This study employed H-1 NMR spectroscopy to assay the metabolome of the high Arctic freeze-tolerant dipteran larvae, Heleomyza borealis, after recovery from exposure to a range of sub-zero temperature treatments. […]
A technique for rapidly measuring non-lethal thermal tolerance traits in small insects and terrestrial arthropods of similar size is described. Single or multiple individuals are heated or cooled in an […]
In the maritime Antarctic, terrestrial arthropods have recourse to two strategies to mitigate low summer temperatures: (1) physiological plasticity and (2) avoidance via microhabitat insulation. This study investigated the interaction […]
Maturation to adulthood and successful reproduction in the Antarctic fairy shrimp, Branchinecta gaini, must be completed within a physiologically challenging temporal window of ca. 2.5 months in the southern Antarctic […]
The coastal ocean provides nutrients to the open ocean in accounts that are poorly quantified. We use an ocean biogeochemistry model to assess the importance of the coastal nutrient supply […]
Antarctic krill (Euphausia superba) is a keystone species in the southern ocean ecosystem where it is the main consumer of phytoplankton and constitutes the main food item of many higher […]
Tardigrada is a phylum closely allied with the arthropods. They are usually less than 0.5 mm in length, have four pairs of lobe-like legs and are either carnivorous or feed […]
Antarctic shallow-water and deep-sea echinoderms are known to have seasonal gametogenic cycles linked to seasonal pulses of phytodetritus produced in surface waters. We suggest that phytodetritus reaching the Antarctic continental […]
Antarctic Base personnel live for 3 months in winter with no natural sunlight. This project compared sleep, by actigraphy, during periods of increased exposure to white light or blue enriched […]
This manuscript was produced as an introduction to this publication emanating from CIAC ’09, the recent triennial symposium of the Cephalopod International Advisory Council. Given the importance of one of […]
