Knowledge of the trophic ecology and interactions of marine top predators is fundamental for understanding community structure and dynamics as well as ecosystem function. This study provides the first baseline information on the trophic ecology of elasmobranchs caught in artisanal fisheries from south-western Madagascar.
Terrestrial runoff and sedimentation have been implicated in a variety of impacts on scleractinian corals. However, despite accumulating evidence, little work has been done to investigate their influence on coral disease development. This study examined the role that river runoff and the associated sedimentation could play in affecting the prevalence of the coral disease “white syndrome” in SW Madagascar.
Coral bleaching events vary in severity, however, to date, the hierarchy of susceptibility to bleaching among coral taxa has been consistent over a broad geographic range and among bleaching episodes. Here we examine the extent of spatial and temporal variation in thermal tolerance among scleractinian coral taxa and between locations during the 2010 thermally induced, large-scale bleaching event in South East Asia.
Tropical coastal ecosystems are the home and livelihood of hundreds of millions of people around the world. The effects of climate change on coastal ecosystems, such as coral bleaching, destruction from storms, and erosion from heavy rain, can harm these livelihoods. In the coastal regions of Madagascar, people rely heavily on fishing for their daily food and income. Blue Ventures aims to strengthen the resiliency of coastal ecosystems and communities in Madagascar and Belize through marine conservation initiatives and socio-economic programs that help local fishermen to respond and adapt to actual and anticipated climatic effects.
A monitoring programme was established in order to support community based seaweed farming in south-west Madagascar by providing scientific information on the effects of physico-chemical and health factors influencing the growth of Kappaphycus alvarezii(cottonii).
