Genomic outcomes of hybridization depend on selection and recombination in hybrids. Whether these processes have similar effects on hybrid genome composition in contemporary hybrid zones versus ancient hybrid lineages is unknown. Here we show that patterns of introgression in a contemporary hybrid zone in Lycaeides butterflies predict patterns of ancestry in geographically adjacent, older hybrid populations. We find a particularly striking lack of ancestry from one of the hybridizing taxa, Lycaeides melissa, on the Z chromosome in both the old and contemporary hybrids. The same pattern of reduced L. melissa ancestry on the Z chromosome is seen in two …

Hart Prairie Preserve Site Visit To Assess Aspen Health Nature Conservancy, Flagstaff, Az, Amanda Grady
Aspen Bibliography
On June 11, 2018, Amanda Grady, Entomologist, Arizona Zone, Forest Health Protection, performed a site visit to evaluate aspen health on the Nature Conservancy lands at Heart Prairie Preserve (HPP) near Flagstaff. Specifically, the evaluation was to determine whether or not the aspen within exclosures on Fern Mountain have symptoms or signs of Oystershell scale (OSS), an emergent forest pest contributing to aspen decline in northern Arizona.
