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)…
For nearly 3 decades, geodetic Global Navigation Satellite System (GNSS) measurements in Antarctica have provided direct observations of bedrock displacement, which is linked to various geodynamic processes, including plate motion, post-seismic deformation, and glacial isostatic adjustment (GIA).
Understanding the causes of past atmospheric methane (CH4) variability is important for characterizing the relationship between CH4, global climate and terrestrial biogeochemical cycling.
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds…
The Kunming-Montreal Global Biodiversity Framework (GBF) calls for a 50% reduction in rates of invasive alien species establishment by 2030. However, estimating changes in rates of introduction and establishment is far from straightforward, particularly on a national scale.
Invasive alien insects are an important yet understudied component of the general threat that biological invasions pose to biodiversity.
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
Antarctic krill (Euphausia superba) are amongst the most abundant animals on Earth, with a circumpolar distribution in the Southern Ocean. Genetic and genomic studies have failed to detect any population structure for the species, suggesting a single panmictic population. However…
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…
Poster
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…
