给出了一个理解和预测动物交配系统形式的生态学框架[一般行为策略]。潜在的假设是，与交配相关的性内互动基本上是竞争性的。受限制性别的个体成员被期望通过试图控制对受限制性别的配偶的访问来最大化其包容性适合度。实现这一目标的程度取决于与这种控制相关的成本和收益。某些环境因素，特别是关键资源的空间分散模式和接受配偶的时间可用性，是这些成本和收益的重要决定因素。个体垄断资源或配偶的可能性越大，性选择的强度就越大，一夫多妻制的环境潜力就越大。交配系统的确切形式将取决于限制的性别，以及有限的性别控制资源基础或垄断配偶(或两者兼而有之)的方式和程度。提出了交配系统的生态分类，使人们能够更好地理解形成一个交配系统而不是另一个交配系统的选择性力量。在这个生态框架内，讨论了从LEK的发生到一夫多妻制的进化的具体例子。
An ecological framework for understanding and predicting the forms of animal mating systems [general behavioral strategy] is given. The underlying assumption is that intrasexual interactions associated with mating are basically competitive. An individual member of the limited sex is expected to maximize its inclusive fitness by attempting to control access to mates of the limiting sex. The degree to which this is possible depends on the costs and benefits associated with such control. Certain environmental factors, particularly the spatial dispersion pattern of key resources and the temporal availability of receptive mates, are important determinants of these costs and benefits. The greater the potential for individuals to monopolize resources or mates, the greater the intensity of sexual selection and the greater the environmental potential for polygamy. The precise form of the mating system will depend on which sex is limiting and on the manner and the degree to which the limited sex controls the resource base or monopolizes mates (or both). An ecological categorization of mating systems is presented that allows a better understanding of the selective forces shaping one mating system over another. Within this ecological framework, specific examples are discussed ranging from the occurrence of leks to the evolution of polyandry.
