  2. 1. Benthic diatoms in the Gulf of Bothnia : Community analysis and diversity

    Author : Svenja Busse; Michael Sullivan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Baltic Sea; Biodiversity; Biomass; Community ecology; Diatoms; Multivariate analysis; Navicula; Phytobenthos; Salinity gradient; Scale; Size; Water movement; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Ecological Botany; Ekologisk botanik;

    Abstract : Benthic diatoms are valuable tools for biological monitoring and paleo-ecological reconstruction of past environmental conditions. This thesis aims at describing size-related properties of benthic diatoms and suggests that data assessment for community analysis can be improved by considering the importance of scale. READ MORE

  4. 2. Modelling spatial and temporal species distribution in the Baltic Sea phytobenthic zone

    Author : Antonia Nyström Sandman; Hans Kautsky; Martin Isaeus; Georg Martin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; species distribution modelling; niche; gradient; prediction; environmental factors; phytobenthos; scale; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

    Abstract : Statistical modelling is often used to relate the presence or abundance of species to environmental predictors, thereby providing a basis for predictive mapping of species or biodiversity. The variables included must thus be relevant and reflect actual changes in the environment. READ MORE

  5. 3. 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
