The Complexity Of Female Treefrog Mate Choice: Choosiness And Preferences Are Independent Behaviors And Each Are Prone To Separate Sources Of Variation, Olivia S. Feagles
The Complexity Of Female Treefrog Mate Choice: Choosiness And Preferences Are Independent Behaviors And Each Are Prone To Separate Sources Of Variation, Olivia S. Feagles
Theses and Dissertations
Mate choice is an important cause of natural and sexual selection, driving the evolution of ornaments and promoting diversification and speciation. Mate choice decisions arise from the interaction of several components, and knowledge of whether they interact, and how, is crucial for understanding their contributions to selection. There are multiple components of mate choice theoretically proposed, and here I focus specifically on preference functions (attractiveness ranking of prospective mates) and/or choosiness (willingness to invest effort in obtaining the preferred mate). Objective 1 (addressed in Chapter I) of this dissertation focuses specifically on the relationship between preferences and choosiness, testing the …

Architecture Of Mate Choice Decisions In Enchenopa Treehoppers, Bretta Speck
Theses and Dissertations
Mate selection is one of the most important choices a female can make for herself and her offspring. Variation in mate choice decisions has consequences for the maintenance of and the diversity within a population and the promotion of divergence between populations. Mate choice decisions arise from the interaction of two main components: “mate preferences” (the relative attractiveness of a potential mate) and “choosiness” (the effort put into procuring a preferred mate). My dissertation analyzes the relationship between the components involved in female mate choice decisions in Enchenopa binotata treehoppers. I take a three-pronged approach. First, I investigated how E. …
Sources Of Variation In Social Plasticity In Female Mate Preferences And Male Traits, Daniel Neelon
Sources Of Variation In Social Plasticity In Female Mate Preferences And Male Traits, Daniel Neelon
Theses and Dissertations
Female preferences are an important cause of selection on male traits, and exploring the sources of variation in these preferences has been the focus of intense behavioral research. This is due to the fact that understanding this variation is integral to understating the maintenance of variation and complexity in male traits, as well as the evolution and divergence of populations. This project aims to explore the sources of variation in these mating preferences, as well as examine whether similar sources affect components of male traits. This was accomplished using the well-studied mating system of the Green Treefrog, Hyla cinerea that …
Influence Of Natural And Anthropogenic Light Levels On Female Preferences In Eastern Gray Treefrogs (Hyla Versicolor), Victoria Underhill
Influence Of Natural And Anthropogenic Light Levels On Female Preferences In Eastern Gray Treefrogs (Hyla Versicolor), Victoria Underhill
Theses and Dissertations
Chapter 1: While the influence of environmental variables, particularly temperature and rainfall, on the breeding behavior of amphibians is widely recognized, relatively few studies have addressed how the moon affects amphibian behavior. Yet, the lunar cycle provides several rhythmic temporal cues that animals could use to time important group events such as spawning, and the substantial changes in light levels associated with the different moon phases may also affect the behavior of nocturnal frogs. Using seven years of field observation data, we tested for lunar effects on the reproductive activity of male and female Eastern gray treefrogs (Hyla versicolor). We …
