textbooks.
Climate crisis, climate justice and climate solutions
The climate crisis is scary and overwhelming, but it need not be hopeless! Here are a few podcasts that have left us feeling motivated and engaged in the search for solutions and understanding of the biggest challenge our planet faces today.
How to Save a Planet: Climate change. We know. It can feel too overwhelming. But what if there was a show about climate change that left you feeling… energised? One so filled with possibility that you actually wanted to listen? Join journalist Alex Blumberg and a crew of climate nerds, as they bring you smart, inspiring stories about the mess we’re in and how we can get ourselves out of it. How to Save a Planet is a really engaging podcast that focuses on climate solutions and those who are at the heart of them. It challenges preconceptions and makes complex topics understandable and accessible.
Drilled is a true-crime style podcast about climate change. The show was launched in 2017 and is hosted by investigative journalist Amy Westervelt who offers seasons long examinations of the origins of climate denial, workers who are suffering the impacts of climate change, fossil fuel propaganda and much much more.
The Yikes Podcast: There’s a lot to make us Yikes in this world. From the climate crisis to racism to activism and resisting oppressive systems, it can call get a bit overwhelming. The Yikes Podcast is a podcast hosted by two climate justice activists, Mikaela Loach and Josephine Becker, which leans into the Yikes of the world rather than letting it overwhelm us. They breakdown the issues in an accessible and nuanced way to guide us towards action together. Episode highlight: “What is Climate Justice?”

How unlikely it is to think that many people who decided to dedicate themselves to a natural sciences-related field wondered at least once about the life of an eighteenth-century naturalist?
Picture Alexander von Humboldt, Charles Darwin or Joseph Banks expeditions, or René Malaise and Gustav Eisen‘s impressive efforts in gathering human specimens and artefacts. How about Roderick Murchinson and his geological surveys around the world, or Hans Sloane, whose collections contributed to the foundation of London’s beloved British Museum? The imaginaries of explorers crossing oceans towards yet unknown territories, observing and sampling specimens never seen before, naming and using them to interpret the world, are striking, to say the least.
Nevertheless, other narratives are growing beside these settled imaginaries. It is increasingly recognised how those exact figures were far from the idea we have of them: solitary geniuses and intrepid explorers, nothing related to the politics and economies of their time. Instead, their journeys would rest on the routes of British imperialism, making use of the slave trade in the case of Sloane,1 or be sponsored by intelligence operations on foreign valuable minerals and local policies such as the case of Murchinson2. Even an important institution such as the Royal Botanic Garden in Kew now acknowledges how the boost that botanical research saw at the time was supported by interests in new profitable plants3. Likewise, it is recognised how the global network of botanic gardens emerged not only to create pleasant green spaces but also to have experimental facilities dedicated to researching those exotic new plants for valuable products. As a matter of fact, the search and cultivation of plants such as the rubber tree, a source of such a profitable material, or the Cinchona tree, from which the compound quinine was isolated and used against malaria by the occupying forces in the tropics, have been central to the expansion of the British empire4. The very same collection of animal, plant and human samples can be considered to be driven by similar dynamics. What was discovered in the colonised territories was taken, shipped to the collectors’ homelands, and then housed in centres that, in turn, expanded to accommodate the increasing flow of materials, being a source of knowledge for the benefit of their host institutions. This colonial dimension of the sciences that study nature remained unaddressed in the mainstream imaginaries, although some already glimpsed it. Like Sir Ronald Ross, a doctor engaged in the fight against malaria in the Sierra Leone colonies, who in 1899 publicly expressed how the success of imperialism in the following century would largely depend on success with the microscope 5.
Much has been written about “how modern sciences were built on a system that exploited millions of people, at the same time justifying and supporting it to an extent that greatly influenced how Western people view other ethnic groups and countries”6. At the same time, others point out that “one should not fall into the prospective error of asking nineteenth-century men to reason with post-colonial categories developed after World War II” 7. Likewise, those who work or are interested in these fields today might easily feel far from this legacy, either because of the time that has passed since that era or because of the desk-based nature of their research. Why think about it then? Wasn’t this a blog just about ecology and evolution?
Yet, systems linked to colonial trauma continue to shape the experience of many ecologists, naturalists, biologists, and even anthropologists, today. At the same time, many narratives are still influenced by worldviews that see the advances in the natural or biological realm as carriers of better health, civilization or culture. The consequences of these processes are tangible. A perspective article in Nature Ecology and Evolution8 speaks of colonialism in the mind first, referring to the way a Western scholar might relate to knowledge. From the simple use of language, as when talking about the Neotropical region (new to whom?), or the overwriting of Latin names, sometimes derived from the names of their European discoverers, to the traditional names by which some species are recognized, often more informative about behaviours or characteristics of that species. It could be through devaluating local knowledge, oral traditions, and artefacts that made it possible to navigate an environment in a surprisingly (for us) detailed way, relegating them to folklore or anecdotes, going so far as to claim scientific discoveries, for example, medical properties of plants, already known and shared by local communities for a long time. Fuelling the idea that any active ingredient or species is only really discovered when it enters Western scientific literature, even if they come from a non-systematic and oral knowledge that a population held for centuries.
Figure from Trisos et al. (2021). Map showing the minimum estimate for each country of the number of bird species for which the Latin binomial name is based on a European person.
Other than the mindset, inequalities are also visible on a very practical level: the scientific subordination of formerly colonised countries to researchers of the so-called Old World, better known as parachute or helicopter science. The role of local scientists has often been reduced as labourers employed in data analysis and collection for Western scientists. Adding to this, there are the issues with accessing that same knowledge produced in the ‘Global North’, either because samples or data are stored in museums or servers far away from the places they were collected, the absence of high-speed internet, the lack of the right networks, visa issues for accessing conferences9, or simply the high costs of publishing or even accessing scientific literature. Other ways in which parachuting occurs are through drawing on the traditional knowledge of these countries, when this is not belittled, cataloguing and publishing information without mentioning the contribution of local curators and experts.
Figure from Asase et al. (2022). Summary of the relationship between the number of authorships (i.e., representation as author or coauthor) on 9935 papers on “ecology” or “conservation” in Web of Science, for 2015–2020 versus per-capita gross domestic product (GDP).
Another important discussion is about climate change mitigation and rewilding projects when benefits that will be experienced globally demand costs to be felt locally, especially when adequate resources and support are not provided, or when measures impose worldviews external to local values and needs. The same article brings the example of a no-fishing zone established in French Polynesia which was detrimental to local fishermen’s needs, thus ending in simply not being respected and ultimately not helping the conservation efforts on the target fish stock. Top-down management of this kind proved itself to be not only erosive for people’s self-determination but also undermines the very objective of the project.
Many of the difficulties in the field of land management and nature conservation stem right from the relationship with local communities: other risks beyond not considering them (as in the case above), is romanticising them, possibly falling into the Western myth of the good savage, or assuming that indigenous people are willing to do what we ask. Rather, it would be important to recognize that like any human community, the local people we encounter during our work as scientists might have legitimate political, cultural and economic aspirations that could differ from our expectations.
Decolonizing the natural sciences is not a trivial matter. It certainly does not mean throwing away all that has been learned so far and starting afresh, making only use of ancient artefacts and indigenous tales. For many, it is a matter of reflecting critically on their profession, on the political context that allowed the development of each one’s work, on the power structures to which science might have contributed, taking dignity away from some bodies more than others. To “take a stand and recognize ourselves as part of the system we wish to describe, rather than as neutral actors, becoming aware of how backgrounds and training influence the questions that are asked, trying to understand how the data is interpreted and how our work might intersect with the power of companies or extractive interests over a place” 8.
Decolonization would not only be a matter of awareness but also make sure that research methods and implications are not in contrast with local values and management. This would certainly restrict researchers’ access or capacity for action, but it would be an important trade-off for all those who repeatedly had to give up their territories or lifestyles.
Discussions like this are indeed taking root. It happens when researchers use local languages alongside the traditional binomial taxonomic system, or initiatives are taken from established institutions, such as the case of the American Ornithological Society and its statement for changing harmful and exclusionary English bird names thoughtfully and proactively for species10. Or like the Biodiversity Heritage Library, now working to make their materials available in languages other than English11, the Pitt Rivers Museum12 and London’s Natural History Museum13, with their projects aimed at sharing the stories of colonialism behind their collections. More and more resources are becoming available for establishing healthy stewardships with indigenous communities14 or addressing parachute science15,16,17, or simply engaging with diverse experiences from diverse scholars18, 19.
On a side note (but not really), it is also worth mentioning the call for an intersectional approach to these challenges. Noticing how an individual’s capacity to contribute to public and scholarly discourse does not only rely on race/ ethnicity, but similar power dynamics might be in place based on gender, nationality, indigeneity, wealth, spirituality, sexuality, parenthood/dependencies and other identities. “An intersectional approach to practising ecology recognizes the multiple barriers and opportunities facing those working together”8.
These discourses might seem marginal to someone working now on their own seemingly unrelated passion project. Nevertheless, reflecting on how plants, animals, environments, and people intersected and influenced each other in different directions is indeed relevant.
Among all, it is the field of ecology and evolution that explores the relationships between living beings and the environment in which they live. Acknowledging diversity, not only in biological terms but also within systems of knowledge, solutions and stories of the people who are part of it – including their gender, ethnicity and nationality – is certainly a way to widen one’s lens on the world.

I am a visiting researcher at Trinity College Botanic Garden, working on the establishment of its long-term environmental monitoring program and interested in the human dimension of ecological systems dynamics. I wrote this post from the perspective of a western, female, early career researcher, and by no means do I wish to take ownership of the views of those who experience inequity and discrimination on a daily basis, nor do I believe this offers a complete or global understanding of such a complex problem. Rather, I hope to contribute to mainstreaming such an ongoing struggle, thanks also to the encouragement coming from discussing and comparing with peers.

An interview with basking shark researcher Haley Dolton
The basking shark, Cetorhinus maximus, is the second largest shark in the world and is regularly seen swimming off the coast of Ireland. But how much do we really know about these ocean giants? In this installment of the EcoEvo blog our co-editor, Lucy Harding sat down with PhD candidate and basking shark researcher, Haley Dolton to find out what it’s like studying these enormous sharks.
Lucy: So Haley, what was it about sharks that first got you interested in them?
Haley: I remember first being interested in sharks when I was reading an encyclopedia of animals and I read that sharks were fish! And that kind of blew my mind because of what I knew about sharks, they were more like mammals in my head; really powerful, can birth live young, can be social. So yeah, that really intrigued me. And when I started reading about them (because this was before the Internet!), and learnt more, like that they have these amazing senses, electrical senses, and they’re capable of doing amazing behavioural things, I think that really sparked my interest in sharks.

Lucy: What sets basking sharks apart from other large-bodied sharks, for you? Why study them over white sharks for example?
Haley: I know this sounds almost like a throw-away answer but I actually kind of fell into basking shark research, and then I grew to love them! It was the first opportunity that I was given to work in shark research in the Isle of Man, working with Manx Basking Shark Watch, and I just remember the first time I saw one I was like, “Oh my God, what is that?!” and it came right up to the boat, and I remember being shocked by the size of it! Any shark documentaries I’d seen, the only sharks really that were featured years ago were great whites because they’re the most *air quotes* “exciting” shark, but then I saw this basking shark, with the way it swims and what it looks like and I thought “Oh that looks like a great white but it’s massive!”. I think that that really sparked my interest in them.
I learned more about them from being in the field and reading about them, I was trying to figure them out because they didn’t make a lot of sense to me. For example, they feed on zooplankton (so they’re filter feeders) and they’re the second largest shark species capable of undertaking powerful behaviours, but they feed on microscopic prey, all of this got me thinking “How are they doing this?!”. So I got obsessed with how weird they are! Like how are they behaving like they do?! As another example, they aggregate in large numbers, and we don’t really know why!
(Haley scans the water hoping to spot a shark fin. Photo captured by Dr Nicholas Payne).
We think it’s maybe related to mating or for saving energy, as they swim close to each other, but you know seeing that in the wild, for yourself, it really sparks the ideas in the mind and that set me on the path to studying basking sharks over any other shark species. That’s not to say that I’m not interested in other shark species of course, but more that it was just circumstance which led me to basking shark research in the first place, and then I fell in love with how weird they were!
Lucy: Well, that’s a good point you make in that, for research, you don’t always have to follow a particular species or a particular project. If you more follow opportunities, you never know where they’ll lead you to, and it could lead you into something that interests you more than you realised!
Haley: Yeah, that’s it! When I went to the Isle of Man, I learned loads about research and what areas of research there were. So, for instance, we were doing satellite tagging and collecting DNA samples and this is what I actually wanted to go into at the time, I wanted to use DNA to carry out genetic research of shark species and look at the evolution of traits. And so, I originally started off being interested in that question and then when I saw that they were doing this amazing satellite tagging work, with behavioral and social studies, whether that’s on the human side, so looking at the impact of anthropogenic activity on basking sharks, or whether that’s the social side of the fish themselves, studying how they gather in large numbers! So, that’s where I first got introduced into loads of different scientific areas of research which focused on this one species.
“without knowing enough about your study species, you can’t effectively conserve them”
Lucy: So, are basking sharks an endangered species?
Haley: Yes, basking sharks are an endangered species. They’re endangered globally which means that they’re of ‘conservation concern’. The reason that we’re researching them, particularly in the Payne lab at the minute, is because we don’t really know a lot about what makes them tick.

We’re trying to learn more about them because without knowing enough about your study species, you can’t effectively conserve them. To give an example, imagine if someone was trying to conserve me and they saw one day – let’s pick a really bad day – where I’ve gone to the pub for hours, then eaten a pizza, and I haven’t really moved a lot. It might make people think, that’s all I do so let’s give her that all the time! Well, I wouldn’t last very long! I’d have a great time, but I wouldn’t be very healthy.
And that’s why we study these animals, to get as much information as possible to really affect conservation policy and change because these are vulnerable species.
There were massive fishing industries for them, including in Irish waters, and although we no longer have those fisheries, they’re still very vulnerable to being accidentally caught in things like pot lines or in other fisheries related equipment. They are a vulnerable species to lots of kinds of anthropogenic activity, making conservation efforts even more important.
Two basking sharks swim underwater, off the West coast of Ireland (photo captured by Haley Dolton).
Lucy: And you said they are filter feeders and very large, so does that make them a difficult species to study?
Haley: Basking sharks are an unusual study species for sharks, in that we can’t fish for them or attract them to the boat, so we can’t research them in the ways we would with other species where you can do that. So, we’re very dependent on where and when they turn up and whether there’s a good weather window for us to get out and study them, which off the Irish coast is quite rare! So, everything needs to come together to allow us to go out and study them and in reality, I only have around six days to get my tags deployed, which just highlights how difficult they are to study.
Lucy: What does your current research on basking sharks focus on?
Haley: My current research really focuses on getting back to basics of what we know about the general biology of these animals. For example, looking at their anatomy, whether that’s the larger structures or microscopic features. I’m looking at how their anatomy can explain their behavior. So, as I said there’s so much we don’t know about basking sharks.
At the minute, off the Irish coasts, we’re getting hundreds of them in the spring and then later on throughout the summer, and they’re displaying this amazing behavior where they all gather and swirl around each other, which we think might lead to mating, but ultimately we don’t really know why they display this behaviour! So, my research is really focused on trying to explain these behaviors by looking at their anatomy and physiology and what we as scientists, the general public, or policymakers, can do to effectively conserve this species in Irish waters.
“it’s a really exciting time to be part of basking shark research in Irish waters”
This is all going on at an exciting time for basking sharks in Irish waters! Recently it was announced that they’ll hopefully gain protection under the Irish Wildlife Act and there’s been incredible public support for this in Ireland so it’s a really exciting time to be part of basking shark research in Irish waters and to hopefully make a positive change within their conservation.
Lucy: And when you’re out in the field, how do you actually study these animals?
Haley: Well, firstly we work closely with other researchers and the general public who very kindly tell us where and when they see the sharks; we’ve had loads of great sightings (and skippering of boats!) from the Irish Whale and Dolphin Group (IWDG) and individuals from different tour operators off the Irish coast like West Cork Charters (Dave Edwards) and Nick Masset (also part of IWDG), whose based near the Blaskets in Dingle, and of course, social media, which tells us where and when sharks have been seen. Then, we’ll scramble to get all our field kit ready and head over to the West Coast!
Normally with shark research we go out to a place where people are already fishing for sharks (for catch and release) or where we’re fishing for them for scientific research and this normally involves attracting them to the boat (with bait) but because we can’t do that with basking sharks, we basically drive the boat up and down the coast slowly, surveying with binoculars to try and spot that characteristic fin sticking out of the water.

Lucy: And so, when you do spot a fin, what happens next?
Haley: In basking shark research we actually deploy the biologgers without touching the shark at all (apart from the actual deployment itself). We carefully approach the shark in the boat, deploy the tag, and then we’re off again! This all takes a matter of seconds, so that we’re actually only beside the animal for a couple seconds as we deploy the biologger. Some sharks don’t even react at all, they just carry on swimming or feeding at the surface, which is a good indication they haven’t been disturbed.
I should point out that any research we do on sharks is conducted under license from the HPRA (Health Products Regulatory Authority) ethics board for animal studies, as to not cause stress to the animals.

Lucy: How is your research going so far? What are your plans going forward for the research?
Haley: The research that is focused on basking shark biology, ecology and behavior has gone really well so far and we’ve found out some really, really interesting things which I’m dying to talk about but I can’t at the moment, but watch this space! There’s lots of cool stuff coming soon!
My research interest has grown from my supervisors, Nick Payne, Andrew Jackson and Jonathan Houghton, supporting my curiosity for this species and a collaboration I made when I first started shark research all those years ago (Jackie and Graham Hall who ran Manx Basking Shark Watch). Now this project is growing and we’ve established new collaborations with some incredible researchers from Oregon State University (Big Fish Lab) and Stanford University, who came over this year for fieldwork. Together, we’re trying to collect and analyse even more data about what the sharks are doing and how they’re behaving. There’s been lots of steep learning curves with doing this research as well, but overall, it’s gone really well and we found out some really cool stuff, which will hopefully come out soon!
“if you do see something, take lots of pictures”
Lucy: That’s great, I can’t wait to see what you’ve found out! Well, for my last question, as a lot of our readers may not necessarily be in the scientific field, is there any way they could get involved in conservation efforts or research to help these threatened sharks?
Haley: Yes! People can get involved by reporting their sightings of any sharks to groups such as the Irish Basking Shark Group and Irish Whale and Dolphin Group and these can feed into scientific research. Also, if you do see something, take lots of pictures because then it’s possible to identify individuals by nicks and cuts on their dorsal fin and this is a great example of a non-invasive way of looking at social behavior or whether sharks are returning year on year to an area, indicating it might be an important area for feeding or breeding or pupping.
You can also get involved with any campaigns that you see going on for the protection of these animals. Support from the public, alongside the work and support from Minister Noonan and TD Jennifer Whitmore is actually what was instrumental in the recent campaign to have the basking shark added to the Irish Wildlife Act; it was a great campaign led by the Irish Basking Shark Group to get basking sharks protection in Irish waters and part of that was a petition that was signed by the general public. It gained incredible support from the public, with I think over 20,000 signatures, which is amazing and hopefully they’ll be protected under Irish law soon.

After a hiatus during which the Symposium had to move online, the annual TCD Botany-Zoology Postgrad Symposium finally made it’s return to an in-person format at the start of June 2022 for its 11th edition. It was a great opportunity to for the departments of Botany and Zoology to come together and hear about the wonderful research that is being carried out around the School of Natural Sciences. For some of us, it was our first time meeting certain people in person after many Zoom calls. The range of research that was showcased spanned from sharks to social media, and detoured through seaweed and the ever present climate change. We were delighted to welcome two guest speakers, Dr Anthony Heijenga from GIA Consultancy and Dr Katie O’Dwyer from the newly rechristened Atlantic Technological University, who brought in their unique perspectives on research.
The organising committee of the 2022 Botany-Zoology Postgraduate Symposium: Niamh Mc Cartan, Floriane O’Keeffe, Kate Harrington, Richa Marwaha and Diego Bianchi.
The Symposium kicked off with the first of our plenary speakers, Dr Anthony Heijenga, who gave us a fascinating insight into what you can do with a biology degree. Between growing plants in space, flying in zero gravity and watching exploding rockets, there was plenty to keep the audience entertained. Anthony also gave us an overview of his work on plants and the challenges of growing plants in space.
Dr Anthony Heijenga presenting his talk entitled “Advanced Life Support Systems”.
After our first plenary speaker, it was on to our student presentations. First in the session was Haley Dolton, a third year PhD student in Dr Nick Payne’s lab, who presented her research on investigating the anatomy and physiology of basking sharks to understand why they behave the way they do.
Following Haley was Romane Guernalec, a masters student and intern in the Botany Department, supervised by Dr Matt Saunders. Romane works on methane fluxes from aerenchymous species (specifically Typha latifolia) in restored peatlands, and presented her plans for her fieldwork in Ireland.
Next up was Marine Valmier, a fourth year PhD student supervised by Dr Matt Saunders, who is looking at the impacts of management and warmer temperatures on the carbon balance of a grassland on peat soil (assessed with Eddy Covariance technique).
Following Marine, we heard from Frank Spellman, who is a second year PhD student in Zoology supervised by Nessa O’Connor. Frank is applying ecological theory to improve the stability of yields of cultivated macroalage, and quantifying the ecological impact.

We then heard from Eamonn Cooper, a first year PhD student in Botany who is supervised by Trevor Hodkinson. Although Eamonn only started two months ago, he gave a great overview of his project which will be looking at the genetic characteristics of plus crop oak and their progeny.
Next up was Aedín Mc Adams, who is doing a research masters in Zoology with Prof Yvonne Buckley. Aedín is assessing the habitat suitable for restoration and reintroduction of Geyer’s Whorl snail 🐌 (Vertigo geyeri) in Lough Talt in the Lough Hoe Bog SAC.
Closing out the Thursday afternoon session was Thibault Durieux, a first year PhD student in Botany supervised by Dr Carla Harper. Thibault spoke to us about the first steps of wood evolution about 400 million years ago and its relationship with past ecosystems.
Eamonn Cooper, Aedín Mc Adams, Thibault Durieux and Mairéad O’Donnell presenting their research.
We were back bright and early on Friday morning for a packed day of talks. First to speak was Mairéad O’Donnell, who is a first year PhD student in Botany supervised by Dr Marcus Collier.
Next up was Floriane O’Keeffe, a third year PhD student in Zoology who is supervised by Dr Pepijn Luijckx. Floriane spoke to us about the effects of parasitism in Daphnia magna, specifically looking at the effects of sequential versus simultaneous co-infections in these animals.
Following Floriane, we heard from Midori Yajima, who is supervised by Prof Jenny McElwain. She spoke to us about how botanic gardens’ potential for climate change research is yet to be fully explored. Trinity College Botanic Garden has a 10+ year environmental monitoring program which aims to contribute to filling this gap, and its year one baseline work is now underway – addressing the what, how, and which species will be protagonists for this long term challenge.
Next up was Elena Zioga, a final year PhD student supervised by Prof Jane Stout. Elena presented her research on characterising systemic pesticide residues in floral resources for bees in Ireland.
We then heard from Grace McNicholas, a first year PhD student supervised by Dr Nick Payne. Grace presented her plans for her PhD project, which will be investigating environmental drivers and habitat suitability of a renowned ocean predator, tuna.

The final speaker of this session was Bea Jackson, who is supervised by Prof Jenny McElwain and Dr Carla Harper. She is working on using fossil plant trait to aid with reconstruction of atmospheric CO2 concentration during the Devonian period.
After a quick coffee break in the sunshine, we were on the second session of the day. Our first speaker was Andrew Neill, a third year PhD student supervised by Prof Jane Stout, who presented his project discussing how social-media can provide insight into people-nature interactions to better map and assess cultural ecosystem services.
Next up was Kathleen Conroy, who is a first year PhD student supervised by Prof Jane Stout. Her work will enable land managers to make important decisions that will have lasting effects on Irish forests.
We then heard from Clinton Haarlem, a second year PhD student supervised by Dr Andrew Jackson, who gave a talk which was intriguingly entitled “Time is in the eye of the beholder”. Clinton gave an overview of his research investigating what might cause variation in individuals’ “temporal resolution” (the ability to process different rates of change in luminance).
Bea Jackson, Andrew Neill, Kathleen Conroy and Clinton Haarlem presenting their research.
Next to speak was Irene Bottero, a final year Botany PhD student who is supervised by Prof Jane Stout. She explained to us that landscape degradation is one of the main causes of insect pollinators decline, and that preserving landscape diversity and semi-natural habitats (including floral strips and hedgerows) is fundamental to preserve pollinator communities in agricultural contexts.
Our next speaker was Whitney Parker, a first year PhD student supervised by Dr Pepijn Luijckx. She gave an introduction of her PhD, which will investigate the effect of host density and genetic diversity on the spread of infectious diseases, using Daphnia magna as a model organism.
The final speaker of this session was Andrew Torsney, a PhD student in Zoology supervised by Prof Yvonne Buckley. He presented his research on the environmental impacts of visitors at nature-based sites, and explained that visitor demongraphics, site-type and activities determine the occurrence and severity of environmental impacts at these tourist destinations.
Our final session was opened by Simon Benson, a first year PhD student in Zoology, supervised by Dr Nessa O’Connor. He presented his PhD project which will investigate the development of high-value products for economically viable kelp aquaculture using genetic, ecophysiological, and biochemical methods.

Next up was Kate Harrington, a first year PhD student supervised by Prof Jane Stout and Prof Fraser Mitchell. Kate is investigating the ecological value and ecosystem services of new native woodlands.
We then heard from Niamh Mc Cartan, a first year PhD student in Zoology who is supervised by Dr Pepijn Luijckx, who presented her project looking at the effect of extreme temperature variation on host-parasite interactions.
Natalia Rodriguez Castenado, supervised by Dr Marcus Collier, then presented her project, entitled Embracing wild and restoring minds: qualitative approaches to urban wild spaces and mental health and well-being in sustainable cities.
Our final student speaker of the Symposium was Katrin Schertenleib, a final year PhD student in Zoology supervised by Dr Nessa O’Connor. Katrin explained how Bayesian Belief Networks function, and how we can use them to assess the ecological status of Dublin Bay.
She closed her talk by reiterating to the audience how important climate change mitigation measures are, especially in such uncertain times.

The wildflower meadow outside the front gates of Trinity College Dublin.
In February 2020, a Trinity Green Campus poll was held amongst Trinity College Dublin (TCD) staff and students to convert the lawns of Front Gate into a wildflower meadow. Of the 13,850 people who voted, 12,496 voted in favour, a 90% majority. This was the largest number of participants that Trinity Green Campus had ever had, likely due to the extensive communications regarding the campaign, with features being included on local, national, and international news channels. The project has been deemed a success with support from both the public and TCD community and it continues to flourish outside the historic Front Gate of TCD. The TCD wildflower meadow is one of many similar “rewilding” projects that are currently being undertaken to increase biodiversity in urban and rural spaces but why are they such a popular rewilding choice? And how can we ensure their success?
Let’s take it that any project, ecological or otherwise, can be deemed successful if it has fulfilled the goals that it set out to achieve. The majority of rewilding and restoration projects aim to introduce species to an ecosystem as a way of restoring ecosystem functions and re-establishing natural processes that existed previously. In the case of wildflower meadows, the species being introduced are herbaceous plants and the ecosystem functions that they aim to restore usually relate to pollination or biodiversity, although this is not always the case. Even the broadest generalisation of the aims of wildflower meadows lacks clarity on the type of ecosystem functions that are expected to be restored. This is due to the aims of any restoration effort being dependent on the social and cultural views of the people carrying out or interacting with the project. Therefore, each individual wildflower meadow project must define the unique aims pertaining to it before a decision can be made on its success.
The two most documented spatial differences are between North America and Europe. In North America, the landscapes that were present before European colonisers have long been idolised and perpetuated as the “perfect wilderness,” with many attempts being made to conserve and restore these ecosystem types. As such, projects which aim to restore pre-colonisation landscapes are often deemed to be successful and are well received by the public. Large wildflower meadows that are re-planted in areas that previously were inhabited by similar species and vegetative communities are also deemed successful and serve as a reminder of the great prairies and grasslands of 1500’s North America. However, when urban wildflower meadows are planted many North Americans question whether it is truly restoration, since there were no previous wildflower meadows present here which can be said to be restored. Therefore, if the aim of this example is to be an act of restoration or rewilding the project is unable to be successful.
Contrasting to this, European rewilding does not explicitly try to recreate a single period, owing to the long established agricultural and industrial disturbance that has been occurring in the area since ~7000 B.C.. Therefore, the matter of projects emulating an exact period does not cause the same obstacles to success that are seen in North America. Instead, a range of dates are replicated, from Pleistocene to pre-industrial. There is a much lesser demand for projects on the large scales seen in North America, with the reintroduction of large carnivores causing public outcry. When concerning wildflower meadows, small pockets of pre-existing meadows or similar habitats are still naturally established in Europe, such as hedgerows and agricultural wildflower meadows. Thus, it is easier for people to view wildflower meadows projects as restoration.
Education also plays a key role in the success of wildflower meadows. Some studies have shown that the public perceives nature as consisting of trees and forested areas, and so projects that remove trees, even for positive environmental reasons, are perceived negatively. Other studies, however, have shown contrasting results, recording preferences towards annuals over larger trees or fruit plants. Interestingly, this same study also recorded that 54% of participants did not know what wildflowers were. This indicates that asking the public whether they prefer wildflowers over trees may not give accurate data as the responders are much more familiar with one subject over the other. Where images were shown, participants revealed a preference for wildflower meadows over images of herbaceous and formal bedding styles. The degree to which they preferred wildflower meadows over other bedding styles increased with an increase of plant species richness. This is a positive sign for those who wish to use wildflower meadows to restore pollinator and biodiversity functions, as it suggests that there should be public support of the projects if the public are adequately informed on wildflower meadows.
The TCD wildflower meadow project had clear goals, aiming to demonstrate that grass lawns were not the only option for planting in a formal setting. By prioritising the goal of informing the public on the project aims, TCD reduced arguments that may have otherwise arisen over the success of the project. Notably, before the project began, the idea was put to a vote by the staff and students at the college. As mentioned previously, the poll was hugely successful likely due to the amount of publicity it received. In order to combat any doubt surrounding the use of non-native species, information was provided about the reasoning for including non-native species and why they would be beneficial to the project, for example, the increased pollination potential of the site and the aesthetic benefits of the species chosen. The clear communication regarding the project appears to have ensured the wildflower meadows success. The public support for a wildflower project in the heart of the capital city centre could also in part be due to the site being in Europe. Alternatively, the public support could be due to the project being planted shortly before the Covid-19 pandemic, which has been hypothesised to have increased public appreciation for green spaces. Many of the questions posed remain unanswered due to the modernity of the topic and rapidly shifting public opinions. As developments occur, both academically and publicly, more light will be shed on the success of wildflower meadows and how projects can be best implemented. However, for now, debates on the topic should be encouraged and the public should be involved in the conversation. Wildflower meadows have a huge potential to educate people about their environment and can be implemented on many scales, being made suitable to whichever environment is present. The people managing these projects should consider the ecological and social environment within which they work and make efforts to adapt to the unique environment in which they may find themselves. There is plentiful research into the social dynamics of rewilding and restoration projects and so it can be concluded that the issue lies with project managers and a potential lack of consideration of the social factors at hand.
