This map depicts both the bedrock geology and the general ages and distribution of Late Tertiary and Quaternary deposits and geomorphic surfaces in the northern part of the lower Verde River Valley, in Maricopa County. The map area includes portions of the Fort McDowell and McDowell Peak 7.5' U.S.G.S. topographic quadrangles (Figure 1). The region studied encompasses the region between the northern end of the McDowell Mountains on the west to about one mile east of the Verde River on the east. Mapping of the surficial deposits was based both on field observations and interpretation of black-and-white, 1:48,000-scale aerial photographs (dated 12-9-90) purchased from the Arizona Department of Transportation Photogrammetry and Mapping Division.Additional Links

A Tale of Two 'omes: Comparative Genomics and Important Genes in Specialized TissuesAnalysis of complex traits like plant specialized metabolism is a difficult task in non-model systems as plant specialized metabolism is controlled by a number of factors such as environment, genotype, age, and tissue. To help address this problem, we have taken a bioinformatic approach that involves sequencing select tissues that are enrichedfor the biosynthesis of specialized metabolites. Using this approach, we have sequenced multiple tissues from a variety of species and compared them against one another. This comparative approach has allowed us to identify some of the genes responsible for the biochemical differences in and between species as well as genes that may be involved in control of specialized tissue development or metabolism. This dissertation begins with a brief introduction of plant metabolism, and pays special attention to historical and present views of plant metabolism, the importance of specialized metabolism, its evolution, and why it is advantageous to study specialized metabolism from specialized tissues like glandular trichomes and rhizomes. To this end, I detail our production and comparisons of glandular trichomes of several Solanum species using next-generation 454 sequencing. I also extensively review the underground stems, or rhizomes, of Viridiplantae. Discussions of our production and comparison of rhizome EST libraries from Zingiber officinale, Curcuma longa, and several Sorghum species are also made. My efforts to lay the groundwork that will hopefully permit functional analysis of interesting genes identified through our sequence comparisons of glandular trichome or rhizome EST libraries, in non-model systems are also discussed.

A stock pond simulation model for chaparral watersheds in ArizonaA previously developed methodology to model the hydrologic performance of stock ponds is modified and tested using data from Arizona chaparral watersheds. The modified method uses stochastic computer models to generate time series' of daily precipitation and temperatures, then transforms this synthetic data into daily streamflow using a soil moisture accounting model. The streamflow model, called a Generalized Streamflow Simulation System, is used to simulate the long "baseflow" recessions typical of chaparral watersheds. Generated streamflow is routed through a set of standard stock ponds to yield statistics and probability distributions for the following annual pond performance criteria: runoff retention, spillage, and pond dry days. A case study of pond performance on a chaparral watershed is performed using the calibrated simulation model. Simulation results are discussed in the context of previous case studies for other areas of Arizona. Simulation results, computer program listings, and sample outputs are included in the report.
