Salamanders, never the swiftest nor the most wide ranging of vertebrates, are given to the formation of isolated populations. Salamander systematics has recent taken to treating these isolated populations as separate species based primarily on differences in mitochondrial or nuclear DNA, but without actual demonstrations of reproductive (versus geographical) isolation. Therefore the species level systematics of the salamanders is in some disarray with a rapidly increasing number of recognized "species". The combination of the three websites on the left should alleviate some of these problems. The first two sites between them cover most of the North American species. The CNAH website contains the most up-to-date list of the currently recognized species as well as photographs of many of the species. Clicking on any of these three website will open that site in a separate browser window. To leave any of these web sites orNearctica, simply close the respective window. |
