  2. 1. Climate change impacts on aquatic consumer communities

    Author : Shuntaro Koizumi; Pär Byström; Ryan Sponseller; Jonathan Shurin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; browning; aquatic consumers; zooplankton; benthic insects; fish; ecosystem experiment; environmental science; miljövetenskap;

    Abstract : Climate change represents a serious threat to aquatic ecosystems, with an increase in lake temperatures already observed that is expected to continue in the near future. Aside from the direct effects of warming, climate change is also partially responsible for the browning of lakes. READ MORE

  4. 2. Carbon Dioxide Supersaturation in Lakes – Causes, Consequences and Sensitivity to Climate Change

    Author : Sebastian Sobek; Lars J. Tranvik; Yves Prairie; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; carbon dioxide; boreal lakes; respiration; dissolved organic carbon; climate change; Biologi; Biology; Biologi;

    Abstract : The global carbon cycle is intimately linked with the earth’s climate system. Knowledge about carbon cycling in the biosphere is therefore crucial for predictions of climate change. READ MORE

  5. 3. 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.

  6. 4. Basin-scale change in water availability and water quality under intensified irrigated agriculture

    Author : Rebecka Törnqvist; Jerker Jarsjö; Marcel van der Perk; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Irrigation; Hydrology; Land-use change; Basin-scale; Central Asia; Aral Sea; Semi-arid; Return flow; Water saving; Health risk; Water quality; Surface water; Groundwater; Nitrogen; Attenuation; Recirculation; Climate change; Physical Geography; naturgeografi;

    Abstract : Changes in land use and water use can greatly impact the cycling of water and water-borne substances. Increased redistribution of river water to irrigated fields can cause enhanced evapotranspiration and decreased river discharge. READ MORE

  7. 5. 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
