Latent effects of larval experience: The pervasive effects of tadpole predation risk on frog phenotype
Beaty, Lynne (2017-05)Predation risk influences prey phenotype. Predator-induced changes in prey behavior and morphology are hypothesized to be adaptive, as long as predation risk is constant. This restriction does not hold for organisms like ... -
Morphospace Oddity: Assessing Morphological Disparity of the Cimolodonta (Multituberculata) Across the Cretaceous-Paleogene Extinction Boundary.
Levering, David A. (Oklahoma State University, 2013-07-01)In this study, I focus on the loss of species diversity - and therefore morphological diversity - within the Cimolodonta (Multituberculata) during the Cretaceous-Paleogene (K-Pg) extinction, followed by their recovery in ... -
Multi-scale examination of stopover habitat use by migrant shorebirds
Albanese, Eugene (2011-12)Scope and Method of Study: Surveys of wetland stopover habitats for migrant shorebirds were conducted within broad-scale landscapes in north-central Oklahoma from 2007 thru 2009. The response of wetland shorebird habitat ... -
Personality influences anti-predator response in snails
Schmidt, Lauren (2016-02-15)Animals have many strategies to protect themselves against predators, such as avoidance and refuge-seeking behaviors. Animal personality, which is defined as a set of consistent behaviors, is a framework that has been used ... -
Predator induced phenotypic plasiticity within and between generations in the pond snail Physa acuta
Goeppner, Scott R. (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 ... -
Quantifying Behavioral Isolation Between Closely Related Species of Mice
Ryan, Tyler D. (2018-12-01)Mate choice, the propensity of one individual to preferentially mate with another individual that expresses certain phenotypic values, can be a strong force in promoting or limiting gene flow between species. Individuals ... -
Reproductive life history decisions and success of freshwater pond snails (Physa acuta) during chronic zinc exposure
Wells, Allison (2019-12)Life history theory examines how individuals should make trade-offs between current reproductive effort and survival to achieve future reproductive gains. A prediction is that as future life expectancy decreases, individuals ... -
Seasonal Dynamics of the American Burying Beetle (Nicrophorus Americanus) in Eastern Oklahoma
Ferrari, Thomas (Oklahoma State University, 2014-12-01)American Burying Beetle (ABB) (Nicrophorus americanus) populations have been in decline since the early 1900's, and much effort has been put into studying the survival of this now endangered species. Burying beetles ... -
Sericea lespedeza (Lespedeza cuneata) invasion: Implications for a small mammal community and the influence of local fire history
Howard, Jeffrey M. (2013-12)Lespedeza cuneata [(Dumont) G. Don] is a perennial legume first introduced to North America from eastern Asia in 1896 and is now widespread and well established across much of the eastern and central United States. Possible ... -
Spatial and temporal variability in environmental conditions and its influence on the habitat selection and reproduction of the greater prairie-chicken
Londe, David W. (2020-12)Spatial and temporal heterogeneity in resource availability and environmental conditions are key determinants of the distribution of many organisms and in-part shapes ecosystem function. As a result, understanding how ... -
Species history, population genetics, and behavioral reproductive isolating mechanisms of two Chihuahuan desert katydids (Orthoptera: Tettigoniidae)
Kensinger, Bart J. (2015-05)Understanding the mechanisms and evolutionary processes that lead to reproductive isolation between populations is the major goal of speciation research. Here, I integrated approaches from phylogenetics, population genetics, ... -
Test of the Habitat Association and Seasonal Activity of the American Burying Beetle (Nicrophorus americanus) at Camp Gruber, OK, and the Benefits of Nicrophorus to Soil Fertility
Freeman, Lexi (2018-05-01)Within the past decade, the American burying beetle, Nicrophorus americanus (ABB) have disappeared from approximately 90% of its former range. Efforts have been made to protect existing populations in the wild; however, ... -
Timing of maternal and paternal predator exposure and resulting transgenerational effects in Physa acuta
Najar, Jamie (2022-05)The interactions that an individual has with its environment can impact the physical traits and behaviors of both that individual and its offspring. This phenotypic plasticity can influence the evolution of a population, ...
