Coscinodiscus bouvet Karsten – a distinctive diatom which may be an indicator of changes in the Southern Ocean
Read more of: Coscinodiscus bouvet Karsten – a distinctive diatom which may be an indicator of changes in the Southern OceanThe centric diatom Coscinodiscus bouvet Karsten is a distinctive Antaretic endemic species whose distribution can be assessed reliably from a large body of literature. It appears to be typically neritic, […]

Shallow marine sedimentation within an active margin basin, James Ross Island, Antarctica
Read more of: Shallow marine sedimentation within an active margin basin, James Ross Island, AntarcticaThe Santa Marta Formation exposed on northern James Ross Island, Antarctica, represents shallow marine shelf sedimentation within an active margin basin. The formation is approximately 1000 m thick, is of […]

Arrhenian growth thermodynamics in marine-derived tropical Fusarium equiseti and polar Pseudogymnoascus spp. in a liquid culture system
Read more of: Arrhenian growth thermodynamics in marine-derived tropical Fusarium equiseti and polar Pseudogymnoascus spp. in a liquid culture systemWe hypothesised that the activation energy (Ea) of growth in a marine-derived tropical strain of Fusarium equiseti and polar strains of Pseudogymnoascus spp. grown for 10 days in a liquid […]

Evidence for the long-term sedimentary environment in an Antarctic subglacial lake
Read more of: Evidence for the long-term sedimentary environment in an Antarctic subglacial lakeLakes beneath the Antarctic Ice Sheet are of fundamental scientific interest for their ability to contain unique records of ice sheet history and microbial life in their sediments. However, no […]

A global cline in a colour polymorphism suggests a limited contribution of gene flow towards the recovery of a heavily exploited marine mammal
Read more of: A global cline in a colour polymorphism suggests a limited contribution of gene flow towards the recovery of a heavily exploited marine mammalEvaluating how populations are connected by migration is important for understanding species resilience because gene flow can facilitate recovery from demographic declines. We therefore investigated the extent to which migration […]

Read more of: Persistent Organic Pollutants in two species of migratory birds from Rothera Point, Adelaide Island, AntarcticaCarcasses of South Polar Skuas (Catharacta maccormicki) and Kelp gulls (Larus dominicanus) were opportunistically collected around of Rothera Research station (67°35′8″S and 68°7′59″W) during the 2016/2017 austral summer. Samples of […]

Identification of marine important bird and biodiversity areas for penguins around the South Shetland Islands and South Orkney Islands
Read more of: Identification of marine important bird and biodiversity areas for penguins around the South Shetland Islands and South Orkney IslandsAim: To provide a method of analyzing penguin tracking data to identify priority at-sea areas for seabird conservation (marine IBAs), based on pre-existing approaches for flying seabirds but revised according […]

Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguins
Read more of: Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguinsThe mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental […]

Not so free range? Oviposition microhabitat and egg clustering affects Eretmoptera murphyi (Diptera: Chironomidae) reproductive success
Read more of: Not so free range? Oviposition microhabitat and egg clustering affects Eretmoptera murphyi (Diptera: Chironomidae) reproductive successUnderstanding the physiology of non-native species in Antarctica is key to elucidating their ability to colonise an area, and how they may respond to changes in climate. Eretmoptera murphyi is […]

Attendance patterns and behaviour in relation to experience and pair-bond formation in the Wandering Albatross Diomedea exulans at South Georgia
Read more of: Attendance patterns and behaviour in relation to experience and pair-bond formation in the Wandering Albatross Diomedea exulans at South GeorgiaRecruitment of Wandering Albatrosses Diomedea exulans to the breeding population at South Georgia took between 2 and 8 years after they first returned to their natal colony. In successive seasons, […]
