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 …

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 …

An Argument For The Open Ocean Siting Of Coastal Thermal Electric Plants, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

A great deal of research is yet to be done before we will definitely know all the effects of thermal electric generating plants. It is evident, however, that the chlorination of the intake water is definitely lethal to a high percentage of planktonic and other organisms; that thermal shock is detrimental to some of the more sensitive forms; that the continued exposure to high temperatures after thermal shock is lethal to many forms, especially the zooplankton; that the screening and turbulence in such plants is lethal to larval fishes and several invertebrates, and that immense amounts of waters are put …

The Impact On The Navy Of Public Concern With Control Of Pollution Of The Seas By Oil, Robert Augustus Fisher

Marine Affairs Theses and Major Papers

It is difficult at best to evaluate the biological and chemical damages of oil pollution, but the physical effects are graphically evident in the blackened beaches and coastlines around the world and in the floating "tar-balls" found in mid-ocean. It is this dramatically visible effect that has stirred public concern. Thus, prevention of such damage is high on the list of priorities for both national and international concern. In the face of the ever increasing potential for pollution, President Nixon has pledged that federal agencies will take the lead in pollution abatement programs.

Publications (WR)

This study developed from observations made during an earlier study on Lake Mead which was reported in CHE-70, Water Quality Study of Lake Mead. Results from that study indicated that poor-quality water was flowing into the Las Vegas Bay reach of Boulder Basin, Lake Mead. Also reports of deteriorating water quality, resulting in taste and odors in domestic water supplies taken from Boulder Basin as well as a reduction in the attractiveness of Las Vegas Bay for recreational uses caused by aquatic plants and algae blooms, indicated a need for a concentrated study concerning the effects of flows from Las …

Thermal Requirements To Protect Aquatic Life, Clarence M. Tarzwell

United States Environmental Protection Agency: Publications

Water temperatures affect aquatic organisms in a number of ways, both directly and indirectly. Some of the latter effects are quite subtle. High temperatures can have direct lethal effects but sublethal levels operating over long periods can be just as harmful through delayed lethal effects and the production of nonlethal stresses which eventually result in changes in the population, reduced growth or reproduction, and the lowering of resistance to parasites, dis ease, and competitors. Temperature, in combination with certain other factors such as day length, influences re producing processes. High water temperatures may stimulate or retard migration, spawning, feeding, and …

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 …

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.

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.

The Role Of The Coyote In An Infection Of Man And Animals, I. K. M. Liu

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

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 …
