Avian response to landscape change in fragmented southern Great Plains grasslands
Coppedge, Bryan R.; Engle, David M.; Masters, Ronald Edward; Gregory, Mark (Ecological Society of America, 2001)We examined the dynamics of avian communities associated with fragmented grasslands in Oklahoma, USA, using long-term (1965-1995) raw (stop-level) data from the Breeding Bird Survey (BBS). Aerial photography was used to ... -
Eastern Redcedar Encroachment Dynamics and Fuel Loading in the North-central Cross Timbers of Oklahoma, Usa.
Hoff, Daniel L. (2017-12-01)Cross Timbers oak forests were historically the transition zone between the eastern deciduous forest and the southern Great Plains, and were typically dominated by Quercus stellata and Q. marilandica. The shift in human ... -
Effects of tail loss on sprint speed, mating strategies, and territory size and quality in the lizard Uta Stansburiana
Anderson, Matthew L. (2013-05)Scope and Method of Study: The study was primarily a field based effort to monitor and document changes in the behavior, mating strategies, and territory size and quality of a population of the lizard Uta stansburiana ... -
Possible sexual selection in pre-reproductive hatchling collared lizards (Crotaphytus collaris)
Crosby, Andrea Acevedo (2015-07)We studied the possible adaptive significance of precocial sexual signaling in collared lizard hatchlings. Male hatchlings display intense dorsolateral orange bars at hatching or within the first weeks of life. Hatchling ... -
Remote sensing application in biomass crop production systems in Oklahoma
Foster, Anserd Julius (2013-12)This study was conducted to evaluate the combined effects of nitrogen and cropping systems on biomass yield and quality and to describe the spatial variation of biomass yield, soil carbon and nitrogen within a switchgrass ... -
Spatial and temporal components of environmental predictors in species distribution modeling: a case study using Bell's Vireo (Vireo bellii)
Walker, Cassondra M. (2018-12)The largest threats to biodiversity are global climate change and habitat loss, both of which are global concerns due to decreases in species’ populations. Understanding species’ responses to both threats is needed and a ...
