Screening H3 Histone Acetylation In A Wild Bird, The House Sparrow (Passer Domesticus), Daniella Ray
Electronic Theses and Dissertations
Epigenetic mechanisms are increasingly understood to have major impacts across ecology. However, one molecular epigenetic mechanism, DNA methylation, currently dominates the literature. A second mechanism, histone modification, is likely important to ecologically relevant phenotypes and thus warrants investigation, especially because molecular interplay between methylation and histone acetylation can strongly affect gene expression. There are a limited number of histone acetylation studies on non-model organisms, yet those that exist show that it can impact gene expression and phenotypic plasticity. Wild birds provide an excellent system to investigate histone acetylation, as free-living individuals must rapidly adjust to environmental change. Here, we screen …

Dna Methylation Among Chestnut-Crowned Babblers, Caddie E. Nguyen
Honors College Theses
Many Australian birds, including chestnut-crowned babblers, commonly use cooperative breeding. In these species, individuals may delay or refuse dispersal to provide care to the offspring of the others instead of producing their own. This system challenges natural selection evolution and postulates that reproductively advantage genes will be more favorable. One possibility that contributes to chestnut-crowned babblers’ dispersal behavior is the epigenetic modifications interacting between the genome and the environment during development. Chestnut-crowned babblers (Pomatostomus ruficeps) are usually found in arid and semi-arid zones, which are varied and poor-conditioned. In the undesired conditions, helpers are needed for breeding to occur …
