Abstract :
Many biological studies require the estimation of population density or population size are also needed to determine the size of specimens of species distribution pattern is used. So the purpose of this study that on the mountain racerunner at Alvand heights such as accepted, determine the density and distribution pattern .this species is Thus only within a small Zagros Mountains in the provinces of Kermanshah and Hamadan has been reported, and a species is considered native to Iran. In this study, that from April to October 2010 while starting activity species after hibernation done, the study area to two A and B share .was the exact density of these methods line transect using the Hine estimate respectively 16.9 and 20.1 individuals per hectare and the estimated population of this species respectively 725 and 321 individuals was calculated. the most important factors in the difference density such Among areas of plant density, the pores and gaps, bait needed, slope and elevation was determined, the pattern of distribution of this species using chi-squared random obtained, using plot and test index of dispersion, chi-squared goodness of fitness and G-test of Williams distribution pattern cavities and prey was Random and distribution pattern plants was pile.
