In this study, the amount of nickel and vanadium elements in the soft tissues of rock oysters (Saccostrea cuculata) and sea water from coastal areas of Qeshm Island, the biggest island of Persian Gulf located in the south of Iran, were measured to evaluate the contamination of the aquatic environment and organisms. Following the bioassay, weighing and chemical digestion of the samples, finally...

We demonstrate two distinctive effects of strain-induced island-island interaction on island size and spatial distribution during coarsening of 2D islands. When coarsening proceeds via only mass transport between islands, the interaction broadens the island size distribution, leading to a power-law dependence of island size uniformity on island number density. When coarsening proceeds via islan...

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...

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 ...

Many insular vertebrates have undergone rapid and dramatic changes in body size compared to their mainland counterparts. Here we explore the relationship between two well known patterns of island body size the tendency for large-bodied species to dwarf and small-bodied species to get larger on islands, known as the ‘‘island rule’’, and the scaling of maximum and minimum body size of island asse...

A theoretical model for the Volmer-Weber growth of three-dimensional metal islands is proposed, with a dipolar island edge-edge interaction. The existence of such an island edge effect makes the island shape dependent on island size. Furthermore, it induces a stable island size against coarsening, leading to self-assembled islands of uniform size. The dependence of the stable island size on tot...

background: marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. methods: in this study, concentrations of heavy metals were measured in saccostrea cucullata collected from seven sites on ...
