摘要

诱捕毛状体是原生雌性诱捕花的常见特征，被认为能与传粉者互动，促进花粉清除和坐果。在本研究中，我们通过实验测试了诱捕毛状体是否有利于诱捕花的雌雄功能。我们利用原生雌性的南美马兜铃（Aristolochia esperanzae）诱导花，观察了两种性功能的时间变化，并将它们与花的枯萎和诱导毛状体联系起来。接着，我们描述了与捕获、诱捕和释放传粉昆虫有关的诱捕毛状体特征。花朵在雌花期结束后枯萎，而诱捕毛状体在花粉呈现后数小时才枯萎，这促使传粉昆虫延迟离开，因此它们携带了花粉。诱捕毛状体的特征，如向管内的密度梯度、单向定向和表皮蜡质，可能是捕获和诱捕传粉昆虫的重要因素。这些结果表明，诱捕花中诱捕毛状体的进化和维持可能是通过来自两种性功能的选择压力实现的，并突出了它们在这一高度表型特化的授粉系统中的作用。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
