This thesis consists of four chapters. Literature is
reviewed in Chapter 1. Chapter 2 describes an addition
series experiment to determine the influence of species
density and proportion on vegetative and reproductive yield
of spring wheat and Lolium multiflorum. Chapter 3 consists
of a growth analysis experiment to determine whether...
A fossil-calibrated phylogenetic framework based on exemplars from each of the four taxonomic sections within Pinus was created using multiple nuclear and chloroplast loci. Calibration at the well-defined subgeneric split within Pinus with either fossil leaves and cones (ca. 45 million years ago) or fossil wood (ca. 85 million years...
In addition to its longstanding recognition as an influential evolutionary process, interspecific hybridization is increasingly regarded as a potential threat to the genetic integrity and survival of rare plant species, manifested through gamete wasting, increased pest and disease pressures, outbreeding depression, competitive exclusion, and genetic assimilation. Alternatively, hybridization has also...
The central goal of this study was to assess Venezuelan parent attitudes toward specific areas of parent-child
relationships such as child creativity, child play,
parental sense of frustration in childrearing, the amount
of parental control exercised over their children, and
parents' perception of themselves as teachers of their
own children....
Recent advances in DNA vaccine technology has brought about a promising strategy for the control of viruses that contain surface membrane glycoproteins. This type of vaccine involves the intramuscular injection of a bacterial plasmid containing a gene encoding a viral protein. The strategy uses eukaryotic processing of the protein as...
The Mx protein family of rainbow trout (Oncorhynchus mykiss) was characterized at the molecular level. With primers derived from a partial sequence of Perch (Perca fluviatis) Mx genomic DNA, a partial rainbow trout Mx genomic DNA sequence was obtained by polymerase chain reaction (PCR) amplification. All salmonid fish investigated contained...
The purpose of this study was to assess the usage of distance education in undergraduate dietetics programs. Additionally, the possibility of obtaining an undergraduate degree in dietetics via distance education was examined. The population receiving the survey research was all directors (279) of Commission on Accreditation for Dietetics Education (CADE)...
Several systems were examined for the production and delivery of recombinant vaccines for fish. C. crescentus was employed to produce a fragment of the IHNV glycoprotein. When administered by injection to 0.5 gram rainbow trout (Oncorhynchus mykiss), one of the fusion proteins (184 amino acids of the IHNV glycoprotein fused...
