Centrifuge Modeling of Soil Response to Tsunami-like Rapid Flooding and the Subsequent Drawdown

Creator:: Exton, Margaret C.
Abstract:: Soil instability from tsunami hazards causes substantial damage to coastal infrastructure (e.g., the damage caused by the 2011 Great East Japan Tsunami, or the Heisei Tsunami). Tsunamis are unpredictable, so it is difficult to obtain field-scale measurements. Simulating tsunamis in a laboratory setting is therefore important to further understanding of...

UVB Radiation Affects the Quality of the Female Sexual Attractiveness Pheromone of the Red-Sided Garter Snake

Creator:: Vigeland, Anna E.
Abstract:: In this study, pheromone and skin lipid samples collected from red-sided garter snakes (Thamnophis sirtalis parietalis) were exposed directly to either full-spectrum light or full-spectrum plus UVB light. In addition, female and male snakes were exposed to daily doses of either full-spectrum or full-spectrum and UVB light, after which the...

Phenotypic variation in the sexual attractiveness pheromone of the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: LeMaster, Michael P.
Abstract:: Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...

Sperm depletion and sperm competition in the red-sided garter snake, Thamnophis sirtalis parietalis

Creator:: Kerns, Amelia R.
Abstract:: Sperm competition is the post-copulatory analog of male-male combat, wherein sperm from more than one male coincide in a female’s reproductive tract and compete with one another for fertilization of a limited number of ova. Post-copulatory sexual selection, such as sperm competition, can be a powerful driving force for the...

Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

Creator:: Abdollahi, Abbas
Abstract:: Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...

Patterns and mechanisms : postcopulatory sexual selection and sexual conflict in a novel mating system

Creator:: Friesen, Christopher R.
Abstract:: Postcopulatory sexual selection—sperm competition and cryptic female choice—has become a major area of research over the past 40 years. Within this field there are many outstanding questions at every level of analysis, from proximate to ultimate. The fitness consequences for both sexes in the period after copulation and before fertilization...

Stress and reproduction in male garter snakes

Creator:: Moore, Ignacio T.
Abstract:: Animals respond to stressful situations with increases in plasma levels of glucocorticoid stress hormones. These hormones originate from the adrenal cortex in response to stimulation of the hypothalamic-pituitary-adrenal axis. Glucocorticoids (corticosterone in reptiles) function to mobilize energy and suppress unnecessary functions until the stress passes. Among these immediately unnecessary functions...

Near-Surface Response of Beach Sand : An Experimental Investigation

Creator:: Adams, Rachel Katie
Abstract:: The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...
