Background and Objective: Mercury (Hg) contamination in marine ecosystems is a major threat to human health in the developing countries like Iran. The main route of mercury exposure is from consumption of fish and seafood. Upon entering mercury in human bodies, Hg is converted into methyl mercury, which may lead to serious implications including neurological disorders, reproductive abnormalitie...
BACKGROUND Knowledge about Alburnoides remains lacking relative to many other species, resulting in a lack of a systematic position and taxonomic diagnosis. Basic biological information for Alburnoides has been constructed, and it is necessary to understand further and obtain more information about this species. Its phylogenetic relationships are still debated and no molecular data have been us...
Modern satellite gravity missions and ground gravimetry provide operational data models that can be used in various studies geology, tectonics, climatology, etc. In the present study, sedimentary basins southern part of East European Platform adjoining areas including Caucasus are studied by employing approach based on decompensative anomalies. The new model sediments, implying their thickness ...
caspian sea is the largest enclosed body of water on the earth. since the collapse of soviet union in 1991 and discovering large oil and gas fields, some issues such as political, economic and environmental events, made the caspian sea important. the ecology of the sea are being endangered due to several issues such as petroleum extraction, river and sea pollutions, water level rise, biological...

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...
Proof of species existence in different regions can be useful for studying the migration pattern of the species. The use of non-invasive methods such as eDNA can be very effective in tracking and dispersing and improving the management of water resources and species. In this study, 15 water samples were taken from different areas of the southern Caspian Sea basin. Amino-modified silica-coate...
