Dynamic global vegetation models are key tools for interpreting and forecasting the responses of terrestrial ecosystems to climatic variation and other drivers. They estimate plant growth as the outcome of […]
The glacial history of the westernmost Weddell Sea sector of Antarctica since the Last Glacial Maximum is virtually unknown, and yet it has been identified as critical for improving reliability […]
The Weddell Gyre (WG) is one of the main oceanographic features of the Southern Ocean south of the Antarctic Circumpolar Current which plays an influential role in global ocean circulation […]
There is much recent evidence that prolactin is an important influence on parental and incubatory behaviour in birds. In this study prolactin was measured at various stages of the breeding […]
The responses of phytoplankton populations to seasonal changes in radiation flux in two Antarctic lakes with extensive winter ice-cover are described. A phytoplankton capable of photosynthesis was found throughout the […]
Water-soluble and ethanol-soluble carbohydrates were extracted from leaves, shoots, roots, rhizomes and flowers ofParodiochloa flabellata (Lam.) Rasp. (=Poa flabellata (Lam.) Hook f.) throughout a growing season. Very high levels of […]
Round Island (19°51’S, 57°47’E), an uninhabited volcanic islet lying 14 miles NNE of the Mauritian mainland, provides locally important breeding grounds for four species of seabirds; the Trindade Petrel Pterodroma […]
Ozone photochemistry over Antarctica in summer has been examined using a 1‐D model. With diffusive transport alone, the predicted ozone decay rates from the December (summer) solstice to the March […]
