 Our lab's work describing range-wide population genomics of the convergent lady beetle, Hippodamia convergens is now out in Evolutionary Applications! We describe the efficacy of using genotyping by sequencing techniques to assess the efficacy of augmentative biological control in the species, showing significant degree of population structure, no contemporary gene flow between Eastern US, Western US, and Chilean populations.

New manuscript on genome-wide adaptations for invasion success in Sesamia inferens now out!1/24/2024 Our new manuscript describing genome-wide adaptations to invasion in the pink rice borer, Sesamia inferens is now out in Insects. We use a combination of evolutionary population genomics and comparative analyses to estimate strong selection at insect cuticle glycine-rich cuticular protein genes which are associated with enhanced desiccation adaptability, and at the histone-lysine-N-methyltransferase gene associated with range expansion and local adaptation. Read here! Congrats to Scott Monahan and Ryan Buck on co-authoring this massive work!  |
