Competition-induced starvation drives large-scale population cycles in Antarctic krill
Abstract: Antarctic krill (Euphausia superba)—one of the most abundant animal species on Earth—exhibits a five to six year population cycle, with oscillations in biomass exceeding one order of magnitude. Previous studies have postulated that the krill cycle is induced by periodic climatological

Spatial and temporal distribution patterns of acoustic backscatter in the New Zealand sector of the Southern Ocean
Abstract: Mid-trophic level organisms (MTLO) of open-ocean marine ecosystems play a key role linking primary and tertiary consumers. Despite their importance, characterisation of MTLO is limited due to sampling difficulty, and is largely obtained through active acoustics. Acoustic data collected

Predicting distribution and relative abundance of mid-trophic level organisms using oceanographic parameters and acoustic backscatter
Abstract: Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the pelagic open-ocean ecosystem are normally sparse or absent. Consequently, ecosystem models are limited in their ability to support decision-making for issues ranging from fisheries management to

Diet overlap among top predators at the South Orkney Islands, Antarctica
Abstract: In order to understand interspecific trophic relationships among top predators, we analyzed diet information on nine bird and two seal species collected in the austral summer from 1996 to 2000 at South Orkney Islands. Overall, the diet of most of the predators was mainly composed of

Foraging patterns in the Antarctic Shag Phalacrocorax bransfieldensis at Harmony Point, Antarctica
Abstract: During the 1995 and 1996 summer seasons the foraging patterns of the Antarctic Shag Phalacrocorax bransfieldensis were studied by direct observation on individuals breeding at Harmony Point, Nelson Island, South Shetland Islands. During pre-laying and incubation individuals of both sexes

Long term movements and activity patterns of an Antarctic marine apex predator: the leopard seal
Abstract: Leopard seals are an important Antarctic apex predator that can affect marine ecosystems through local predation. Here we report on the successful use of micro geolocation logging sensor tags to track the movements, and activity, of four leopard seals for trips of between 142-446 days
