Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...
Molecular dynamics (MD) simulations are used to study, in detail, the transfer of thermal (vibrational) energy between objects with discrete vibrational spectra to those with a semi-continuum of spectra. The transfer of energy is stochastic and strongly dependent on the instantaneous separation between the bodies. The insight from the MD...
Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures
that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how
silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...
Climate change and efforts to address it have put the electric utility system under increasing pressure to adapt and evolve. Key to the success of these efforts will be the support of public utility commissions, the state agencies that oversee retail electric utilities. In an effort to determine how these...

Infestation by onion thrips, Thrips tabaci Lindeman, was determined on transplants of onion (Allium cepa L.) received in Colorado during March and April from out-of-state sources (Imperial Valley, CA; near Phoenix, AZ; and southern Texas) during 2004 to 2008. In the 5 years of the study, 50 to 100% of...
Unconditioned responding (UCR) to a naturally aversive stimulus is associated with defensive responding to a conditioned threat cue (CS+) and a conditioned safety cue (CS-) in trauma-exposed individuals during fear acquisition. However, the relationships of UCR with defensive responding during extinction training, posttraumatic stress disorder (PTSD) symptom severity, and fearful...
Most administrators and ecologists agree that reducing the levels of hazardous fuels on forests is essential to restore healthy
watersheds and protect adjacent human communities. The current debate over the appropriateness, technique, and timing of treatments
utilized to restore vegetation structure and composition is currently on-going at local, state, and...
The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal...
Forest-fire policy of U.S. federal agencies has evolved from the use of small
patrols in newly created National Parks to diverse policy initiatives and institutional arrangements
that affect millions of hectares of forests. Even with large expenditures and
substantial infrastructure dedicated to fire suppression, the annual area burned by wildfire...
