Unfolding personalities: the importance of studying ontogeny.
TLDR
This work argues that based on evolutionary theory, neurophysiological knowledge, and recent findings, personality is probably less stable than often thought and developmental changes in the regulation of DNA expression are probably more relevant than individual differences in DNA sequence.

Ontogeny of Diving Behaviour in the Galápagos Fur Seal
TLDR
Age was the best predictor of time spent at sea in the ontogeny of diving behaviour in the Galapagos fur seal, and body mass was thebest predictor for maximum dive depth as well as maximum and median durations.

The microevolution of the Galápagos marine iguana Amblyrhynchus cristatus assessed by nuclear and mitochondrial genetic analyses
TLDR
A scenario is proposed that explains the marine iguanas' low genetic divergence, notwithstanding their long evolutionary history in the Galápagos archipelago.

Drastic effects of El Niño on Galapagos pinnipeds
SummaryPopulation dynamics of pinnipeds living in the tropical upwelling ecosystem of the Galapagos were strongly influenced by the 1982–83 Southern Oscillation-El Niño (EN) event which was the…

Pinnipeds and El Niño : responses to environmental stress
El Nino is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. Its most obvious characteristic is the warming of surface waters, which…
Global threats to pinnipeds
The 2008 IUCN (International Union for Conservation of Nature) review of the status of the world’s mammals identified marine mammals (IUCN 2008) as disproportionally threatened and data poor compared…

Mutual Mother-Pup Recognition in Galápagos Fur Seals and Sea Lions: Cues Used and Functional Significance
TLDR
The analysis of the PACs of mothers and the bleats of pups shows that interindividual variability of calls provides a sufficient basis for individual recognition in both species.

DEVELOPMENT OF HEMOGLOBIN, HEMATOCRIT, AND ERYTHROCYTE VALUES IN GALÁPAGOS FUR SEALS
TLDR
Up to the age of 1 yr, age was the best predictor for blood values, thereafter mass needed to be a better predictor; female juveniles between the ages of 150 and 600 d had higher blood values than same-age males.

Galápagos and Californian sea lions are separate species: Genetic analysis of the genus Zalophus and its implications for conservation management
TLDR
A case is built for classifying the Galápagos sea lion, the Californian sea lion and the Japanese sea lion as true species using a set of different phylogenetic reconstruction approaches.
