Variations in the rate of moulting and of faecal pellet production by Cryptopygus antarcticus (Willem), collected from Signy Island in the maritime Antarctic, were measured over temperatures of 0° to […]
Krill fishing in the Southern Ocean has raised in acute form the question of wildlife conservation in Antarctica: what will be the effect on the ecosystem? how much krill can […]
Cold environments impose several ecological and physiological constraints upon arthropods, including reduction of metabolic rate, locomotory activity, and feeding. These result in slow growth rates and extended life cycles. Additionally, […]
The main features of the cold hardiness strategies adopted by Antarctic terrestrial arthropods (principally Acari and Collembola) are reviewed. These include lethal low temperatures, chill-coma temperature, supercooling ability, cryoprotectants and […]
Bottom melting rates have been calculated for a large number of sites on George VI Ice Shelf from measurements of its kinematic behaviour. No simple explanation for the melt-rate pattern […]
