Swine Brucellosis: How You Can Eradicate It
Swine Brucellosis: How You Can Eradicate It
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Swine brucellosis is a bacterial disease that affects swine, other domestic animals, and humans. Severe exposure causes the disease in cattle, dogs, cats, and poultry. The disease can spread from one species of animal to another, and from animals to humans. However, it does not normally spread from one human to another, or from humans to animals. The disease costs the swine industry about $10 million a year. Losses due to human infection cannot be estimated. Although human brucellosis, or undulant fever, is difficult to diagnose-especially in mild cases-a total of 892 cases were documented in the United States in …

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
SUMMARY
Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.
Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.
Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Pensternon In Your Garden, Glenn Viehmeyer
Pensternon In Your Garden, Glenn Viehmeyer
Department of Agronomy and Horticulture: Faculty Publications
A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they become better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.
Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard
Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard
Papers in Ornithology
A comparative morphological, behavioral, and electrophoretic study was undertaken on six populations of North American mallards that are currently considered by the A.O.U. Check-list to comprise four species and two additional subspecies. These include Anas p. platyrhynchos, A. d. diaxi, A. d. novimexicana, A. f. fulvigula, A. f. maculosa, and A. rubripes. These forms are essentially allopatric in their breeding distributions, with the major exception of A. p. platyrhynchos and A. rubripes, which overlap throughout a several-hundred-mile zone in east-central United States.
Geographic ranges and population sizes are estimated, and evidence is presented to indicate that the …
Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch
Notes On The Collared Pika, Ochotona Collaris (Nelson), In Alaska, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Maps showing the geographic range of the collared pika, Ochotona collaris (Nelson), have been published recently by Hall (1951) and by Hall and Kelson (1959). According to these, this mammal occurs in the mountains between the Tanana and Yukon Rivers, and in the Alaska Range as far west as Mt. McKinley. A specimen from the summit of the Chugach Mountains (Baker, 1951) was not included on the aforementioned maps. Osgood (1904) referred to two specimens collected by C. L. McKay in the Chogmit Mountains, east of Lake Clark at the base of the Alaska Peninsula, and also mentioned a sight …
Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar
Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar
United States Fish and Wildlife Service: Publications
It is well known that migrating helminth larvae do a great amount of damage to the host. Often, however, the host is relatively large and the damage done by few larvae is not serious. When the host is very small the mechanical damage, at least, must be proportionately greater for each larva present. An unusual case of mortality of small brook trout (Salvelinus fontinalis) roughly 2 to 4 inches long was brought to our attention. Examination of the mortalities, as well as survivors, revealed relatively large diphyllobothrid larvae (fig. 1) in the chambers of the heart, liver, pericardial …

Notes On Sanguinicola Davisi (Trematoda: Sanguinicolidae) In The Gills Of Trout, H. S. Davis, Glenn L. Hoffman, E. W. Surber
United States Fish and Wildlife Service: Publications
In 1953 the late Dr. Davis recorded the presence of an unnamed trematode from the gill blood vessels of fingerling cutthroat trout (Salmo clarki) and fingerling steelhead trout (Salmo gairdneri) at the Alsea Hatchery and in yearling rainbow trout (Salmo gairdneri) at the Oakridge Hatchery, both of the Oregon State Game Commission. Subsequently, two blood flukes, Sanguinicola davisi and S. klamathensis, were described from trout by Wales (1958). The present species was determined to be S. davisi by one of us (GLH). This report supplements data reported by Davis (1953) and Wales (1958). …

Pair-Formation Mechanisms In Anas (Anatidae) And Related Genera, Paul A. Johnsgard
Paul Johnsgard Collection
Although the" courtship" behaviour of waterfowl has attracted widespread interest and has been the subject of several major papers (e.g. Heinroth 1911, Lorenz 1951-1953), the actual means by which pairs are formed in most species of waterfowl remains unknown. We may conclude by inference that the females of most species of ducks must actively "select" their mates, for the elaborate male displays and plumage patterns present in the group can only be reconciled in terms of sexual selection. In addition, any observer of waterfowl will soon realize that it is the males which actively " court" the females, and that …

A Quantitative Study Of Sexual Behavior Of Mallards And Black Ducks, Paul A. Johnsgard
A Quantitative Study Of Sexual Behavior Of Mallards And Black Ducks, Paul A. Johnsgard
Papers in Ornithology
In recent years an increased interest in the use of behavioral characteristics in evolutionary studies has developed, and this is particularly true in the case of waterfowl. The classical studies of Heinroth (1911), who was one of the first to apply knowledge of waterfowl behavior to systematics, have been elaborated on by Lorenz (1941; 1951-1953) in his important contribution toward the understanding of relationships in the Anatinae. These, and other, studies have stressed the qualitative behavioral differences occurring among different species as providing possible isolating mechanisms through their presumed function of conveying species-specific recognition signals. To the present, no extensive …

Ec60-923 Care And Cooking Of Game Meats, Ethel Diedrichsen
University of Nebraska-Lincoln Extension: Historical Materials
Game meats, like domestic meats, are best when properly dressed and cooked. Good eating depends upon the treatment the animal receives when killed. For high quality meat, the animal should be properly bled, dressed and cooked under sanitary conditions. Much good game is ruined because this procedure is not followed.
This Extension circular will inform you how to care for your wild game and contains recipes on how to prepare and cook it.

The program of stocking farm and ranch ponds with fish produced at the national fish hatcheries was evaluated in January 1960 by a survey of 1,000 ponds. This sample, which was randomly chosen, represents 1/40th of the number of ponds stocked in 1957 by the Bureau of Sport Fisheries and Wildlife with bass, bluegill, redear sunfish and catfishes. A questionnaire, approved by the Bureau of the Budget, was employed in 25 States in connection with personal interviews of pond owners or managers by fishery biologists and hatchery personnel.
Pond owners reported that their principal reasons for building the ponds were …

A brief look at the map of Nebraska will readily point out the obvious fact that the sandhills comprise a considerable portion of the land area of the state. To be more precise, an area encompassing around 20,000 square miles or about one quarter of the total state area. This is indeed a vast prairie region long noted for its fine cattle and native hay crops. It is a region of vegetative dune sandhills, sandy basins and valleys, exposed ground water, spring seep lakes and marshes. Since much is already known concerning the land portion of the sandhills it is …

Coordination Of Mosquito Control And Wildlife Management Some Effects Of Mosquito Larviciding And The New Pesticides On Fishes, Clarence M. Tarzwell
United States Public Health Resources
It is apparent to one who has been brought up on a farm and who has worked in the fields of mosquito control, fisheries management, and water pollution abatement, that there are some conflicts of interest and methods used in these fields. There are, however, many common interests and areas in which the aims and objectives coincide. All too often in the past. there has been a failure to explore and stress common interests and a tendency to emphasize conflicting interests. Our present age of specialization in, training and interest is in part responsible for this situation. In order to …
Hybridization In The Anatide And Its Taxonomic Implications, Paul A. Johnsgard
Hybridization In The Anatide And Its Taxonomic Implications, Paul A. Johnsgard
Papers in Ornithology
Without doubt, waterfowl of the family Anatidae have provided the greatest number and variety of bird hybrids originating from both natural and captive conditions. The recent compilation by Gray (1958) has listed approximately 400 interspecies hybrid combinations in this group, which are far more than have occurred in any other single bird family. Such a remarkable propensity for hybridization in this group provides a great many possibilities for studying the genetics of speciation and the genetics of plumage and behavior, and it also provides a valuable tool for judging species relationships. It may generally be said that the more closely …

Nebraska Beef Cattle Reports
As we start a new decade it is appropriate to ponder for a moment on where we have been and where we go from here.
The past ten years have seen significant changes in all phases of animal agriculture. Probably the most spectacular changes came in the area of nutrition. During the past ten years significant advances were made in our knowledge on mineral and vitamin nutrition. Additional facts on the old problem of the ratio of concentrates to roughage have been added. Ways of supplementing poor quality roughage to obtain optimum production were learned.
