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 …

The gut microbiome plays an essential role in the overall health of organisms. However, the presence and abundance of these microbes may be altered by environmental factors, such as exposure to pesticides. The goals of this project were to understand 1) the prevalence of pesticide residues in honey bees in eastern Washington, and 2) the impact of pesticides to the honey bee gut microbiome. Accordingly, we tested bees from 24 hives among six sites across eastern Washington. High-performance liquid chromatography-mass spectrometry (HPLC-MS) was used to detect the presence and concentration of six commonly used agricultural pesticides: Carbaryl, Chlorpyrifos, Coumaphos, Cypermethrin, …
