Coping with Climate Change - Evolution in the News
June 2009. Climate change is impacting species across the planet, and the pace of climate change is major issue. One question people are asking is whether or not species can adapt to the changes quickly enough to survive. Dr. George Gilchrist, Professor of Biology at the College of William and Mary, talks about species ability to adapt or acclimate to changing conditions.NESCent and Understanding Evolution collaborate to bring you monthly Evolution in the News stories and podcasts. The stories, along with links to background literature and classroom resources are available on the Understanding Evolution site and the podcasts are available here.

Elizabeth Derryberry - Interviews with Scientists
Elizabeth Derryberry was a graduate student in Steve Nowicki's lab at Duke University. In 2007, she published a paper describing the evolution of mating barriers within songbird groups. In this podcast, she provides background information for the question she investigated, and describes how she did the experiment. The key concept concerns the causes of speciation, specifically how mating barriers arise between populations.Published 4 years ago

Tough Conservation Choices? Ask Evolution! - Evolution in the News
Conservation of an entire ecosystem is not always possible, but how can we decide which members of the ecocsystem are most important in maintaining a healthy ecosystem? Nick Haddad talks about a paper that provides an effective guideline to conservation of plants based on their evolutionary relationships. December 2008.Published 4 years ago
HIV's Not-So-Ancient History - Evolution in the News
Understanding when and how pathogens such as HIV become human pathogens can help us control the diseases with which we live and prevent future pathogen transfers. Dr. Katia Koelle talks about what we can learn from reconstructing viral histories, including some unexpected applications. November 2008.Published 4 years ago
Evolution's Dating and Mating Game - Evolution in the News
As in most animals, octopus love life is full of interesting behavoirs. In this story, research by Christine Huffard, Roy Caldwell, and Farnis Boneka, shed light on two particularly interesting behavoirs: mate guarding and sneaking. Both are evolutionary adaptations to increase the number of a male's offspring. May 2008.Published 4 years ago
Superbug, Super-Fast Evolution - Evolution in the News
Methicillin resistant Staphylococcus aureus, or MRSA, is an increasingly common medical problem. MRSA is a strain of Staphylococcus aureus that has evolved multiple drug resistance. Infections caused by normal S. aureus are fairly easy to treat with antibiotics, but an infection caused by MRSA is very difficult to treat and can be life threatening. In this podcast Dr. Christina Burch from the University of North Carolina at Chapel Hill, talks about the evolution of drug resistance in commensal bacteria like S. aureus.

The New Shrew That's Not... - Evolution in the News
This podcast provides information about the geographic location of the grey faced sengi habitat, and the phylogenetic classification of sengis with the Afrotheria - a group that includes elephants, dugongs, tenrecs and aardvarks. Dr.s Kathleen Smith and Samantha Price of NESCent provide additional insight into the historical biogeography and phylogenetic classification of these organisms in an interview, as well as the concept of "living fossils" and how ideas develop and change in science.
