Human- and animal-impacted sites in Antarctica can be contaminated with heavy metals, as well as areas influenced by underlying geology and naturally occurring minerals. The present study examined the relationship…Read more on Influence of heavy metals on the occurrence of Antarctic soil microalgae

To fully decipher the role of nitrate photolysis on the atmospheric oxidative capacity in snow-covered regions, NOx flux must be determined with more precision than existing estimates. Here, we introduce…Read more on New estimation of the NOx snow-source on the Antarctic Plateau

Ice is one of the most important drivers of population dynamics in polar organisms, influencing the locations, sizes, and connectivity of populations. Antarctic fur seals, Arctocephalus gazella, are particularly interesting…10 September, 2021
In species that live in family groups, such as cooperative breeders, inbreeding is usually avoided through the recognition of familiar kin. For example, individuals may avoid mating with conspecifics encountered…

A long-standing paradox of marine populations is chaotic genetic patchiness (CGP), temporally unstable patterns of genetic differentiation that occur below the geographic scale of effective dispersal. Several mechanisms are hypothesized…9 September, 2021 by Emma Young
Quantifying the level of population connectivity within and between geographically separated single-species deep-water fisheries stocks will be vital for designing effective management plans to preserve such populations. Despite this, stock…9 September, 2021 by Rachel Cavanagh
Sharks and rays are at risk of extinction globally. This reflects low resilience to increasing fishing pressure, exacerbated by habitat loss, climate change, increasing value in a trade and inadequate…9 September, 2021
With the advent of chromatin-interaction maps, chromosome-level genome assemblies have become a reality for a wide range of organisms. Scaffolding quality is, however, difficult to judge. To explore this gap,…8 September, 2021 by Peter Convey
Antarctic Specially Protected Areas (ASPAs) provide the strongest environmental protection in Antarctica. However, they are not immune from anthropogenic pollution of marine or terrestrial origin. We document anthropogenic debris within…Read more on Anthropogenic debris in an Antarctic Specially Protected Area in the maritime Antarctic

Landforms produced beneath former ice sheets offer insights into inaccessible subglacial processes and present analogues for how current ice masses may evolve in a warming climate. Large subglacial channels cut…Read more on Tunnel valley infill and genesis revealed by high-resolution 3-D seismic data
