Given the importance of Big Bend National Park for biodiversity and habitat protection in the Trans-Pecos ecoregion, the distribution of species in the park has been well-studied. However, it is also important to monitor changes in the distribution of species over time and to gauge what factors within the park ... Read More

Desert bighorn sheep and mule deer have experienced widespread declines in distribution and abundance in the Texas Trans-Pecos. While translocation efforts have been successful in reviving these species, the ongoing expansion of aoudad populations across the region have raised concern for native species survival. Similarities in physiology and native range ... Read More

As desert bighorn sheep restoration continues in Texas, desert bighorn sheep are now potentially threatened by aoudad distribution and population increase. This study evaluated the use of artificial water sources, documenting seasonal and temporal usage by aoudad and desert bighorn in a coexisting area.

The black-tailed prairie dog (Cynomys ludovicianus) plays an important role in maintaining ecological integrity in western grasslands. A 2010 Texas Parks and Wildlife Department inventory of prairie dog populations revealed that their range has decreased in the southern and western boundaries of their historical range within the Trans-Pecos region.

Populations of quails in Texas have declined over the past few decades due primarily to habitat loss. However, the role that parasites may play in such declines has been largely dismissed. To help address this, we collected scaled quail (Callipepla squamata), Gambel’s quail (Callipepla gambellii), and Montezuma quail (Cyrtonyx montezumae) ... Read More

The Trans-Pecos region of Texas has four species of quail: the scaled quail, Gambel’s quail, Montezuma (Mearns) quail, and northern bobwhite. Currently, little research regarding parasites has been conducted in the Trans-Pecos; however, it is thought that parasites could be influencing range, health, reproduction, and survival of scaled quail, Gambel’s ...
