1. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling
Sammanfattning : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. LÄS MER
2. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS
Sammanfattning : 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). LÄS MER
3. Predictions Within and Across Aquatic Systems using Statistical Methods and Models
Sammanfattning : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. LÄS MER
