Increased prolactin (PRL) secretion by the anterior pituitary gland is responsible for expression of incubation behavior that results in ovarian regression and loss of egg production in turkey breeder hens. A cellular basis for the heightened PRL secretion in the turkey hen has …
This research on wild orangutans (Pongo pygmaeus pygmaeus) in Gunung Palung National Park, West Kalimantan, Indonesia, on the island of Borneo, investigated how fluctuations in fruit availability affect orangutan nutritional intake, energetics and ultimately reproductive functio…
Evolutionary theory predicts that male parental care in mammals will be rare. However, siamang males are reported to provide extensive care for infants. Infant care patterns in wild siamangs have not been described in detail, and the function of male care is unknown. This disser…
This dissertation reads Anglophone literature from the U.S. and India to formulate the concept of "eugenic feminism." Eugenic feminism is a self-purifying and -perfecting rhetoric that works to create a feminist subject free of race. In so doing, eugenic feminism comes to depend…
Reproductive success can be highly variable within wild turkey (Meleagris gallopavo silvestris) populations, and success in some regions appears to be primarily associated with annual fluctuations in nest or poult survival. Identification of factors causing variation in these pa…
A great number of studies have identified strong genetic differences between sympatric anadromous and resident populations of Salmonidae. However, Arctic char (Salvelinus alpinus) migratory phenotypes in the Nettilling Lake and Amadjuak River ecosystem in Nunavut, Canada have no…
