Extinction from global warming: Changing interactions between species may be more dangerous than high temperatures alone

Summary:
A new study reviewed 136 case studies to determine the underlying causes of why many populations have gone extinct due to changing climate. According to the authors, extinctions of plant and animal populations from human-related climate change are already widespread, but the causes of these extinctions are very poorly understood. Contrary to expectations given global warming, the results of the study show that very few populations have gone extinct simply because temperatures got too hot for the plants and animals to survive.

A new study, published online Oct. 17, 2012 in Proceedings of the Royal Society B, reviewed 136 case studies to determine the underlying causes of why many populations have gone extinct due to changing climate.

The article, entitled "How does climate change cause extinction?" describes research led by John J. Wiens, an Associate Professor in the Department of Ecology and Evolution at Stony Brook University and by PhD students Abigail E. Cahill and Matthew E. Aiello-Lammens.

According to the authors, extinctions of plant and animal populations from human-related climate change are already widespread, but the causes of these extinctions are very poorly understood.

Contrary to expectations given global warming, the results of the study show that very few populations have gone extinct simply because temperatures got too hot for the plants and animals to survive.

"Instead," said Dr. Wiens, "climate change more often leads to local extinctions and declines by influencing interactions between species, such as reducing prey populations for predators. These shifting interactions may make even small climatic changes dangerous for the survival of plant and animal species. So, for example, many animals may starve to death because of climate change long before the climate gets hot enough for them to die from overheating."

Co-authors of the study include M. Caitlin Fisher-Reid, Xia Hua, Caitlin Karanewsky, Hae Yeong Ryu, Gena Sbeglia, Fabrizio Spagnolo, John Waldron, and Omar Warsi, all from the Department of Ecology and Evolution at Stony Brook University.
