Incidental mortality in fisheries is a major driver of population declines for albatrosses and petrels globally. However, accurate identification of species can be difficult due to the poor condition of bycaught birds and/or visual similarities between closely related species.
Signatories to the Antarctic Treaty System's Environmental Protocol are committed to preventing incursions of non-native species into Antarctica, but systematic surveillance is rare. Environmental DNA (eDNA)…
The rate and extent of global biodiversity change is surpassing our ability to measure, monitor and forecast trends. We propose an interconnected worldwide system of observation networks — a global biodiversity observing system (GBiOS)…
Monitoring variability in predator diets can highlight key parameters for understanding and managing marine ecosystems. Penguin diets provide useful indicators of ecosystem variability and several species, including Adélie penguins (Pygoscelis adeliae)…
Airborne environmental DNA (airborne eDNA) analysis leverages the globally ubiquitous medium of air to deliver broad species distribution data and support ecosystem monitoring across diverse environments. As this emerging technology matures…
Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been … developed to evaluate population genetic trends without necessarily collecting new genetic data. Such "genetic diversity … indicators" enable rapid…
Antarctica and the Southern Ocean are key elements in the physical and biological Earth system. Human-induced climate change, and other human activities in the region, are leading to several potential interacting tipping points with major and irreversible consequences. Here…
Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed…
Genetic diversity is fundamental to biological diversity, vital for species’ health and adaptation to environmental change. Under the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF)…
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions…
Antarctic krill are a fundamental component of Southern Ocean ecosystems and perturbations to krill populations have ramifications for the entire ecosystem. Krill are fished across the Southern Ocean and sustainable management of this fishery is a high priority for the Australian Government.
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…
