The role of atmospheric circulation patterns in driving recent changes in indices of extreme seasonal precipitation across Arctic Fennoscandia
Read more of: The role of atmospheric circulation patterns in driving recent changes in indices of extreme seasonal precipitation across Arctic FennoscandiaExtreme precipitation events (EPEs) have a major impact across Arctic Fennoscandia (AF). Here we examine the spatial variability of seasonal 50-year trends in three EPEs across AF for 1968–2017, using […]

Trade-off between aerobic performance and egg production in migratory macaroni penguins
Read more of: Trade-off between aerobic performance and egg production in migratory macaroni penguinsWhen successive stages of an organism’s life-history overlap, conflicts and trade-offs can emerge due to competition among physiological pathways. For example, long periods of sustained locomotion in migrating birds are […]

Antarctic geothermal heat flow: future research directions
Read more of: Antarctic geothermal heat flow: future research directionsAntarctic geothermal heat flow (GHF) affects the ice sheet temperature, determining how it slides and internally deforms, as well as the rheological behaviour of the lithosphere. However, GHF remains poorly […]

Determinants of genetic variation across eco-evolutionary scales in pinnipeds
Read more of: Determinants of genetic variation across eco-evolutionary scales in pinnipedsThe effective size of a population (Ne), which determines its level of neutral variability, is a key evolutionary parameter. Ne can substantially depart from census sizes of present-day breeding populations […]

Integrative description of a new Dactylobiotus (Eutardigrada: Parachela) from Antarctica that reveals an intraspecific variation in tardigrade egg morphology
Read more of: Integrative description of a new Dactylobiotus (Eutardigrada: Parachela) from Antarctica that reveals an intraspecific variation in tardigrade egg morphologyTardigrades constitute one of the most important group in the challenging Antarctic terrestrial ecosystem. Living in various habitats, tardigrades play major roles as consumers and decomposers in the trophic networks […]

A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID)
Read more of: A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID)The paleoclimate community has an interest in distributed subglacial bedrock sampling but, while capable drill systems do exist, they are often incompatible with Twin Otter logistics. To address this issue, […]
