The Effects on Hybridization and Speciation in the Hawaiian Cricket Laupala (subfamily: Trigonidiinae)
Title of Document: MATING COSTS, MALE CHOICE DISPLACEMENT, AND THE EFFECTS ON HYBRIDIZATION AND SPECIATION IN THE HAWAIIAN CRICKET LAUPALA (SUBFAMILY: TRIGONIDIINAE) Jenna Jadin, Doctor of Philosophy, 2009 Directed By: Dr. Kerry L. Shaw, Professor Behavior, Ecology, Evolution & Systematics Contact zones between two closely-related species provide unique laboratories for studying the processes o...
متن کاملWing resonances in the Australian field cricket Teleogryllus oceanicus.
The anatomy and mechanics of the fore-wings of the Australian cricket Teleogryllus oceanicus were examined to study how resonances of the wings were excited, to model the interactions between the two wings during sound production, to account for the frequency changes that occur within the pulses and to determine the variation in sound amplitude during the pulses. Sound is produced after raising...
متن کاملThe genetics of speciation: genes of small effect underlie sexual isolation in the Hawaiian cricket Laupala.
Sexual behaviours often evolve rapidly and are critical for sexual isolation. We suggest that coordinated sexual signals and preferences generate stabilizing selection, favouring the accumulation of many small-effect mutations in sexual communication traits. Rapid radiation of a sexual behaviour used in signalling, song pulse rate, has been observed in the Hawaiian cricket genus Laupala. Using ...
متن کاملTissue-Specific Transcriptomics in the Field Cricket Teleogryllus oceanicus
Field crickets (family Gryllidae) frequently are used in studies of behavioral genetics, sexual selection, and sexual conflict, but there have been no studies of transcriptomic differences among different tissue types. We evaluated transcriptome variation among testis, accessory gland, and the remaining whole-body preparations from males of the field cricket, Teleogryllus oceanicus. Non-normali...
متن کاملRecognition of courtship song in the field cricket, Teleogryllus oceanicus
The courtship song of the cricket, Teleogryllus oceanicus plays an important role in inducing the female to mount the male, which is necessary for mating. The song consists of a short, amplitude-modulated chirp, followed by a long trill of constant intensity and high syllable rate. Using playback techniques, it was determined which physical parameters of courtship song are necessary and/or suff...
