The Black, Azov, Caspian and Aral Seas, remnants of the intracontinental Paratethys basin, are home to a spectacular diversity of crustaceans. This study examines the past history of the Ponto-Caspian fauna through comparative phylogeographical studies on both benthic and planktonic taxa, based on an examination of nucleotide diversity in the mitochondrial, cytochrome c oxidase subunit 1 (COI) ...
The prediction of ocean waves is a highly challenging task in coastal and water engineering general due to their very high randomness. In the present case study, an analysis wind, sea flow features, wave height southern coasts Caspian Sea, especially off-coast waters Mazandaran Province Northern Iran, was performed. Satellite altimetry-based significant heights associated with period observatio...
Eryngium caucasicum Trautv and Froriepia subpinnata were found in natively in the eastern parts of the south Caspian Sea coasts. Antioxidant activity of E. caucasicum Trautv and F. subpinnata were investigated employing six in vitro assay systems. IC50 for DPPH radical-scavenging activity was 0.27 ± 0.02 for E. caucasicum leaves and 0.42 ± 0.03 mg ml for F. subpinnata, respectively. The extract...
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...
breeding biology of the great cormorants phalacrocorax carbo sinensis is assessed in thesouthern coasts of the caspian sea, iran during the years 2008-2010. about 84 nests located on 63 trees wereexamined. nests were built on large trees located in abbas abad marsh, gilan province. initially, eggs werefound on first week of april and egg laying continued until the last week of may. clutch size ...
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 ...
