This dataset includes mtDNA information for more than 200 southern elephant seals (Mirounga leonina) found at abandoned rookery sites along the Southern Victoria Land Coast (74-78 degrees south latitu
Explanations for the evolution of body size in mammals have remained surprisingly elusive despite the central importance of body size in evolutionary biology. Here, we present a model which argues tha
Paleoecological data allow not only the study of trends along deep-time chronological transects but can also be used to reconstruct ecological gradients through time, which can help identify causal fa
