Effect of competition for an automated supplement feeder on supplement intake behavior of beef stocker steers
(2019-12)The objective of this research was to determine the effect of competition for a feeding space at an automated supplement feeder on supplement intake behavior. A 2-yr study was conducted; each yr, 128 mixed-breed beef steers ... -
Effects of Extended Water Restriction on Performance, Behavior, Health, and Welfare of Feedlot Steers
(2019-07)Climate change and a growing human population are expected to impact water availability globally, which could limit water resources for animal agriculture. As water resources become scarcer, methods to efficiently utilize ... -
Epigenetic Effects of Paternal Perception of Predation Risk on Offspring Development, Stress Reactivity, and Neural Gene Expression
(2019-07)In stable environments, parents able to transmit information such as predation risk should have offspring that are pre-adapted to the environment they will encounter as adults. While intergenerational epigenetic transmission ... -
Equine preferences for food rewards versus human contact and implications for interspecies social bonding
(2019-12)The primary focus of the dissertation is to study horse preference for human contact versus food rewards. The study uses horses' ability to differentiate between visual symbols with different meanings in order to test the ... -
Genetic Determination Vs. Flexibility: How Plastic Are Behaviors and Underlying Physiological Mechanisms in a System of Locally Adapted Populations?
(Oklahoma State University, 2014-07-01)An important goal in evolutionary biology is to conceptually incorporate phenotypic plasticity into the framework of trait evolution. Here, I used a system of extremophile fish, Poecilia mexicana, locally adapted to all ... -
Individual variation in the call characteristics of American toads (Anaxyrus americanus)
(2022-12)Recent studies in animal behavior have demonstrated that behaviors are often repeatable. Variation in behaviors arise at many levels, including the level of a single individual, and between individuals in a population. ... -
Influence of Divorcing Parents' Post-Separation Dating Relationships on Children's Behavior
(2019-07)Divorce for many families is a common life trajectory, with divorce rates being about half of first marriages (Amato, 2010; Frisby, Booth-Butterfield, Dillow, Martin, and Weber, 2012). On average, children from divorced ... -
Influence of Hormones and Nutrition on Communication Signal Development in Green Anoles (Anolis Carolinensis)
(Oklahoma State University, 2013-05-01)Green anoles utilize highly stereotyped species specific displays for both intersexual and intrasexual communication. These displays have garnered much attention from researchers; however, to date no one has conclusively ... -
Predator induced phenotypic plasiticity within and between generations in the pond snail Physa acuta
(2022-05)Prey often induce changes in the phenotype of their prey through phenotypic plasticity. Phenotypes that change include life history traits, morphology, and behavior, and changes may be adaptive or non-adaptive. The goal ... -
Response to intervention for behavioral concerns
(2011-05)In response to the problems surrounding the discrepancy model, IDEA now allows response to intervention (RTI) as an alternative means to identify students with learning disabilities. In research a RTI approach has been ... -
Scientific realism and final causes: A new method for visualizing final causes in iconic models
(2021-12)In light of documented methodological issues and reproducibility failures, psychologists have sought to improve the scientific credibility of their field. Unfortunately, these efforts have not addressed psychology's ... -
Sex steroid hormones, architects of behavior and development: A look at the effects of sex steroid hormones in a lizard model
(2022-05)The mechanisms of sex determination and differentiation in reptilian groups are diverse and largely not well understood. With this study, we hoped to identify to what extent these mechanisms may be overridden by hormonal ... -
Teachers expectations for students with externalizing and internalizing behaviors
(2014-05)The purpose of this study was to determine if elementary school teachers held differential expectations for children labeled with emotional disturbance, and externalizing or internalizing behavior characteristics. This ... -
Treatment integrity and child outcomes: Conjoint behavioral consultation in an urban setting with clients of ethnic minority status
(2008-12)Scope and Method of Study: Home and school represent two of the most powerful influences in children's lives. Research indicates that students benefit when there is a collaborative relationship between families and educators ...
