Overview

Meta-analysis analyzes spatial variation in directional selection, showing strength differences among populations, highlighting future research needs.

Key Points

  • This research aims to understand how spatial variations affect directional phenotypic selection among populations.
  • Analyzed data from 60 spatially replicated studies on directional phenotypic selection.
  • Included 3937 estimates of selection from an average of five populations per study.
  • Performed meta-analyses to investigate spatial variation features.
  • Found that selection primarily varies in strength across populations, less in direction.
  • Observed differences in selection direction mostly where selection is weakest, limiting adaptive divergence.
  • Noted spatial selection variation comparable to annual temporal variation, despite data deficiencies.
