Modelling reproductive effort in sub-and maritime Antarctic mosses
Read more of: Modelling reproductive effort in sub-and maritime Antarctic mossesA 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. […]

Photosynthesis and dark respiration in Antarctic mosses?an initial comparative study
Read more of: Photosynthesis and dark respiration in Antarctic mosses?an initial comparative studyRates 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 […]

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.
