Rodent Control Problems In Developing Countries, Robert Z. Brown

Vertebrate Pest Conference Proceedings: 4th (1970)

None of the so-called developing countries has an adequate rodent control program at present. In only a few of these countries is any rodent control research occurring despite the fact that rodent problems are actually quite serious in many regions and potentially so in others. Expertise, techniques and materials from the developed countries are of limited usefulness because of major differences in rodent species involved, standards for food handling and sanitation, and in the cultural contexts in which rodent control must occur. Trained personnel, both for control work and the basic research needed, are in very short supply. In addition, …

Bird Damage Problems In Latin America, John W. De Grazio, Jerome F. Besser

Vertebrate Pest Conference Proceedings: 4th (1970)

In 1968 and 1969, biologists of the Denver Wildlife Research Center made field surveys in six Latin American countries to obtain information on bird damage problems in agriculture under an agreement with the Agency for International Development. Species of icterids, fringillids, psittids, columbids, and anatids caused most of the damage. Grain sorghum, corn, and rice were damaged most heavily. Other crops such as soybeans, wheat, cacao, and mangoes were also damaged, but seldom seriously.

Reproduction Inhibitors For Bird Control, M. R. Woulfe

Vertebrate Pest Conference Proceedings: 4th (1970)

Reproduction inhibitors are intended to maintain or control a population at a desired level; toxicants aim at elimination of the population. Azocosterol hydrochloride (SC-12937; 20,25-diazocholestenol dihydrochloride) is a long acting inhibitor of ovulation in the pigeon (Columba liyia) by interfering with cholesterol synthesis and egg yolk formation. Corn impregnated with SC-12937 at the 0.1% level by weight and fed for 10 days has been found to inhibit or diminish reproduction for 5-6 months. Population turnover rate, mortality and longevity of the feral urban pigeon are also discussed.

House Finch (Linnet) Control In California, Thomas K. Palmer

Vertebrate Pest Conference Proceedings: 4th (1970)

The house finch or linnet, Carpodacus mexicanus frontalis (Say) is a protected migratory nongame bird indigenous to California and found abundantly in all but the northern and mountainous areas. These finches attack more than twenty different crops and damage is demonstrated by fruit pecks, seed removal, and disbudding. When house finches cause agricultural damage control measures must be carried out under the general supervision of a county agricultural commissioner. Control practices involve the use of toxic baits, trap-decoy stations, and bio-acoustical devices. Most importantly, these control methods have been demonstrated to be safe, selective, and successful when employed by persons …

A Permanent Type Poison Station For Porcupine Control, William A. Neitro

Vertebrate Pest Conference Proceedings: 4th (1970)

A method has been devised to protect the poison strychnine-salt blocks used in controlling porcupines, Erethizon dorsatum, from the weather, killing of non-target animals and vandalism. An aluminum poison bait station has been developed which is light weight, durable, camouflaged, and safe. These structures are easily constructed and are relatively inexpensive when longevity is considered. Porcupines are controlled effectively and economically using this method

Conference Participants -- 4th Vertebrate Pest Conference,

Vertebrate Pest Conference Proceedings: 4th (1970)

The Fourth Vertebrate Pest Conference was the largest ever, with 275 registered participants and an estimated additional 50 to 75 persons who attended portions of the conference but did not register. The attendance was made up of individuals having varying interests in vertebrate pest problems, including foresters, agriculturalists, conservationists, pest control operators, vector control specialists, health officials, wildlife specialists, product distributors and manufacturers, instructors and researchers from twenty nine states plus the District of Columbia. Participants from Canada, England, Germany and Japan provided an international touch which contributed greatly to the success of the conference.

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.

Closing Remarks - Fourth Vertebrate Pest Conference, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 4th (1970)

On behalf of the California Vertebrate Pest Committee, which sponsors these conferences, I wish to thank all of the speakers for their contribution to the program and the session chairmen who kept the meeting moving so smoothly. We would like to extend a special thanks to the speakers and participants who have come from other countries to share with us some of their knowledge concerning vertebrate pest problems and their solutions. Hopefully, the acquaintances made here and the exchange of information with our colleagues from distant places will be the beginning of long-lasting friendships and will foster better communications between …

Surfactants As Blackbird Stressing Agents, Paul W. Lefebvre, John L. Seubert

Vertebrate Pest Conference Proceedings: 4th (1970)

Applications of wetting-agent solutions produce mortality in birds. The exact cause of death is undetermined, but it is believed that destruction of the insulating qualities of the plumage permits ambient cold temperatures and evaporation to lower the body temperature to a lethal level. The original concept of using these materials as bird-control tools was developed in 1958 at the Patuxent Wildlife Research Center, Bureau of Sport Fisheries and Wildlife, Laurel, Maryland. Early field trials by personnel of the Division of Wildlife Services and the Denver Wildlife Research Center indicated that ground-application techniques had promise, but limitations of the equipment precluded …

Response Of Nuclear Emulsion To Electron Beams, Robert Katz, E. J. Kobetich

Robert Katz Publications

A recent theory of particle tracks assumes that the probability P for grain development in nuclear emulsion depends on the local dose E of ionization energy deposited by secondary electrons (delta rays) in the neighborhood of the particle track. The response is assumed to be one of exponential survival; that is, if E₀ is the dose for 37% survival, then P = 1 – exp (-E/E₀). By calculation of the dose E(t) deposited at depth t in the emulsion by normally incident, monoenergetic electron beams, and applying the assumed dose-effect relationship, …

Rbe, Let, And Z/ΒΑ, Robert Katz

Robert Katz Publications

A call has been issued by Turner and Hollister in this journal for nomination of a suitable combination of charge and velocity to replace LET. It is the purpose of this communication to point out that no single combination of these variables can fully characterize track effects, as these are affected by the ratio of the range r_m of the delta ray of maximum energy to the radius a₀ of the sensitive volume.

A Summary Of Intergeneric New World Quail Hybrids, And A New Intergeneric Hybrid Combination, Paul A. Johnsgard

Papers in Ornithology

The exceedingly close affinities of the quail genera Colinus, Callipepla, and Lophortyx have been recognized for some time and have recently been emphasized by additional morphological (Holman 1961; Hudson et al. 1966), biochemical (Sibley 1960), and pterylographic (Ohmart 1967) evidence. Indeed, Holman has suggested that these three taxa might best be regarded as subgenera. Phillips et al. (1964) pragmatically merged Lophortyx with Callipepla; and Delacour (1961-1962) synonymized not only Lophortyx, but also Oreortyx and Philortyx, with Callipepla, yet retained Colinus as a separate genus. Although Ohmart (1967) questioned the validity of generically separating Lophortyx and …

A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin

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

A new genus of Pliocene Saber-toothed felid, Barbourofelis, is proposed and two new species B. fricki and B. morrisi are described. These two forms and other described material represent an unusual lineage of felids with long sabers, shortened crania, and massive postorbital bars. The tribal name Barbourofelini is proposed for this lineage which is presently known in North America from deposits ranging in age from Clarendonian through Kimballian. The Barbourofelini apparently migrated from Eurasia to North America in the Late Miocene or Early Pliocene. Sansanosmilus of the French Vindobonian appears to represent the ancestral stock of these cats. The …

Chiropteran Systematics, J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Provides an overview of the field of chiropteran systematics in a way that will introduce the non-chiropterologist to the subject. By way of example, we have alluded to several aspects of taxonomic research at different levels in the hierarchy. Recourse to the publications cited at the appropriate places in the text will amplify our remarks and provide a solid background in the current work of the discipline.

Basically, taxonomic characters are where the taxonomist finds them; some, but not all, will prove useful also in elucidating relationships and evolutionary descent of taxa. Much remains to be done in these areas, …

Auger Electrons From Argon With Energies 150-210 Ev Produced By H+ And H2 Impacts, D. J. Volz, M. Eugene Rudd

M. Eugene Rudd Publications

Secondary electrons in the energy range 150-210 eV produced by 125-300-keV H⁺ and H₂⁺ impacts on argon gas are measured as a function of their energy and angle of emission. Discrete line spectra are due to Auger transitions from L₂ and L₃ vacancy states as well as satellite transitions from multivacancy states. The widths, energies, and branching ratios of the L₂ and L₃ vacancy states are presented. Widths of these states are appreciably greater than those obtained with electron impact excitation. This can be attributed to the recoil velocities of the target atom …

System Analysis And Nematode Phylogeny, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The purpose here is to suggest a method which will permit understanding of the phylogenetic relationships of contemporary representatives of the phylum Nematoda without fossils. It is not my intent to again offer a phylogeny for the Nematoda. To say that no real benefit or knowledge of phylogeny or evolution is possible without fossils is succumbing to apathy. One cannot deny or ignore that all systems, morphological, biological and chemical manifested in modern forms developed by evolutionary sequence. It is true that with a complete fossil record the rates of evolution and developmental pressures could be accurately evaluated. However, in …

Federal Aid To State Legislatures: Problems And Potential, Walter J. Oleszek

Nebraska Law Review

Many scholars and other observers have argued that state legislatures are ill-equipped to play a vital role in the federal system, and yet they must play such a role if pressing national problems are to be met. Government at all levels faces the difficulty of resolving such issues as air and water pollution, urban blight, traffic congestion, inadequate housing, unemployment and underemployment, racial unrest, educational and recreational deficiencies, and rising crime. National, state, and local governments are partners in the federal system. With this goal in mind, a novel idea in federal-state relations has been proposed. It concerns the use …

The Genealogy Of The Outsider's Role In Disclosure Of Equity Ownership In Corporate Acquisition, Melvin Robert Katskee

Nebraska Law Review

The primary issue to be analyzed in this article is the effect which Public Law 90-439, providing for full disclosure of equity ownership of securities under the Securities Act of 1934, will have on the disclosure duty of an outsider making a tender offer for control of a corporation. Resolution of this issue inevitably leads to the battle currently being fought among those learned in the area over the wisdom or lack thereof of placing any disclosure duty upon the outsider.

Constitutional Law: The Right Of Access To The Press, Douglas F. Duchek

Nebraska Law Review

The right to publish one's views on any particular issue is protected from state infringement by the First Amendment. A problem arises when an individual who lacks printing facilities attempts to publish editorial advertisements in privately owned newspapers. Since he owns no printing press, should he have the right to rent the paper's facilities and circulation to present his views? The editorial advertisement is the same as a commercial advertisement; however, the editorial advertisement usually concerns an issue or controversy of a political nature. These advertisements are common around elections, but then they are encouraged by newspapers. The kinds of …

Hatching Of Sod Webworm Eggs In Relation To Low Temperatures, E. A. Heinrichs, Ellis L. Matheny

Department of Entomology: Faculty Publications

Eggs of Chrysoteuchia topiaria (Zeller), Crambus pascuellus floridus (Zeller), and Pediasia trisecta (Walker) were exposed to temperatures of 25, 15, 10, 4, and –10°C. Only those of P. trisecta hatched after exposure to 4°C for 30 days, while none hatched after exposure to –10°C. Eggs of none of the species hatched after exposure to 4 and 10°C for 60 days. Pre-exposure and post-exposure conditioning had no significant effect on percent hatch of P. trisecta eggs, while length of exposure period had a significant effect.

Parasitic Organisms In The Blood Of Arvicoline Rodents In Alaska, Francis H. Fay, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A Grahamella-like organism (Schizomycetes: Bartonellaceae) was found in erythrocytes of laboratory-reared northern voles, Microtus oeconomus Pallas, which had been inoculated intraperitoneally with a saline suspension of ground fleas, Megabothris abantis (Roths.), from wild northern voles captured at Lower Ugashik Lake, Alaska Peninsula. A live-trapped northern vole from the same locality harbored trypanosomes referable to T. microti (Mastigasida: Trypanosomatidae). Two morphologically similar but biologically different strains of piroplasms (Piroplasmasida: Theileriidae) of uncertain generic status were isolated from northern voles of Ugashik Lake origin and from northern red-backed voles, Clethrionomys rutilus Pallas, from the vicinity of Anchorage, Alaska. In the natural …

Walter Leland Cronkite- Fbi File

United States Department of Justice: Publications

Walter Leland Cronkite Walter Leland Cronkite (1916-2009), famous newscaster and journalist, worked for CBS News for five decades. Although the FBI did not investigate Cronkite, his name does appear in its files, usually in passing reference to his contact with an individual under FBI investigation or due to his professional contacts with the Bureau. These excerpts range from 1956 to 2000.

Particle Tracks In Emulsion, Robert Katz, E. J. Kobetich

Robert Katz Publications

A new theory of track formation in emulsion accounts for the tracks of charged particles on the basis of a theory developed earlier for the response of biological molecules and NaI(T1) to energetic heavy ions. The probability that an emulsion grain will remain undeveloped when exposed to δ rays depositing a mean energy E is assumed to be e^-E/E₀ where E₀ is the dose at which l/e (37%) of the emulsion grains remain undeveloped, as in the one-or-more-hit cumulative Poisson distribution. The parameter E₀ incorporates variations in emulsion properties and processing conditions. Calculation of …

Standing Waves On The Moon, Lewis T. Chadderton, Frans G. Krajenbrink, Robert Katz, Arcadio Poveda

Robert Katz Publications

The existence of local annular and radial structures in the environment of lunar craters, and of a global selenographic tectonic pattern, is ascribed in part to standing “moonquakes” established after impact or eruption.
