Effects Of Food Deprivation, Age, Time Of Day, And Gamma Irradiation On Attraction Of Mexican Fruit Flies (Diptera: Tephritidae) To Two Synthetic Lures In A Wind Tunnel, David C. Robacker

Entomology Papers from Other Sources

The physiological condition of Mexican fruit flies, Anastrepha ludens (Loew), affected their attraction to 2 similar but qualitatively different synthetic lures in wind-tunnel bioassays. The 2 lures were BioLure (ammonium acetate and putrescine) and AMPu (ammonium carbonate, methylamine HCI, and putrescine) . Effects of food deprivation on attraction to the lures were smaller than the effects of sex, time of day, and irradiation. Sugar-fed, protein-starved flies were attracted more strongly than other hunger-status groups to the lures. Sugar-starved, protein-starved females were less responsive than other groups of females to AMPu. Protein-starved males were more responsive than protein-fed males to BioLure. …

Experiments To Maximize Growth In Captive Florida Pompano (Trachinotus Carolinus), Brian J. Hicks

HCNSO Student Theses and Dissertations

Florida pompano (Trachinotus carolinus) are highly prized food and sport fish indigenous to coastal areas of the southeastern United States. A commercially valuable fishery has historically existed in the Gulf of Mexico and on the South Atlantic seaboard. Efforts to economically culture Florida pompano in a captive environment were only partially successful. Four experiments were performed to explore the physical and environmental requirements of Florida pompano and other closely related species in the Family (Carangidae):

Experiment #1- Semi-natural spawning was induced with newly developed hormonal implants. to initiate and sustain semi-natural spawning in captive Florida pompano. Fish collected from the …

Parasitism Of Greenbugs (Homoptera: Aphididae) By Lysiphlebus Testaceipes (Hymenoptera: Braconidae) In Grain Sorghum: Implications For Augmentative Biological Control, Odair A. Fernandes, Robert J. Wright, Z. B. Mayo

Department of Entomology: Faculty Publications

Field cage studies were conducted to describe the relationship between the percentage of Lysiphlebus testaceipes (Cresson) parasitism (as measured by aphid mummies) and densities of greenbug, Schizaphis graminum Rondani, on grain sorghum, Sorghum bicolor L. In 1993 and 1994, a biotype E-susceptible grain sorghum hybrid was grown in field cages and L. testaceipes adults were released after each plant was infested with 20 biotype E greenbugs. The release rates were 0, 0.5, 1.0, and 2.0 wasps per plant in 1993, and 0, 0.16, 0.33, and 0.5 wasps per plant in 1994. Greenbugs and mummies were counted 1-2 times a week …

Two New Nymphalidae From Western North Carolina: New Subspecies Of Speyeria Aphrodite And Phyciodes Batesii, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Two new subspecies are described from Macon County, North Carolina, United States. Speyeria aphrodite cullasaja is characterized by dorsal melanism, especially in females, by usually lacking the dorsal FW basal spots in cell Cu1 and Cu2, and by a narrowed buff marginal band on the ventral HW (sometimes absent in females). Phyciodes batesii maconensis males are characterized by wholly yellow ventral hind wings devoid of any dark marginal dusting or whitish crescents; and females occasionally possessing, lightly dusted, brown margins and rarely having a silvered marginal ventral HW spot. PPhyciodes batesii maconensis larvae are gregarious Aster feeders. Females are …

Fall Field Report, August To November 1998, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

Larry Einemann kindly pointed out that in the Spring Report all his sightings from Pioneer's Park should have been attributed to Wilderness Park at Pioneer's Boulevard (in Lincoln). Larry noted that Pioneer's Park is a manicured Lincoln city park which is not good for birds except for in the vicinity of the embedded Chet Ager Nature Center. This was my (WRS) error; personally I have trouble even finding the Wilderness Park entrances, let alone naming them properly!

Another correction! John Sullivan pointed out that the 2 Summer Tanagers at Indian Cave SP on 10 August, 1997, were not his sighting. …

Parasitic Jaeger At Lake Mcconaughy, Stephen J. Dinsmore, W. Ross Silcock

Nebraska Bird Review

On 5 October, 1997, we joined Joel G. Jorgensen and John Sullivan for a pelagic trip on Lake McConaughy. A similar trip in late September 1996 yielded a Sabine's Gull, but we were really hoping to see a jaeger. From 7:00 to 8:30 a.m. we gradually worked our way from the dam towards the western end of the lake. Besides moderate numbers of Franklin's and Ring-billed Gulls, there were few birds on the lake. At approximately 8:45 a.m. Dinsmore noticed that all of the gulls at the western end of the lake had suddenly taken flight. Less than a minute …

Endemicity And Regional Biodiversity In Nebraska's Breeding Avifauna, Paul A. Johnsgard

Papers in Ornithology

I estimate that 215 bird species currently breed or have previously bred in Nebraska. This number compares with a total of 330 spe¬cies that breed or have bred in the Great Plains region south of Canada, as I defined that region in my book on the breeding birds of the Great Plains (Johnsgard, 1979). An analysis of the relative species diversity of Nebraska's breeding avifauna establishes several areas of unusual species richness and endemicity, these most important being the Missouri Valley and associated middle to lower Niobrara Valley, the Pine Ridge area of the northwestern Panhandle, and the entire Platte …

Phorbol 12-Myristate 13-Acetate Stimulates Lysophosphatidic Acid Secretion From Ovarian And Cervical Cancer Cells But Not From Breast Or Leukemia Cells, Zhongzhou Shen, Jerome Belinson, Richard E. Morton, Yan Xu

Chemistry Faculty Publications

Lysophosphatidic acid (LPA) is present in ascites from patients with ovarian cancer. It stimulates calcium release and growth of ovarian cancer cells bothin vitroandin vivo.Recently, we found that LPA levels were significantly elevated in plasma from patients with ovarian cancer and other gynecological cancers. In contrast, LPA levels were not elevated in patients with breast cancer and leukemias. In view of this, we investigated whether gynecological cancer cells could produce LPA. LPA was extracted from the supernatant of cells culturedin vitroand purified by thin layer chromatography. After hydrolysis and transmethylation, the fatty acid derivatives were analyzed by gas chromatography. We …

The Role Of Gap Junctions In Congenital Diseases Of The Heart, Scott Henry Britz-Cunningham

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Gap junctions are thought to have a crucial role in the synchronized contraction of the heart and in embryonic development. Connexin43, the major protein of gap junctions in the heart, is targeted by several protein kinases that regulate myocardial cell-cell coupling. We hypothesized that mutations altering sites critical to this regulation would lead to functional or developmental abnormalities of the heart.

Methods. Connexin43 DNA from 25 normal subjects and 30 children with a variety of congenital heart diseases was amplified by the polymerase chain reaction and sequenced. Mutant DNA was expressed in cell culture and examined for its effect …

Factors Influencing Venom Expenditure During Defensive Bites By Cottonmouths (Agkistrodon Piscivorus) And Rattlesnakes (Crotalus Viridis, Crotalus Atrox), Shelton Scott Herbert

Loma Linda University Electronic Theses, Dissertations & Projects

Although the quantity of venom expended when biting is an important aspect of the natural history of snakes, little is known regarding the quantities of venom expended during bites. Recent studies have shown that rattlesnakes appear capable of selectively allocating their venom reserves during predatory strikes, metering more venom into certain prey types and less into others. Despite much speculation, the quantities of venom expended during defensive bites are poorly understood. The purpose of this study was to examine the factors that influence venom expenditure during defensive bites by cottonmouths (Agkistrodon piscivorus), western rattlesnakes (Crotalus viridis) and western diamondbacks …

Principal Component Mapping Applied To Raman Microspectroscopy Of Fiber-Reinforced Polymer Composites, C. M. Stellman, K. S. Booksh, A. R. Muroski, M. P. Nelson, Michael L. Myrick

Faculty Publications

We describe the development and implementation of a spectroscopic Raman imaging system using Principal Component data analysis. Raman microspectroscopy followed by multivariate data analysis and principal component mapping has been used to investigate the spatial variations of chemical and physical properties at interfaces in glass-reinforced composites on the micrometer scale. A protocol for monitoring chemical and physical variances via multivariate statistics has been developed and a preliminary study of a "real world" glass-reinforced composite is presented. It is demonstrated that multivariate Raman imaging is more precisely interpretable than traditional univariate methods and that by appropriately choosing distinct spectral regions (such …

The Leukemic Protein Core Binding Factor Beta (Cbfbeta)-Smooth-Muscle Myosin Heavy Chain Sequesters Cbfalpha2 Into Cytoskeletal Filaments And Aggregates, Neeraj Adya, Terryl Stacy, Nancy A. Speck, Pu Paul Liu

Dartmouth Scholarship

The fusion gene CBFB-MYH11 is generated by the chromosome 16 inversion associated with acute myeloid leukemias. This gene encodes a chimeric protein involving the core binding factor β (CBFβ) and the smooth-muscle myosin heavy chain (SMMHC). Mouse model studies suggest that this chimeric protein CBFβ-SMMHC dominantly suppresses the function of CBF, a heterodimeric transcription factor composed of DNA binding subunits (CBFα1 to 3) and a non-DNA binding subunit (CBFβ). This dominant suppression results in the blockage of hematopoiesis in mice and presumably contributes to leukemogenesis. We used transient-transfection assays, in combination with immunofluorescence and green fluorescent protein-tagged proteins, to monitor …

5 | The Cave Of The Warrior: A Fourth Millenium Burial In The Judean Desert, Tamar Schick

IAA Reports—Monograph Series of the Israel Antiquities Authority

During the survey of the caves in the Jericho area, Cave No. 13 revealed a uniquely well-preserved burial dating to the early 4th millennium BCE, accompanied by burial goods that have rarely been preserved elsewhere, due to the conditions of the cave. The middle-aged male buried together with a unique flint knife anda wooden bow and arrows, among other gifts, was termed the “Warrior”, although he may have been a hunter rather than warrior. Other perishable objects that so rarely survive the millennia include textiles, mats, a basket and leather sandals. A wide range of research topics, analyses and conservation …

Breeding Productivity Does Not Decline With Increasing Fragmentation In A Western Landscape, J. J. Tewksbury, Thomas E. Martin

Wildlife Biology Faculty Publications

Fragmentation of breeding habitat may cause declines in many bird populations. Our perception of the demographic effects of habitat fragmentation comes primarily from studies in the midwestern and eastern United States and Scandinavia. We know very little about the demographic effects of anthropogenically caused habitat fragmentation in habitats prone to natural disturbance, as is typical of most forest types in the western United States. We located and monitored 1916 nests on eight sites located in mostly forested landscapes and eight sites located in primarily agricultural landscapes to study the effects of landscape-level fragmentation on nest predation and brood parasitism in …

Identification And Characterization Of Spcu, A Chaperone Required For Efficient Secretion Of The Exou Cytotoxin, Viviane Finck-Barbançon, Timothy L. Yahr, Dara W. Frank

Dartmouth Scholarship

In recent studies, we have shown that Pseudomonas aeruginosa strains that are acutely cytotoxic in vitro damage the lung epithelium in vivo. Genetic analysis indicated that the factor responsible for acute cytotoxicity was controlled by ExsA and therefore was part of the exoenzyme S regulon. The specific virulence determinant responsible for epithelial damage in vivo and cytotoxicity in vitro was subsequently mapped to the exoU locus. The present studies are focused on a genetic characterization of the exoU locus. Northern blot analyses and complementation experiments indicated that a region downstream of exoU was expressed and that the expression of this …

Ecological Effects Of Major Storms On Coastal Watersheds And Coastal Waters: Hurricane Bob On Cape Cod, I. Valiela, P. Peckol, C. D'Avanzo, J. Kremer, D. Hersh, K. Foreman, K. Lajtha, B. Seely, W. R. Geyer, T. Isaji, R. Crawford

Biological Sciences: Faculty Publications

Hurricane Bob, a category 3 storm, made landfall on Cape Cod in August 1991, and its effects on watersheds and adjoining estuaries were detected in the ongoing studies being caried out as part of the Waquoit Bay Land Margin Ecosystems Research project. On land, Bob had only minor overall effects on forests; localized wind bursts did snap and break trees in small and widely scattered forest parcels. Wind stripped up to half the leaves of deciduous trees and many herbaceous plants on the watershed, and most remaining leaves were damaged by salt, so that by the end of Aug, Cape …

For Shade And Comfort: Ornamental Plants In Nineteenth- Century Midwestern Domestic Landscapes, Cheryl Lyon-Jenness

Dissertations

This dissertation investigates the extent and type of ornamental plant use in nineteenth-century Midwestern domestic landscapes, considers reasons for expanded horticultural interest between 1850 and 1880, and explores the significance of ornamental plants as part of Midwestern material culture.

Content analysis of over seven hundred lithographic images of homes and homegrounds from three southeastern Michigan counties, combined with demographic information, confirmed widespread ornamental plant use among an economically and culturally diverse group of Midwesterners by the 1870s. A number of cultural trends encouraged this expanded horticultural interest Exploration of readily available midnineteenth- century newspapers, magazines, and advice manuals revealed that …

Analysis Of Protein And Rna Interactions Of The Hiv-1 Rev Protein, John Francis

Loma Linda University Electronic Theses, Dissertations & Projects

The HIV-1 Rev protein enters the nucleus via it’s nuclear localization sequence/RNA binding domain and interacts with a ≈234 nt region of viral RNA, termed the Rev Response Element (RRE), which is located in the env region of unspliced and singly-spliced HIV-1 mRNA. The Rev nuclear export sequence (NES) then mediates translocation of the viral transcript to the cytoplasm, allowing for translation of viral structural genes and active virion formation. We report identification of two yeast nucleopore proteins, NUP49 and NUP100, that have been found to interact with Rev in vivo using the yeast two-hybrid system. NUP49 and NUP100 contain …

Mathematical Model Of Paper Discoloration By Ink Particles, Zbigniew W. Slotwinski

Masters Theses

The goal of this experiment is to investigate how changes in the size and number of ink particles will affect the final brightness of the filter pad.

It was assumed that any differences in brightness of the used Millipore filters were due to change in the average particle size, given the same mass of ink solids on each filter. However, such simplified interpretation of image analysis proved to be inadequate to solve this complex problem.

The correlation between the particle area, number of particles, and brightness drop was established using an algorithm based on the particle area and the square …

Bird Banding Notes From Ruth Green, Ruth Green

Nebraska Bird Review

On 29 April 1998, while working with school children from the Chadron Public Schools, Ruth banded a Pine Siskin at Nebraska's Chadron State Park, Dawes County. Approximately seven and a half months later, on 12 December, this same bird was recovered beneath a feeder in Springfield, Oregon. The Pine Siskin was dead, perhaps a victim of disease sweeping the siskin population on the West Coast. This particular occurrence is noteworthy for the distance traveled both west and north.

The Summer Tanager pictured below was also banded by Betty. She banded the AHY-F (After Hatching Year, Female) Summer Tanager on 10 …
