Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...

A total of 154 samples of marine (n=51) and freshwater fish (n=103) were obtained from fish markets in Elazig Province of eastern Turkey. These samples were tested for Campylobacter, Listeria and Salmonella using culturing and biochemical methods. Campylobacter failed to be detected in any freshwater or marine fish samples. Listeria was detected in 22 and 14 of gill and skin samples from freshw...

statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

background and objectives: phytoplanktons are organisms with a very high diversities and global distribution in different habitats. the high distribution of phytoplankton is due to ecological flexibility and their ability to tolerate different climatic conditions and environmental stress. phytoplankton is the most sensitive biological indicators of water resources. the purpose of this study was...

feeding habits of caspian marine shad alosa braschnikowii (borodin, 1904), inhabiting in the western part of caspian sea such as prey spectrum and seasonal dynamics have been studied. as in other parts of caspian sea, throughout the year, the main hunt of caspian marine shad constituted kilkas, gobies and shrimps while other groups of zoobenthos were represented in a lesser extent. importance o...

conclusions calcined coral/sodium nitrate as a new, efficient, and natural heterogeneous catalyst used in aldol condensation reaction of ketones and aldehydes led to β-hydroxyketones in good to high yields in appropriate condition. materials and methods marine coral (acropora sp.) was washed several times using methanol-ethyl acetate and deionized water and then dried in an oven at 80°c for 48 ...

To achieve an ‘ecosystems approach’ for marine resource management, we need to disentangle human impacts from natural variability, over a range of temporal and spatial scales. This Theme combines physical modelling and trophic dynamics to re-assess past changes in marine ecosystems and predict their future development. It includes consideration of the ecological impacts of renewable energy sche...
