1. 1. Predictive Modelling of Aquatic Ecosystems at Different Scales using Mass Balances and GIS

   Författare :Andreas Gyllenhammar; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; scales; marine fish farms; rainbow trout; nutrients; suspended particulate matter; phosphorus; nitrogen; GIS; basin delineation; regionalisation; coastal areas; aquatic foodweb; fishing quotas; Baltic Sea; Archipelago Sea; Okavango Delta; Geovetenskap; Earth sciences; Geovetenskap;

   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
