The Bobwhite Quail  

NLE Websites -- All DOE Office Websites (Extended Search)

Bobwhite Quail Bobwhite Quail Nature Bulletin No. 232-A May 28, 1966 Forest Preserve District of Cook County Seymour Simon, President Roland F. Eisenbeis, Supt. of Conservation THE BOBWHITE QUAIL While plowing on a May morning many years ago, my father saw a crow, passing overhead, drop something white from its beak. Before the crow could retrieve it, he shouted and ran to pick up -- an egg, unbroken on the soft newly turned soil. Suspecting that it was a quail's egg, he wrapped it in his handkerchief and, at noon, had mother place it with the incubating eggs under a "setting" hen. A few days later, out popped a damp chick scarcely larger than a bumblebee. Within a few hours its downy feathers had fluffed out into fine brown fuzz, with a dark streak down its back, and it was scampering about in a shoe box in the warm kitchen. Fed bits of egg yolk, meal, live crickets and flies, that baby quail soon became very tame and would creep inside the cuff of a sleeve or nestle under a cupped hand. After a week or two it had well- developed wing feathers and was trying to fly.

Distribution of /sup 153/Gd in F1 quail  

SciTech Connect

Eggs laid by /sup 153/Gd-labeled Japanese quail were collected each day for 24 days. Maximum transference of the lanthanide to an oocyte approximated 27% of the dose given the quail and occurred usually for the egg collected on the third day. The 24 largest oocytes from each of 2 quail were removed 18 hr after labeling the quail. The curve for a plot of percent /sup 153/Gd vs. gram of oocyte for these 24 oocytes approximated a log-log function. Eggs double-labeled with /sup 153/Gd and Sudan black B showed no label in the latebra. Quail hatched from labeled eggs were dissected at various times up to 67 days of age. The percent of egg /sup 153/Gd that was found in the F1 quail decreased from 100% to approximately 55% during the first 14 days. The percentage recovery for mature quail was 55.8%. The major portion of the /sup 153/Gd present in each F1 quail was found in the yolk sac and ranged from 96.0% for hatchlings a few hours old to 73.3% for mature quail. The weight of the yolk sac decreased from .7 g for hatchlings to .04 g for mature quail. The first 5 eggs laid by producing F1 quail contained a total of .643% of the /sup 153/Gd in these quail. The graph curve for these eggs for percent /sup 153/Gd vs. day of collection approximated an exponential function, in contrast to the marked maximum seen for /sup 153/Gd levels in eggs laid by the parent quail.

Influence of a mobile robot on the spatial behaviour of quail chicks  

Science Journals Connector (OSTI)

Quail chicks encountered an autonomous mobile robot during their early development. The robot incorporated a heat source that stimulated following of chicks. The spatial behaviour of grown-up chicks was tested in an exploration test and a detour test. Chicks that grew with the mobile robot exhibited better spatial abilities than chicks grown with a static heat source. We discuss these results in the perspective of animal?robot interaction and of the role of early spatial experience on the behavioural development.

Aquaporins are major determinants of water use efficiency of rice plants in the field  

Science Journals Connector (OSTI)

Abstract This study aimed at specifying the reasons of unbalanced water relations of rice in the field at midday which results in slowing down photosynthesis and reducing water use efficiency (WUE) in japonica and indica rice under well-watered and droughted conditions. Leaf relative water content (RWC) decreased in the well-watered plants at midday in the field, but more dramatically in the droughted indica (75.6 and 71.4%) than japonica cultivars (85.5 and 80.8%). Gas exchange was measured at three points during the day (9:00, 13:00 and 17:00). Leaf internal CO2 (Ci) was not depleted when midday stomatal depression was highest indicating that Ci was not limiting to photosynthesis. Most aquaporins were predominantly expressed in leaves suggesting higher water permeability in leaves than in roots. The expression of leaf aquaporins was further induced by drought at 9:00 without comparable responses in roots. The data suggest that aquaporin expression in the root endodermis was limiting to water uptake. Upon removal of the radial barriers to water flow in roots, transpiration increased instantly and photosynthesis increased after 4 h resulting in increasing WUE after 4 h, demonstrating that WUE in rice is largely limited by the inadequate aquaporin expression profiles in roots.

Eisenbeis, Supt. of Conservation DOMESTIC CHICKENS The domestic chicken belongs to a family of hen-like ground-dwelling birds which includes the quail, grouse, partridge, pheasant, turkey, guineafowl and peafowl. Because of their anatomy and relatively small brains, some scientists think that they, -- rather than the ostrich, emu, cassowary and other flightless kinds -- are the most primitive birds. Chickens, undoubtedly, are the silliest of all domestic animals. There is an old riddle: "Why does a chicken cross the road?" Anyone who has seen a squawking hen try to run or fly just ahead of an automobile, will answer: "No brains ".

Eisenbeis, Supt. of Conservation BIRD PROTECTION IN ILLINOIS Very few people are indifferent about birds. Almost every bird is the feathered friend of somebody or some organization ready to do battle in its behalf. At present, in Illinois, songbirds and most other wild birds, together with their nests and eggs, are completely protected by law at all times. A few kinds, called game birds, may be shot by hunters -- pheasants and quail, also migratory ducks, geese, coots, jacksnipes, woodcocks, and doves. Such hunting must be done with shotguns in certain places in certain open seasons with many other detailed restrictions. Now, even crow hunters are licensed. The only unprotected birds are those three immigrants or exotics: the English sparrow, the European starling and the "domestic " pigeon. These, too, have their friends .

Burlington Bottoms Wildlife Mitigation Project. Final Environmental Assessment/Management Plan and Finding of No Significant Impact.  

SciTech Connect

Bonneville Power Administration (BPA) proposes to fund wildlife management and enhancement activities for the Burlington bottoms wetlands mitigation site. Acquired by BPA in 1991, wildlife habitat at Burlington bottoms would contribute toward the goal of mitigation for wildlife losses and inundation of wildlife habitat due to the construction of Federal dams in the lower Columbia and Willamette River Basins. Target wildlife species identified for mitigation purposes are yellow warbler, great blue heron, black-capped chickadee, red-tailed hawk, valley quail, spotted sandpiper, wood duck, and beaver. The Draft Management Plan/Environmental Assessment (EA) describes alternatives for managing the Burlington Bottoms area, and evaluates the potential environmental impacts of the alternatives. Included in the Draft Management Plan/EA is an implementation schedule, and a monitoring and evaluation program, both of which are subject to further review pending determination of final ownership of the Burlington Bottoms property.

1,3,5-trichloro-2-(4-nitrophenoxy)benzene (CNP) in water, sediments, and shellfish of the Ishikari River  

SciTech Connect

Since organochlorine compounds are known to be accumulated in benthic animals and CNP is very persistent in aquatic animals, shellfish might be useful as an indicator of environmental contamination by CNP. In order to understand the correlations between the concentrations in shellfish, water and sediments, it is necessary to investigate their temporal changes and the residue half-life time of CNP in the environment. For this purpose, CNP-free shellfish (Corbicula japonica) were transferred to fixed point in the lower reaches of the Ishikari River, and the CNP concentrations in shellfish, water and sediments, before and after CNP application, were examined biweekly from May to August and monthly from September to December 1984. The present paper will show that shellfish can be a biological indicator for CNP contamination in the river.

Wildlife toxicity extrapolations: Dose metric  

SciTech Connect

Ecotoxicological assessments must rely on the extrapolation of toxicity data from a few indicator species to many species of concern. Data are available from laboratory studies (e.g., quail, mallards, rainbow trout, fathead minnow) and some planned or serendipitous field studies of a broader, but by no means comprehensive, suite of species. Yet all ecological risk assessments begin with an estimate of risk based on information gleaned from the literature. One is then confronted with the necessity of extrapolating toxicity information from a limited number of indicator species to all organisms of interest. This is a particularly acute problem when trying to estimate hazards to wildlife in terrestrial systems as there is an extreme paucity of data for most chemicals in all but a handful of species. This section continues the debate by six panelists of the ``correct`` approach for determining wildlife toxicity thresholds by examining which dose metric to use for threshold determination and interspecific extrapolation, Since wild animals are exposed to environmental contaminants primarily through ingestion, should threshold values be expressed as amount of chemical in the diet (e.g., ppm) or as a body weight-adjusted dose (mg/kg/day)? Which of these two approaches is most relevant for ecological risk assessment decision making? Which is best for interspecific extrapolations? Converting from one metric to the other can compound uncertainty if the actual consumption rates of a species is unknown. How should this be dealt with? Is it of sufficient magnitude to be of concern?

Wildlife toxicity extrapolations: Allometry versus physiologically-based toxicokinetics

This is a particularly acute problem when trying to estimate hazards to wildlife in terrestrial systems as there is an extreme paucity of data for most chemicals in all but a handful of species. The question arises of how interspecific extrapolations should be made. Should extrapolations be limited to animals within the same class, order, family or genus? Alteratively, should extrapolations be made along trophic levels or physiologic similarities rather than by taxonomic classification? In other words, is an avian carnivore more like a mammalian carnivore or an avian granivore in its response to a toxic substance? Can general rules be set or does the type of extrapolation depend upon the class of chemical and its mode of uptake and toxicologic effect?

Should the lowest observable effect level (LOAEL) be used or is it more appropriate to use the no observable effect level (NOAEL)? What are the short-comings of using either of these point estimates? Should a ``benchmark`` approach, similar to that proposed for human health risk assessments, be used instead, where an EC{sub 5} or EC{sub 10} and associated confidence limits are determined and then divided by a safety factor? How should knowledge of the slope of the dose-response curve be incorporated into determination of toxicity threshold values?

Should only mortality, growth, or reproductive endpoints be used? Since toxicity threshold values may be used to make management decisions, should values related to each measurement endpoint be presented to allow the risk assessor to choose the measurement endpoint most relevant to the assessment questions being asked, or is a standard approach that uses the lowest value that causes a toxicologic response in any system of the animal a more appropriate, conservative estimate?

Quantitative determination of salvinorin A, a natural hallucinogen with abuse liability, in Internet-available Salvia divinorum and endemic species of Salvia in Taiwan  

Science Journals Connector (OSTI)

Abstract In recent years, recreational use of Salvia divinorum (Lamiaceae), a herbal drug that contains a hallucinogenic ingredient, salvinorin A, has become a new phenomenon among young drug users. In Taiwan, as in many other countries, dry leaves of S. divinorum and its related concentrated extract products are available via the Internet. Besides S. divinorum, there are many endemic Salvia species whose salvinorin A content is yet unknown. To understand the abuse liability of these products, the aim of this study was to assess the concentration of salvinorin A in endemic Salvia species and Internet-available salvinorin A-related products. Samples of S. divinorum were purchased via the Internet and samples of eight endemic species of Salvia were collected in Taiwan, including S. arisanensis Hayata, S. coccinea Juss. ex Murr, S. hayatana Makino ex Hayata, S. japonica Thumb. ex Murr, S. nipponica Miq. Var. formosana (Hayata) Kudo, S. scapiformis Hance, S. tashiroi Hayata. Icon. PI. Formosan, and S. keitaoensis Hayata. The content of salvinorin A was determined by high performance liquid chromatography (HPLC). Salvinorin A was extracted from the dry leaves of S. divinorum and endemic species of Salvia with methanol and analyzed on a C-18 column by isocratic elution with a mobile phase of acetonitrile–water. Salvinorin A was detected in S. divinorum, but not in the endemic Salvia species of Taiwan. Therefore, endemic species of Salvia in Taiwan may not possess hallucinogenic potential. However, the potential harm from S. divinorum available via the Internet should be thoroughly assessed in Taiwan, and control measures similar to those implemented in many other countries should be considered.

Simultaneous determination of triazine herbicides in rice by high-performance liquid chromatography coupled with high resolution and high mass accuracy hybrid linear ion trap-orbitrap mass spectrometry  

Science Journals Connector (OSTI)

A method was developed for the simultaneous determination of 10 triazine herbicides (cyanazine, simazine, simetryn, metribuzin, atrazine, ametryn, terbuthylazine, prometryn, terbutryn, and dimethametryn) in rice samples by high resolution and high mass accuracy hybrid linear ion trap-Orbitrap mass spectrometer. After extraction with acetonitrile and evaporation, the herbicides were redissolved in n-hexane and purified on a Florisil solid-phase extraction column. All compounds were separated within 12 min, producing more than 11 data points for each herbicide and high mass accuracy quantified ions which the mass errors of absolute value were less than 1.9 ppm in pure solution and 2.1 ppm in the matrix-matched standards solution. The method was validated in terms of the limits of detection and the limits of quantification. The linearity was satisfactory, with a correlation coefficient of >0.9975. Precision and recovery studies were evaluated at three concentration levels for Japonica, Indica, and Glutinous rice matrix. The mean recoveries obtained for all analytes in spiked Xiushui 03, Liangyoupeijiu, and Taihunuo rice samples were 83.3–99.0%, 82.0–99.7%, and 84.2–99.4%, respectively, with relative standard deviation in range 1.7–10.6%, 1.2–10.7%, and 1.9–11.6% for spiked rice samples, respectively. The intra-day precision (n = 5) for the 10 herbicides in rice samples spiked at an intermediate level was between 2.8% and 7.9%, and the inter-day precision over 10 days (n = 10) was between 5.5% and 15.9%.

Assessment of Nonnative Invasive Plants in the DOE Oak Ridge National Environmental Research Park  

SciTech Connect

The Department of Energy (DOE) National Environmental Research Park at Oak Ridge, Tennessee, is composed of second-growth forest stands characteristic of much of the eastern deciduous forest of the Ridge and Valley Province of Tennessee. Human use of natural ecosystems in this region has facilitated the establishment of at least 167 nonnative, invasive plant species on the Research Park. Our objective was to assess the distribution, abundance, impact, and potential for control of the 18 most abundant invasive species on the Research Park. In 2000, field surveys were conducted of 16 management areas on the Research Park (14 Natural Areas, 1 Reference Area, and Walker Branch Watershed) and the Research Park as a whole to acquire qualitative and quantitative data on the distribution and abundance of these taxa. Data from the surveys were used to rank the relative importance of these species using the ''Alien Plant Ranking System, Version 5.1'' developed by the U.S. Geological Survey. Microstegium (Microstegium vimineum) was ranked highest, or most problematic, for the entire Research Park because of its potential impact on natural systems, its tendency to become a management problem, and how difficult it is to control. Microstegium was present in 12 of the 16 individual sites surveyed; when present, it consistently ranked as the most problematic invasive species, particularly in terms of its potential impact on natural systems. Japanese honeysuckle (Lonicera japonica) and Chinese privet (Ligustrum sinense) were the second- and third-most problematic plant species on the Research Park; these two species were present in 12 and 9 of the 16 sites surveyed, respectively, and often ranked second- or third-most problematic. Other nonnative, invasive species, in decreasing rank order, included kudzu (Pueraria montma), multiflora rose (Rosa multiflora), Chinese lespedeza (Lespedeza cuneara), and other species representing a variety of life forms and growth forms. Results of this research can be used to prioritize management and research activities related to these invasive taxa on the Research Park as a whole and for specific Natural or Reference Areas. Additional research on the autecology and synecology of each species surveyed is suggested. In particular, research should focus on assessing the impacts of these species on the invaded plant and animal communities and ecosystems. Finally, this ranking system could be used to similarly rank the many other nonnative, invasive species present on the Research Park not included in this study.
