  2. 1. Ecology of freshwater mussels in disturbed environments

    Author : Martin Österling; Larry Greenberg; Björn Arvidsson; David Strayer; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Unionoida; Margaritifera margaritifera; Dreissena; Salmo trutta; habitat degradation; turbidity; sedimentation; recruitment; conservation.; Biology; Biologi; Biology; Biologi;

    Abstract : The number of species extinctions is increasing at an alarming rate. Long-lived freshwater mussels of the order Unionoida, which include a parasitic stage on a host fish, are highly threatened. Habitat degradation by turbidity and sedimentation is thought to be one major reason for their decline. READ MORE

  4. 2. Light conditions in seasonally ice-covered waters : within the Baltic Sea region

    Author : Elina Kari; Susanne Kratzer; Matti Leppäranta; Monika Winder; Tiit Kutser; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seasonal sea ice; Fast ice; Drift ice; Phytoplankton spring bloom; Under-ice plume; Turbidity; Suspended particulate matter; Chlorophyll; Coloured dissolved organic matter; Baltic Sea; Marine Ecology; marin ekologi;

    Abstract : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. READ MORE

  5. 3. Sex in Murky Waters : Anthropogenic Disturbance of Sexual Selection in Pipefish

    Author : Josefin Sundin; Anders Berglund; Gunilla Rosenqvist; Bob Wong; Uppsala universitet; []
    Keywords : Mating system; Mate choice; Courtship; Eutrophication; Turbidity; Hypoxia; Ocean acidification; Syngnathidae; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Animals experience variation in their environment because of natural changes. However, due to anthropogenic disturbance, the speed and severity of these changes have recently increased. This thesis investigates how reproductive behaviours may be affected by human induced environmental change. READ MORE

  6. 4. Remote sensing in optically complex waters : water quality assessment using MERIS data

    Author : José M. Beltrán-Abaunza; Susanne Kratzer; Carsten Brockmann; Samantha Lavender; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ocean Colour; MERIS; Baltic Sea; Bio-optics; water quality; Chlorophyll; Turbidity; SPM; Himmerfjärden; Remote Sensing; Marine Ecology; marin ekologi;

    Abstract : This PhD study focusses on the use of MEdium Resolution Imaging Spectrometer (MERIS) data for reliable and quantitative water-quality assessment of optically-complex waters (lake, brackish and coastal waters). The thesis is divided into two parts: A. READ MORE

  7. 5. Loss Minimisation in Dynamic Food Processes

    Author : Marcus Henningsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

    Abstract : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. READ MORE
