Summary: | Understanding the effects of small- and large-scale processes on broad patterns in community organization is a major challenge in ecology. Local-scale species interactions can strongly influence community structure and dynamics; however, the strength and nature of interactions are dependent on environmental factors and the phenotypic traits of populations, which can both vary across broad spatial scales. Hence, exploring geographic variation in populations and species
interactions, particularly across environmental gradients, can inform our understanding of the mechanisms that influence local-scale processes and potentially shape ecological communities.
