Cretaceous angiosperms from an allegedly Triassic flora at Williams Point, Livingston Island, South Shetland Islands
Read more of: Cretaceous angiosperms from an allegedly Triassic flora at Williams Point, Livingston Island, South Shetland IslandsA terrestrial sequence on Livingston Island, South Shetland Islands, known as the Williams Point Beds contains a well-preserved, diverse fossil flora previously assigned a Triassic age. Because of their supposed […]

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, […]

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 […]
