A pair of Ehiopian grass frogs (Ptychadena nana) on the cover of PNAS this week!

Happy to share that our paper on the #evolution and #genomics of the most common #color polymorphism in #frogs is now out in @pnas.org! My favorite frogs even made the cover of this week’s issue! πŸŽ‰πŸΈπŸŽ‰

Read the paper here: www.pnas.org/doi/10.1073/...

Some species had an outsized role in shaping evolutionary theory. The Fiji Whistlers featured heavily in Ernst Mayr's development of the biological species concept and its application to allopatric taxa. In our new paper, we revisited this system with genomic data 🧡

Like woodpeckers? Or population genomics? Or three-species hybridization? Or selective sweeps?

Then this is for you!

The typeset version of "Evidence for ancient selective sweeps followed by differentiation among three species of Sphyrapicus sapsuckers" is published today:

Figure 1A from the paper shows the distribution of black-headed (western) and rose-breasted grosbeaks (eastern) throughout North America. Small illustrations of males of each species are shown. Black-headed has a rusty orange breast and black head, while rose-breasted has a small reddish bib with a bright white belly. There is an inset map of South Dakota showing the transect across the hybrid zone

The first Aguillon Lab paper is officially out in early view at Evolution!! Led by postdoc @devonderaad.bsky.social, we’ve explored the hybrid zone between black-headed and rose-breasted grosbeaks in the Great Plains. #ornithology #hybridization #speciation #evolution doi.org/10.1093/evol...

triangulaR: an R package for identifying AIMs and building triangle plots using SNP data from hybrid zones - Heredity Heredity - triangulaR: an R package for identifying AIMs and building triangle plots using SNP data from hybrid zones

The paper for my R package is published! This has been a fun process learning more about hybrid zones and triangle plots. Thanks everyone who has contributed and tested it out already!

SNPfiltR: Interactively Filter SNP Datasets Is designed to interactively and reproducibly visualize and filter SNP (single-nucleotide polymorphism) datasets. This R-based implementation of SNP and genotype filters facilitates an interactive and...

After a brief hiatus, the R package SNPfiltR is back on CRAN for easy installation (cran.r-project.org/web/packages...). Be sure to check out the documentation (devonderaad.github.io/SNPfiltR/ind...) to get ideas for the visualizations and filters you can use to better understand your SNP datasets!
