主 题：common garden evolution of the increased competitive ability habitat productivity invasion latitudinal dines
摘 要：Aims Field and common garden comparisons are commonly performed to test the rapid evolution of increased vigor in introduced plant *** dines in phenotypic traits can obscure such evolutionary inferences,particularly when native or introduced populations are distributed across large geographic *** tested whether the latitudinal dines influence comparisons between introduced and native populations of Senecio *** Senecio vulgaris is native to Europe but has been introduced in northeastern and southwestern *** evaluate the performance in terms of growth and reproduction between native European populations and introduced Chinese populations,we compared plant height,number of branches and number of capitula in field populations in native and introduced ranges and in a common garden in *** Findings The introduced Chinese populations performed better than the native European populations in the field in terms of plant height and number of capitula,which was consistent with the prediction of the evolution of the increased competitive ability(EICA)*** Chinese populations produced more capitula than the European populations when the latitudinal cline was considered in the common garden *** we compared the traits of the northeastern Chinese,southwestern Chinese and European populations in both the field and common garden,the northeastern Chinese populations,at latitudes similar to those of the European populations,exhibited greater plant size and more capitula than the European populations in both the field and common ***,the southwestern Chinese populations,at latitudes much lower than those of the European populations,did not perform better than the native populations in terms of *** conclusion,our results suggest that latitudinal dines in phenotypic traits should be considered in field and common garden comparisons when introduced populations are geographically structur
