abstract introduction: dyes are among the most hazardous chemicals in industrial wastesdue to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. the current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. materials & methods: in this experim...

Coral-rich strata of the Leitha Limestone of Badenian age (Middle Miocene) at the type-locality in Grosshoeflein (Burgenland province, Austria) were re-interpreted from an actualistic viewpoint in comparison with Recent Bahamian and Arabian Gulf coral communities. The investigated outcrop (quarry "Fenk'j is interpreted as a sequence of framebuilding coral carpets and non-framebuilding biostroma...

the qom formation in southwest kashan in sanandaj-sirjan fore arc basin has a thickness of 190 meters and is composed of medium to thick and massive bedded limestone, marly limestone, sandy limestone, marl and coglomerates. study of these deposits led to recognition of nine microfacies related to a carbonate platform. the high presence of perforate foraminifera in most of the recognized microfa...

Home Island is one of the two main inhabited islands of the Cocos (Keeling) Islands, situated about 2800 km north-west of Perth. The island has an average elevation of approximately 2 m above MSL and supports a population of about 450. The geology of the island consists of coral sediments overlying a volcanic seamount. The upper sediments are of primary importance from a hydrogeological viewpoi...

Coral reefs are consistently and increasingly subject to acute disturbance events that often lead to a reduction in live coral cover with concomitant effects on the diversity and abundance of coral reef fishes. Here we examine changes in both hard coral and reef-fish assemblages over 15 yr following major losses of coral from exposed reefs in 2 widely separated sectors of the Great Barrier Reef...

I n the simplest sense, coral reefs are wave-resistant piles of limestone and calcareous sediments built by a thin veneer of living organisms (Hubbard 1997). But these piles are of great ecological and resource significance for their massiveness, extremely high biodiversity, and distinct trophic structure and primary production. Reefs grow most prolifically in clear, warm, shallow, and nutrient...

The article deals with the lithofacial features of Asselian and Sakmarian limestone Cisuralian Series Permian System, composing particular mountains Yuraktau, Kushtau Tratau on right bank Belaya River near city Sterlitamak in Bashkir PreUrals. Biohermic bioclastic (detrital) lithofacies are distinguished composition. types represented by bryozoans coral framestones rudstones, tubiphytes packsto...

The Persian Gulf is northern part of the ROPME Sea Area (RSA), and is semi-enclosed shallow sea which located in subtropical climate. Measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. This research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the Persian...
