Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, EarlyView.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.
