Genetic and morphometric differentiation between island and mainland southern elephant seal populations
(The Royal Society, 2001-02)
We compare genetic (both nuclear and mitochondrial) and morphometric measures between two putative populations of southern elephant seal (Mirounga leonina), and interpret the results in the context of data from mark-recapture ...
Long-Term Population Trends of Patagonian Marine Mammals and Their Ecosystem Interactions in the Context of Climate Change

(Wiley, 2021)
Facial compartmentalization in the skull of extant pygmy whales (Kogiidae) is a unique feature among cetaceans that allows for the housing of a wide array of organs responsible for echolocation. Recent fossil findings ...
