Life in a Rapidly Changing Environment: The Thermal Biology of the Red-sided Garter Snake (Thamnophis sirtalis parietalis)

Creator:: Hubert, David L.
Abstract:: At a time when environmental conditions are rapidly changing, understanding how thermal extremes impact wildlife is imperative to fully understanding the consequences of climate change in natural ecosystems. While many organisms are currently impacted by rapidly warming and more erratic environmental conditions, identifying and investigating model species whose life histories...

The ontogeny and mediation of sexual size dimorphism in the red-spotted garter snake, Thamnophis sirtalis concinnus

Creator:: Lerner, Darren T.
Abstract:: A wide range of environmental and physiological factors influence the type and extent of sexual dimorphism found in animals. Influential factors include variable climate, competition for resources and mates, mate choice, and parental investment. In addition, some investigators attribute differences in body size to physiological factors influenced by genetic and...

Reproductive implications of parasitic infections and immune challenges in garter snakes

Creator:: Uhrig, Emily J.
Abstract:: Parasitic infections and immune challenges can affect host reproductive fitness and, ultimately, the evolution of host populations in a myriad of ways. The fitness implications of parasitic infections range from increased host mortality to subtle changes in reproductive investment. From alterations of behaviors, sexual signaling, and competitive ability to changes...

Life History of the Northern Rubber Boa (Charina bottae) in Oregon

Creator:: Leppin, Mark V.
Abstract:: The Northern Rubber Boa (Charina bottae) is a small, secretive boa native to the Pacific Northwest. Despite this being possibly the highest latitude boas and one of only two boas native to the continental U.S., it has received surprisingly little attention. Most of the research on the natural history of...

Behavioral adaptations and the minimization of reproductive costs in the male red-sided garter snake, Thamnophis sirtalis parietalis.

Creator:: O'Donnell, Ryan P.
Abstract:: The benefits of reproduction are clear, but there are also costs. Much is known about the costs of reproduction in females, but only recently have male costs been investigated in any depth. These costs of reproduction may be minimized by appropriately modifying behavior, but there has been little research on...

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...

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...

Pheromonal mediation of reproductive behavior in the brown tree snake

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...

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...
