To detect signs of impaired growth (hybrid inviability) the hind tibia length of both dead and living adult hybrids was measured with electronic calipers and compared via ANOVA to wild adult females of both parent species measured in a previous study (15 H.
In the Mimulus guttatus complex, there is evidence for inviability in hybrids between metal-tolerant and intolerant parents (Gardner & MacNair, 2000), although such post-zygotic isolation is not a factor between coastal and inland ecotypes of the same taxon (Lowry et al., 2008).
