Write About Research – A GEE Research Blog Competition

Tue, 03 Mar 2015 15:28:43 +0000

The GEE Research blog communicates UCL science with a wider, non-specialist audience, by providing short summaries of recent research in the department of UCL Genetics, Evolution and Environment. This provides an opportunity to engage with a broad audience, including other academics, students, members of the public, and even businesses and policy-makers. It is a great […]

Was Fermentation Key to Yeast Diversification?

Tue, 17 Feb 2015 15:30:43 +0000

From bread to beer, yeast has shaped our diets and our recreation for centuries. Recent research in GEE shows how humans have shaped the evolution of this important microorganism. As well as revealing the evolutionary origins of modern fission yeast, the new study published in Nature Genetics this month shows how techniques developed for detecting […]

Planning for the Future – Resilience to Extreme Weather

Thu, 15 Jan 2015 15:13:14 +0000

As climate change progresses, extreme weather events are set to increase in frequency, costing billions and causing immeasurable harm to lives and livelihoods. GEE’s Professor Georgina Mace contributed to the recent Royal Society report on “Resilience to Extreme Weather”, which predicts the future impacts of increasing extreme weather events, and evaluates potential strategies for improving […]

Forecasting Extinction

Mon, 05 Jan 2015 11:33:21 +0000

Classifying a species as either extinct or extant is important if we are to quantify and monitor current rates of biodiversity loss, but it is rare that a biologist is handy to actually observe an extinction event. Finding the last member of a species is difficult, if not impossible, so extinction classifications are usually estimates […]

Changing Perspectives in Conservation

Thu, 18 Dec 2014 12:15:44 +0000

Our views of the importance of nature and our place within have changed dramatically over the the last century, and the prevailing paradigm has profound influences on conservation from the science that is conducted to the policies that are enacted. In a recent perspectives piece for Science, GEE’s Professor Georgina Mace considered the impacts that […]

Marsupial carnivores, including bizarre pouched lions, wolves, and sabretooths, were once as diverse in their appearance as their placental counterparts are today, according to new research.

Millions of years ago large marsupial carnivores dominated both Australasia and South America.  Today, the Tasmanian Devil is the largest marsupial carnivore left, and is on the brink of extinction. Why these large pouched predators have dwindled is a mystery, but one explanation is that they couldn’t compete with their placental counterparts, like ordinary lions and tigers, because of the constraints of marsupial development. 

Marsupial Sabretooth

Now, by looking at the skulls of living and  fossil marsupial and placental carnivores from around the world, scientists have shown that the diversity between species in marsupial carnivores was in fact slightly greater than it is in more familiar placental carnivores, even though there were fewer species overall.  The research is published today in the Proceedings of the Royal Society B.
