Data and code from: Impacts of urbanization on pathogens and pests of wild and cultivated plants

Understanding how urbanization affects plant interactions with pathogens and herbivores is important for clarifying how changes in land use, climate, and biodiversity affect ecological and evolutionary processes, and for managing urban plants to maximize ecosystem services. We performed a systematic literature review of relationships between urbanization and pathogens or pests of wild and cultivated plants. We identified k = 171 relationships from n = 54 studies in which pathogen or pest abundance was quantified in both urban and non-urban areas, and summarized their distribution across taxa, geographic regions, and directions and mechanisms of effects proposed by the authors. Most studies featured tree hosts and their arthropod pests or fungal pathogens. Grasses and forbs were the next most commonly studied hosts, followed by crops and shrubs. We then performed a meta-analysis limited to trees, which had the most studies with sufficient statistical information (k = 55 relationships, n ..., , # Data and code from: Impacts of urbanization on pathogens and pests of wild and cultivated plants
