2. 1. Managing Mangrove Ecosystem Services for Local Livelihoods and Adaptations in Tanzania

   Author : Baraka Nyangoko; Håkan Berg; Martin Gullström; Mwita Mangora; Mwanahija Shalli; Johan Hollander; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mangroves; ecosystem services; mangrove management; livelihoods; ecosystem-based adaptation; Tanzania; naturgeografi; Physical Geography;

   Abstract : Recognizing the importance of ecosystem services (ES) for peoples' livelihoods and well-being is important for decision-making processes on conservation. Mangrove ecosystems in Tanzania are protected by law, but they continue to be exposed to degradation and loss, and there is still limited information about the awareness, preferences, status and trends of the ES they provide.

4. 2. 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

5. 3. Coral Reef Habitats and Fish Connectivity : Implications for coastal management and fishery

   Author : Tove Lund Jörgensen; Michael Tedengren; Nick Graham; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic disturbance; coral reef habitat; fish community; coastal ecosystems; conservation management; spatial ecology; seascape perspective; holistic approach; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.

6. 4. 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. 5. 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
