Long- and short-term effects of fire on nitrogen cycling in tallgrass prairie
Fires in the tallgrass prairie are frequent and significantly alter nutrient cycling processes. We evaluated the short-term changes in plant production and microbial activity due to fire and the
Responses of Soil Respiration to Clipping and Grazing in a Tallgrass Prairie
Soil-surface CO 2 flux (F,) is an important component in prairie C budgets. Although grazing is common in grasslands, its effects on F s have not been well documented. Three clipping treatments: (i)
Biomass production and species composition change in a tallgrass prairie ecosystem after long‐term exposure to elevated atmospheric CO2
To determine the long‐term impact of elevated CO2 on primary production of native tallgrass prairie, we compared the responses of tallgrass prairie at ambient and twice‐ambient atmospheric CO2 levels
Biomass Production in a Tallgrass Prairie Ecosystem Exposed to Ambient and Elevated CO"2.
In natural ecosystems with periodic moisture stress, increased water-use efficiency under elevated CO"2 apparently would have a greater impact on productivity irrespective of photosynthetic pathway.
Fluxes of CO2 From Grazed and Ungrazed Tallgrass Prairie
Abstract To determine the impact of seasonal steer grazing on annual CO2 fluxes of annually burned native tallgrass prairie, we used relaxed eddy accumulation on adjacent pastures of grazed and
Intensive-Early Stocking and Season-Long Stocking of Kansas Flint Hills Range
Highlight: Native Flint Hills bluestem range was stocked at twice the normal rate, 1.7 acres per steer. Daily steer gain and gain per acre were greater for IES. Late summer gain by steers on SLS was
Grazing management effects on plant species diversity in tallgrass prairie
It is suggested that large grazer densities, fire, and annual climatic variability interact to influence patterns of plant community composition and diversity in tallgrass prairie.
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
Evapotranspiration in a Prairie Ecosystem: Effects of Grazing by Cattle
Grazing by ungulates is common in grasslands and may influence evapotranspiration (ET). The Bowen ratio energy balance method (BREB) was used to measure ET from grazed (GR) and ungrazed (UGR)
