Records of the species are from a fieldwork at Mayotte in November 2009, complemented by a literature review. 58 species are listed including 24 new records for Mayotte region. The inventory includes 42 crabs, 11 shrimps and 5 coenobitids ( Birgus latro , Coenobita spp.). Crabs Grapsoidea ( Cardisoma , Geograpsus , Grapsus , Metasesarma , Metopograpsus , Neosarmatium , Pachygrapsus , Parasesarma , Perisesarma , Pseudograpsus , Pseudohelice , Ptychognathus , Sesarmops , Thalassograpsus , and Varuna ) are best represented together with the Ocypodoidea ( Chaenostoma , Dotilla , Macrophthalmus , Ocypode , and Uca ). Shrimps belong to the genera Atyoida , Caridina , Macrobrachium , and Palaemon . Biotopes investigated include rivers, mangroves, estuaries, land, and coastal areas with a special attention paid to Malamani mangrove in the west coast of Mayotte Island. The fauna of Mayotte region is predominantly indo-west pacific in its composition (45 species). Thirteen species are distributed only in the western Indian Ocean, but only one is perhaps endemic to the region. A comparison with the fauna of the Seychelles Islands shows that at least 6 additional species, widely distributed in the Indo-West Pacific, are potentially also present in Mayotte region.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"592 1","pages":"1-60"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70939420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anomuran fauna of Mayotte region is predominantly Indo-West Pacific in its composition (85 % of the species). Twelve species are distributed in Western Indian Ocean only. A comparison with the anomuran fauna of adjacent regions shows that at least 129 anomuran species are potentially present in Mayotte region.

At each of four sites around the island, point intercept methodology over two 50 m transects yielded an average benthic cover of 26% live hard coral. The maximum live hard coral cover observed was 47% on the northern side of the island where fishing boats anchor overnight to seek shelter from the southwest monsoon. The minimum of 3% live hard coral was observed on the west side, which is the inhabited area of the island and where there is the greatest amount of anthropogenic activity. A total of 38 hard coral genera and 115 fish species were recorded across all transects. The average biomass of fish per transect was 2135.5 kg/ha and the populations were mostly comprised of herbivores which correlated with the abundance of dead coral, algae overgrowth, and lack of predator fish. Crown-of-thorns starfish ( Acanthaster planci ) were present at all sites with a maximum of 15 individuals sighted on both the North Shallow and South Shallow transects. In general, damage from anchors and destructive fishing practices have gravely impacted Pulau Durai‟s reefs in the past. Present threats include continued anchoring, over-fishing and a current infestation of crown-of-thorns starfish, which are negatively affecting the remaining health and abundance of living coral. Pulau Durai and its neighbouring island, Pulau Pahat, were declared a marine protected area in July 2011. Given the depleted state of this reef, it will be imperative to establish a “no-take” fishing area to restore the fish populations, ban anchoring on the reef to stop the destruction of coral, and if possible, remove the crown-of-thorns starfish.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"591 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2013-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70939414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the Philippines, this protected species is rarely seen in habitats close to human settlement. However, in a protected area like the Tubbataha Reefs Natural Park (TRNP), C. cornuta are commonly encountered at the vicinity of the Ranger Station. With a dearth of information about this giant reef gastropod, notes on marked-recaptured C. cornuta in TRNP were taken from December 2009 until January 2011; and its trade was noted through surveys of some souvenir shops in Puerto Princesa City. Most of the sampled C. cornuta were large, suggesting the absence of exploitation at the study site. Regression analyses suggest that the shell’s dimensions are significant determinants of body weight. Growth rates declined as shell size increased. Although exploitation of C. cornuta is prohibited under the Philippine law, their shells were openly displayed for sale in a number of souvenir shops in Puerto Princesa City. Given the limited area covered in this study, a nationwide survey is needed to fully document its status in the wild and the extent of its trade. Information on population, growth, survival, other aspects of its biology and its exploitation are needed in proposing a more relevant conservation measure for this vanishing giant reef gastropod.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"595 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70939485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of the survey was to i) compile for the first time for this atoll a scleractinian coral check-list, ii) estimate the atoll total richness, iii) estimate intra-atoll richness variation and iv) describe preliminary patterns of community structure according to geomorphology and location criteria. The survey was stratified by the main reef geomorphological units. A total of 173 species of scleractinia belonging to 49 genera were recorded, including several species new to Maldives. Conversely, a number of species of genera quite common in the Indian Ocean were absent of the list of Pocilloporidae. Average richness per station was nearly 60 species. Richness ratio between slopes and flats/tops were between 3 and 1.3, with an average of 2.1, highlighting richer slopes than flats and tops. Differences of community composition between geomorphologic strata and between oceanic/lagoonal reefs were significant. Central lagoonal reefs provided highest richness, and highest coral cover as well. These findings are critical to plan for the conservation of Baa Atoll biodiversity.","PeriodicalId":34898,"journal":{"name":"Atoll Research Bulletin","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70919613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
