  2. 16. The Invasion of the Zebra Mussel - Effects on Phytoplankton Community Structure and Ecosystem Function

    Author : Rahmat Naddafi; Kurt Pettersson; Peter Eklöv; Willem Goedkoop; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invasive species; Zebra mussel; Invasion success; Selective feeding; Non-lethal effects of predator; Seston stoichiometry; Delayed fluorescence excitation spectroscopy; Phytoplankton dynamics; Trait-mediated indirect interaction; Ecosystem function;

    Abstract : Biological invasion has become a major threat to economy, ecology, global biodiversity and ecosystem function of aquatic ecosystems. The main aim of the thesis was to study the effects of the zebra mussel (Dreissena polymorpha), a versatile invasive species, on phytoplankton dynamics and ecosystem function of lakes. READ MORE

  4. 17. The role of sediments in the biogeochemical cycles of nutrients in the Gulf of Riga

    Author : Juris Aigars; Matti Perttilä; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Abstract : The sediment biogeochemistry of C, N, P and biologic silica (BSi) plays an important role in cycling of these elements in aquatic ecosystems. In shallow coastal and estuarine systems, water-sediment nutrient dynamics can influence biological processes (e.g., primary production) in overlying waters. READ MORE

  5. 18. Shallow water carbonate basin of the Zanzibar channel, Tanzania

    Author : Yohanna W Shaghude; Birger Larsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; allmän och historisk geologi; General and Historical Geology;

    Abstract : The shallow water carbonate basin of the Zanzibar channel, Tanzania, has been investigated. This study discusses and describes the sea bottom topographic features, sediment composition, major characteristics of sediment distribution, provenance of sediments, and the depositional settings of the sediments .
