Variations In Phenotypic Plasticity And Fluctuating Asymmetry Of Leaf Morphology Of Three Quercus (Oak) Species In Response To Environmental Factors, Joseph Kusi

Electronic Theses and Dissertations

Leaf morphology of Quercus (oak) species is highly variable and complicated confounded with phenotypic plasticity and fluctuating asymmetry (FA). However, the study of variation is mostly limited to leaf morphology. This study was extended to plasticity and FA variations in Q. alba (white oak), Q. palustris (pin oak), and Q. velutina (black oak). It was hypothesized that light exposure, individual trees, leaf position, and other leaf traits will influence variation in these species. Leaves were sampled from trees of these species and their morphological traits were measured. Absolute asymmetry of leaf width and area were determined and plasticity of each …

Fresh Squeezed: The Dilemma Of Local Food Production Along Colorado's Front Range Urban Corridor, Amanda Jessie Weaver

Electronic Theses and Dissertations

Today, the Front Range Urban Corridor of Colorado is one example from the urban/agricultural battlefield. The history of food production and urbanization in this area is similar to many regions throughout the western United States.

'Everything Looks Different Up Close': Perception In Margaret Atwood's Oryx And Crake And The Year Of The Flood, Jennifer Leora Nessel Cassidy

Electronic Theses and Dissertations

In the first two books of her MaddAdam series (a projected trilogy), Margaret Atwood explores a series of events from three very different perspectives. A close reading of the two texts suggests that the specific focalizers chosen, and their very different ways of perceiving the world around them, are central issues in the novels. In Oryx and Crake, Atwood establishes the apocalypse as a problem of dystopian vision through the book's deeply flawed focalizer. In The Year of the Flood two alternative visions are offered in order to rehabilitate the perceptual problems of the first text. In the three …

Differential Expressions Of Nodal-Signal Transducers And Global Transcriptional Repression Commit Vegetal Cells In Eleutherodactylus Coqui To Form Nutritional Endoderm, Suman Chatterjee

Electronic Theses and Dissertations

The vegetal core cells of a Xenopus laevis embryo commit to mesendoderm via the Nodal-signaling pathway. In Eleutherodactylus coqui, a direct developing frog, mesendoderm is specified at the marginal zone of the early gastrulae and vegetal core cells transform into nutritional endoderm. It is a novel tissue consisting of transient, yolk rich cells that provide nutrition, but do not differentiate into adult tissues. We hypothesized that a disruption of Nodal-signaling is responsible for committing vegetal core cells to nutritional endoderm. I report a dual regulation involved in the generation of nutritional endoderm. First, differential expression of Nodal-signaling components like Smad2 …

Impacts Of Land Cover Changes On Ecosystem Services Delivery In The Black Hills Ecoregion From 1950 To 2010, Suzanne Cotillon

Electronic Theses and Dissertations

Environmental degradation generated by land use choices and human activities is the first driver of change in the provision of ecosystem goods and services. One of the challenges in ecosystem services research is to evaluate the contribution of each land cover unit to ecosystem services delivery while considering multiple services. In this thesis, I develop a framework to assess the capacity of many land covers to independently produce ecosystem services (i.e., potential production) and the capacity of the whole landscape to deliver multiple services to the population (i.e., potential supply). In the first part, this methodology is used to report …

The Crack Room: A Study Of Therapeutic Techniques And The Response To Drug-Related Cues, Hallie Smith Carlton

Electronic Theses and Dissertations

Drug addiction is a disorder frequently associated with chronic relapse. An individual's return to use is a fairly prevalent topic in the literature, but receiving less examination is the significance of drug-related stimuli as they apply to drug-seeking behaviors. It cannot be ignored that triggers and cues are a prominent feature in everyday life. Although many non-addicted people fail to become aroused by common stimuli, individuals who are addicted to alcohol and other drugs see depictions of use in unlikely places. In the eyes of an addict, a light bulb may prompt a desire to smoke methamphetamines, and a simple …

Habitat Use And Feeding Ecology Of Delphinids Inferred From Stable Isotopes And Fatty Acid Signatures, Nicole Browning

Electronic Theses and Dissertations

Prey availability, directly or indirectly, affects all aspects of a predator’s life history and is a primary factor influencing habitat selection and movements. This is especially true for delphinid species where it has been documented that the behaviors and movements of dolphins are strongly influenced by food availability. Unfortunately, the feeding ecology and habitat use patterns of many of these species are poorly understood. Many methodologies that have been employed to explore these facets of dolphin ecology have limitations and constraints or are logistically infeasible. Stable isotope and fatty acid signature analyses have been used extensively on a wide variety …
