Comparison of Conservation Strategies for California Channel Island Oak (<i>Quercus tomentella</i>) Using Climate Suitability Predicted From Genomic Data.

ABSTRACT: Management strategies, such as assisted gene flow, can increase resilience to climate change in tree populations. Knowledge of evolutionary history and genetic structure of species are needed to assess the risks and benefits of different strategies. Quercus tomentella, or Island Oak, is a rare oak restricted to six Channel Islands in California, United States, and Baja California, Mexico. Previous work has shown that Island Oaks on each island are genetically differentiated, but it is unclear whether assisted gene flow could enable populations to tolerate future climates. We performed whole-genome sequencing on Island Oak individuals and Q. chrysolepis, a closely related species that hybridizes with Island Oak (127 total), to characterize genetic structure and introgression a
