common kilka clupeonella cultriventris (nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the caspian sea. a total of 60 specimens of adult common kilka were sampled from two seasons. fifteen pairs of microsatellites previously developed for a.sapidissima, c. pallasi, c.harengus, and s. pilchardus were tested for ...

Although emerging evidence indicates that deep-sea water contains an untapped reservoir of high metabolic and genetic diversity, this realm has not been studied well compared with surface sea water. The study provided the first integrated meta-genomic and -transcriptomic analysis of the microbial communities in deep-sea water of North Pacific Ocean. DNA/RNA amplifications and simultaneous metag...

in the recent years, rapid growth of the world’s population and overutilization of fresh water resources have caused fresh water shortage crisis in the world. in spite of the agricultural activities in the northern beaches of iran and also severe decrease of the ground water level, it still has not taken any effective measures to desalinate caspian sea water in large scale. in this research, de...

The aim of this study was to examine the survival dynamics of several epidemic healthcare (HA) and community-associated (CA) meticillin-resistant Staphylococcus aureus (MRSA) in river, sea and swimming pool waters. Six different phage-types of HA-MRSA (Irish 1, Irish 2, EMRSA 15, EMRSA 16, distinct type and non-typable), as well as a community-associated MRSA (CA-MRSA), were examined in this st...

Fossil foraminiferal shells are utilized in paleoceanography to extract information about environmental conditions of the past ocean. Based on several assumptions, the ratio of C and C preserved in their shells is used to reconstruct, for example, the paleoproductivity or the oceanic pCO . Metabolism of the living organism and the sea water chemistry, 2 however, can influence the incorporation ...

The conversion of saltwater and brackish water into fresh through desalination has gained significant importance as a solution to the worldwide scarcity resources. Reverse Osmosis (RO) method been effectively utilized generate from sources water. This research aims examine variables that affect performance reverse osmosis process. effectiveness membrane was assessed experiments explored impact ...

The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...
