Faecal egestion and ammonia excretion were measured in the Antarctic limpet Nacella concinna (Strebel, 1908) at Signy Island during the austral summer of 1986/87. Limpets were sampled from nearby shallow […]
The relationship between quasi-periodic VLF emissions and micropulsations is briefly reviewed, and then discussed with reference to an event recorded at Halley, Antarctica, on day 257 in 1986. VLF emissions […]
The age distribution of breeding female Antarctic fur seals at Bird Island, South Georgia, in 1988 was compared with the age distribution of a sample obtained in 1971–1973. The mean […]
Adult Antarctic fur seals (Arctocephalus gazella) were immobilized with Zoletil® (n= 172), ketamine (n= 30), ketamine mixed with diazepam (n= 23) and with ketamine mixed with xylazine (n= 45). Response […]
Dehydration experiments were conducted on individual Collembola at 0% relative humidity with the temperature ramped from 5 to 34°C at the rate of 0.5°C min−1. Continuous records of weight loss […]
1. Freezing was lethal in the eggs, larvae, pupae and adults of the blowflies Calliphora vicina R‐D. and Calliphora vomitoria (L.), but varying degrees of supercooling were found. 2. Cold […]
Arthropods, as poikilotherms, adapt to cold environments in a variety of ways that include extension of locomotory activity to low temperatures, enhancement of metabolic rate and maintenance of a positive […]
Distribution, size composition and behaviour of Euphausia superba were investigated in the northwestern Weddell Sea (59–63°S, 45–52°W) in October-November 1988 using RMT trawling, SCUBA diving and visual examination of the […]
