1. Herbivores influence nutrient cycling and plant nutrient uptake : insights from tundra ecosystems
Abstract : Reindeer appear to have strong positive effects on plant productivity and nutrient cycling in strongly nutrient-limited ecosystems. While the direct effects of grazing on vegetation composition have been intensively studied, much less is known about the indirect effect of grazing on plant-soil interactions. READ MORE

2. The Vertical Distribution of Roots, Mycorrhizal Mycelia and Nutrient Acquisition in Mature Forest Trees
Abstract : The vertical distribution of the nutrient uptake of Norway spruce (Picea abies (L.) Karst.), European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L. READ MORE

3. Integrative physiology as a tool towards good animal welfare and sustainability in aquaculture: Focus on intestinal function and health
Abstract : The human population is growing, and the world’s leaders are trying to provide humans with food resources and at the same time setting goals promoting sustainable food production. This means that we need to find new food sources that are not in conflict with future generations’ right to a world without hunger and environmental destruction. READ MORE

4. Influence of water conditions on growth and mineral nutrient uptake of native plants on clacareous soil
Abstract : The studies presented in Papers I to IV illustrate the importance of soil moisture in soil solution chemistry and response of native plants to the changes induced by change in moisture regime. With the help of glasshouse experiments I tried to study the influence of different treatments of soil moisture conditions on the mineral uptake by native plants of calcareous soil. READ MORE

5. Phytoplankton succession and algal nutrient kinetics in eutrophic brackish water environments
Abstract : This thesis has been concerned with studying the effects of pollution on aquatic ecosystems with the main emphasis on investigating the phytoplankton succession in the brackish bay of Brunnsviken after sewage diversion.The causes of the observed changes have been investigated through enrichment experiments with phytoplankton in batch cultures and in studies of the nutrient uptake kinetics of Enteromorpha compressa.
