Molecular diversity of Symbiodinium spp. within six coral species in Larak Island, the Persian Gulf
Authors
Abstract:
Reef-building coral harbor communities of photosynthetic taxa of the genus Symbiodinium (zooxanthellae). The genus Symbiodinium is currently classified into nine genetic clades (A–I). Various corals harbor different Symbiodinium clades; some show specificity to a single strain. Coral and their zooxanthellae are sensitive to environmental stresses. In the Persian Gulf, coral reefs are subject to harsh environmental conditions including extreme temperatures and high salinity. This is the first study to use clade specific primers to clarify the diversity of Symbiodinium in each coral species of Larak Island. For this purpose six coral species were collected at two different locations in Larak Island. After DNA extraction, PCR amplification was performed using clade specific primers. The results showed that multiple Symbiodinium clades are hosted by most coral species. In addition, among thirteen obtained Symbiodinium sequences, the frequency of either tree clades, A, C and D was almost the same. Corals species may contain different clades of Symbiodinium depending on the region and on the tolerance characteristics of each clade. Thus, knowledge of zooxanthellae diversity associated with scleractinian can contribute to a better understanding of the sensitivity of corals to environmental conditions.

full textIdentification of Ascidians (Tunicata: Ascidiacea) around Larak Island in the Persian Gulf
Despite the variety of marine organisms recorded from the Persian Gulf, acidians located along the Persian Gulf have not received much attention. We collected Ascidian samples from four sites along Larak Island (Persian Gulf) using Scuba diving and snorkeling at a depth that ranged from 5-15 m. Taxonomic identification was carried out by authoritative keys and texts. We found 4 species that be...

Standing biomass of coral fish was estimated by the Underwater Visual Census method(UVCm) and belt transect in five stations (St.) (dead corals, continuous and developed reefs, discrete and undeveloped reefs, Acropora spp. in small amounts and rocky reefs), in Larak Island from Sep.2020 to Apr.2021seasonally.The maximum and minimum of standing biomass was estimated 908.79 (Kg/Km2) and 235.85 ...

Thermal anomaly is among factors initiating coral bleaching and mortalities and threatening coral reefs worldwide. Therefore, susceptibility of corals to thermal stress is a central concern in reef conservation. In this study, we evaluated underwater temperature during 2012-13 and bleaching status of corals during summer 2012 in Hengam Island located in the eastern Persian Gulf. Hengam coral...
full textGenetic Identification of Symbiodinium in Genus Acropora off Farur Island, Persian Gulf
Coral reefs which form some of the most diverse ecosystems on Earth support many symbiotic relationships. Symbiodinium can provide up to 90% of a coral.s energy requirements. Temperature rise, turbid water and high salinity in the Persian Gulf were among the factors separating zooxanthellae from corals and result in bleaching phenomenon. Therefore, it is crucial to identify Symbiodinium of the ...

Shell selection indices of the dominant hermit crab Clibanarius signatus Heller, 1861, in the Larak Island were studied from September 2011 to June 2012. Among 739 sampled specimens, 41 different gastropod shell types were selected as shelters based on their abundance and local availability. A significant positive correlation (P<0/01) was found between the dimensions of the hermit crab, Cli...
