Abundance Of Spiders And Insect Predators On Grapes In Central California, Michael J. Costello, Kent M. Daane
Abundance Of Spiders And Insect Predators On Grapes In Central California, Michael J. Costello, Kent M. Daane
Horticulture and Crop Science
We compared the abundance of spiders and predaceous insects in five central California vineyards. Spiders constituted 98.1% of all predators collected. More than 90% of all spiders collected were from eight species of spiders, representing six families. Two theridiids (Theridion dilutum and T. melanurum) were the most abundant, followed by a miturgid (Cheiracanthium inclusum) and an agelinid (Hololena nedra). Predaceous insects comprised 1.6% of all predators collected, and were represented by six genera in five families. Nabis americoferis (Heteroptera, Nabidae) was the most common predaceous insect, with its densities highest late in the growing …

Food Choices For The 21st Century, Louise Berner, Nancy Childs, Constance Geiger, Carl Keen, Janet King, Janet Mcdonald, Sanford Miller, Suzanne Murphy, Harold Schmitz, Anne Shaw, Phil Tong, Connie Weaver
Dairy Science
In December 1997, a coalition of health professional with a wide range of expertise in science, government, education, marketing and communications, convened to discuss the challenges and implications of food choices for the 21st Century. Taking the newly published Dietary Reference Intakes (DRIs) as a framework and starting point, the members of the coalition explored how health professionals can individualize dietary recommendation to help guide people in their food choices.

Response To Dietary Dilution In An Omnivorous Freshwater Turtle: Implications For Ontogenetic Dietary Shifts, Shannon J. Mccauley, Karen A. Bjorndal
Response To Dietary Dilution In An Omnivorous Freshwater Turtle: Implications For Ontogenetic Dietary Shifts, Shannon J. Mccauley, Karen A. Bjorndal
Biological Sciences
Several species of freshwater turtles in the family Emydidae undergo an ontogenetic dietary shift; as juvenile turtles mature, they change from a primarily carnivorous to a primarily herbivorous diet. It has been hypothesized that this shift results from an unfavorable ratio of gut capacity to metabolic rate that prevents small reptiles from processing adequate volumes of plant material to meet their energetic demands. Effects of dietary dilution on intake were evaluated in two size classes of red-eared sliders (Trachemys scripta elegans) to test whether small reptiles have a lower capacity to compensate for low-quality diets through increased intake …
Nitrogen Utilization In Creeping Bentgrass, Y. Kuo, T. W. Fermanian, David J. Wehner
Nitrogen Utilization In Creeping Bentgrass, Y. Kuo, T. W. Fermanian, David J. Wehner
Office of the Dean (CAFES) Scholarship
N utilization, including plant dry weight (DW) production, total N and nitrate N (NO3-N) content accumulation, N utilization efficiency (NUE), root absorption efficiency (RAE), reduced N accumulation, and nitrate assimilation capacity (NAC) were determined for creeping bentgrass cultivars grown in hydroponic culture. Possible mechanisms affecting N utilization including nitrate reductase activity (NRA) and root morphology were also examined. Four cultivars, selected from an initial screening of creeping bentgrasses were grown under both low and high levels of N in a flowing solution culture system. The relationship between NUE and plant growth for two different creeping bentgrass cultivars was …
Production Of Biogenic Mn Oxides By Leptothrix Discophora Ss-1 In A Chemically Defined Growth Medium And Evaluation Of Their Pb Adsorption Characteristics, Yarrow M. Nelson, Leonard W. Lion, William C. Ghiorse, Michael L. Shuler
Production Of Biogenic Mn Oxides By Leptothrix Discophora Ss-1 In A Chemically Defined Growth Medium And Evaluation Of Their Pb Adsorption Characteristics, Yarrow M. Nelson, Leonard W. Lion, William C. Ghiorse, Michael L. Shuler
Civil and Environmental Engineering
Biogenic Mn oxides were produced by the bacterium Leptothrix discophora SS-1 (= ATCC 3182) in a chemically defined mineral salts medium, and the Pb binding and specific surface area of these oxides were characterized. Growth of SS-1 in the defined medium with pyruvate as a carbon and energy source required the addition of vitamin B12. Complete oxidation of Mn(II) within 60 h required the addition of ≥0.1 μM FeSO4. Pb adsorption isotherms were determined for the biogenic Mn oxides (and associated cells with their extracellular polymer) and compared to the Pb adsorption isotherms of cells and …
Effects Of Discontinuing Coffee Intake On Iron Deficient Guatemalan Toddlers' Cognitive Development And Sleep, Patrice L. Engle, T. Vasdias, I. Howard, M.E. Romero-Abal, J. Quan De Serrano, J. Bulux, N. W. Solomons, K. G. Dewey

Psychology and Child Development
Coffee is commonly given daily to toddlers in Guatemala. Possible negative effects of coffee ingestion on cognitive development and sleep patterns were assessed in 132 children 12–24 months of age who had received coffee for >2 months and were iron deficient on at least one indicator. Children were stratified by initial hemoglobin (A=anemic, Hgb

Dietary Intake And Gallbladder Disease: A Review, Marilyn Tseng, James E. Everhart, Robert S. Sandler
Dietary Intake And Gallbladder Disease: A Review, Marilyn Tseng, James E. Everhart, Robert S. Sandler
Kinesiology and Public Health
Objective: Dietary intake has long been looked upon as a potentially modifiable risk factor for gallbladder disease (GBD), here defined as either having gallstones or having had surgery for gallstones. This paper reviews the epidemiological evidence for an association between dietary intake and GBD, focusing on six dietary factors that have received the most attention in studies in this area: energy intake, fatty acids, cholesterol, carbohydrates and fibre, calcium and alcohol. The objectives of this review are to evaluate the potential usefulness of altering the diet to prevent GBD and to consider future research in this area. Design: We reviewed …

Interaction Of Blood Pressure And Ldl Cholesterol In Early Atherosclerosis. The Los Angeles Atherosclerosis Study, Ping Sun, Kathleen M. Dwyer, Noel Bairey Merz, Wei Sun, Lisa M. Nicholson, Cheryl Nordstrom, James H. Dwyer
Food Science and Nutrition
Background. The response to injury model of atherosclerosis has been investigated in animal models but not in epidemiologic studies. Relations between LDL cholesterol and carotid intima-media thickness (IMT) within levels of SBP provide a test of this model. Methods. Data are from a longitudinal study of 573 randomly sampled asymptomatic employees of a large company aged 40-60 years. IMT and change in IMT over 18 months (8IMT) were determined sonographically in the common carotid artery. 497 subjects were available for cross-sectional analysis. To investigate interactive effects of SBP and serum LDL on IMT, linear slopes (j±SE in mm/mmol/L) of IMT …

Fertigation Basics, Charles M. Burt
Fertigation Basics, Charles M. Burt
BioResource and Agricultural Engineering
Fertigation is widely practiced with drip irrigation, yet remains very unsophisticated. Major areas which need improvement are (i) making certain the irrigation system applies water with a high DU (uniformity), (ii) using proper injection pumps and protection hardware, (iii) recognizing that chemicals can interact with each other and with water to form precipitates which will clog emitters, (iv) understanding of nutrient ratios in plants and soil, (v) recognizing that nitrogen fertilization requires attention to the type of nitrogen, and (vi) developing programs for spoon-feeding chemicals. This paper covers the first 4 topics, plus discusses some specific fertilizers.

Model For Trace Metal Exposure In Filter-Feeding Flamingos At Alkaline Rift Valley Lake, Kenya, Yarrow M. Nelson, Ramesh J. Thampy, Gideon K. Motelin, Jackson A. Raini, Cynthia J. Disante, Leonard W. Lion
Model For Trace Metal Exposure In Filter-Feeding Flamingos At Alkaline Rift Valley Lake, Kenya, Yarrow M. Nelson, Ramesh J. Thampy, Gideon K. Motelin, Jackson A. Raini, Cynthia J. Disante, Leonard W. Lion
Civil and Environmental Engineering
Abstract—Toxic trace metals have been implicated as a potential cause of recent flamingo kills at Lake Nakuru, Kenya. Chromium (Cr), copper (Cu), lead (Pb), and zinc (Zn) have accumulated in the lake sediments as a result of unregulated discharges and because this alkaline lake has no natural outlet. Lesser flamingos (Phoeniconaias minor) at Lake Nakuru feed predominantly on the cyanobacterium Spirulina platensis, and because of their filter-feeding mechanism, they are susceptible to exposure to particle-bound metals. Trace metal adsorption isotherms to lake sediments and S. platensis were obtained under simulated lake conditions, and a mathematical model was …
