Systematics Of Southern Banner-Tailed Kangaroo Rats Of The Dipodomys Phillipsii Group, Hugh H. Genoways, J. Knox Jones Jr.

University of Nebraska State Museum: Mammalogy Papers

Both nongeographic and geographic variation was assessed in southern banner-tailed kangaroo rats of the nominal species Dipodomys phillipsii and D. ornatus . Univariate and multivariate analyses were employed in consideration of geographic variation. D. ornatus is arranged as a subspecies of D. phillipsii, in which four races (phillipsii, ornatus, perotensis, and oaxacae) are recognized. Some observations on natural history also are included.

The Gonads Of The South American Dolphins, Inia Geoffrensis, Pontoporia Blainvillei, And Sotalia Fluviatilis, Richard J. Harrison, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The appearances of the gonads are described in males and females of 18 Inia geoffrensis, 11 Pontoporia blainvillei, and eight Sotalia fluviatilis from South America. Males of I. geoffrensis become sexually active at a length of about 228 centimeters, females at 175 to 180 centimeters. Length at birth is 76 to 80 centimeters; parturition occurs from about July to September in the upper Amazon. Males of P. blainvillei are still sexually immature at a length of 128.5 centimeters, females become sexually active at a length of 137 centimeters. Off Uruguay, pregnant females have fetuses 6 centimeters in length …

Type Appraisal: Ii. Variation In Type Traits Due To Sires, Herds, And Years, H. D. Norman, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Variance components were estimated from type appraisal data to determine the importance of year, herd, sire, and herd x sire effects upon 49 body, udder, and management traits. Estimates were based on over 16,000 appraisals on daughters of Holstein artificial insemination sires. The variation explained by these effects never exceeded 34% of the total variance. Year effects were almost nonexistent (-2 to 3%). Herd effects were small for all traits except feeding speed, body weight, intensity and persistency of edema, and ketosis, and never exceeded 25%.

Most appraisal traits had low heritabilities. The estimate for milking speed was .23 while …

Type Appraisal: I. Effects Of Age And Stage-Of-Lactation On Type Ratings, H. D. Norman

Department of Animal Science: Faculty Publications

Dairy cattle type appraisal data were examined to determine whether body and udder conformation and management ratings were affected by age and period of lactation at appraisal. Data were collected from 1961 to 1968 from 188 herds having over 23,000 Holstein type appraisals. The body and udder traits were scored by scheduled appraisers, and the management traits were coded by each dairyman. Some of the 35 original traits were composed of more than one descriptive characteristic and, as a result, 49 renamed traits were derived from these.

A model was selected that considered years and herds as well as cow …

Type Appraisal: Iii. Relationships Of First Lactation Production And Type Traits With Lifetime Performance, H. D. Norman, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Phenotypic and genetic correlations were estimated between 48 type appraisal traits and first lactation milk production to determine the importance of appraisal traits in a breeding program from 5,024 records from the New York type appraisal program. Most phenotypic correlations among the type traits were near zero. Depth of udder was the appraisal trait having the highest correlation with first lactation milk (.27) and fat (.23). Multiple correlations of all appraisal traits with first lactation milk and fat were .44 and .40.

Correlations with lifetime variables were calculated from 2,068 records meeting time qualifications. Of the first lactation variables, milk …

Second-Order Pulsations In Polytropes, Norman R. Simon

Norman R. Simon Papers

A theory due to Eddington is employed to calculate second-order corrections to the usual linear, quasi-adiabatic pulsational amplitudes. Such corrections are necessary in order to evaluate the pulsational stability of stars in thermal imbalance (dS₀/dt ≠ 0). The second-order quantities are calculated, and their properties discussed, for a wide variety of polytropic models. Subsequently, a number of these models are tested for pulsational stability, and the conclusions drawn in an earlier, more preliminary work are re-evaluated on the basis of the results. In particular, it is found that stars in pre-main-sequence contraction are probably stable against …

Micrographs of energetic particles in nuclear emulsion are simulated by computing the spatial distribution of developed grains with the δ-ray theory of track structure, and representing the developed grains by points of light on an IBM 2250 visual display unit. The simulated tracks display many of the features of actual track structure and serve as a visual comparison between experiment and theory,

Morphological Variation In Stenoderma Rufum, J, Knox Jones Jr., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

For more than 100 years, the red fruit-eating bat, Stenoderma rufum Desmarest, 1820, was known only by a specimen of unknown geographic provenience. Anthony ( 1918, 1925) rediscovered Stenoderma in Puerto Rican cave deposits, but the first living specimens to be reported since the original description were taken on St. John in the Virgin Islands (Hall and Bee, 1960). Subsequently, Tamsitt and Valdivieso (1966) recorded living representatives from Puerto Rico-from a population later named and described as a distinctive subspecies, Stenoderma rufum darioi, by Hall and Tamsitt (1968). The latter authors also reported a specimen of S. r. rufum …

Genetic And Environmental Aspects Of Udder Infections, J. W. Wilton, L. Dale Van Vleck, R. W. Everett, R. S. Guthrie, S. J. Roberts

Department of Animal Science: Faculty Publications

Information on the presence or absence of bacterial infections and abnormal secretions in each quarter of cows in their initial survey on the New York State Veterinary College Mastitis Program was used to obtain several criteria of udder infection. Year-season and stage of lactation effects were statistically significant for several criteria of infection in first, second, and later lactation groups but did not explain much of the variation in any infection criterion. Age within first and second lactation group also accounted for little of the variation in infection although age within later lactations accounted for up to 5% of the …

A Study Of Primary Productivity In A Nebraska Interstate 80 Lake, Gilbert Adrian, Carl Throckmorton, Bob Mcdonald

Nebraska Game and Parks Commission: Staff Research Publications

The primary productivity of a small gravel pit lake in the Platte River Valley of Nebraska was studied for a 2-year period. Daily production rates were estimated from near weekly samples, with calculations done by computer. Emphasis was placed on production under ice during winter conditions. Annual production was estimated and is compared with several other lakes in North America.

Wing Loading In Plecotus Rafinesquii, Clyde Jones, Royal D. Suttkus

United States Fish and Wildlife Service: Publications

Considerable interest has developed in recent years with regard to studies of wing areas and wing loadings of North American bats (Davis and Cockrum, 19645; Jones, 1967; Davis, 1969; Farney and Fleharty, 1969). To our knowledge, such data have not been presented for Plecotus rafinesquii, one of the least known of North American species (Barbour and Davis, 1969). The purpose of this report is to provide information on flight of P. rafinesquii species, as well as adults of two other species of Plecotus.

Seventy-one P. rafinesquii were studied: five were banded and released and 66 were preserved either as skins …

Introduction To Ethnic Voters And The Election Of Lincoln, Frederick C. Luebke

Department of History: Faculty Publications

A twofold purpose informs this anthology of essays on ethnic voters in the presidential election of 1860. First, it gathers together a great quantity of factual information about immigrants and politics on the eve of the Civil War. Naturally, the Germans receive the greatest amount of attention. Not only did they rival the Irish in numbers in 1860. but they were also the most diverse ethnic group in America. The essays of this volume also offer much data about politicians and their perceptions of the democratic process, about political parties and the social bases of their support, and about political …

The Occurrence And Significance Of Polychlorinated Biphenyls In The Environment, E.H. Dustman, L.F. Stickel, L.J. Blus, W.L. Reichel, S.N. Wiemeyer

United States Fish and Wildlife Service: Publications

The natural world today contains a vast array of man-made chemicals, many of them with biological potency in quantities scarcely measurable tow decades ago. Wild animals encounter these chemicals in multifold combination, but man's knowledge of their effects on wild species progresses haltingly. While research focused on DDT, dieldrin, and related chemicals that were obvious suspects for cause of environmental problems, other compounds, some unidentified, spread and increased.

Polychlorinated biphenyls (PCB's) constitute one such group. PCB's are products of modern industrial chemistry that have escaped to the environment by routes still largely unknown. They have become ubiquitous in the world …

Effects Of Thiabendazole Treatment On Weight Gains By Nebraska Range Cattle, D. L. Ferguson, D. A. Reynolds, M. J. Twiehaus

School of Veterinary and Biomedical Sciences: Faculty Publications

The results of these studies indicate that a high percentage of Nebraska range cattle are infected with gastrointestinal parasites, but at a subclinical level of infection. However, significant differences were not observed in average daily gain between thiabendazole-treated range cattle and unmedicated controls in three of four field trials. In the three trials the average improvement in daily gain in animals receiving thiabendazole once averaged .01 lb greater than untreated controls. During a 120 day grazing period this improvement would not be sufficient to pay for the wormer or cost of additional labor.

A Bibliography Of The Aboriginal Archeology Of Nebraska, Donald J. Blakeslee

Nebraska Anthropologist

I have tried to make this Bibliography as complete as possible, including material from surrounding states pertinent to the archeological problems of Nebraska and references which pertain more to the history of Nebraska archeology than to its content.

In compiling this list, I have used previous bibliographies by Robert W. Neuman (1962b, 1968) and Jerome E. Petsche (1968) which deal in part with Nebraska archeology.

Franchise Full Disclosure, Terry D. Sattler

Nebraska Law Review

Although there is no "typical" franchise contract, the franchise purchaser, or franchisee, is usually required to pay a fee for the privilege of opening a franchise outlet, and must then rely upon the franchise seller, the franchisor, to provide guidance and support in the operation of the enterprise. If the venture fails, the franchisee may lose his entire investment. In the past, there have been attempts to regulate substantive provisions of franchise agreements in order to reduce the instances of investment loss by franchisees. The focus of recent concern over franchising practices has not involved the objection to particular contract …

Cheating As A Function Of The Labeling Of Natural Arousal, Richard A. Dienstbier, Pamela Osbourne Hunter

Department of Psychology: Faculty Publications

One hundred and five college freshmen were given one of two different side-effects lists associated with a placebo pill. In a “second” experiment, subjects experienced failure on a vocabulary test, supposedly predictive of college success, and received an opportunity to cheat on the test by changing answers. Although it was anticipated that all subjects who considered cheating would experience some arousal, it was predicted that those subjects told to expect drug-induced side effects related to sympathetic arousal would not label their experienced arousal as fear or guilt, and would cheat more than the subjects who anticipated benign side effects. Of …

The Effect Of Stimulus Element Redundancy On Speed Of Discrimination As A Function Of State And Process Limitation, John H. Flowers, W. R. Garner

Department of Psychology: Faculty Publications

The effect of spatially repeated stimulus elements on the speed of discrimination, measured in a sorting task, was determined under conditions of low stimulus visibility (state limitation) and high stimulus similarity (process limitation). A significant increase in speed of sorting stimuli was found when the stimuli were state limited but not when process limited, even though base speeds were the same in both cases. It is concluded that element redundancy will improve discrimination performance only when the need for the improvement is a state limitation.
