Dispersion and Morphometry of Amphibians of Lavasanat in tehran

Amphibians are animals which spend a part of their life in aquatic and the other parts in terrestrial ecosystems. Sampling was performed at 8 major sites of Lavasanat district during spring and summer of 2014 using handle fishing net in a randomly method. Results showed that one species of frog Pelophylax ridibunda ridibunda and one species of toad, Pseudepidalea viridis viridis were living in the district. Results of the effects of sampling site on population dispersion showed that there was a significant differences for the population of (p<0.05), but the population dispersion of Pseudepidalea viridis viridiswas not affected by the sampling site (p>0.05). Results of the effects of sampling timeon population dispersion showed that there were no significant differences in the both detected species (p>0.05). Different morphometric characteristics were significantly affected by the site and time of sampling (P<0.01). Results also showed that the morphometric amounts characteristics of females were higher than males and differences were significant (p<0.05), the species was significantly affected the differences between different morphometric characteristics (p<0.05).
