人类活动通过改变环境条件影响动物的择偶。这是由于对以下方面的影响：（i）择偶者对性状的评价和表达;（ii）向择偶者传递关于潜在配偶的信息;（iii）择偶者对信息的接收和处理;（iv）最终的择偶。在这里，我首先讨论这四个阶段的择偶过程可以改变环境的变化，以及如何这些变化，反过来，可以影响个人，人口和社区。有很多证据表明，人类引起的环境变化会影响配偶选择，但对求爱者和选择者的适应性的影响却鲜为人知，对种群动态、物种相互作用和群落组成的影响更是知之甚少。有更多的证据表明，改变择偶系统影响种间交配，从而影响群落组成和生物多样性。然后，我考虑塑料调整和进化的变化是否可以拯救自适应择偶系统，并反映在环境变化下的非适应择偶系统变得不那么适应的可能性。有很多证据表明，择偶系统会发生可塑性调整，但这些调整是否具有适应性，以及基因变化的作用，却鲜为人知。最后，我考虑了配偶选择系统在不断变化的环境中拯救种群的可能性。我解释了这是如何依赖于积极和消极的结果都可能。总之，虽然有很多证据表明人类引起的环境变化影响择偶系统，但对生态和进化过程的后果知之甚少。考虑到择偶在决定个体适应度和种群生存能力方面的重要性，在研究人类干扰生境的生态和进化后果时，应考虑环境变化对择偶系统的影响。
Human activities by altering environmental conditions are influencing the mate choice of animals. This is by impacts on: (i) the production and expression of traits evaluated by mate choosers; (ii) the transmission of information about potential mates to choosers; (iii) the reception and processing of the information by choosers; and (iv) the final mate choice. Here, I first discuss how these four stages of the mate-choice process can be altered by environmental change, and how these alterations, in turn, can influence individuals, populations, and communities. Much evidence exists for human-induced environmental changes influencing mate choice, but the consequences for the fitness of courters and choosers are less well known, and even less is known about the impact on population dynamics, species interactions and community composition. More evidence exists for altered mate-choice systems influencing interspecific matings and thereby community composition and biodiversity. I then consider whether plastic adjustments and evolutionary changes can rescue adaptive mate-choice systems, and reflect on the possibility of non-adaptive mate-choice systems becoming less maladaptive under environmental change. Much evidence exists for plastic adjustments of mate-choice systems, but whether these are adaptive is seldom known, as is the contribution of genetic changes. Finally, I contemplate the possibility of mate-choice systems rescuing populations from decline in changing environments. I explain how this is context dependent with both positive and negative outcomes possible. In summary, while much evidence exists for human-induced environmental changes influencing mate-choice systems, less is known about the consequences for ecological and evolutionary processes. Considering the importance that mate choice plays in determining individual fitness and population viability, the effects of environmental change on mate-choice systems should be considered in studies on the ecological and evolutionary consequences of human disturbances to habitats.
