The intention of this honors thesis was to define the boundaries of the basins responsible for feeding sedimentary materials to the core sites taken for the 2007 OSU Sumatra Cruise. These boundaries were defined with the specific use in mind of tracking potential sources of material that would likely be...
In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...
Two types of exogenous mortality factors, density-independent and density-dependent, were identified for the black vine weevil, Otiorhynchus sulcatus Fab., developing on container grown rhododendrons. The addition of the insecticide acephate, (O.S.- Dimethyl acetylphosphoramidothioate, Orthene®)75S) to the rhizosphere of rhododendrons in which larval O. sulcatus develop was categorized as a density-independent...
The antimutagenic potency of wheat grain and berry extracts was studied in vitro against several heterocyclic amines (HCAs) using the Salmonella mutagenicity assay and the anticarcinogencity of wheat grain was studied in vivo using the rat colonic aberrant crypt focus assay. Wheat bran, which binds HCAs in vitro, as well...
At a time of rapid global change, a socio-ecological system (SES) approach can provide a framework through which to quantify and communicate the risks and uncertainties of coupled human-natural systems. Islands, and tropical coral reef islands in particular, can be excellent models for SES research since they may be considered...

Five experiments were conducted to evaluate tree forage as a feedstuff for small livestock, using the foliage of black locust (Robinia pseudoacacia) and hybrid poplar (Populus spp.). In the first trial, rabbits were fed diets containing 40% alfalfa (control), and 10%, 20% and 40% poplar leaves (PL) from untrimmed or...
The carboxylesterases of three species of diptera, the flesh
fly (Sarcophaga bullata, Park.), the black blow fly (Phormia regina,
Meig.), and the house fly (Musca domestica, L.) were compared in relation
to hydrolytic activity against three substrates, response to
inhibition and induction, isozyme composition, and age-dependent
variation in activity. Similar...
