Diet variability and reproductive performance of macaroni penguins (Eudyptes chrysolophus) at Bird Island, South Georgia
Abstract: We analysed summer diet and fledging mass of macaroni penguins Eudyptes chrysolophus breeding at Bird Island, South Georgia during the crèche period (January and February) between 1989 and 2010. Crustaceans were the main prey accounting for over 90 % of the diet by mass. Antarctic krill

Warming effects in the Western Antarctic Peninsula Ecosystem: the role of population dynamic models for explaining and predicting penguin trends
Abstract: The Western Antarctica Peninsula and Scotia Sea ecosystems appear to be driven by complex links between climatic variables, primary productivity, krill and avian predators. There are several studies reporting statistical relationships between climate, krill and penguins population size.

Linking fish and shags population trends
Abstract: This document analyses and relates long term information on population trends of inshore demersal fish and Antarctic shags of the South Shetland Islands. The analysis is complemented with comparable information on diet, foraging patterns and breeding output of shags from the Danco Coast,

Some peculiarities of the distribution and fishing of Euphausia superba in the Indian sector of the Southern Ocean (by results of USSR fleet operations in 1970–1990)
Abstract: Annually (from 1973 to 1991) 1-4 fishing vessels carried out research and scouting operations in the Indian sector of the Southern Ocean (statistical divisions 58.4.1 and 58.4.2) for the purposes of the searching of fishable aggregations of Antarctic krill (Euphausia superba). Commercial

Precautionary spatial protection to facilitate the scientific study of habitats and communities under ice shelves in the context of recent, rapid, regional climate change
Abstract: Recent, rapid climate change is now well documented in the Antarctic, particularly in the Antarctic Peninsula region. One of the most evident signs of climate change has been ice shelf collapse; overall, 87% of the Peninsula’s glaciers have retreated in recent decades. Ice shelf collapse

Sensitivity analysis identifies high influence sites for estimates of penguin krill consumption on the Antarctic Peninsula
Abstract: Krill consumption by natural predators represents a critical link between surveys and models of standing krill biomass and the design of a sustainable krill fishery for the Scotia Sea. Antarctic krill (Euphausia superba) is a significant component of diet for penguins breeding in this

Synopsis of data from satellite telemetry of foraging trips and migration routes of penguins and pinnipeds from the South Shetland Islands, 1997/98 to present
Abstract: We present a synopsis of the US AMLR satellite telemetry data, including both ARGOS and GPS positions estimates, to inform spatial planning efforts in the Antarctic Peninsula and Scotia Sea region. Identifying the patterns of habitat utilization by marine organisms is critical for proper

Assessing indicators for feedback monitoring and management of the krill fishery: data and methods for assessing predator productivity as an indicator
Abstract: One indicator that has been proposed for use in a feedback management system for the krill fishery is an estimate of predator productivity attributable to consumption of harvested species. We illustrate some of the data and methods that could be used for measuring and evaluating this
