European butterfly populations vary in sensitivity to weather across their geographical ranges

Aim The aim was to assess the sensitivity of butterfly population dynamics to variation in weather conditions across their geographical ranges, relative to sensitivity to density dependence, and determine whether sensitivity is greater towards latitudinal range margins. Location Europe. Time period 1980–2014. Major taxa studied Butterflies. Methods We use long‐term (35 years) butterfly monitoring data from > 900 sites, ranging from Finland to...
