个体行为塑造了鸟类介导的种子传播模式

种子散播是植物生命周期中的一个关键环节，它使植物能够在新的栖息地生根发芽，并最终实现范围转移。对于动物散播的植物来说，散播种子的动物的行为会直接影响种子的命运。然而，关于动物个体行为如何影响种子传播的实证证据却很少。在这里，我们通过分析斑纹裂壳鸟（Nucifraga caryocatactes）在采收和散播瑞士石松（Pinus cembra）种子时的运动数据，研究了个体行为对种子散播距离和位置的影响。为了评估种子散播模式的个体差异，我们比较了不同个体白天每小时的位移模式。我们进一步确定了鸟类个体的种子贮藏地点，并分析了这些地点的松树再生潜力。我们发现胡枝子有两种不同的行为：短距离种子散播和长距离种子散播。这两种行为导致的瑞士石松再生潜力的缓存地点明显不同：短距离传播的种子缓存在高海拔地区，在松树当前栖息地内再生潜力高；而长距离传播的种子缓存在低海拔地区，在松树栖息地外再生潜力低。这些行为与鸟类的体重、相对翼长或性别无关。我们的研究结果强调，种子散播动物的种内个体行为会对生态系统功能产生深远影响。个体行为是种子传播动态的主要决定因素，因此应将个体行为考虑在内，以便更好地了解当前和未来环境条件下的生态系统功能。在期刊博客上免费阅读本文的通俗摘要。

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.
