Three decades after the Chernobyl accident, the biodiversity of the area has completely recovered. The mechanisms that allow organisms to live in this area are still the subject of study and controversy.
Studying evolution in the face of environmental uncertainty is crucial to understand biological diversity, because diversifying life strategies is key to survival and reproduction in uncertain environments.
Species richness is not homogeneous in space and it normally presents differences when comparing among different sites. These differences often respond to gradients in one or several factors which create biodiversity patterns in space and are scale-dependent.
