Hydrate Ridge is an accretionary thrust ridge located on the lower slope of the central Cascadia convergent margin. Structural mapping based on two-dimensional and three-dimensional multichannel seismic reflection profiles and gridded bathymetry coupled with deep-towed sidescan sonar data and Ocean Drilling Program (ODP) biostratigraphy suggests that seafloor fluid venting patterns...
During Ocean Drilling Program Leg 204, 80 in situ measurements of
subseafloor temperature were made; 68 of these showed good frictional
pulses on insertion and extraction from the seafloor and were used to
constrain the subsurface temperature. Considering uncertainties from
various sources, uncertainties in the in situ temperatures are estimated...
This paper presents a seismic sequence and structural analysis of a high-resolution three-dimensional seismic reflection survey that was acquired in June 2000 in preparation for Ocean Drilling Program (ODP) Leg 204. The seismic data were correlated with coring and logging results from nine sites drilled in 2002 during Leg 204....
Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly...
1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...
In an increasing sedentary society, it is becoming even more important to
encourage adolescent girls to participate and value physical activity. This
document provides a study grounded in scholarly research exploring issues of
importance to the promotion and implementation of programs relevant to
motivating girls to be physically active, specifically...
Mycorrhizal fungi are important in food production of arid lands.
The desert truffles not only form a symbiotic association with range
plants but also form fruiting bodies which are both prized as food and
nutritious. The taxonomy and ecology of two genera of desert truffles
are treated in this thesis....
Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...
The several thousand fungi known to form ectomycorrhizae have co-evolved with their host plants and have developed impressive physiological and ecological diversity. Exploration of some relationships of enzyme activities and phytohormone production of selected ectomycorrhizal fungi to distribution and tree hosts is reported in this thesis. The data have particular...
