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...

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...

Adaptive diversity and divergence at frog antimicrobial peptide loci

Creator:

Tennessen, Jacob A.

Abstract:

In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...
