Biophysical factors driving the distribution and abundance of redband/steelhead trout (Oncorhynchus mykiss gairdneri) in the South Fork John Day River Basin, Oregon, USA

Creator:: Madriñán, Luis Francisco
Abstract:: The overall goal of this study was to identify multiple scales of habitat use and habitat electivity by redband/steelhead trout and define the limiting factors affecting the distribution patterns of this species during summer flows. The main objective in chapter 2 was to identify the most important habitat associations that...

How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

The evolution of Mexican forest policy and its influence upon forest resources

Creator:: Crocker, Marvin D., 1934-
Abstract:: During the Colonial Period, in Mexico there was no rational forest development policy and, as a result, forest resources were squandered and to a considerable extent destroyed. During the Nineteenth Century, a rational forest policy began to be promoted, but in the end, it was translated into a policy of...

The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...

Probabilistic models for quality control in environmental sensor networks

Creator:: Dereszynski, Ethan W.
Abstract:: Networks of distributed, remote sensors are providing ecological scientists with a view of our environment that is unprecedented in detail. However, these networks are subject to harsh conditions, which lead to malfunctions in individual sensors and failures in network communications. This behavior manifests as corrupt or missing measurements in the...

Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

Creator:: Urbina Gonzalez, Jenny Cecilia
Abstract:: This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Depth estimation and frontal imaging via X-band marine radar

Creator:: Honegger, David Andrew
Abstract:: This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

Fluid-structure interaction analysis with the particle finite element method

Creator:: Zhu, Minjie
Abstract:: To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

Jointed goatgrass (Aegilops cylindrica Host) genetic diversity and hybridization with wheat (Triticum aestivum L.)

Creator:: Gandhi, Harish Tulshiramji
Abstract:: Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an agriculturally important species both as a weed and as a genetic resource for wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to better understand the evolution of this species, the diversity of Ae. cylindrica was evaluated along with its progenitors,...
