2. 11. Colonised Coasts : Aquaculture and Emergy Flows in the World System: Cases from Sri Lanka and the Philippines

   Author : Daniel A. Bergquist; Lennart Strömquist; Clas Lindberg; Torbjörn Rydberg; Aida Aragao-Lagergren; Örjan Sjöberg; Uppsala universitet; []
   Keywords : Social and economic geography; Aquaculture; Capitalism; Socio-economic effects; Environmental effects; Benefit distribution; Sustainability; Sustainability assessment; Fairness; Development; Interdisciplinary; Transdisciplinary research; Geography; Emergy; World System Theory; General Systems Theory; Sustainable development; Sri Lanka; Philippines; Kulturgeografi;

   Abstract : This thesis conceives aquaculture as a transfer of resources within and between different parts of the world system. It is argued that due to inappropriate human-nature interactions, resources tend to flow from the South to the North, as a process of coastal colonisation. READ MORE

4. 12. Ecological connectivity in East African seascapes

   Author : Charlotte Berkström; Nils Kautsky; Susan S. Bell; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish; functional group; food-web interactions; nursery; coral; seagrass; mangrove; landscape ecology; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Coral reefs, seagrass beds and mangroves constitute a complex mosaic of habitats referred to as the tropical seascape. Great gaps exist in the knowledge of how these systems are interconnected. This thesis sets out to examine ecological connectivity, i.e. READ MORE

5. 13. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

   Author : Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

   Abstract : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. READ MORE

6. 14. Fish community patterns in Tanzanian mangrove creeks

   Author : Augustine Mwandya; Martin Gullström; Olof Lindén; Stockholms universitet; []
   Keywords : Mangrove ecosystems; fish assemblages; Mugil cephalus; population genetics; spatial and seasonal variability; human disturbance; East Africa; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zooekologi;

   Abstract : Human beings have exploited the biota of mangrove systems for centuries and fish continue to be one of the main products harvested from these habitats. The assumption of mangroves functioning as recruitment areas for juvenile fish from neighbouring habitats such as seagrass beds and coral reefs is a common argument for conservation and management of mangrove ecosystems.

7. 15. Nutrient Dynamics and Exchanges Between a Mangrove Forest and a Coastal Embayment: Chwaka Bay, Zanzibar

   Author : Salim Mohammed; Frank Dehairs; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

   Abstract : Nutrient dynamics and exchanges were studied in the Mapopwe Creek, a tidally dominated mangrove lined waterway, and a shallow lagoon in Chwaka Bay, Zanzibar, in order to assess whether there was any ecological coupling between the mangrove forest and adjacent ecosystems. In this study it was found that seasonal terrestrial input sources and benthic microalgal uptake strongly influenced the concentrations and distribution of dissolved nutrients in the system. READ MORE
