1. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients
Sammanfattning : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. LÄS MER
2. Biomass and Nutrient Status of Benthic Algae in Lakes
Sammanfattning : For a complete picture of the lake ecosystem, it is necessary to understand the mechanisms regulating biomass and nutrient status (nutrient limitation, optimal supply, or surplus) of benthic algae, which are important primary producers and a food resource for grazers. This thesis gives an overview of the natural variation of benthic algae at different scales of space and time and on different substrates, and unravels some of the underlying factors. LÄS MER
