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...

this study was carried out to evaluate the effect of commercial live bakery’s’ yeast( saccharomyces cerevisiae ), (marketed as amax), on growth and survival of persian sturgeon( acipenser persicus) larvae (74.9 ± 9.7mg) during 30 days. sturgeon larvae were fed on daphnia magna enriched at three suspensions of yeast, amax, (0, 50, 100, and 150 mg yeast per litter). the feeding level was 30 perce...

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...
