野外猪獾(Arctonyx collaris)交配行为观察
|
摘要
2017年3月13日-5月13日,获得猪獾在野外交配的红外相机视频463个片段,总有效时长8 057 s。交配前雄兽对雌兽有明显看护行为,时间长达30. 55 h。4月18日01:55-08:49,雌兽在洞巢外接受了雄兽1次爬跨、3次交配,每次交配持续时间分别为:731 s、1 690 s、1 494 s,交配维持时间明显大于多数已知哺乳动物的交配时间。观察初步结果显示:1)猪獾的交配时机由雌兽掌握,雌兽对雄兽有明确的邀配(sexual solici-tations)行为; 2)在一个发情周期内,雌兽可接受同一雄性个体的多次交配; 3)雄兽交配过程中有快速、持久抽插的动作。这些交配策略,支持生殖刺激(Stimulation of reproduction)假说和护卫交配权(Mate guarding)假说。
463 videos( totally 8 057 s) about wild mating behavior of Hog-badger( Arctonyx collaris) were recorded by infrared camera during 2017 March 13 th to May 13 th in Jiangxi Wuyishan.Male care for females for 30. 55 h before mating. One mounting behavior,and three mating behaviors were observed outside the cave nest in April 18 th from 01: 55 to 08: 49. The duration of mating behavior lasted for 731 s,1 690 s and 1 494 s,respectively. Mating duration was significantly longer than that of most known mammals. Based on these observations,we found 1) the mating behavior was controlled by female,and there were obvious sexual solicitations from female; 2) Females can receive multiple mating of the same male individual within one estrous cycle; 3) Quickly and repeatedly pumping and inserting behavior was observed during mating. These mating strategies support the stimulation of reproduction hypothesis and mate guarding hypothesis.
