Aggressive calling in treefrogs
(University of Missouri--Columbia, 2011)Acoustic communication plays a major role in many of the social activities of frogs. A great deal is known about communication in some contexts, such as mate choice. Aggressive communication, however, has received little ... -
Behavioral consequences of polyploidy in hyla chrysoscelis treefrogs : implications for speciation and underlying mechanisms
(University of Missouri--Columbia, 2015)Polyploidy occurs when organisms have more than the typical two copies chromosome sets. Polyploidy has occurred many times throughout plant and vertebrate evolution, and recently in diverse families of frogs. Male treefrogs ... -
Behavioral endocrinology of female gray treefrogs, Hyla versicolor, in response to acoustic stimulation
(University of Missouri--Columbia, 2008)Particularly in organisms with a limited breeding period, females must rely on both external and physiological cues to regulate the phenology of reproduction and behavior. I investigated the relationship between male ... -
Call timing interactions, aggressive behavior, and the role of acoustic cues in chorus formation in treefrogs
(University of Missouri--Columbia, 2008)I studied calling patterns and aggressive behavior of the Bird voiced treefrog, , to assess how dynamic call characters influences males and the factors influencing the onset of choruses and settling patterns of males in ... -
Coordinated communication: an analysis of signal and preference phenotypes in the genus Hyla
(University of Missouri--Columbia, 2014) -
Integration of methods to study mate choice behavior in treefrogs
(University of Missouri--Columbia, 2014)My research incorporates results from a variety of methods to understand behavior. In my dissertation, I examined female behavior to novel, complex calls. In the gray treefrog species complex, Hyla versicolor and H. ... -
Phylogenetic and behavioral differentiation in the canyon treefrog, Hyla arenicolor
(University of Missouri--Columbia, 2011)My research interests lie in understanding the process of speciation. In my dissertation I set out to do this by examining the first step in potential speciation, population differentiation. In my dissertation research I ... -
Postcopulatory sexual selection in the soldier fly Merosargus cingulatus
(University of Missouri--Columbia, 2011)My dissertation research focuses on the largely understudied field of postcopulatory (or "cryptic"') mate choice. As part of my dissertation research, I have developed a novel model system for the study of postcopulatory ...
