Amoora cucullata (Meliaceae), a mangrove plant, has folkloric reputation as a medicinal agent in Bangladesh. In this study, the n-hexane, ethyl acetate and methanolic extracts of the stem bark of this plant were subjected to microbiological investigation and brine shrimp lethality bioassay. In case of antimicrobial screening, the ethyl acetate and methanolic extracts appeared to be potent in te...

The geographic boundaries of many important habitat-building shallow estuarine oyster (Family Ostreidae) species are poorly understood, especially in subtropical and tropical waters. These keystone often have extensive historical extant ranges, part because their ability to adapt diverse environmental conditions the transfer introduction a few worldwide for aquaculture production. In addition, ...

The effect of growing height on mortality of Sydney rock oysters, Saccostrea glomerata, caused by Australian winter mortality Mikrocytos roughleyi was evaluated on a commercial intertidal growing lease on the Georges River, NSW, Australia. The mortality level of 35.1"8.4% at normal growing height, fell to 9.3"0.9% when oysters were cultured 300-mm higher, and increased to 52.4"0.2% at 300-mm lo...

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...

The bivalve family Ostreidae has a worldwide distribution and includes species of high economic importance. Phylogenetics and systematic of oysters based on morphology have proved difficult because of their high phenotypic plasticity. In this study we explore the phylogenetic information of the DNA sequence and secondary structure of the nuclear, fast-evolving, ITS2 rRNA and the mitochondrial 1...
