Is historical hybrid zone movement underappreciated?

38 JBI
Two crested newt studies, previously highlighted here and here, support historical hybrid zone movement – movement on the scale of hundreds of kilometers and spanning multiple millennia. Before these crested newt examples, little to no empirical evidence for historical hybrid zone movement was available. Does this mean that crested newt hybrid zones are particularly dynamic? Or has the prevalence of historical hybrid zone movement in other systems simply been overlooked? In a perspective piece in Journal of Biogeography I argue the latter: historical hybrid zone movement is likely to be more common than currently appreciated.

Reference: Wielstra, B. (2019). Historical hybrid zone movement: more pervasive than appreciated? Journal of Biogeography TBA.

About Ben Wielstra

I am a biologist interested in the interaction among closely species, both ecologically and genetically, during the course of their evolution. In my studies I'm employing the newt genus Triturus.
