Outbreak of Skeletonema costatum Bloom and Its Relations to Environmental Factors in Jiaozhou Bay, China
The marine diatom Skeletonema costatum is commonly found in coastal and estuarine areas from the temperate zones to the tropical zones. Blooms caused by Skeletonema costatum have been reported in almost all the eastern coastal regions of China seas. Jiaozhou Bay, located at the middle of Yellow Sea of China, is a shallow semi-closed basin. Skeletonema costatum constitutes a major fraction of do...
متن کاملDiversity of cultivable protease-producing bacteria in sediments of Jiaozhou Bay, China
Although protease-producing bacteria are key players in the degradation of organic nitrogen and essential for the nitrogen recycling in marine sediments, diversity of both these bacteria and their extracellular proteases is still largely unknown. This study investigated the diversity of the cultivable protease-producing bacteria and their extracellular proteases in the sediments of the eutrophi...
متن کاملEnvironmental factors shape sediment anammox bacterial communities in hypernutrified Jiaozhou Bay, China.
Bacterial anaerobic ammonium oxidation (anammox) is an important process in the marine nitrogen cycle. Because ongoing eutrophication of coastal bays contributes significantly to the formation of low-oxygen zones, monitoring of the anammox bacterial community offers a unique opportunity for assessment of anthropogenic perturbations in these environments. The current study used targeting of 16S ...
متن کاملDistribution and Speciation of Dissolved Iron in Jiaozhou Bay (Yellow Sea, China)
The distribution of total dissolved iron (DFe) and its chemical speciation were studied in vertical profiles of the shallow and semi-closed Jiaozhou Bay (JZB, China) during two contrasting periods: summer (July 19th, 2011) and spring (May 10th, 2012). Samples collected from the surface, middle and bottom layers were analyzed by competitive ligand exchange-adsorptive cathodic stripping voltammet...
متن کاملContribution of Shellfish Consumption to Lower Mercury Health Risk for Residents in Northern Jiaozhou Bay, China
Fish and marine mammal consumption are an important pathway for human exposure to mercury. The low mercury content in shellfish poses a low mercury health risk to people who consume shellfish. The objectives of this study are to detect mercury concentrations in different species of shellfish and to calculate the mercury health risk from shellfish consumption among traditional residents near nor...
