Ecosystem services (ES), the benefits that humans obtain from nature, are an increasingly important tool for environmental decision-making. ES science can lead to better management by enabling communities to undertake multifunctional planning with models that can forecast how changes in land use or management will affect the provision of multiple ES. But the promise of ES science has not been fully realized, in part due to limited empirical studies of ES interactions. In particular, current science on ES interactions tends to focus on one temporal and spatial scale at a time, an approach that overlooks the system dynamics that could elucidate the mechanisms behind ES interactions. A better understanding of the mechanisms behind ES interactions could help mangers enhance synergies and avoid tradeoffs. Thus, scientists have called for increased attention to multiple ES, and especially to studies across multiple temporal and spatial scales that can elucidate the mechanisms behind ES interactions. Research in my lab is centered on understanding the ecological mechanisms that underlie the provision of multiple ES and their interactions, primarily in agricultural landscapes. My research program focuses especially on enhancing methods for mapping and modelling ES interactions to ensure that they better reflect the nonlinearities, feedbacks, and legacies that are key features of the complex systems that provide ES. Over the next five years, my team and I will explore how ES can be better understood as the products of systems that are dynamic in both space and time, how models can be improved to reflect this knowledge, and what these more dynamic models of ES can tell us about planning for the long-term the resilience and sustainability of ecosystems. We will do this through three interlocking initiatives: (1) a global analysis of common ES interactions in the anthropogenic biomes of the world, (2) a multi-scale analysis of ES interactions in the Montérégie, a local system well-known to our lab; (3) an exploration of the role of temporal dynamics, time lags, and legacies in the provision of ES over 100 years of land use and management change in the Montérégie. Communities across Canada and around the world are struggling with resource management questions, especially in working landscapes such agricultural regions. Unfortunately, we are making key decisions in the absence of the information we need to effectively maintain provision of multiple, highly desirable ES across space and through time. The work that I am proposing to undertake in my research program has the potential help answer fundamental questions about management of natural resources now and in the future. Together, time, space, and feedbacks among system components are the unexplored areas of ES research; they hold the key to managing ecosystems for sustainability.

生态系统服务（ES），人类的好处是从自然中获得的，一种越来越重要的工具环境决策。或管理层尤其是ES相互作用的多个ES。更好地了解ES相互作用的机制可以帮助Mangers增强协同作用并避免折衷，因此，科学家呼吁增加对多个ES的关注，尤其是在多层次的时间和空间尺度上，可以阐明ES相互作用的机制在理解多重ES和互动的过程中，Y研究计划的原始景观尤其着重于增强建模的方法，以确保它们更好地反映非线性，并且可以更好地理解ES。在时空和时间上的动态eSE更具动态模型可以告诉我们有关生态系统的弹性和可持续性的计划，我们将执行三个三个互锁计划：（1）Montérégie中ES相互作用的Ulti级分析，我们的实验室众所周知的当地系统；不幸的是，在不存在信息的情况下，我们的决定是在苦苦挣扎的情况下。现在关于自然资源的基本问题和未来的空间。
