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.

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...

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...

Understory response to tree harvesting in pinyon-juniper woodlands

Creator:: Everett, Richard L.
Abstract:: Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

Physiological ecology and structure of benthic communities in a woodland stream

Creator:: Reese, Weldon Harold
Abstract:: This thesis reports a portion of a general ecological study of a stream under conditions of controlled flow and low levels of organic enrichment. It is concerned with the effects of experimental variations of light intensity and concentration of soluble organic enrichment imposed on seasonal variations of temperature and total...
