1. Increasing abundance of Type A killer whales (Orcinus orca) in the coastal waters around the Antarctic Peninsula

   Abstract:  The physical marine environment around the Antarctic Peninsula (AP) is rapidly changing and we need to understand the impact on marine ecosystems. A diverse community of killer whales (Orcinus orca; Types B1, B2 and A) are important top predators around the AP, but there are currently no

2. Estimating nest-level phenology and reproductive success of colonial seabirds using time-lapse cameras

   Abstract:  We wish to draw the attention of Members to an online application of the R code published in the attached paper. The web-based app ‘photoR’ (https://jefferson.shinyapps.io/photor2) implements  the methods of the paper and provides summary outputs for direct input to CEMP A6b and A9

3. Impacts of rising sea temperature on krill increase risks for predators in the Scotia Sea

   Abstract:  Climate change is a threat to marine ecosystems and the services they provide, and reducing fishing pressure is one option for mitigating the overall consequences for marine biota. We used a minimally realistic ecosystem model to examine how projected effects of ocean warming on the

5. 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

6. 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

7. 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

10. 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
