Evading Extinction

The black footed ferret

It’s a sombre statistic: year on year, we lose up to 100,000 species. That’s somewhere between 0.01 and 0.1 percent of all species on the planet (we don’t know the exact rate because we don’t know exactly how many species exist; it could be 2 million or 100 million). The rate is thought to be at least 1000 times what it would be in the absence of the deforestation, poaching and pollution we are responsible for.

 

But despite this gloomy outlook, prospects are improving for some species that have narrowly escaped extinction. That’s partly thanks to ongoing success in breeding species that are extinct in the wild, and reintroducing them.

 

I’m Olive Heffernan, a freelance science writer who covers the environment for outlets such as New Scientist, Nature, Nature Climate Change (of which I’m the former Chief Editor) and Scientific American. I’m also currently Science Writer in Residence in TCD’s School of Natural Sciences. While I’m here, I’ll be blogging from time to time about the topics I’m reporting and writing on.

 

My latest article, published in New Scientist, reports on the animals that are scrambling back from the brink of extinction. Some, such as the black-footed ferret, were once presumed extinct in the wild.

 

The ferret’s story is an interesting one. Once native to the North American Prairies, these cute nocturnal creatures were essentially wiped out by the arrival of European settlers in the 1860s. As they began to cultivate the plains and to breed cattle, the farmers started to poison prairie dogs – the ferrets’ favoured food – because they worried that their cattle would break their legs by stepping in the burrows. What’s more, ferrets were especially susceptible to plague brought to the US during the early 1900s on trading ships from the Far East. By the late 1950s, the ferret seemed a distant memory and by the late 1970s it was considered extinct.

 

But in 1981, a working dog on a farm in Wyoming brought home a surprising kill – a black-footed ferret! The US Fish and Wildlife Service subsequently recovered 18 live ferrets and eventually – after a few failed attempts – they bred some in captivity and reintroduced ferrets into the native habitat. By 2008, the wild population had reached around 1000 individuals again, but from 2008 to 2015, the number of breeding adults declined by 40%, due to plague.

 

Thanks to sustained efforts by US Fish and Wildlife, together with the World Wildlife Fund and Defenders of Wildlife, 300 individuals exist successfully at 6 sites on public and private lands from Mexico to Canada. The goal is to establish 3,000 breeding adults throughout their former range, at 30 different sites.

 

The main challenge will be keeping the ferret populations plague-free. The ferret’s story is a good example of how conservation efforts are often a long, hard slog over many decades. As Mike Hoffmann of the International Union for Conservation of Nature (IUCN) Species Survival Commission, says in my New Scientist story “Success takes many, many years to achieve. And all the major conservation success stories, whether it is the black-footed ferret or Arabian oryx, have taken decades of hard conservation work on the ground and continued effort.”

 

You can read about the recovery of the Scimatar-horned oryx, the blue-eyed black lemur, and a range of other species in my article, which is online here (behind a paywall) and also in the current issue of the print magazine. There’s a very nice photo gallery of species bouncing back from the brink in the online version.

3 years as a PhD student

2015-04-04-14.10.45
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!

The world economy in a cube

 

In 1884, the English theologian and pedagogue Edwin A. Abbott wrote a romance called “Flatland”, in which he described a two dimensional world. The rigid and hierarchically organized society of Flatland develops in the large plane in which it lives, and flat authorities control that no flat citizen (the inhabitants are all flat geometric figures) escapes from the two-dimension reality. The book is a social satire as well as an exploration of the concept of multiple dimensions. Furthermore, it can also be viewed as a critic of narrow worldviews stubbornly based on old paradigms.  

flatland_abbott_edwin_3

The novel’s example can be used to argue that despite the proliferation of metrics, our decision making process tends to be guided by the quasi-imposed limited set of information tools – mainly economic – that we use every day. In other words, concepts like Earth System, Planetary boundaries or biophysical limits, environmental sustainability, social welfare and other important elements of our life on this planet are not satisfactorily incorporated in our knowledge horizon.

The current economic worldview is based on the idea that a free market works for the 100% of the population. Thus, economic growth (as measured by growth in GDP) is the political mantra: “the rising tide that lifts all boats”. A recent study published on Global Environmental Change (available here) gives a different point of view by including the environment and the society in the economic picture.

National economies are investigated in a 3-axis diagram (a cube), where each dimension is a different compartment. In this way, the relationships between environment, society and economy are represented in a single framework without losing the specific information. This framework recognizes a physical (and also thermodynamic, and logical) order, highlighting the dependence of the economy on societal organization and, primarily, on the environment.

From this three-dimensional perspective emerges that the economic activity is always strictly correlated with the use of natural resources, and that social well-being is often neglected. Over a total number of 99 national economies investigated within the cube, none of them is at the same time environmentally sustainable, economically rich (high GDP), and equal in the distribution of income.   

This means that growing GDP is beneficial for a limited fraction of the overall population, while the vast majority has to deal with increasing environmental problems and worsening ecological status. Moreover, decoupling economic growth and natural resources consumption, seeking the so-called dematerialization, is found very complicated. Continuous growth in GDP implies consequences especially for the poorest individuals and communities: “the rising tide is lifting the yachts and swamping the rowboats” (Dietz and O’Neill, 2013).

Politicians are looking at the world around as a mono-dimensional economic universe. This is due to the fact that economists play a relevant role within governments. We need ecologists and social scientists playing an equally relevant role, in order to finally show politics we live in a three-dimensional world.

A Nobel Pursuit

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

80ea0fb0832c7d4c0eabeefe1f7f1b44

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”

Money Walks and Talks in Academia

Buzz_Tweed

As junior academics spend longer in their career, sooner or later, they start to realize that money matters more than anything when it comes to dealing with University Administration. Some will have this formalized in their tenure track agreement, but others will more blindly wander into it as promotion looms, and ask they get involved in developing plans for new hires in their department. Being wiser to this reality earlier on in my career might have helped me make different decisions along the way, or at the very least temper my idealism with a more natural cynicism.

 

For many academics, money (even one’s salary) is a secondary thought to research and teaching.  But obviously, these professional activities require money for them to function and often require substantial amounts for them to be done to a high level. You would be forgiven for thinking that where this money comes from is irrelevant and that its what you do with the money that counts, not just getting it.

 

As part of the economic crash that befell Ireland (and pretty much everywhere) sometime around 2008, the government accelerated is cut-backs to the 3rd level education sector. The latest figures I have heard kicked around my institution is that the government provides directly only about half the amount of money that is required to educate our students. This is an enormous shortfall to make up and doubtless troubles the sleeping patterns of our Provost and his administration greatly. Among the various options to bolster the funds are the usual suspects of international students (though in reality, although their fees are high, the government don’t supplement their place with additional funds, so its not really all that high when the money hits the red line), wealthy donors and of course overheads on research grants.

 

Different countries and institutions administer overheads differently, but generally there is some mechanism by which the university gets a percentage of the grant into a separate account to the research project which they can do as they wish (sometimes with conditions).  In Ireland, these might as much as 30%, but equally could be 0%. These overheads might be split, with some going to the PI that won the grant, some going to support PhD scholarships and some going who knows where in the black hole. Deans like big grants, because they come with big overheads, and this is where the trouble starts.

 

During a meeting to discuss the possible recruitment of a new senior academic in quantitative ecology, I was rebuked for naively pointing out that the person in question would be somewhat immune the current economic as their infrastructure demands were modest.  If you do expensive research, the financial benefits to the institution are larger than if your research involves a few computers for example. Dig up the cricket pitch, knock down the Arts Block and install a particle accelerator and name it after someone wealthy*. This is why disciplines whose research is cheap, and individuals who have low costs, face an uphill battle in gaining attention and reward for their work.

 

Money begets more money too. As well as PIs in receipt of grants receiving a portion of the overheads (not always the case even within my institution), some are then given additional monies from our national funding agency (as is the case for SFI who will give anyone with an Advanced ERC grant moving to Ireland up to €1million to smooth the transition!), but they are also rewarded indirectly with staff appointments in their research area (I suspect mostly as an easy decision that doesn’t need much thought beyond “there’s gold in them there hills”).

 

For my part, the grants I have held to date have not provided overheads of any note and I have benefitted indirectly from the grant successes of others, with my students accessing scholarships, stipend awards and travel expenses (though some of these funds come from philanthropic donations too). The reasons these grants don’t come with overheads are that the funding agencies in question argue that the PhD student fees they pay are there to cover the bench fees and associated costs for the student.

 

The most frustrating part is that all the research and teaching outputs in the world don’t make up for inputs in the form of cold hard euros. A recent internal missive from our institutional Research Office berating us for slipping down the world rankings by a whole 7 places, seemed to forget that many of the members of the academic community who contributed to our top 100 placement through hard-fought teaching and excellent research papers, books and other outputs, did so on a shoestring budget with innovative vim and vigour, in the face of cutbacks to our research, teaching and personal incomes.

 

We should all celebrate with our colleagues when they get the big grants as we all benefit from their success, and we collectively need the money to make the academic world go around. Those who win these grants need to remember that not every can and will be able to land these treasured grants and that they themselves were to some lucky on the day. Those running our institutions** need to remember that the success of any activity will ultimately be valued on its outputs and not who won the most money, even, in the end, university rankings.

 

 

*though I was pleased to read that Trinity recently spurned this approach so as to not turn off the not-quite-so-loaded donors.

 

**Interestingly, our nearest neighbours out at UCD handled their rankings very well, with a balanced and measured message to the community.

Back to School.

Welcome back everyone.

One_Made_it

As the dusts settles on a hectic first couple of weeks, we finally have a chance to welcome everyone back from the much needed summer break (for those who got one).

We started this week with the exciting news that an alumnus of TCD Zoology, Dr William (Bill) Campbell has been awarded the Nobel prize for physiology and medicine with Satoshi Omura “for their discoveries concerning a novel therapy against infections caused by roundworm parasites”. Dr Campbell joins Dr Ernest Walton and Samuel Beckett as graduates of Trinity College Dublin to win the award. Obviously, exciting news such as this deserves its own blog post, so watch this space.

Tuesday brought with it the first Nerd Club of the year, as our research and teaching staff got together to plan the year of workshops, talks and presentations to keep us ticking over until May. As each week will cover different topics of interest to our readers, we’ll endeavour to write short openness to summarise the results of our discussions.

The Michelmas term brings with it the commencement of undergraduate teaching, and we are delighted to welcome back our returning Senior Sophistors, as well as our new crop of Junior Sophs, fresh from their marine field ecology trip to Portaferry.

ZooSoc has hit the ground running for the 42nd session, with dozens of events planned for the coming months under the guidance of Fionn Ó Marcaigh and his dedicated committee. Keep an eye on their Facebook, and twitter for details.

For regular news updates form the department of Zoology, be sure to check out Zoobytes on Facebook.
