  2. 1. Climate Effects on Phytoplankton Biomass and Functional Groups

    Author : Hampus Markensten; Donald Pierson; Kurt Pettersson; Bengt Boström; Colin Reynolds; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Climate change; phytoplankton; chlorophyll a; Lake Mälaren; Galten; PROTBAS; numerical modeling; water quality; succession; shallow lake; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Future climate in temperate regions is projected to get warmer and in many cases wetter. This poses questions about how phytoplankton in our lakes will respond. READ MORE

  4. 2. Climate Change Impacts on the Catchment Contribution to Lake Water Quantity and Quality

    Author : Karen Moore; Kurt Pettersson; Donald Pierson; Timothy Kratz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; water quality modelling; Lake Mälaren; GWLF; nutrient transport;

    Abstract : A key question related to climate change projections is how will aquatic systems respond to changes in variables such as temperature and precipitation? This thesis uses GWLF, a simple catchment scale model to explore potential impacts of climate change on water quantity and quality.River discharge and nutrient loads were modelled for several warmer world scenarios.

  5. 3. Predictive Modeling of Lake Eutrophication

    Author : Jan Mikael Malmaeus; Lars Håkanson; Kurt Pettersson; Jürg Bloesch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; mechanistic model; phosphorus; LEEDS; suspended particulate matter; settling velocity; sedimentation; accumulation sediments; burial; diffusion; climate scenario; Erken; Balaton; Kinneret; Batorino; Miastro; Naroch; Galten; Ekoln; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : This thesis presents predictive models for important variables concerning eutrophication effects in lakes. The keystone is a dynamic phosphorus model based on ordinary differential equations. READ MORE

  6. 4. Underwater Worlds : An Ethnography of Waste, Pollution, and Marine Life

    Author : Rasmus Rodineliussen; Bengt Karlsson; Helena Wulff; Marianne Lien; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aquabiopolitics; Lake Mälaren; Marine Life; Pollution; Relations; Science; Social Media; Stockholm; The Baltic Sea; Time; Trash Diving; Violence; Visibility; Waste; Water; Social Anthropology; socialantropologi;

    Abstract : In this dissertation, I investigate relations between humans, waste, pollution, and marine life. I introduce the concept of Aquabiopolitics as a means to understand how humans govern life in water in order to enrich human life on land. READ MORE

  7. 5. Eel migration - results from tagging studies with relevance to management

    Author : Niklas B. Sjöberg; Sture Hansson; Håkan Wickström; Erik Petersson; Alan Walker; Stockholms universitet; []
