Improved estimates of population extinction risk (Harding and McNamara)
An important application of theoretical ecology is in estimation of species extinction risk. Extinction models guide the selection of management regimes for endangered species. Two vital parameters in these models are the mean population growth rate and its variance. However, empirical data on population growth are rarely perfect, but are influenced by random sampling error (induced by e.g.... View News Article (2003-12-10)

Mass extinctions don't favor large vertebrates
A new study finds that, similar to the mass extinction that's underway now, the end-Devonian extinction resulted in the loss of most large-bodied vertebrates. View News Article (2015-11-13)

Picky eating potentially perilous for bats
Working in the Department of Ecology and Organismal Biology, Justin Boyles and Jonathan Storm examined the possibility of a link between dietary specialization and the risk of extinction for bats in Australia, Europe and North America. View News Article (2007-07-25)

Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. View News Article (2009-10-22)

Hermaphroditic plants have genetic advantage in areas where extinctions are frequent
In one of the first studies to empirically compare the reproductive success of hermaphrodites and male and female populations, biologists from the University of Oxford make use of the rare and extreme sexual diversity displayed in a species of European weed to test the hypothesis that hermaphrodites have been selected in regions with frequent extinction and re-colonization. View News Article (2006-02-22)

Mass extinction's cause: 'Sick Earth'
What really caused the largest mass extinction in Earth's history? View News Article (2006-10-23)

Poisonous frogs more likely to face extinction, study finds
Scientists at the University of Liverpool have found that amphibians that use toxins to protect themselves against predators are at a higher risk of extinction than those who use other types of defence, which poses a challenge to a long-held evolutionary hypothesis. View News Article (2015-10-20)

Climate change could trigger 'boom and bust' population cycles leading to extinction
Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. , according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz. View News Article (2007-04-17)

Improved predictions of warming-induced extinctions sought
In the March 2007 issue of BioScience, an international team of 19 researchers calls for better forecasting of the effects of global warming on extinction rates. View News Article (2007-03-01)

MU Researchers Use Computational Models to Study Fear
The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. View News Article (2009-10-01)
