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 ... -
Chromatin-level regulation of the maize purple plant1 gene
(University of Missouri--Columbia, 2008)In eukaryotes, gene expression is controlled at the chromatin level by mechanisms that are not yet well understood. This study addressed some of the unanswered questions about chromatin-level gene regulation. In maize, the ... -
The evolutionary significance of developmental plasticity in the communication system of Neoconocephalus triops (Orthoptera: tettigoniidae)
(University of Missouri--Columbia, 2008)The katydid Neoconocephalus triops is a tropical species that extended its distribution range to North America. In North America, males display developmental plasticity in mating calls between reproductive generations: the ... -
Mating systems in Nicotiana longiflora and N. Plumbaginifolia : the effect of interspecific interactions
(University of Missouri--Columbia, 2008)The research presented here was focused on the effects of interactions between Nicotiana longiflora and N. plumbaginifolia on their mating systems. First, I conducted a series of observations and pollination experiments ... -
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological ... -
Role of transmembrane protein strabismus in motor neuron migration in the zebrafish hindbrain
(University of Missouri--Columbia, 2008)Nervous system development involves extensive cell migration, causing immature neurons to move from proliferative zones to specific locations to generate functional circuits. Defective in neuronal migration can cause severe ...
