Species recognition of four species of salamanders, Ambystoma, tigrinum, A. maculatum, A. opacum, and A. tremblavi, was studied in a series of investigations performed from September 9, 1984 to October 29, 1984. The purpose of the study was to determine if vision is a component in interspecies recognition in these salamanders and, if so, to determine what specific sign stimuli are effective.A total of 23 individual salamanders were tested in three experimental situations involving choices between live conspecific and heterospecific salamanders, live conspecifics and heterospecifics where no olfactory cues were available, and between different models, varying either in pattern composition or ground color.In the preliminary tests, all four species of salamander preferred their conspecifics. In the live animal tests only the tiger salamanders preferred their conspecifics. In the model tests only the tiger salamanders showed a preference for one of the models, preferring the supernormal to the natural model.

Thesis (M.A.)--University of Missouri-Columbia, 2008. / Vita. "Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg deposition or larval development. I have collected data on both larval and adult salamanders in headwater streams in western North Carolina to determine the impacts of even-aged timber harvest on salamander populations and to assess the efficacy of riparian buffers in ameliorating these effects. My data show that larval two-lined salamanders are negatively impacted by increased stream sedimentation following riparian logging and that increasing the riparian buffer around the stream reduces sedimentation effects; larval black-bellied salamanders were not significantly affected by riparian alteration. Adult and juvenile salamanders dependent on terrestrial habitat were also affected; seal salamander densities were significantly higher in streams with little to no riparian buffer while Ocoee salamanders were significantly less abundant. It is unlikely that salamanders will persist or thrive for more than a season or two in logged forests due to a significant deterioration in body condition of Ocoee salamanders in logged riparian areas. My results indicate that current riparian forest conservation measures are inadequate to preserve either larval or adult salamander populations." -- leaves xi-xii.
