摘要

1. 族群s that expand their range can undergo rapid 演化ary 適應 of life-history traits, dispersal behaviour and 適應 to the local environment. Such 適應 may be aided or hindered by sexual reproduction, depending on the context. 2. However, few empirical and experimental studies have investigated the 遺傳 basis of adaptive 演化 during range expansions. Even less attention has been given to the question how sexual reproduction may modulate such adaptive 演化 during range expansions. 3. We here studied genomic 適應 during experimental range expansions of the protist Tetrahymena thermophila in landscapes with a uniform environment or a pH gradient. Specifically, we investigated two aspects of genomic 適應 during range expansion. First, we investigated adaptive 遺傳 change in terms of the underlying numbers of allel
