【摘要】 1999年和 2 0 0 0年的 1 1～ 1 2月期间共记录了黑龙江东北虎林园 1 6对东北虎的 1 693次交配事件 ,对其中 1 1 92次成功的交配事件进行了分析 ,建立了东北虎的交配行为谱 ,记录了 1 6种个体行为和 7种社会行为。东北虎的交配持续期为 (6 5 0± 2 5 0 )d ,不同繁殖对的交配次数差异很大 ,最少为 49次 ,最多可达 1 1 3次 ,交配成功率为 70 41 %。东北虎的交配高峰出现在 8∶0 0～ 1 0∶0 0时和 1 6∶0 0～ 1 8∶0 0时。交配成功的次数在第 3～ 5d达到高峰 ,失败的次数在开始交配时最高 ,以后则逐渐降低。在将雌、雄虎赶入小围栏内的首次爬跨前东北虎需花费 (2 0 2 4± 1 2 85 )min的时间做准备 ,其后的各次爬跨与首次相似 ,只是花费时间大大缩短 ,且持续的时间相差很大 ,最短仅为 4 70s,最长则达 6 3 1min。交配后的休息过程同时也是下一次交配前的准备阶段。每次将雌、雄虎赶入小围栏内东北虎要连续进行 (9 40± 4 60 )次爬跨 ,整个交配过程持续 (1 2 67± 3 0 5 )min ,每次爬跨历时 (1 0 0 9± 5 45 )s。更多还原

【Abstract】 Observations on the mating behavior of Amur tigers were conducted in the Heilongjiang Amur tiger Park, Harbin between November and December in 1999 and 2000 Based on the analysis of 1?693 copulations involving 16 individuals, of which 1?192 succeeded, this paper presented an ethogram comprised of 16 individual behaviors and 7 social behaviors.Copulation typically occurred over a duration of (6 50±2 50)days. The mating frequency of different pairs varied greatly, from 49 to 113. Of these, the success rate was 70 41%. Resting after copulation typically preceded further mating activity. The peak of copulation periods occurred between 8∶00-10∶00 and 16∶00- 18∶00. The frequency of successful copulation peaked after three to five days of copulation. The frequency of unsuccessful copulation was higher during the initial days of mating, declining gradually thereafter. Before the first copulation, Amur tigers spent(20 24±12 85)minutes preparing for mating. Each subsequent mounting was similar to the first one. The duration of each mounting va ried greatly (from 4 70 seconds to 6 31?minutes). Each mating bout involved an average of (9 40± 4 60) copulations with an entire bout lasting for (12 67±3 05)?minutes. Each mounting was (10 09±5 45) seconds.更多还原
