Evolutionary And Acclimation-Induced Variation In The Heat-Shock Responses Of Congeneric Marine Snails (Genus Tegula) From Different Thermal Habitats: Implications For Limits Of Thermotolerance And Biogeography, Lars Tomanek, George N. Somero Nov 1999

Evolutionary And Acclimation-Induced Variation In The Heat-Shock Responses Of Congeneric Marine Snails (Genus Tegula) From Different Thermal Habitats: Implications For Limits Of Thermotolerance And Biogeography, Lars Tomanek, George N. Somero

Biological Sciences

Heat stress sufficient to cause cellular damage triggers the heat-shock response, the enhanced expression of a group of molecular chaperones called heat-shock proteins (hsps). We compared the heat-shock responses of four species of marine snails of the genus Tegula that occupy thermal niches differing in absolute temperature and range of temperature. We examined the effects of short-term heat stress and thermal acclimation on the synthesis of hsps of size classes 90, 77, 70 and 38 kDa by measuring incorporation of (35)S-labeled methionine and cysteine into newly synthesized proteins in gill tissue. Temperatures at which enhanced synthesis of hsps first ...


Optical Monitoring And Forecasting Systems For Harmful Algal Blooms: Possibility Or Pipe Dream?, Mark A. Moline, Oscar Schofield, Joe Grzymski, Paul W. Bissett, Gary J. Kirkpatrick, David F. Millie, Collin S. Roesler Oct 1999

Optical Monitoring And Forecasting Systems For Harmful Algal Blooms: Possibility Or Pipe Dream?, Mark A. Moline, Oscar Schofield, Joe Grzymski, Paul W. Bissett, Gary J. Kirkpatrick, David F. Millie, Collin S. Roesler

Biological Sciences

Monitoring programs for harmful algal blooms (HABs) are currently reactive and provide little or no means for advance warning. Given this, the development of algal forecasting systems would be of great use because they could guide traditional monitoring programs and provide a proactive means for responding to HABs. Forecasting systems will require near real-time observational capabilities and hydrodynamic/biological models designed to run in the forecast mode. These observational networks must detect and forecast over ecologically relevant spatial/ temporal scales. One solution is to incorporate a multiplatform optical approach utilizing remote sensing and in situ moored technologies. Recent advances in ...


Mechanical Conditioning Of Tomato Seedlings Improves Transplant Quality Without Deleterious Effects On Field Performance, Lauren C. Garner, Thomas Björkman Sep 1999

Mechanical Conditioning Of Tomato Seedlings Improves Transplant Quality Without Deleterious Effects On Field Performance, Lauren C. Garner, Thomas Björkman

Horticulture and Crop Science

Excessive stem elongation reduces plant survival in the field and hinders mechanical transplanting. Mechanical conditioning is an effective method for reducing stem elongation during transplant production. This investigation examined the consequences of mechanical conditioning, using brushing and impedance, on subsequent field performance of tomatoes (Lycopersicon esculentum Mill.). Mechanically conditioned transplants of processing tomatoes resumed growth after transplant shock as quickly as did untreated plants, and subsequent canopy development was also equal. In 4 years of field trials, yield was not reduced by mechanical conditioning. Transplants for fresh-market tomatoes may be more sensitive to injury than those for processing tomatoes because ...


Variation And Repeatability Of Calling Behavior In Crickets Subject To A Phonotactic Parasitoid Fly, Gita R. Kolluru Sep 1999

Variation And Repeatability Of Calling Behavior In Crickets Subject To A Phonotactic Parasitoid Fly, Gita R. Kolluru

Biological Sciences

Male Teleogryllus oceanicus (Orthoptera: Gryllidae) produce a conspicuous calling song to attract females. In some populations, the song also attracts the phonotactic parasitoid fly Ormia ochracea (Diptera: Tachinidae). I examined the factors affecting calling song by characterizing the calling behavior of caged crickets from an area where the fly occurs. Calling activity (proportion of time spent calling) was repeatable and a significant predictor of female attraction. However, calling activity in the parasitized population was lower than in an unparasitized Moorea population (Orsak, 1988), suggesting a compromise between high activity to attract females and low activity to avoid flies. Calling activity ...


Makaira Sp., Cf. M. Nigricans Lacépède, 1802 (Teleostei: Perciformes: Istiophoridae) From The Late Miocene, Panama, And Its Probable Use Of The Panama Seaway, Harry L. Fierstine Sep 1999

Makaira Sp., Cf. M. Nigricans Lacépède, 1802 (Teleostei: Perciformes: Istiophoridae) From The Late Miocene, Panama, And Its Probable Use Of The Panama Seaway, Harry L. Fierstine

Biological Sciences

A nearly complete rostrum (USNM 358534) similar in morphology to the extant bluc marlin, Makaira nigricans Lacepede 1802, is identified from the GaUln Formation (late Miocene, Panama). Identification is based on comparison with a large series of Recent istiophorid species and with fossil species of the genus Makaira. The Gatlin specimen and additional examples from other fossil vertebrates provide evidence that the ancient Panama Seaway probably was a travel route between the Atlantic and Indo-Pacific for large marine vertebrates during the middle Miocene to earliest Pliocene. This is the first record of an istiophorid billfish from the Gatlin Fonnation and ...

Kinesiology

Objective: Results of previous studies on diet and gallbladder disease (GBD), defined as having gallstones or having had surgery for gallstones, have been inconsistent. This research examined patterns of food intake in Mexican Americans and their associations with GBD. Design: Cross-sectional. Subjects: The study population included 4641 Mexican Americans aged 20±74 years who participated in the 1988±94 third National Health and Nutrition Examination Survey (NHANES III). GBD was diagnosed by ultrasound. Food intake patterns were identifed by principal components analysis based on food frequency questionnaire responses. Component scores representing the level of intake of each pattern were categorized ...


Induced Changes In Solvent Structure By Phospholipid Monolayer Formation At A Liquid–Liquid Interface, R. A. Walker, D. E. Gragson, G. L. Richmond Aug 1999

Induced Changes In Solvent Structure By Phospholipid Monolayer Formation At A Liquid–Liquid Interface, R. A. Walker, D. E. Gragson, G. L. Richmond

Chemistry and Biochemistry

Vibrational sum frequency spectroscopy has been used in conjunction with dynamic surface tension measurements to study formation of a 1,2-dilauroyl-sn-phosphatidylcholine (DLPC) monolayer at a water–carbon tetrachloride interface. Surface tension measurements show that an aqueous solution of liquid crystalline phosphocholine vesicles (4.5 μM DLPC) requires several hours to form a tightly packed, fully equilibrated monolayer of DLPC monomers. Vibrational spectra of the interfacial region at different stages in the monolayer formation process indicate that the solvent structure undergoes dramatic re-organization as the monolayer forms. Initial adsorption of DLPC monomers severely disrupts the interfacial hydrogen bonding. Intensity ...


Conservation Implications Of Dietary Dilution From Debris Ingestion: Sublethal Effects In Post-Hatchling Loggerhead Sea Turtles, Shannon J. Mccauley, Karen A. Bjomdal Aug 1999

Conservation Implications Of Dietary Dilution From Debris Ingestion: Sublethal Effects In Post-Hatchling Loggerhead Sea Turtles, Shannon J. Mccauley, Karen A. Bjomdal

Biological Sciences

Ingestion of anthropogenic debris by marine species has been documented extensively; fewer studies have attempted to quantify the sublethal effects caused by debris ingestion. One potential sublethal effect is reduced nutrient gains from diets diluted by consumption of debris. Post-hatchling and juvenile loggerhead sea turtles (Caretta caretta) consume substantial quantities of debris. We evaluated the effects of dietary dilution on voluntary intake in post-hatchling loggerheads to assess their ability to compensate for the presence of inert diluents in their diet by increasing dry mass intakes to maintain nutrient gains. Mean daily intakes of dry mass did not increase significantly with ...


A Pilot Study Of Exercise Training To Reduce Trunk Fat In Adults With Hiv-Associated Fat Redistribution, Ronenn Roubenoff, Lauren Weiss, Ann Mcdermott, Tanya Heflin, Gregory J. Cloutier, Michael Wood, Sherwood Gorbach Jul 1999

A Pilot Study Of Exercise Training To Reduce Trunk Fat In Adults With Hiv-Associated Fat Redistribution, Ronenn Roubenoff, Lauren Weiss, Ann Mcdermott, Tanya Heflin, Gregory J. Cloutier, Michael Wood, Sherwood Gorbach

Kinesiology

Body fat redistribution (‘lipodystrophy’), with gain in abdominal and trunk fat, and decline in facial and limb fat, is a newly recognized problem in patients with HIV infection that has been linked to use of HIV-1 protease inhibitors. Increased abdominal fat may predispose these patients to hypertension, diabetes, and coronary artery disease. At this time no effective treatment is available. We examined whether exercise training could reduce trunk fat in men with fat redistribution.


Diversity Of Microorganisms Isolated From Amber, C. L. Greenblatt, A. Davis, B. G. Clement, Christopher Kitts, T. Cox, Raul J. Cano Jul 1999

Diversity Of Microorganisms Isolated From Amber, C. L. Greenblatt, A. Davis, B. G. Clement, Christopher Kitts, T. Cox, Raul J. Cano

Biological Sciences

Claims that organisms can be cultured from amber, if substantiated, would be significant contributions to our understanding of the evolution, tenacity, and potential spread of life. Three reports on the isolation of organisms from amber have been published. Cano and Borucki recently reported the isolation of Bacillus sphaericus and Lambert et al. have described a new species designated Staphylococcus succinus from 25–40 million year old Dominican amber. These characterized organisms were phylogenetically distant from extant relatives and the Staphylococcus sp. sufficiently far removed from other extant staphylococci to be considered a new species. Here we report the culture of ...

Reductive Dehydroxy Coupling Of 2-(Hydroxymethyl)Indenes To Prepare Ethano-Bridged Bis(2-Indenyl) Ansa-Titanocenes, Hasan Palandoken, Justin K. Wyatt, Shawn R. Hitchcock, Marilyn M. Olmstead, Michael H. Nantz May 1999

Reductive Dehydroxy Coupling Of 2-(Hydroxymethyl)Indenes To Prepare Ethano-Bridged Bis(2-Indenyl) Ansa-Titanocenes, Hasan Palandoken, Justin K. Wyatt, Shawn R. Hitchcock, Marilyn M. Olmstead, Michael H. Nantz

Chemistry and Biochemistry

New examples of ansa-titanocenes derived from 1,2-bis(2-indenyl)ethane have been prepared. The titanium-mediated reductive coupling of 2-(hydroxymethyl)indenes provided a convenient method for substrate dimerization. Alkyl substitution of the indene ring at C(3) improved the regioselectivity of the reductive coupling to provide the ethylene bis(2-indenyl)ansa-ligands in 29–62% yield.


A New Shortbilled Marlin Of The Genus Makaira, From The Yorktown Formation, (Early Pliocene), Eastern North Carolina At Lee Creek Mine, Usa, Harry L. Fierstine May 1999

A New Shortbilled Marlin Of The Genus Makaira, From The Yorktown Formation, (Early Pliocene), Eastern North Carolina At Lee Creek Mine, Usa, Harry L. Fierstine

Biological Sciences

An unusually short rostrum from the Yorktown Formation, Early Pliocene, eastern North Carolina at Lee Creek Mine, USA, is described as a new species, Makaira purdyi. The rostrum is morphologically distinct from any Recent or fossil istiophorid in the following combination of characters: (1) fused portion of premaxillae is short and stout with denticlcs covering at least the distal one-half of its dorsal surface; (2) at one-fourth bill length, the cross-section is nearly round (depth/width = 0.95). The new marlin is distinguished from the extant shortbill spearfish, Tetrapturus angustirostris, and any istiophorid with a short rostrum caused by injury.


Development And Reproduction Of A Population Of Eretmocerus Eremicus (Hymenoptera: Aphelinidae) On Bemisia Argentifolii (Homoptera: Aleyrodidae), David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring Apr 1999

Development And Reproduction Of A Population Of Eretmocerus Eremicus (Hymenoptera: Aphelinidae) On Bemisia Argentifolii (Homoptera: Aleyrodidae), David H. Headrick, Thomas S. Bellows, Jr., Thomas M. Perring

Horticulture and Crop Science

Although the aphelinid parasitoid Eretmocerus eremicus Rose & Zolnerowich is the most abundant naturally occurring parasitoid of Bemisia argentifolii Bellows & Perring in the U.S. desert southwest, its effectiveness in different cropping systems varies. Development and reproduction of a population of this parasitoid attacking B. argentifolii infesting cotton, Gossypium hirsutum L., and sweet potato, Ipomoea batatas L., were quantified and compared. Females potato; there were no significant differences of these parameters between host plant species. A preoviposition period of 0.61 d was recorded, and a maximum number of eggs laid in a day was 69 on cotton and 13 on sweet potato. The average preimaginal developmental periods for males and females on either host plant were not significantly different and averaged 22.58 d. The mean number of progeny produced on cotton was 25.4 with 51.5% of these female, whereas the mean number of progeny produced on sweet potato was 7.5 with ...


Calculation Of Population Attributable Risk For Alcohol And Breast Cancer (United States), Marilyn Tseng, Clarice R. Weinberg, David M. Umbach, Matthew P. Longnecker Apr 1999

Calculation Of Population Attributable Risk For Alcohol And Breast Cancer (United States), Marilyn Tseng, Clarice R. Weinberg, David M. Umbach, Matthew P. Longnecker

Kinesiology

Objectives: Because of increasing evidence that alcohol may be causally associated with breast cancer, we reconsider the population attributable risk (PAR) for alcohol and breast cancer for the US adult female population using an effect estimate from a meta- analysis and incorporating a revised perspective on measurement error correction. Methods: To estimate PAR, we employed a formula appropriate to use with an adjusted effect estimate. To estimate intermediate quantities needed to apply that formula, we used adjusted relative risk estimates from a previously published meta- analysis, as well as SEER cancer statistics and general population data from the third National ...


Modifications Of Phosphocaseinate Solutions Treated By Selective Adsorption, Nathalie Martin, Rafael Jiménez-Flores, Phillip S. Tong, Yves Pouliot, Michel Britten Mar 1999

Modifications Of Phosphocaseinate Solutions Treated By Selective Adsorption, Nathalie Martin, Rafael Jiménez-Flores, Phillip S. Tong, Yves Pouliot, Michel Britten

Dairy Science

The treatment of phosphocaseinate by adsorption with diatomaceous earths has been studied. The results suggest that magnesium and calcium silicates have a specific affinity for milk proteins. As a result, the ratio of individual casein types in phosphocaseinate solution can be manipulated.


Cryptic Luminescence In The Cold-Water Fish Pathogen Vibrio Salmonicida, P. M. Fidopiastis, Henning Sørum, E. G. Ruby Feb 1999

Cryptic Luminescence In The Cold-Water Fish Pathogen Vibrio Salmonicida, P. M. Fidopiastis, Henning Sørum, E. G. Ruby

Biological Sciences

The recent discovery that the fish pathogen Vibrio salmonicida is closely related to the luminous bacteria Vibrio fischeri and Vibrio logei suggested that V. salmonicida might also be capable of bioluminescence. Interestingly, cells of V. salmonicida were found to produce light in culture, but only when exposed to either an aliphatic aldehyde and/or the major V. fischeri autoinducer N-(3-oxo-hexanoyl)-l-homoserine lactone, a transcriptional activator of the luminescence (lux) genes. An extract of spent medium of V. salmonicida that should contain any V. salmonicida acyl-homoserine lactone autoinducer, when added to V. fischeri cells, led to an induction of their ...

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 ...


Nitrogen Utilization Efficiency Of Creeping Bentgrass Genotypes, Y. Kuo, David J. Wehner, T. W. Fermanian, John M. Swiader Jan 1999

Nitrogen Utilization Efficiency Of Creeping Bentgrass Genotypes, Y. Kuo, David J. Wehner, T. W. Fermanian, John M. Swiader

Office of the Dean (CAFES) Scholarship

A greenhouse study was conducted in a hydroponic system to determine the nitrogen (N) utilization efficiency (NUE) of 14 creeping bentgrass cultivars. There were significant differences among cultivars in plant tissue dry weight, tissue N content, root absorption efficiency (RAE), and NUE. Considering all plant tissue (whole plant), 'Penncross' accumulated the highest N accompanied with the highest whole plant dry weight (WPDW), while 'Allure' accumulated the lowest total Nand WPDW than all the other cultivars. The proportion of WPDW and total N partitioned to shoots was higher than partitioned to roots in each cultivar. On a whole plant basis, 'Regent ...

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 ...


Determining The Source Of Individuals: Multilocus Genotyping In Nonequilibrium Population Genetics, Neil Davies, Francis X. Villablanca, George K. Roderick Jan 1999

Determining The Source Of Individuals: Multilocus Genotyping In Nonequilibrium Population Genetics, Neil Davies, Francis X. Villablanca, George K. Roderick

Biological Sciences

Recently founded populations represent an enormous challenge for genetic analysis: new populations are often genetically impoverished, making it hard to find sufficiently variable markers, and what little variation is present tends to be ancestral, rendering phylogenetic methods inappropriate. Recently, novel genetic markers and new statistical analyses have made multilocus genotyping an invaluable tool in the fledgling field of nonequilibrium population genetics. Such advances are not of mere academic interest but address questions of great economic, medical and conservation significance.


Ontogenies Of Phototactic Behavior And Metamorphic Competence In Larvae Of Three Species Of Bugula (Bryozoa), Dean E. Wendt, Robert M. Woollacott Jan 1999

Ontogenies Of Phototactic Behavior And Metamorphic Competence In Larvae Of Three Species Of Bugula (Bryozoa), Dean E. Wendt, Robert M. Woollacott

Biological Sciences

The free swimming larvae of many marine invertebrates actively respond to light. Light cues can be used to regulate position in the water column and to facilitate encountering sites suitable for metamorphosis. We examined the ontogeny of larval phototaxis and the ontogeny of metamorphic competency in larvae from three congeneric species of bryozoans. Larvae of Bugula neritina are positively phototactic on emergence from the brood chamber, whereas larvae of B. simplex and B. stolonifera appear initially photoneutral when populations of larvae are examined. Larvae of all three species become photonegative with time. Temporally coincident with this change to negative phototaxis ...


Response To Dietary Dilution In An Omnivorous Freshwater Turtle: Implications For Ontogenetic Dietary Shifts, Shannon J. Mccauley, Karen A. Bjorndal Jan 1999

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 than do ...


Abundance Of Spiders And Insect Predators On Grapes In Central California, Michael J. Costello, Kent M. Daane Jan 1999

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 season. Chrysoperla carnea, Chrysoperla ...

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.
