Temporal changes in biomass specific photosynthesis during the summer: regulation by environmental factors and the importance of phytoplankton succession

Temporal variations in biomass-specific photosynthesis were studied in Erken lake in central Sweden during summer stratification and related to algal adaptation to light, temperature and available nutrients. The rates of light-limited and light-saturated photosynthesis per unit chlorophyll-a showed...

Description
Summary:Temporal variations in biomass-specific photosynthesis were studied in Erken lake in central Sweden during summer stratification and related to algal adaptation to light, temperature and available nutrients. The rates of light-limited and light-saturated photosynthesis per unit chlorophyll-a showed distinct and similar temporal trends in each of 3 years. Seasonal trends were particularly prominent for light-saturated photosynthesis which increased in value for several weeks following the onset of thermal stratification before declining in the presence of the colonial blue-green alga Gloeotrichia echinulata.
