Observations on the reproduction biology of Meriones meridianus Pallas, 1773 (Mammalia: Rodentia) in Turkey

Abstract The reproduction biology of Meriones meridianus was investigated in the field and laboratory. The distribution in Turkey is confined to a relatively small area in the extreme east of the country. The duration of pregnancy in uncontrolled laboratory conditions was found to last 24–27 days, and average birth weight to be 2.45 g. The litter size was determined to vary between 5 and 7 at birth. The breeding season of this species lasted from May to October. The development of body measurements during the postembryonal period is shown.
