Prior to this study, no information existed concerning how arthropods, bats, and other vertebrates use caves in northwestern-most Arizona. Baseline investigations were conducted at seven of the largest known caves on Grand Canyon-Parashant National Monument for arthropods, bats, and other vertebrates.  During this one-year study (summer 2005 through winter 2006), we identified 52 morphospecies including 44 arthropods, four bats, and four other vertebrate morphospecies.  Of the cave-dwelling arthropods, we found 10 entrance dwellers, four troglophiles, eight questionable troglophiles, nine trogloxenes, eight accidentals, three taxa of unknown cave affiliations, and two mammalian ectoparasites. We made several contributions to the entomological record including two new genera, seven new species, three possible new species, one range expansion and one possible range expansion.  Also, we identified five bat roosts - one hibernaculum, two night roosts, and three summer roosts of unconfirmed use.  Observed arthropod richness per cave ranged from one to 14 morphospecies and observed bat and other vertebrates (combined) richness was between one and three morphospecies.  We did not detect any cave-adapted arthropods during this investigation.  This project was funded through the National Park Service.
