Beef Cattle Progress Report, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Shipping fever is a respiratory disease "complex" of cattle. The disease causes extensive economic losses from death, loss of physical condition, inefficient feed utilization and treatment expense. The annual loss from this disease in the United States has been estimated to be $25,000,000.

In many respects shipping fever is similar to respiratory diseases of humans. It may occur in any season of the year, but is most common in the fall and early winter. Although any age animal may be infected recently weaned calves and feeder cattle which have just been moved from the range to feedlot are most susceptible.

Behavioral Isolating Mechanisms In The Family Anatidae, Paul A. Johnsgard

Paul Johnsgard Collection

The ducks, geese, and swans present a host of species-recognition and isolating-mechanism problems that are equaled by few other groups of birds. As a family, the Anatidae have provided the greatest number of interspecific hybridization records of any avian family (see Gray, 1958, and Johnsgard, 1960a) both in captivity and under natural conditions. A surprising number of these hybrids have proved to be fertile, even when obtained between what appear to be well-marked genera. This remarkable capacity for hybridization indicates that isolating mechanisms must be operating effectively if species are to retain their integrity under natural conditions. Since genetic isolation …

On Science And Social Science, Robert Katz

Robert Katz Publications

There are many definitions of science, and these are commonly based on literary and social usage rather than on the technical problem of distinguishing different areas of scholarship. To evolve an adequate definition we shall attempt to extract common elements from physics, biology, chemistry, geology, and astronomy, from those fields which are commonly called sciences. Any acceptable definition of science must be equally applicable to all of these, to all the natural sciences. To speak in the usual metaphor, we shall attempt a "scientific" definition of science.

Comparative Morphology In Nemic Phylogeny, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 1945 Simpson wrote: "Phylogeny cannot be observed. It is necessarily an inference from observations that bear on it, sometimes rather distantly, and that can usually be interpreted in more than one way." Certainly this applies to a study of nemic phylogeny where our reasoning is based upon degree of resemblance and subject to confusion by convergence and reversal. Many feel that, because fossil records are lacking, it is of little purpose to indulge in speculation on nemic phylogeny. Nemic taxonomy, however, requires such speculation when it is based upon comparative morphology. Our attempts in taxonomy are really an effort …

Pollution-Caused Fish Kills In 1962

Other Publications in Wildlife Management

This publication is the third annual report of fish kills caused by pollution occurring in the United States. The reporting of pollution-caused fish kills was begun by the Public Health Service in the Spring of 1960 in an effort to secure additional information on the effects of pollution in the Nation's waters, to elicit the cooperation and assistance of conservation groups in the States to help determine causes of fish kills and assist in their abatement, and to place responsibility for fish kills where it belonged.

The Surgeon General asked all State conservation and fish and game agencies to assist …

Helminths Of The Shrew-Mole Neürotrichus Gibbsii (Baird) In Oregon, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Helminths of the shrew-mole from Oregon are described. They include a cestode Hymenolepis neurotrichi sp. n., a trematode Microphallus aspalacis sp. n., and the third-stage larva of an undetermined species of Porrocaecum (nematode), probably P. depressum (Zeder, 1800), or P. angusticolle (Molin, 1860). Preserved viscera of ten animals were examined. Three were infected.

Development Of Water Quality Criteria For Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

It is now recognized that water pollution is an important problem, that it becomes more widespread and serious as population and industry expand, and that something must be done if aquatic life resource are to be saved and their productivity maintained. In the past there has been a great deal of uncertainty in approaching this situation and a general lack of understanding of the details and ramification of the overall problem. In the efforts for the abatement of pollution, only a few clearcut objectives have been established. Knowledge is lacking as to what the objectives should be. There is still …

The U.S. Feed Concentrate-Livestock Economy's Demand Structure, 1949-1959 (With Projections For 1960-70), James B. Hassler

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Several years ago, members of the NCM-19 Technical Committee on grain marketing research decided to do more detailed research on the spatial aspects of the livestock-feed economy. The major objectives of this study are (1) to quantify the demand functions for the major animal products of agriculture at the retail level, (2) to derive the demand functions for the unprocessed forms at the farm level, (3) to derive the equilibrium demand functions for feed concentrates at the farm level, (4) to estimate the separate annual impact rates of trends in per capita income, marketing costs, conversion rates, and population on …

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis

University of Nebraska State Museum: Staff and Affiliates, Publications

The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

Northern Pike, Esox Lucius, In Alkaline Lakes Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Pike (Esox lucius) were studied in alkaline sandhill lakes from 1956 through 1961. Fry and fingerlings were released in alkaline environments as part of a continuing ecological study of survival and growth of northern pike in Nebraska waters. Survival and growth were determined by intensive nettings at release sites. Chemical, biological, and physical characteristics of each lake were investigated (Table 1).

The majority of the nearly 2,000 Nebraska sandhill lakes may be classified as alkaline eutrophic of the bicarbonate-sulfate group (McCarraher). Salts other than chlorides predominate in these natural lakes supporting a biota somewhat different from inland chloride …

Significant Developments In European Corn Borer Research1,2, T. A. Brindley, F.F. Dicke

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

Since its identification as an introduced pest in 1917, the European corn borer, Ostrinia nubilalis (Hilbner), has been investigated under widely different environmental conditions. During the first decade, the research was directed largely toward studies on biology and the development of control measures that were cultural, biological, and mechanical in nature. The important initial objective was a delaying action to reduce popula­tions in the infested areas, thereby impeding the spread to the central Corn Belt. Legislation was enacted making it compulsory for growers to practice stipulated population-reducing measures. The spread west and south and the economics of harvesting and cultural …

Development Of Systemic Insecticides For Pests Of Animals In The United States1, R.C. Bushland, R.D. Radeleff, R.O. Drummond

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

The first encouraging results in the search for systemic insecticides were obtained in 1944 by Lindquist and his co-workers (53), who found that bed bugs, Cimex lectularius Linnaeus and C. hemipterus (Fabricius), died after feeding on rabbits treated orally with DDT or pyrethrins. In 1946, Knipling and associates (48) treated rabbits with oral and intravenous dosages of insecticides,and reported that rabbits tolerated treatments of lindane and 2 -pivalyl-I,3-indandione at rates that were lethal to mosquitoes, Aedes aegypti (Linnaeus), and human body lice, Pediculus humanus humanus Linnaeus when feeding on the rabbits. These findings, made at the Orlando, Florida, laboratory of …

Toxic Hazards In Aerial Application, Paul W. Smith

United States Department of Commerce: Staff Publications

An analysis of the hazards accompanying the aerial application of toxic pest-control chemicals is presented. The nature of the chemicals, the symptoms of toxicity, recommended treatment, and suggestions for safe-handling, are discussed.

The introduction of the chlorinated, cyclic hydrocarbons for large-scale use as agricultural insecticides somewhat less than two decades ago, marked the beginning of a new era in agricultural pest control. In the intervening years, new chemicals, many of them engineered for specific agricultural purposes, have appeared in rapid succession. The large number and wide variety of these compounds, and their new and unfamiliar chemical and toxicological properties, have …

A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff

Commensal Rodents, W. W. Dykstra

Vertebrate Pest Conference Proceedings: 1st (1962)

The evolution of effective rodent control has been greater in the past 20 years than during the previous 200 years. Mankind need no longer fear the "black death," typhus, and other rodent-borne diseases. Likewise, there is no longer any reason why we must bear the cost of serious economic losses because of commensal rodent damage to property. Unfortunately, the latter still totals many millions of dollars each year. Damage and contamination of food products by house mice now probably equals or exceeds that caused by rats.

Ectoparasite Control In Public Health , Allan M. Barnes

Vertebrate Pest Conference Proceedings: 1st (1962)

The inclusion of a chapter on ectoparasite control in a work otherwise devoted to vertebrates has a great deal of justification; the ecologies of vertebrates and their invertebrate parasites are inseparable, thus, the vertebrate control specialist is brought into intimate contact with ectoparasites and ectoparasite problems. In many cases, the need for vertebrate and ectoparasite control problems is one, and knowledge of techniques in both areas is required. The term "ectoparasite" groups a broad array of invertebrate animals externally parasitic on larger animals, many of them blood feeders in at least one stage of their life cycles. The ecological relationships …

Federal Law And Vertebrate Pest Control, Justus C. Ward

Vertebrate Pest Conference Proceedings: 1st (1962)

Shortly after the passage of the Federal Insecticide Act of 1910, mammal control specialists in the Bureau of Biological Survey began to consider a similar law to cover the chemicals with which they were concerned. Work on the project went slowly and spasmodically, but reached the point of having a Federal Rodenticide Act available for study and possible revision in 1928. At this time, the mammal control chemicals in use were limited to strychnine--alkaloid and sulphate-arsenic, barium carbonate, thallium sulphate, phosphorus, sodium and calcium cyanide, carbon disulphide, and red squill. Strychnine alkaloid was about the only predatory animal control agent, …

Concluding Remarks Of Appreciation With Comments On Histoplasmosis And Cryptococcosis, Philip J. Spear
