Semi-volatile organic compounds and developing organisms : accumulation in California mountain tadpoles in the field and fish embryo exposures in the laboratory

Creator:: Stanley, Kerri A.
Abstract:: The atmospheric transport and deposition of semi-volatile organic compounds (SOCs), including current and historic use pesticides, polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), to mountain ecosystems may result in the exposure of tadpoles to these SOCs. This exposure has been implicated in amphibian population declines in California. Tadpoles encounter...

The effects of atrazine on growth of flax (Linum usitatissimum L.) plants and on yield, chemical composition and germination of flax seeds

Creator:: Locatelli, Eduardo Atilio
Abstract:: Reports of previous research indicated a stimulatory effect of triazine herbicides on growth, yield and protein content of plants and seeds of various species. Studies were conducted in the greenhouse, laboratory and field to investigate the effects of atrazine (2-chloro-4-ethylamino-6-a sopropylarnino- s-triazine) on growth, yield, seed composition, and seed germination...

Individual and demographic responses of the gray-tailed Vole (Microtus canicaudus) to an endocrine disruptor

Creator:: Caslin, Tracie M.
Abstract:: In an experimental field study, populations of gray-tailed voles (Microtus canicaudus) were exposed to a commercial formulation of vinclozolin, a fungicide effective for disease control on ornamental plants, turf grasses, and fruits and vegetables. Vinclozolin has been shown in laboratory experiments to behave as an androgen antagonist, impairing the reproductive...
Resource Type:: Masters Thesis
Full Text:: with one application of Curalan® fungicide, Vinclozolin had only a slight effect on the reproductive

Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

Full Text:: when exposed directly to UVB. My research emphasizes that the main effect of UVB on an organism may

Developmental axial skeletal deformities : baseline study with a zebrafish model

Creator:: Harden, Jon M.
Abstract:: The aim of this study was to assess sensitivity of early life stage zebrafish to cadmium (Cd). Embryos and larva were exposed to Cd before the formation of skeletal elements. Exposure times were selected to determine whether Cd perturbed developmental processes that lead to skeletal deformities, and to characterize the...
Resource Type:: Masters Thesis
