  1. 1. Estrogen receptor and multixenobiotic resistance genes in freshwater fish and snails: identification and expression analysis after pharmaceutical exposure

    University dissertation from Lund University, Faculty of Science, Center for Environmental and Climate Research

    Author : Cecilia Hultin; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; EE2; NSAID; estrogen receptor; oestrogen receptor; multixenobiotic resistance; fish; gastropods;

    Abstract : Pharmaceuticals are today released into aquatic environments where they can interfere with organisms' biological processes.The general research objective was to analyze how aquatic freshwater organisms are affected by exposure to pharmaceuticals that are categorized by the EU as potential risk factors to the environment (i.e. READ MORE

  2. 2. Pollinators and Insect Pollination in Changing Agricultural Landscapes

    University dissertation from Lund University, Faculty of Science, Centre for Environmental and Climate Research

    Author : Lina Herbertsson; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017-10]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollinators; pollination; agri-environment schemes; beekeeping; oilseed rape; sown flower strips; agri-environment measures;

    Abstract : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. READ MORE

  3. 3. Climate Science for Policy? The knowledge politics of the IPCC after Copenhagen

    University dissertation from Media-Tryck, Lund University, Sweden

    Author : Jasmine Livingston; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018-11]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; science; politics; IPCC; knowledge; performance;

    Abstract : The rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. READ MORE

  4. 4. Small biotopes: Landscape and management effects on pollinators

    University dissertation from Centre for Environmental and Climate Research (CEC) and Department of Biology, Faculty of Science, Lund University

    Author : Annika Söderman; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agri-environmnetal scheme; management; agriculture; landscape complexity; heterogeneity; landscape scale; mall biotopes; field boundaries; pollinating insects; pollination; bumblebees; solitary bees; hoverflies;

    Abstract : The intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. READ MORE

  5. 5. Dynamic modelling of the forest ecosystem: Incorporation of the phosphorus cycle

    University dissertation from Lund University, Faculty of Science, Center for Environmental and Climate Research

    Author : Lin Yu; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic modeling; forest ecosystem; phosphorus cycle;

    Abstract : The forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an increase in global temperature and extreme events such as storms.
