Rates and trajectories were strongly influenced by habitat, trophic guild, and demographic processes. Forest, open-habitat, and wetland assemblages tracked warming faster than urban or farmland communities. Colonization of warm-affinity species and extinction of cold-affinity species emerged as key mechanisms driving change. High baseline diversity negatively related to the rates of thermophilisation.
