Evaluation Of Molting Areas Of Great Basin Canada Geese, Paul D. Arneson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Environmental factors at Neponset and Woodruff Narrows reservoirs were evaluated to determine their effects on molting Canada geese. More geese utilized Woodruff Narrows. Geese apparently favored the larger expanse of open water and adequate food supply.
Most of the molting geese were from the Bear River drainage. Some geese came from scattered areas in Utah, Idaho, Wyoming, and Montana. After molting, the geese flew to migration staging areas in southeastern Idaho before migrating to wintering areas in southern California and Arizona.
Females outnumbered males by 6 percent. The mean annual mortality rate for adult geese was 42 percent. Recovery rates …

The Ontogeny Of Social Behavior Of Uinta Ground Squirrels, D. Andrew Saunders
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The social behavior of juvenile Uinta ground squirrels (Spermophilus armatus) was studied for 2 1/2 years in northeastern Utah. The purpose of the study was to describe the developing social behavior of unconfined, marked squirrels. Their behavior was recorded with motion pictures and written descriptions from the time they emerged from the natal burrow until they entered hibernation.
Three phases of behavioral development were apparent. The first phase began when the juveniles appeared above ground and ended 5 weeks later. This was a period of socialization and consisted of behavioral patterns best described as play. The second phase …

The objective of this study was to clarify the relationships between drift rates, population density, production rates, key environmental factors, and movements of adults within two populations of stream insects (a caddisfly--Oligophlebodes sigma and a mayfly--Baetis bicaudatus).
Samples of benthic invertebrates (424 total) were collected every 28 days at four stations on Temple Fork of the Logan River, Utah, from October, 1967 to September, 1969. Samples of drift invertebrates (181 total) were collected every 14 days at three stations on Temple Fork during the same period. During summer months (June-September) a day and a night drift sample …

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 …
Outlook For Rodenticides And Avicides Registration, James O. Lee
Outlook For Rodenticides And Avicides Registration, James O. Lee
Vertebrate Pest Conference Proceedings: 4th (1970)
The history of pesticide regulations is presented. Major emphasis is on federal regulations. The evaluation of avicides and rodenticides is discussed and related to regu¬lations. Currently registered avicides and rodenticides are described along with a listing of efficacy criteria requirements. The future of registration of avicides and rodenticides is projected.
The Pharmacology Of Rodenticides, S. A. Peoples
The Pharmacology Of Rodenticides, S. A. Peoples
Vertebrate Pest Conference Proceedings: 4th (1970)
The compounds used as rodenticides are tremendously varied in their chemical structure and mechanism of action. With a few exceptions, these agents are generally poisonous to all animals, including man, and a great deal of study has been directed to their toxicity in animals other than rodents. However, the development of new compounds as Norbormide and certain antifertility drugs which are highly selective in their action may justify the hope that the ideal rodenticide free of secondary toxic hazards will soon be available. Until this happy announcement is made, a review of the pharmacology of the older compounds is in …
Notes On The Ecology Of Sewer Rats In St. Louis, Kyle R. Barbehenn
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 …

The Role Of The Coyote In An Infection Of Man And Animals, I. K. M. Liu
Vertebrate Pest Conference Proceedings: 4th (1970)
As part of epidemiological studies on hydatid disease in the central valley of California, a survey was made of seven counties of possible infections with Echinococcus granulosus in the coyote (Canis latrans). Of 173 animals examined, seven 4.O per cent) were found infected, six of them from Tehama County.
Current Status Of Plague And Plague Control In The United States, Jack D. Poland, Allan M. Barnes
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, …

The Rat In Hawaiian Sugarcane, Glenn A. Hood, Roger D. Nass, Gerald D. Lindsey
Vertebrate Pest Conference Proceedings: 4th (1970)
Heavy losses In Hawaiian sugarcane are caused by Polynesian rats (Rattus exulans), Norway rats (R. norveglcus), and black rats (R. rattus). Relative population levels, movement patterns, damage to sugarcane, and suggested timing of control during five stages of the 2-year crop cycle are described. The progress toward the registering of zinc phosphide for use in crops and the development of other rodenticides are mentioned.
Rodent Control In The Hawaiian Sugar Industry, Allen H. Teshima
Rodent Control In The Hawaiian Sugar Industry, Allen H. Teshima
Vertebrate Pest Conference Proceedings: 4th (1970)
Past and present concepts of rodent control at the 24 sugar plantations of Hawaii are reviewed with particular attention being given to the research efforts of the Experiment Station of the Hawaiian Sugar Planters' Association in improving operational rodent control in sugarcane. Hawaii offers a unique set of conditions: a 2-year crop cycle, a production of over 100 tons of sugarcane per acre, countless numbers of gulches and wasteland bordering crop fields, and a year-long growing season, all having an effect on rat population and habitat.
Vampire Bat Control: A Review And Proposed Research Programme For Latin America, Arthur M. Greenhall
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 …
New Factors Controlling Populations Of Land Vertebrates In Great Britain, N. W. Moore
New Factors Controlling Populations Of Land Vertebrates In Great Britain, N. W. Moore
Vertebrate Pest Conference Proceedings: 4th (1970)
The vertebrate fauna of Britain is impoverished by nature. Further, virtually the whole land surface has been altered radically by Man, and all vertebrate species have been profoundly affected both unconsciously and consciously by Man. The rate of change during the last quarter of a century has been far greater than at any other time; new deleterious factors - increased habitat destruction, increased human pressure and motor traffic, myxomatosis and a vast increase in pesticide use have coincided in this period. The public's attitude to several common species (e.g., rabbit, woodpigeon, fox and birds of prey) has been equivocal and …
Importance Of Wildlife Rabies Control, Richard L. Parker
Importance Of Wildlife Rabies Control, Richard L. Parker
Vertebrate Pest Conference Proceedings: 4th (1970)
ABSTRACT: Rabies in animals has been known in North America for over two centuries, and whether the disease was initially present in wild species or was introduced by dogs, it has been known in skunks for almost a century and a half. Today more rabies cases in wild animals are reported than in domestic animals, and a considerable proportion of both human and domestic animal exposures to the disease are the result of wild-animal contact. The most useful techniques for controlling wild animal rabies today are methods that reduce contact between infected individuals and susceptible individuals; these involve the manipulation …
Chemosterilants As An Approach To Rodent Control, Rex E. Marsh, Walter E. Howard
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
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 …
Mole Control, Lee W. Kuhn
Mole Control, Lee W. Kuhn
Vertebrate Pest Conference Proceedings: 4th (1970)
ABSTRACT: Four kinds of moles are found in the Pacific coast states but only the Townsend mole (Scapanus townsendii) in Washington and Oregon and the broad-handed mole (Scapanus latimanus) in California are considered economically important. Damage in agricultural areas is caused by mole mounds and burrow systems which reduce pasture production, make harvesting difficult by breaking or plugging machinery, contaminate hay and silage thus, retarding proper curing, contribute to soil erosion and make ready-made homes for invading meadow mice, pocket gophers, and other rodent pests. Moles also damage lawns, gardens, flower beds and occasionally eat or destroy valuable seeds and …
Destruction Of Conifer Seed And Methods Of Protection, M. A. Radwan
Destruction Of Conifer Seed And Methods Of Protection, M. A. Radwan
Vertebrate Pest Conference Proceedings: 4th (1970)
ABSTRACT: Agents responsible for tosses of conifer seed and methods for seed protection are reviewed. Published information indicates that much seed is destroyed, especially by seed-eating rodents and birds. Improvement of existing protective methods and development of new chemical means are necessary to overcome the problem.
Studies In Microencapsulation Of Rodenticides, P. B. Cornwell
Studies In Microencapsulation Of Rodenticides, P. B. Cornwell
Vertebrate Pest Conference Proceedings: 4th (1970)
Warfarin, zinc phosphide, norbormide and alphachloralose have been microencapsulated by the technique of coacervation and fed to laboratory rats (R. norvegicus) and mice (M. musculus). Results are given of experiments in which the concentration of rodenticide, wall material and phase ratio have been varied separately and in combination. Experiments are also reported in which normal and encapsulated rodenticide has been fed together in the same test diet.
