To investigate the changes in temperatures in Okayama area compared with different levels of three urbanization areas such as Tsuyama, Tokyo areas and Hachijo island in Japan. Data of temperatures in Okayama (1891-2009), Tsuyama (1943-2009), Tokyo areas (1876-2009) and Hachijo Island (1907-2009) in Japan was obtained from Japan Meteorological Agency. Changes in temperatures in 4 areas in Japan ...

Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...

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 ...

heavy metal pollution in aquatic ecosystems has become one of the global issues. mollusks such as clams can be used as bioindicators and biomonitors of heavy metal pollution in these ecosystems. in fact, mussels and oysters have been widely used for this purpose. in this study, the concentrations of cadmium were measured in soft tissues of rock oysters )saccostrea cucullata( collected from two ...

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...
