  2. 2. Macroalgae in the Baltic Sea responses to low salinity and nutrient enrichment in Ceramium and Fucus

    University dissertation from Umeå : Ekologi och geovetenskap

    Author : Lena Bergström; Umeå universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; adaptation; asexual reproduction; Baltic Sea; Gulf of Bothnia; salinity; macroalgae; nutrients; sexual reproduction; stress; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.

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

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences

    Author : Elina Kari; Stockholms universitet.; [2018]

    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. 5. Studies on Baltic Sea mysids

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Martin Ogonowski; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mysids; hydroacoustics; Baltic Sea; abundance; stable isotopes; specific dynamic action SDA ; diel vertical migration; partial migration; trophic interactions; physiology; benthic-pelagic coupling; protein:DNA; C:N ratio; genetic structure; Marine Ecology; marin ekologi;

    Abstract : Mysid shrimps (Mysidacea, Crustacea) are efficient zooplanktivores in both marine and freshwater systems as well as lipid rich prey for many species of fish.  Although some efforts have been made to study the role of mysids in the Baltic Sea, very few studies have been carried out in recent time and there are still knowledge gaps regarding various aspects of mysid ecology.
