  1. 1. Climate-induced changes : Its effects on plankton food webs from the Baltic Sea

    Författare :Claudia Romero-Oliva; Edna Graneli; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate-induced changes; temperature; acidification; marine food web; natural plankton community; spring; summer; Baltic Sea; Marine ecology; Marin ekologi; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : The Earth’s climate is determined different processes occurring in the atmosphere, land and ocean.Anthropogenic activities (mainly combustion of fossil fuels) have increased since the 1950’s, andthus the concentration of greenhouse gases that are warming up the planet. LÄS MER

  3. 2. Climatised Moves : Climate-induced Migration and the Politics of Environmental Discourse

    Författare :Giovanni Bettini; LUCSUS; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; migration; climate security; adaptation; resilience; post-politics;

    Sammanfattning : This work seeks to de-naturalise climate-induced migration (CM). Combining political ecology and post-foundational theories, I read CM as a construct that reifies a series of phenomena into an issue to be researched and governed. LÄS MER

  4. 3. Response of marine food webs to climate-induced changes in temperature and inflow of allochthonous organic matter

    Författare :Rickard Degerman; Agneta Andersson; Risto Lignell; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; bacterial production; mesocosm; food web efficiency; Baltic Sea;

    Sammanfattning : Global records of temperature show a warming trend both in the atmosphere and in the oceans. Current climate change scenarios indicate that global temperature will continue to increase in the future. The effects will however be very different in different geographic regions. LÄS MER

  5. 4. Climate-induced ecological change in subarctic lakes - Evidence from biological archives, long-term monitoring, and contemporary field studies

    Författare :Jenny Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Northern lakes have a unique flora and fauna and are sensitive ecosystems that experience rapid rates of change. Multiple environmental changes are currently affecting these lakes, including climate-induced oligotrophication, with nutrient levels decreasing in waters throughout the Scandinavian mountain range.

  7. 5. Influence of Human-induced Environmental Changes on the Physiology of the Harmful Benthic Marine Microalga Ostreopsis ovata

    Författare :Nayani K. Vidyarathna; Edna Granéli; Sandra Shumway; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ostreopsis ovata; benthic dinoflagellate; climate change; temperature increase; nutrient enrichment; acidification; physiology; cell growth; cell toxicity; carbohydrate accumulation; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : This thesis focus on the influence of human-induced environmental changes on the physiology of Ostreopsis ovata; a toxic, benthic dinoflagellate, which form blooms in tropical and temperate marine waters. O. LÄS MER
