Keynote Address --- "The Year Of Ecology", Robert I. Cushing

Vertebrate Pest Conference Proceedings: 4th (1970)

It seems to me that there are at least two things we should be concerned about. First, I believe there is a real possibility that the environmental quality bandwagon will get to playing so loud and to rolling so fast that there can be some unfavorable consequences in food production and processing-—the job I work at and that some of you work at. Second, I believe there are signs that we could lose our balance—-that we could be making decisions on emotional instead of rational grounds. Reason seems to be in danger from an epidemic of emotion. And we need …

Notes On The Ecology Of Sewer Rats In St. Louis, Kyle R. Barbehenn

Vertebrate Pest Conference Proceedings: 4th (1970)

The awareness, if not the magnitude, of problems caused by sewer rats has increased in the United States in recent years. Thus, current concern with the more general problem of urban rats is leading many city agencies to incorporate plans for controlling sewer rats in budgets that are already severely strained. The most effective programs for controlling pests are those based on an intimate knowledge of the interactions between the target species and its environment. Some basic studies of sewer rat ecology were begun in St. Louis, Missouri, in February, 1969. Since the initial results have provided information that should …

Current Status Of Plague And Plague Control In The United States, Jack D. Poland, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 4th (1970)

During the first quarter of the 20th century massive rat-borne plague epidemics occurred in port cities of the United States in conjunction with the last world-wide pandemic which originated in China in 1893. By 1950, plague was found to be firmly established in wild rodent populations in states west of the 100th meridian. Presumably because of improved sanitation coupled with retreat of the world-wide pandemic there have been no human cases in this country associated with urban rats since 1924. However, sporadic cases, fewer than 10 per year, are reported as due to contact with wild rodents, lagomorphs, rural rats, …

Vampire Bat Control: A Review And Proposed Research Programme For Latin America, Arthur M. Greenhall

Vertebrate Pest Conference Proceedings: 4th (1970)

In Latin America paralytic rabies transmitted by vampire bats is a major cause of death in cattle. This problem becomes more acute as countries attempt to increase livestock production to feed rapidly expanding human populations. Vaccination has been the principal weapon against rabies, however this offers no protection to domestic animals and poultry against daily predation of vampire bats. Established methods of vampire bat control, though limited, have proved effective and should be continued while more effective methods are being developed and tested. Existing methods are discussed in some detail. Of the approximately 200 kinds of bats found in Latin …

Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard

Vertebrate Pest Conference Proceedings: 4th (1970)

Capitalizing on research directed toward oral contraceptives for humans, a wide variety of compounds are now under study for their practical value in inhibiting rodent reproduction to suppress detrimental populations. This paper discusses the specifications of ideal rodent chemosterilants and the advantages of chemosterilants over other methods of control, and compares the potential values of chemosterilants acting on females, males, and both sexes. Specific situations are detailed where chemosterilants will be most valuable in rodent control, together with proposed methods of application. Chemosterilants are not expected to become a panacea for control, but since they are based on sound biological …

Olfaction In Rodent Control, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 4th (1970)

A brief survey is presented of current knowledge on olfaction in rodents and the various roles that odors may play in modifying rodent behavior. Some species at least utilize olfactory cues: to locate food items; to recognize their mother and mates; to mark territory; as an involuntary population density regulator; possibly to recognize predators; as a warning cue against a repellent or toxic substance (poison-bait shyness); and probably, for many other behavioral purposes. The value of using artificial odors in rodent baits to increase bait acceptance is not yet well documented. The addition of attractive natural odors may increase detection …

Current Work On Bird Hazards To Aircraft, Victor E. F. Solman

Vertebrate Pest Conference Proceedings: 4th (1970)

Collisions between birds and aircraft have caused loss of human life and millions of dollars worth of property damage. The advent of even larger planes may reduce airframe damage, but it seems doubtful that engine damage will be significantly reduced. Dealing with the problem biologically, involves combating the hazards caused both by birds on or near the ground at airfields, and by birds on mass migrations at altitudes up to several thousand feet above ground. Airports can be designed or altered to minimize their attraction to birds. The chance arrival of a flock of birds must be treated as an …

Existence Of Fixed Poles And Their Role In Conspiracy, Paul Finkler

Paul Finkler Papers

It is shown that unitarity allows fixed poles at certain nonsense points of either right or wrong signature. The conditions for the existence of these poles are found. These conditions are then used to locate the poles allowed in hadronic reactions. Possible mechanisms for the poles are considered. It is then argued that fixed poles provide the most natural explanation of the conspiracy phenomenon.

Concentration Of Co, In The Air Above A Sugar Beet Field, K.W. Brown, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

The concentration of CO, in air sampled above a sugar beet crop was measured during July, August, and early September 1966 at Scottsbluff, Nebr. During July the mean daytime concentration decreased from 310 ppm to 283 ppm as the leaf area index increased from 0.8 to 4.0. Only small deviations from the mean daytime Concentration of 283 ppm occurred during the remainder of the season. The mean nocturnal concentration during this period was 320 ppm and was more variable than the daytime concentration. The daily amplitude of concentration averaged 70 ppm and was as great at times as 100 ppm. …

The Effect Of Putrefaction Of Eggs Upon Residue Analysis Of Ddt And Metabolites, Bernard M. Mulhern, W. L. Reichel

United States Fish and Wildlife Service: Publications

In conjunction with environmental pollution studies, it often is necessary to analyze field-collected eggs that are partially decomposed. The effect of putrefaction upon residue analysis, however, is not known and the experiment reported here was designed to determine if recoveries of DDT, DDE, and DDD differed between fresh and addled eggs and also if putrefaction causes appreciable degradation of DDT.

American Bar Foundation Project Legal Services Survey Report, Douglas N. King, David R. Parker, Peter M. Smith, James R. Cook, Samuel F. Seever

Nebraska Law Review

During March of 1969, the Nebraska Law Review accepted a grant from the American Bar Foundation to fund a survey of legal services for the poor in civil matters in the State of Nebraska. This report is the culmination of that survey and was prepared with a threefold purpose: (1) to present the data generated by the survey, (2) to serve as a planning guide for the Nebraska State Bar Association, and (3) to document the procedures used in conducting the survey to assist subsequent studies of a similar nature. To fulfill these objectives, the report is organized as follows: …

American Sculpture, Norman A. Geske

Sheldon Museum of Art: Catalogs and Publications

The occasion for the present exhibition, the dedication of the Sheldon Sculpture Garden, marks the completion of one of the most important gifts ever made to the University of Nebraska and to the people of the state. The importance of the gift lies not only in the fact of the distinguished building and the art objects which it houses, but also in the fact of their presence as a potential, a place and a situation where the creative spirit, traditional and activist, may find a laboratory, a workshop and an audience.

The garden is first of all a physical enlargement …
