Diet of the squid Loligo forbesi Steenstrup (Cephalopoda: Loliginidae) in Irish waters
Read more of: Diet of the squid Loligo forbesi Steenstrup (Cephalopoda: Loliginidae) in Irish watersStomach contents of Loligo forbesi obtained from commercial landings and research cruises in Irish waters and the Irish Sea were examined. A total of 62.3% of stomachs were empty. Fish […]

Biochemical composition in relation to the energetics of growth and sexual maturation in the ommastrephid squid Illex argentinus
Read more of: Biochemical composition in relation to the energetics of growth and sexual maturation in the ommastrephid squid Illex argentinusThe proximate (protein, lipid, carbohydrate and ash) and elemental (C, H, N and P) composition of the major tissues were measured for 18 male and 51 female Illex argentinus sampled […]

Nitrogen excretion in the Antarctic limpet Nacella concinna (Strebel, 1908)
Read more of: Nitrogen excretion in the Antarctic limpet Nacella concinna (Strebel, 1908)Excretion of ammonia, urea and primary amines (assayed as fluorescamine-positive substances, FPS) was measured in the Antarctic limpet Nacella concinna. The mean contributions to overall excretion rate were 89% ammonia, […]

Effects of feeding and starvation on the metabolic rate of the necrophagous Antarctic amphipod Waldeckia obesa (Chevreux, 1905)
Read more of: Effects of feeding and starvation on the metabolic rate of the necrophagous Antarctic amphipod Waldeckia obesa (Chevreux, 1905)The marked seasonality of high latitude marine ecosystems means that the relationship between nutrition and metabolism is of particular interest, for many polar organisms must survive long periods without food. […]

Foraging behaviour of Antarctic fur seals during periods of contrasting prey abundance
Read more of: Foraging behaviour of Antarctic fur seals during periods of contrasting prey abundance1. Foraging behaviour of Antarctic fur seals rearing pups at Bird Island, South Georgia, was assessed using at-sea activity patterns measured by electronic time-depth recorders. Information was obtained for a […]

Thermal adaptation in the Arctic collembolan Onychiurus arcticus (Tullberg)
Read more of: Thermal adaptation in the Arctic collembolan Onychiurus arcticus (Tullberg)Ecophysiological characteristics, including survival at high and low temperatures, locomotory activity at sub-zero temperatures, supercooling ability and oxygen consumption rates, were investigated for the Arctic springtail Onychiurus arcticus (Tullberg) (Collembola, […]
