Adélie penguin (Pygoscelis adeliae) diet is an important indicator of prevailing environmental conditions and … resource availability. In this study, dietary variation within and between years was studied with fatty acid … signature analysis (FASA), stomach content analysis (SCA)…
In 2008, the emperor penguin Aptenodytes forsteri colony at Amanda Bay, East Antarctica, was … designated an Antarctic Specially Protected Area by the 31st Antarctic Treaty Consultative Meeting in Kyiv, Ukraine.
We investigated whether diet composition determined from stable-isotope analysis … (SIA) was similar to that determined from stomach content analysis for Ad¨¦lie penguins Pygoscelis … adeliae.
The stability of Antarctic Bottom Water (AABW) to freshwater (FW) perturbations is investigated in a … coupled climate model of intermediate complexity. It is found that AABW is stable to surface freshwater … fluxes greater in volume and rate to those that permanently “shut down”…
Mitochondrial ribosomal DNA is commonly used in DNA-based dietary … analyses. In such studies, these sequences are generally assumed to be the … only version present in DNA of the organism of interest. However…
Line-transect distance sampling is a widely used method for estimating animal density from aerial surveys. Analysis of line-transect distance data usually relies on a requirement that the statistical distribution of distances of animal … groups from the transect line is uniform.
Knowledge of penguin abundance at regional and circumpolar scales across the Southern Ocean is important … for the development of ecosystem models and to estimate prey consumption by penguins to assess potential competition … with fisheries’ operations.
The Ross seal (Ommatophoca rossii) is the least studied of the Antarctic ice-breeding phocids. In … particular, estimating the population status of the Ross seal has proved extremely difficult.
1. The crabeater seal … Lobodon carcinophaga … is considered to be a key species in the krill-based foodweb … of the Southern Ocean. Reliable estimates of the abundance of this species are necessary to … allow the development of multispecies, predator…
In January 2004 the microplankton community … from the coastal waters of Terre Ade´lie and Georges V Land … (139!E–145!E) was studied. Results showed a diatomdominated … bloom with chlorophyll a levels averaging … 0.64 lg l-1 at 5 m depth (range 0.21–1.57 lg l-1).
