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 theExpand
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)Expand
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 twiceambient atmospheric CO2 levelsExpand
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 wasExpand
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 largeExpand
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 andExpand
Grazing management effects on plant species diversity in tallgrass prairie
Abstract A 6-year study was conducted in tallgrass prairie to assess the effects of grazing management (cattle stocking densities and grazing systems) on plant community composition and diversity.Expand
Biomass Production in a Tallgrass Prairie Ecosystem Exposed to Ambient and Elevated CO"2.
Responses to elevated CO"2 have not been measured for natural grassland ecosystems. Global carbon budgets will likely be affected by changes in biomass production and allocation in the majorExpand
Carbon dynamics and microbial activity in tallgrass prairie exposed to elevated CO2 for 8 years
Alterations in microbial mineralization and nutrient cycling may control the long-term response of ecosystems to elevated CO2. Because micro-organisms constitute a labile fraction of potentiallyExpand
