Data from: Differential introgression in a mosaic hybrid zone reveals candidate barrier genes

Erica L. Larson, Jose A. Andres, Steven M. Bogdanowicz & Richard G. Harrison
Hybrid zones act as genomic sieves; although globally advantageous alleles will spread throughout the zone and neutral alleles can be freely exchanged between species, introgression will be restricted for genes that contribute to reproductive barriers or local adaptation. Seminal fluid proteins (SFPs) are known to contribute to reproductive barriers in insects and have been proposed as candidate barrier genes in the hybridizing field crickets G. pennsylvanicus and G. firmus. Here, we have used 125 SNPs...

Data from: Hybridization and adaptation to introduced balloon vines in an Australian soapberry bug

Contemporary adaptation of plant feeding insects to introduced hosts provides clear cases of ecologically based population divergence. In most cases the mechanisms permitting rapid differentiation are not well known. Here we study morphological and genetic variation associated with recent shifts by the Australian soapberry bug Leptocoris tagalicus onto two naturalized Neotropical balloon vines, Cardiospermum halicacabum and C. grandiflorum that differ in time since introduction. Our results show that these vines have much larger fruits than...
