2. 1. Geological development of the East African coastal basin of Tanzania

   Author : Samson Mpanda; Ole Veibaeck; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Geology; seismic methods; seismic stratigraphy; multichannel seismic recordings; tectonic development; Karoo; Mesozoic; Tertiary; East Africa; Tanzania; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

   Abstract : The East African coastal basin of Tanzania, which is characterised by an extensional tectonic style, is located along the passive continental margin of the western Indian Ocean. The present study is concerned with the Mafia Island and the Mafia Channel which together form a subbasin within the north-south elongated coastal sedimentary basin of Tanzania. READ MORE

4. 2. Pesticides in coastal Tanzania : Management, policy and concerns for human health and the environment

   Author : Nadja Stadlinger; Linda Kumblad; Anders Sjögren; Nils Kautsky; Kees Jansen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sub-Saharan Africa; agrochemicals; legislation; farmer education; hazards; subsidies; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : This thesis is the first major assessment of pesticide management in Zanzibar, Tanzania. It underlines the risks for human health and the environment that are likely under the current pesticide management regime. READ MORE

5. 3. Exploring the resilience in coral reefs

   Author : Jerker Lokrantz; Magnus Nyström; Morgan Pratchett; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coral Reefs; Resilience; Functional Groups; Vulnerability; Overfishing; Ecosystem Indicators; Tanzania; Zanzibar; Marine ecology; Marin ekologi; naturresurshushållning; Natural Resources Management;

   Abstract : Considering the unprecedented global decline of coral reefs concerns about their future existence are well-justified. Safeguarding ecological resilience (i.e. the capacity of ecosystems to absorb disturbance without changing their identity) has become a prime goal for management in order to combat further degradation of coral reefs.

6. 4. Patterns of fish larvae and zooplankton distribution in mangrove-seagrass seascapes of East Africa

   Author : Barnabas Alphonce Tarimo; Martin Gullström; Monika Winder; Mats Björk; Gunilla Rosenqvist; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fish larvae; zooplankton; population dynamics; community structure; environmental variables; seasonal variation; habitat use; mangroves; seagrass meadows; seascape connectivity; Tanzania; western Indian Ocean; marin ekologi; Marine Ecology;

   Abstract : Mangroves and seagrass meadows create coastal seascapes acting as breeding and nursery grounds for many fish species in tropical areas. Despite increased awareness on the role of these coastal habitats to fish, less knowledge is given to fish larvae distribution and population dynamics, limiting the understanding of major drivers of fish population dynamics and fisheries resources management, particularly in understudied regions such as the Western Indian Ocean.

7. 5. Anthropogenic Disturbances and Shifts in Tropical Seagrass Ecosystems

   Author : Johan S. Eklöf; Nils Kautsky; Patrik Rönnbäck; Teresa Alcoverro; Stockholms universitet; []
   Keywords : Aquaculture; feedback mechanisms; Kenya; management; overgrazing; regime shift; resilience; seagrass; seaweed farming; sea urchins; Tanzania; trophic cascades; Zanzibar; NATURAL SCIENCES; NATURVETENSKAP; Marine Ecotoxicology; marin ekotoxikologi;

   Abstract : Seagrasses constitute the basis for diverse and productive ecosystems worldwide. In East Africa, they provide important ecosystem services (e.g. fisheries) but are potentially threatened by increasing resource use and lack of enforced management regulations. READ MORE
