Another tool in the toolbox? Using fire and grazing to promote bird diversity in highly fragmented landscapes
(Ecological Society of America, 2011-03-08)The grasslands of central North America have experienced drastic reductions in extent, removal of historic disturbance patterns, and homogenization of remaining fragments. This has resulted in steep declines for a broad ... -
Distribution of resprouting woody plants and the effect of fire on vegetation types in the Southern Great Plains
(2021-07)The effects of soil, topography, and fire on woody plant distribution and extent has been studied over numerous systems; however, most literature has focused individually on these influencing variables at single sites. In ... -
Grassland heterogeneity and pyric herbivory: Implications for ungulate movement, biodiversity conservation, and rangeland productivity in the Anthropocene
(2022-05)How to simultaneously manage grasslands for sustained livestock productivity and biodiversity conservation is a persistent dilemma for rangeland ecologists and conservationists. Moreover, climate change and invasive species ... -
Impact of Diagenetic Overprints on Reservoir Quality and Heterogeneity, Upper Morrow Sandstone, Morton County, Kansas
(Oklahoma State University, 2011-12-01)Integrated analysis of three cores along with well logs yielded eight distinct lithofacies associated with fluvial, estuarine and marine environments of deposition. The marine facies M-1 and M-2, which are fossiliferous ... -
Interaction of fire and grazing in Oklahoma Artemisia filifolia shrubland
(2010-12)Scope and Method of Study: We conducted research in Artemisia filifolia shrublands located in Woodward County, Oklahoma to determine the effect of restoring the fire-grazing interaction on vegetation structure. Data were ... -
New stochastic pore-scale simulation and machine learning approach to predicting permeability and tortuosity of heterogeneous porous media
(2023-05)A new 3D stochastic pore-scale simulation approach was introduced in this study to investigate how stochastic pore connectivity impacts the permeability and hydraulic tortuosity of heterogeneous porous media. Multiple ... -
Spatial and temporal variability in environmental conditions and its influence on the habitat selection and reproduction of the greater prairie-chicken
(2020-12)Spatial and temporal heterogeneity in resource availability and environmental conditions are key determinants of the distribution of many organisms and in-part shapes ecosystem function. As a result, understanding how ... -
Spatial heterogeneity and scale-dependent habitat selection for two sympatric raptors in mixed-grass prairie
(Wiley Open Access, 2017-07-15)Sympatric predators are predicted to partition resources, especially under conditions of food limitation. Spatial heterogeneity that influences prey availability might play an important role in the scales at which potential ... -
Ungulate preference for burned patches reveals strength of fire-grazing interaction
(Wiley Open Access, 2011-08-12)The interactions between fire and grazing are widespread throughout fire-dependent landscapes. The utilization of burned areas by grazing animals establishes the fire-grazing interaction, but the preference for recently ...
