    Sammanfattning : Collecting sea cucumbers to supply the high value Chinese dried seafood market is a livelihood activity available to many people in the Western Indian Ocean (WIO), making it an important part of local economies. These fisheries are generally not successfully managed and tropical sea cucumber fisheries show continuing signs of decline. LÄS MER

  4. 4. Genetic variability and nitrogenase activity of cyanobacterial communities associated with tropical seagrass meadows (western Indian Ocean)

    Författare :Mariam Hamisi; Birgitta Bergman; Thomas Lyimo; Beatriz Díez; Lucas Stal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; nitrogenase activity; diazotrophs; seagrass; western Indian ocean; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Tropical seagrass ecosystems are highly productive and important for sustaining marine life and associated coastal societies. In this study, the diversity and role of nitrogen-fixing cyanobacteria associated with five common seagrass genera in coastal regions of the western Indian Ocean (WIO; Tanzania) were examined, as well as the impact of anthropogenic activities.

  5. 5. Systematics and Biogeography of Western Indian Ocean Region Rubiaceae : examples from Danaideae, Hymenodictyeae, and Naucleeae

    Författare :Åsa Krüger; Sylvain Razafimandimbison; Mary Endress; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; växtsystematik; Plant Systematics;

    Sammanfattning : This thesis focuses on the systematics and biogeography of the tribes Danaideae, Hymenodictyeae, and Naucleeae in the angiosperm family Rubiaceae (coffee family), with a special interest in the Western Indian Ocean region (WIOR). The levels of endemism in the WIOR are remarkably high and Madagascar is the largest island surrounded by three main archipelagos with islands of various age and size. LÄS MER
