The use of heart rate to estimate oxygen consumption of free-ranging black-browed albatrosses Diomedea melanophrys
Read more of: The use of heart rate to estimate oxygen consumption of free-ranging black-browed albatrosses Diomedea melanophrysHeart rates (fh) and rates of oxygen consumption (V(dot)O2) were measured in eight black-browed albatrosses (Diomedea melanophrys) when walking on a treadmill, with the aim of using fh to predict […]

Seasonal variation in the feeding activity of four species of Antarctic bryozoan in relation to environmental factors
Read more of: Seasonal variation in the feeding activity of four species of Antarctic bryozoan in relation to environmental factorsMany areas of the Antarctic continental shelf support rich communities of benthic suspension feeders, of which Bryozoa are frequently an important component. These communities inhabit an environment characterised by a […]
