  2. 6. 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

    Author : A Maria Gylle; Nils GA Ekelund; Stefan Falk; Pauli Snoeijs; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bothnian Sea; brackish; brown algae; D1; 77 K fluorescence emission; Fucus vesiculosus; Fucus radicans; light-harvest antenna; mannitol; marine; NMR; Norwegian Sea; quantum yield; photosynthetic maximum capacity Pmax ; photosystem; PSI; PSII ; PsaA; Rubisco; salinity.; Biology; Biologi; Plant physiology; Växtfysiologi;

    Abstract : The in origin intertidal marine brown alga Fucus vesiculosus L. grow permanently sublittoral in the brackish Bothnian Sea, side by side with the recently discovered F. radicans L. Bergström et L. READ MORE

  5. 8. Ecophysiological responses of Baltic and Atlantic Fucus vesiculosus to environmental factors

    Author : Charlotta A Nygård; Nils Ekelund; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acclimation; Atlantic; Baltic Sea; Bothnian Sea; Cd; Fucus vesiculosus; growth; high PAR; Pb; photosynthesis; salinity; stress; UV-B; Biology; Biologi;

    Abstract : The Baltic Sea is a species-poor ecosystem where marine species coexist with freshwater species. The Baltic Sea offers low salinity, low content of inorganic carbon, long cold winters and no tides. READ MORE

  6. 9. Reproductive traits in euryhaline gobies: insights into physiology, adaptations and biological invasions

    Author : Leon Green; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sperm; Reproduction; Life-history Strategies; Local Adaptation; Fish; Invasion Biology; Salinity;

    Abstract : Organisms are adapted to reproduce in their specific environment by a range of different traits. For many animals, reproduction is tied to specific conditions, that trigger or enable the reproductive events. This thesis deals with traits associated with reproduction, their functions and interactions with the environment. READ MORE

  7. 10. DISCO - Drivers and Impacts of Coastal Ocean Acidification

    Author : Laurie Charrieau; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coastal ocean acidification; Foraminifera; Environmental changes; pH; Salinity;

    Abstract : Ocean acidification, mainly attributed to the increasing anthropogenic CO2 in the atmosphere, is characterised by a lowering pH together with a shift in the sea water carbonate chemistry toward lower concentration of carbonate ions. On the coasts, where the environmental variability is high due to natural and human impacts, ocean acidification mainly affects the frequency, magnitude, and duration of lower pH and lower calcium carbonate saturation events.
