Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter Dec 1981

Intraisland And Interisland Variation In Antillean Populations Of Molossus Molossus (Mammalia: Molossidae), Hugh H. Genoways, Robert C. Dowler, Catherine H. Carter

University of Nebraska State Museum: Mammalogy Papers

Significant levels of secondary sexual variation and expected levels of individual variation were demonstrated in all samples of Molossus molossus from Jamaica, Guadeloupe, and Trinidad examined with univariate analyses. Significant morphometric differences were demonstrated among samples of Molossus molossus that originated from geographically close localities on the same island. Using multivariate techniques, broader patterns of geographic variation were demonstrated among the Antillean populations of M. molossus.


Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways Dec 1981

Distribution And Taxonomic Status Of Blarina Hylophaga Elliot (Insectivora: Soricidae), Sarah B. George, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Systematic relationships of southern populations of short-tailed shrews (genus Blarina) are assessed on the basis of univariate and multivariate statistics. Populations are separated into two phena; southwestern short-tailed shrews are significantly larger morphometrically than southeastern forms. The two phena apparently represent distinct species. The name Blarina hylophaga is available for southwestern populations, and the name Blarina carolinensis is here restricted to short-tailed shrews in the southeastern United States.


Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways Dec 1981

Systematic Review Of The Texas Pocket Gopher, Geomys Personatus (Mammalia: Rodentia), Stephen L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The Texas pocket gopher (Geomys personarus), which occupies a range in southern Texas and extreme northeastern Tamaulipas, was examined for morphological variation. Univariate and multivariate analyses were used to determine age, secondary sexual, individual, and geographic variation. Significant differences were found among the three age classes and between the sexes for 12 of 13 cranial measurements. Males displayed higher individual variation than females. Distributions of the six previously recognized subspecies (fallax, fuscus, maritimus, megapotamus, personatus, and streckeri) were examined. An additional subspecies is recognized and described. Of the seven subspecies of …

1981 Fall Field Day

Nebraska Bird Review

About forty people participated in the 1981 Fall Field Day, which was scheduled from noon Saturday 3 October to noon Sunday 4 October, but which was anticipated by early arrivals Friday and on Saturday morning. The weather was windy and cool, the skies overcast much of the time, with some rain Saturday afternoon, and Sunday morning overcast so that it was hard to get colors. But almost as soon as the meeting broke up Sunday noon the sky cleared and everybody went home in bright sunshine. There was a slide show Saturday night. Of the reports on unusual species, submitted …

Nebraska Bird Review

DIXON COUNTY. In mid-March 1981 there were thousands of Snow Geese on the Missouri near Ponca, also Canadas, and we saw 6 White-fronteds up close in a plowed field. We also saw lots of ducks: Pintails, Ring-necks, Redheads, Mallards, and others. We saw Field Sparrows, and in town White-breasted Nuthatches, Robins, and Starlings were everywhere.

Influence Of Crop Residue Removal On Yields Of Corn, Sorghum, And Soybeans With No Tillage, J. W. Doran Nov 1981

Influence Of Crop Residue Removal On Yields Of Corn, Sorghum, And Soybeans With No Tillage, J. W. Doran

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

For 3 years, yields were significantly influenced by amount of crop residue on the soil surface. Where surface crop residues were completely removed, average yields of corn, sorghum, and soybeans were 24, 6, and 27% lower than where residues were not removed. Removal of 50% surface crop residues had little or no effect on yields. Yield reductions were directly related to higher soil and plant canopy temperatures and lower soil water contents where surface crop residues were removed.


An X-Y-Plotter-Based Technique For Measuring Root Length, Wallace Wilhelm, J. M. Norman, J. R. Ellis, R. L. Newell Nov 1981

An X-Y-Plotter-Based Technique For Measuring Root Length, Wallace Wilhelm, J. M. Norman, J. R. Ellis, R. L. Newell

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

Several automated systems have bee reported which use modifications of the line-intersect method to accurately estimate root length; however, most of these systems are relatively expensive to construct. The system described here employs an X-Y plotter, a 2 x 2 slide projector, and a fiber optic photodiode to determine intersections between projected images of a root system and grid pattern traced by the light sensor, which is mounted in the pen of the X-Y plotter. With adequate shielding to eliminate false counts, the system reproduced manual counts (r2=0.9999) for white sewing thread, carpet thread, and 0.14-mm-diam. wire. When …


Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways Nov 1981

Electrophoretic And Immunological Studies On The Relationship Of The Brachyphyllinae And The Glossophaginae, Robert J. Baker, Rodney L. Honeycutt, Michael L. Arnold, Vincent M. Sarich, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla from Phyllonycteris are in the general range of values that characterize congeneric species of mammals. Immunological distance values for the species Glossophaga soricina, Monophyllus redmani, Anoura caudifer, Leptonycteris sanborni, Choeroniscus minor, and Hylonycteris underuoodi indicate that these taxa are approximately equidistant from the Brachyphyllinae. Immunological comparisons of Glossophaga and Monophyllus to Anoura, Leptonycteris, Choeroniscus, …

Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker Oct 1981

Mice Of The Genus Peromyscus In Guadalupe Mountains National Park, Texas, John E. Cornely, David J. Schmidly, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

Mice of the genus Peromyscus are found in virtually every habitat type in Guadalupe Mountains National Park in West Texas. Because of their abundance and wide distribution, they comprise an important component of the park's ecosystem. The first known specimens of Peromyscus from the area now included in the park were collected by Vernon Bailey in 1901 (Bailey, 1905). He collected specimens of Peromyscus boyIii in Dog and McKittrick canyons. Davis (1940) collected P. leucopus at Frijole in 1938 and P. boylii in The Bowl in 1938 and 1939. Davis and Robertson (1944) reported collecting P. pectoralis from along Bell …


Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech Oct 1981

Dynamics, Movements, And Feeding Ecology Of A Newly Protected Wolf Population In Northwestern Minnesota, Steven H. Fritts, L. David Mech

USGS Northern Prairie Wildlife Research Center

The gray wolf Canis lupus occupies only about 1 percent of its former range in the lower 48 states (Mech 1974a). Most of the range is in northern Minnesota, where the resident population is classified as "threatened" by the U.S. Department of the Interior. Wolves have been and will continue to be the subject of considerable controversy in Minnesota.

The first scientific study of wolves in Minnesota was conducted by Olson (1938a,b). That and all subsequent re- search was in the Superior National Forest (SNF) of northeastern Minnesota even though wolves inhabit approximately the northern third of the state. Consequently, …

A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler Oct 1981

A Forecasting-Programming Method For Swine Production-Marketing Decisions, Larry Janssen, James B. Hassler

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This study reports on the development and progress of a forecasting-programming model for swine inventory management and marketing decisions. This model considers interrelationships between breeding herd, feeder pig and finishing hog activities. Objectives were: 1. To structure a dynamic operational decision model for a modern farrow-to-finish swine confinement unit which conforms with economic theory, uses price and cost forecast information and is as consistent as possible with current production scheduling practices. 2. To use and test this model during a combined production and marketing decision process and to compare economic results with results of a standard strategy.


Results Of The Third High Protein-High Lysine Wheat Observation Nursery Grown In 1977, S. L. Kuhr, V. A. Johnson, P. J. Mattern, K. D. Wilhelmi Oct 1981

Results Of The Third High Protein-High Lysine Wheat Observation Nursery Grown In 1977, S. L. Kuhr, V. A. Johnson, P. J. Mattern, K. D. Wilhelmi

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third report of results from a high protein-high lysine (HP-HL) wheat observation nursery organized in 1974 by the Nebraska Agricultural Experiment Station and the Science and Education Administration, U.S. Department of Agriculture, under a contract with the Agency for International Development, U.S. Department of State. Advanced experimental lines distributed to breeders and cooperators in the 3rd HP-HL nursery were selected from numerous hybrid combinations of both spring and winter types. All exhibited elevated protein and/or lysine in nursery trials in Nebraska or Arizona.

GREAT-TAILED GRACKLE. The note on Great-tailed Grackles at Columbus (NBR 49:28) incorrectly described them as "nesting"; Prof. Holtz's report said only "a pair of Greattailed Grackles". This error apparently came from overloading memory before typing in transcribing the report.

CHASE COUNTY. Iola Pennington, Wauneta, made five reports on her observations at Wauneta, Enders Reservoir, and Champion from 25 February to 26 April 1981. The birds on the first report had been there earlier, and except for the last report only the more notable species were reported: Geese: Canada 2/25, Snow 4/2; Mallard 2/25-4/26, Gadwall 3/27, Pintail 2/254/ 2; Teal: Green-winged …

Heritability Estimates For Forage Yield, In Vitro Dry Matter Digestibility, Crude Protein, And Heading Date In Indiangrass, K. P. Vogel, Herman J. Gorz, Francis A. Haskins Sep 1981

Heritability Estimates For Forage Yield, In Vitro Dry Matter Digestibility, Crude Protein, And Heading Date In Indiangrass, K. P. Vogel, Herman J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Space-planted populations derived from 'Holt' and 'Oto' indiangrass, Sorghastrum nutans (L.) Nash, were used to obtain heritability estimates for forage yield, in vitro dry matter digestibility (IVDMD), crude protein, and heading date and to determine their genotypic correlations. Heritability estimates were determined by variance component analyses and by parent-progeny regression. Average narrow sense heritability estimates for the two populations were 0.43, 0.42, and 0.50, for forage yield, IVDMD, and protein, respectively. Narrow sense heritability estimates for heading date were 0.90 or larger. Genotypic correlations of yield and IVDMD were negative for the Holt population but were positive, although low, for …

Information on the Norfolk Christmas Count was received after the tabulation was published (NBR). The count was taken 20 December 1980 from 7 AM to 5:30 PM, temperature was from -1 ° to 15° F, and wind from the south at 8 mph. The count was centered on the intersection of US 275 and US 81 (13th Street and Norfolk Avenue). Since the 15 December 1979 count was not included in the 1979 tabulation (NBR 48:15) it is also included (the first figure is for 1979).
