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.
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.
Due to the extreme environmental conditions of the Antarctic continental shelf – its distance from other continents, depth, and the weight of the continental ice – it offers us a great opportunity to better understand how a pristine ecosystem would normally be.
