Pegan & Winger tested whether inversions are common within populations without phenotypic polymorphisms in 28 N. American bird species, finding that many polymorphisms are present at balanced frequencies, but possibly segregating neutrally.

GBE | Large Inversion Polymorphisms are Widespread in North American Songbirds The Yellow-bellied Flycatcher (Empidonax flaviventris) is a North American migratory bird species whose nondescript exterior conceals dramatic genomic polymorphisms, including the putative inversion highlighted on the upper left in elevated orange points. Population genomic data from across the species’ breeding range revealed that this large 57-Mb region produces PCA plots with a distinctive 3-cluster pattern (upper right), not present in other parts of the chromosome (lower left). The middle cluster in the 3-cluster PCA corresponds to individuals heterozygous for the polymorphism, while the other two clusters represent the two classes of homozygotes. Pegan & Winger (2025) used whole genome data to find that evidence for large inversion polymorphisms is common even in species that lack known external phenotypic variation, which is frequently associated with inversions in studies on avian genomics. The depicted polymorphism is one of 170 identified across 28 species. Photo: Georg Langebrake.

@jdmanthey.bsky.social, Associate Professor @ttu.edu, combines fieldwork, labwork, genomics, and bioinformatics to study fundamental questions in evolution and ecology, largely focused on diversification of taxa in fragmented habitats, including islands and “sky islands” like the Ethiopian Highlands
GBE author spotlight: Joseph D. Manthey. Dr. Joseph D. Manthey is an Associate Professor in the Department of Biological Sciences at Texas Tech University. His research group uses a combination of fieldwork, labwork, genomics, and bioinformatics to study fundamental questions in evolutionary biology and ecology. Manthey's research explores how organisms evolve across both geographic and genomic landscapes, with a focus on birds and ants. His work on speciation and diversification is largely focused on taxa in fragmented habitats, including islands and “sky island” systems like the Ethiopian Highlands. His work on genome evolution has included how genomic architecture—such as transposable elements or chromosome size—impacts variation in genomic diversity within and between species.
