Human impacts are occurring at many scales in natural systems. Introduction of invasive species and climate change effects are two mostly negative examples. Spatial pattern analysis provides the means to map and identify many important drivers of these changes. I will link local measures of interactions between plants and insects, including pollinators, to climate. To do this, interactions with dominant plant species will be measured in four major ecosystems - forests, mountains, deserts, and grasslands. In each, either invasive species or climate change effects are used to structure all experiments. Webs of environmental sensors will also be placed at all sites, and regional climate data will be derived from public sources. Taken together, these linked datasets will provide a powerful test of the capacity for local interactions to filter large human impacts. This research is important to managers, conservation biologists, and policy makers. If dominant or foundational plant species respond differently to climate or invasive species, the effects of our disturbances may be magnified or perhaps buffered in some instances. This is critical information needed to predict how our natural systems will respond to change. It will also advance community and spatial ecology by providing a general set of protocols for coupling local interactions to larger geographic processes. Linking measures of biotic interactions to climate is very novel, and including insects speaks to important ecosystem services such as pollination. Anticipated outcomes include training of 50 HQP with 5 PhD students and 2 postdocs, peer-reviewed publications in top journals, establishment of distributed long-term sites for monitoring change, and estimates of biodiversity in several important ecosystems. Canada will benefit from this research directly since human impacts will be measured in Ontario forests, mountains in BC, and grasslands in Southern Ontario. We will also benefit by demonstrating international leadership in applying spatial and geographic tools to better understanding ecology.

在自然系统中，人类的影响发生在许多尺度上。入侵物种的引入和气候变化的影响是两个主要的负面例子。空间格局分析提供了绘制和识别这些变化的许多重要驱动因素的方法。我将把当地衡量植物和昆虫(包括传粉者)之间相互作用的指标与气候联系起来。为此，将在四个主要生态系统-森林、山脉、沙漠和草原-衡量与优势植物物种的相互作用。在每个实验中，要么是入侵物种，要么是气候变化的影响被用来组织所有的实验。还将在所有地点放置环境传感器网络，并从公共来源获取区域气候数据。总而言之，这些相互关联的数据集将为地方互动过滤大规模人类影响的能力提供强大的测试。这项研究对管理者、保护生物学家和政策制定者都很重要。如果优势或基础植物物种对气候或入侵物种的反应不同，我们的干扰的影响可能会在某些情况下被放大或缓冲。这是预测我们的自然系统将如何应对变化所需的关键信息。它还将通过提供一套将地方互动与更大的地理过程相结合的通用协议来促进社区和空间生态。将生物相互作用的衡量标准与气候联系起来是非常新颖的，包括昆虫在内就意味着重要的生态系统服务，如授粉。预期成果包括培训50名HQP，5名博士生和2名博士后，在顶级期刊上发表同行评议的出版物，建立监测变化的分布式长期站点，以及对几个重要生态系统的生物多样性进行估计。加拿大将直接从这项研究中受益，因为人类影响将在安大略省的森林、卑诗省的山脉和安大略省南部的草原上进行测量。我们还将受益于展示在应用空间和地理工具更好地理解生态方面的国际领导地位。
