Ecological niche models (ENMs) are crucial tools for anticipating range shifts driven by climate change. As hypotheses of future biotic change, they can be difficult to test using independent data. The fossil record is the best way to assess the ability of ENMs to correctly predict range shifts because it provides empirical ranges under novel climate conditions. We tested the performance of ENMs using...
The late Pleistocene asphalt seeps of Rancho La Brea are well-known for their impressive assemblage of carnivorans, which make up the vast majority of the preserved fauna. Of particular interest is the large number of dire wolf and sabertooth cat specimens. Carcass domination, the hypothesis that predators engaged in intense competition for trapped prey, may explain the mechanism of this predator...
