Abstract The Ross Sea, a large, high-latitude (72–78° S) embayment of the Antarctic
continental shelf, averages 500 m deep, with troughs to 1,200 m and the shelf break at 700 …

Stomach content analysis (SCA) and more recently stable isotope analysis (SIA) integrated
with isotopic mixing models have become common methods for dietary studies and provide …

Biological responses to climate and environmental changes in remote polar regions are of
increasing interest in global change research. Terrestrial and marine polar ecosystems have …

Well-preserved remains of bone, tissue, and eggshell of Adélie Penguin (Pygoscelis
adeliae) have been recovered from numerous abandoned colonies in the Ross Sea region …

Specialization is a common mechanism of niche differentiation that can lead to ecological co-
existence among species. However, species with specialized habitat or dietary requirements …

The nototheniid Pleuragramma antarcticum (Boulenger, 1902), is the dominant pelagic fish
in waters of the continental shelf in High Antarctic regions. Larvae and juveniles of this …

Seabirds are ideal model organisms to track mercury (Hg) through marine food webs as they
are long-lived, broadly distributed, and are susceptible to biomagnification due to foraging at …

The adaptations used by notothenioid fish to combat extreme cold may have left these fish
poorly poised to deal with a changing environment. As such, the expected environmental …

Ornithogenic or bird-formed soils have accumulated in many coastal regions around
Antarctica as a result of breeding activities by pygoscelid penguins, especially the Adélie …

Production of methylmercury (MeHg) in ocean waters and its bioaccumulation in marine
organisms are critical processes controlling the fate and toxicity of mercury (Hg). However …
