Grad student Stepfanie Aguillon’s newest paper is now out in the journal PLOS Genetics<\/a> — where it was released just 1.5 hours before she gave a talk on it at the AOS conference at Michigan State. The paper titled “Deconstructing isolation-by-distance: The genomic consequences of limited dispersal” shows how the movements of individual scrub-jays mediates patterns of genetic variation at very small spatial scales.<\/p>\n

Abstract–Geographically limited dispersal can shape genetic population structure and result in a correlation between genetic and geographic distance, commonly called isolation-by-distance. Despite the prevalence of isolation-by-distance in nature, to date few studies have empirically demonstrated the processes that generate this pattern, largely because few populations have direct measures of individual dispersal and pedigree information. Intensive, longterm demographic studies and exhaustive genomic surveys in the Florida Scrub-Jay (Aphelocoma<\/em> coerulescens<\/em>) provide an excellent opportunity to investigate the influence of dispersal on genetic structure. Here, we used a panel of genome-wide SNPs and extensive pedigree information to explore the role of limited dispersal in shaping patterns of isolationby- distance in both sexes, and at an exceedingly fine spatial scale (within ~10 km). Isolation- by-distance patterns were stronger in male-male and male-female comparisons than in female-female comparisons, consistent with observed differences in dispersal propensity between the sexes. Using the pedigree, we demonstrated how various genealogical relationships contribute to fine-scale isolation-by-distance. Simulations using field-observed distributions of male and female natal dispersal distances showed good agreement with the distribution of geographic distances between breeding individuals of different pedigree relationship classes. Furthermore, we built coalescent simulations parameterized by the observed dispersal curve, population density, and immigration rate, and showed how incorporating these extensions to Male\u00b4 cot\u2019s theory of isolation-by-distance allows us to accurately reconstruct observed sex-specific isolation-by-distance patterns in autosomal and Zlinked SNPs. Therefore, patterns of fine-scale isolation-by-distance in the Florida Scrub-Jay can be well understood as a result of limited dispersal over contemporary timescales.<\/p>\n
