The low number of [F.sub.1] hybrids seen in the wild suggests that these weta are forming a bimodal
hybrid zone (Mckean et al.

hybrid zone. Molecular Ecology 3: 531-539.
Thus, further research on contact zones is needed to clarify which population and landscape attributes (either natural or antropogenically produced) are likely to affect the process of natural hybridization and, consequently, the persistence of
hybrid zones.

Many avian
hybrid zones have demonstrated intrinsic selection against hybrids (Stetre et al., 1999; Bronson et al., 2003; Haavie et al., 2004), extrinsic selection for hybrids (Flockhart and Wiebe, 2008), or a combination of both (Good et al, 2000; Gay et al, 2008); yet, few of these studies have examined more than one
hybrid zone within the same species complex.

hybrid zone occurs along a transition between 2 marine ecosystems, the first characterized by fjords and estuaries and the second by the California Current and coastal upwelling (Bell 1996).
Each occupies a unique geographical distribution except for the state of Tabasco in southeastern Mexico, where they coexist and interbreed in what's known as a
hybrid zone.

hybrid zone between the two species.
