A partial sequence of the mtDNA ND5 gene region was used for population study in Persian sturgeon (west and east areas of southern Caspian Sea). The result showed that although this approach was informative for phylogenetic study in sturgeon, it was less informative for population study in Persian sturgeon.
the gobies are non-commercial fishes in the iranian waters of the caspian sea for which population dynamics and stock status are poorly known. in this survey, we tried to define species diversity and catch per unit effort (cpue) of gobiidae by using beach seine nets in salmanshahr, the southern caspian sea. from march 2011 to april 2012, 224 specimens representing 4 gobiid species, belonging to...
Thousands of Caspian seals (Phoca caspica) died in the Caspian Sea from April to August 2000. Lesions characteristic of morbillivirus infection were found in tissue specimens from dead seals. Canine distemper virus infection was identified by serologic examination, reverse transcriptase- polymerase chain reaction, and sequencing of selected P gene fragments. These results implicate canine diste...
The Caspian tiger (Panthera tigris virgata) flourished in Central Asian riverine forest systems in a range disjunct from that of other tigers, but was driven to extinction in 1970 prior to a modern molecular evaluation. For over a century naturalists puzzled over the taxonomic validity, placement, and biogeographic origin of this enigmatic animal. Using ancient-DNA (aDNA) methodology, we genera...
Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic relationships between two seasonal immigrant forms (namely fall-run and spring-run) of Caspian trout Salmo trutta caspius. In this regard, 62 fin tissue samples were collected from southern parts of the Caspian Sea basin and examined with 16 oligodecamer primers to asses their genetic diversity as well as probable s...
The Caspian seal (Pusa caspica) has declined by more than 90% since 1900 and is listed as endangered by IUCN. We made the first quantitative assessment of Caspian seal by-catch mortality in fisheries in the north Caspian Sea by conducting semi-structured interviews in fishing communities along the coasts of Russia (Kalmykia, Dagestan), Kazakhstan and Turkmenistan. We recorded a documented minim...

this article deals with a comparative analysis of phonological dissimilarities between two iranian dialects in the southern borders of the caspian sea, e.g. taleshi in gilan and kelardashti in mazandaran. the differences are classified and analyzed with an emphasis on the kelardasht’s rudbarak and talish’s alian dialects in two parts of vowel and consonant diversities.
background: main objective of this study was to investigate the invasive activity of the liver fluke, pseudamphistomom truncatum against the caspian seal ( pusa caspica ) and was exemplified at the gross, light microscopy (lm) and electron microscopy (em) levels. methods: the study was done on a freshly dead caspian seal in the southern coast of caspian sea. the checked caspian seal probably be...
Distribution of sibling species Larus cachinnans (Pallas, 1811) and michahellis (J. F. Naumann 1840) were studied on coast the Black Sea. Originally, breeds seaside cliffs rocky islets Southern part Sea Crimean Peninsula. Having adapted to breeding roofs buildings, this is spread north along seaside: Novorossiysk eastern coast, Constanta western one. Additionally, an isolated population low-lyi...
