摘 要：Color polymorphism offers rich opportunities for studying the eco-evolutionary mechanisms that drive the adaptations of local populations to heterogeneous and changing *** explored the color morph diversity and composition in a Chrysomela lapponica leaf beetle across its entire distribution range to test the hypothesis that environmental and climatic variables shape spatiotemporal variation in the phenotypic structure of a polymorphic *** obtained information on 13617 specimens of this beetle from museums,private collections,and *** specimens(collected from 1830-2020)originated from 959 localities spanning 33°latitude,178°longitude,and 4200 m *** classified the beetles into five color morphs and searched for environmental factors that could explain the variation in the level of polymorphism(quantified by the Shannon diversity index)and in the relative frequencies of individual color *** highest level of polymorphism was found at high latitudes and *** color morphs differed in their climatic requirements;composition of colour morphs was independent of the geographic distance that separated populations but changed with collection year,longitude,mean July temperature and betweenyear temperature *** proportion of melanic beetles,in line with the thermal melanism hypothesis,increased with increasing latitude and altitude and decreased with increasing climate *** morph frequencies also declined during the past century,but only at high latitudes and altitudes where recent climate warming was especially *** observed patterns suggest that color polymorphism is especially advantageous for populations inhabiting unpredictable environments,presumably due to the different climatic requirements of coexisting color morphs.
