The Persian Gulf islands are the nesting regions for the severely endangered hawksbill turtle (Eretmochelys imbricata) species. Therefore, the selection of the nesting habitat of this species in the two islands of Qeshm and Hengam was studied by a five-member working group in the spring of 2013 - 2015. Ultimately, 23 and 17 nests were identified in the south of Qeshm Island and in the south and...

The percentage cover and distribution of scleractinian corals were studied at two Iranian islands in the Persian Gulf. Survey techniques involved the use of 20-m line transects placed at 4-9 m depth interval, parallel to the shore. GIS based maps were employed to show the distribution of hard corals. In Farurgan Island, hard coral cover was concentrated in the west and north-west of the island,...

in this study marine sponges of inter tidal zone from hengam island persian gulf were collected by wading at low tides in eskeleh station at  locations 55˚ 53ʹ 40ʺ e & 26˚ 40ʹ 53ʺ n.for identifying identification of sponge samples, acid digestion method as a method of early detection and microtome section to identify the skeletal structure were used.all the identified sponges were from class de...

the materials of this study were collected from intertidal and shallow subtidal habitats of the hengam island coasts from may 2013 to may 2014. a total of 10 species representing eight genera and four families are reported as follows: sphaeromopsis persikolpos khalaji-pirbalouty and wägele 2009, s. sarii khalaji-pirbalouty and wägele 2009, sphaeroma khalijfarsi khalaji-pirbalouty and wägele 201...

the lipid content and composition of the reef-building coral acropora downingi, the largest coral reef of hengam island, were examined throughout a year. the results showed that the lipid content of a. downingi significantly differs in different seasons (t-test, p< 0.05). depending on the season and spawning times, the lipid content of a. downingi ranged from 16.5 to 37.7 % (dry weight). the to...

In the Persian Gulf, Acropora- dominated coral reefs have been damaged by global and local disturbances. Inversion of coral colonies mostly occur due to anchoring and fishing in many coral reefs, particularly those established nearby human societies, like the coral reef of Hengam Island, in the Persian Gulf. The short term growth rates (weight increment) of inversely and normally transplanted c...

In this study marine sponges of inter tidal zone from Hengam Island Persian Gulf were collected by wading at low tides in Eskeleh station at  locations 55˚ 53ʹ 40ʺ E & 26˚ 40ʹ 53ʺ N.For identifying identification of sponge samples, acid digestion method as a method of early detection and microtome section to identify the skeletal structure were used.All the identified sponges were from class De...

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...
