Germination thresholds of the Mixed-grass Prairie species as affected by global climate change: A FACE study.
… CO2 alone decreased germination by about 14% in Bouteloua gracilis. Heating tended to enhance Tb and to reduce θ50 in Bouteloua gracilis, which may slow the initiation of germination but seeds germinate faster in spring. Elevated CO2 concentrations tended to increase but CT tended to decrease Tb …

Diet and Nutrition of the Pronghorn Antelope
… gold aster (Chrysopsis villosa), and blue grama (Bouteloua gracilis). Cultivated small grain crops were not a major food source of pronghorn. Differences in diet composition, plant groups, plant groups and time of use and plant group, area, month interaction were significant. Average in vitro …

Digestibility of Common Forage Plants and Energetic Requirements of the Black-Tailed Prairie Dog
… grama mixture (Buchloe dactyloides/Bouteloua gracilis) they were fed. They would have to consume 0.229 kcal · g-1 · day-1 of this forage to assimilate 0.072 kcal · g-1 · day-1 and maintain their weight. The proximate composition of forages fed in feeding trials was similar to that …

Geochemical Investigations of Mineral Weathering: Quantifying Weathering Intensity, Silicate versus Carbonate Contributions, and Soil-Plant Interactions
… paradoxa, Rhus trilobata), and an annual grass (Bouteloua gracilis) and a lichen (Xanthoparmelia lineola). We found that plant 87Sr/86Sr ratios covaried with variations in plant physiognomy, life history, and rooting depth. In addition, the proportion of atmospheric dust and bedrock mineral …

Key To Microscopic Fragments of Plant Tissue in Prairie Dog Stomachs and Food Habits of Prairie Dogs in South Dakota
… threadleaf sedge (Carex filifolia), blue grama (Bouteloua gracilis), and western wheatgrass (Agropyron smithii). Seasonal differences for spring and summer were not significant (P>0.05). Insect matter and seed material were not important (less than 5 percent). Winter food habits showed an …

Soil geomorphology of the eastern Sevilleta Long Term Ecological Research Site
… the distributions of Larrea tridentata, Bouteloua gracilis, and Bouteloua eriopoda. However, distributions of these species were not affected by lithology, soil age, soil salinity, or high soil pH.</p>

Quantifying and Simulating Fine-Scale Spatial Patterns in Plant Populations
… changes in spatial pattern occur in <em>Bouteloua gracilis</em> populations at multiple, sub-meter scales, reinforcing the belief that local interactions are important factors in community structure (Chapter 1). It further illustrates that the very notion of 'local' is markedly influenced …

Effects of Fire on the Nutritional Ecology of Selected Ungulates in the Southern Black Hills, South Dakota
… was greater in 2002 than 2003. Consumption of Bouteloua gracilis by white-tailed deer was greater in winter than summer, 2003 than 2002, and burned than unburned habitat; total forb was greater in summer than winter and burned than unburned habitat; and Symphoricarpus occidentalis, total shrub, …

Soil Moisture Measurements and Modeling at a Geomorphically Reclaimed Coal Mine in New Mexico
… of existing plant blue grama grass (Bouteloua gracilis) and cheatgrass was also predicted by comparing soil water potential at different depths with the wilting points of the respective plants. The results show that establishment of vegetation in geomorphically reclaimed soil is …

Factors Influencing a Declining Pronghorn Population in Wind Cave National Park, South Dakota
… collected from pronghorn in 2002. Blue grama (Bouteloua gracilis), common juniper (Juniperus communis), and northern bedstraw (Galium boreale) were identified as important seasonal food items, representing 14.6, 10.6, and 6.5% of the annual diet, respectively. Annual diets of pronghorn in WCNP …
