An Empirical Bayes Approach To Analyzing Recurring Animal Surveys, Douglas H. Johnson

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Recurring estimates of the size of animal populations are often required by biologists or wildlife managers. Because of cost or other constraints, estimates frequently lack the accuracy desired but cannot readily be improved by additional sampling. This report proposes a statistical method employing empirical Bayes (EB) estimators as alternatives to those customarily used to estimate population size, and evaluates them by a subsampling experiment on waterfowl surveys. EB estimates, especially a simple limited-translation version, were more accurate and provided shorter confidence intervals with greater coverage probabilities than customary estimates.

Accumulation Of Lead And Organochiorine Residues In Captive American Kestrels Fed Pine Voles From Apple Orchards, Rey C. Stendell, W. Nelson Beyer, Robert A. Stehn

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Pine voles (Microtus pinetorum) were collected from pesticide-treated orchards in New York (USA) and fed to three captive American kestrels (Falco sparverius) for 60 days to evaluate potential hazards from soil-borne persistent insecticides. Three control kestrels were fed uncontaminated laboratory mice (Mus musculus). The pine voles contained an average of 38 ppm lead, 48 ppm DDE and 1.2 ppm dieldrin (wet weight). The kestrels accumulated sublethal amounts of lead (1 ppm lead wet weight) in their livers. In contrast, DDE and dieldrin accumulated in the tissues and brains of kestrels to toxicologically significant concentrations. …

Excerpts Of Remarks By Secretary Of Agriculture Clayton Yeutter At His Swearing-In Ceremony In The Usda Patio February 16, 1989, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

Thank you very much ladies and gentlemen. It's a marvelous privilege, pleasure and opportunity for me to be here this morning. As I look out over this audience I see a multitude of long-time friends and I am so pleased and gratified that all of you were willing to take time out of your hectic and demanding schedules to be here and share this occasion with us.

Remarks By The President At Swearing-In Ceremony Of Secretary Of Agriculture Clayton Yeutter, Clayton K. Yeutter

Clayton K. Yeutter, United States Secretary of Agriculture: Papers

THE PRESIDENT: Thank you, Peter, and all the members of the Cabinet; the members of the United States Congress here; distinguished ambassadors and others. I've come over here today for the swearing-in of our Secretary. Clayton Yeutter is about to make an enduring commitment to this Department and I should acknowledge the fact that I think five of his predecessors are here today -- Democrats and Republicans which I think gives him an extraordinarily good send-off. There's a difference, you know, between involvement and commitment. You all know it. Remember the old farmer making eggs and bacon. The chicken is …

Bluestem Seed Midge Influence On Sexual Reproduction Of Big Bluestem: A Review, K. P. Vogel, G. R. Manglitz

Proceedings of the North American Prairie Conferences

A Cecidomyiid midge (Contarinia wattsi Gagne') has been identified as a significant parasite of big bluestem [Andropogon gerardii Vitman var. gerardii] by adversely affecting the production of viable seeds. The midge was first identified from specimens collected from big bluestem racemes in 1983 in eastern Nebraska. Subsequent collections and studies have shown that it is widespread in the Great Plains, and that it can reduce seed yields of big bluestem by over 40%. The midges apparently over winter as diapausing larvae in disarticulated spikelets, emerge as adults at the time of early panicle emergence, and lay their …

An Essay On The Concept Of Demonstration Rooftop Prairies, Patrick Horsbrugh

Proceedings of the North American Prairie Conferences

The concept of demonstration prairies on the roofs of industrial and commercial premises is recommended as a means of stimulating interest in prairie ecology and of providing educational facilities in urban areas. The economics of such rooftop locations for prairie studies and research depends upon the multiple use of land for seemingly incompatible activities. The use of selected vegetation as an integral part of the structure provides the opportunity for the prairie to invade the city, while potentially offering the benefits of effective insulation, microclimatic modification, and reductions in roof maintenance costs. This would be one method to meet the …

51-Year Change In The Shortgrass Prairie Of Eastern Wyoming, Herbert G. Fisser, Kendall L. Johnson, Kellie S. Moore, Glenn E. Plumb

Proceedings of the North American Prairie Conferences

In 1936, vegetation analyses were conducted on repurchased federal lands in the Powder River Basin of eastern Wyoming. During the summer of 1987 the 74 remaining plots of 97 originally established on a 2.6 km² (1 mi²) area in Converse County were re-examined. Both surveys were conducted with the "square foot density procedure." During the past 51 years, vegetation abundance increased significantly on the saline upland site as a result of the interactive effects of favorable long-term weather patterns, annual grazing by livestock and wildlife, and reduced fire. Total vegetation cover increased significantly (P < 0.05) from 3% in 1936 to 11 % in 1987, including a threefold increase for all grasses and a fourfold increase for all woody species. A negligible change occurred for all forbs. A shift in the cover composition occurred with grasses decreasing from 52% to 44% and non-grass species showing a corresponding increase. All growth forms, except shrubs, gained wider distribution over the study period, especially succulents and annual grasses. Continuation of current management practices probably means that this range will not return to a short grass-dominated prairie.

Do You Know Platanthera Praeclara?, Rochelle Bjugstad, Ardell J. Bjugstad

Proceedings of the North American Prairie Conferences

This is a brief synthesis on the plant, habitat and range of the western prairie fringed orchid (Platanthera praeclara Sheviak and Bowles). This species was once common in the tall grass prairie, but its numbers have been greatly reduced by improper management and loss of habitat. Comparisons are made to the eastern prairie fringed orchid [Platanthera leucophaea (Nutt.) Lindl].

Seasonal Activity Of Snakes On A Sand Prairie, Dwight R. Platt

Proceedings of the North American Prairie Conferences

Snakes were caught in drift fence traps throughout the season of activity on a 32 ha sand prairie in Harvey County, Kansas, from 1966 through 1974. In these nine seasons, 128,281 trap station days yielded 6,412 captures of the six most common species of snakes: Pituophis melanoleucus sayi, Coluber constrictor jlaviventris, Thamnophis sirtalis parietalis. Thamnophis radix haydeni, Heterodon nasicus, and Heterodon platirhinos. Seasonal activity patterns, although variable from year to year, had a bimodal pattern with a period of low activity in late July or late August. Increases in snake activity resulted from increases in population size due …

Rhizome And Tiller Development Of Three Nebraska Sandhills Warm-Season Grasses, John J. Brejda, Lowell E. Moser, Steven S. Waller

Proceedings of the North American Prairie Conferences

Rhizome and tiller development of ungrazed switchgrass (Panicum virgatum L.), prairie sandreed [Calamolvilfa longifolia (Hook) Scribn.], and sand bluestem [Andropogon gerardii var. paucipilus (Nash) Fern.] were studied for two years in the Nebraska Sandhills. Rhizome growth of switchgrass began at the 4- to 5-leaf stage. Following tiller elongation, no new rhizomes developed but rhizome elongation continued. Many of the prairie sandreed tillers were biennial similar to those of indiangrass [Sorghastrum nutans (L.) Nash]. Spring tiller development on prairie sandreed came from both vertical and horizontal rhizomes and continuing growth of late emerging tillers from the previous year. …

Plant Species Composition And Groundwater Levels In A Platte River Wet Meadow, Paul J. Currier

Proceedings of the North American Prairie Conferences

Species composition was monitored in seven permanent exclosures at Mormon Island Crane Meadows, near Grand Island, Nebraska from 1982 to 1987. Crane meadows is a 1,050 ha (2,600 acre) native lowland prairie complex with a corrugated topography of wetland swales and dry sand ridges. Variable precipitation, periodic over-bank flooding, and river stage fluctuations complicate the system's hydrology. In general, springs are wet, but, by late summer, the meadows are usually dry, closely paralleling river flows and precipitation patterns. A sustained high water period in 1983 and 1984 was responsible for major changes in species abundance. Plant responses were consistent with …

Long-Term Grass Dynamics Within A Mixed-Grass Prairie, Brian S. Mihlbacher, Fred E. Smeins, Gerald W. Thomas, Charles A. Taylor

Proceedings of the North American Prairie Conferences

Western portions of the Edwards Plateau are dominated by a grass mosaic which consists of a rhizomatous midgrass, tobosagrass [Hilaria mutica (Buckl.) Benth.], and two stoloniferous short grasses, common curlymesquite [Hilaria belangeri (Steud.) Nash] and buffalograss [Buchloe dactyloides (Nutt.) Engelm.]. Permanent 0.3 m x 6 m belt transects were established on three major soil series (Tobosa, Ozona. Valera) across several grazing treatments on the Texas Range Station near Barnhart, Texas, and the distribution of perennial grasses was mapped in 1951 (pre-drought), 1953 (drought), 1957 (post-drought), and 1987. Cover showed no consistent trends in relation to grazing. Total …

Small Mammals Of A Relict Wet Prairie In Ohio, Eric D. Osborn, Carl W. Hoagstrom

Proceedings of the North American Prairie Conferences

Killdeer Plains is a Wildlife Area in northwest Ohio managed primarily for waterfowl. At the turn of the century, the area was a wet prairie remnant of the prairie peninsula. Despite attempts at drainage and farming, parts of the area retain the characteristics of a wet prairie. Two spruce-pine (Picea - Pinus) clumps in the plains are used as winter roosts by long-eared owls (Asio otus). Pellets regurgitated by these owls were examined to determine the species and relative numbers of small mammals in the area. Nearly 90% of all individuals taken by the owls were …

Small Bison Herd Utilization Of Tallgrass Prairie, Lorence Larson, G.K. Murdock

Proceedings of the North American Prairie Conferences

The utilization of a tall grass prairie remnant by a small bison (Bison bison) herd is described. Three bulls and six cows were introduced to a 257 ha section of Prairie State Park, Liberal, Missouri in 1985. Between 1985 and March 1988, ten calves were born; four cows and a bull were introduced to the herd in 1988. Since March 1986, the behavior of the herd has been observed three times per week, year-round. The portion of the herd using mowed fire breaks or burned or unburned portions was determined at ten-minute intervals; for 3,249 observations over 213 …

The Western Prairie Fringed Orchid (Platanthera Praeclara): Monitoringa And Research, Ardell J. Bjugstad, William Fortune

Proceedings of the North American Prairie Conferences

Western prairie fringed orchid (Platanthera praeciara Sheviak and Bowles) populations at one time extended from southwestern Missouri north to northwestern Minnesota, and from eastern Iowa to the Sandhills of north central Nebraska. It is listed as endangered in Iowa and Minnesota and candidate for threatened or endangered status in Kansas, Missouri, Nebraska, North Dakota, Oklahoma, and South Dakota. The questions are, "Why has it declined in numbers?" How have uses such as mowing for hay or grazing by cattle or no use (control) affected the numbers? In 1987, permanently located individual plants were counted on the Sheyenne National Grasslands …

Tallgrass Prairie Remnants Of Eastern Nebraska, Judith F. Boettcher, Thomas B. Bragg

Proceedings of the North American Prairie Conferences

Ten eastern Nebraska tallgrass prairie remnants were evaluated up to four times during the 1979 growing season to assess vegetative composition and the effects of mowing, topographic and size differences, and season of evaluation. Frequent mowing resulted in a reduced canopy cover of some species, such as big bluestem (Andropogon gerardii Vitman) (21% lower with frequent mowing), but increased cover of others, particularly the introduced species smooth brome (Bromus inermis Leyss. subsp. inermis) (35% higher cover with frequent mowing). In addition, frequent mowing resulted in a higher proportion of disturbance species. Comparing the time of mowing, canopy …

This document describes the early history of the Federal Government technical reports distribution system. The Office of Technical Services has evolved into the National Technical Information System.

Digitized by Robert L. Bolin

US information policy during the post-World War II era reflected a duality of purpose: gain international superiority in the science and technology sectors, and promote the flow of such information to small business in America. To accomplish these dual purposes, Congress and the administration cooperated to create and fund the Office of Technical Services. OTS's job was to communicate the enormous body of scientific and technical research undertaken …

Early Childhood Special Education In The Next Decade: The Impact Of Public Law 99-457 In Nebraska, Deana Finkler, Cordelia Robinson

Center for Public Affairs Research (UNO): Publications

Nebraska has served handicapped children from birth to age 21 through special education and other services since 1978. But in 1991 Public Law 99-457 will include federal funding for preschool services and incentive grants for infants and toddlers. Because Nebraska has already been serving these populations, it will not receive new funds under the new law. States that will be taking advantage of the incentive funds will be looking to Nebraska-and other states with experience in serving handicapped infants and preschoolers-for precedence. Although under P.L. 99-457 policy has been set at the federal level, key state policy considerations remain. These …

Nebraskans And Educational Pluralism, Helen A. Moore

Center for Public Affairs Research (UNO): Publications

Equality of educational opportunity continues to be a goal of public education and of the communities served. To meet the diverse needs of racial and ethnic minorities and female students, policy makers must untangle layers of government guidelines, while attending to the goals of local constituents.

The under-representation of minorities among public school graduates, and gender and race inequality in school teaching and administrative staffs, are discussed in this chapter. Community attitudes toward pluralistic goals and integration in education are highlighted, and suggestions are made for coordinating the diverse needs of all students.

Cognitive Processes In The Curry Learning Style Framework As Measured By The Learning Style Profile And The Myers-Briggs Type Indicator Among Non-Majors In College Biology, Claudia Tarver Melear

Department of Agricultural Leadership, Education and Communication: Dissertations, Theses, and Student Scholarship

Curry's (1983) model of learning style framework with Claxton & Murrell's (1987) adaptations was used to study the profile of the non-major in a college biology course. The purpose of the study was to provide empirically derived data in both a qualitative and quantitative format of the non major (both successful and unsuccessful students) to improve the course. Over 600 students were administered the Learning Style Profile [(LSP) (National Association of Secondary School Principals) Indicator (MBTI) (NASSP) and the Myers-Briggs Type (Consulting Psychologists Press)] to determine the students' learning styles as a predictor for Success in the course. The MBTI …

Library Vendors: How Do They Use Us?, Kent Hendrickson

UNL Libraries: Faculty Publications

I must assume that I was asked to talk on the topic of "Library Vendors: How Do They Use Us?" because I have spent a portion of my professional career on either side of the issue--12 years as a librarian and 11 years with Abel and then Blackwell North America (B/NA). With that in mind, I think my speech could also be titled, "Librarian at Risk." I came here with many friends, librarians, subscription agents and book sellers, and may leave with few or none.
