The following are abstracts from projects funded in 2001 to the present.

Animal Science

  • This project will characterize the expression pattern of genes regulating food intake between congenic mouse strains prone to leanness and obesity.

Entomology

  • Using forensic DNA fingerprinting techniques, I will investigate the minimum threshold size of mosquito bloodmeals that allows for detection of complete profiles in seven loci of human DNA. DNA profiles will be compared to bloodmeal weight to determine if there is a positive correlation between the amount of blood imbibed and the success of amplification.
  • I will investigate the relationship between two closely related species of seed-harvesting ants in the genus Pheidole. Based on field collections at selected sites in California, Nevada and Oregon, I will assess the differences in ecology, behavior and morphology. This will be complemented by genetic analysis of the same collections, with the ultimate goal of revealing species and population level patterns.
  • Production of a set of ceramic art tiles, illustrating various scientific concepts about insects, an art and science collaborative approach to research and product.

Food Science & Technology

  • The purpose of this project is to study moisture redistribution in a food system by MRI. MRI has been used for monitoring moisture migration between foods and environment, but not for moisture redistribution within a food system. Using MRI, moisture distribution in food, SnackWell's devil's food cake in particular, stored in various lengths of time will be monitored. This will provide us new information about the mechanism of moisture transportation within food systems. Moisture redistribution is a major contributor to product quality loss.
  • This project will identify and quantify various carotenoids in yeast species from the Phaff Yeast Collection.

Human & Community Development

  • Replicate one study, plus examine two aspects of delayed versus "normal" preschoolers' fantasy play: (1) quality, (2) amount, origination, and type according to playmates' developmental statuses.
  • An ethnography of a Zambian wheelchair shop and its reliance on a San Francisco design firm. Asking, "Why doesn't the shop try the innovations that its own workers suggest?"

Land, Air & Water Resources

  • I will study whether in the illumination of nitrate will lead to the oxidation of bromide in seawater to produce reactive gaseous bromine. In order to gain some insight into mechanism for this reaction and how it is affected by varying environmental conditions, I will study the dependence of temperature, initial bromide and chloride concentrations and time on the reaction rate.
  • I will examine the spatial and temporal variation of temperature, carbon dioxide evolution, C:N ratio, pH, and redox potential (Eh) for three composting methods. I am proposing that a tarped passively aerated composting method will be an efficient low in-put alternative to the traditional turned method of composting.

Landscape Architecture

  • A garden design for an Elementary School will be developed. The ultimate goal is to complete a Master Plan that may be implemented over a period of time, as funding becomes available. The Master Plan will be designed using community participation methods, which involves obtaining input from the faculty, children and the community. The student population and community are ethnically diverse, with many language differences.
  • For my senior project in the landscape Architecture Department, I will design a wildlife park for bears and other native wildlife in Juneau, Alaska. I will incorporate tourism, educational programs, and wildlife habitat requirements into the final park design.
  • Most people in the profession of landscape design create and apply new theories of sustainability but rarely have time to do case studies or post occupancy evaluations of how successful their projects have actually been. In this research project I will interview successful sustainable landscape architects and designers in the SF Bay Area to identify the most successfully examples of sustainable landscape design in the SF Bay Area. I will create a typology of these projects, and the five sites that are named most frequently will be the subjects for case studies. I will interview the residents and designers to find out how successful they think the project has been over time according to a set of seven variables. From the findings of these case studies I will propose the best ways to implement these design ideas for best success on future projects in the Bay Area. To inform the profession about how they can make their projects more sustainable, I will make fact sheets, a map of how to get to these sites, and a checklist of the major principles of ecological design to include in projects.
  • Kids and Carrots shall create and evaluate a school garden for an underprivileged elementary school. Goals include introducing students to ecological concepts and nutritional awareness.

Nematology

Plant Pathology

  • Molecular student of A. rhizogenes K84 and its effectiveness as a biocontrol against California A. tumefaciens strains.

Plant Sciences

  • Genes that potentially have a role in abscission zone signaling in Mirabilis jalapa have been identified in Professor Michael Reid's lab. However, the lab only has partial fragments of these gene transcripts, due to the procedure used to isolate them. My job will be to use a PCR-based procedure called RACE (Rapidly Amplified cDNA Ends) to generate the complete sequence of these transcripts. Then, if time permits, I will use a Genomic Walker kit to amplify the promoter regions of the genes that, by Northern analysis, have been shown to be specific to the abscission zone region.
  • This project involves the design, planting, and care of native hedgerow in the Student Farm Market garden.
  • To understand the role of the community garden in urban & suburban neighborhoods across the USA through a comparative field study spanning 1 1/2 to 2 months.
  • The goal of the project is to identify the specific role of a class of glycoproteins called arabinogalactan proteins (AGPs), found to be abundant in the early stages of root nodule formation. The objectives include 1) testing the effects of a gradient of exogenous AGP concentration on nodulation development, and 2) to isolate and purify the AGPs found in soybean root nodules and to test the effects on nodulation when applied exogenously.

Wildlife, Fish & Conservation Biology

  • I will examine the adaptive function of coloration in Artiodactyla, for example the reasons that some species have evolved white rump patches or striped coats. I will score the presence or absence of color patterns on different parts of the body and across species and relate these to environmental variables, such as living in deserts or living in groups. To control for shared ancestry, I will apply new phylogenetic comparative methods to the data set in order to see whether the associations are an artifact of phylogeny or not. My results will use systematic and quantitative methods to show why hoofed animals have different coat colors and patterns, and whether there are single or multiple functions for these coat variations.
  • I have undertaken a study in the hopes of gathering information about the life history and adaptations of the western gray squirrel in California, particularly at Quail Ridge.
  • I intend to examine incubation behavior of Wood Ducks in relation to microclimate. I predict that the warmer the microclimate is within a nest boxes the less total time a female Wood Duck will spend on the next during incubation. I also predict that the energy cost of incubation will be lower in a warmer microclimate thereby allowing the female to lay more eggs and have a higher success rate. I will test these hypotheses by placing data loggers in nest boxes with incubating females. The data loggers will record the ambient temperature in the box and the temperature of the incubating eggs. the rise and fall of the temperature of the incubating eggs will be used to determine when a female has come onto a nest and when she has left a nest.
  • I will use stable isotope analysis to temporally analyze the tissues of organisms in the aquatic and terrestrial food webs on the Cosumnes River revealing a terrestrial insect input consumed by trout in the aquatic food web.
  • This project involves assessing the diversity and abundance of birds at the Howard Ranch. Once the bird community is sufficiently understood, surrogate species will be identified and monitored to determine the role of venal pools in the abundance of facultative and obligate grassland bird species. Method of monitoring include a combination of line transects and point counts.
  • My project will examine the genetic effects of natural fluctuation and human manipulation of wood duck populations in California. Specifically, the study will look at the degree of genetic variability in wood ducks as a function of population dynamics and nest box densities.
  • DNA microsatellite technology will be used to assess the degree of relatedness among male groups of wild turkeys (Meleagris gallopavo) within a population at Citrona Farms. Observational studies will elucidate dominance hierarchies established during the winter and early spring. Data will be applied to the questions of whether male bands are composed of siblings that display together, and whether kin selection may be integral in the reproductive behavior of this gallinaceous species.
  • In Costa Rica, Central America, I plan to determine what senses (smell, vision and echolocation) bats use to locate livestock.

Evolution & Ecology

  • This project involves the development of microsatellite markers in a species of sea anemone, Epiactis Prolifera. These markers will allow me to make further conclusions about the mating system of E. Prolifera (e.g. biparental inbreeding vs. self fertilization).
  • This project is to study the population of Western Pond Turtles, Emys marmorata, currently inhabiting the UC Davis Arboretum. E. marmorata is currently listed as a species of special concern in the state of California.

This study will use basking and hoop type traps to capture turtle live at the UC Davis Arboretum. Non-native turtles will be removed as to foster the natural growth of Emys marmorata population. If successful this project may show that this species can be viably maintained in highly modified habitats in an effort at future conservation.
  • The invasive weeds, Holcus lanatus and starthistle, can out-compete many native plant species of Northern Californian. The success of these plants may be due to chemicals exuded from the plant's roots.

The anatomy of the water conducting cells will be examined with the aid of a compound microscope to understand basic water flow at the cellular level.
  • We will construct a cohort analysis in tow temporary ponds in which pure native, pure non-native and hybrid salamanders breed during the winter each year. cohort analyses have been recorded for the previous year and show that the natives may be breeding earlier but the larval frequencies seem to be highly non-native. We will construct a hybrid index for each pond with multiple loci and test our results with the previous year to predict any patterns of breeding behavior and larval fitness.
  • I will be conducting experiments on the butterfly Junonia coenia (Common Buckeye) to determine if its physical appearance is in part controlled by photoperiod and/or temperature.

  • With this funding, I propose to locate both of these new mutagen-sensitive genes and discover the functional gene they correspond to in DNA repair. Using deficiency, recombination, and p-element mapping in Drosophila melanogaster, I will narrow the region around the mutant down to a single locus and using the sequenced, searchable Drosophila genome determine what the localized gene is and what role it may play in DNA repair. This research will assist in an ongoing search for DNA repair genes and their homologs in humans.

The newly synthesized compound will be analyzed using NMR and HPLC analysis to determine if it is identical to the enzymatically produced intermediate. This compound will also be tested as a substrate for the enzyme.
  • Meiotic recombination plays an important role in chromosome segregation. Hence, I will 1) construct an assay in yeast to monitor chromosome segregation using fluorescent reporters, 2) characterize the assay in wild type cells, and 3) apply the assay to study directed knockout mutations of meiosis-specific gene(s).

  • I will test the hypothesis that the diurnal modulation of LTP in the hippocampus is due to extrinsic signals by isolating the hippocampus from all outside signals and systematically varying the length of time of isolation before recording LTP in the hippocampus. I will compare the amplitude of LTP recorded at night against that recorded during the day. If there is a significant difference at night as compared to the day despite differences in isolation time, I will conclude that the diurnal modulation of LTP is due to changes in the amplitude of signals originating inside the hippocampus. If there is not a significant difference at night as compared to the day I will conclude that the diurnal modulation is due to changes in the amplitude of extrinsic signals.

  • I want to examine how police, demographics, and the media combine to influence the actual and perceived experiences of racial profiling by young adults in New York City. A New York Times Poll, done in January of 2000, attempts to uncover the racial tensions between minority communities and New York City police. My data will consist of this New York Times Poll along with my own analysis of newspapers and television archives. I want to accomplish three things: 1) determine the demographics of racial profiling in NYC 2) determine the rates of perceived racial profiling (those who believe it is widespread) and 3) determine if the media could be an external factor that influences perceptions of racial profiling. this project has some broader implications. for one, it could uncover generalizable demographics of racial victimization. Secondly, it could show the influence of media within community perceptions of racial tensions.
  • This research will examine the popular images of femininity, sexuality, and beauty presented to adolescent females in prom magazines compared to the actual expectations and experiences of these girls at the prom. I will use methods of "content analysis" for the prom media combined with ethnographic work (personal interviews, observation) of the girls I am studying.
  • Recent reports claim that African education is in crisis primarily due to mismanagement and a misallocation of funds. However, there are other sociocultural and historical factors involved, including the systematic exclusion of African traditions, and languages from the curricula. In 1969, A. Kondi reported resistance to formal education due to the latter sociocultural factors in his study of education in Bassar, Togo. I will build on Kondi's work through a longitudinal study designed to investigate the contemporary transformation of education in Bassar today. I will conduct household surveys and in-depth interviews with village leaders and school directors to determine if there continues to be resistance to western education in Bassar and the primary causes of this resistance. Even if no resistance is found, the results of my study will help identify the main sociocultural factors behind the educational crisis in Togo.

Human Physiology

  • The aim of this proposal is to investigate the chronic effects of estrogen on sodium, calcium, and proton accumulation during ischemia (lack of blood flow) and reperfusion (return of flow) in isolated rat hearts. Maintaining homeostasis of these ions is imperative in normal heart function. Although there has been evidence that estrogen protects the heart during ischemia, recent clinical studies have shown that estrogen replacement therapy in post-menopausal women may add more detrimental risks than benefits. This proposal aims to study the ionic mechanisms involved in estrogen's effect on myocardium during ischemia in order to explore and understand the general effects of acute and chronic treatments of estrogen.

  • In this study, we propose to investigate the effects of administering UCD 026 on the growth of brain tumor cells using intracerebral implantation of the human glioma cell line U87 in athymic rats as an experimental model. The potential tumoricidal properties of UCD 026 will be examined by initiating treatment on postimplantation day 10 and continuing treatment for 10 days. The volumes of the tumors will be determined successively using proton nuclear magnetic resonance (1H-NMR) and confirmed terminally on day 20 by sacrificing the animal and using histological staining and stereology. Tumor growth during this 10 day treatment with UCD 026 will be compared to a standard growth curve of untreated animals to determine if the drug kills tumors, has anti-proliferative activity, or does both.
  • Novel therapeutics are needed for treating human glioblastoma. This project will screen specially synthesized drugs in cell culture and the most efficacious drugs in vivo.

The following are abstracts from projects funded in 2001 to the present.

Anatomy, Physiology & Cell Biology

  • This project will investigate qualitatively and quantitatively the internalization of the 5-HT3 receptor in neurons of the myenteric plexus using in vivo models. 5-HT, short for 5-hydroxytryptamine (the chemical name for serotonin), is important in stimulating feelings of nausea and intestinal pain. the receptor may internalize under different physiological stimuli, such as a high concentration of sugars or lipids in the gut. This project aims 1) to show that the 5-HT3 receptor internalizes if a strong dose of external serotonin is given and 2) to show that internalization can also occur when serotonin is released within the body in response to an intestinal stimulus like sugar or lipid. this will be accomplished by labeling tissue samples from treated rats with fluorescent antibodies directed toward the 5-HT3 receptor and clathrin, a protein that plays a significant role in internalization of cellular membrane components.
