This action funds an NSF Postdoctoral Research Fellowship in Biology for FY 2025. The fellowship supports research and training of the fellow that will contribute to biology in innovative ways. Habitat destruction and landscape change can cause populations to decline, reducing genetic variation and increasing extinction risk. One mechanism to help endangered populations survive is through gene flow, when individuals from other populations introduce new genetic variation, potentially boosting genetic diversity and lowering extinction risk. However, the relative importance of key factors driving gene flow such as distance, social dynamics, and population size, are not well understood. In addition, the effects of gene flow on traits, survival, and future population growth remain unclear, as the effects of gene flow can be beneficial, harmful, or even change over time. This project combines genomic, trait, life cycle, and environmental data to improve our understanding of the impacts of gene flow across multiple scales and over time. The goal is to provide useful insights for conservation efforts and help predict future outcomes for at-risk populations. As part of this project, the fellow will create educational materials to teach bioinformatics, making complex genetic concepts and skills more accessible. Gene flow shapes geographic patterns in genotypes, phenotypes, fitness, and population dynamics. This project investigates the multigenerational impacts of gene flow in a wil
