Wide prevalence of hybridization in two sympatric grasshopper species may be shaped by their relative abundances

Table 3 Number of hybrids detected in each population using STRUCTURE, NewHybrids and Adegenet (conservative estimate: hybrids detected by all three programs, relaxed estimate: hybrids detected by two programs), hybridization rate (in %) and sample sizes for each population and species (pre-identified by morphology)

Pop	Sample size	Sample size	No. of hybrids conservative	No. of hybrids relaxed	Hybridization rate conservative (%)	Hybridization rate relaxed (%)
Pop	Ch. montanus	Ch. parallelus	No. of hybrids conservative	No. of hybrids relaxed	Hybridization rate conservative (%)	Hybridization rate relaxed (%)
