    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyanobacteria; nitrogenase activity; diazotrophs; seagrass; western Indian ocean; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : 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.

  4. 2. Seagrasses and their epiphytes : Characterization of abundance and productivity in tropical seagrass beds

    Author : Jacqueline Uku; Mats Björk; Beatriz Diez; Evamaria Koch; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seagrass; epiphytes; cyanobacteria; prokaryotes; diversity; productivity; carbon utilization; buffer sensitivity; Biology; Biologi;

    Abstract : Seagrass beds cover large intertidal and subtidal areas in coastal zones around the world and they are subjected to a wide variety of anthropogenic influences, such as nutrient enrichment due to sewage seepage. This study was undertaken to address specific questions focusing on whether near shore tropical seagrasses that receive a constant influx of groundwater nutrient inputs, would exhibit a higher productivity and to what extent epiphytic algae reflect the impacts of nutrient inputs.
