Rodent Size Linked To Human Population And Climate Change

The head shape and overall size of rodents has been changing over the past century and a University of Illinois-Chicago ecologist has tied these changes to human population density and climate change.

You probably hadn't noticed - but the head shape and overall size of rodents has been changing over the past century. A University of Illinois at Chicago ecologist has tied these changes to human population density and climate change.

The finding is reported by Oliver Pergams, UIC research assistant professor of biological sciences, in the July 31 issue of PLoS One.

Pergams said that such size-and-shape changes in mammals, occurring around the world in less than a century, are quite substantial.
