Abstract The Falkland Islands marine environment host a mix of temperate and subantarctic
species. This review synthesizes baseline information regarding ontogenetic migration …

The diet of free-living pinnipeds is most frequently estimated through identification of otoliths,
squid mouth-parts and exoskeletons of prey in scats. This is because, although important …

Individual specialisation is increasingly recognised to be an ecological and evolutionary
process having important consequences for population dynamics of vertebrates. The South …

There are not “universal methods” to determine diet composition of predators. Most
traditional methods are biased because of their reliance on differential digestibility and the …

Individual specialization, which describes whether populations are comprised of dietary
generalists or specialists, has profound ecological and evolutionary implications. However …

We examined the diet of 4 annual fishes, Austrolebias viarius, Austrolebias cheradophilus,

This study assessed ontogenetic dietary changes in male South American fur seals
Arctocephalus australis in northern and central Patagonia (Argentina) using stable isotope …

Abstract Stomach contents of South American (Arctocephalus australis)(n= 219)(SAFS) and
sub‐Antarctic (A. tropicalis)(n= 37)(SFS) fur seals were opportunistically sampled from 1980 …

Trophically-transmitted parasites are regularly exposed to potential new hosts through food
web interactions. Successful colonization, or switching, to novel hosts, occur readily when …
