  2. 6. Damsel in distress – metabolomics as a novel tool to investigate the effects of wastewater exposure on damselfly larvae

    Author : Jana Späth; Malin L. Nording; Jerker Fick; Stina Jansson; Tuulia Hyötyläinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomarkers; ecotoxicology; invertebrates; GC-MS; LC-MS; LC-MS MS; metabolomics; micropollutants; pharmaceuticals; risk assessment; ekotoxikologi; Ecotoxicology; Analytical Chemistry; analytisk kemi;

    Abstract : Aquatic organisms, such as aquatic invertebrates, are exposed to anthropogenic pollutants through their environment. These pollutants, despite their low levels, can adversely affect exposed individuals or even entire ecosystems, especially when present in complex mixtures. READ MORE

  4. 7. Coping with environmental stress : from the individual and population perspective

    Author : Johanna Gardeström; Michael Tedengren; Tina Elfwing; Mats Grahn; Gary Carvalho; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental stress; Genetic diversity; Multi-level approach; Invertebrates; Marine ecology; Marin ekologi; Systems Ecology; systemekologi;

    Abstract : Natural stress and disturbances are important factors affecting the structure and function of ecosystems. However the magnitude of stress has escalated due to anthropogenic activities. Environmental monitoring and toxicity assessments try to protect ecosystems from unwanted human alterations. READ MORE

  5. 8. Phytobenthic communities in the Baltic Sea - seasonal patterns in settlement and succession

    Author : Susanne Qvarfordt; Hans Kautsky; Lena Kautsky; Hendrik Schubert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Succession; settlement; recruitment; phytobenthos; macroalgae; invertebrates; Baltic Sea; community; Biology; Biologi;

    Abstract : Seasonal changes in reproduction, recruitment, occurrence and growth of marine plant and animal species is a common phenomenon world-wide. This thesis investigates whether such seasonal changes could determine the succession in subtidal phytobenthic communities on free space in the Baltic Sea. READ MORE

  6. 9. Benthic cryptofauna and internal bioeroders on coral reefs

    Author : Helena Strömberg; Charlotta Kvarnemo; Pat Hutchings; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioerosion; cryptofauna; coral; invertebrates; damselfish; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : The cryptofauna of coral reefs may act as a food source for fish, while being grazers or predators themselves, and hence constitute an important group in the coral reef food web. In addition, the actively eroding taxa of the cryptofauna contribute to the decomposition and recirculation of calcium carbonate and are consequently essential for the rebuilding new coral.

  7. 10. From geography to genes: evolutionary perspectives on salinity tolerance in the brackish water barnacle Balanus improvisus

    Author : Anna-Lisa Wrange; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental change; salinity; marine; invertebrates; evolution; plasticity; population genetics; functional genomics; barnacle; osmoregulation;

    Abstract : How species respond to changes in their environment is a fundamental question in biology. This has become an increasingly important issue as anthropogenic effects of climate change and biological invasions have major impacts on marine ecosystems worldwide. READ MORE
