The Chihuahuan Desert is considered one of the most diverse deserts in the world and its aquatic systems have been identified as unique and of global importance. Despite this, the Chihuahuan Desert has remained relatively unstudied, especially concerning its aquatic systems and how the extreme desert environment has shaped the diversity of the organisms within them. In this study we examined the effects of isolation and disturbance on macroinvertebrate diversity in both temporary and permanent desert ponds. To examine the effects of isolation and desiccation, macroinvertebrates were collected from a permanent spring (Squaw Spring) and six nearby temporary ponds (tanks) …
