Abstract

The breeding behavior of free-ranging dogs (Canis familiaris) was studied in Newark New Jersey, in the summer of 1978 and the winter of 1978–1979. The presence of an estrous female in an area led to increased aggression and hierarchy formation among males as they congregated around the female and attempted to mate. Data on estrous group dynamics, as well as evidence for female mate-selection, were gathered.

Males were categorized as either familiar or unfamiliar to the female, based on the proximity of their home-range core areas. Familiarity appeared to be a critical factor in mating success, as unfamiliar males were never observed mating; they generally remained in the estrous group for shorter periods of time and suffered a disproportionate number of attacks in comparison to familiar males.

While the consequences of such mate-selection are not clear, it is suggested that the observed behavior may be a vestige from a monogamous ancestor in which long-term pair bonds and paternal care predispose the female to choose males about whom she has more information. A shift to promiscuity in domestic dogs should not imply indiscriminate mating.

自由放养的城市狗的社会组织。2发情群体和交配系统
本文于1978年夏季和1978 - 1979年冬季在美国新泽西州纽瓦克对自由放养犬(Canis familiaris)的繁殖行为进行了研究。当一个地区出现一只发情的雌性时,雄性会聚集在雌性周围,试图交配,从而导致攻击性和等级制度的形成。收集了发情群体动态的数据,以及雌性择偶的证据。男性被分类为熟悉或不熟悉的女性,基于接近他们的家庭范围核心区域。熟悉度似乎是交配成功的关键因素,因为不熟悉的雄性从未被观察到交配;它们通常在发情的群体中停留的时间较短,与熟悉的雄性相比,它们遭受的攻击次数不成比例。虽然这种择偶的结果尚不清楚,但有人认为,观察到的行为可能是一夫一妻制祖先的遗留物,在这种祖先中,长期的伴侣关系和父亲的照顾使雌性倾向于选择她了解更多的雄性。家养狗向滥交的转变不应该意味着不分青红皂白的交配。
