Seasonal aspects of social behavior and sex @entity134 levels were observed in two groups of @entity2608 from March through December. One group (3 males, 7 females) had lived outdoors for several years. The other group (6 males, 5 females), transferred outdoors in late February, had lived indoors for several years. In March-April, the long-term outdoor residents displayed the expected seasonal pattern of sexual behavior, characterized by absence of complete sequences of @entity146 . At this time the indoor-adapted group displayed high levels of @entity146 . Thereafter, frequencies of sexual behavior of the two groups were similar. @entity251 in the males was positively correlated with frequency of sexual behavior in each group. Females in the indoor-adapted group displaced menstrual cycles in March and April and 3 of 5 became pregnant at this time. The two remaining indoor-adapted females continued to display ovulatory cycles, but little sexual behavior, throughout the summer. Interestingly, two females in the outdoor-adapted group also displayed summer ovulatory cycles; without concomitant sexual activity. These data show that the disruption of seasonal breeding patterns produced by lengthy indoor housing remains briefly apparent following transfer outdoors, but is substantially overcome within a few months.

Resumption of seasonal breeding patterns in male and female XXXX transferred from an indoor to an outdoor environment.
