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.

When it comes to extinction, body size matters

On a certain level, extinction is all about energy. Animals move over their surroundings like pacmen, chomping up resources to fuel their survival. If they gain a certain energy threshold, they ...

It All Comes Down to Energy: New Extinction Formula Includes Body Size and Metabolism

NewsExtinction models typically base continued species existence on the tug-of-war between resource density and population growth. But a new model incorporates other facets to show a more complex ...
