Coral reefs and climate change in the Indian ocean : a case study of Watamu Marine National Park, Kenya and other Indian Ocean locationsCowburn, Benjamin January 2015 (has links)
Coral reefs are arguably the most threatened marine habitat because of multiple anthropogenic stressors degrading the health and resilience of these systems. In the past 20 years there have been increasing observations of mass coral bleaching and mortality associated with increasing water temperatures in the tropics. Reefs provide ecosystem services worth billions of dollars to people living in tropical coastal areas and are the architects of one of the most beautiful structures found on earth. Conserving these habitats is paramount, and conservation planning must contend with climate change along with local and regional stressors. In this thesis Watamu Marine National Park in Kenya is used as a case study of the current challenges facing the conservation of reefs in a warming world. The Western Indian Ocean suffered dramatic bleaching during 1998, which caused the mortality of 70% of Watamu's corals. Using datasets from the 1980s to present the historical trajectory of Watamu's reef community is presented. The current ecosystem resilience is assessed to suggest how this reef will respond to future climate stress. It appears that Watamu's coral community has remained in an altered state post-1998, which, based on its past thermal stress and current coral community, should be resistant to future bleaching. Watamu's resilience and reef health is compared with other locations in the Indian Ocean, including reefs in Kenya and the Maldives that bleached in 1998 and examples from Mozambique and Sumatra of reefs with little evidence of historical thermal stress. Resilience is a multi-faceted process with different major components and numerous interacting factors, which act synergistically on the reef community. Conservation options and opportunities are discussed for the 6 locations examined, using current resilience models and theory as a framework for identifying priority actions. Local and regional-scale human impacts on shallow marine habitats during the last 50 years has been dramatic, and with global-scale climate change as an additional major threat, the next 50 years will be critical for the future of reefs. The locations visited during this study showed encouraging signs of resilience to past thermal stress, with evidence to suggest that corals are acclimatising and/or adapting to increasing water temperatures. The future of reefs in locations like Watamu is uncertain. Better understanding of reef ecology, appropriate conservation techniques and ultimately greater public concern for reefs is required to ensure that there is a future for these ecosystems in the Indian Ocean.

Factors affecting the dynamics and regulation of coral-reef fish populationsWebster, Michael Scott 11 September 2001 (has links)
Ecologists have long questioned why fluctuating populations tend to persist
rather than go extinct. Populations that persist indefinitely are regulated by
mechanisms that cause demographic density dependence, which works to bound
fluctuation above zero. In a series of studies, I have sought to determine the processes
and mechanisms that regulate local populations of coral-reef fish. In the Exuma Keys,
Bahamas, fairy basslets (Gramma loreto) live in aggregations on the undersides of
coral-reef ledges. These aggregations often constitute local populations because
movement between aggregations is rare. The largest individuals occupy prime feeding
positions near the front of ledges and force smaller individuals remain near the back
where they have lower feeding rates. Based on these initial observations, I designed
two experimental studies of the demographic consequences of variation in basslet
density. In the first study, I manipulated the density of newly-settled fish to explore the
effects of high recruitment on population size. Populations with experimentally
elevated recruitment converged in density with unmanipulated populations, primarily
due to density-dependent mortality. I found no evidence that density dependence was
caused by intraspecific competition; rather it appeared to be due to a short-term
behavioral response by predators (aggregative and/or type 3 functional response). In a
second study, I manipulated the densities of adults among populations with a standard
average density of newly-settled fish. Two measures indicated that the intensity of
competition increased at higher densities of adults, which likely made small fish more
susceptible to predation, thereby causing density-dependent mortality. Long-term
observations indicated that basslet populations were regulated at temporal scales
exceeding two generations. At Lizard Island on the Great Barrier Reef, I also
examined how patterns of recruitment of coral-reef fishes were modified across a range
of natural recruit densities in the presence and absence of resident predators. Predators
decreased recruitment and increased mortality for all species, but these effects varied
considerably among species. The results of each of these studies stress the importance
of both competitive and predatory mechanisms in modifying patterns of abundance
established at the time of larval settlement, as well as regulating local population size. / Graduation date: 2002
