1. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS
Abstract : This thesis presents models applicable for aquatic ecosystems. Geographical Information Systems (GIS) form an important part of the thesis. The dynamic mass balance models focus on nutrient fluxes, biotic/abiotic interactions and operate on different temporal and spatial scales (site, local, regional and international). READ MORE

2. Element transport in marine coastal ecosystems – modelling general and element-specific mechanisms
Abstract : Understanding the behaviour of naturally-occurring and anthropogenically-derived radionuclides (isotopes) in the marine environment is important, because there is a need for their effective utilization either as in situ tracers or for industry, medical applications, the planning of waste-disposal facilities, and estimations of human and animal health risks. Radionuclides generally have the same chemical properties as their stable element analogues and thus show similar environmental behaviour and cycling to their stable counterparts. READ MORE

3. Impacts of global change on primary production in northern lakes
Abstract : Algae are primary producers, a major component of the aquatic foodweb, and changes in primary production affect aquatic ecology in general. Global changes such as warming, recovery of acidification and changes in land-use have caused warming and browning of northern lakes. READ MORE
