Pastoral livestock production is considered a pillar of the Mongolian economy. Since the early 1990's, Mongolia has transitioned to a market economy, and livestock numbers have trended upward. Recent remote sensing studies have indicated widespread overgrazing; however, to date, no studies have examined grazing pressure on a national scale to assess the(More)
Two cross-sectional studies were conducted at a German aluminum (Al) powder plant to evaluate possible nervous system effects from occupational Al exposure. The investigation included biological monitoring, a neuropsychological test battery, and event-related P300 potentials. Neurophysiologic findings in workers chronically exposed to Al dust did not differ(More)
Mongolia has one of the strongest climate warming signals on Earth, and over 40% of the human population depends directly or indirectly on pastoral livestock production for their livelihoods. Thus, climate-driven changes in rangeland production will likely have a major effect on pastoral livelihoods. We examined patterns of climate change and rangeland(More)
In North America, it has been shown that cattle in warmer, drier grasslands have lower quality diets than those cattle grazing cooler, wetter grasslands, which suggests warming will increase nutritional stress and reduce weight gain. Yet, little is known about how the plant species that comprise cattle diets change across these gradients and whether these(More)
Woody plant encroachment—the conversion of grasslands to woodlands—is among the greatest challenges faced by rangelands worldwide. Yet this phenomenon is poorly understood, and complex land use dynamics make interpreting the timing and extent of land cover changes a global challenge. For many regions, the true degree and rate of historical change in woody(More)
After the transition of Mongolia's agriculture sector to a market economy in the early 1990's, community-based rangeland management (CBRM) organizations have been established across Mongolia to cooperatively manage rangeland resources. We hypothesized that rangeland ecoregions under CBRM would have greater biomass than ecoregions managed using traditional(More)

Since the 1990's, herding communities across Mongolia have established over 2000 community-based rangeland management (CBRM) organizations to improve livestock grazing management and reverse perceived declines in rangeland (grassland) productivity. Here, we compare the vegetation and soils of rangelands managed by these formal community-based herder groups(More)
