Abstract: There are now many beautiful examples of phenotypic evolution on ecological timescales. Nevertheless, technological challenges and limited availability of temporal genomic data have left a large gap in knowledge of short-term evolutionary dynamics at the genomic level. Here, we investigate the evolution of natural populations on short timescales using a 25-year genomic, phenotypic, and pedigree dataset in the Florida Scrub-Jay. We use the population pedigree to directly characterize different evolutionary processes shaping short-term allele frequency change, and we test for selection over specific life-cycle stages.
