Baleen whales are extreme capital breeders, capable of fasting for more than half a year while migrating thousands of kilometres and nursing rapidly growing offspring that quadruple in body size over the same period. To understand this energetic conundrum…
Fuel spills are a major source of contamination in terrestrial environments in Antarctica. Little is known of the effects of hydrocarbon contaminants in fuels on Antarctic terrestrial biota, and how these change as fuel ages within soil.
The gammarid Paramoera walkeri is one of the most abundant amphipods in near-shore Antarctic waters. There has been increasing interest in P. walkeri as a test species for ecotoxicology studies and bio-monitoring for contaminants in Antarctica…
Simultaneous effects of ocean acidification and temperature change in Antarctic environments warrant investigation as little is known about the synergistic consequences of these factors on Antarctic benthic species.
Effects of ocean acidification in conjunction with temperature change warrants investigation as little is known about potential interactive effects of these parameters on Antarctic benthic species.
When resources are limited or patchy, a species may develop some degree of resource … partitioning to reduce intra-specific competition. Development of intra-specific resource partitioning … is more pronounced in species with clear phenotypic variation among individuals (e.g. age or sex).
Understanding the cryptic lives of wide–ranging wild animals such as seals can be challenging, but with the … advent of miniaturised telemetry and data–logging devices this is now possible and relatively straightforward. However…
