Data from: Structure of a mosaic hybrid zone between the field crickets Gryllus firmus and G. pennsylvanicus

Erica L. Larson, C. Guilherme Becker, Eliana R. Bondra & Richard G. Harrison
Hybrid zones provide insight into the nature of species boundaries and the evolution of barriers to gene exchange. Characterizing multiple regions within hybrid zones is essential for understanding both their history and current dynamics. Here, we describe a previously uncharacterized region of a well-studied hybrid zone between two species of field crickets, Gryllus pennsylvanicus and G. firmus. We use a combination of mitochondrial DNA sequencing, morphological data, and modeling of environmental variables to identify the...
