    Environmental Effects on the Distribution of Corallimorpharians in Tanzania
    (Royal Swedish Academy of Sciences, 2002) Muhando, Christopher A.; Kuguru, Baraka; Wagner, Gregory; Mbije, Nsajigwa; Öhman, Marcus
    This study examined the distribution and abundance of corallimorpharians (Cnidaria, Anthozoa) in Tanzania in relation to different aspects of the coral reef environment. Five reefs under varying degrees of human disturbance were investigated using the line intercept transect and point technique. Corallimorpharian growth and the composition of the substratum were quantified in different habitats within reefs: the inner and middle reef flat, the reef crest, and at the 2 and 4 m depths on the reef slope. Corallimorpharians occurred on all the reefs and 5 species were identified: Rhodactis rhodostoma, R. mussoides, Ricordea yuma, Actinodiscus unguja and A. nummiforme. R. rhodostoma was the dominant corallimorpharian at all sites. Within reefs, they had the highest densities in the shallow habitats. While R. rhodostoma occurred in all habitats, the other corallimorpharian species showed uneven distributions. Corallimorpharians ranked second, after scleractinian coral, in percent living cover. Results from this study suggested that corallimorpharians benefitted from disturbance compared with other sessile organisms. They preferred inhabiting areas with dead coral, rock and rubble whilst live coral was avoided. There was a positive relationship between percent cover of corallimorpharians and water turbidity and they dominated the more disturbed reefs, i.e. reefs that were affected by higher nutrient loads and fishing.

    Review of Literature for a Climate Vulnerability Assessment in the RUMAKI Seascape, Tanzania
    (2015-04) Tumbo, Madaka; Mangora, Mwita M.; Pauline, Noah M.; Kuguru, Baraka
    WWF’s Coastal East Africa Initiative (CEAI) is an umbrella programme that provides regional strategic support to the work of WWF country offices in Kenya, Tanzania and Mozambique. The CEAI was launched in 2010 and has a technical team based in Dar es Salaam. Priority areas of work include: v Natural resources governance in nine priorities landscapes & seascapes (see Fig.1.1 below) v Governance of Western Indian Ocean tuna fisheries v Fisheries certification, especially shrimp fisheries in Mozambique v Africa-China natural resources trade, especially timber v Climate change adaptation Within the CEAI, the climate change adaptation programme was initiated early in 2011 and aims to ensure that WWF’s conservation programme in coastal Eastern Africa recognizes and addresses the impacts of global climate change on priority ecosystems, and on communities that depend on them. In particular, during the period 2012 – 2015 the CEAI is supporting five priority landscapes to undertake climate change vulnerability assessments and to develop and implement climate change adaptation strategies, where possible integrated into existing or new natural resources management strategies and plans.
