Invasive species management is promoted as a general practice to maintain rangeland biodiversity and mitigate livestock performance losses (e.g., weight gain) stemming from invasive-species effects (e.g., competitive exclusion of palatable forages). It is hypothesized that altering fire-timing (e.g., moving from early to late-growing season burning...
Article
Variation in the relative abundance and biomass of arthropods has important potential consequences for insectivores. We studied the influence of temporal variation and habitat management (i.e., burning and strip-disking) on the availability of potential arthropod prey for brooding northern bobwhites (Colinus virginianus) in the mixed-grass prairie...

Full-text available
Movement and selection are inherently linked behaviors that form the foundation of a species' space-use patterns. Anthropogenic development in natural ecosystems can result in a variety of behavioral responses that can involve changes in either movement (speed or direction of travel) or selection (resources used) which in turn may cause population...
Article
Full-text available
Insectivores gain macronutrients and elements from consuming arthropod prey, but must also deal with indigestible components (i.e., exoskeleton) of prey. For example, avian chicks (e.g., northern bobwhites; Colinus virginianus) have limited gut space, and ingesting prey with relatively higher proportions of indigestible components may impact assimi...
Article
All animals must select sites to rest and may spend a large portion of their lives doing so. Despite the importance of this period in their daily activity budget, we lack information about rest/roost ecology for most animals, including the imperiled lesser prairie-chicken (Tympanuchus pallidicinctus; hereafter “LEPC”). Therefore, we sought to ident...
Article
Sand shinnery oak (Quercus havardii) shrublands are estimated to have once occupied 5−7 million ha across the southwestern United States. As a result of herbicide and plowing, this endemic vegetation community has been significantly reduced in extent. Further, sand shinnery oak shrublands were historically maintained by relatively frequent fires, b...
