Assignment Problem: The Blue Ridge Two-Lined Salamander lives in rocky, montane streams in the Appalachian Mountains, and the Southern Two-Lined Salamanders lives in slower, flatter streams in the Piedmont. However, these two species coexist where these two ecoregions meet in the Appalachian foothills. The competitive exclusion principle predicts that two species cannot coexist if they occupy exactly the same ecological niche, raising the question of how these very similar salamanders can live in the same stream.
You might imagine that there must be something different about the ecology of these two salamanders in order from them to coexist. Perhaps they occupy slightly different regions of the stream? To test this hypothesis, Dr. Pierson captured larval salamanders from streams in the Appalachian foothills. He used genetic data to determine the species identity of each salamander and noted whether he collected it in a riffle, run, or pool habitat within the stream. Use these data to test whether Blue Ridge Two-Lined Salamanders and Southern Two-Lined Salamanders live in different habitats where they coexist, and interpret your results based on what you've learned about the biology of these salamanders.
