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...

Australia has benefited immensely from the maritime zone provisions of 1982 United Nations Convention on Law Sea (LOSC), particularly for Extended Continental Shelf under Article 76. Australia’s comprehensive submission continental shelf data to Commission Limits in 2004 included occurring inside Antarctic Treaty Area three separate Australian territories; Territory, Heard Island and McDonald I...

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...

This paper considers the contribution engineers can make toward the management of risk in entirely new fields of endeavour. With a few notable exceptions, the application of systematic engineering approaches is generally overlooked in the wider use of risk assessment in non-engineering disciplines. The author has extended the practice of risk management to environmental and ecological systems o...

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 ...

Marine protected areas have long been proposed as a key tool to restore lost food web interactions and increase the resilience of ecosystems climate change impacts. However, changing can result in arrival new species or differentially affect native species, which alter ecosystem dynamics make it difficult predict how will respond protection. The long-spined sea urchin Centrostephanus rodgersii ...
