Chemical pollutants and/or climate change have the potential to break down reproductive
barriers between species and facilitate hybridization. Hybrid zones may arise in response to …

Hybridization, defined as the crossing between individuals from different populations, is a
common phenomenon in fishes. Moreover, many fish hybrids have been developed to be …

Hybridization is a complicated, oft-misunderstood process. Once deemed unnatural and
uncommon, hybridization is now recognized as ubiquitous among species. But hybridization …

Hybridization and introgression are very common among freshwater fishes due to the
dynamic nature of hydrological landscapes. Cyclic patterns of allopatry and secondary …

The tips in the tree of life serve as foci for conservation and management, yet clear
delimitations are masked by inherent variance at the species–population interface. Analyses …

Abstract The Speckled Dace, Rhinichthys osculus (Girard), is a small species of fish
