Effective dispersal patterns in prairie plant species across human-modified landscapes

Effective dispersal among plant populations is dependent on vector behavior, landscape features, and availability of adequate habitats. To capture landscape feature effects on dispersal, studies must be conducted at scales reflecting single-generation dispersal events (meso-scale). Many studies are conducted at large-scales where genetic differentiation is due to dispersal occurring over multiple generations, making it difficult to interpret the effects of specific landscape features on vector behavior. Genetic structure at the meso-scale may be determined by ecological and evolutionary processes, such as the consequences of vector behavior on patterns of gene flow. We used chloroplast haplotypes and nuclear genome SNP surveys to identify landscape features influencing seed and pollen dispersal at a meso-scale within the Rogue River Valley in southern Oregon. We evaluated biotic and abiotic vector behavior by contrasting two annual species with differing dispersal mechanisms; Achyrachae..., , , # Effective dispersal patterns in prairie plant species across human-modified landscapes

## Description of the data and file structure

**Species_sampling_coordinates.csv**: CSV containing the species, population alpha-numeric code, sequencing type (chloroplast haplotypes, genotyping-by-sequencing, or both) and latitude-longitude coordinates.

**Amollis_cp_haplotype_population_frequencies.csv**: CSV containing the chloroplast haplotype frequencies by population for *Achyrachaena mollis*, as determined by the CallHap program. Each row is a population; each column is an identified haplotype. Values represent the number of individuals in the population with the haplotype.

**Pcongesta_cp_haplotype_population_frequencies.csv**: CSV containing the chloroplast haplotype frequencies by population for *Plectritis congesta*, as determined by the CallHap program. Each row is a population; each column is an identi...
