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.
in central California (Saarman & Pogson 2015).
musculus meet in a well-studied hybrid zone
ranging across Denmark, the Netherlands, Germany, Czech Republic and Bulgaria (Jones et al., 2010; Wang et al., 2011), and M.
richteri, and their application to the study of a hybrid zone

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.
glaucescens-occidentalis 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

galloprovincialis) in the central coast of Chile (Toro et al., 2005; Carcamo et al., 2005; Tarifeno et al., 2005, Aldea & Valdovinos, 2005; Borsa et al., 2007; Ruiz et al., 2008) could represent a potential hybrid zone
between the two species.
