Webb1 dec. 2006 · Classical ecological theory suggests that these two species could not coexist in the same environment. However, a closer look at the theory that leads to that conclusion ( Levins 1979, Armstrong and McGehee 1980) reveals that something more complicated may happen. Under certain circumstances, species can indeed occupy the same niche.

Haplotype diversity of P. major was identified in 12 of the 21 locations. For the other nine locations, only one haplotype was found.
