I believe quetzal and aguacatillo are the key species in the cloud forests in Cerro de la Muerte because they are biologically and culturally valuable. This value contributes to ecotourism, which eventually becomes of economic benefit to local people. In this paper, I examine how the cloud forest conservation and...
Desert, desert-steppe (Gobi) zone is the largest province by area (165,000 square kilometres) of Mongolia. The Gobi contains some 560 plant species, in 80 different vegetation associations (Swift, 1991). There are number of results of nutritive value of desert-steppe’s pasture grass. Mongolia’s dry climate means that pasture grasses have less...

The objective of this study was to evaluate changes in the quantity, quality, and moisture of available forage in a riparian pasture, and shrub utilization by cattle during a 30-d late summer grazing period. A riparian pasture (44.7 ha) in northeast of Oregon was grazed with 30 yearlings (419 kg,...
Mule deer (Odocoileus hemionus), elk (Cervus elaphus), and cattle share rangelands throughout much of interior western North America. Considerable debate exists about the degree to which facilitation or competition occurs for forage between these three species (Nelson 1982, Wisdom and Thomas 1996, Miller 2002). Prior cattle grazing can have beneficial...
We assessed a photographic technique to estimate shrub yield and utilization of common snowberry, snowbrush, and heart-leafed willow found in mixed-conifer rangelands. We determined the correlation between green leaf area size (LA) and forage yield (Y) and compared plant utilization estimated by photographic technique (ULA) to actual utilization (UY) values....

White muscle disease (WMD), a degenerative muscle disease brought on by a deficiency of the essential trace nutrient selenium, is thought to be mediated by the protein Selenoprotein W (SeW). In its relationship with WMD, SeW, like many selenoproteins, binds to glutathione, serving some purpose in redox mechanisms...
The estimation of standing crop is important in the management of rangeland resources. Direct measurements by clipping, drying, and weighing of herbaceous vegetation are time-consuming and labor-intensive. Therefore, non-destructive methods for efficiently and accurately estimating standing crop are needed in rangeland forage management. We assessed a visual obstruction (VO) technique...
Management and conservation of rangelands are increasingly concerned with maintaining productivity, species composition, and diversity of native plant communities. We estimated aboveground annual productivity, species composition, and diversity of a native bunchgrass type community across 1152, 0.5 m2 plots at The Nature Conservancy’s Zumwalt Prairie Preserve in northeastern Oregon. Standing...
