Leaf Freckles And Wilt Of Corn Incited By Corynebacterium Nebraskense Schuster, Hoff, Mandel, Lazar, 1972, M. L. Schuster

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The new bacterial disease Leaf Freckles and Wilt (LFW) of corn (Zea mays L.) was first observed in 1969 on two farms in southcentral Nebraska. Since then it has spread to other areas in the state. LFW is a serious disease on farms in six Nebraska counties (Clay, Custer, Dawson, Furnas, Hall and Phelps) and has been found in isolated cases in at least 28 other counties. In 1971 LFW was found in a seedcorn field in western Iowa, in 1973 in two Kansas counties, and in 1974 in South Dakota and Colorado. Because of its explosive nature, several …

Rbe-Dose Relations For Neutrons And Pions, Robert Katz, S. C. Sharma

Robert Katz Publications

RBE-Dose relations have been calculated from cellular radiosensitivity parameters and theoretical particle-energy spectra in tissue, of the secondary particles from neutron and negative pion irradiations. The theoretical results are compared with clinical and radiobiological data for normal tissue, tumors, and cells in culture. Formulae for calculation, cellular parameters, and the needed properties of equivalent “track-segment bombardments” are given, for several mammalian cells irradiated with pions and with neutrons of several energies.

Collections Of Recent Mammals In North America, Jerry R. Choate, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Mammalogy is the only systematic discipline that has previously undertaken periodic (that is, more than one) surveys of its holdings in North American collections. The first such survey (reported on by Howell, 1923) pertained to mammals in collections as of April of 1922. The report of the second survey (Doutt et al., 1945) summarized collections of mammals in North America as of 1943. The report of the third survey (Anderson et al., 1963) pertained to specimens of mammals in North American collections as of 1962. At that time, it was assumed that to prepare an updated report on North American …

A New Subspecies Of Geomys Bursarius (Mammalia: Geomyidae) From Texas And New Mexico, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

As part of a study of the systematics and ecology of pocket gophers occurring on the high plains of Texas and eastern New Mexico, numerous populations of the plains pocket gopher, Geomys bursarius, were examined karyotypically. Four chromosomal races were described from this area by Baker et al. (1973). Additional studies lead us to believe that two of these races represent an undescribed subspecies of the plains pocket gopher. In addition to karyological evidence, specimens of this subspecies are morphologically distinct from those of all contiguous populations of Geomys bursarius major, the race to which they previously were assigned. …

Mammals Of The Guadalupe Mountains National Park, Texas, Hugh H. Genoways, Robert J. Baker, John E. Cornely

University of Nebraska State Museum: Mammalogy Papers

Our survey began in late May 1973 and continued through August 1975. The objectives of our study, which was supported by the National Park Service, were to survey the mammals occurring in the Guadalupe Mountains National Park, Texas, and to correlate their distribution with major plant associations. This inventory of the natural resources of the park is preliminary to the development of any serious management program. Therefore, we present the following accounts to serve as baseline data for future mammalian work in the park and development of the master plan for the park.

Editors' Note To Biological Investigations In The Guadalupe Mountains National Park, Texas., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The Guadalupe Mountains National Park, which is located in TransPecos Texas between Carlsbad, New Mexico, and EI Paso, Texas, is one of the newest national parks being formed by the Congress in 1967. The Guadalupe Mountains and the associated Chihuahuan Desert included in the park represent a unique biological area in which a fragile biological equilibrium exists between the fauna and flora of the Chihuahuan Desert of the lowlands and the Rocky Mountains of the high elevations. The preservation of this area will depend upon sound management decisions. This volume is the result of a symposium held at The Museum …

Research In National Parks, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

This was our first involvement with research in the National Parks and we would like to make some observations concerning interactions among basic researchers, park personnel, and the philosophy on which our park systems are based. Our conclusions are not based only on our own experiences, but also on conversations with other basic researchers (especially those who contributed to this symposium) and with park personnel who have aided and worked with other researchers who were not employed by the National Park Service.

Germ Plasm Evaluation Program Report No. 2, U.S. Meat Animal Research Center

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The cattle Germ Plasm Evaluation Program at the U.S. Meat Animal Research Center is designed to characterize different biological types, as represented by different breeds, for the full spectrum of economic traits relating to growth, feed efficiency, reproduction, maternal ability and carcass and meat traits. The basic objective of this program is to develop an understanding relating to optimizing such biological factors as cow size, milk level, etc., in different feed environments and production situations.

The program was started with the 1969 breeding season. The first cycle (Cycle I, Phase 2)* involved breeding Hereford and Angus cows (Phase 1) by …

Histochemistry Of The Tissue Capsule Surrounding Intradermal Mites, Hannemania Spp. (Acarina: Trombiculidae) In New Mexico Amphibians, Jill J. Grover, Donald W. Duszynski, Barbara C. Bogan

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The first occurrence of larval intradermal mites, Hannemania spp., from New Mexico amphibians was recently reported (Duszynski and Jones, 1973, Int. J. Parasit. 3: 531-538). These parasites are always encapsulated by host connective tissue in the dermis of their host and the capsules are grossly visible below the epidermis. Basic histochemical procedures were used to help characterize and give us a better understanding of the structure and formation of this tissue capsule.

Recent Research Advances On The European Corn Borer In North America 1,2,3, T. A. Brindley, A. N. Sparks, W.B. Showers, W. D. Guthrie

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

BIOLOGY AND ECOLOGY

Distribution

The recorded distribution of the European corn borer, Osttinia nubilalis, has not changed significantly since Brindley & Dicke's review in 1963 (15), except along the southernmost portion of its range. Annual articles presenting the status of the European corn borer (3) indicate that each year the borer spreads into a few previously uninfested counties within known infested states. Sparks & Young (116) made a survey and found 34 of 35 counties infested in southern Georgia and concluded that the borer probably was present in all areas of extensive com production in Georgia. Light-trap records from Tifton, …

A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin

Bulletin of the University of Nebraska State Museum (1924–2023)

A new species of Pliocene peccary, Prosthennops (Macrogens) graffhami; is described from the Kimball Formation, Ogallala Group, Frontier County, Nebraska. This new species is the latest in geologic age and most advanced in the genus.

The remains of fossil vertebrates are generally rare in the upper part of the Ogallala group, and some have maintained that Hemphillian faunas such as Coffee Ranch and Smith County, Kansas, represent the latest Ogallala faunas. Later faunas than are typically considered as Hemphillian, containing more advanced forms, occur in the Kimball Formation and deposits of equivalent age. Known faunas which may …

Bears (Ursidae) From The Late Cenozoic Of Nebraska, C. Bertrand Schultz, Larry D. Martin

Bulletin of the University of Nebraska State Museum (1924–2023)

A ramus and partial premaxilla establish the presence of a new subspecies of Indarctos in the upper Pliocene (Kimball Formation, Ogallala Group) of Frontier County, Nebraska. An extremely large species of Agriotherium is represented by fragmentary remains from the middle Pliocene (middle part of Ash Hollow Formation, Ogallala Group) of Sherman County, Nebraska.

This study is part of a series of papers dealing primarily with the fauna of the Kimball formation in Nebraska (Barbour 1927, 1929; Barbour and Schultz, 1941; Schultz and Stout, 1948, 1961; Kent 1963, 1967; Tanner, 1967; Short, 1969; Martin and Tate, 1970; Schultz, Schultz, and Martin, …

Scimitar-Toothed Cats, Machairodus And Nimravides, From The Pliocene Of Kansas And Nebraska, Larry D. Martin, C. Bertrand Schultz

Bulletin of the University of Nebraska State Museum (1924–2023)

"Machairodus catocopis Cope" is shown to be a pseudaelurin cat belonging to the genus Nimravides Kitts. Nimravides thinobates (Macdonald) is a possible synonym of N. catocopis (Cope). Nimravides is compared with the Eurasian Machairodus-like cat, Dinofelis. Machairodus (Heterofelis) coloradensis is reported from the Kimball Formation, upper Pliocene (Kimballian) of Cheyenne County, Nebraska, and from the upper part of the Ash Hollow Formation, Pliocene (Hemphillian) of Sherman County, Nebraska. The Kimballian form is described as a new subspecies, Machairodus coloradensis tanneri.

The genus Machairodus has long been associated with the Hemphillian of North America and the …

A Revision Of The Nearctic Species Of The Genus Phronia (Diptera: Mycetophilidae), Raymond Gagne

USDA Systematic Entomology Laboratory

Phronia contains 86 species of small, brown or black mycetophilids. Adults of these fungus gnats are most often caught flying above the forest floor, especially along damp ravines. The fungivorous larvae have been found grazing on slime molds growing on the surface of decaying logs. Most species occur in the Holarctic region, but 1 described and several undescribed species are known from the Ethiopian region. In North America, there are 49 species, 33 of which are known also from Europe.

Age Determination Of Female Redhead Ducks, Charles W. Dane, Douglas H. Johnson

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

Eighty-seven fall-collected wings from female redhead ducks (Aythya americana) were as- signed to the adult or juvenile group based on "tertial" and "tertial covert" shape and wear. To obtain spring age-related characters from these fall-collected groupings, we considered parameters of flight feathers retained until after the first breeding season. Parameters measured included: markings on and width of greater secondary coverts, and length, weight, and diameter of primary feathers. The best age categorization was obtained with discriminant analysis based on a combination of the most accurately measured parameters. This analysis, applied to 81 wings with complete measurements, resulted in …

Herpesvirus Disease Of Salmonids, Ken Wolf, Tokuo Sano, Takahisa Kimura

United States Fish and Wildlife Service: Publications

A newly recognized virus, lethal for fry and fingerlings, has been isolated from brood stock rainbow trout (Salmo gairdneri) at the Winthrop National Fish Hatchery, Washington. A similar if not identical virus has been found in natural epizootics occurring annually since 1970 among fry of landlocked sockeye salmon (Oncorhynchus nerka) on Honshu Island, Japan. More recently, this agent was isolated from moribund and dead adult O. nerka on Hokkaido Island; Japan, but it remains to be determined whether or not the virus causes death in adult salmonids. The purpose of this leaflet is to bring the …

Response Of Nuclear Emulsions To Ionizing Radiations, Robert Katz, F. E. Pinkerton

Robert Katz Publications

Heavy ion tracks in Ilford K-2 emulsion are simulated with a computer program that makes use of the delta-ray theory of track structure, and the special assumption that the response of the emulsion to gamma-rays is 8-or-more hit. The Ilford K-series of nuclear emulsions is produced from a parent stock called K.0 emulsion, sensitized to become K.1 to K.5, and desensitized to become K–1 to K–3. Our simulations demonstrate that the emulsions K.5 through K.0 to K-1 are 1-or-more hit detectors, while K-2 is an 8-or-more hit detector. We have no data for K-3 emulsion. It would appear that emulsions …
