mitochondria1 dna (mtdna) control region sequences were analyzed to evaluate the population genetic structure of persian sturgeon (acipenser persicus) in caspian sea. a total of 45 specimens were collected from the different locations of the caspian sea. mtdna control region was amplified using pcr. direct sequencing was performed according standard method. the results showed that 12 haplotypes...

in the present study, mitochondrial dna polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) assay was used to assess the population structure and genetic relationships among six persian sturgeon, acipenser persicus populations from south caspian sea along the iranian coast. the complete nucleotide dehydrogenase subunit 5 (nadh 5) region of mtdna amplified by pcr was di...

histopathological and pathomorphological effects of 15 ppb mercuric chloride on persian sturgeon, acipenser persicus, were investigated using histological and electron microscopy observations. light microscopy showed that the gill epithelial hypertrophy, wrinkling and hyperplasia in lamellar epithelia and lamellae fusion occurred after 48 h of exposure. gill epithelia also showed occasional nec...

Twelve species of the genus Ophiomorus DUMÉRIL & BIBRON, 1839 have been identified and introduced so far seven this found in Iran which include four endemic three nonendemic species. Although geometric morphometry is a powerful tool to analyze morphological changes, discovery identification these long relied on traditional morphometric analysis. In study, analyses were used determine morphometr...

Seventy-six helmeted guineafowls (Numida meleagris) were shot in the Andries Vosloo Kudu Reserve and on an adjacent farm in the eastern Cape Province during the period May 1985 to January 1987 and their tick burdens determined. A total of 10 ixodid tick species were recovered, of which Amblyomma hebraeum, Amblyomma marmoreum and Haemaphysalis silacea were the most abundant. The seasonal abundan...

Karyotype study was performed across 7 populations of 4 Rubus species growing in Iran. The results showed that the chromosome numbers of R. sanctus (2n=2x=14) diploid, R. caesius, and R. discolor were (2n=4x=28) tetraploids, R. persicus (2n=8x=56) octoploid. The chromosome numbers of R. discolor, and R. persicus were reported here for the first time. Karyotypic formula also varied between the s...

Climate change is expected to have an impact on the geographical distribution ranges of species. Endemic species and those with a restricted geographic range may be especially vulnerable. The Persian jird (Meriones persicus) endemic rodent inhabiting mountainous areas Irano-Turanian region, where future desertification form threat In this study, modelling algorithm MaxEnt was used assess climat...

Extract of Echinops persicus is traditionally used for a long time in Iran for treatment of cough and constipation. This extract is produced by activity of bug (Situphilus spp.) on the plant. We documented its anti-tussive effect in rats in our previous study. The aim of this study was to assess the anti-ulcer effect of Echinops persicus in an animal model. In this study we evaluated anti-ulcer...
