Evaluation Of Bobwhite Quail Surveys In Kansas, Roger Wells, Keith Sexson, Gary L. Doster

National Quail Symposium Proceedings

Statistical analysis of selected Kansas bobwhite (Colinus virginianus) population and harvest surveys is presented. Survey techniques evaluated include roadside counts by rural mail carriers (RMCS), April roadside counts, whistling cock counts, random summer brood counts (RSBC), interviews of hunters contacted during the hunting season, wing collection envelopes distributed to hunters, and a mail questionnaire harvest survey of hunters. Significant differences (P < 0.05) between years and between survey regions existed for the April RMCS, April roadside count (coveys/observer), June whistle count, RSBC (young/adult and young/adult hen), and July RMCS, Correlation tests indicated significant (P < O, 1 to 0.001) correlation coefficient (r) values between many of the population surveys, and between many of the population surveys and harvest parameters. The October RMCS is the best single predictor of harvest parameters. When the October RMCS (quail/100 miles) is used in association with adults/observer (RSBC) and total quail/observer (RSBC), higher R2 values are obtained as determined by stepwise multiple regression with harvest parameters,

Land Use And Bobwhite Populations In An Agricultural System In West Tennessee, Jay H. Exum, Ralph W. Dimmick

National Quail Symposium Proceedings

The efficacy of a computer assisted habitat evaluation system (IMGRID: Information Management on a GRID cell system) was tested on Ames Plantation in west Tennessee. Habitat characteristics and bobwhite (Colinus virginiana) population size were compared to delineate the effect of land use changes on bobwhites. Significant changes in land use occurred. Pastures decreased from 120.4 ha in 1966 to 35.0 ha in 1980, while soybeans increased from 102.4 to 193. 1 ha. Idle land decreased from 212.9 ha to 178.6 between 1966 and 1980. Bobwhite population size was negatively correlated with the area maintained in soybeans (r = -0.63) and …

Bobwhite Quail And Changing Land Use, William D. Klimstra

National Quail Symposium Proceedings

(Invited Paper) The downward trend of bobwhite quail (Colinus virginianus) numbers nationally is well established. Generally, this reflects deterioration and widespread loss of suitable habitat resulting from changes in land use. Since the 1940s research on the quail seems to have dwindled with few indications of on-going studies. There is much emphasis on setting aside areas as wilderness and natural areas and creating special funds, but these activities cannot accommodate the special needs of quail except in a general way. The intense emphasis on the economics of agriculture, use of chemicals in farming, and the activities of government and agricultural …

A Model For Determining Least-Cost Quail Stocking Programs, Charles H. Lobdell, Robert H. Giles Jr.

National Quail Symposium Proceedings

A model is presented to allow the calculation of the minimum cost of providing an acceptable level of quail hunter success expressed as kill per day. The model is based on a Poisson distribution for hunter kill per day, the number of hunters, their success rates, quail survival rates, various costs of quail production and release, stocking levels, and frequency of stocking. An example is given.

Seasonal Changes And Habitat Influencing Helminthiasis In Bobwhite Quail, M. F. Hansen, R. J. Robel

National Quail Symposium Proceedings

Two hundred forty-four bobwhite quail (Colinus virginianus) were collected in Kansas and examined for helminths during 1963-1966. Total incidence of helminthic infection was 23%; 24% in juveniles and 22% in adults. Total incidence of nematode infection was 13%, cestodes, 10% and no trematodes were recovered. Six species of nematodes, 1 species of cestode, and 1 species of acanthocephalan were found in the quail examined. Peak incidence of infection occurred from September to November during the 3- yr study .. Incidence of infection was greater during February-April 1965, than during similar periods of 1964 and 1966. Bobwhites collected within 0.5 mile …

Simulation Studies Of Quail Hunting Success Associated With Ecological Succession Of Planted Pine Stands, John D. Gavitt, Robert H. Giles Jr.

National Quail Symposium Proceedings

A concept paper of a methodology is presented for explaining past populations and predicting future populations of bobwhite quail (Colinus virginianus), as a function of forest changes. The methodology is applicable to large landholdings, regions, and states. It relates, using computer technology, the number of potential covey flushes per 100 acres per day to the age of forest stands or ecological succession curves. By summing quail flush curves over a large area, area-wide yields may be obtained. Flushes are modified by a shooting-quality factor and birds per covey. The computer-generated output tables provide an inventory, a historical overview, and projected …

Bobwhite Whistling Activity And Population Density On Two Public Hunting Areas In Illinois, Jack A. Ellis, Keith P. Thomas, Paul Moore

National Quail Symposium Proceedings

Eight years of data from 2 public hunting areas in southern Illinois demonstrate high multiple correlations (r = 0.97 and 0.84) for prebreeding densities and call indices with the prehunt densities of bobwhites (Colinus virginianus). Models derived from multiple correlation analyses produced satisfactory predictions of prehunt densities. The average number of calls per stop was the key element in the predicting model. The number of whistling cocks heard per stop is of limited value as an index because of difficulty in determining numbers when more than 7 whistling cocks are within hearing. The mod~ls for the 2 areas appear different, …

Some Aspects Of The Dynamics Of A Hunted Bobwhite Population, John L. Roseberry, W. D. Klimstra

National Quail Symposium Proceedings

Dynamics of a hunted bobwhite population have been investigated on a 1,450-acre study area near Carbondale, Illinois since 1952. Habitat conditions have not changed greatly during the study, and November densities have oscillated regularly about a rather stable long-term mean. Most of the variance of annual rates of population change is due to variation in net productivity from spring to fall rather than to variation in net losses from fall to spring. Population declines from November to April averaged 66% (range 36 to 81%); about 0.66 of this resulted from hunting. Post-hunting mortality, which was slightly density-related, partially compensated for …

Diseases And Parasites Of The Bobwhite, Forest E. Kellog, Gary L. Doster

Diseases and parasites of bobwhites, location in the bird of the lesion or parasite, and geographic areas of occurrence are note.

Effects Of Ddt On Steroid Metabolism And Energetics In Bobwhite Quail (Colinus Virginianus), Sheldon Lustick, Terry Voss, Tony J. Peterle

National Quail Symposium Proceedings

Female bobwhite quail (Colinus virginianus) fed low levels (5 ppm) of DDT in their diets showed increased enzyme induction in the liver and consequently a significant increase in steroid (progesterone) metabolism (a mean of 54% conversion of progesterone to its more polar metabolite in experimentals compared to a mean of 24.1% conversion in controls). The mean conversion of testosterone to its polar metabolite (25.1%) in experimental males was greater than in the controls (mean 18.1%) but was only significantly greater in certain males. There was a correlation (r = 0.7 P<0.01) between percent body weight of testes and percent conversion of testosterone to its metabolites (the smaller the testes the greater the conversion). A correlation (r = 0.66 P<0.02) was also found between circulating levels of DDE, DDT, and testes size (the higher the pesticide level the smaller the testes).
Dietary levels of DDT (10,50,100,150 ppm) affected the energetics …

Energetic Requirements For Egg-Laying Bobwhites, Ronald M. Case

National Quail Symposium Proceedings

As part of an extensive bioenergetics study of bobwhite quail (Colinus virginianus), energy requirements for egg laying were determined. Caloric values for eggs averaged 5.489 kcal/g. Net energetic efficiency of converting productive energy into eggs was conservatively estimated to be 54% for quail laying at a rate of 0.45 egg/bird-day at 25 C. Assuming that those values were the same for quail laying a 10-g egg at a rate of 1 egg/bird-day resulted in an energy requirement of 69.645 kcal/bird-day. This is an energy demand equivalent to that of existence alone at about -3.3 C

Body Fat Content Of Bobwhites In Relation To Food Plantings In Kansas, Robert J. Robel

National Quail Symposium Proceedings

A wildlife habitat improvement program was initiated on the Fort Riley Military Reservation in 1961 to increase winter food supplies for bobwhite quail (Colinus virginianus). As part of an ongoing evaluation of this program, 164 bobwhite quail were collected during the fall and winter of 1968-72 for fat analysis. Fat content in carcasses of birds collected <600 m from a food plot was compared with fat content of birds collected >900 m from a food plot.
During winter months, birds collected near a food plot were significantly (P<0.10 to P<0.05) heavier than birds not having access to a food plot. Fat content of birds close to a food plot was likewise greater (P<0.10 to P<0.01) than fat content in birds not using food plots. Calculations indicate that birds close to food plots have sufficient energy reserves to provide a 79% greater protection against brief periods of food deprivation than birds far from a food plot. Fat energy reserves alone in a quail close to a food plot could provide sufficient energy for 2.0 days of survival whereas quail far from food plots contained fat energy reserves sufficient for only 1.1 days of survival.
Reserve energy for animals is stored in the body mainly in the form of fatty acids. The quantity of stored reserve energy (fat) may be critical …

Bobwhite Quail Population Dynamics: Relationships Of Weather, Nesting, Production Patterns, Fall Population Characteristics, And Harvest In Missouri Quail, Jack A. Stanford

National Quail Symposium Proceedings

For 25 years Missouri has investigated bobwhite quail (Colinus virginianus) behavior, production, and population response to 4 major types of weather. Ten population parameters are examined annually to compare effects of Normal, Wet-Deluge, Snow-Cold and Drought weather years on quail populations,
Different types of weather are related to varying annual quail abundance by affecting productivity and survival and influencing relative levels of annual harvest and hunter interest. Normal and Wet-Deluge years yield favorable fall quail populations and satisfactory hunting. Years having winters of severe snow and cold have high breeder losses, low production, and reduced hunting success. In years having …

Early Quail Hunting Season In Tennessee: Reasons And Results, Chester A. Mcconnell

National Quail Symposium Proceedings

Bobwhite quail (Colinus virginianus) wings were collected and aged from 1952 through 1970. The wing age data indicated that Tennessee's quail hunting season could begin 20 days earlier than the traditional Thanksgiving Day opening, providing a larger quail harvest. A study involving a season opening date of 5 November was conducted on Laurel Hill Wildlife Management Area resulting in an 18% increase in quail kill over previous years. Only 18% of the quail bagged on Laurel Hill were <12 weeks of age, indicating that birds were sufficiently developed to provide good sport. Based on these earlier studies, the Commission opened the statewide quail season on 6 November 1971. A total of 5,270 quail wings were collected and aged during the early season. An estimated 180,000 additional quail were harvested as a result of the earlier season. Approximately 18 to 19% of the quail were <12 weeks of age. Based on data resulting from a questionnaire, approximately 80% of the quail hunters furnished information favorable to the early season. Weather conditions during the early season were unseasonably warm, but 64% of the hunters indicated that warm weather was only a minor problem. Landowners (87%) indicated that unharvested crops were only a minor problem. Hunters (80%) indicated that young quail presented only minor problems. Sportsmen responding to the questionnaire averaged 8.1 hunting trips and bagged an average of 5.0 quail per trip in November.

Managing Bobwhites In The Cutover Pinelands Of South Florida, William H. Moore

National Quail Symposium Proceedings

Because the principles governing production of quail are similar throughout its range, only problems and techniques unique to the flat-woods of southwest Florida are discussed. A description of these pine-lands includes geology and soils, climate and key plant communities. The Florida bobwhite and its foods and other needs are discussed briefly. A major portion of the text is concerned with the effects of primary land uses on quail habitat, and management modifications to improve quail production.

Changes Of Covey Affiliation By Bobwhite Quail In Tennessee, Noel S. Yoho, Ralph W. Dimmick

National Quail Symposium Proceedings

This study was conducted on a 214-acre area of the Ames Plantation, Fayette County, Tennessee. Information on behavior of bobwhite quail (Colinus virginianus) during winter was obtained through flushing, trapping, color-marking, and telemetering quail during January-March, 1970. Interchange of quail between coveys was common; at least 20 incidences of change in covey affiliation were recorded. An average covey lost and gained a member every 3 days. Rapid replacement of birds lost from covey ranges was attributed to communication between coveys.

Second Broods In Bobwhite Quail, Jack A. Stanford

National Quail Symposium Proceedings

Data on second broods in bobwhite quail is limited due to a lack of information on molting patterns, quiescence of female gonads, nesting chronology, and parental behavior in males and females. An analysis of these factors is presented along with a discussion of 19 occurrences of second-clutches in Missouri. The impact of second broods on quail populations is discussed.

Utilization Of Genomics For Risk Assessment And Molecular Subtyping To Improve Treatment Strategy In Breast Cancer, Lisa Eileen Blumencranz

Open Access Dissertations

Death from breast cancer began a decline in the 1990’s. One widely accepted reason for this reduction was the discovery that breast cancer can be uniquely defined at the molecular level by oncogenes and tumor suppressor genes including, but not limited to, EGFR, AKT, ErbB2, PI3K, TP53, BRCA1/2, and PTEN. These genes and potential mutations within, can drive constitutive activation of aberrant signaling that can induce and sustain tumorigenesis. More importantly, these genes represent new avenues for possible markers and therapies. In the wake of this molecular biology discovery, there was an influx of new breast cancer treatments to the …

Survey Of Hatching Spines Of Bee Larvae Including Those Of Apis Mellifera (Hymenoptera: Apoidea), Jerome G. Rozen Jr., Corey Shepard Smith, James H. Cane

All PIRU Publications

This article explores the occurrence of hatching spines among bee taxa and how these structures enable a larva on hatching to extricate itself from the egg chorion. These spines, arranged in a linear sequence along the sides of the first instar just dorsal to the spiracles, have been observed and recorded in certain groups of solitary and cleptoparasitic bee taxa. After eclosion, the first instar remains loosely covered by the egg chorion. The fact that this form of eclosion has been detected in five families (Table 1 identifies four of the families. The fifth family is the Andrenidae for which …

T-Dna-Genome Junctions Form Early After Infection And Are Influenced By The Chromatin State Of The Host Genome, Shay Shilo, Pooja Tripathi, Cathy Melamed Bessudo, Oren Tzfadia, Theodore R. Muth, Avraham A. Levy

Publications and Research

Agrobacterium tumefaciens mediated T-DNA integration is a common tool for plant genome manipulation. However, there is controversy regarding whether T-DNA integration is biased towards genes or randomly distributed throughout the genome. In order to address this question, we performed high-throughput mapping of T-DNA-genome junctions obtained in the absence of selection at several time points after infection. T-DNA-genome junctions were detected as early as 6 hours post-infection. T-DNA distribution was apparently uniform throughout the chromosomes, yet local biases toward AT-rich motifs and T-DNA border sequence micro-homology were detected. Analysis of the epigenetic landscape of previously isolated sites of T-DNA integration in …

Mobilization Studies In Mice Deficient In Sphingosine Kinase 2 Support A Crucial Role Of The Plasma Level Of Sphingosine-1-Phosphate In The Egress Of Hematopoietic Stem Progenitor Cells, Mateusz Adamiak, Lakshman Chelvarajan, Kevin R. Lynch, Webster L. Santos, Ahmed Abdel-Latif, Mariusz Z. Ratajczak

Gill Heart & Vascular Institute Faculty Publications

Sphingosine-1-phosphate (S1P) is a bioactive lipid involved in cell signaling and, if released from cells, also plays a crucial role in regulating the trafficking of lympho-hematopoietic cells, including primitive hematopoietic stem/progenitor cells (HSPCs). It has been demonstrated that S1P chemoattracts HSPCs, and its level in peripheral blood creates a gradient directing egress of these cells during mobilization. In this paper we analyzed hematopoiesis in mice deficient in sphingosine kinase 2 (Sphk2-KO mice) and studied the effect of this mutation on plasma S1P levels. We found that Sphk2-KO mice have normal hematopoiesis, and, in contrast to Sphk1-KO mice, the circulating S1P …

Consequences Of Severe Habitat Fragmentation On Density, Genetics, And Spatial Capture-Recapture Analysis Of A Small Bear Population, Sean Mccarthy Murphy, Ben C. Augustine, Wade Allen Ulrey, Joseph Maddox Guthrie, Brian K Scheick, J. Walter Mccown, John J. Cox

Forestry and Natural Resources Faculty Publications

Loss and fragmentation of natural habitats caused by human land uses have subdivided several formerly contiguous large carnivore populations into multiple small and often isolated subpopulations, which can reduce genetic variation and lead to precipitous population declines. Substantial habitat loss and fragmentation from urban development and agriculture expansion relegated the Highlands-Glades subpopulation (HGS) of Florida, USA, black bears (Ursus americanus floridanus) to prolonged isolation; increasing human land development is projected to cause ≥ 50% loss of remaining natural habitats occupied by the HGS in coming decades. We conducted a noninvasive genetic spatial capture-recapture study to quantitatively describe the …

Measuring Nurses' Perceptions Of Collaborative Governance As A Method Of Assessing Transformation Of Organizational Culture, Jaynelle F. Stichler, Maria Del Carmen Colombo, Debra Milbert Poeltler

International Nursing Research Congress (INRC)

Purpose: This completed study describes the measurement of nurses" perceptions of collaborative governance (CG) over 5 years after implementation of a CG structure developed to transform culture and empower nurses to be more involved in decision making. The study is important since few evidence-based studies regarding CG exist in the literature.

Transformation leaders inspire others to achieve more than they thought possible for themselves (Porter-O"Grady & Malloch, 2015). The Magnet culture requires transforming the organization culture and facilitating leadership growth and empowerment of all nurses in the organization (Dearmon, 2015). CG is a structure and process used to change organizational …

Gene Drives, Nature, Governance: An Ethnographic Perspective, Irus Braverman

Contributions to Books

Published as chapter 3 in Gene Editing, Law, and the Environment, Irus Braverman, ed.

Synthetic gene drives raise ethical, ecological, and legal questions that are sometimes difficult to grasp. What is clear, however, is that the power to directly alter not just a singular form of life but the genetics of entire populations and species are currently both under-regulated and under-theorized. In place of state regulations, what seems to be emerging is a form of self-regulation by the gene drive scientists themselves. My chapter draws on in-depth interviews with several prominent gene drive scientists to explore their approach toward nature, …

The Discovery Of Xy Sex Chromosomes In A Boa And Python, Tony Gamble, Todd A. Castoe, Stuart V. Nielsen, Jason L. Banks, Daren C. Card, Drew R. Schield, Gordon W. Schuett, Warren Booth

Biological Sciences Faculty Research and Publications

For over 50 years, biologists have accepted that all extant snakes share the same ZW sex chromosomes derived from a common ancestor [1, 2, 3], with different species exhibiting sex chromosomes at varying stages of differentiation. Accordingly, snakes have been a well-studied model for sex chromosome evolution in animals [1, 4]. A review of the literature, however, reveals no compelling support that boas and pythons possess ZW sex chromosomes [2, 5]. Furthermore, phylogenetic patterns of facultative parthenogenesis in snakes and a sex-linked color mutation in the ball python (Python regius) are best explained by boas and pythons possessing …

Methods For Sampling Density And Basal Area Of Multi-Trunked Trees: Juniperus Osteosperma In Pinyon-Juniper Vegetation, John L. Vankat

Western North American Naturalist

Sampling the density and basal area of trees is fundamental to quantitatively characterizing forests and woodlands. Commonly used sampling methods are well-suited for trees with single trunks, but are these methods also suitable for sampling multi-trunked trees? This question is especially important where multi-trunked trees are common, as is the case for Utah juniper ( Juniperus osteosperma, JUOS), a codominant of large areas of pinyon-juniper vegetation in western North America. This study addresses the question of suitability by comparing 3 methods for sampling JUOS. The Dbase Method has been commonly used, and it focuses on the bases of trees for …
