Erica, Robin Tinghitella and Scott Taylor have a new review on the impacts of climate change on temperature sensitive reproductive barriers in insects. Check out the open-access article in Frotiners of Ecology and Evolution (here)
Erica attended the Biology of Spermatozoa meeting in Nynäshamn, Sweden. As always, it was a great meeting! Information about this unique meeting is available HERE.
Our hybridizing Chrysochus beetles are featured on the cover of the Journal of Evolutionary Biology!
Erica’s review with Robin Tinghitella and Scott Taylor on insect hybridization and climate change is accepted at Frontiers Ecology and Evolution! Abstract here.
Amy is starting her PhD in the Larson Lab this fall. Welcome Amy!
Kelsie Hunnicutt just returned from a road trip to Montana, where she visited Jeff Good’s lab to learn mouse and hamster testes cell sorting. Kelsie collected a ton of data on her trip, and visited Yellowstone and Glacier on the way.
Congratulations to Brooke Washburn, who was awarded the R.C. Lewontin Early Award from the Society for the Study of Evolution! Read more here.
Congratulations to Kelsie who was just awarded a grant from Sigma Xi. Kelsie is using her grant to travel to Montana this summer to learn to sort testes cells for gene expression assays with Jeff Good’s lab.
Our Chrysochus hybrid zone paper was accepted at the Journal of Evolutionary Biology. We provide a direct link between cryptic barriers studied in the lab over a range of heterospecific mating frequencies, and hybrid zone dynamics.
Abigail Wallin and Uma Knaven both received Summer Research Awards. Congratulations and welcome!
Kelsie Hunnicutt received a Grant-in-Aid of Research Award from the American Society of Mammalogists!
Brooke Washburn just received a Theodore J. Cohn Research award!
The Larson Lab is collaborating with Scott Taylor and Nolan Kane at the University of Colorado Boulder to organize a graduate training workshop for visualizing large genomic datasets. So far, we have received funding from the American Genetics Association (Special Events Award) and the University of Colorado Boulder. More about information about the workshop will be available in the fall.
Visualizing Genomic Data Workshop
Complex datasets are hard to visualize, yet effective communication of results to both the scientific community and to the public requires clear visualization. The Visualizing Genomic Data Workshop will provide participants with the necessary skills and background to produce clear, effective, and attractive figures from their genomic data. Further, the workshop will act as a catalyst to help graduate students and postdocs within the greater Rocky Mountain area develop broad professional networks.
Our paper won the 2018 GENETICS Editors’ Choice Award for Population Genetics!
The Evolution of Polymorphic Hybrid Incompatibilities in House Mice

Reproductive barriers are often assumed to arise from fixed genetic differences between species, despite frequent individual variation in the strength of reproductive isolation between populations. Larson et al. report polymorphism at several hybrid male sterility loci in house mice, and their results demonstrate that selection against deleterious hybrid interactions can drive the introgression of hybrid incompatibilities, highlighting the need for more extensive sampling of natural variation in speciation studies.
Congratulations to Kelsie for being admitted to the Bodega Applied Phylogenetics Workshop at the University of California Davis!

The second installment of our collaboration with Peter Ellis' group to quantify sperm nuclear morphology in classic and wild mice. A great paper lead by Ben Skinner. Preprint
The DU Nature Challenge was a success! Despite cold weather, we still found a few Orthopterans.
