...Simon Bahrndorff; Jannik M. S. Lauritzen; Mathias H. Sørensen; Natasja K. Noer; Torsten N. Kristensen ABSTRACT Terrestrial arthropods in the Arctic and Antarctic are exposed to extreme and variable temperatures, and climate change is predicted to be especially pronounced in these regions. Available...

...Arnoldus Schytte Blix ABSTRACT This Review presents a broad overview of adaptations of truly Arctic and Antarctic mammals and birds to the challenges of polar life. The polar environment may be characterized by grisly cold, scarcity of food and darkness in winter, and lush conditions and continuous...

... does the Antarctic scallop, Adamussium colbecki , cope with the cold? Its shell mass is substantially reduced relative to that of temperate and tropical scallops, but this potential advantage is more than offset by a drastic reduction in adductor-muscle mass. By contrast, A. colbecki 's abductin...

... decade, much headway has been made in unravelling the variety of olfactory foraging strategies that Antarctic species employ, and it is becoming clearer that olfaction plays a key role in foraging, particularly for burrow nesting species. Now we are beginning to explore how these behaviours develop...

...D. A. Wharton; I. M. Brown ABSTRACT When free of surface water in air or liquid paraffin, the antarctic nematode Panagrolaimus davidi is freezing intolerant but avoids freezing by supercooling. Survival of long-term exposure is enhanced by sub-zero temperatures compared with controls maintained...

...J. S. Gibson; J. C. Ellory ABSTRACT All Antarctic fish studied so far show two adaptive strategies to life at sub-zero water temperatures; antifreeze glycoproteins, which act non-colligatively to inhibit ice propagation ( DeVries, 1983 ), and elevated plasma electrolyte levels (150–200mosmolI −1...
