The predatory cladoceran Cercopagis pengoi has extended its range over the past decade from the Ponto-Caspian basin into the Baltic Sea and the Laurentian Great Lakes. This study employs mitochondrial DNA (mtDNA) sequence analysis to elucidate the invasion corridors exploited during this range expansion. The Caspian and Black Sea populations of C. pengoi exhibit marked genetic divergence, enabl...

marine environment of the caspian sea, due to extensive human exploitation and discharge of large magnitudes of urban, industrial and agricultural waste, is under extensive pressure and human wastes threaten marine life and ecosystem of the sea. therefore, there is a substantial need for a good understanding of physical and chemical characteristics of the caspian waters. however, the data avail...

Seasonal variations of the seawater properties (e.g. temperature, salinity, density and chlorophyll-a) in western part of the southern coastal waters of the Caspian Sea near the Iranian coast were studied. A portable CTD probe was applied for profiling from sea surface to bottom at 23 stations. Maximum depth of the profiling stations was more than 470 m in the study area. Vertical structure of ...

This study evaluated the feasibility of a drowning intervention package in northern Islamic Republic of Iran. A quasi-experimental design used pre- and post-observations among residents and tourists in water-recreation beach areas of intervention and control regions by the Caspian Sea and in residents near the Caspian Sea coastline. The fatal drowning rate in the studied resident population in ...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

In this paper the main factors that influence the Caspian Sea level rising and the probable and improbable factors are discussed in detail. A cyclical behavior of the level of the Caspian Sea according to local records was proposed. This cyclic fluctuation of the sea level is the long-term behavior of the sea so that the investigation is not restricted to a specific time interval. The statistic...

Caspian Sea is the largest land locked water body in the world and has been characterized by significant relative sea-level changes since the Pliocene. The sea-level oscillations have strongly impacted the coastal areas depending on geomorphological setting. This study aims to investigate the impacts of sea level oscillations on low-lying coasts of the southeastern flank of the Caspian Sea...

the caspian sea region, because of the proximity of two permanent powers - russia and iran- and the emergence of newly independent republics, is one of the most dynamic places in the world. in addition, the continuity of interests of other global actors, including the united states and europe, with the coastal countries has added to the complexity and dynamics. in this regard, the region energy...

  Wild common carp of the Caspian Sea is one of the important fish in the north of Iran, which has been introduced to inland aquaculture. Its genetic characteristics are investigated to set up for breeding programs that are still unknown. Using wild common carp in aquaculture is limited for uncontrolled variation in performance of fish derived from undomesticated breeders. A 7×7 factorial matin...
