Influence of krill availability on humpback whale breeding success
Abstract: The abundance of the Antarctic krill (Euphausia superba) has been declining in the western Antarctic Peninsula (WAP), probably as a consequence of the effects of the considerable increase in the sea surface temperature observed in the region. Thus, the performance (reproduction and

The impact of the hake Merluccus spp. longline fishery off South Africa on Procellariiform seabirds
Abstract: In 1994, an experimental longline fisheri for hake Merluccius spp. commenced in the shelf water of South Africa. Participants were required to record any birds caught, and these data were supplemented by ship-based observers on several vessels. Longlines are set at night, and the white

Southern right whale (Eubalaena australis) reproductive success is influenced by krill (Euphausia superba) density and climate
Abstract: The reproductive success of southern right whale (Eubalaena australis) depends on body condition and, therefore, on foraging success. This, in turn, might be affected by climatically driven change in the abundance of the species main prey, krill (Euphausia superba), on the feeding

RECRUITMENT AND BODY SIZE IN RELATION TO TEMPERATURE IN JUVENILE PATAGONIAN TOOTHFISH (DISSOSTICHUS ELEGINOIDES) AT SOUTH GEORGIA
Abstract: Recruitment variability in juvenile Patagonian toothfish (Dissostichus eleginoides), a commercially important, deepwater nototheniid fish, was examined at the sub-Antarctic island of South Georgia, South Atlantic. Data from 13 demersal trawl surveys conducted over a 20-year period were

CLIMATICALLY DRIVEN FLUCTUATIONS IN SOUTHERN OCEAN ECOSYSTEMS
Abstract: Determining how climate fluctuations affect ocean ecosystems requires an understanding of how biological and physical processes interact across a wide range of scales. Here we examine the role of physical and biological processes in generating fluctuations in the ecosystem around South

Coastal weather drives foraging behaviour of chinstrap penguins, Pygoscelis antarctica
Abstract: There is increasing interest in using higher-trophic level predators as ecosystem indicators because their performance is presumed to be linked to the overall function of the ecosystem that supports them. In the southwest Atlantic sector of the Southern Ocean, Antarctic krill (Euphausia

Disentangling the influence of three major threats on the demography of an albatross community
Abstract: Climate change, fisheries and invasive species represent three pervasive threats to seabirds, globally. Understanding the relative influence and compounding nature of marine and terrestrial threats on the demography of seabird communities is vital for evidence-based conservation. Using
