Tallgrass Prairie: Remnants and Relicts
The tallgrass prairie once was continuous throughout the eastern Great Plains. Now, scattered remnants remain. The distribution of some of the most interesting and socially valuable remnants occur along the base of the Rocky Mountains as relicts from a past era. When the species composition of these Colorado grasslands is compared with that of the eastern tallgrass prairie by an index of simila...
متن کاملPartitioning of Nitrogen over Five Growing Seasons in Tallgrass Prairie
Annual spring burning of tallgrass prairie increases plant biomass production despite losses of N and lower net N mineralization. To better understand how burning influences the cycling of N in prairie, '5N was injected to soil as NH4+, and the partitioning between plant and soil N pools was followed over five growing seasons in annually burned and unburned prairie. Applied '5N was rapidly immo...
متن کاملLekking and Nesting Response of the Greater Prairie-chicken to Burning of Tallgrass Prairie
In the southern Great Plains, the greater prairie-chicken (Tympanuchus cupido) is confined to tallgrass prairie, a habitat now largely converted to agriculture. Remaining prairie is highly fragmented and subjected to land management practices that greatly alter the ecosystem of this species. Chief among these practices are deliberate, large-scale spring burns associated with early intensive sto...
متن کاملCarbon quality and the temperature sensitivity of soil organic carbon decomposition in a tallgrass prairie
The temperature sensitivity of soil organic carbon (SOC) decomposition will influence the accuracy of the quantitative prediction of carbon (C) balance between ecosystem C fixation and decomposition in a warmer world. However, a consensus has not yet been reached on the temperature sensitivity of SOC decomposition with respect to SOC quality. The fundamental principles of enzyme kinetics sugges...
