The use of molecular assays to assess the presence of species using environmental DNA (eDNA) and RNA (eRNA) as analytes has diversified as the field of environmental surveillance advances. These methods can be used, for example…
The use of environmental DNA (eDNA) and RNA (eRNA) methods is a rapidly advancing field that provides fast, cost-effective, non-invasive methods to identify the presence of target species. These methods can be used, for example…
Antarctic krill (Euphausia superba) is a keystone species of the Southern Ocean, vastly abundant and an essential food source of some of the Southern Ocean's most charismatic predators, including penguins, seals, and baleen whales. Antarctic krill are also targeted by a krill fishery…

Environmental DNA (eDNA)-based methods are increasingly used by government agencies to detect pests and threatened species, and for broader biodiversity monitoring. Given rapid technological advances and a growing number of commercial service providers…
Antarctic krill (Euphausia superba) is a keystone species in the Southern Ocean ecosystem, and monitoring its distribution and abundance is crucial for the sustainable management of expanding fisheries targeting the species. Environmental DNA (eDNA)…
The relationships between flying Antarctic seabirds and their at-sea environments remain poorly understood, particularly outside of the breeding season. Improving our knowledge of how these marine predators use their habitat is a critical step towards conservation of these species.
The contamination of the marine environment surrounding coastal Antarctic research stations remains insufficiently understood in terms of its extent, persistence, and characteristics. We investigated the presence of contaminants in marine sediments near Casey Station…
Due to its persistence and potential ecological and health impacts, mercury (Hg) is a global pollutant of major concern that may reach high concentrations even in remote polar oceans. In contrast to the Arctic Ocean…
The first year of life is critical for large mammals to acquire foraging and predator avoidance skills. Southern elephant seal (Mirounga leonina) pups wean at approximately three weeks of age and depart on their first foraging trips in midsummer…
