House Mouse Behavior And Its Significance To Control, W. D. Klimstra

Vertebrate Pest Conference Proceedings: 5th (1972)

It seems explicitly evident that animal control practices must now, and especially in the future, emphasize fuller appreciation of the habits of each kind of animal. Further, this will require consideration be given to behavioral aspects as expressed by a population as a whole of a given species, as well as each individual animal within that population. Animals react with one another and with all characteristics of their environment; and, this in turn results in an identifiable reaction or behavior of each population as a unit of social organization. Although within broad limits some aspects of these responses, whether individual …

The Influence Of Attractants And Repellents On The Feeding Behaviour Of Rattus Norvegicus, J. O. Bull

Vertebrate Pest Conference Proceedings: 5th (1972)

Poison baits are extensively used for commensal rodent control; considerable folk lore exists regarding the use of additives to induce rodents to come to and eat poison baits. This paper describes a rational evaluation of attractants and the influence of different odours in inducing Rattus norvegicus to feed at given locations. The influence of certain repellents was also examined. Tests consisted of attempts to induce rats to feed at non-preferred sites or to repel them from preferred sites. Place preference was the dominant factor in feeding by rats, and odours failed to influence feeding activity significantly.

An Innovation In Roof Rat Control, Donald R. Brothers

Vertebrate Pest Conference Proceedings: 5th (1972)

Within the past ten years, the roof rat (Rattus rattus) problem in residential Santa Clara County has developed from an insignificant nuisance to one of major concern. When a considerable number of complaints to the Santa Clara County Health Department reported roof rats on telephone cables, a study was made of 29 city blocks to determine the feasibility of utility pole baiting as a means of roof rat control. In the baiting process, rat signs were commonly observed on telephone equipment attached to the utility poles. A correlation was observed between bait consumption and the close proximity of vegetation to …

Rat Reduction With Indigenous Methods, P. J. Deoras

Vertebrate Pest Conference Proceedings: 5th (1972)

Mujumdar (1968) has recorded that there are 566,000 villages in India as compared to 2699 towns, and that there is 322,460,000 acres of cultivable land and probably 500 million domestic rats in India. The food production target in 1968 in India was to be 110 million tons. National rodent committee 1967 mentioned of a loss of one million ton of food grains by rats alone. Deoras (1968) has mentioned that 3 common rats in Bombay were consuming 26 gm. of food grains per day, that is, about one ounce, while the quantum of cereal rations available per man in some …

KWRRI Research Reports

The institutions responsible for water resources management in the United States have originated as political responses to major social issues. Each agency institutionalized a procedure for structuring and comparing alternatives in the formulation of its total program. Each agency originally sought to promote effective resolution of its social issue (flood control, development of arid lands, soil erosion, etc.), but more recent efforts have sought better coordination among agency practices through a common procedure largely derived from economic theory. Any procedure, however, varies in application with the interpretation and judgment of individual planners. Today, public pressures have brought political directives requiring …

Carbon And Nitrogen As Regulators Of Algal Growth In Treated Sewage, Edward G. Foree, Charles Reece Scroggin

KWRRI Research Reports

Continuous flow algal cultures were grown under three different growth conditions using secondary sewage treatment plant effluent as the growth medium. The only variable within each run was the hydraulic residence time. The concentrations of growth regulating nutrients were varied between the runs so comparisons of the algal mass, composition, nutrient uptake, and genera could be made. The importance of CO₂ availability for algal growth was also studied. A kinetic theory which based algal growth on cellular nutrient concentration was verified. The second phase of the study was a batch culture study in which the same growth medium was …

Opening Remarks - Fifth Vertebrate Pest Conference, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 5th (1972)

It is a pleasure to welcome you to the Fifth Vertebrate Pest Conference. It has been 10 years since the first Conference was held in Sacramento in February of 1962. The attendance has grown at each successive conference and, from the looks of the audience this morning, we shall surpass all previous records. It would, however, be wrong to judge the significance of this conference on attendance alone, for we are equally or more concerned with the quality of the conference and its ultimate contribution to the specialized area of wildlife management. The Conference is sponsored by the California Vertebrate …

Keynote Address - Vertebrates: A Resource Needing Management, Donald A. Spencer

Vertebrate Pest Conference Proceedings: 5th (1972)

A veritable storm of concern for wildlife - approaching biotechnology - is currently sweeping the nation. Some of this concern has a sound basis. But the very best of ideas and programs can be carried so far that they become irrational. We appear to be driving head-on into irrational actions with respect to environmental good housekeeping. The vegetative cover in the United States has changed markedly as the result of Man's occupancy, reducing the habitat on which some wildlife species depend and greatly enhancing that of others. Competition, a no-holds-barred struggle, continues unabated between all living things for the finite …

The Extending Of Cotton Rat Range In California - Their Life History And Control, Dell O. Clark

Vertebrate Pest Conference Proceedings: 5th (1972)

Cotton Rats (Sigmodon hispidus eremicus Mearns) are known to have reached the Imperial Valley in 1921 from the Colorado River along canal banks. Recently (1967-69) cotton rats were found distributed throughout the irrigated portion of the Imperial Valley, Imperial County, California. Limited crop damage has occurred and is described. Life history information is included. Control measures are listed.

Related Laws On Exotic And Native Wild Animals, Donald F. Stork

Vertebrate Pest Conference Proceedings: 5th (1972)

This paper is submitted in an effort to acquaint the personnel of allied State agencies with related laws which control the public and private possession of live exotic and native wild animals. The need for this common knowledge of related laws by agencies with law enforcement responsibility is readily apparent when the annual number and related problems from imported or resident wild animals in California are examined. In addition to resident wild animal populations, millions of fish and thousands of mammals, birds, and reptiles enter California each year through the utilization of most methods of transportation. Most of these imported …

Eutrophication Factors In North Central Florida Lakes, H. D. Putnam, Patrick L. Brezonik, Earl E. Shannon

United States Environmental Protection Agency: Publications

A small Florida lake has been receiving a regimen of nutrient addition equivalent to 500 mg/m³-yr N and 43 mg/m³-yr P since 1967. Data has been accumulated through 1969. The effect on the lacustrine ecosystem of various biogenes includes production by primary producers, species diversity of plankton and certain production estimates at the secondary trophic level using natural populations of planktivorous fish. Plankton production using isotopic carbon is ca. 58 grms/m²-yr; Species diversity is slowly changing to a mixed chlorophycean and yellow-green. Biomass of benthic green filamentous types has increased slightly. Nutrient addition has …

Pollution From Sewage Loading In River And Lakes Downstream From Bemidji, James Ludwig

Journal of the Minnesota Academy of Science

The deleterious effects and downstream distribution of pollutants from domestic sewage discharged at Bemidji, Minnesota, are examined with reference lo parameters for pollution as defined by the state's Pollution Control Agency (PCA). Periodic overloading of the resort city's sewage treatment plant also is considered, along with problems pertinent to a community upstream of popular vacation facilities on a lake and river system.

Nickel Mining And The Bwca: A Question Of Priorities, Walter E. Parham

Journal of the Minnesota Academy of Science

A conflict in potential land use of the Boundary Waters Canoe Area (BWCA) exists between those who wish to see the area open to mining and those who want it retained as a natural wilderness. A review of information available to the public which relates to possible nickel mining within the BWCA suggests that the BWCA itself in its natural state is a more valuable resource to the people of the United States than it is as a source for nickel. The high U.S. rate of consumption of nickel, our use of nickel in products in which it is non-essential, …

A Survey Of The Fishes Of The Mulberry River, Arkansas, Larry L. Olmsted, Gary D. Hickman, Donald G. Cloutman

Arkansas Water Resources Center Technical Reports

Announcement of plans to dam Mulberry River, Arkansas, by the United States Army Corps of Engineers has generated some dispute. Most agruments against damming the stream revolve around environmental degradation and loss of aesthetic values. This report serves as a pre-impoundment survey of the fishes of the Mulberry River so that possible effects of impoundment can be more objectively assessed. Knowledge on the fishes of the Mulberry River is severely lacking. The first study was by Jordan and Gilbert (1886) who collected in the southern U.S. in July, August, and September, 1884. They collected in many streams in Arkansas including …

Obstacles To Economic Progress In Ethiopia's Red Sea Coast And Gulf Of Aden, Abraham Alemayehu

Marine Affairs Theses and Major Papers

Ethiopia is a coastal state whose overall economic progress has been and still is being affected by a number of coastal and related obstacles. This paper will attempt to discuss each and every one of these obstacles and other relevant aspects in order to justify as much as possible Ethiopia's lack of progress in economic development. By no means these are not the only obstacles responsible for affecting the country's entire economic progress. The obstacles that I would like to present here are only those which are more or less directly related to maritime, geographical and geopolitical problems on the …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince

Fisheries Research Reports

The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.

Ir. recent times, three parties have visited the Archipelago and examined …
