The publication of The Colorado Plateau: Cultural, Biological, and Physical Research in 2004 marked a timely summation of current research in the Four Corners states. This new volume, derived from the seventh Biennial Conference on the Colorado Plateau in 2003, complements the previous book by focusing on the integration of science into resource management issues. The 32 chapters range in content from measuring human impacts on cultural resources, through grazing and the wildland-urban interface issues, to parameters of climate change on the Plateau. The book also introduces economic perspectives by considering shifting patterns and regional disparities in the Colorado Plateau economy. A series of chapters on mountain lions explores the human-wildland interface. These chapters deal with the entire spectrum of challenges associated with managing this large mammal species in Arizona and on the Colorado Plateau, conveying a wealth of timely information of interest to wildlife managers and enthusiasts. Another provocative set of chapters on biophysical resources explores the management of forest restoration, from the micro scale all the way up to large-scale GIS analyses of ponderosa pine ecosystems on the Colorado Plateau. Given recent concerns for forest health in the wake of fires, severe drought, and bark-beetle infestation, these chapters will prove enlightening for forest service, park service, and land management professionals at both the federal and state level, as well as general readers interested in how forest management practices will ultimately affect their recreation activities. With broad coverage that touches on topics as diverse as movement patterns of rattlesnakes, calculating watersheds, and rescuing looted rockshelters, this volume stands as a compendium of cutting-edge research on the Colorado Plateau that offers a wealth of insights for many scholars.

Reptilian scales may seem simple to the naked eye, but under a microscope they are very complex with multiple patterns across their surface that are much like a human fingerprint. These patterns have been shown to be species specific but there has been no way to quantify these differences. A new technique has been found using the confocal microscope that allows a measurement of the roughness of a surface. The roughness of the scales of Crotalus atrox were measured and compared with factors such as sex, age, clade, and various environmental variables to help determine if this technique may be useful to taxonomists in determining species, or if it is simply a measure that is dependent on the environment. Crotalus atrox was chosen for this study because it is a very widespread species spanning across the southwestern United States and encompassing many different biomes. The results found that the roughness of a scale decreased as the snake aged, and was significantly different between the two clades, with the Eastern clade being much rougher. When these factors were controlled in the analysis of the environmental factors, it was found that a higher temperature seasonality and a higher maximum temperature in the warmest month both caused an increase in scale roughness.
