Jon began university life as a geologist, following this with a treacherous leap into the life sciences with a course in biodiversity and taxonomy. Now undertaking a PhD in tetrapod biodiversity and extinction at Imperial College London, there was a brief interlude were Jon was sucked into the world of science policy and communication. He blogs at http://blogs.egu.eu/palaeoblog/, tweets as Protohedgehog and co-runs an [infamous, probably] podcast series called Palaeocast. Jon can usually be found procrastinating in pubs, trying to exchange bad science, usually about dinosaurs, in exchange for food and beer.
Tell us a bit about you and your social media project
I’m currently a PhD student at Imperial College London, investigating the biodiversity patterns of tetrapods (anything with four limbs/wings/flippers) about 145 million years ago to see what we can figure out in a macroevolutionary sense, and whether we can find a ‘hidden’ mass extinction in the fossil record. I commit some of my time to 3 major social media platforms: blogging, tweeting, and podcasting, with a bit of Facebook, LinkedIn, Google+ and others on the side. These activities are less of a project, per se, and more just stuff I do in parallel, and often with overlap, with my PhD research.
Dinosaurs. What springs to mind when they’re mentioned? Colossal, towering sauropods? Packs of feisty feathered fiends? Or huge herds of hadrosaurs, chomping their way across the plains of long-lost worlds? Most, including myself, will automatically default to any one of these images when dinosaurs come up in conversation (what, you mean it’s not that frequent for normal people?) But we often neglect to think the earliest dinosaurs, spectacular organisms that gave birth to the most successful, and on-going, terrestrial vertebrate radiation of all time.
In the UK, many if not most Master’s students do not publish their postgraduate research. I’ve been informed by several people that in US-based institutions, Master’s students are continuously encouraged to publish their material by their supervisors and institutions.
Two years ago, I undertook an MSc at the Natural History Museum in London. One of the requirements, as with most postgraduate courses, was to undertake a research-based thesis. Out of the 21 students, so far only a single person (Roland Sookias) has had their research published. I have been informed that from at least the previous two years, this is pretty much the normal rate of publication! In fact, during the entire year I studied there, not a single supervisor/lecturer even mentioned formal publication or how to even approach manuscript preparation. This is an essential skill that all students should be taught really, and at least in my academic experience has been mysteriously neglected, by both students and their respective supervisors and lecturers it seems. This is especially the case, I feel, for Master’s students who wish to progress in academia, particularly through PhD research. Papers are academic currency, and the sooner you start accumulating wealth, the better.
In terrestrial environments, predator body size is largely correlated with prey body size. The opposite is found for many predators in the marine environment – baleen whales in particular comprise some of the world’s largest mammals and yet they feed on something far smaller (plankton). The leopard seal is unusual in that it feeds both at the top and at the bottom of the food chain, consuming large prey, such as penguins and other seals, and small prey, such as krill, an abundant basal component of the Antarctic food web. While leopard seals are well known as raptorial predators with a ‘grip and tear’ feeding styles, a large portion of their diet (krill) is too small to be eaten in this way. For this, they use filter feeding to separate the krill from seawater.
