Abstract:
... Multiple plant stresses can affect the health, esthetic condition, and timber harvest value of conifer forests. To monitor spatial and temporal dynamic forest stress conditions, timely, accurate, and cost-effective information is needed that could be provided by remote sensing. Recently, satellite imagery has become available via the RapidEye satellite constellation to provide spectral information ...

Abstract:
... Chile is one of the most important crops in New Mexico, contributing both to the agricultural economy and cultural identity of the state. Diseases are a major constraint on chile production in New Mexico and across the Desert Southwest. Chile producers in New Mexico recently reported a disorder of unknown etiology that was observed in increasing frequency for the past four years. Affected plants h ...

Abstract:
... The economic benefits of organic agriculture and its wide adoption are well documented, but the impact of that practice on soil C dynamics in irrigated croplands of semi‐arid regions is less well understood. In manure‐based organic production systems, land applications of animal wastes not only provide nutrients but could also contribute to soil carbon sequestration. A study was conducted in irrig ...

Abstract:
... The Brown-headed Cowbird (Molothrus ater (Boddaert, 1783)) is a generalist brood parasite that often lays into nests that contain conspecific eggs. Although it has often been assumed that this multiple parasitism reduces Cowbird survival, this has rarely been evaluated. We measured Cowbird survival in nests of the Blue-gray Gnatcatcher (Polioptila caerulea (L., 1766)), Plumbeous Vireo (Vireo plumb ...

Abstract:
... From September to November 2000, United States Fish and Wildlife Service biologists investigated incidents involving 221 bird deaths at 3 mine sites located in New Mexico and Arizona. These bird deaths primarily involved passerine and waterfowl species and were assumed to be linked to consumption of acid metalliferous water (AMW). Because all of the carcasses were found in or near pregnant leach s ...

Through a recent (2003–2007) survey of ectoparasites on hoofed mammals in western North America, a literature review, and examination of archived museum specimens, we found that the exotic deer-chewing louse, Bovicola tibialis (Piaget), is a long-term, widespread resident in the region. The earliest known collection was from Salt Spring Island, Canada, in 1941. We found these lice on the typical h ...

Abstract:
... We investigated amounts and particle size distributions (PSDs) of aeolian sediments collected at five heights in five ecosystem types at the Jornada Basin, Chihuahuan Desert, New Mexico, USA. Particle size distributions, mass fluxes, and percent of dust-sized (⩽50μm) mass flux were determined for all heights and all ecosystem types. Differences between sites were determined using ANOVA followed by ...

Abstract:
... Purpose: Health care providers face challenges in rural service delivery due to the unique circumstances of rural living. The intersection of rural living and health care challenges can create barriers to care that providers may not be trained to navigate, resulting in burnout and high turnover. Through the exploration of experienced rural providers' knowledge and lessons learned, this study sough ...
