Cuphea laminuligera Koehne and Cuphea lutea Rose in Koehne are
undomesticated species having potential as oilseed crops. Genetic
markers and mating systems have not been described for these
species. Our objectives were to survey these species for allozyme
variation, analyze the segregation and linkage of polymorphic loci,
estimate autofertility and...
This thesis describes a case study of the effects of five systems
of grazing on watershed values in a deteriorated riparian area. Soil
infiltration, bulk density and penetrability, streambank edge movement
and coliform bacteria were monitored for seven years along a stream
in the Blue Mountains of northeastern Oregon. For...
Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...
The first part of this thesis describes a study of the
characteristics of oxidation of a 1:2 iron(III):thiolate system in
methanolic solution and in water. This system was investigated as a
potential analog for the cysteine- and cysteamine-dioxygenase catalyzed
0₂-oxidation of cysteine and cysteamine, respectively, to the
corresponding sulfinic acids....
Paired 30-day trials were conducted to evaluate
Agropyron spicatum germination when treated with two
concentrations of throughfall leachates from western
juniper slash in two stages of decomposition. Data from
a second pair of 49-day greenhouse trials were analyzed
to evaluate emergence and growth of Aqropyron spicatum,
Oryzopsis hymenoides, and Poa...
A sample of 398 rural and urban homemakers who participate in the Oregon State University Extension Home Economics study group program were surveyed to identify their perceptions of quality in fresh fish purchased for home use. The need for quality indicators on labels of fresh fish, and household practices pertaining...
In this study I assessed the potentials of selected, established perennial grasses to maintain site occupancy in the foothills ecosystem of the Rogue River Valley of southwest Oregon which is currently dominated by a variety of annual plants. The first evaluation compared growth curves of the perennial grasses and contrasted...
Several aspects of cattle grazing behavior and distribution
were studied on mountain rangeland dominated by ponderosa pine-
Douglas fir, mixed conifer, and white fir forest communities in
northeastern Oregon.
The association between upland distribution, determined by
forage utilization and by direct cattle observation, and several
habitat factors was studied through...
Little is known about cactus nutrients, their
proportions in different species and the variability of
these proportions with season. In the scant literature
available on Opuntia species, no systematic survey has
been published to document and compare the nutritional
qualities of different species. Also, no studies have
been done to...
