We used 10 years of remote camera photo data from a 100 Km Sq, permanent grid in southcentral New Mexico to assess the relative contributions of top-down and bottom-up forces structuring the mesocarnivore community. Specifically, we used quantile regression to determine the relative influences of puma (Puma concolor) and black bear (Ursus americanus) - top-down factors - and jackrabbit (Lepus californicus) and desert cottontain (Sylvilagus auduboni) - bottom-up factors - on the diversity of the mesocarnivore community across 25 camera sites. The mesocarnivore community on our study site consisted of coyote (Canis latrans), bobcat (Lynx rufus), gray fox (Urocyon cinereoargenteus), ring-tailed cat (Bass","pubDate":"2026-10-28T16:23:17Z","url":"https://doi.org/10.5281/zenodo.23736673"},"indexado":"2026-10-30T00:56:37.108Z"}}
