Daniel’s new MolEcol paper on chromosomal inversions in an Australian finch hybrid zone

A paper lead-authored by postdoc Daniel Hooper is out now in Molecular Ecology where you can read about how ‘Sex Chromosome Inversions Enforce Reproductive Isolation Across An Avian Hybrid Zone’. This paper, focused on the hybrid zone in northern Australia between subspecies of the long-tailed finch (Poephila acuticauda), is one…

Shawn on towhee hybrids at the International Ornithological Congress

At the IOC in Vancouver, Shawn presented a portion of his postdoctoral work from the lab, describing how genetic data were generated from museum specimens using the HyRAD protocol. These data were used to characterize a hybrid zone between Eastern and Spotted Towhees, which showed extensive genetic introgression and low…

Signals of Adaptive Introgression Between Saltmarsh and Nelson’s Sparrows

Postdoc Jen Walsh is the lead on a new study published in Evolution that leverages whole genome data from Saltmarsh and Nelson’s sparrows to investigate the genomic landscape of introgression between these species. By comparing populations in allopatry and sympatry, Jen’s paper shows that contemporary introgression is shaping the genomic…

Natalie on starlings at International Ornithological Congress

At the IOC this week PhD candidate Natalie Hoffmeister presented some of her work on the population genomics of European (Common) starlings. Her poster covered 1) genome-wide differentiation within North American starlings, and 2) evidence for local adaptation within starling invasions in Australia and the U.S. This work is part…

Even sex ratios in Saltmarsh Sparrows despite reasons to predict otherwise

Postdoc Jen Walsh co-authored a new paper in the Auk with collaborators from the University of New Hampshire looking at adaptive sex ratio manipulation in Saltmarsh Sparrows. The authors determined the sex of 990 offspring from 370 nests and characterized variation in site- and population-level sex ratios. They found no…

Daniel’s research featured in Nature Ecology & Evolution

Just-arrived postdoc Daniel Hooper has a paper from his dissertation newly out in Nature Ecology and Evolution entitled Chromosomal inversion differences correlate with range overlap in passerine birds. Abstract is copied below, but his ‘behind the paper’ article in the same issue is also very much worth a read. Abstract:…

Stepfanie’s paper makes the cover of PLOS Genetics!

Grad student Stepfanie Aguillon’s paper is featured on the cover of the current issue of PLOS Genetics. Here is what that journal has to say about her contribution: Florida Scrub-Jays reveal new details about isolation-by-distance. The pattern of isolation-by-distance is observed often in nature, but we rarely have means to…
