Songs, speciation, and sparrows

Postdoc Dave Toews provides some perspective in a “News and Views” article in the journal Molecular Ecology on new behavioral research in the white-throated sparrow conducgted by Sara Lipshutz (in Elizabeth Derryberry’s lab at Tulane), which compared bioacoustic variation across a contact zone between two white-throated sparrow subspecies. White-throated sparrows …

Natalie, Dave, and Scott review discoveries about the genetics of carotenoid coloration

Spurred by several exciting findings in warblers and canaries, current lab members Dave Toews and Natalie Hoffmeister, and lab alum Scott Taylor, reviewed what is known about the evolution and genetics of carotenoid processing in animals in a paper just published in Trends in Genetics. Animals cannot synthesize carotenoids and …

New paper by Jen Walsh et al on sparrow diversity

Postdoc Jen Walsh and collaborators recently published a paper in Molecular Ecology investigating the genetic structure of the Saltmarsh-Nelson’s sparrow subspecies complex. Using a reduced representation sequencing approach coupled with morphological data, this study offers the first comprehensive view into subspecies variation within Saltmarsh and Nelson’s sparrows. The authors found …

Jen Walsh et al. on the conservation genetics of sparrows

Postdoc Jen Walsh and collaborators recently published a paper in Conservation Genetics investigating the temporal stability of the Saltmarsh-Nelson’s sparrow hybrid zone. By comparing genetic, morphological, and survey data from the same sites from two time periods (1998 and 2013), this study finds that Nelson’s Sparrows are moving further south …
