Abstract

Podoces pleskei is from crow family and belongs to the genus of  ravens land or runners. The distribution of this species in Iran to isolated patches in desert and semi-desert areas that is limited to Central and East of Iran .There are concerns because of the isolation of populations that due to dangers such as inbreeding, genetic drift and so etc. The aime of this study is to compare some morphological characteristics of isolated populations of Podoces pleskei in the provinces of Semnan and Yazd. For this purpose, eight morphological variables were choose from foot and mouth organs for 21 chickens in the Marvast Herat region in Yazd province and four numbers of chickens measure from Protection Complex of Touran.Then all these data were standardized by dividing the cube root of body weight. To normalize these data were used the logarithm of deformation. Also,T-test was used to compare the measured variables between individuals of the populations of Marvast Herat of Yazd and Touran. The results showed that the chicks and adults in the two areas have significant differences in beak length and width variables. Also, the size and form of nutritional devices Podoces pleskei in these two areas have significant differences in the immature and mature which can be associated with diet and food habits search for them in these two areas and is also used as prey size that demands complete studies for comparative study of diet and eating habits of the two provinces in different seasons.
