- Intraspecific variation in vertebral number is taxonomically widespread. Much scientific attention hasbeen directed towards understanding patterns of variation in vertebral number among individualsand between populations, particularly across large spatial scales and in structured environments.However, the relative role of genes, plasticity, selection, and drift as drivers of individual variation andpopulation differentiation remains unknown for most systems. Here, we report on patterns, causesand consequences of variation in vertebral number among and within sympatric subpopulations ofpike (Esox lucius). Vertebral number differed among subpopulations, and common garden experimentsindicated that this reflected genetic differences. A QST-FST comparison suggested that populationdifferences represented local adaptations driven by divergent selection. Associations with fitness traitsfurther indicated that vertebral counts were influenced both by stabilizing and directional selectionwithin populations. Overall, our study enhances the understanding of adaptive variation, which iscritical for the maintenance of intraspecific diversity and species conservation.
