The Scotia Sea ecosystem is a major component of the circumpolar Southern Ocean system,
where productivity and predator demand for prey are high. The eastward-flowing Antarctic …

Icefish or white-blooded fish are a family of species, unique among vertebrates in that they
possess no haemoglobin. With the exception of one species which occurs on the southern …

Many birds show a surprising degree of intraspecific variability in migratory tendency and
choice of wintering site. In this study, we tracked the seasonal movements of 35 …

Gelatinous zooplankton are a large component of the animal biomass in all marine
environments, but are considered to be uncommon in the diet of most marine top predators …

Biomagnification of mercury (Hg) in the Scotia Sea food web of the Southern Ocean was
examined using the stable isotope ratios of nitrogen (δ 15 N) and carbon (δ 13 C) as proxies …

Environmental and anthropogenic factors often drive population declines in top predators,
but how their influences may combine remains unclear. Albatrosses are particularly …

Telemetry methods and remote sensing now make it possible to record the spatial usage of
wide‐ranging marine animals and the biophysical characteristics of their pelagic habitats …

The use of cephalopod beaks in ecological and population dynamics studies has allowed
major advances of our knowledge on the role of cephalopods in marine ecosystems in the …

The utility of upper-trophic-level species as ecosystem indicators is determined by our ability
to relate changes in indices of their performance to changes at lower trophic levels. Such …

Seabirds are often advocated as biomonitors for marine contaminants such as mercury (Hg).
However, contaminant levels can vary widely depending on among-individual and among …
