Abstract: 

While conducting a research project "Biosystematic study of species of Spermophilus fulvus in Zanjan province” the morphological and biological characteristics of this species were also studied. Thus 72 living samples (45 male and 27female) were trapped in 4 research sites in various areas in Zanjan province (Zanjan, Sultaniyeh, Abhar and kidar). Morphological characteristics used in this study included: Total length, body and head length, tail length, hind foot length, ear length (mm) and total weight (gr).
The morphometric results obtained by studying these characteristics indicated that, the male samples except for their tail length were larger than females. When sexually matured, male animals tend to have a darker color than female ones. In the biological studies, the developmental growth of the animals from birth to maturity was studied, also increase in daily food intake until the beginning of hibernation (AUG 44gr) as well as decrease in food intake during hibernation (OCT-26gr, NOV-4.5gr and DEC-0.gr) was investigated. The longest and shortest hibernation bouts of ground squirrels were found to be 150 and 107 days respectively. In this period, the longest uninterrupted hibernation was 13 days. These samples reproduced twice a year (MAR. and JUN.) and also giving birth to 5-7 babies each time.
