Climatic adaptation and phylogenetic history shape the intra-specific variation of CSR strategies in a widespread grass.

ABSTRACT: The competitor, stress tolerator, and ruderal strategy (CSR) framework has been widely applied to explain ecological processes across species. However, its utility in revealing intra-specific trade-offs and genetic adaptation to climate remains unclear. In this study, we examined whether the CSR strategy estimated by leaf traits can identify adaptations to climate in the common reed Phragmites australis. For this purpose, we integrated functional trait data from field surveys and a three-year common garden experiment to compare CSR scores between two typical populations of P. australis from western and eastern China. We further assessed the associations of CSR scores with latitude, bioclimatic factors, and phylogeographical sources using a global dataset including two invaded
