  1. 1. Physiological responses of marine and brackish Fucus vesiculosus L. with respect to salinity

    Author : Maria Gylle; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; acclimation; Bothnian Sea; compatible solutes; desiccation; fluorescence; F. vesiculosus; F. radicans; immunoblot; mannitol; photosynthesis; Rubisco; salinity; Algfysiologi; Biology; Biologi;

    Abstract : The intertidal brown alga Fucus vesiculosus L. is mainly a marine species (34 practical salinity units, psu), but the alga also grows in the sublittoral of the brackish Bothnian Sea (part of the Baltic Sea; 5 psu). READ MORE

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

    Author : Charlotta A Nygård; Nils Ekelund; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

    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

  4. 4. Trophic effects on the maintenance of biodiversity in the Fucus zone

    Author : Sonja Råberg; Lena Kautsky; Christer Brönmark; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; epiphytes; eutrophication; faunal assemblage; filamentous algae; Fucus radicans; Fucus vesiculosus; grazers; nutrient supply; Marine ecology; Marin ekologi; Plant Ecology; växtekologi;

    Abstract : Ecologically important macroalgae with large thalli and complex structures are threatened worldwide due to anthropogenic activities such as pollution. In the northern Baltic Sea the salinity is very low; the only large algae producing complex structural habitats found there are the fucoid species Fucus radicans and F. vesiculosus. READ MORE

  5. 5. Habitat-Forming Seaweeds in a Changing Climate

    Author : Alexandra Kinnby; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean acidification; Warming; Freshening; Temperature; Salinity; pH; pCO2; Fucus vesiculosus; Phlorotannins; Grazing; Tissue resilience; Macroalgae;

    Abstract : Climate change is an umbrella term encompassing some of the largest and most potent selective pressures currently acting on ecosystems. It can have diverse effects on marine systems; the most powerful of which are changes to salinity through altered patterns of precipitation and evaporation, temperature through increased global temperature, and pH through the dissolution of CO2 into seawater where it ultimately reacts with water to form carbonate (CO32-) and hydrogen ions (2H+).
