Abiotic and biotic drivers of grassland structure: from individual to community responses
(2021-11-02)Climate has long been recognized as an important factor in determining the spatial-temporal distribution and abundance of species, consequently influencing global biological diversity. Model projections point to changes ... -
Belowground meristem density of warm-season grasses as regulators of grassland invisibility
(2013-05)Recent studies suggest that perennial grasslands susceptibility to invasions (i.e. invasibility) by exotic plants may be related to the population of native grass belowground meristems (the "bud bank") in these plant ... -
Comparative Sampling Methods and Community Composition of Grasshoppers (Orthoptera: Acrididae) in Northern Bobwhite Habitat
(Oklahoma State University, 2014-05-01)This research contributes to a larger body of work concerning the decline of Northern Bobwhite in Western Oklahoma. Populations of Northern Bobwhite have been declining since at least the 1960's. Previous research has ... -
Effects of ecological management on tallgrass prairie butterflies and their nectar sources
(2010-05)Scope and Method of Study: -
Experimental tree removal in tallgrass prairie: Variable responses of flora and fauna along a woody cover gradient
(Ecological Society of America, 2012)Woody plant encroachment is a worldwide phenomenon in grassland and savanna systems whose consequence is often the development of an alternate woodland state. Theoretically, an alternate state may be associated with changes ... -
Interactive effects of grazing and burning on wind- and water-driven sediment fluxes: Rangeland management implications
(Ecological Society of America, 2011)Rangelands are globally extensive, provide fundamental ecosystem services, and are tightly coupled human-ecological systems. Rangeland sustainability depends largely on the implementation and utilization of various grazing ... -
Native Legumes Versus Lespedeza cuneata: Implications for Ecosystem Services
(2019-07)Grasslands are the most threatened ecosystem worldwide due to habitat fragmentation and alteration, which have contributed to the spread of invasive plants. Fire is historically important in maintaining grasslands, and can ... -
Plants regulate grassland arthropod communities through biomass, quality, and habitat heterogeneity
(2019-10-16)Habitat heterogeneity affects both biotic and abiotic factors important in determining arthropod community composition. In a sandy, mixed‐grass prairie in the southern Great Plains, we used clipping and NPK fertilization ... -
Pyric-carnivory: Raptor use of prescribed fires
(Wiley Open Access, 2017-11)Fire is a process that shaped and maintained most terrestrial ecosystems worldwide. Changes in land use and patterns of human settlement have altered fire regimes and led to fire suppression resulting in numerous undesirable ... -
RESPONSES OF COMMUNITY STRUCTURE AND ECOSYSTEM FUNCTIONING TO CLIMATE CHANGE – META-ANALYSIS, MODELING, EXPERIMENTAL STUDY AND DATA-MODEL FUSION
(2015)Observations, experimental studies and modeling endeavors all show that global climate change, mainly increased surface air temperature and associated change in precipitation regime, has caused impacts on plant community ... -
Small mammal herbivores mediate the effects of soil nitrogen and invertebrate herbivores on grassland diversity
(2019)Simultaneous reductions in herbivore abundance and increases in nitrogen deposition have led to radical shifts in plant communities worldwide. While the individual impacts of these human‐caused disturbances are apparent, ... -
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 ...
