“…The non-structural adjacent reef of Hon Nai Islands is comparable with other reefs of southern Vietnam in morphology, the degree of development of coral structures, qualitative and quantitative composition to corals [9,11,21,22]. From 169 scleractinian species found on this reef, 58% -69% werecommon with reefs of the Nha Trang Bay, Con Dao Island, the Gulf of Siam and Tonkin Bay [12,23].…”

A protected non-structural reef in Сam Ranh Bay in southern Vietnam was surveyed. A high diversity was found among scleractinian and accompanying mass species of macrobenthos. Thirtyfour species were identified only among genera Acropora; it made 80% of the total composition of these Scleractinian on reefs of Vietnam and a quarter of the total abundance of these corals on reefs in the Indo-Pacific. A new species, Favites сamranensis sp. nov, earlier unknown for science, has been found. The vertical bionomic zonality corresponding to zonal distribution of environmental factors on the reef under study is similar to that on reefs of the Siam Bay, different regions of the Pacific and the Caribbean Basin. Expansion of prosperous state of the reef and minimization of anthropogenic influence on some reefs of Vietnam had a positive effect on their state. It is supposed, that the reef at Hon Nai Island is obliged by the prosperity to security measures and minimization of the anthropogenous influence, provided with the decision of government SRV and company "Sanest".

“…There are many ecological factors that affect morphology, such as habitat, substrata, depth (Gilmartin 1960), light intensity (Hillis-Colinvaux 1980), wave action and currents (Wyrtki 1961;Buranapratheprat & Bunpapong 1998;Kaandorp 1999;Morton & Blackmore 2001;Latypov 2003).…”

Diversity of Halimeda (Chlorophyta) from the Thai–Malay Peninsula

et al. 2015

The Thai-Malay Peninsula separates the Andaman Sea from the Gulf of Thailand. This barrier is known to affect species distribution and genetic diversity of marine organisms. Biodiversity studies need a correct species taxonomy to interpret their biogeography; this is especially relevant in marine algae where morphological characters are few or cryptic. We address species distributions of the important macroalgal genus Halimeda. The combination of morphological data and chloroplast tufA gene sequences were used to identify species, and to reveal the variation among Halimeda species around the Thai-Malay Peninsula. The morpho-anatomical and molecular analysis showed eight species of Halimeda in Thai and Malaysian waters: Halimeda borneensis, H. discoidea, H. gigas, H. macroloba, H. micronesica, H. minima, H. opuntia, H. renschii, and two undescribed species. Three species, H. minima, H. renschii and H. micronesica, were reported for the first time from the area. Species variation was much greater in the Andaman Sea than in the Gulf of Thailand. Our results show great variation in species composition and genetic variation between the two sides of the peninsula, which could be due to differences in sea-surface currents and environmental differences between the two sides of this important marine barrier.

“…The non structural fringing reef at Noi Island, in terms of its morphology and degree of development of corallogenic structures, as well as the qualitative and quantitative compositions of its corals, is comparable with other reefs of South Vietnam [4][5][6]10]. Among 169 scleractinian species found on these reefs, 58-69% were also recorded on the reefs of Nha Trang Bay, the Con Dao Islands, the Gulf of Thailand, and the Gulf of Tonkin [7,22].…”

112The Hon Nai Islands are a group of islands located 11 km to the east of the coastline between the cities of Cam Ranh and Nha Trang. The largest Noi Island is somewhat more than 0.8 km long from north to south (12°03′50′′ N, 109°19′85′′ E and 12°02′75′′ N, 109°19′70′′ E). The island is made of large blocked dacite and is surrounded by a sandy platform with depths of 6-15 m along the eastern side and 9-20 m at the western coast. The bedrocks of the island and their blocky debris stretch from southwest to northeast in 5-20 m wide bands. Coral settlements develop mostly on submarine bedrock exposures and, in smaller amounts, on a corallogenic substrate that is composed of blocks no more than 1 m in size. The island is the property of the Sanest Co., which abso lutely prohibits any access to its submarine resources. The coral ecosystem developed at the southwestern part of the island is characterized by surprisingly clear water and extremely high species diversity of reef building corals and associated organisms, thus differ ing significantly from the ecosystems of the adjacent mainland and insular reefs [8,12].The specificity of geomorphology and climatic conditions allows one to divide the reefs of the World Ocean, in particular, the reefs of Vietnam, into two types. The reefs of the first type, also called "structural reefs" [33], demonstrate pronounced zonation (com prising lagoons, reef flats, etc.) and strong corallogenic carbonate structure; they are common in the tropical zone of the World Ocean. In reefs of the second type, including the reef at Noi Island, the morphological zonation is weakly pronounced and carbonate depos its develop small scale coral populations that make almost no changes to the substrate profile; however, their bionomical zonation is comparable with that of the structural reefs. These are so called non structural or encrusting reefs that often occur among reefs of the monsoon type [21,33]. The species diversity of the reef at Noi Island, which is unusual for the present time, motivates the necessity for investigations of the species composition and distribution peculiarities of scleractinians and associated macrobenthos of this reef. MATERIALS AND METHODSThe composition and distribution of scleractinians and common macrobenthic species and community structure in each reef zone at Noi Island were studied using scuba gear (Fig. 1). The studies were performed following generally accepted hydrobiological tech niques, with transects and standard frames [25]. The density of branched, massive, encrusting, and funnel form scleractinian colonies and the degree of substrate coverage by corals were estimated along a 100 m long transect using a 1 m 2 frame divided into 100 equal parts. At the same time we also determined the density of common species of macrophytes and echinoderms, HYDROBIOLOGY Abstract-A nonstructural reef at Hon Nai Island in Cam Ranh Bay (southern Vietnam) was investigated. In comparison with most of the coastal continental and island coral reefs of this region, it is characte...
