Noise and signal transmission properties as agents of selection in the vibrational communication environment
(University of Missouri--Columbia, 2007)
Members of the Enchenopa binotata species complex (Hemiptera: Membracidae) are host-specific phytophagous insects that communicate by sending vibrations through their host plants. Successful communication depends on the ...
Collective offspring-parent signaling in a social treehopper : mechanisms, patterns and function
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] I investigated the properties of collective behavior in a group-living insect, including the patterns of group behavior, the function of group level ...
Diversification in plant feeding insects : patterns of host-plant specialization and mating signal evolution inferred from species-level phylogeny and population genetics
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Speciation yields two reproductively isolated groups capable of living in sympatry without cross-fertilization. Thi inability to hybridize is caused ...
Age effects on reproductive behavior in the treehopper umbonia crassiscornis (Hemipera: membracidae)
(University of Missouri--Columbia, 2007)
In many animal species females select mates based on male age. This choice is often linked to the reproductive benefits females derive. Age-based choice is also influenced by variation in the ability of males to find and ...
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 ...
Communication about predation risk between parents and offspring groups in treehoppers
(University of Missouri--Columbia, 2011)
False alarms should be common and costly for group-living animals, but to limit false alarms, animals must evade a tradeoff between response sensitivity and accuracy. I investigated this topic in two closely-related species ...
Localization mechanisms of small plant-dwelling insects
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Movement is the basis of animal ecology, and understanding the causes and consequences of animal movement is a major goal of ecological research. ...
