Home and Away: Monotreme mistakes

Natural history museum collections are invaluable snapshots of history. Research collections can be used to trace how animals have changed over time. Collections are also a reflection of the people and attitudes at the time it was curated. There is a well-represented collection of native Australian animals in the Zoology Museum at Trinity College Dublin. Well-represented in many sense of the word. This is a story about the red land down under, Australia, and the collection of Australian animals held in overseas museums around the world. It is a story in parts. This is the second part. Read the first part here.

Monotreme Mistakes

Echidnas (Tachyglossus aculeatus) are monotremes; Order Monotremata within Class Mammalia. They have hair and produce milk like other mammals but unlike other mammals, they lay eggs. Monotremes are endemic to Australia and New Guinea and consist of the four species of echidna and the platypus (Ornithorhynchus anatinus).

EcoEvo Blog Photo competition winner announcement!

Once again, the time has come for the annual Eco Evo photo competition! The third instalment of the competition saw some wonderful submissions from across the School of Natural Sciences, and the top spot was fiercely contested. Due to their desire to participate, the editors stepped away from the judging process and the shortlisting was conducted by an unbiased third-party and the photos were anonymised. Finally, the vote for the winning photo was put to the Trinity School of Natural Science, again the photos were anonymised.

Read on to see the full gallery of submissions and to find out which photo was chosen as the winner.

Home and Away: Would a Rosella by any other name smell as sweet?

Natural history museum collections are invaluable snapshots of history. Research collections are snapshots of the animals and plants collected in history. Research collections are also a reflection of the people and attitudes at the time it was curated. There is a well-represented collection of native Australian animals in the Zoology Museum at Trinity College Dublin. Well-represented in many sense of the word. This is a story about the red land down under, Australia, the collection of Australian animals held in overseas museums around the world. It is a story in parts. This is the first part.

This story traces its roots to the day that Europeans invaded Australia, but we will start with the Saturday the 26th October 2019. For most of the world, Saturday was not a particularly notable day. It was the beginning of the Bank Holiday long weekend here in Ireland; I enjoyed a walkabout through the local park. But as the sun dawned on Uluru in the Northern Territories, Australia, it was the start of a historic day.

Meet the new editorial team for 2019/20!

Time flies and it’s time for yet another academic year! We’re a bit late for our introduction, students are already heading into reading week but we were too busy getting over the shock that first years were born in 2001… Do you feel old too?

And with that, we wave goodbye to our fantastic 2018-19 editor, Fionn Ó Marcaigh. Thank you for your hard work and enthusiasm for sharing people’s stories! We have big shoes to fill… We say “we” because this year, you get two editors for the price of one! Let us introduce ourselves:

Fieldwork, and why students need it

I recently took part in the 3rd year Terrestrial Ecology field course in Glendalough. Though I already had some experience teaching both lab work and fieldwork, this was my first time being “staff” on a trip I had previously been on as a student. It was a wonderful experience. This field course is a venerable institution of the Zoology Department: it has taken place Glendalough every year since 2007, having previously been held in the Burren and Killarney National Park. It has always been beloved by students, as seen in this video made in 2016.

Zoology students in Trinity have the chance to take part in three field courses: Terrestrial Ecology in Glendalough, Marine Biology on the rich shores of Strangford Lough, and Tropical Ecology around the ancient Rift Valley Lakes of Kenya. Here, from enthusiastic and experienced teachers, they learn skills that will stand to them in any ecological undertaking. On the Glendalough field course, students of both Zoology and Environmental Science are introduced to the techniques used to sample and survey wild animals, including Longworth trapping for small mammals, malaise trapping for flying insects, kick-sampling for aquatic invertebrates, and mist netting for birds. This last one was what brought me on the course.

Undergrad Thesis Collection 2019

Every year, the Trinity College Dublin Zoology, Botany, and Environmental Science moderatorship students (final year undergraduates) complete their own research projects related to their course. It has been my absolute privilege to spend time with these talented students and to watch their projects take shape. I am blown away by the dedication they show, the incredible topics they cover, and the way in which they approach their investigations. After their theses are submitted, the students hold a poster session where they present their work. From beetles to beer and back again, this year’s students have done impressive and solid work. I hope all our readers enjoy learning about these projects as much as I did! If you’d like to contact any of these students to congratulate them, offer them prizes/jobs, or learn more about their projects, most of them have included contact information. Without further ado, I’ll let them take it away!

Medieval Zoology

Ever since the observations of Aristotle, said to be the earliest works of Western biology, we have endeavoured to understand the workings of the natural world. But the modern scientific method is a relative latecomer on this scene, and it is fascinating and humbling to see the many creative ways in which we have managed to get it wrong over the years. Modern zoology, ancient zoology, and medieval zoology are all part of the same weird and wonderful phylogenetic tree.

Before there were peer-reviewed journals, there were bestiaries, medieval books that described the world’s animals as Europeans of the time understood them. Before there were Zoology Departments, zoologists (or the closest thing that existed at the time) would put forth ideas that seem ridiculous today. Three of their best theories are collected below.

Un-reclaiming the name – I am not a zoologist

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.

What’s it like to study Zoology?

ZooEntrance

Tell someone on the street that you study Zoology and you can pretty much guarantee what their follow up question will be; “so you want to work in the zoo?” Well not quite. Of course some zoology graduates conform to the general stereotypes; the zookeepers, conservation managers and wildlife handlers who keep the rest of us supplied with a steady stream of tales of adventurous exploits and envy-inducing pictures on Facebook. But that is only one side of what you can do as a zoologist. It’s not all about frolicking with cute animals. There’s a healthy dose of molecular and lab-based research, theoretical studies and unavoidable number crunching which make up significant portions of life as a zoologist. Not to mention the diverse career opportunities, in areas such as science communication, education, policy and management, that are available to zoologists who venture beyond traditional research jobs.

A group of Transition Year students (15/16 year olds) recently spent a week in the department learning about what it’s like to study and work as a zoologist. Some of their questions and misconceptions prompted me to write this blog. Consider it the lowdown on zoological life if you will.

Zoology is not just about cute animals

If your interest in zoology stems from a desire to spend your days playing with puppies or equivalent bundles of cuteness then be warned. Such opportunities do arise during a degree course but they are relatively limited. You will spend more time in lecture rooms, dissecting dead animals or behind a computer than you will interacting with live animals. Of course field courses, summer research opportunities and final year undergraduate projects do offer many opportunities for hands-on, practical experience but these are the exceptions rather than the rule for life as an undergraduate zoologist. Post-graduation is another story entirely: there’s puppies, meerkats, elephants and dolphins aplenty if that’s what you want!

Zoology is not stamp collecting

Modern zoology stems from the long scientific traditions of enthusiastic naturalists: the genteel country gentlemen who wiled away the hours with contemplations of beetles and the exotic explorers who bravely ventured forth into unknown lands. These origins have created a common misconception that modern zoology follows the same veins; we may collect DNA sequences rather than butterflies now but surely it’s all just descriptive stamp-collecting at heart? Well, no. The methods and techniques used in zoology research are just as scientifically rigorous and complex as the “machines that go ping” which grace any physics or chemistry lab. Zoology is no more exempt from number crunching and computational methods than any other scientific discipline. You don’t have to be a maths whizz or computer nerd but a career in zoology, no matter what branch, will inevitably involve quantitative and not just qualitative analyses.

(Most) Zoologists are not hippy dippy animal lovers

A common misconception about being a zoologist is that it’s a just a fancier term for people who are only concerned with animal rights and issues. So we should all be strict vegans who spend our holidays trying to board Japanese whaling ships and we would rather halt economic progress than lose a single species of ant to extinction. Inevitably there is an element of truth to these ideas. We chose to study zoology because we’re fascinated by the natural world and the logical progression of such interests is a desire to protect and conserve all aspects of life on our planet. But our pro-animal tendencies don’t equate to making us anti-human!  Zoology teaches us to develop and apply appropriate, practical and realistic management and conservation actions to protect biodiversity while also enhancing human economic and social livelihoods.

Zoologists don’t just do field work

I chose to study science generally and zoology more specifically because I was adamant that I didn’t want to be stuck at a desk in an office. Guess where I spend most of my days now? Zoology isn’t all about trekking through jungles or diving on ocean reefs. Most research zoologists spend the majority of their time indoors whether that’s at the lab bench or behind a desk. The difference lies in the fact that, unlike a “normal” desk job, zoology provides plenty of opportunities to get out of the office whether that’s catching vultures in Swaziland, perusing museum collections, island hopping in Indonesia or traveling the world for conferences.  These are the undoubted highlights of any research project but they represent the cream of zoological life: usually you will spend far more time working at your computer than exploring the outside world.

Zoology is…great!

Don’t be fooled by the apparent negativity of the points above. I love studying zoology. I love the diversity of the subject, the breadth of knowledge to which we are exposed, the fascinating research questions we study and our undeniably awesome opportunities to travel.  I fell into zoology by accident rather than design and I could not be happier with my choice of subject. Research careers in zoology are varied and exciting but a zoology degree is also great preparation for so many opportunities beyond the realms of traditional research. Zoology is suited to people who are interested in nature, the environment, biology in general or anyone who is a confirmed lifelong disciple of Sir David. Zoologists are well equipped to take up any variety of career paths.

Our horizons both include and extend beyond the zoo gates!
