“…Many studies have shown the effects of disturbances on size-frequency distributions, whereby large massive colonies, if impacted, will take decades to recover to similar sizefrequency distributions (Endean 1973;Done 1987;Endean et al 1989). The recovery on some of Palau's reefs was similar to, albeit less rapid than, recovery on a lava flow reported by Tomascik et al (1996). Tomascik et al (1996) showed remarkable coral community development on a bare andesitic lava substrate following a major volcanic eruption in the Banda Sea, Indonesia.…”

Tomascik et al (1996) showed remarkable coral community development on a bare andesitic lava substrate following a major volcanic eruption in the Banda Sea, Indonesia. In 5 years, coral coverage averaged over 60%, supporting 124 coral species, which was dominated by Acropora plates (note, the Banda Islands lava site closely resembled this study's Site 1P, Fig.…”

“…For example, wave energy regulates community structure on the west coast of Hawaii, by selecting against less wave-tolerant coral species (Dollar 1982); but more subtly, the energy regime is inversely related to intra-specific genetic diversity, a consequence of differential breakage and clone propagation (Hunter 1993). The dynamics and recovery processes of coral communities are complex because reefs are subjected to a variety of disturbances that vary in intensity, frequency and duration (Pearson 1981;Huston 1985;Done 1987;Hughes 1989;Karlson and Hurd 1993;Tomascik et al 1996). Recovery from major disturbances ranges anywhere from five to hundreds of years, depending on the type of disturbance, the initial conditions and the type of coral community that was impacted (Pearson 1981;Colgan 1987;Endean et al 1989;Done et al 1991;Dollar and Tribble 1993).…”

For example, the recovery of a sheltered stand of 2 m Porites lutea and Diploastrea helipora coral colonies, through recruitment and regrowth, may take hundreds of years to reach former size-frequency structure (Done 1987), while the recovery of shallow Acropora hyacinthus and A. digitifera populations may reach similar size frequency distributions within 5 years after a disturbance (Tomascik et al 1996).…”

Palau’s coral reefs show differential habitat recovery following the 1998-bleaching event

Documenting successional dynamics of coral communities following large-scale bleaching events is necessary to predict coral population responses to global climate change. In 1998, high sea surface temperatures and low cloud cover in the western Pacific Ocean caused high coral mortality on the outer exposed reefs of Palau (Micronesia), while coral mortality in sheltered bays was low. Recovery was examined from 2001 to 2005 at 13 sites stratified by habitat (outer reefs, patch reefs and bays) and depth (3 and 10 m). Two hypotheses were tested: (1) rates of change of coral cover vary in accordance with habitat, and (2) recovery rates depend on recruitment. Coral cover increased most in the sheltered bays, despite a low recruitment rate, suggesting that recovery in bays was primarily a consequence of remnant regrowth. Recruitment densities were consistently high on the wave-exposed reefs, particularly the western slopes, where recovery was attributed to both recruitment and regrowth of remnants. Recovery was initially more rapid at 10 m than 3 m on outer reefs, but in 2004, recovery rates were similar at both depths. Rapid recovery was possible because Palau's coral reefs were buffered by remnant survival and recruitment from the less impacted habitats.

“…By far the greatest contribution at all depths was made by the same fastgrowing branching and plating corals that were dominant before the predation event. In Indonesia, the same suite of corals colonized a denuded area at a rate exceeding 12% per year (Tomascik et al 1996). The rapid linear extension rate of individual corals came, however, at the expense of a marked reduction in skeletal density.…”

ABSTRACT. We review the evidence for multiple ecological states and the factors that create ecological resilience in coral reef ecosystems. There are natural differences among benthic communities along gradients of water temperature, light, nutrients, and organic matter associated with upwelling-downwelling and onshoreoffshore systems. Along gradients from oligotrophy to eutrophy, plant-animal symbioses tend to decrease, and the abundance of algae and heterotrophic suspension feeders and the ratio of organic to inorganic carbon production tend to increase. Human influences such as fishing, increased organic matter and nutrients, sediments, warm water, and transportation of xenobiotics and diseases are common causes of a large number of recently reported ecological shifts. It is often the interaction of persistent and multiple synergistic disturbances that causes permanent ecological transitions, rather than the succession of individual short-term disturbances. For example, fishing can remove top-level predators, resulting in the ecological release of prey such as sea urchins and coraleating invertebrates. When sea urchins are not common because of unsuitable habitat, recruitment limitations, and diseases, and when overfishing removes herbivorous fish, frondose brown algae can dominate. Terrigenous sediments carried onto reefs as a result of increased soil erosion largely promote the dominance of turf or articulated green algae. Elevated nutrients and organic matter can increase internal eroders of reef substratum and a mixture of filamentous algae. Local conservation actions that attempt to reduce fishing and terrestrial influences promote the high production of inorganic carbon that is necessary for reef growth. However, global climate change threatens to undermine such actions because of increased bleaching and mortality caused by warm-water anomalies, weakened coral skeletons caused by reduced aragonite availability in reef waters, and increased incidence of diseases in coral reef species. Consequently, many coral reefs, including those that are heavily managed, have experienced net losses in accumulated inorganic carbon in recent decades and appear likely to continue this trend in coming decades. Reefs urgently need to be managed with a view to strengthening their resilience to the increased frequency and intensity of these pressures. Ecological targets must include the restoration or maintenance of species diversity, keystone species, spatial heterogeneity, refugia, and connectivity. Achieving these goals will require unprecedented cooperative synergy between human organizations at all political levels, from intergovernmental to local.
