23rd October 2017 – Alyson Brokaw, Texas A&M University

Alyson BrokawI am a third year PhD student in the Ecology and Evolutionary Biology Doctoral Degree Program at Texas A&M University. Broadly, I am interested in sensory ecology and animal communication, with a focus on bats. As a diverse group with over 1300 species, bats are a great system to investigate a range of ecological and evolutionary questions. It doesn’t hurt that they are also cute (#TeamBat)!

 I work in the Smotherman lab, where we study the ecology and neurobiology of bats (www.smothermanbatlab.com). Recent work in the lab has focused on singing and communication signals in Mexican free-tailed bats, networking strategies in groups of bats, neurological and muscular control of bat ecology, and territoriality and singing behavior in African bats. For my dissertation I am exploring how bats use olfaction for foraging, communication and navigation. I plan to address these topics using a combination of neurophysiology, histology, lab and field based behavioral experiments.

 I got my start in field ecology research as an undergraduate student at Cornell University, working with tree swallows in the Winkler lab. I also have a Master’s degree from Humboldt State University, where I studied the communication signals in Yuma myotis (a common small brown bat found in the western United States). I have been involved in field work on swallows in Argentina, cuckoos in Arizona, coyote and kit fox in Utah, migratory tree bats in California and leaf-nosed bats in Mexico.

 As a bonus, I am hosting Biotweeps at the same time as Bat Week (batweek.org), so expect lots of discussions about bat ecology, evolution and conservation, with as well as a mix of personal experience, outreach, #scicomm and #phdlife.

16th October 2017 – Liz Martin-Silverstone, University of Southampton and University of Bristol

Liz Martin-Silverstone.pngHi all! I’m Liz Martin-Silverstone, and I recently completed my PhD in palaeontology at the University of Southampton (but also associated with the University of Bristol) in the UK. My research is based on biomechanics and mass estimation in pterosaurs, the extinct flying reptiles that lived alongside dinosaurs (but are not actually dinosaurs!). I’m currently looking for post-doc positions, and working as a research assistant on a project involving zebrafish for a few months in the meantime.

I completed my BSc in palaeontology at home at the University of Alberta in Canada, where I became fascinated with pterosaurs, and got my first bit of research experience. I then decided to move to the UK and pursue grad school, doing my MSc in Palaeobiology at the University of Bristol, where I began working on pterosaur bone mass. Fortunately, my MSc project led into a PhD project, and I moved to Southampton to continue this work. I’m currently more interested in the evolution of the air sac system in birds and pterosaurs, and would like to work on this in the future. I’m a big scicomm fan (otherwise I wouldn’t be doing this!), and currently help produce a podcast called Palaeocast, and also volunteer with a Canadian science blogging community called Science Borealis.

My week at Biotweeps is going to focus a bit on my own research, palaeontology in general (I’ll try to dispel some of those common palaeo myths), and a bit about what I’m doing now both in terms of research and scicomm. I’d also like to talk a bit about some of the issues I had to overcome as a PhD student, such as funding and university-related issues, and how these things can affect students.

28th August 2017- Julie Blommaert, University of Innsbruck

Julie BlommaertHi Biotweeps!

I’m Julie (@Julie_B92) and I’m really looking forward to hosting biotweeps and chatting to all of you this week about my interests and research!

My research interests all focus around evolution and genetics. I guess I should start with a little background about how I got to be interested in these topics. Growing up, I wanted to be a vet, but then a few life things pushed me away from vet school, and for a while I didn’t know which direction I’d like to go in, other than not-vet. I considered being a pilot, and was even lucky enough to be gifted a test flight for my 16th birthday, but decided that, even though flying is fun, I didn’t think I’d like it as a job. I still hope to get my private pilot’s licence though! A few months later, we started to focus on genetics in my biology classes, and I was hooked!

Fast-forward a few years, and I found myself at the University of Otago, doing my BSc majoring in Genetics. We had so many chances to do different lab projects and experiments, and I found my interests in EvoDevo (Evolutionary developmental biology- the field that compares how different species develop to get a deeper understanding of how different forms evolved). So that’s what I did my honours project in, looking at some genes that control early development in a weird animal called a rotifer (a tiny, cute zooplankton). I had some further adventures in EvoDevo, but I’m now doing my PhD in evolutionary genomics.

My PhD project focuses on the evolution of genome size in, coincidentally, the same species of rotifer that I worked with for my honours project! So, what is genome size and why do we care? Genome size refers to the amount of DNA per cell of any species. Usually, different individuals of the same species have the same amount of DNA per cell as each other, but not my rotifers! Within the same species, their genome size can vary by up to 30%, which is really weird. But again, why do we care? Genome size varies a lot across the whole tree of life, and there are lots of debates about why this might be. Lots of people have tried to make comparisons to figure out why this might be, but often, there have been other things that get in the way of comparing genome sizes because the species being compared were so different. So, hopefully, we can study genome size change in a single species and learn a bit more about why genome size changes, and why some genomes (including our own), seem to be mostly “junk”.

Other than my PhD work, I really like spending time outdoors; climbing, hiking, relaxing in the sun, and I also play for my local canoe polo team.

I’ll talk more about my work and hobbies through the week, I hope you’re as excited about this week as I am!

7th August 2017 – Shandiya Balasubramaniam, Museums Victoria

Shandiya BalasubramaniamHi Biotweeps!

I’m an evolutionary ecologist working on avian systems. In a nutshell, I like to know what birds do, and why, where, and how they do it.

I completed a PhD at the University of Melbourne on the evolution and ecology of major histocompatibility complex (MHC) genes in south-eastern Australian passerines (songbirds). MHC genes are a vital component of the vertebrate immune system, and I wanted to know more about the evolutionary processes underpinning variation in these genes. I was also interested in how MHC variation was influenced by ecological variables, such as dispersal behaviour and habitat configuration. To answer these questions, I mist-netted over a thousand birds across two years, resulting in a love/hate relationship with early mornings. Somewhere along the winding PhD journey I developed an interest in wildlife disease, and ended up doing a survey of avian malaria in woodland birds as well.

I’m currently a research fellow at Museums Victoria in Australia, where I’m working on a few different projects. My main focus at the moment is on the ecological ramifications of beak and feather disease virus (BFDV) on threatened parrots. BFDV is thought to be infectious to all parrots, but can it also infect other birds? And if so, what does that mean for the transmission of BFDV across species? If you’re interested in knowing more about any of my research, get in contact!

When I’m not science-ing, I’m either baking bread or accumulating cats. I can be found on Twitter @ShandiyaB.

29th May 2017 – Rutger Vos, Naturalis Biodiversity Center

Rutger VosMy name is Rutger Vos, and I am computational evolutionary biologist at the natural history museum of the Netherlands, Naturalis. My educational background is in evolutionary biology, most especially in phylogenetics, i.e. the field of biology that concerns itself with researching the Tree of Life. For my PhD research, it became clear that I needed to handle amounts of tree and alignment data that were unmanageable to do ‘by hand’ on a normal computer, so I taught myself programming and how to use high-performance computing systems.
One thing led to another and I ended up doing my postdocs as a contributor to various infrastructures having to do with phylogenetics, most notably the CIPRES (http://www.phylo.org) project and TreeBASE (http://www.treebase.org) – but also projects having to do with data standards and data sharing in biology. ‘Open Science’, basically.
Meanwhile, the high-throughput DNA sequencing (NGS) revolution was starting to spit out more and more genomes, with which I started to play around. So much so that by the time Naturalis started looking for a bioinformatician to contribute to the NGS projects that were going on over there I could plausibly apply for a position.
At Naturalis I’ve become involved in a lot of different projects, all of which have bioinformatics or computational biology in common but are otherwise very broad-ranging. I’ve had the good fortune to be able to work with many of the kinds of data, information and knowledge that circulate in a natural history museum. For example, apart from DNA I’m also analyzing image data from our specimen digitization efforts, scanned texts, and species traits and distributions.
On Twitter (@rvosa) I let out my interest in ‘unnatural history’. It’s a totally vague term that I’ve adopted to look at and talk about the cultural ways in which we interact with nature. I mean things like art about nature; the way we, biologists, do science about nature; how we as a species are colliding with biodiversity because of our actions. By the way, I later found out there’s also a book called ‘Unnatural History’. I haven’t read it but it looks neat and it looks like it’s partly about the same topic.

22nd May 2017 – Seth Barribeau, University of Liverpool

I’m an evolutionary ecologist who largely works on understanding how insects are able to do complicated things with what is generally considered a ‘simple’ immune system. Spoiler: it’s not that simple. I am fond of most animals, with the noticeable exceptions of ostriches (they have cruel, dead, eyes) and locusts (a childhood incident). I started out studying the what predisposes tadpoles to infection as a graduate student in New Zealand, and after a brief stint catching snakes, teaching English, and proof reading medical articles in Japan, moved on to studying aphids and fungus-growing ants at Emory University, and then bumblebees at the ETH in Zürich. After studying and postdoc-ing in several countries I recently started a position as the lecturer for eco-immunology at the Institute of Integrative Biology at the University of Liverpool.
My recent research has explored why aphids have a pretty rubbish immune system, why the costs of mounting an immune response differ among individuals, how diet influences the expression of immunity, how bumblebees respond differently to different genotypes of a common parasite, what makes immune memory, what does sociality do to the evolution of the immune system, and, most importantly, was Marvin Gaye right? Is there such a thing as sexual healing?

24th April 2017 – Danielle Gilroy, Operation Wallacea

Danielle GilroyI am a terrestrial research and operations officer at Operation Wallacea, based in the UK with offices worldwide, and carrying out conservation research in 15 different countries. I oversee of all the forest-based research and am also the Senior Scientist for our largest forest site, Cusuco National Park in Honduras. My main research interests are centred in evolutionary biology and using a combination of molecular and ecological tools to investigate how evolution shapes diversity in populations. I have always strived to carry out research with real conservation applications and I am helping Operation Wallacea’s sister charity, the Operation Wallacea Trust, to make use of our large spatial and temporal datasets from sites around the world to lever funds to best establish conservation practice and work towards protecting particularly vulnerable and highly biodiverse ecosystems.

My PhD at the University of East Anglia focussed on a particular conservation success story, the Seychelles warbler (Acrocephalus sechellensis). This endemic island passerine was once down to just 25 individuals on a single island in the Seychelles archipelago in the 1980s, but has since recovered due to a combination of science research integrated with effective island management. There are now over 3000 birds across five islands, 115 times what it was over three decades ago and importantly, we have learnt a lot by using this species as a model of evolutionary study. My thesis looked at the causes and consequences of functional variation within the bottlenecked source population of Seychelles warbler. I investigated how variation at genes critical in innate immune defence could influence individual fitness and a bird’s ability to fight disease, mainly avian malaria, and considered the long-term viability of the species by assessing its genetic health and predicting future changes under natural selection.

During my week, I will focus on our work at Operation Wallacea and present to you our ongoing conservation research across our many terrestrial and marine sites. I will also talk about the importance of molecular ecology as a relatively new and quickly-growing field and as an ornithologist, will no doubt mention birds at every opportunity I can. On a similar note, I will no doubt mention my rescue staffy dog Tia who often accompanies me on my birding adventures.
