Plague seroprevalence was estimated in populations of pumas and bobcats in the western United States. High levels of exposure in plague-endemic regions indicate the need to consider the ecology and pathobiology of plague in nondomestic felid hosts to better understand the role of these species in disease persistence and transmission.

Curly top in sugar beet continues to be a challenging disease to control in the western United States. To aid in development of host resistance and management options, the curtovirus species composition was investigated by sampling 246 commercial fields along with nursery and field trials in the western United States. DNA was isolated from leaf samples and the species were identified using spec...

MAY 2003 AMERICAN METEOROLOGICAL SOCIETY | T he number and extent of wildfires in the western United States each season are driven by natural factors such as fuel availability, temperature, precipitation, wind, humidity, and the location of lightning strikes, as well as anthropogenic factors. It is well known that climate fluctuations significantly affect these natural factors, and thus the sev...

INTRODUCTION Ownership of the public domain has long been a contentious issue between Western U.S. states and the federal government. The recent armed confrontations at Nevada’s Bundy Ranch and Oregon’s Malheur Wildlife Refuge are simply one manifestation of western frustration. Within the last five years the legislatures of seven Mountain West states (Arizona, Colorado, Idaho, Montana, Nevada,...

reports the federal government’s newest estimate of Oregon’s household food insecurity rate. Oregon’s unexpected ranking as one of the “hungriest” states in the late 1990s embarrassed state political leaders and mystified researchers. Its subsequent improvement in the early 2000s was the source of some pride among advocates and social service agency leaders. Its recent increase during the curre...

The western United States is known for its water shortages due to large seasonal and inter-annual variability of precipitation as well as increasing demand. Climate change will impact the availability of water in the western United States through the modification of precipitation characteristics. Satellite data presents the opportunity to study these changes at a fine, continuous spatial resolu...

ABSTRACT Armillaria mellea infects hundreds of plant species in natural and managed ecosystems throughout the Northern hemisphere. Previously reported nuclear genetic divergence between eastern and western U.S. isolates is consistent with the disjunct range of A. mellea in North America, which is restricted mainly to both coasts of the United States. We investigated patterns of population struc...

The present study sought to investigate the extent to which Persian idiomatic expressions would influence the western translators' strategies in providing the ultimate product in English, and it also attempted to uncover the underlying assumptions in target text, then to suggest some weighty strategies to overcome difficulties with translation. For this purpose, the data was analyzed within the...

BACKGROUND The western tarnished plant bug Lygus hesperus is an economically important pest that belongs to a complex of morphologically similar species that makes identification problematic. The present study provides evidence for the use of DNA barcodes from populations of L. hesperus from the western United States of America for accurate identification. METHODOLOGY/PRINCIPAL FINDINGS This ...
