Within most natural assemblages a few species comprise the majority of the individuals (Figure 1; Preston 1948). This pattern in distribution of species abundances is accompanied on a larger scale ...

To do this, scientists rely on species distribution models (SDMs), which make predictions of species' geographical ranges ...

It consists of a container, such as a yoghurt carton, buried in the ground. The top of the container is level with the soil surface, and it is covered by a piece of wood with a slight gap to allow ...

Immediately adjacent or neighboring populations of the species vary slightly but can interbreed. But at the extremes of the distribution -- the opposite ends of the pattern that link to form a ...

Predicting local extinction rates is complex due to differences in biological diversity, species distribution, climate, vegetation, habitat threats, invasive species, consumption patterns, and enacted ...

Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing ...

Hantavirus recently made news headlines as the cause of death for Betsy Arakawa, the wife of actor Gene Hackman, but little ...

New research suggests conservation efforts could more effectively identify and protect bird species at greatest risk from climate change by better understanding the range of specific conditions they ...
