Reproductive life history decisions and success of freshwater pond snails (Physa acuta) during chronic zinc exposure
(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 ...
Insulin-like growth factor 1 and the hormonal mediation of sibling rivalry in eastern bluebirds (Sialia sialis)
(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 ...
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. ...
Evaluation of the effect of silver and silver nanoparticles on the function of selenoproteins using an in-vitro model of the fish intestine: The cell line RTgutGC
(2019-12)
The long-term adverse effects of silver (Ag) and silver nanoparticles (AgNP) on human and environmental health is a concern. Moreover, recent research in mammalian cells has clearly indicated detrimental inhibitory effects ...
Metal speciation’s role in toxicity, bioavailability, and bio-reactivity in the rainbow trout (oncorhynchus mykiss) gut cell line (RTgutGC)
(2020-12)
The bioavailability of metal complexes is poorly understood. To evaluate the bioavailability and toxicity of neutral, and charged metal complexes, as well as free metal ions, Visual Minteq, a chemical equilibrium model, ...
Common carp (Cyprinus carpio) affect water quality and macroinvertebrate communities in Nebraska Sandhill lakes
(2020-05)
Invasive species like the common carp (Cyprinus carpio) threaten the health and integrity of aquatic ecosystems. The Nebraska Sandhills region consists of 57,000 km2 of grass-stabilized sand dunes and topographic lows ...
Extrusion as a Mechanism of Host Immune Response Evasion in a Chlamydia trachomatis Murine Infection Model
(2019-07)
Chlamydia trachomatis is an obligate intracellular organism that is the leading cause of preventable blindness and sexually transmitted bacterial infections. C. trachomatis exhibits a biphasic developmental cycle involving ...
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 ...
Comparison of zooplankton communities in Oklahoma: Implications for paddlefish (Polyodon spathula) management and restoration
(2021-05)
American paddlefish (Polyodon spathula) are large riverine planktivores whose populations have declined significantly over the last century. These declines are largely due to overharvest from commercial fishing and habitat ...
Effect of Fire and Habitat Interaction on Arthropod Forage for Northern Bobwhite Broods
(2019-07)
Arthropods are abundant and diverse animals that dominate many terrestrial food webs and provide important ecosystem functions. Northern bobwhite (Galliformes, Colinus virginianus) chicks and reproducing hens require high ...
