Brandt's voles have an annual cycle of body weight and adiposity. These changes can be
induced in the laboratory by manipulation of photoperiod. In the present study, male captive-
bred Brandt's voles aged 35 days were acclimated to a short day (SD) photoperiod (8L: 16D)
for 70 days. A subgroup of individuals (n= 16) were implanted with transmitters to monitor
physical activity and body temperature. They were then randomly allocated into long day
(LD= 16L: 8D)(n= 19, 8 with transmitters) and SD (n= 18, 8 with transmitters) groups for an …
