Amplified Fragment Length Polymorphism (AFLP)

Abstract

"Two species and one subspecies of salamander in the genus Eurycea, two species of Plethodon and one species of Typhlotriton (recently considered to be Eurycea) salamander currently reside in an area of Onondaga Cave known as the Missouri Caverns section. Due to the presence of two known interbreeding subspecies of salamanders, Eurycea Longicauda (Long-tailed salamander) and Eurycea longicauda melanopleura (Dark-sided salamander), the possibility may exist for interbreeding of one or all of these taxa. Specifically, it is hypothesized that the two species of Eurycea longicauda may interbreed with Eurycea lucifuga (Cave salamander). through visual assessment and phenotypic analysis, all known species were identified. Tissue samples were used to identify any undiagnosed specimens through DNA fingerprinting, also known as Amplified Fragment Length Polymorphism (AFLP), a method measuring genotypic differences. This information was used to support evidence of hybridization among the co-existing species. Evidence of hybridization may indicate that the removal of human disturbance in this area may have had a prominent impact on multiple salamander species and their willingness to compete for food and other precious resources"--Abstract, page iii.
