This study utilizes a multidisciplinary research approach integrating the sciences of archaeology, geology, pedology and paleoclimatology. Deeply stratified and radiocarbon dated sedimentary sequences spanning the last 10,000 yr B.P. are reported for the Cremer site (24SW264), south-central Montana. Previous investigations at the site revealed an archaeological assemblage with Early Plains...

Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...
The hazards-of-place model of vulnerability to environmental hazards posits that vulnerability has biophysical and social components. While biophysical characteristics are important in predicting locations of elevated wildfire risk, the social characteristics of human communities may help us predict locations of elevated wildfire impacts. We examine the relationship between biophysical and...
A great deal of research has documented racial disparities in imprisonment rates in the United States, but little work has been done to understand the process by which inmates are assigned to individual correctional facilities. This article extends research on racial disparities in imprisonment rates to consider racial disparities in...
This study examines the structure of the energy industry and the energy policy-planning network (EPPN). I use cross-sectional director interlocks from 2002 to examine the social networks amongst a sample of the largest energy firms, between these firms and the EPPN, and to calculate relative network centrality measures for the...
Studies that have examined watershed groups have lacked the analysis of an empirical national data set to account for the factors that affect watershed groups growth and variation. This has made it difficult to assume any particular relationship between the presence of watershed groups and any environmental, social or political...

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease where paralysis of the body is the result of motor neuron function loss. A potential cause of ALS is the loss of zinc from Superoxide Dismutase (SOD). SOD’s cellular responsibility is to enzymatically react with the superoxide anion forming oxygen and the...

West Nile Virus (WNV), a vector-borne disease continues to be a serious threat to public health in the United States, particularly in the Southwest region. While all the states in the U.S. experienced a decreasing trend of WNV disease in 2010, the state of Arizona experienced a sharp increase from...
