Ecology and Evolution of Phosphorus Use in Daphnia
Sherman, Ryan E. (2019-05-01)Understanding how populations respond to environmental change is an important challenge in contemporary biology. Ecological stoichiometry uses elemental composition of species to make predictions about success in defined ... -
Effects of Supplemental Feeding on Stress Physiology and Nesting Success of Eastern Bluebirds, Sialia Sialis
Perryman, Danielle Claris (2017-05-01)A common anthropogenic influence on wildlife is the use of supplemental bird feeders. Dependent on abundance and natural food availability, this supplemental food source could influence individual survival and productivity. ... -
Epigenetic Effects of Paternal Perception of Predation Risk on Offspring Development, Stress Reactivity, and Neural Gene Expression
Brass, Kelsey Erin (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 ... -
Examining the Existence and Maintenance of Behavioral Syndromes in Eastern Bluebirds (Sialia Sialis)
Pandit, Meelyn Mayank (2017-05-01)Behavioral syndromes are suites of correlated behaviors that can constrain behavioral expression. Constrained behaviors in environments with high levels of human development, which expose individuals to multiple novel ... -
Hidden in plain sight: Morphological and genetic diversity of blood protozoa from North American amphibians
Shannon, Ryan Patrick (2022-12)Blood parasites represent an incredibly diverse subset of parasites that infect all major groups of vertebrates and are transmitted by numerous blood feeding invertebrates. However, quantifying blood parasite diversity is ... -
Insulin-like growth factor 1 and the hormonal mediation of sibling rivalry in eastern bluebirds (Sialia sialis)
Ridenour, Matthew (2020-05)In altricial animals, young are completely dependent on parents for provisioning. Because this provisioning is limited, the ability to outcompete siblings to receive food items and parental attention has clear fitness ... -
Investigating the evolutionary origins and mechanisms underlying xenobiotic sensitivity using resurrection ecology
Simpson, Adam Martin (2017-07)Sensitivity to an organophosphate insecticide, chlorpyrifos, was evaluated in a resurrected population of Daphnia pulicaria; this population originated from a lake that has experienced over a century of cultural eutrophication. ... -
Meningiomas: A biochemical, genetic, and pharmacological review
Fisher, Kylie (2018-04-19)A meningioma is a tumor originating in the meninges that cover the brain and spinal cord. While grade I meningiomas are easily treated with surgery, grade II and III tumors are much more difficult. They are also challenging ... -
Physiological approach to understand the mechanisms of hydrogen sulfide tolerance using a fish study system
Henpita Polwatte Gamarallage, Chathurika Ruchirani (2018-05)Hydrogen sulfide (H2S) is well known as a toxic gas produced by the decomposition of organic matter and geothermal sources and also produced endogenously by cysteine catabolism. Exposure to H2S drives hormetic effects ... -
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 ...
