Abstract

The temporal pattern of breeding in populations is often characterized by a pronounced temporal clustering of births, flowering or seed set. It has long been suspected that this phenomenon is not caused by climatic seasonality alone but that reproductive synchrony represents a strategy that individuals adopt to maximize reproductive success. The classical hypotheses predicting an adaptive advantage of reproductive synchrony incorporate both sociobiological and ecological explanations. However, new theoretical and empirical analyses have shown that the predicted advantage of reproductive synchrony depends on the ecological setting in which populations reproduce, and processes earlier thought to be responsible only for synchrony may under some ecological conditions lead to asynchronous reproduction being the best strategy.

摘要

种群的繁殖时间模式通常表现为出生、开花或种子形成的明显时间聚集。长期以来,人们一直怀疑这种现象不仅仅是由气候季节性引起的,而是生殖同步代表了个体为最大限度地提高繁殖成功率而采取的一种策略。预测生殖同步具有适应性优势的经典假说包含了社会生物学和生态学解释。然而,新的理论和实证分析表明,生殖同步的预测优势取决于种群繁殖的生态环境,而以前被认为只负责同步的过程在某些生态条件下可能导致异步繁殖成为最佳策略。
