To examine the potential of lipids as dietary markers in Euphausia superba Dana, juvenile … krill were fed 4 phytoplankton diets (diatoms, cryptomonads, dinoflagellates and thraustochytrids … over a range of food concentrations) and 2 species of zooplankton (rotifers and Artemia sp.) for 20 d.
Two phytoplankton diets with markedly different fatty acid (FA) profiles (thraustochytrid … and diatom over a range of concentrations) were fed to juvenile Euphausia superba Dana to … evaluate the time lapse required for the development of trophic lipid signatures in the digestive gland … (DG).
[1] We analyzed d29Si of dissolved silicate for eight water column profiles across the … Southern Ocean (south of Australia in spring 2001) from the Seasonal Ice Zone (SIZ) north to the Subantarctic Zone (SAZ), including the first isotopic compositions measured … for Si-depleted seawaters.
We present water column profiles of excess particulate Ba (Baxs, an estimate of biogenic Ba from total particulate Ba … after small corrections for lithogenic Ba) along a transect in the Australian sector of the Southern Ocean from the … Subantarctic Zone (SAZ) to the Sea Ice Zone during spring…
We report a 2000-year Antarctic ice-core record of stable carbon isotope measurements in atmospheric methane (ä13CH4). Large ä13CH4 variations indicate that the methane budget varied unexpectedly during the late preindustrial Holocene (circa 0 to 1700 A.D.). During the first thousand years…
ABSTRACT: Predictive species–environment models have numerous ecological and management applications, and can provide insight into the functional relationships between a species and its environment.
Polar organisms have adapted their seasonal cycles to the dynamic interface between ice and water. This interface ranges from the micrometre-sized brine channels within sea ice to the planetary-scale advance and retreat of sea ice.
