Snow surfaces in the polar regions have uniform reflecting properties over large areas. Slopes are usually low-in Antarctica, they rarely exceed 2/spl deg/ except in mountainous regions. Such low slopes […]
A comparison is made of the reproductive effort (RE), considered as the investment in sporophyte relative to gametophyte biomass, of eight species of moss occurring at sub-and maritime Antarctic sites. […]
Growth and mortality rates of three juvenile instars and adults of the oribatid mite Alaskozetes antarcticus were measured over a twelve month period using field enclosures m Its maritime Antarctic […]
Rates of dark respiration (DR), gross photosynthesis (GPS) and net photosynthesis (NPS) were investigated for 14 species of moss from a maritime Antarctic locality. The rates found were similar to […]
We examine some aspects of the performance of the United Kingdom Meteorological Office’s new climate model over Antarctica. Pressure and temperature fields are presented as a basic check on the […]
Stomach 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 […]
The 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 […]
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, […]
