尽管扩散通常被认为是任何生物体适应性的关键决定因素，但我们对它在植物种群持续和扩散中的作用的理解仍然不完整。由于种子传播的背景依赖性、环境异质性和多个时空尺度上相互依赖的过程，推广和预测传播过程具有挑战性。目前的人口模型往往使用简单的扩散过程的现象学描述，限制了他们的能力，以检查人口的持久性和传播的作用，特别是在全球变化。为了推动种子传播生态学的发展，我们需要评估任何单一种子传播事件在植物生活史和环境变化的完整时空背景下的影响，这些变化最终会影响种群的持续和传播能力。从这个角度来看，我们提供了整合的经验和理论方法，占种子传播的上下文依赖性，以提高我们的能力，概括和预测的后果，传播，其人为的改变，跨系统的指导。我们为这项工作合成合适的理论框架，并讨论来自不同子学科的概念，方法和可用数据，以帮助操作概念，突出跨研究领域的最新突破，并讨论持续的挑战和开放的问题。我们解决知识差距的运动生态学的种子和传播和人口的整合，可以受益于这样一个综合。通过跨学科的视角，我们将能够更好地了解全球变化将如何影响种子传播过程，以及对植物种群持久性，传播和生物多样性的潜在级联效应。
Although dispersal is generally viewed as a crucial determinant for the fitness of any organism, our understanding of its role in the persistence and spread of plant populations remains incomplete. Generalizing and predicting dispersal processes are challenging due to context dependence of seed dispersal, environmental heterogeneity and interdependent processes occurring over multiple spatial and temporal scales. Current population models often use simple phenomenological descriptions of dispersal processes, limiting their ability to examine the role of population persistence and spread, especially under global change. To move seed dispersal ecology forward, we need to evaluate the impact of any single seed dispersal event within the full spatial and temporal context of a plant's life history and environmental variability that ultimately influences a population's ability to persist and spread. In this perspective, we provide guidance on integrating empirical and theoretical approaches that account for the context dependency of seed dispersal to improve our ability to generalize and predict the consequences of dispersal, and its anthropogenic alteration, across systems. We synthesize suitable theoretical frameworks for this work and discuss concepts, approaches and available data from diverse subdisciplines to help operationalize concepts, highlight recent breakthroughs across research areas and discuss ongoing challenges and open questions. We address knowledge gaps in the movement ecology of seeds and the integration of dispersal and demography that could benefit from such a synthesis. With an interdisciplinary perspective, we will be able to better understand how global change will impact seed dispersal processes, and potential cascading effects on plant population persistence, spread and biodiversity.
