Unsupervised classification identifies coherent thermohaline structures in the Weddell Gyre region
Read more of: Unsupervised classification identifies coherent thermohaline structures in the Weddell Gyre regionThe Weddell Gyre is a major feature of the Southern Ocean and an important component of the planetary climate system; it regulates air–sea exchanges, controls the formation of deep and […]

Quantifying circumpolar summer habitat for Antarctic krill and Ice krill, two key species of the Antarctic marine ecosystem
Read more of: Quantifying circumpolar summer habitat for Antarctic krill and Ice krill, two key species of the Antarctic marine ecosystemAntarctic krill (Euphausia superba) and Ice krill (Euphausia crystallorophias) are key species within Southern Ocean marine ecosystems. Given their importance in regional food webs, coupled with the uncertain impacts of […]

Surface texture heterogeneity in maculated bird eggshells
Read more of: Surface texture heterogeneity in maculated bird eggshellsMany of the world’s 10 000 bird species lay coloured or patterned eggs. The large diversity of eggshell patterning among birds, achieved through pigment, has been attributed to a few […]

Remote Sensing of Sea Surface Glacial Meltwater on the Antarctic Peninsula Shelf
Read more of: Remote Sensing of Sea Surface Glacial Meltwater on the Antarctic Peninsula ShelfGlacial meltwater is an important environmental variable for ecosystem dynamics along the biologically productive Western Antarctic Peninsula (WAP) shelf. This region is experiencing rapid change, including increasing glacial meltwater discharge […]

Navigating Gender at Sea
Read more of: Navigating Gender at SeaFieldwork, including work done at sea, is a key component of many geoscientists’ careers. Recent studies have highlighted the pervasive harassment faced by women and LGBTQ+ people during fieldwork. However, […]

Histopathological screening of Pontogammarus robustoides (Amphipoda), an invader on route to the United Kingdom
Read more of: Histopathological screening of Pontogammarus robustoides (Amphipoda), an invader on route to the United KingdomBiological invasions may act as conduits for pathogen introduction. To determine which invasive non-native species pose the biggest threat, we must first determine the symbionts (pathogens, parasites, commensals, mutualists) they […]

Evaluating the appropriateness of risk-based approaches to assess the sustainability of fishery impacts on seabirds
Read more of: Evaluating the appropriateness of risk-based approaches to assess the sustainability of fishery impacts on seabirdsMany seabird populations are declining, with fisheries bycatch as one of the greatest threats. Explicit risk criteria should be used to identify whether bycatch is a problem for particular species […]

An expert-driven framework for applying eDNA tools to improve biosecurity in the Antarctic
Read more of: An expert-driven framework for applying eDNA tools to improve biosecurity in the AntarcticSignatories 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) methods provide new opportunities […]

Wing reduction and body size variation along a steep elevation gradient: a case study with Magellanic sub-Antarctic mayflies and stoneflies
Read more of: Wing reduction and body size variation along a steep elevation gradient: a case study with Magellanic sub-Antarctic mayflies and stonefliesIntroduction: Ecogeographical patterns in body size have been described across a wide range of vertebrate species. However, insects have shown inconsistent patterns in studies to date. Aquatic insects, particularly those […]

Expanding Antarctic biogeography: microbial ecology of Antarctic island soils
Read more of: Expanding Antarctic biogeography: microbial ecology of Antarctic island soilsThe majority of islands surrounding the Antarctic continent are poorly characterized in terms of microbial macroecology due to their remote locations, geographical isolation and access difficulties. The 2016/2017 Antarctic Circumnavigation […]
