Title: How population density influences social mammal ecology: A case study of the European badger.

The local density of a population of social mammals can affect many aspects of its ecology including social structure, mating systems, dispersal behavior, territorial behavior and the dynamics of disease. Scientists and policy-makers need a comprehensive understanding of the local population density as this may dictate the most effective management strategy. The European badger provides a particularly good species to investigate the effects of population density on other density parameters because its density varies by orders of magnitude across its wide geographic range. Further, it acts as a wildlife reservoir for bovine tuberculosis in the UK and Ireland, where it is subject to control operations. Currently, a haphazard classification of local population densities hampers a clear understanding of the badger’s ecology, leading to inappropriate management systems. We have conducted a meta-analysis to investigate the relationships between social group size, territory size, and group density and population density in badgers. We demonstrate that population density fundamentally alters badger ecology, affecting the interactions both within and between social groups. We also propose a classification system for densities of the European badger which highlight important ecological differences between populations across the density spectrum. Our findings provide a more cohesive picture of the species’ ecology across its range, facilitating appropriate targeting of disease management and conservation regimes.

Title: Characterisation of endophytic microbes within Sphagnum magellanicum from Clara Bog, County Offaly, Ireland: Implications for enclosed environment hydroponic systems in Space.

This work investigates potential mutualistic relationships between endophytic microbes and species of native Sphagnum moss sampled from Clara Bog, County Offaly, Ireland. The application of the ion-exchange ability of Sphagnum moss to water remediation and recourse recovery within an enclosed hydroponic system has been investigated by the author at NASAs Space Life Science Laboratory, Kennedy Space Centre, Florida. While this research indicated that Sphagnum could be utilized in this manner, it resulted in yet more questions, specifically in relation to microbial interactions and growth mechanisms within the Sphagna:plant test bed.

It is postulated that endophytic microbes growing mutualistically within S. magellanicum may be responsible for (a) anti-algae and anti-microbe effects within the hydroponic system and (b) increased nutraceutical content within the associated salad crop. Microbial DNA isolated from 100ug samples of S. magellanicum, was extracted and used to identify microbial endophytes using standard barcoding primers. Genetic fingerprinting is being utilised to type the endophytes. Isolation and culturing protocols from Sphagnum plants have been developed and applied for the characterisation of microbial species during hydroponic systems using S. magellanicum as a growth medium. Further investigation of mutualism between identified endophytes and a cultivar of Lactuca sativa known as ‘Lollo Rosso’ is ongoing.

Title: The effectiveness of renewable energy policies in encouraging renewable energy generation.

Over the last twenty years the EU and its individual countries have been engaged in implementing policies to increase the use of renewable energy (RE) as a generation source. Motivations for this support of RE generation include, but are not limited to, concerns over climate change and pollution, national security risks associated with fossil fuels, and a wish to increase the competitive position of RE in markets which have been traditionally dominated by carbon based power. The issue of climate change and renewable power’s role in addressing this complex challenge has, in particular, been brought into sharper focus following agreement on emissions pledges from all the EU countries, and a new target of keeping global warming below 1.5C in December 2015 in Paris at COP 21; targets which will require a material response by policy makers throughout the EU. An understanding of what policies have been most effective in increasing RE is therefore critically important in designing new schemes, a comprehensive analysis of which has not been completed to date. I am therefore conducting a comparative analysis of the effectiveness of RE policies in encouraging RE generation (solar and wind, which given their advantages in cost and deployment have been the dominate focus of policy) across the EU from 1995 to 2015, with a primary focus on four countries of contrasting contexts, Ireland, UK, Italy and Portugal. While several studies have attempted to determine the effectiveness of various policies in various countries, these have been limited in scope and have not attempted to account for the variety of policy design features or individual country, market and key actor characteristics that influence policy strength. Adopting an energy transitions theoretical framework, this research would constitute the first study undertaken to determine how policy has effected the growth of renewables across Europe.

Title: Systematics of the genus Embelia Burm.f. (Primulaceae – Myrsinoideae)

Within the Primulaceae family, the Myrsinoideae form a highly variable tropical group, ranging from climbers and shrubs to trees, and characterised by the presence of dark dots on the leaves and fruits. This subfamily contains over 1300 species, divided into approximately 40 genera. Many of these genera are in need of taxonomic revision, as their limits are poorly defined and sometimes rely on ambiguous characters. Among these genera is Embelia, a genus of climbing shrubs distributed mostly in South and South-East Asia, tropical Africa and Madagascar. Embelia displays extensive morphological variation – especially regarding the position, shape, size and merosity of the inflorescences and flowers. It is distinguished from other Myrsinoideae only by the climbing habit, and the relationship with morphologically similar genera has not been critically evaluated yet. The last monograph of Embelia by Mez (1902), recognised eight subgenera and 92 species, but the total number of species is currently estimated at 150-200, and the subgenera used by Mez must be assessed and refined. My project aims to combine morphological and molecular data in order to test the monophyly of Embelia and to provide a taxonomic framework of the subgenera.

Title: Toll-Like Receptor Gene Expression During Early Murine Embryonic Development.

Toll-like receptors (TLRs) are renowned for their fundamental roles in immunological surveillance and response initiation. While TLR proteins in invertebrate species, such as Drosophila, carry out functions in the immune system and in “building” the body plan in the embryo, such non-immune functions have not been thoroughly investigated in mammals. Although TLR genes have duplicated independently in these lineages, and may therefore have diverged in aspects of their functionality, limited studies have recently reported the expression of TLRs in the developing mammalian embryo (Kaul et al., 2012). We report a systematic study of Tlr gene expression in early to mid-gestational murine embryos using whole-mount RNA in situ hybridization and 3D imaging (using Optical Project Tomography), the combination of which has allowed us to record the precise tissues and stages at which these genes become expressed. We have found that the expression of these receptors is particularly enriched within the central nervous system with many Tlrs displaying complementary expression patterns in developing neural tissues, as is the case with Tlrs -1, -5, -6, and -7 in the neural tube at embryonic day 10.5. These findings are in line with experimental data showing that Tlrs -2, -3, and -4 can influence neural progenitor cell proliferation and self-renewal (as reviewed in Barak et al., 2014). In addition to the expression data we have generated, whole-transciptome data is being mined to build a comprehensive picture of Tlr activity during embryogenesis and will aid in the building of specific hypotheses for functional testing.

Title: Do principals of cross congruence apply in a naturally disturbed habitat?

Cross congruence is a measure of the degree to which diversity (number or composition of species) of different taxa follow broadly similar patterns in response to environmental conditions. In situations where cross congruence is strong, measuring the diversity of a single taxon can provide information regarding overall diversity, and this has led to the development of indicator taxa. Indicator taxa may be used to indicate general patterns of biological diversity or environmental conditions, often with the inference that where the environmental conditions are favourable for one taxon, other target taxa will benefit. The use of indicator taxa has obvious economic appeal, but cross congruence has been shown to vary greatly in different studies. Habitat heterogeneity and environmental stress can reduce the correlation of diversity among different taxonomic groups.

Within the EU, states which have signed up to the Habitats Directive (Council Directive 92/43/EEC) monitor the condition of habitats of conservation concern (Annex I habitats) using standard methods and report their results to the European Commission. Indicator species are used as part of this habitat assessment. Dune slacks, an EU Annex I habitat, are temporary ponds in sand dunes which can persist for long periods, many having been formed as part of the initial dune-building phase. Despite being stable physical features, they experience both environmental stress (annual flooding and desiccation) and temporal habitat heterogeneity, and this raises questions: do principals of cross-congruence apply here, and are indicator species effective? This study compared patterns of diversity among three different taxonomic groups, to test whether cross congruence was observed. Communities of plants, snails and water beetles in twenty-four dune slacks in Ireland were compared using diversity indices and ordination techniques. Dune slacks were assessed on the basis of the indicator species used in reporting to the European Commission, and the biological assemblages of sites which passed and failed the assessment were compared. The results of this research will help to evaluate current monitoring techniques which are in use throughout the EU and guide monitoring approaches for dune slacks in Ireland.

Title: Stronger perturbations increase the complexity of ecological stability

The stability of ecosystems determines the sustainability of the biological resource and services that nature offers us, and an understanding of mechanisms and drivers of ecological stability has vast implications for the sustainability and management of natural resources as well as the protection and restoration of ecosystems. Much effort has been contributed to understanding the factor that determines the stability of biological communities. A challenging aspect of stability is its many components, including asymptotic stability, resilience, resistance, robustness, persistence, variability and so on, but most of the previous research failed to analyse ecological stability from an comprehensive angle and we know remarkably little about the mechanisms underpinning relationships among components of stability. Therefore, focus on single stability elements may cause an underestimate of the “real stability” of ecosystems. Here in our research, by simulating the dynamics of 13 four-species food webs following perturbations varying in strength, we show that stronger perturbations decouple the relationship between stability components, i.e. that the efficacy of the single stability element in representing the general character of ecological stability becomes lower under strong perturbations. It is therefore necessary to investigate ecosystem stability from multiple angles, especially under strong disturbance frequently shown in real nature. The decoupling effect of perturbations on the multidimensionality of ecological stability is universal across most of the 14 food-web motifs in our research, implying a similar pattern in more complex large ecological networks.

Title: Population dynamics of Pinus and Ulmus in Europe during the Holocene.

This work investigates and compares the population dynamics of Pinus and Ulmus in Europe, during the Holocene, at varying temporal and spatial scales, by using recently developed and novel modelling methods. The first component characterises the European-wide post glacial rise and mid-Holocene decline experienced by both genera. Pollen data was extracted from 330 sites on the European Pollen Database (EPD). The depth of rise and decline events for each genus in each site core was defined by applying a spline curve, to remove stochastic noise from the pollen data, and identifying the range of depths along which the pollen values increased or decreased.

The R package Bchron was used to calibrate radiocarbon dates and produce an age-depth model for each site, using stochastic linear interpolation and Monte Carlo methods. The age-depth model data was applied to the event depth range to produce a probability distribution of when the rise and decline events occurred.

The second component characterises Ulmus and Pinus when they were abundant on the European landscape. Depth and magnitude data of maximum pollen values for both genera were gathered from the EPD. The age-depth models were used to determine the age of the maximum pollen value depths.

These data were then plotted on maps and empirical Bayesian kriging was used to interpolate the spatial and temporal dynamics of these population events in the two tree genera. This work, therefore, presents novel techniques to quantifying tree population dynamics, and also provides insight into the specific dynamics of two major tree genera in Europe.

Title: Phylogenetics of Camellia (Theaceae) in Indochinese Peninsula

Tea, camellias and oil camellias from the genus Camellia L. (Theaceae) are commercially highly important. About one third of all known Camellia species occur in the Indochinese Peninsula, of which half are endemic. Many new names of Camellia are still being described from this area, which may suggest that it was previously under-collected. Almost no work, however, has focused on the phylogenetics of Camellia in this area. This project aims to address these issues using morphological and molecular approaches. Morphological studies, consisting of a comparison and description of various macro-characters of specimens and palynological analyses, will be undertaken to clarify the boundaries of species in this notoriously variable genus. DNA markers derived from nuclear and chloroplast genomes will be selected to generate molecular sequence data, which will be used to reconstruct a robust phylogenetic tree. A new classification of this genus could then be proposed based on both morphological and molecular data. Species that have potential to supply new traits to the cultivars of tea, camellias and oil camellias could also be identified.

Title: Biodiversity in willow evapotranspiration systems for wastewater treatment

Constructed wetlands are increasingly seen in Ireland and abroad as a solution to the on-site treatment of wastewater from domestic and other sources in rural areas. They are likely permanent features in our landscape that will proliferate into the future. Willow evapotranspiration systems are a subtype suitable for application in areas with low permeability subsoils. These systems are often promoted as having a beneficial role with respect to biodiversity but this has not been rigorously evaluated. This project aims to assess the plant and invertebrate biodiversity of these systems and the contribution they make to the biodiversity of the wider landscape. The factors driving biodiversity in these systems are being investigated and thus this project will provide management recommendations to maximise this biodiversity. This project involves cross discipline collaboration, drawing on expertise from both the TCD School of Natural Sciences and the TCD School of Engineering.

Title: Ecological character displacement as a driver of diversification

Since Darwin, competition has been recognised as an important factor driving diversification. Competition is energetically expensive and unstable, so direct competition is rarely observed. One way in which species can avoid competition is ecological character displacement. This is where differences between similar species are accentuated when they co-occur but are lost or minimised when they do not overlap.

We suspect this process may have occurred in our study system of south-east Sulawesi, Indonesia. Two closely related and similarly sized species of kingfisher occur in this region, one resident and one migratory. On the Sulawesi mainland and larger (continental) islands they spatially segregate by habitat and resource partitioning. On the smaller islands of the Wakatobi Archipelago there is less habitat diversity and we do not see evidence of either habitat or resource partitioning. We do see a shift in morphology of one of the competing species, the resident Collared Kingfisher (Todiramphus chloris). The Wakatobi population is larger (wing and bill) than mainland populations. The change in habitat structure on the Wakatobi Archipelago bringing these species into closer contact may have promoted this divergence in morphology to alleviate potential competition.

Preliminary genetic work shows divergence between Collared Kingfisher populations of the Wakatobi and Sulawesi mainland, indicating the taxonomy of these populations requires further assessment.

Title: Morphological characters of Henckelia Spreng (Gesneriaceae)

The genus Henckelia is one of the most complicated genera in the family Gesneriaceae. Recent molecular phylogenetic studies on Chirita and Henckelia are presented. These have separated Chirita from other genera such as Henckelia, Damrongia, Microchirita, Liebigia and Primulina. Some members Henckelia have been moved to other genera including Codonoboea, Didissandra, Didymocarpus, Lindernia and Loxocarpus resulting in a reduction in the number of Henckelia species to 57. Defining morphological characters for Henckelia allowing separation from these other genera are as yet unclear but will be derived from materials collected on fieldwork. In addition, for these morphological studies, specimens lent from Aarhus University Herbarium (AAU), University of Aberdeen (ABD), The Natural History Museum (BM), The Forest Herbarium (BKF), Bangkok Herbarium (BK), Royal Botanic Garden Edinburgh (E), Royal Botanic Gardens (K), Kunming Institute of Botany (KUN), The National Herbarium Nederland (L), Singapore Botanic Gardens (SING) will be used. The final thesis will therefore be in part molecular but with palynological, ecological, morphological and biogeographic data. This will allow for a revision of Henckelia in Thailand and Indo-China including Myanmar and Southern China.

Title: Now you see me: Examining the variation in time perception

Sight is one of our most valuable senses: constantly feeding us information about our environment, allowing us to evaluate potential mates, and perhaps most importantly: enabling us to find food. In the animal kingdom, a number of strategies are deployed as individuals and groups go about finding the food necessary for moving, growing, and ultimately passing on ones genes.

The way in which animals and humans acquire, process, and act upon visual information is a highly evolved, intricate process played out over minuscule time scales. In the time it takes for a predator to realise that its prey is about to change direction, or for an expert batsman to notice the spin on an approaching baseball, it is often too late to act. Our knowledge of temporal variation in this key trait lag in comparison with our understanding of spatial acuity.

Using a combination of simulation and psychometric techniques, I aim to tease apart the relationship between information acquisition over discreet temporal scales and the evolutionary consequences for both animal and human systems.

Title: Characterizing candidate disease resistance loci in ash (Fraxinus) and an assessment of ash fungal endophyte strain variation in Ireland

Ash is very useful and abundant tree found throughout Europe, which is now threatened considerably because of a disease called ash dieback. It is caused by a fungal pathogen known as Hymenoscyphus fraxineus Baral. It can damage plants irrespective of their age group but young plants are more susceptible to the disease. Ash dieback starts from the midrib of the leaves and travels through the midrib to the stem part of the plant where the fungal mycelia blocks the xylem and phloem vessels and the plant dies because of lack of water and nutrients. This project is currently undertaking a comprehensive study of the leaf fungal endophytes of healthy plants to characterize their microbiome. We have cultured endophytes in a malt extract agar media and isolated them on the same media by sub-culturing. We are currently amplifying nuclear ribosomal bar coding DNA regions and sequencing them to identify the fungal isolates. We will then test the biocontrol potential of some of these against the disease pathogen.

Title: Does parasitism interact with warming to modify energy flow in ecosystems?

Gammerid amphipods are key components of aquatic ecosystems around the globe, acting as important detritivores and frequently dominating benthic assemblages in both rivers and lakes. Their ability to process detritus and return nutrients to the ecosystem may, however, be undermined by infection with behaviour-modifying acanthocephalan parasites. Moreover, as gammerids are ectothermic, the impact of parasitic infection could also vary with temperature. We explore whether parasitism and warming interact to modify energy flow in ecosystems by comparing individual energy budgets for Gammarus duebeni that were infected with the common acanthocephalan parasite Polymorphus minutus, with those of uninfected individuals of similar size across a broad range of temperatures.

Room for one more?: Egg fostering in seabirds

When attempting to conserve a rare animal population sometimes every individual counts. Conservationists regularly go the extra mile to protect their study species. The conservation efforts implemented for the Little Tern (Sternula albifrons) in Britain and Ireland demonstrate the success these efforts can have. This species nests on shingle beaches and had experienced catastrophic population declines due to increasing development and use of beaches by people. Little Tern adults are very vulnerable to disturbance and their eggs are particularly vulnerable to walker’s boots! Thankfully a network of wardened colonies, run by a mixture of conservation organisations and enthusiastic volunteer groups, succeeded in stabilising this species’ population.

The Evolution and Laboratory of the Technician.

First in a series of posts on life after an undergraduate degree, Alison Boyce gives an account of the life of a scientific technician.

Science, engineering, and computing departments in universities employ technicians. Anyone working or studying in these areas will have dealt with a technician at some point but most will be unaware of a technician’s route into the position and their full role in education and research.

Technical posts are varied e.g. laboratory, workshop, computer. Funding for technical support is afforded by the Higher Education Authority (HEA) to provide assistance in undergraduate teaching. This is the primary role of technical officers (TOs) after which the Head of Discipline or Chief Technical Officer (CTO) decide further duties.

History

Until the early 1990s individuals joined the university as trainee technicians. Many came through the ranks starting as laboratory attendants, a position which still exists. Trainee technicians would spend one day a week over four years working towards a City and Guilds’ qualification. At this time the occupation was mostly hands on with little theoretical work. Many started young by today’s standards (starting at 14 years old was not uncommon), and they continued to study well past diploma level. Changing the nature of the role so much that nowadays almost all technical officers have primary degrees and come with a more academic view of the position.

In 2008, it was agreed that incoming technical officers must hold at least a primary degree in order to work at Trinity College Dublin. Those looking for promotion to Senior TO would require a Master’s and to CTO, a PhD. Those already in the system would not be penalised, local knowledge and experience are recognised equivalents and rightly so. This agreement gave rise to the job title changing from technician to technical officer reflecting the removal of the apprenticeship system. Many still use the old name but it doesn’t cause offence. These qualifications represent minimum requirements. TOs constantly train, learning new technologies and procedures. It is difficult to resist the temptation of further study when you work in an educational environment.

From graduate to TO

Gaining experience in medical, industrial, or other educational laboratories is most important. Further study in areas general to laboratory work are also advantageous e.g. first aid, web design, or statistics. Sometimes researchers move into a technical role temporarily and find they enjoy it so stay on. Applying to a discipline with some relationship to your qualifications makes sense; a physicist may not enjoy working in a biological lab. Having come though the university system many graduates would be familiar with teaching laboratories and their departments. Seeing a place for yourself in the future of a discipline is vital for career progression as it is seldom you will see a TO moving from one department to another. It should be possible to adapt the role to your skills or study to meet those required for promotion.

OLYMPUS DIGITAL CAMERA — BioLab Teaching Facilities

Day to day

All labs/disciplines differ but certain core responsibilities fall to the technical staff at some point. Running practicals is the biggest responsibility during term time with design and development out of term. Some departments in science and engineering have lab and field based classes. Various modules require field sampling in preparation for the practical. Getting out on the road can be very satisfying even if you are at the mercy of nature!

If you consider what it takes to run a home you’ll have an idea of what a TO does to maintain a lab/department. Ordering supplies and equipment. When something breaks, repair it or have it mended in a cost effective way. Logging, maintaining and installing equipment, health and safety information and implementation, chemical stock control, running outreach programmes, planning and managing building refurbishment, organising social events, updating the discipline’s web pages, assisting undergraduate student projects and much more.

These are just the basic duties and do not describe the essence of technical work at university level. Firstly it is to guide, instruct, and assist in scientific matters. An analytical and practical mind is necessary. You must have a willingness to facilitate the design and execution of projects in teaching and research. If you are eager to help and learn, it’s the perfect job for you. The information base for many materials and methods is the technical staff. Local knowledge and an ability work in consultation with other departments is often key to completing a project. Ideally, when a researcher leaves the university, their skills should pass to a TO keeping those abilities in-house. Imparting them to the next generation.

If you’re very lucky, you’ll be in a discipline that encourages you to take part in research and further study. It’s wise to check where a discipline or school stands before considering work in that area. Career opportunities open up in such disciplines. CTO Specialist is a promotion given to someone with expertise of a specialist nature e.g. IT, histology. Experimental Officer is a post created to further research in a discipline and often requires some teaching.

Overall, the position is what you make of it. If you strive to improve and adapt, you’ll find it immensely rewarding. Many practical classes repeat annually but on a daily basis you could be doing anything, anywhere. Being a technical officer is stimulating and constantly changing, keeping your brain and body active. You won’t be sitting for too long when you’re surrounded by young adults in need of advice and equipment. The relationship is symbiotic, your knowledge and their enthusiasm eventually gets any problem sorted.

The up-goer five: Explaining research using the “ten hundred” most used words.

At today’s NERD club, we tried our hand at explain our research using the up-goer five, which limited our available vocabulary to the “ten-hundred” most common words (thousand isn’t one of them).

After some brief hesitation, the 9 of us present found out that despite being quite challenging, this can be an incredibly fun and useful activity when it comes to explaining our often jargon-filled research to the public. While this system is rigid, and a tad extreme with words such as “plant” and “science” unavailable, it forced us to find alternative ways of explaining what we do.

Here’s what we came up with:

Original version

Decision makers and land managers are increasingly required to manage landscapes for multiple purposes and benefits. However, despite progress in the development of frameworks linking natural capital to the provision of ecosystem services and human benefits there remains little guidance for how management interventions can improve ecosystem service provision. As ecosystem services cannot be directly influenced, interventions need to be directed towards natural capital stocks. We provide a framework that explicitly links natural capital stocks to ecosystem service provision and identify manageable attributes of natural capital stocks as the critical intervention point. A structured decision making process based on our framing of the ecosystem services concept can facilitate its application on the ground.

How to manage the living things that help us to live and enjoy life
People need many different things like food and wood from the land and I am interested in helping them to manage their land to get lots of good things from it. People have come up with ways of finding out the relationship between living things and the good things like food but it is still hard to find out how to manage the land for what we want. This is because when we make living things different it is hard to tell what will happen to the good things we want. We think the best way of getting out of this problem is to understand how changing where living things are and how many of them there are changes the food and other good things that we want. We help by giving people a plan for how to manage living things that will give us more of the good things we want from the land. This plan will help people to talk about what they want from the land and how to get it.

Olive Heffernan

The world is getting warmer, much warmer and quickly. It’s hot outside, in the air and in the water, even deep down in the water. Ice is becoming water, land is getting drier, so in some places its too wet and in others its too dry. People are having a bad time in lots of places. Animals are sad too. We know all of this because of the hard work of people’s brains.

What can be done?

We can drive less. We can eat fewer moving, living things. We can wear more clothes and not make our houses hot. Or we can do nothing. And wait until it is much hotter. Then we can try to change the world by putting things in space that will block the sun out. Or we can put stuff in the sky to make it cooler. If we do none of these things we might end up in the water, in hot, hot water.

Dr Kevin Healy

Two legged animal eating animals were around for 160,000,000 years but are not anymore. We do not really know what they ate. Some were as small as a dog while others were as big as a bus so they would have needed more food. One type of food that they might have eaten was already dead food. We know animals today eat food they found that was already dead so animals that are not around may have also eaten dead food. But did the big animals that are no longer around eat more or less dead food than the small animals? We made computers games to show that actually both big and small animals are very bad at eating dead things, while animals in the middle are much better at eating dead things. This was true even if we changed how far they could see, how much dead food was there, how many other animal eating animals were around and how much food they needed. We show that dead things might have been important to animals no longer around and that how big you are might still be important to how much dead stuff animals eat both today and in the past.

Luca Coscieme

“If I have everything I need, to do whatever I need to, I am happy. Just to say, if I have food I eat and I am happy. If I don’t have enough I have to eat less, or take food from somewhere else. If I take it from somewhere else, maybe another person will not have it for his own.

To do food I need land. The problem is that after I use land to do food this land gets bad and is not beautiful anymore. But if I have a lot of money, I can buy land and food from somewhere else and keep my land beautiful and clean.

If people can buy the land and the food they need, there can be a person with more money than you that buys all the things you need, and you can’t eat and live. So, it is important to control what people do with their money. It is important to check that no one is taking food or using land that is needed for another person to live.

People with no food get angry and one day they will come where people with money live and take back their land and their food.

I am studying a way to control if people with money is taking food and land from other persons that really need it (more than these people with money).

We can stop that by checking if these people really need these things and if they can find these things where they live. If they can, they have to use them, instead of going somewhere else to make less beautiful the land of other people.

Mean animals that live in other animals and how they make the other animals do weird things when its hot

Mean animals that live in other animals and then hurt the other animals are in many places. The animals I study all live in water that does not run. The mean animals sometimes make the house animals do things they would not do most of the time. When the house animals do strange things, this can make everyone else in the whole water group do things different to how they usually do and power from food can go to different places. When the water gets hot, everyone in the water does things not how they do them in cold water. I study how the mean animals and the house animals do things when the water is hot and cold and how this makes everyone in the water different. I also study how all the animals doing different things can make the power from food go different places and can change who eats who and how often. I study these things in the water outside and in small water inside.

How large a group of animals is can change how they act. It is important to know how big or small a group of animals are so we can understand how they play with one another and live in their home. Small night time animals with black and white faces are important to study because they get a cold that they can pass on to bigger black and white animals that live in fields eating green stuff to make the white stuff we put in our coffee. We carried out a study of papers that looked at the grouping of small black and white faced animals, how many of them lived together, how big their homes were and how many there were in total. We showed that how many animals there are in an area, changes how they act, their relationships with one another and with other animals that may not be their family or friends. All of this means we can better understand how these animals pass their colds onto one another. We have come up with a group of names that you can use to quickly and easily tell other people many animals there are in an area and how it makes this group different to other groups. We hope that our study will help people who want to save the small black and white animals as well as those people who want to do away with the colds that the animals get in a much better way than they do now.

I want to know how the brain understands what it sees in the world. When we see the world through our eyes, they send this to the brain telling it what they saw. The way the brain understands this is important because when the brain talks to the eyes, the pictures can be slow or might not get to the eyes at all. When this happens in people, they think they have a friend when they do not. They are talking to themselves.

We try to understand how the eyes talk to the brain by making simple games on a computer that make animals play with each other with an angry animal chasing a smaller animal. We set up roads between the cells in the brain and then make the brain bigger to see is the angry animal better at chasing the smaller animal in the computer game.

We try to understand this by looking into the animal brain while it plays around in interesting worlds on the computer. By changing the number of roads in their brains before and after the games, animals change what they catch, we hope to learn more about the brains power to understand these games.

This study will make new games of animal moving by bringing good ideas from old people in white clothes to the field of moving studies. Doing so will allow us to answer simple questions about the relationship between bodies of angry animals and their food and to add for the first time why food matters in such relationships. These relationships explain how animals talk with the world around them, and are at the heart of our entire idea of world.

We study how and why trees and other green living things live and grow where they do. To do this we have to go to where the green living things live and look at them and what other things are living beside them. Green living things need to live in the ground, the ground is different all over the world and some things can live in some places and not others. We try to understand why this is by changing what’s in the ground and seeing what type and how many of each thing continues to live there.

Green things what live in the ground can also change themselves to fit the type of ground, rain or sun they get every day. They can change many things such as how big or small they grow or how thick their leaves are but quite often to make a good change to one part of their body they must also make a bad change to another. We try to understand what causes these changes by looking at one green thing that lives all over the world and seeing what changes are made and where the things with those changes are living.

3 years as a PhD student

I arrived in Ireland October 2012 with the purpose of undertaking a PhD supervised by Natalie Cooper on Primates evolution. Looking back, the start of the whole endeavour seemed really stressful to me (new country, new customs, new language) and the project just as frightening (what do I do?, where do I start?, will I be able to do it?)… What happened after was way below my expectations: these three years were anything but stressful and frightening!

OK, even though not everything went smoothly and it had to take the best of the personalities (that are thankfully common sights in Trinity College’s Zoology Department) for dealing with some ups and downs, here is my top 5 list of personal thoughts that always improved the two aspects of my PhD: the working aspect (the research) and the “social” aspect (feeling relaxed and enjoying it).

Be ready to change your PhD

As I mentioned in the first line, my PhD was supposed to be on Primates evolution. In the end, the world “Primates” is mentioned only once (and that is, buried in a sentence about several other mammalian orders). Of course, sometimes the PhD is a Long Quiet River if everything goes well and you keep your highest interest in the original topic. However, sometimes it changes completely! And this should never be a problem! The PhD should be allowed to evolve just as much as yourself (or more pragmatically: your field) evolves into these three or four years.

Failure happens to everyone

Another major part about the PhD (and about the scientific endeavour itself!) is that it will fail. More or less often and more or less dramatically in each case but failure should just be part of the process. As a early career researcher, you can learn a lot from the mistakes and the success of others. However, I found that there is nothing much more personally instructing than the trial and error. I already mentioned how my biggest PhD disaster led to my most positive development.

Stay open-minded and curious

Writing the thesis or even just doing the lab/computer work for the PhD can narrow your mind and highly decrease your sanity. I found that the best way to avoid that was to try as much as possible to make the PhD only priority number two and put all the other things (seminars, meeting speakers, chatting/helping colleagues, etc…) before it. It has two advantages for the PhD: (1) you don’t work on it 24/7 and (2) everything you learn outside of it will actually be super useful for the PhD. In the Zoology Derpartment, we were only a couple of people doing macroevolution surrounded by ecologists. Yet, I think my work benefited heavily from the influence from these people.

Don’t rush

One thing I found nice with the PhD is that before you even start – before day one! – you already know the final deadline. OK, at day one, the handing in date seems far away (3 or 4 years away actually!) but that leaves you plenty of time for doing awesome research, writing it down as papers/chapters (and even trying to publish them before the deadline) and going to the pub or to other non-PhD recreational events…

Chat with your colleagues

Finally, I found that I gained so much just by chatting with my colleagues. And by colleagues I mean my fellow PhD students of course but also with the post-docs and the staff. I always found a long term benefit to both PhD aspects, whether it was talking about the latests video games during working time (I’m not only looking at you @yodacomplex) or having heated debates about species selection during coffee time.

I know much of these tips worked for me but might not apply to other people. In the end their is only one ultimate tip: make your PhD a hell of a good time!

A Nobel Pursuit

Splitting the atom, unlocking the secrets of radiation, or even leading a peaceful civil rights movement.

I grew up knowing that these were the sorts of achievements that earn you a gold medal and an invitation to Sweden in mid-December. I have since learned that the annual ceremony held in honour of Alfred Nobel hasn’t always been awarded to the most deserving candidate, and that sometimes the winners simply stumbled upon a discovery that changed the world. This was not the case with the 2015 Nobel prize for Physiology and Medicine. Continue reading “A Nobel Pursuit”

Career planning for PhD students

The Royal Society has published a new set of guidelines for managing the career expectations of PhD students in STEMM subjects (science, engineering, technology, maths and medicine). The publication was the result of a series of roundtable discussions held at the Royal Society with PhD students, supervisory teams and University careers professionals.

This blog post from the British Ecological Society provides a good overview of the document and discussion of how it fits into existing career development opportunities for PhD students.

With ever increasing numbers of PhD graduates and restricted academic jobs, academic careers are becoming the exception rather than the rule in many STEMM disciplines. The report highlights the need for PhD students to be realistic about their career expectations and goals and the importance of continuous professional development during their studies.

The document contains guidelines and recommendations for students, supervisors, career professionals and higher education institutions. It’s very encouraging to see that the training and mentoring of ecology and evolutionary graduate students at TCD already follows many of the principles.

This is mainly due to the success of NERD club, our weekly meeting of ecology and evolution researchers. The primary purpose of this group is to develop research projects and encourage new collaborations but many sessions are also devoted to career development. We have discussed academic careers advice and application tips but also non-academic careers and the transferrable skills such as public communication and teaching that can be applied to any career choice. As students, we’re very lucky to benefit from the mentoring and advice of enthusiastic and dedicated staff members.

One aspect of the Royal Society guidelines which I hadn’t considered previously is the recommendation that PhD students should seek a mentor who is not their supervisor for career advice. It’s an interesting suggestion, especially since many supervisors have limited personal experience of non-academic careers, and a good thing to consider for any PhD student.

Hopefully these new guidelines will encourage more students, supervisors and institutions to make broad career planning an integral part of every PhD student’s experience.

Un-reclaiming the name – I am not a zoologist

[Disclaimer – this is just my opinion. I do not speak for everyone at EcoEvo@TCD]

Recently on Twitter there has been a call to “reclaim the name” of Botany accompanied with the hashtag: #iamabotanist. The response has been really cool – lots of different scientists working on different questions have posted pictures of themselves on Twitter, often with their plants. It’s amazing the diversity of researchers out there who identify as botanists.

But why try to reclaim the name Botany? The issue is that Botany as a discipline is seen as rather old-school and irrelevant to current scientific challenges. For these reasons it tends to be unpopular with undergraduates and also with university governing boards. More and more Botany departments are being closed or merged with other departments, and Botany courses are being revamped and renamed to attract more students. Zoology departments are suffering similar fates. Like Botany, Zoology is considered an outdated discipline. It tends to fare better with undergraduate students because there are always people who want to work in a zoo or think they might get to cuddle a panda!

I appreciate what the #iamabotanist campaign was trying to do, but I’m not sure I agree. I work in a Zoology department, but I am not a Zoologist. This isn’t because I think Zoology is irrelevant as a discipline, it’s because I’m far more interested in the questions I’m asking, than in the taxa I use to test my hypotheses. Yes, the mammals I work on are adorable and fascinating, but what drives me as a scientist is trying to understand their evolution and ecology, and how the two things are connected. I’ve mostly worked on mammals so technically I’m a mammalogist. I’m happy with this label, but it’s not what I’d call myself if anyone asked. I’d identify as an (macro)evolutionary biologist, or an evolutionary ecologist. I test my ideas on mammals because these are the group I have most data for, but I’m equally fascinated by insects, bacteria, epiphytic plants, parasitic helminths etc. I think we do a disservice to the science if we focus too much on one taxonomic group.

Zoology and Botany at Trinity are particularly diverse disciplines. We have a couple of “classical” taxonomists/systematists, but also phylogeneticists, landscape ecologists, behavioural ecologists, demographers, evolutionary biologists, conservation biologists, developmental biologists and parasitologists. We teach courses across discipline boundaries, and often the person doing research closest to our own is in the other department. But sadly the Botany-Zoology divide still exists, mostly for reasons of history and geography (we are in separate buildings). This is holding back science, rather than pushing it forward.

Maybe we need to identify as botanists or zoologists (or any other taxon specific -ologists) less often, rather than more often. Forcing general questions and principles down taxon-specific lines seems rather backwards. It also isn’t helpful to our students if they only learn about animals and not the plants they eat, or only learn about plants and not the animals they are being eaten by. This interconnectedness is particularly important in light of the challenges of global change and the current extinction crisis.

So in conclusion, I think animals are cool, but I’m not a zoologist.
