“…The reefs surveyed in Micronesia all harbored generally high abundances of coral. Kosrae reefs hosted the highest abundances (up to 77% coverage) of coral, consistent with previous observations (Richards 2015). More generally across the islands and atolls, coral and macroalgal coverages were in line with previous observations on other Micronesian reefs including Pohnpei, Chuuk, andYap Islands (Abraham et al 2004, Goldberg et al 2008).…”

Microorganisms are central to the functioning of coral reef ecosystems, but their dynamics are unstudied on most reefs. We examined the microbial ecology of shallow reefs within the Federated States of Micronesia. We surveyed 20 reefs surrounding 7 islands and atolls (Yap, Woleai, Olimarao, Kosrae, Kapingamarangi, Nukuoro, and Pohnpei), spanning 875053 km2. On the reefs, we found consistently higher coral coverage (mean ± SD = 36.9 ± 22.2%; max 77%) compared to macroalgae coverage (15.2 ± 15.5%; max 58%), and low abundances of fish. Reef waters had low inorganic nutrient concentrations and were dominated by Synechococcus, Prochlorococcus, and SAR11 bacteria. The richness of bacterial and archaeal communities was significantly related to interactions between island/atoll and depth. High coral coverage on reefs was linked to higher relative abundances of Flavobacteriaceae, Leisingera, Owenweeksia, Vibrio, and the OM27 clade, as well as other heterotrophic bacterial groups, consistent with communities residing in waters near corals and within coral mucus. Microbial community structure at reef depth was significantly correlated with geographic distance, suggesting that island biogeography influences reef microbial communities. Reefs at Kosrae Island, which hosted the highest coral abundance and diversity, were unique compared to other locations; seawater from Kosrae reefs had the lowest organic carbon (59.8-67.9 µM), highest organic nitrogen (4.5-5.3 µM), and harbored consistent microbial communities (>85% similar), which were dominated by heterotrophic cells. This study suggests that the reef-water microbial ecology on Micronesian reefs is influenced by the density and diversity of corals as well as other biogeographical features.

“…Survey of corals diversity on Gaspar Strait, Bangka Island, and the western part of Bangka Island by various methods, i.e., line transect, belt transect, roving, were recorded 98, 89, 71 corals species, respectively (Siringoringo et al, 2006;Hadi, 2013, 2015). Other numerous surveys with more applied methods also found more species (Richards and Rosser, 2012;Waheed and Hoeksema, 2014;Richards, 2015). A similar study on Scleractinian corals with the addition of museum collections examination also recorded more corals species (Richards et al, 2014).…”

Bangka Belitung Islands (Sumatra, Indonesia) has various coastal resources, e.g., coral reefs, seagrass beds, mangrove forests. However, the coral community has been threatened by anthropogenic activities, i.e., tin mining and illegal tin mining. Threatened species assessment is important for mitigation of coral losses and management. The ojective of the present study was to examine the status of Scleractinian corals in Bangka Belitung Islands, Indonesia. A line intercept transect was performed for the coral reef survey. Live and dead coral cover were recorded in the three locations. Corals species were identified following taxonomic revisions. The results showed that there were 142 species of Scleractinian corals recorded from Bangka Belitung Islands. Of these, 22 species are the new report from the areas of the the eastern part of Belitung Island. Family of Merulinidae, Acroporidae, and Poritidae were predominant group in this region. It is concluded that the condition of the coral reef ecosystem in the Belitung Islands is relatively good, but fair in Gaspar Strait and Bangka Island.

In an era of rapid global change, conservation managers urgently need improved tools to track and counter declining ecosystem conditions. This need is particularly acute in the marine realm, where threats are out of sight, inadequately mapped, cumulative, and often poorly understood, thereby generating impacts that are inefficiently managed. Recent advances in macroecology, statistical analysis, and the compilation of global data will play a central role in improving conservation outcomes, provided that global, regional, and local data streams can be integrated to produce locally relevant and interpretable outputs. Progress will be assisted by (a) expanded rollout of systematic surveys that quantify species patterns, including some carried out with help from citizen scientists; (b) coordinated experimental research networks that utilize large-scale manipulations to identify mechanisms underlying these patterns; (c) improved understanding of consequences of threats through the application of recently developed statistical techniques to analyze global species' distributional data and associated environmental and socioeconomic factors; (d) development of reliable ecological indicators for accurate and comprehensible tracking of threats; and (e) improved data-handling and communication tools.
