Abstract
The proposed research addresses a lack of quantitative models that can link data on landscape pattern and gene flow in natural populations. Because current landscape connectivity models focus on dispersal but not emergent patterns of gene flow, they are unable to take advantage of a growing number of population genetic datasets for validation, and cannot predict genetic effects of landscape change. Similarly, population genetic models either ignore spatial heterogeneity or suffer from prohibitive data and/or computational requirements. I propose to develop models which borrow computationally efficient algorithms from circuit theory to bridge geographic and genetic data and predict effects of landscape pattern on genetic structuring in natural populations.
