The Nebraska Sand Hills exist in a semi-arid climatic environment and the land surface is grassland growing on sandy soils. These soils have been periodically active throughout the Holocene, but are currently stabilized by the vegetation. However, a shift in climate could cause grassland death and eventual sand dune remobilization. Our studies used the CENTURY nutrient cycling and ecosystem model to investigate the impacts of drought, plant functional type, fire, grazing, and erosion on… 
Seventy-Eight Years of Vegetation Dynamics in a Sandhills Grassland
Abstract The Nebraska Sandhills are a unique and valuable grassland resource within the Great Plains with a long history of grazing. In 1926, a vegetation study was established at the Nebraska
Climate Change, Drought, and Wetland Vegetation
Many climate change models forecast global increases in drought severity and duration along mid-latitudes. Areas that would typically receive ample precipitation allowing for the maintenance of
A desert in disguise: The resilience of the Nebraska Sandhills
Aboveground net primary production (ANPP) is a key ecosystem characteristic, which integrates fluxes of matter and energy, and is useful metric to compare productivity across terrestrial ecosystems.
Quantifying Grassland-to-Woodland Transitions and the Implications for Carbon and Nitrogen Dynamics in the Southwest United States
Replacement of grasslands and savannas by shrublands and woodlands has been widely reported in tropical, temperate and high-latitude rangelands worldwide (Archer 1994). These changes in vegetation
Drought susceptibility in emergent wetland angiosperms: a comparison of water deficit growth in five herbaceous perennials
This study provides experimental evidence on how herbaceous macrophytes grow under drought conditions and helps develop better working models on how wetlands will respond to changing environmental conditions that lead to decreased water supply.
From soilscapes to landscapes: A landscape‐oriented approach to simulate soil organic carbon dynamics in intensively managed landscapes
Most available biogeochemical models focus within a soil profile and cannot adequately resolve contributions of the lighter size fractions of organic rich soils for enrichment ratio (ER) estimates,
Long-term Sandhills prairie responses to precipitation, temperature, and cattle stocking rate
Warm-season grass and total basal cover responded positively to lag 3-year growing season precipitation indicating delayed responses to improved growing season conditions, but these variables also were positively associated with stocking rate, suggesting signaling factors governing basal responses in prairie remain largely unresolved.


Environmental change in grasslands: Assessment using models
Modeling studies and observed data suggest that plant production, species distribution, disturbance regimes, grassland biome boundaries and secondary production (i.e., animal productivity) could be
Observations and modeling of biomass and soil organic matter dynamics for the grassland biome worldwide
Century is a model of terrestrial biogeochemistry based on relationships between climate, human management (fire, grazing), soil properties, plant productivity, and decomposition. The grassland
Fire and Grazing in the Tallgrass Prairie: Contingent Effects on Nitrogen Budgets
Fire and grazing occur together in many of the world's grasslands, but their effects on nutrient cycling have usually been studied as if they acted separately. We hypothesized that grazing by large
Dune-dammed paleovalleys of the Nebraska Sand Hills: Intrinsic versus climatic controls on the accumulation of lake and marsh sediments
Although running water is the dominant geomorphic agent on Earth, eolian processes can gain ascendancy in regions where the climate is arid, vegetation is sparse, and abundant sand is available for
Deterioration of Grassland from Stability to Denudation with Decrease in Soil Moisture
Conditions of the central area of the mid-continental grassland reveal in general changes that have been wrought elsewhere from east to west by continued drought.
The potential response of eolian sands to greenhouse warming and precipitation reduction on the Great Plains of the U.S.A.
Abstract Sand dunes and sand sheets are extensive on the semi-arid Great Plains but are at present stabilized by a sparse vegetation cover. Use of a dune mobility index, which incorporates wind
Secondary Succession and the Pattern of Plant Dominance Along Experimental Nitrogen Gradients
The distributions along the experimental gradients of most of the common species were consistent with the pattern observed in the old—field survey, demonstrating that nitrogen influences the pattern of secondary succession at Cedar Creek.
Grassland vegetation changes and nocturnal global warming
Increased spring TMIN was correlated with decreased net primary production by the dominant C4 grass and with increased abundance and production by exotic and native C3 forbs, which may make this ecosystem more vulnerable to invasion by exotic species and less tolerant of drought and grazing.
Large-scale stabilized dunes on the High Plains of Colorado: Understanding the landscape response to Holocene climates with the aid of images from space
Principal-component analysis of Landsat Thematic Mapper images from eastern Colorado reveals stabilized dune fields that are composed of single and compound parabolic dunes, some longer than 10 km.
