Mutual mate choice in a terrestrial salamander, Plethodon shermani, with long-term sperm storage

Creator:: Eddy, Sarah L.
Abstract:: Sexual selection can influence the mating system of an organism through multiple mechanisms. These mechanisms result in variation in reproductive success among individuals, and include scramble competition, endurance rivalries, contests, mate choice and cryptic choice, and sperm competition. Understanding the mating system of a species requires the identification of which...

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...

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...

Pheromone mechanisms and behavioral strategies for maximizing courtship success in a terrestrial salamander, Plethodon shermani

Creator:: Vaccaro, Elyse A.
Abstract:: Darwin devised the evolutionary theory of sexual selection to account for the manifold extravagances of courtship behaviors and displays. Mating interactions represent a major evolutionary process driving the elaboration, vibrancy, and peculiarity of these courtship traits. For my dissertation research, I strived to elucidate the dynamics that constitute the complex...

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...

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...

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...

Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

Creator:: Kiemnec, Karen M.
Abstract:: Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

Evolution of a pheromone signaling system in the salamander genus Plethodon (Amphibia: Plethodontidae)

Creator:: Picard, Amy L.
Abstract:: Animal signaling systems frequently utilize multiple traits to produce and transmit a signal. These system elements may span multiple levels of organization. Functional integration of these traits may be expected to generate concordance in evolutionary pattern among system elements, such that evolutionary change in one system component is correlated with...

Selection on larval and adult body size in a marine fish: potential evolutionary responses and effects on population dynamics

Creator:: Johnson, Darren W.
Abstract:: Many species have complex life cycles in which a dispersive larval stage is followed by a relatively sedentary adult stage. For such species, reproductive output is often high and large variation in survivorship throughout early life-history phases (eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...
