Osteoarthrosis In A Coyote X Dog Hybrid From Nebraska, B. R. Mahan, P. S. Gipson

University of Nebraska State Museum: Mammalogy Papers

Osteoarthrosis is described in a wild, 14-year-old coyote (Canis latrans) x dog (C. familiaris) hybrid shot in southeastern Nebraska. There was ankylosis of five vertebrae, the head of the left femur was absent, and periarticular osteophytes occurred throughout the skeleton. The age is significant because wild coyotes seldom live beyond 6 years and coyote x dog hybrids are considered to be less fit for survival in the wild than coyotes.

Analysis Of The Flehmen Display In American Bison (Bison Bison), Brian R. Mahan, Michael P. Munger, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

A tota1 of 873 Flehmen (lip curl) displays by bison (Bison bison) was recorded and statistically analyzed in relation to individual factors such as age and sex, and external factors such as wind speed, wind direction, temperature, humidity, and Flehmen stimulus to determine if differences between subgroups of individuals existed and if Flehmen was environmentally affected. The mean lip curl display duration for all individuals was 8.4 seconds. Statistical tests of Flehmen duration means grouped by Flehmen stimuli showed a significant difference (p < 0.05). Lip curl duration means for males (8.3 sec.) and females (9.3 sec.), "maturity classes", all age-classes, cow age-classes, and bull age-classes were significantly different (p < 0.05). Because of a marked decrease of duration means for "prime" bulls, some relationship between Flehmen duration and sexual behavior of bulls was suggested. Windspeed, humidity, and temperature were determined …

Mycobacteriosis (Tuberculosis) Of Fishes, S. F. Snieszko

United States Fish and Wildlife Service: Publications

Mycobacteria are widely distributed in nature. They are abundant in the soil, on the surface of plants, on the skin of vertebrates, in human food (e.g., milk and butter), and in animal feeds. Most mycobacteria are saprophytic, but some species are highly pathogenic and cause diseases such as tuberculosis and leprosy in humans, and similar diseases in mammals, birds, reptiles, amphibians, and fishes.

Mycobacteria that cause diseases of fishes differ considerably from those that cause diseases in humans and other mammals. Therefore, to avoid association between tuberculosis in mammals and mycobacterial infections in fishes, it is better to call the …

Avian Mortality Caused By A September Wind And Hail Storm, Kenneth F. Higgins, Michael A. Johnson

United States Fish and Wildlife Service: Publications

In recent study of nonhunting mortality of wild waterfowl, Stout and Cornwell (1976) identified weather as one of the more significant causal agents. This paper describes an occurrence of spectacular avian mortality caused by a severe thunderstorm in North Dakota on 8 September 1977.

The storm was associated with a low pressure system in South Dakota. It developed about Noon CST north of Dickinson, traveled eastward and generally north of highway 1-94, and continued into Minnesota at about 5:00 p.m. CST. The system moved at about 60 mph (97 km/h) over a 300 mile (483 km) stretch of the state; …

1978 Nebraska Beef Cattle Report, Leo E. Lucas, H. W. Ottoson, T. E. Hartung

Nebraska Beef Cattle Reports

Retail value of wholesale meat cuts is influenced by quality and the proportion of lean, fat and bone. Wholesale cuts vary widely in value; for example, loins and ribs sell for more than rounds, rounds more than chucks, and chucks more than flanks, plates, or briskets. This value difference has prompted many attempts to find breeding and feeding systems that will increase the proportion of high-priced cuts.

Results shown here characterize the composition of carcass wholesale cuts from 14 breed combinations that were part of a cattle germ plasm evaluation program at the U.S. Meat Animal Research Center, Clay Center, …

George Herbert Mead And Social Reform: His Work And Writings, Mary Jo Deegan, John S. Burger

Department of Sociology: Faculty Publications

There are two popular myths concerning the eminent philosopher and social psychologist George Herbert Mead: that he published little during his lifetime and that Mind, Self, and Society is his most important sociological work. This misrepresentation of Mead's contributions is partially grounded in the neglect of his work and writings on social reform. The misrepresentation of the significance of the almost seventy articles Mead wrote during his lifetime distorts the meaning of his concepts and has profound implications for symbolic interactionists who claim Mead as one of their founding fathers.

Movement And Migration Patterns Of Red-Winged Blackbirds: A Continental Overview, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

From 1924 through 1974, about 11,000 recoveries accumulated from the banding of over 700,000 Red-winged Blackbirds(Agelaius phoeniceus) in North America. A few studies have examined some of these data for specific localities during certain times of the year; however, no attempt has been made to examine the total recovery data to compile a general picture of continental movement and migration patterns. Increasing attention is being given to blackbird (Icteridae) and Starling (Sturnus vulgaris) populations in North America because of their reported crop depredations, health hazards, and nuisance aspects, especially when congregating in large roosts (Meanley,1975;Graham, 1976). Solutions to these problems …

Testicular Steroid Secretion In Response To Gnrh-Mediated Lh And Fsh Release In Bulls, B. D. Schanbacher, S. E. Echternkamp

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

Assay of frequently collected blood samples in four mature Hereford bulls indicated the existence of a tonic mechanism for the secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH), i.e., their episodic release was not observed. Increased plasma concentrations of LH and FSH, however, were obtained in response to an intravenous injection of 500 µg of gonadotropin releasing hormone (GnRH). These gonadotropins showed similar secretory profiles after GnRH, but the relative magnitude of the LH response (30-fold) was considerably greater than that of the FSH response (sevenfold).

Concentrations of testosterone in jugular and spermatic vein blood were increased sevenfold …

Climatic Change And The Extinction Of Large Mammals During The Quaternary, C. Bertrand Schultz, John M. Hillerud

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There is an abundance of soils and paleosols as well as terraces and terrace fills and erosional forms of pediments to aid in working out a precise stratigraphic sequence for the Quaternary animals. The dating and correlation of Quaternary deposits are complex, and we must realize that there were numerous glacial advances and retreats. A continuing reexamination of the relationship of the mammalian faunas to the paleosols, terrace fills, volcanic ashes, and other geologic features must be done in order to provide a proper framework for the interpretation of the mammalian stratigraphic sequences.

The horses and camels, which had so …

The Classical European Glacial Stages: Correlation With Deep-Sea Sediments, George Kukla

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Four glacials and three interglacials, recognized by classical Alpine and North-European subdivisions of the Pleistocene, were correlated with continuous oxygen-isotope records from the oceans using loess sections and terraces as a link (Fig. 15). It was found that the Alpine "glacial" stages are represented by sediments formed during both glacial and interglacial climates, that the classical Alpine "interglacial" stages do not represent episodes of interglacial climate but probably intervals of accelerated crustal movements, and that the physical evidence on which the North-European classical subdivision is based is misinterpreted due to lengthy gaps in the record.

It is recommended to discontinue …

Excavation At The Hot Springs Mammoth Site: A Late Pleistocene Animal Trap, Larry D. Agenbroad

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Construction work on a housing development in southern Hot Springs, South Dakota, during July 1974 exposed teeth, tusks, skulls, and post-cranial elements of mammoth. These were located in a small deposit of sand within the Spearfish Formation, a red shale of Permian-Triassic age.

The deposit was originally a topographic depression. Prior to construction, it stood as a ridge, the sand and gravel armoring the adjacent shale. It is currently a sandy knob left by the construction work.

Initial excavation during 1974 and 1975 (Agenbroad and Jones, 1975) was salvage and exploratory in nature. The abundant faunal remains from such efforts …

The End Of The Pleistocene In North America, Larry D. Martin, A. M. Neuner

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The excavations at Natural Trap Cave have stimulated our interest in the changes that took place some 12,000 to 8,000 years ago that mark the end of the Pleistocene. Of these changes, the extinction that occurred at the end of the Pleistocene in North and South America is near enough in time, and the animals involved are well enough known, to stimulate interest in the causal mechanism. With the possible exception of the extinction of dinosaurs at the end of the Cretaceous, none other has been the subject of more varied and extensive speculation. One of the most attractive hypotheses …

Excavations At Natural Trap Cave, Larry D. Martin, B. Miles Gilbert

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Among the more important questions addressed by students of earth history are those that relate to climatic change. This is especially true of change that has taken place during the last two million years of the "Ice Age." It is not an accident that a great deal of effort has been directed towards the Late Pleistocene, and our knowledge of Late Pleistocene environmental parameters has increased markedly in the past few years. However, our knowledge of these changes is still incomplete, and we still have some uncertainty about the cause and nature of Late Pleistocene climatic change, its possible relationship …

The Middle Missouri Tradition In Retrospect, Warren W. Caldwell

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The "culture history" of the Missouri trench in North and South Dakota has been phrased in climatological parameters. The life cycle of the Middle Missouri Tradition in particular seems to correlate closely with the Neo-Atlantic eposide, yet the interpretation is speculatory because appropriate climatic data are not available.

Political And Social Implications Of Possible Climatic Changes, Robert D. Miewald

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

There is something rather ludicrous about a learned paper on the political and social implications of the end of the world. Obviously, since we do not have much reliable historical information about this sort of event, the author can only offer some speculations which, however well-informed, are of debatable quality. And the reader, insofar as he or she actually believes in impending disaster, will doubtless be disappointed by the absence of any specific recommendations about how to survive. Yet while this exercise may seem foolish, it is undertaken because of the conviction that it would be even more foolish for …

Department of Entomology: Faculty Publications

Assessment of soybean seed quality in relation to the damage caused by Piezodorus guildinii (Westwood, 1837) (Hemiptera, Pentatornidae) at various infestation levels and at diferent stages of soybean development (Glycine max (L.) Merrill). Stinkbug effect on soybean seed quality was studied. Field tests were carried out in Guaiba, Rio Grande do Sul, 1974/75. Soybean plants were artificially infested at various densities of Piezodorus guildinii (Westwood, 1837) per 0.5m of row and at different stages of soybean development by means of isolation cages. Stinkbug infestations restricted from full bloom up to the beginning of pod formation do not result in …

Relating Wolf Scat Content To Prey Consumed, Theodore J. Floyd, L. David Mech, Peter A. Jordan

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

In 9 trials, captive wolves (Canis lupus) were fed prey varying in size from snowshoe (Lepus americanus) to adult deer (Odocoileus virginianus), and the resulting scats were counted. collectible scats were distinguished from liquid, noncollectible stools. In collectible scats, the small prey occurred in greater proportion relative to the prey's weight, and in lesser proportion to the prey's numbers, than did the remains of larger prey. A regression equation with an excellent the data (r² = 0.97) was derived to estimate the weight of prey eaten per collectible scat for With this information …

Review Of The Pheasants Of The World, Paul A. Johnsgard

Papers in Ornithology

This book, one of Delacour's three major monographs on avian families (the others being the Anatidae and, with Dean Amadon, The Cracidae), was originally published in 1951 but went out of print in the late 196Os, when it quickly became a collector's item. At the request of the World Pheasant Association, an avicultural organization concerned with galliform conservation, Delacour undertook a revision of the book, and a new colored plate has been prepared by R. David Digby. That Delacour, now in his late 80's, should undertake such a project at all is a testimony to the amazing vigor and enthusiasm …

Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Analysis of the bat fauna of the Antillean Islands suggest that the most probable source of invasion of the islands by bats is by overwater dispersal. The bat fauna of ·the Greater Antilles is unique, a percentage of endemism on each island being over 50 percent except for the Virgin Islands which has 33 percent endemics.

The richest bat fauna in the Antilles is on Cuba (32 species) followed by Jamaica (23 species) then Hispaniola (17 species) and Puerto Rico (16 species). The number of species found on Cuba is probably the result of the island's proximity to Central and …

Food Of The Atlantic Croaker, Micropogonias Undulatus, From Mississippi Sound And The Gulf Of Mexico, Robin M. Overstreet, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The diet of the Atlantic croaker from Mississippi Sound has been examined for the first time. Over 83 taxa were encountered, or more than were reported from croaker in any other region. We also found 60 taxa, 36 of which overlapped with the above, in croaker from various offshore stations in the Gulf of Mexico. In Mississippi Sound the frequency of occurrcnce of items revealed primarily crustaceans followed by polychaetes, molluscs, fishes, and less common items, and, in the open Gulf, molluscs appeared slightly more often than in inshore croaker and than polychaetes in offshore fish. The diets were assessed …

Food Of The Red Drum, Sciaenops Ocellata, From Mississippi Sound, Robin M. Overstreet, Richard W. Heard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examined digestive tracts of the red drum in Mississippi Sound contained mostly decapod crustaceans. Crustaceans accounted for 34 of 59 encountered taxa, more than reported from any other region. Nevertheless, the general diet for 104 fish with food contents out of the 107 examined is similar to that reported for red drum in several other studies from other areas. In addition to crustaceans, fishes followed by polychaetes occurred as the most important items (in 99, 43, and 15% of the drum with food, respectively). Blue crabs occurred in even more drum than the frequently encountered penaeid shrimps. Other commercial species …

Suppressed Rejection Of Trichinella Spiralis In Immunized Rats Concurrently Infected With Eimeria Nieschulzi, Donald W. Duszynski, Deborah Russell, Shirley A. Roy, Gilbert A. Castro

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This study deals with the effect of Eimeria nieschulzi infection on the host immune response to Trichinella spiralis. Six male Sprague-Dawley rats were inoculated with 10⁴ and six with 10⁶; sporulated E. nieschulzi oocysts. On days 2, 8, and 16 post-inoculation (PI), two rats from each infected group, and their paired uninfected controls, were killed and mucosal scrapings from their small intestines were assayed for peroxidase activity. Peroxidase levels were higher than corresponding control values on days 2 and 16 PI and significantly lower than the controls on day 8 PI. These data led us to …

Review Of Helminths Of Fish-Eating Birds Of The Palaearctic Region. I. Nematoda, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The title is accurate but the subject is a little misleading. One would expect that the fish-eating birds will acquire nematodes from the fish they eat. On the contrary, with one exception, Eustrongylides tubifex, as far as is known none of these nematodes use fish as normal intermediate hosts. A few species use fish as paratenic hosts. The book consists of an Introduction (2 pages), General Account of Nematodes (4 pages), the Systematic Part (233 pages), List of Fish-Eating Birds and Their Nematodes (22 pages), References (29 pages) and Index (13 pages). There are keys to families, genera, and …
