The feeding mechanism of Yoldia (= Aequiyoldia) eightsi (Courthouy)
Read more of: The feeding mechanism of Yoldia (= Aequiyoldia) eightsi (Courthouy)The protobranch bivalve mollusc Yoldia eightsi Courthouy is both a deposit feeder (on mud) and a suspension feeder (on diatoms in the ventilatory streams, which are trapped on the ctenidia). […]

Observations on microbial activity in a seasonally anoxic, nutrient-enriched maritime Antarctic lake
Read more of: Observations on microbial activity in a seasonally anoxic, nutrient-enriched maritime Antarctic lakeAmos Lake is a shallow, permanently cold, maritime Antarctic lake which is almost totally anoxic for much of the 9 month period of winter ice cover each year. The lake […]

Food and feeding ecology of Wilson’s storm petrel Oceanites oceanicusat South Georgia
Read more of: Food and feeding ecology of Wilson’s storm petrel Oceanites oceanicusat South GeorgiaAt South Georgia, the diet of Wilson’s storm petrel was studied using the regurgitates of adults arriving to feed chicks. Feeding frequency and meal size were estimated by weighing chicks […]

Intraspecific allometry of neonatal size in the Antarctic fur sea (Arctocephalus galapagoensis)
Read more of: Intraspecific allometry of neonatal size in the Antarctic fur sea (Arctocephalus galapagoensis)Intraspecific allometry of pup mass as a function of maternal mass was analysed in Antarctic fur seals (Arctocephalus gazella), a highly dimorphic species. The allometric exponent was 0.6, much lower […]

Use of cloacal sexing techniques in mark-recapture estimates of breeding population size in Wilson’s stormpetrel Oceanites oceanicus at South Georgia
Read more of: Use of cloacal sexing techniques in mark-recapture estimates of breeding population size in Wilson’s stormpetrel Oceanites oceanicus at South GeorgiaMany stormpetrel species breed in habitats where their populations cannot be estimated by direct counts of burrows or birds; mark-recapture experiments have been confounded by the presence of many wandering […]
