When it comes to extinction, body size matters

When it comes to extinction, body size matters Models for extinction risk are necessarily simple. Most reduce complex ecological systems to a linear relationship between resource density and population growth -- something that can be broadly applied to infer how much resource loss a species can survive. This week in Nature Communications, an interdisciplinary team of scientists proposes a more nuanced model for extinction that also shows why animal species tend to evolve toward larger body sizes. http://ift.tt/eA8V8J
