Data for "Effects of urbanization on local adaptation and eco-evolutionary feedbacks in white clover"

Data required for all analyses described in the paper “Effects of urbanization on selection, local adaptation, and eco-evolutionary feedbacks” (2025), testing how urban and rural environments affect the fitness and ecological interactions of white clover (Trifolium repens, L.; Fabaceae). Data is from a reciprocal transplant common garden experiment conducted in 2023 in the Greater Toronto Area, Canada using white clover from urban and rural populations and that either did or did not produce hydrogen cyanide (HCN). All analyses were conducted in R version 4.4.2 DATA FILES: 1. biomass_2023.csv contains dry end-of-season aboveground biomass data. Data Explanation: Source_Hab: Source population habitat of the white clover plant. U = urban (plant comes from an urban population), R = rural (plant comes from a rural population).
