A Fossil Snake (Elaphe Vulpina) From A Pliocene Ash Bed In Nebraska, J. Alan Holman

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A fossil snake from the San tee local fauna was collected in August 1979 by J. Alan Holman, Raymond A. Holman, and Michael R. Voorhies. The Santee local fauna (University of Nebraska State Museum Locality Kx-111) is exposed in a road cut on the south side of the Lewis and Clark Reservoir of the Missouri River, 17.7 km ENE of the junction of the Niobrara and Missouri rivers, Knox County, Nebraska, at Latitude 42° 49' N, 97° 50' W. The matrix of this locality consists of an ash that fell on the area about 4.5 m.y.B.P. during the latter part …

Solitude And Communion In Miau, Eva Margarita Nieto

Spanish Language and Literature Papers

Miau continues to be a challenging work because of the complexity of its problems and techniques. The symbolic title has been studied as a key to the metaphoric tension of both structure and characterization within the novel; Don Ramón de Villaamil's deplorable economic situation reveals the narrator's and the author's critical perception of the false and hypocritical urban society that surrounds him. Above all, his suicide, constructed as it is within a quasi-heretical (certainly not orthodox) interpretation of the mandate of the Almighty, has both fascinated and puzzled critics.² Yet all of these problems, character dehumanization and animalization, the …

Rodrigo Soriano And Galdos: An Uncharted Friendship, Paul C. Smith

Spanish Language and Literature Papers

Since the appearance in 1948 of H. Chonon Berkowitz's PioneeringPerez Galdós: Spanish Liberal Crusader, researchers have slowly been adding new facts to our knowledge of Galdós's life. But measured against major gaps in Berkowitz's information and questionable assumptions he made about Galdós, progress since 1948 towards compiling a reliable and comprehensive corpus of biographical information has been disappointing.

Relationships Between Avifauna And Streamside Vegetation, Evelyn L. Bull, Jon M. Skovlin

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Riparian microhabitats in coniferous forests in northeastern Oregon are sensitive to alteration. They have been used disproportionately by people, livestock, and wildlife. These uses have altered the habitats, specifically by reducing vegetative structure (Thomas 1979).
Land management agencies are revegetating depleted riparian zones to improve fish and wildlife habitat. Managers need information on the response of birds to kinds and structures of vegetation so that wildlife objectives can be met.
Several studies have dealt with the relationships of riparian vegetation and avifauna (Carothers and Johnson 1975, Ferguson et al. 1976, Stauffer 1978). Although these studies determined some of the habitat …

Response Strategies In The Radial Arm Maze: Running Around In Circles, Sonja I. Yoerg, Alan C. Kamil

Papers in Behavior in Biological Sciences

The effects of the size of the central arena on the use of response strategies by rats on an eight~arm elevated maze were examined. The size of the central arena had no effect on accuracy, but the use of adjacent arms increased significantly with a larger central arena, regardless of the size of arena to which rats were first exposed. These results are interpreted in terms of foraging efficiency.

Distribution Ecology: Variation In Plant Recruitment Over A Gradient In Relation To Insect Seed Predation, Svata M. Louda

Svata M. Louda Publications

Although predispersal seed predation by insects is common, no test exists of its effect on plant recruitment. This study examines seed predation in the population dynamics of a native, temperate shrub, Haplopappus squarrosus H. and A. (Asteraceae), over an elevational gradient in the coastal sage scrub vegetation of San Diego County, California, USA. Frequency and abundance of H. squarrosus increase from coast to mountains. Expected abundance, based on flowers initiated, was highest at the coast and lowest in the interior, the opposite of the observed adult plant distribution. Overall flower and seed predation by insects was high (44-73%) and was …

Field Techniques And Research Methods In Geography, Robert Stoddard

Geography Program: Faculty Publications

Inexperienced researchers seeking to solve geographic problems are often confronted with a wide choice of techniques available for acquiring data. Unfortunately, information about these techniques is scattered among various publications. This text was written, therefore, for the purpose of assembling several potential field methods into one publication. It provides aspiring researchers with the opportunity to compare alternative types of data-gathering techniques and to select those appropriate to particular research problems.

Although the emphasis is on research in human geography, the techniques presented are useful for other groups of readers such as urban planners, regional planners, sociologists, and others concerned with …

Protein Synthesis In Rabbit Reticulocytes: Characteristics Of The Protein Factor Rf That Reverses Inhibition Of Protein Synthesis In Heme-Deficient Reticulocyte Lysates, Michael Grace, Robert O. Ralston, Ambica C. Banerjee, Naba K. Gupta

Department of Chemistry: Faculty Publications

During heme deficiency in reticulocyte lysates, the heme-regulated translational inhibitor of protein synthesis (HRI) is activated and shuts off protein synthesis. In partial reactions, HRI phosphorylates the M_r 38,000 subunit (α subunit) of eukaryotic initiation factor 2 (eIF-2), which forms a ternary complex, Met-tRNA_f•eIF-2•GTP. The eIF-2α(P) thus formed is not recognized by two eIF-2 ancillary factors, Co-eIF-2B (which promotes the dissociation of the ternary complex at high Mg²⁺) and Co-eIF-2C (which reverses the inhibition of ternary complex formation), and thus, is presumably inactive in peptide chain initiation. A protein factor, designated RF, which reverses inhibition …

Hysterothylacium Pelagicum Sp. N. And H. Cornutum (Stossich, 1904) (Nematoda: Anisakidae) From Marine Fishes, Thomas L. Deardorff, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Hysterothylacium pelagicum sp. n. from the digestive tract of the dolphin, Coryphaena hippurus, is described from the Atlantic and Pacific oceans. It is most similar to H. cornutum, but differs from it by lacking ventral crests on the males and having the vulva located within the anterior 30-40% rather than 18-25% of the female body. Specimens of H. cornutum are reported from Thunnus albacares, a previously unrecorded host, off Hawaii.

Effects Of Contextual Information On Behavior Of Calidris Sandpipers Following Alarm Calls, Daniel W. Leger, Jami L. Nelson

Department of Psychology: Faculty Publications

Two classes of individuals-signalers and recipients -xist in all animal communication systems (Wilson 1975, Smith 1977). Signals make information available and recipients use this information when "choosing" a response (e.g., Leger and Owings 1978; Seyfarth et al. 1980a, b). Contextual information, which exists outside signals, is also usually available to recipients and may be appraised by them when selecting a response (Smith 1965, 1977). Consequently, to fully understand the responses of recipients we must identify contextual information in addition to signal-conveyed information.

Vertebrate "alarm" signals (signals emitted in the presence of potential predators) may be multi-functional and appear to vary …

The Distribution Of Natural Fractures And Joints At Depth In Crystalline Rock, Donald A. Seeburger, Mark D. Zoback

United States Geological Survey: Staff Publications

This paper presents the results of studies of the natural fracture distribution encountered in 10 test wells drilled in three areas of the United States. Seven of the wells were drilled to depths of 200-250m, while three were drilled to depths of about 1 km. Using an ultrasonic borehole televiewer, fracture depths, strikes, and dips were determined. Steeply dipping fractures were found throughout each of the wells, and in general, few horizontal fractures were observed. Statistically significant fracture pole concentrations were found for each well which were basically invariant with depth, although some variation of fracture orientation with depth was …

Implications Of An Elastic Analysis Of In Situ Stress Measurements Near The San Andreas Fault, A. Mcgarr, M. D. Zoback, T. C. Hanks

United States Geological Survey: Staff Publications

Twenty-nine measurements of in situ stress obtained with the hydraulic fracturing technique near Palmdale, California, are the basis of an elastic analysis of the state of stress in the Mojave Desert adjacent to the San Andreas fault. The measurements were made at depths extending from 80 to 849 m and at distances from the fault between 2 and 34 km. The elastic solution indicates a state of deviatoric stress typical for continents in that the inferred depth gradient of the maximum shear stress is about 7.9 MPa/km. Extrapolation yields an average shear stress in the upper 14 km of the …

Root Development Of Winter Wheat As Related To Tillage Practice In Western Nebraska, Wallace Wilhelm, L. N. Mielke, C. R. Fenster

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Tillage practices can influence crop root development. Root distributions were determined for wheat (Triticum aestivum L.) grown in a wheat-fallow rotation during the 1977-1978 winter wheat crop year on an Alliance silt loam (Aridic Argiustoll). The fallow tillage treatments were plow, subtillage, and chemical (no tillage). Each tillage treatment was split into subplots for N application of 0 or 45 kg/ha.

Rooting density was determined by washing the roots in soil cores 7.6 cm in diam by 15 cm long extracted to depths of 90, 105, and 120 cm on 28 Mar., 2 May, and 8 June 1978, respectively. …

The Ecology Of Mutualism, Douglas H. Boucher, Sam James, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Elementary ecology texts tell us that organisms interact in three fundamen­ tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on. Terms that may be considered synonyms, in whole or part, are symbiosis, commensalism, cooperation, protocooperation, mutual aid, facilitation, reciprocal altruism, and entraide. We use the term mutual­ism, defined as "an interaction between species that is beneficial to both," since it has both historical priority (311) and general currency. Symbiosis is "the living together of two organisms in close association," and …

Second Class Speech: The Court's Refinement Of Content Regulation: Schad V. Borough Of Mount Ephraim, 452 U.S. 61 (1981), David M. Scanga

Nebraska Law Review

This Note examines the United States Supreme Court's prior decisions regarding the doctrine of content regulation and the insights into that doctrine provided by Schad v. Borough of Mount Ephraim. This analysis reveals the difficulty in developing a workable first amendment model for permissible content regulation. While the relationship of first amendment rights to local zoning power is beyond the scope of this Note, an understanding of the Court's theoretical first amendment framework can be particularly relevant to zoning in view of the posture of the Schad and Young v. American Mini Theatres, Inc. cases, which both involved constitutional attacks …

Keynote Address - Wildlife Damage Control And The Cooperative Extension Services, James E. Miller

Great Plains Wildlife Damage Control Workshop Proceedings

Since the establishment of the Extension Service within the United States Department of Agriculture in 1914, in accordance with the mandate of the Smith-Lever Act, Extension personnel have recognized the need and responsibility to provide educational programs to assist clientele both rural and urban. These programs from the "grass roots" level to the Federal level are based on the "long established premise that assisting people with factual, effective and practical educational programs to help them solve problems, evaluate alternatives and make objective decisions, would provide these people with information that would enable them to help themselves. Wildlife damage control was …

Coyote Management: A Rationale For Population Reduction, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

Historic and anecdotal information on coyote depredation and population control is presented, with case histories from specific areas. Population reduction methods, their application and their limitations are described. Situations in which coyote population management is desirable and some of the restrictions imposed by laws and regulations are discussed.

U.S. Fish And Wildlife Service Coyote Control Research, Guy Connolly

Great Plains Wildlife Damage Control Workshop Proceedings

This paper reviews recent research by the Denver Wildlife Research Center, Section of Predator Management Research, on chemical and lethal coyote control methods. Steel trap modifications, aerial shooting, den hunting, the M-44 (spring-loaded sodium cyanide ejector), toxic and nontoxic baits, the toxic collar, other livestock-borne toxicants, development of new toxicants, and aversive conditioning with lithium chloride are discussed. No new, lethal coyote control method has been implemented into practical use over the past decade, but toxic baits and den hunting were lost or banned from use in the Federal-Cooperative Animal Damage Control Program. One new technique, the toxic collar, may …

Prairie Dog Dispersal In Wind Cave National Park: Possibilities For Control, Monte G. Garrett, William L. Franklin

Great Plains Wildlife Damage Control Workshop Proceedings

A study was conducted in Wind Cave National Park, South Dakota, to collect basic information on black-tailed prairie dog (Cynomys ludovicianus) dispersal and to test alternative control techniques. Dispersal occurred during a limited time period in late spring, involved both male and female prairie dogs, and resulted in relatively short movements and poor survivorship. The use of artificial visual barriers to inhibit colony expansion was effective but difficult to apply. The use of diethylstilbestrol as a temporary anti-fertility agent was shown to be an easy and effective method to reduce prairie dog reproduction and decrease colony expansion.

Reducing Coyote Damage To Sheep With Non-Lethal Techniques, Jeffrey S. Green

Great Plains Wildlife Damage Control Workshop Proceedings

Since 1972, when the U.S. Government restricted uses of toxicants for controlling coyotes, a variety of non-lethal techniques has been tested for effectiveness in protecting livestock. Some were ineffective, but others helped to reduce the incidence of predation on sheep. In addition to sound management practices, electric fencing and livestock guarding dogs appear to have the widest applicability for sheep producers. Mechanical frightening devices have been successful in some fenced pasture sheep operations. As with the lethal methods currently used, non-lethal control does not solve all depredation problems. A combination of various control techniques (both lethal and non-lethal) is necessary …

The Immigrant Church As A Symbol Of Community And Place In The Upper Midwest, Robert C. Ostergren

Great Plains Quarterly (through 2013)

There can be little doubt that the church as an institution played a major role in the organization and development of community on nineteenth-century American frontiers, especially in the Middle West. Zealous missionary activity was characteristic of American Protestantism in the nineteenth century, and a good portion of that effort was expended on midwestern frontier populations. Thus the region emerged as a locus of fierce competition between the established American denominations. In addition, the Midwest was fertile ground for the establishment of new denominations. Many who settled the region were immigrants who came directly from Europe. Their uprooting severed ties …

Inhibition Of In Vitro Macrophage Digestion Capacity By Infection With Leishmania Donovani (Protozoa: Kinetoplastida), Gerald F. Kutish, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Promastigotes of Leishmania donovani transformed into amastigotes and survived in cultured macrophages. Promastigotes of Leptomonas costoris, a kinetoplastid parasite of water striders, transformed into amastigotes but did not survive in cultured macrophages. A significant difference in size between the two species of parasitic protozoa allowed development of a bioassay in which the in vitro digestion rate of L. costoris was taken as a measure of macrophage digestive capacity following preinfection with L. donovani. In a 12- to 24-hr period, macrophage cultures infected with the 2S strain of L. donovani retained 50% more L. costoris than did control macrophages …

Review Of Folklore From Kansas: Customs, Beliefs, And Superstitions By William E. Koch, Roger L. Welsch

Great Plains Quarterly (through 2013)

The labor that Bill Koch has put into this volume is heroic. For those of us who study the plains, it is truly a valuable contribution. There are more than five thousand items, maps, tables, charts, and an astonishing inventory of collectors and informants. Each item is documented by sex, age, urban-rural orientation of the informant, and the year the item was collected. I am delighted that this impressive corpus has been made available to us. There is no question but that scholars will long be grateful to Koch for his effort.

Now, anyone who reads book reviews regularly knows …
