Aflatoxins in wildlife feed: Know how to protect wildlife
Dale, Leah L.; O'Connell, Timothy J.; Elmore, Dwayne (Oklahoma Cooperative Extension Service, 2021-08) -
Avian response to old world bluestem (Bothriochloa ischaemum) monocultures in mixed-grass prairie
George, Andrew D. (Oklahoma State University, 2009-07-01)Despite persistent and widespread declines of grassland birds in North America, few studies have assessed differences between native and exotic grasslands as songbird habitat. In the Great Plains, many fields enrolled in ... -
Avian responses to fire frequency in the Oklahoma Cross Timbers
Laughlin, Caitlin Berry (2018-05)Disturbance in the form of fire is an important ecological process. The presence or long term absence of fire is an important determinant of forest vegetative cover by mediating regeneration, tree establishment, and canopy ... -
Bird Community Index using life history guilds of breeding birds in Taiwan
Hildebrand, Kelsey Nicole (2016-05-06)As humans continue to expand our range, biodiversity is suffering. In order to preserve biodiversity, it becomes necessary to set aside land for preservation. In Taiwan, there is currently a corridor of preserved landscapes ... -
Bird-window collisions: Field testing a potential solution and evaluating stakeholder perceptions
Riggs, Georgia J. (2021-07)Bird-window collisions are a major source of human-caused avian mortality for which there are multiple mitigation and prevention options available. Despite growing availability of products designed to reduce collisions, ... -
Diversity, relative abundance, movement, and fitness of insect predators in winter canola agricultural landscapes in the United States Southern Plains
Jessie, Casi Nichole (2017-05)In general, landscape diversification in agricultural production systems is possibly correlated with increased biological pest suppression services. In the Southern Great Plains, continuous winter wheat systems are being ... -
Factors Affecting Bird-Window Collisions in a Small Urban Area: Stillwater, Oklahoma
Riding, Corey S. (2019-05-01)This dissertation consists of four concurrent studies of bird-building collisions, which primarily occur at glass surfaces (e.g., windows) and are a major source of direct anthropogenic mortality for birds globally. Although ... -
Giving up density as an indicator of black bear food preference in the Ouachita National Forest, SE Oklahoma
Prentiss, Natasha (2019-05-10)Living in close proximity to humans can present costs to wildlife species but can also present benefits in the form of reliable, human-generated, food subsidies. Black bears are opportunistic omnivores that have adapted ... -
Group living, parental care, age structure, and genetic relatedness in Liolaemus leopardinus, a high-elevation lizard from the Andes of Chile
Santoyo Brito, Enrique (2017-12)Social behavior refers to any interactions between two or more conspecifics. A relatively common social behavior in the animal kingdom is group living, which provides benefits to group members (e.g., enhanced vigilance and ... -
Guidelines and recommendations for record keeping and data use for feline trap-neuter-return programs
Schwartz, Katherine (2016-05-03)Feral and free roaming domestic cat (Felis catus) populations are a growing concern for animal welfare, wildlife mortality, and human and domestic animal health. This means that the issue is also a growing topic for ... -
Herbicide Control and Seed Bank Dynamics of Old World Bluestem
Robertson, Scott Gallup (Oklahoma State University, 2009-05-01)The invasive grass Old World bluestem (OWB Bothriochloa ischaemum) threatens native plant and animal diversity. I used single, double, and triple applications of glyphosate in various combinations with and without a mowing ... -
Landscape of fear as an emergent property of heterogeneity: Contrasting patterns of predation risk in grassland ecosystems
Atuo, Fidelis A.; O'Connell, Timothy J. (Wiley Open Access, 2017-05-24)The likelihood of encountering a predator influences prey behavior and spatial distribution such that non-consumptive effects can outweigh the influence of direct predation. Prey species are thought to filter information ... -
Modeling post-CRP land use for optimum environmental benefits
Lungu, Cosmas (2007-05)Scope and Method of Study: Modeling of the Conservation Reserve Program tracts to maintain environmental benefits in Texas County, Oklahoma by using GIS. -
Potential for Aflatoxicosis in Northern Bobwhite (Colinus virginianus) Exposed to Contaminated Grain at Feeding Stations
Dale, Leah Leanne (Oklahoma State University, 2014-07-01)There is concern about the potential impacts that supplemental feeding may have on wildlife populations. Possible negative effects of wildlife feeding include altered fecundity, recruitment, survival, predation, pathogen ... -
Precipitation as a Driver of Avian Community Structure Across Space and Time
Cady, Samantha (2018-05-01)Moisture variability can be a major driver of avian community structure across space by limiting species range edges, and over time by forcing individual movements or temporary species distributional shifts. This study ... -
Riparian Influence on Eastern Forest Songbirds at Their Western Range Limit
Sinnott, Emily Ann (Oklahoma State University, 2014-12-01)The Cross Timbers is a transitional landscape between the eastern temperate deciduous forests and the grasslands of the Central Great Plains. Here many eastern forest birds reach the western edge of their breeding ranges. ... -
Small mammal communities and functional connectivity in the Lower Rio Grande Valley: A landscape perspective
Dolman, Richard William (2015-07)Habitat loss and fragmentation are major threats to global biodiversity, negatively affecting all major taxonomic groups. To mitigate these effects, the United States Fish and Wildlife Service manages three refuges in the ... -
Songbird Community Structure in Cross Timbers Forest: Influence of Juniper Invasion and Urbanization
Heinen, Jason (Oklahoma State University, 2009-12-01)Several species of North American songbirds with population centers in the eastern U.S. reach the southwestern limit of their breeding range in Oklahoma cross timbers forest. Historically, the cross timbers was dominated ... -
Spatial distribution of aerial predators: Influences on usable space for quail
Atuo, Fidelis Akunke (2017-05)The likelihood of encountering a predator influences prey behavior and spatial distribution such that non-consumptive effects can outweigh the influence of direct predation. Prey species are thought to filter information ... -
Spatial heterogeneity and scale-dependent habitat selection for two sympatric raptors in mixed-grass prairie
Atuo, Fidelis A.; O'Connell, Timothy J. (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 ...
