Rb-Sr and U-Pb geochronology of neoblasts and porphyroclasts constrain movements along reactivated segments of the Outer Hebrides Fault Zone, NW Scotland
Read more of: Rb-Sr and U-Pb geochronology of neoblasts and porphyroclasts constrain movements along reactivated segments of the Outer Hebrides Fault Zone, NW ScotlandThe crustal-scale Outer Hebrides Fault Zone (OHFZ) (NW Scotland) was initiated as a Stenian-Tonian (1040-950 Ma) ductile thrust, as determined by published U-Pb dating of syn-kinematic apatite. Thrust-related mylonites were […]

Examining the Nuna-Rodinia supercontinent cycle in East Antarctica and testing correlations to the southwest United States: evidence from the Read Group (Shackleton Range) and the Nimrod Complex
Read more of: Examining the Nuna-Rodinia supercontinent cycle in East Antarctica and testing correlations to the southwest United States: evidence from the Read Group (Shackleton Range) and the Nimrod ComplexThe Read Group of the southern Shackleton Range and the Nimrod Complex of the central Transantarctic Mountains (cTAMs) form two cratonic blocks with unknown spatial extent and ambiguous crustal affinities. […]

From noise to nature: diffusion models to advance wildlife detection in aerial imagery
Read more of: From noise to nature: diffusion models to advance wildlife detection in aerial imageryAutomated wildlife detection in aerial imagery can expand the scale and efficiency of ecological monitoring, but model development is often constrained by limited training data, uneven class representation, and poor […]

Decoding diets: a novel DNA-based approach for identifying cephalopods from beaks
Read more of: Decoding diets: a novel DNA-based approach for identifying cephalopods from beaksCephalopods play a key role in marine ecosystems but are difficult to study directly; hence, beaks recovered from predator stomachs are critical to further understand their distribution and ecology. Cephalopod […]

Variability in Overwinter Antarctic Krill Transport Pathways and Connectivity in the South-West Atlantic Sector of the Southern Ocean
Read more of: Variability in Overwinter Antarctic Krill Transport Pathways and Connectivity in the South-West Atlantic Sector of the Southern OceanAntarctic krill are central to the Southern Ocean ecosystem and support a commercial fishery. Late larval stages of Antarctic krill depend on sea ice for food and shelter during winter. […]

Molecular mechanisms and energetic costs of recovery from freezing in the polyextremophile midge, Belgica antarctica
Read more of: Molecular mechanisms and energetic costs of recovery from freezing in the polyextremophile midge, Belgica antarcticaExtracellular freezing challenges insects in several ways, including mechanical damage from ice crystals, exposure to stressful levels of cold and cellular dehydration. While stress-response mechanisms activated during and immediately after […]

Reconstructing the historical wintering destinations of seabirds using stable isotope analyses of museum specimens
Read more of: Reconstructing the historical wintering destinations of seabirds using stable isotope analyses of museum specimensStable isotope analyses of museum specimens provide an opportunity to examine long-term changes in avian migration strategies. Here, we determined stable isotopes of carbon (δ13C) and nitrogen (δ15N) in body […]

The giant Antarctic amphipod Paraceradocus miersi will not fare well if freshening continues in the Southern Ocean
Read more of: The giant Antarctic amphipod Paraceradocus miersi will not fare well if freshening continues in the Southern OceanSea water provides a stable environment for marine animals. Most oceanic invertebrates have body fluids similar in ionic composition to sea water. However, Antarctic coastal ecosystems are increasingly exposed to […]

Reply to: Antarctic greening is constrained by biology and requires field validation
Read more of: Reply to: Antarctic greening is constrained by biology and requires field validationBokhorst et al.’s Matters Arising paper continues an important conversation around how vegetation change is detected and interpreted in data-sparse and logistically challenging regions such as Antarctica. In our study […]

Mapping snow on northern winter roads: a dual-frequency polarimetric radar approach for snow characterization over land, lake and sea ice
Read more of: Mapping snow on northern winter roads: a dual-frequency polarimetric radar approach for snow characterization over land, lake and sea iceWinter roads are lifelines for remote northern communities. Built over land, lakes, rivers, and sea ice, these travel routes are increasingly vulnerable to warming temperatures and variable precipitation. To ensure […]
