  1. 1. Seaweed in the tropical seascape : Importance, problems and potential

    Author : Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. READ MORE

  2. 2. Carbon sequestration processes in tropical seagrass beds

    Author : Liberatus Dominick Lyimo; Mats Björk; Martin Gullström; Mariam Hamis; Teresa Alcoverro; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Seagrass; Carbon sequestration; Carbon sink; Eutrophication; Productivity; Nitrous oxide; Methane; Greenhouse gases; Tropical; Eastern Africa; Plant Physiology; växtfysiologi;

    Abstract : Seagrass meadows may play a substantial role in climate change mitigation as they are capable to sequester and store substantial amounts of anthropogenic carbon in plant biomass and, more importantly, in their underlying sediments. In this PhD thesis, the carbon-burial potential was assessed by quantifying the amount of organic carbon stored in different seagrass meadows, each dominated by one of the four major seagrass species in the Western Indian Ocean region.

  3. 3. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems

    Author : Elisa Alonso Aller; Johan S Eklöf; Charlotte Berkström; Martin Gullström; Glenn Hyndes; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; coastal ecosystems; seagrass; marine protected areas; management; conservation; fish; herbivory; Western Indian Ocean; East Africa; tropical; Marine Ecology; marin ekologi;

    Abstract : Seagrass beds are highly productive coastal ecosystems that sustain a rich and diverse associated fauna and flora. Increasing anthropogenic pressures threaten seagrass ecosystems and have already led to major seagrass losses across the world. READ MORE

  4. 4. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

    Author : Myriam Mujawamariya; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide; Climate change; Drought; Elevation gradient; Photosynthesis; Respiration; Tropical montane forest; Tropical trees; Warming;

    Abstract : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.
