TL;DR: This paper analyzes the status of knowledge of marine biodiversity in five subregions along the Atlantic and Pacific coasts of South America: the Tropical East Pacific, the Humboldt Current, the Patagonian Shelf, the Brazilian Shelves, and the Tropical West Atlantic, and it provides a review of ecosystem threats and regional marine conservation strategies.

TL;DR: The possibility that individual southern elephant seals are pursuing specialist foraging strategies to avoid competition, both with one another, and with the South American sea lions that breed nearby is discussed.

Breeding biology of southern elephant seals in patagonia
TL;DR: Parameters of the breeding season for the expanding Patagonia colony are similar to those for declining southern elephant seal populations elsewhere, and thermal conditions, day length and food availability may explain clines in the timing of breeding events.

Growth and distribution of a southern elephant seal colony
TL;DR: In contrast with most southern elephant seal, Mirounga leonina, colonies, births at Peninsula Valdes, Argentina, increased from 7,455 in 1982 to 9,636 in 1990, and colony size during the 1990 breeding season, including pups, was estimated at 19,000.

Proximate composition and energetic value of demersal and pelagic prey species from the Southwestern Atlantic Ocean
TL;DR: The energetic value of teleosts from the Southwestern Atlantic Ocean was not different from those of the Pacific or Indian Southern Ocean, but was higher than the energetic value from the Northern Hemisphere.
