Population studies on gerbils of the western desert of Egypt, with special reference to Gerbillus andersoni DE Winton


Population studies on the gerbil, Gerbillus andersoni, were carried out in Omayed in the Western Desert of Egypt during the period from July 1976 through August 1978 inclusive. Studies included determination of the sex ratio in the different age and weight groups, as well as seasonal changes in this ratio. The mean weight and age at the onset of maturity and the reproductive activity of both sexes were determined. The study also included seasonal changes in mean body weights of both sexes, those of the testes in relation to body weights, as well as changes in the length of the testis and of the cauda epididymis. Changes in the age structure of the population were also studied.
