The fruits and seeds of the Rancho La Brea Pleistocene deposits

Creator:: Templeton, Bonnie Carolyn
Abstract:: More than 4,000 specimens of fruits and seeds were extracted from the matrix removed from inside the skulls of sabre-tooth cats excavated from various pits in the Rancho La Brea deposits. Of this number, spproximately 1,445 specimens are involved in this study. Many comparisons with modern fruits and seeds made...

Relationships of exotic species and wildfire to the threatened plant Silene spaldingii

Creator:: Menke, Carolyn A.
Abstract:: In the canyon grasslands of Garden Creek Ranch Preserve in Idaho, where the threatened plant Silene spaldingii occurs and invasion by the exotic species Centaurea solstitialis and Bromus tectorum is proceeding rapidly, I examined environmental and community patterns of site invasion, and evaluated the apparent influence of invasion on Silene...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...

The biology and control of Phytophthora root and stem rot of apple rootstocks from stool beds

Creator:: Tidball, Carolyn Jean
Abstract:: The present studies were conducted to better understand the etiology, epidemiology and potential control of the Phytophthora stem root rot as it occurs in apple stool beds. Symptoms of Phytophthora root and stem rot occurred as early as May and continued to develop throughout the growing season. Sunken brown-black lesions...

Mediation of conifer root growth by mycorrhizal fungi and plant growth regulators

Creator:: Scagel, Carolyn F.
Abstract:: Many mycorrhizosphere microorganisms can produce plant growth regulating compounds in vitro. Plant growth regulating compounds are known to mediate root growth and development. In reforestation practices, conifer tree seedling growth and survival are linked to rapid root growth and development after outplanting. Multifactorial experiments were conducted to document variations in...

Environmental Factors Affecting Phytophthora Root Rot of Rhododendron

Creator:: Mestas, Angie
Abstract:: Phytophthora root rot decreases availability and quality of rhododendrons produced in the USA. Symptoms of Phytophthora root rot include root necrosis, leaf chlorosis, stunting, and permanent wilt. The purpose of this thesis was to better understand the impact of root damage, soil moisture, nitrogen fertilizer application, and pathogen species on...

Maize Metabolic Network Construction and Transcriptome Analysis

Creator:: Monaco, Marcela K., Sen, Taner Z., Dharmawardhana, Palitha D., Ren, Liya, Schaeffer, Mary, Naithani, Sushma, Amarasinghe, Vindhya, Thomason, Jim, Harper, Lisa, Gardiner, Jack, Cannon, Ethalinda K.S., Lawrence, Carolyn J., Ware, Doreen, and Jaiswal, Pankaj
Abstract:: A framework for understanding the synthesis and catalysis of metabolites and other biochemicals by proteins is crucial for unraveling the physiology of cells. To create such a framework for Zea mays L. subsp. mays (maize), we developed MaizeCyc, a metabolic network of enzyme catalysts, proteins, carbohydrates, lipids, amino acids, secondary...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...

Reevaluation of systematic relationships in Triticum L. and Aegilops L. based on comparative morphological and anatomical investigations of dispersal mechanisms

Creator:: Morrison, Laura A.
Abstract:: Comparative morphological and anatomical studies of the dispersal mechanisms characterizing the wheat complex (Triticum L. and Aegilops L.) have documented patterns of adaptive radiation which may have significance for evolutionary relationships. These patterns, which form an array of diverse types of diaspores among the diploid taxa, appear conceptually to have...

Development of Computational, Visualization, and Molecular Tools for Fungal and Oomycete Community Ecology

Creator:: Foster, Zachary Stephen Longiaru
Abstract:: Oomycetes are an important group of organisms with a variety of ecological roles similar to fungi. Although many are well-studied plant pathogens known for their devastating effects on agricultural systems, most are little-studied saprobes and parasites of plants and animals in nearly every ecosystem on earth. The advent of affordable...
