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 ...
Temporal variability in aboveground plant biomass decreases as spatial variability increases
(Ecological Society of America, 2016)
Ecological theory predicts that diversity decreases variability in ecosystem function. We predict that, at the landscape scale, spatial variability created by a mosaic of contrasting patches that differ in time since ...
Spatial heterogeneity increases diversity and stability in grassland bird communities
(Ecological Society of America, 2015)
Grasslands are inherently dynamic in space and time, evolving with frequent disturbance from fire and herbivores. As a consequence of human actions, many remaining grasslands have become homogenous, which has led to reduced ...
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 ...
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 ...
Rising Great Plains fire campaign: Citizens' response to woody plant encroachment
(Ecological Society of America, 2013)
Despite years of accumulating scientific evidence that fire is critical for maintaining the structure and function of grassland ecosystems in the US Great Plains, fire has not been restored as a fundamental grassland process ...
Landowners' perceptions of risk in grassland management: Woody plant encroachment and prescribed fire
(Resilience Alliance, 2014)
Ecologists recognize that fire and herbivory are essential to maintaining habitat quality in grassland ecosystems. Prescribed fire and grazing are typically used on public reserves to increase biodiversity, improve grassland ...
