A 2006 analysis of salamanders of the genus Eurycea, in the Appalachians, found that the current taxonomy of the group greatly underestimated species level diversity.The authors found that patterns of phyleographic diversity were more associated with historical (rather than modern) drainage connections, indicating that major shifts in the drainage patterns of the region played an important ...
Axolotls may be confused with the larval stage of the closely related tiger salamander (A. tigrinum), which are widespread in much of North America and occasionally become paedomorphic, or with mudpuppies (Necturus spp.), fully aquatic salamanders from a different family that are not closely related to the axolotl but bear a superficial ...
