The Southern Ocean is a large‐scale, relatively homogeneous upwelling ecosystem whose
phytoplankton apparently grows suboptimally over much of its area. By contrast there is a …

Summary The 17 lakes on Signy Island, South Orkney Islands, provide examples of most
lake types found in the maritime Antarctic. Continuous monitoring of physico-chemical …

Three distinct population strategies were observed within the summer algal plankton of Lake
Fryxell (Taylor Valley, South Victoria Land, 77° 35'S, 163° 15'E). Phytoplankton immediately …

The ecology of the phytoplankton of Heywood Lake, Signy Island, South Orkney Islands,
Antarctica was investigated during 1969–72. The lake, which is ice‐covered for 8–10 …

Seasonal changes in nutrient concentrations, phytoplankton biomass and nutritional state
were followed in two contrasting Antarctic lakes. Oligotrophic Sombre Lake receives little …

Zooplankton and benthic invertebrates are important components of polar lakes and often
form the highest trophic level in the aquatic food web. Their biodiversity decreases towards …

The relationships of vertical profiles of phytoplankton photosynthesis to under-water light
were studied at 23 stations in the South Scotia Sea and Bransfield Strait. On 3 occasions …

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 …

This paper is a review of the effects of nutrient supply, light regime, and temperature on algal
growth in polar regimes. Blooms are formed mainly in spring or summer when the supply of …
