Alexis Garretson is a National Science Foundation Graduate Research Fellow and Predoctoral Student at Tufts University and The Jackson Laboratory joint program in Mammalian Genetics. Her Ph.D. research in the Dumont Lab focuses on using genetically diverse mouse strains to investigate the causes and consequences of mutation rate variation in populations. She previously completed a M.S. degree in Evolutionary Biology at George Mason University with Dr. Rebecca Forkner using citizen science data and herbarium specimens to investigate the fall color change. She advocates for open data as an Open Biodiversity Data Ambassador with the Global Biodiversity Information Facilities and a Champion with the National Microbiome Data Collaborative. Alexis has also been involved in bioinformatics and data science education as an instructor with The Carpentries and through developing university data science curriculum.

We find significant changes in the timing fall color change using herbarium specimens
We discuss the potential roles of hybridization in terms of generating asexuality and novel morphological traits in lichens. Our results highlight the need for additional study of reticulate phylogenies when investigating species boundaries and evolutionary history, even in cases with well-supported topologies inferred from genome-scale data.
