在纬度50?-55？在加拿大马尼托巴省，红边吊袜带蛇（Thamnophis sirtalis parietalis）在四月底或五月初出现后不久，以几千条个体的集中聚集冬眠并交配。当气温高于15摄氏度时，交配最为激烈，持续约4周。在实验室可通过以下方法诱导交配活动：1)9月在冬眠地收集蛇，在5℃，OL24D环境中放置至少4个月，然后转移到25℃，ol12d环境中；2)在四月底或五月初到冬眠地收集蛇，将其置于摄氏5度（零下24度），并随时转移到摄氏25度（零下12度），直到八月。食物摄取量在转移后的3天内被完全抑制，然后逐渐增加，与交配活动的下降成反比。从5c， OL24D转移到5c， 12L12D不会导致交配。在这些实验的基础上，我们假设红边袜带蛇在冬眠中出现时体温的升高导致了在出现后不久观察到的强烈交配活动。
At latitudes of about 50?-55? N in Manitoba, Canada, the red-sided garter snake (Thamnophis sirtalis parietalis) hibernates in concentrated aggregations of several thousand individuals and mates shortly following emergence in late April or early May. Mating is most intense when air temperatures are above 15 C, and lasts about 4 weeks. Mating activity of about 10 days duration can be induced in the laboratory by: 1) collecting snakes at the hibernaculum site in September, subjecting them to 5 C, OL24D for at least 4 months and then transferring them to 25 C, 12L12D; and 2) collecting snakes at the hibernaculum site in late April or early May, holding them at 5 C, OL24D, and transferring them to 25 C, 12L12D at any time until August. Food intake is completely inhibited for 3 days following the transfer, and then increases progressively in an inverse relationship to declining mating activity. A transfer from 5 C, OL24D to 5 C, 12L12D does not result in mating. On the basis of these experiments we hypothesize that the increase in body temperature experienced by the red-sided garter snake during emergence from hibernation induces the intense mating activity observed shortly following emergence.
