Stomach contents and stable isotope analysis reveal Antarctic prey in short-tailed shearwaters sampled at sea
Short-tailed shearwaters Ardenna tenuirostris are seasonally abundant consumers in the Southern Ocean, but their diet in this region is debated. Among birds found on vessels at high latitudes (n = 11 live birds a...

Exposure of breeding albatrosses to the agent of avian cholera: dynamics of antibody levels and ecological implications
Despite critical implications for disease dynamics and surveillance in wild long-lived species, the immune response after exposure to potentially highly pathogenic bacterial disease agents is still poorly know...

Albatross chicks reveal interactions of adults with artisanal longline fisheries within a short range
Incidental capture in fisheries (“bycatch”) is a major threat to global marine biodiversity, especially to those species with low fecundity, such as albatrosses. Efforts to reduce bycatch have been undertaken ...

The rime of the modern mariner: evidence for capture of yellow-nosed albatross from Amsterdam Island in Indian Ocean longline fisheries
Commercial fisheries currently pose a serious threat at sea to the conservation of a number of pelagic seabirds. However, these interactions are complex, and reports on population-specific bycatch in the high...

Contrasted associations between seabirds and marine mammals across four biomes of the southern Indian Ocean
Seabirds associations with marine mammals have been shown to be an efficient way by which the seabirds can detect and access prey patches. However, these associations have been documented locally in the litera...

King-size fast food for Antarctic fur seals
The study of scats of adult male Antarctic fur seals Arctocephalus gazella (AFS) revealed occasional frequent capture of penguins. Although AFS adult males have been occasionally reported to kill king penguins Ap...
