In paper based on the results of previous studies and latest investigations of mud volcanoes in the South Caspian basin the depth occurrence of fluid, mud and rocks are calculated and modeled. Major factors causing formation of diapirism/mud volcanism in the South Caspian basin are Pliocene-Quaternary high sedimentation rates (up to 3 km/my), super thick sedimentary cover (up to 25 30 km), pred...

the genus alburnoides jeitteles, 1861 in iran is reviewed, and diagnoses are presented for all eight recognized species. alburnoides eichwaldii, a. holciki, a. idignensis, a. namaki, a. nicolausi, a. petrubanarescui, a. qanati and a. tabarestanensis are considered valid and three new species are described: alburnoides coadi sp. n., from namrud river in kavir basin, a. parhami sp. n., from atrak...

Considerable uncertainty exists in determination of the phylogeny among extant members of the Dreissenidae, especially those inhabiting the Ponto-Caspian basin, as multiple systematic revisions based on morphological characteristics have failed to resolve relationships within this group of bivalves. In this study we use DNA sequence analyses of two mitochondrial gene fragments, 16S rRNA and cyt...

Remote measurements of different environmental parameters received during last 30 years are used for the synthesis of a Complex Simulation Model (CSM) describing the combined water regimes of the Aral-Caspian System (ACS) including the consideration of aquatic and climatic natural processes. The problem of stabilizing the sea levels of these two water bodies is modelled and a solution obtained ...

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...

Nowadays, a noticeable part of the relations among the states turn around the environment protection. Therefore, the right for ever-creasing use of the existing resources of this inland sea cannot be exclusive to any Caspian State and the aftermath involves all countries of this basin. In this respect, agreement on political border and boundaries with the Caspian Sea?s ecosystem is a difficul...

The genus Alburnoides Jeitteles, 1861 in Iran is reviewed, and diagnoses are presented for all eight recognized species. Alburnoides eichwaldii, A. holciki, A. idignensis, A. namaki, A. nicolausi, A. petrubanarescui, A. qanati and A. tabarestanensis are considered valid and three new species are described: Alburnoides coadi sp. n., from Namrud River in Kavir basin, A. parhami sp. n., from Atrak...

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...
