Population structure and historical demography of South American sea lions provide insights into the catastrophic decline of a marine mammal population [PDF]

Royal Society Open Science, 2016
Understanding the causes of population decline is crucial for conservation management. We therefore used genetic analysis both to provide baseline data on population structure and to evaluate hypotheses for the catastrophic decline of the South American ...

Sea lion Otaria flavescens as host of the common vampire bat Desmodus rotundus [PDF]

Marine Ecology Progress Series, 2008
We explored how the common vampire bat Desmodus rotundus is able to survive on hyper-arid rocky islands along the Peruvian coast in the absence of plants and terrestrial mammals. We used carbon and nitrogen stable isotope analyses on D. rotundus hairs and feces to assess the pri- mary source of food, and compared our results with field observations ...
