Use of accelerometry to measure the dynamics of activity patterns of Atlantic bluefin tuna after tagging and release
Read more of: Use of accelerometry to measure the dynamics of activity patterns of Atlantic bluefin tuna after tagging and releaseResearch on the direct effects of capture and tagging on post-release behaviour is typically limited to short-term deployments. To investigate the initial and longer-term behavioural responses to capture and tagging, […]

The foraging distribution and habitat use of chick-rearing snow petrels from two colonies in Dronning Maud Land, Antarctica
Read more of: The foraging distribution and habitat use of chick-rearing snow petrels from two colonies in Dronning Maud Land, AntarcticaThe polar sea-ice zones are highly productive and seasonal habitats that support large populations of vertebrate predators. In the Antarctic, snow petrels ( Pagodroma nivea ) are regarded as highly […]

Micromolecular Adaptations in Antarctic Echinoderms: Overlapping Roles of Organic Osmolytes in Osmoregulation and Protein Stability Under Low Temperature
Read more of: Micromolecular Adaptations in Antarctic Echinoderms: Overlapping Roles of Organic Osmolytes in Osmoregulation and Protein Stability Under Low TemperatureFor osmoconforming organisms, prolonged exposure to reduced salinity requires an adjustment to intracellular osmolyte levels to ensure an osmotic balance is maintained between the cell and external sea water. However, […]

Regional emperor penguin population declines exceed modelled projections
Read more of: Regional emperor penguin population declines exceed modelled projectionsEmperor penguin populations are predicted to decline rapidly over the current century owing to habitat loss in Antarctica arising from warming oceans and loss of seasonal sea ice. Previous work […]

Thin and ephemeral snow shapes melt and runoff dynamics in the Peruvian Andes
Read more of: Thin and ephemeral snow shapes melt and runoff dynamics in the Peruvian AndesThe snow and glaciers of the Peruvian Andes provide vital water supplies in a region facing water scarcity and substantial glacier change. However, there remains a lack of understanding of […]

Successful deployment of a large uncrewed aerial vehicle for multidisciplinary science from Rothera Research Station, Antarctica: 2024 season overview and lessons learned
Read more of: Successful deployment of a large uncrewed aerial vehicle for multidisciplinary science from Rothera Research Station, Antarctica: 2024 season overview and lessons learnedAirborne investigations are a keystone for understanding the Antarctic environment across many scientific disciplines. Over the past decade and more, the use of drones has been proposed as a means […]

The Genomic Signature of Demographic Decline in a Long-Distance Migrant in a Range-Extreme Population
Read more of: The Genomic Signature of Demographic Decline in a Long-Distance Migrant in a Range-Extreme PopulationMigratory birds are inherently vagile, a strategy that may reduce the impacts of habitat loss and fragmentation on genetic diversity. However, specialist resource requirements and range-edge distribution can counteract these […]

Sensitivity of near-surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configuration
Read more of: Sensitivity of near-surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configurationNear-surface marine winds in coastal Antarctica have global importance, as they affect ocean circulation and sea-ice variability. We test the sensitivities of simulated near-surface winds and wind stress in coastal […]

Implementing Geomagnetically Induced Currents Mitigation During the May 2024 “Gannon” G5 Storm: Research Informed Response by the New Zealand Power Network
Read more of: Implementing Geomagnetically Induced Currents Mitigation During the May 2024 “Gannon” G5 Storm: Research Informed Response by the New Zealand Power NetworkIn early May 2024 ∼6 Coronal Mass Ejections were launched toward the Earth in shortsuccession. This triggered the G5 “Gannon” geomagnetic storm lasting from ∼17 UT on 10 May 2024 […]
