ABSTRACT Background : Natural uranium exists in earth crust and seawater. The concentration of uranium might increase by human manipulation or geological changes. The aim of this study was to verify susceptibility of laser flourimetry method to determine the uranium concentration in Caspian Sea and Persian Gulf water. Materials and Methods : Laser flourimetric method was used to determine...
Stylophora pistillata is a widely used coral "lab-rat" species with highly variable morphology and a broad biogeographic range (Red Sea to western central Pacific). Here we show, by analysing Cytochorme Oxidase I sequences, from 241 samples across this range, that this taxon in fact comprises four deeply divergent clades corresponding to the Pacific-Western Australia, Chagos-Madagascar-South Af...
This paper addresses how to assess the performance of refractivity-from-clutter (RFC) techniques in different regions of the world with varying duct strengths and statistics. The performance of evaporation duct estimation is investigated in littoral zones such as the North Sea, Wallops Island, Coast of California, Mediterranean, Persian Gulf, and Coast of Brazil. The effects of the radar freque...
یافته کوتاه علمی : اولین گزارش گربه ماهی خال دار (Thunberg 1792 Arius maculatus) از خلیج فارس، ایران
The species Arius maculates (Thunberg 1792) (Siluriformes, Ariidae) is recorded for the first time from the muddy shores of the inter-tidal zone of Bandar Abbas, Persian Gulf, Iran in February 2011. In this study, the morphological features of Arius maculates are described. This species has previously been recorded from Gulf of Oman to Indonesia, north to Japan (locality type). This finding con...
Coral reefs are in rapid decline on a global scale due to human activities and a changing climate. Shallow water reefs depend on the obligatory symbiosis between the habitat forming coral host and its algal symbiont from the genus Symbiodinium (zooxanthellae). This association is highly sensitive to thermal perturbations and temperatures as little as 1°C above the average summer maxima can caus...
changes in the microbial community in response to catastrophic oil spills in marine and fresh water environments have been well documented. molecular methods provide tools for analyzing the entire bacterial community, covering also those bacteria that have not been cultured in the laboratory. in this study, four different microcosms were set up containing sediments collected from the persian gu...
rocky shores are one of the most important habitats of marine environment in coastal areas. they host marine organisms including seaweeds because of existence of strong and stable substrate for their growths. intertidal rocky shores are a prominent feature on coastal areas of qeshm island located at the northern part of strait of hormuz. in order to study biomass of seaweeds on rocky intertidal...
Background and Theoretical Foundations: Coral reefs are one of the world's most attractive ecosystems. They have been covering large parts of the world in the tropic areas. Coral reefs in the Iranian waters of the Persian Gulf are largely limited to the Islands. Many factors, including natural and anthropogenic activities cause stress to the reef communities affecting reef development. Coral bl...
