Currently there is great debate about whether monogamy and associated kinship is a key element in the evolution of cooperation. Monogamy leads to high levels of kinship when dispersal of young is delayed (allowing kin selection for altruistic behaviour and cooperative breeding). However, delayed dispersal also leads to stable social interactions with known group members (allowing reciprocation of helpful behaviours which may provide direct fitness). Most studies of cooperative breeders focus on monogamous kin-based cooperative groups, thus confounding mating system and cooperation. I study two species in which monogamy and kin-based cooperative breeding are not correlated. The long-term goal of my research program is to determine how kinship, mating system, and social stability within groups affect cooperation and conflict in group breeding birds.

目前，关于一夫一妻制和相关亲属关系是否是合作演变的关键因素，存在着很大的争论。一夫一妻制导致高水平的亲属关系时，分散的年轻人被推迟（允许亲属选择利他行为和合作繁殖）。然而，延迟分散也会导致与已知群体成员的稳定社会互动（允许互惠的有益行为，这可能提供直接的健身）。大多数关于合作育种者的研究都集中在一夫一妻制的亲属合作群体上，从而混淆了交配系统和合作。我研究了两个物种，其中一夫一妻制和亲属为基础的合作育种是不相关的。我的研究计划的长期目标是确定亲属关系，交配系统，以及群体内的社会稳定性如何影响群体繁殖鸟类的合作和冲突。
