Blood fatty acids indicate inter- and intra-annual variation in the diet of Adélie penguins: Comparison with stomach content and stable isotope analysis Journal of Experimental Marine Biology and Ecology, 2008 (Ref: 13745)
Category 1: Peer-reviewed literature

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)…

Population estimates of emperor penguins at Amanda Bay, Ingrid Christensen Coast, Antarctica Polar Record, 2008 (Ref: 13738)
Category 1: Peer-reviewed literature

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.

Evaluating and using stable-isotope analysis to infer diet composition and foraging ecology of Adélie penguins Pygoscelis adeliae Marine Ecology Progress Series, 2008 (Ref: 13308)
Category 1: Peer-reviewed literature

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.

Stability of Antarctic Bottom Water formation to freshwater fluxes and implications for global climate Journal of Climate, 2008 (Ref: 13446)
Category 1: Peer-reviewed literature

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”…

Pseudogenes and DNA-based diet analyses: a cautionary tale from a relatively well sampled predator-prey system Bulletin of Entomological Research, 2008 (Ref: 13350)
Category 1: Peer-reviewed literature

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…

The influence of animal mobility on the assumption of uniform distances in aerial line-transect surveys Wildlife Research, 2008 (Ref: 13474)
Category 1: Peer-reviewed literature

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.

Detectability of penguins in aerial surveys over the pack-ice off Antarctica Wildlife Research, 2008 (Ref: 13475)
Category 1: Peer-reviewed literature

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.

Estimating population status under conditions of uncertainty: the Ross seal in East Antarctica Antarctic Science, 2008 (Ref: 13279)
Category 1: Peer-reviewed literature

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.

Taking account of dependent species in Management of the Southern Ocean krill fishery: estimating crabeater seal abundance off east Antarctica Journal of Applied Ecology, 2008 (Ref: 13310)
Category 1: Peer-reviewed literature

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…

A study of the diatom-dominated microplankton summer assemblages in coastal waters from Terre Adélie to the Mertz Glacier, East Antarctica (139°E-145°E) Polar Biology, 2008 (Ref: 13524)
Category 1: Peer-reviewed literature

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).
