Abstract:

The marine environment presents fewer absolute geographic barriers to gene flow than its terrestrial and freshwater counterparts. In addition, the prevalence of planktonic larval stages in marine taxa provides potential for gene flow across large geographic distances. These observations raise two fundamental questions. How do new species arise in the marine environment? Considering the potential for gene flow in marine systems, it remains unclear to what extent allopatric speciation alone can account for the high levels of diversity observed in the marine realm, whether marine speciation also

Abstract:

The first detailed investigation of Maldivian rim island development and reef-to-island connectivity is presented. Study sites were selected on windward and leeward rim aspects of Huvadhu Atoll, and analyses were undertaken at a millennial, contemporary and near-future temporal scales. At millennial temporal scales, contrasting models of island development were presented for the windward and leeward sites. Marked between-site differences were found in the timings of island initiation (2,800-2,000 cal. yr. B.P. and 4,200-3,600 cal. yr. B.P. at the windward and leeward sites respectively). Hence

Abstract:

Sponges contribute to large number of functions in coral reef ecosystems. Among these, bioerosion is perhaps one of the most widely studied, largely due to the important contribution of excavating sponges to the carbonate budget on coral reefs (up to 95 % of the total internal bioerosion). Despite our current knowledge, much of the literature is centred on individual-based observations, and little is known about their ecological role and interactions with other reef taxa in complex coral reef systems. The aim of this thesis was to quantify the ecological interactions of bioeroding sponges with

Abstract:

Coral reefs are one of the most diverse and complex ecosystems on the planet and provide incomes, food, and important ecosystem services for hundreds of millions of people. However, reefs are in global decline and are changing from highly diverse and topographically complex ecosystems dominated by coral species to species-poor and structurally simple ecosystems dominated by macroalgae. The reason of this decline is complex but can be attributed to multiple local stressors such as overfishing, marine pollution and declining water quality, and global stressors such as global warming and ocean ac

These areas were revisited in 2005 and data were collected by the same methods and at the same depths as in 1988. Data from 1988 and 2005 were compared to determine if the coral reefs had undergone significant changes, and what specific changes had occurred. Chi-square analysis determined that community composition data collected in 1988 are significantly different from data collected in 2005 at all sites and depths within the categories of cor

Coral reefs are in global decline, with seaweeds increasing as corals decrease. Though seaweeds have been shown to inhibit coral growth, recruitment, and survivorship, the mechanism of these interactions is poorly known. Here we use field experiments to show that contact with four common seaweeds induces bleaching on natural colonies of Porites rus. Controls in contact with inert, plastic mimics of seaweeds did not bleach, suggesting treatment effects resulted from allelopathy rather than shading, abrasion, or physical contact.

Abstract:

Corals, the foundation species of tropical reefs, are in rapid global decline as a result of anthropogenic disturbance. On many reefs, losses of coral have coincided with the over-harvesting of reef herbivores, resulting in ecosystem phase-shifts from coral to macroalgal dominance. It is hypothesized that abundant macroalgae inhibit coral recovery and recruitment, thereby generating ecological feedback processes that reinforce phase-shifts to macroalgae and further diminish reef function. Notwithstanding, the extent to which macroalgae directly outcompete coral, the mechanisms involved, and th

Further, understanding where the influence of particular management interventions rank relative to other potential drivers of community structure is important in understanding potential and realised management success.

Abstract:

Herbivory is a key process that mediates the abundance of primary producers and community composition in both terrestrial and aquatic ecosystems. On tropical coral reefs, changes in herbivory are often related to phase shifts between coral-dominance and dominance by seaweeds, or foliose macroalgae. Resilience or capacity to resist and reverse such phase shifts is, therefore, viewed as a critical function on coral reefs.

Over the last decade there has been a vigorous debate among ecologists about the relative importance of pre- and post-settlement processes on the dynamics of benthic populations of coral reef fish.

This variability is thought to occur as a result of the mortality and dispersal of pelagic larvae. In contrast, those advocating the importance of post-settlement processes claim that competition (f

The demise of reef-building corals potentially lies on the horizon, given ongoing climate change amid other anthropogenic environmental stressors. If corals cannot acclimatize or adapt to changing conditions, dramatic declines in the extent and health of the living reefs are expected within the next half century. The primary and proximal global threat to corals is climate change. Reef-building corals are dependent upon a nutritional symbiosis with photosynthetic dinoflagellates belonging to the group Symbiodinium.
