The Efficacy Of Several Broadcast Rodenticides In The Mid-Hudson Valley, New York, Ralph Pagano, Jay Mcaninch

Eastern Pine and Meadow Vole Symposia

As summarized by LaVoie and Tietjen (1978), many aspects of vole control using rodenticides including the costs/benefits of rodenticide use, applicator limitations in commercial orchards, and vole biology have not received proper attention. Data relating vole population levels to damage severity have not been generated and thus the exact benefits of control measures are difficult to analyze. Several aspects of vole biology have only recently been considered in rodenticide application procedures. Problems such as bait acceptance and percentage population control have created disparity in several rodenticide experiments (Richmond et al., 1978). A knowledge of vole use of vegetative cover and …

The Influence Of Soil Moisture, Texture, And Temperature On Nest-Site Selection And Burrowing Activity By The Pine Vole, Microtus Plnetorum, Donald H. Rhodes, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Pine voles (Microtus pinetorum) have long been recognized as a pest species in fruit orchards of the eastern United States (Hamilton 1935). These semifossorial rodents construct tunnel systems beneath apple trees where they eat entire roots or strip roots of bark and cambium. Hamilton (1938) reported numbers of pine voles within apple orchards as high as 200-300 voles per acre which is in sharp contrast to the relative scarcity of pine voles outside orchard situations (Crain and Packard 1966; Goertz 1971), These findings suggest that orchard habitat provides excellent conditions for pine vole growth and reproduction, although the specific components …

Effects Of Three Pine Vole Populations On Apple Tree Growth And Productivity, Milo Richmond, Pamela Miller, Chester Forshey

Eastern Pine and Meadow Vole Symposia

Few attempts have been made to quantify the damage to agricultural crops resulting from known densities of a particular pest. Availability of such information, even in its most basic form, is essential to making cost-effective management decisions. The question seems straightforward and simple; however, it is neither. For example, the damage caused by rodents in an apple orchard is not easily observed or measured. Moreover, the ultimate economic effects are dependant to s.ome degree upon tree age, variety and replacement cost; weather, productivity market prices, and a host of other manageable and unmanageable factors facing the grower. In addition to …

Social Influences On Reproduction In Pine Voles, Margaret H. Schadler

Eastern Pine and Meadow Vole Symposia

The presence of large populations of pine voles in apple orchards suggests that in the field reproduction of these pests has few constraints. Yet, evidence collected from our colony at Union College indicates that in the laboratory reproduction is not at random but instead is socially restrained and predictable. Unless these findings are artifacts of laboratory life, they may help explain some of the data collected in the field. Horsfall (1963) trapped voles every month of the year from an orchard near Cloverdale, VA. Since he found pregnant females in all collections, he concluded that reproduction occurred throughout the year …

Efficacy Of Spring Broadcast Rodenticides In The Hudson Valley, New York, Paul F. Steblein, Pamela N. Miller, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Subsequent to the prohibition of endrin use in New York State, a variety of alternate rodenticides and methods of rodenticide application have been examined in an effort to develop effective control measures for the pine vole, Pitymys pinetorum. These studies indicate that the manner in which the rodenticides are applied substantially influences their effectiveness in controlling pine voles. Specifically, in our experience placing poisoned bait directly in the animal’s subsurface tunnel systems has proved to be the most effective means of vole control. However, this method of bait placement is both time consuming and expensive. An alternate more cost-effective method …

Highlights Of The Seventh Eastern Pine And Meadow Vole Symposium, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

The Seventh Eastern Pine and Meadow Vole Symposium was held at the Cliffside Inn, Box 786, Harpers Ferry, West Virginia, March 3-4, 1983 for the purpose of assessing the current status of research, extension, and industry programs relating to vole damage to fruit trees. The meeting was held to provide a problem solving atmosphere in which growers, governmental agencies such as EPA, USDA, USDI, the chemical industry, and university personnel could observe the current thrusts of research and extension programs and their impact on future control strategies.

The Effects Of Forest Harvest On Water Quality And Aquatic Life (Phase I), Edmond J. Bacon

Arkansas Water Resources Center Technical Reports

A long term study on the effects of clearcut forest harvest and regeneration was conducted in a representative watershed of the Ouachita National Forest. Fourteen water quality parameters were analyzed to characterize baseline water quality. Water quality was classified as excellent. A total of 350 quantitative benthic samples and 15 ultraviolet light trap samples yielded 173 species of macroinvertebrates. Mean densities of macroinvertebrates ranged from 4,800/m2 to 23,040/m2 and averaged 12,499/m2 in the upper Little Missouri River. Twenty-two quantitative collections of fishes were made at representative riffles and pools. The average biomass estimates for riffles and pools were 5.69 kg/ha …

Industries Assistance Commission Inquiry Into Drought Assistance, Department Of Agriculture And Food, Western Australia, Australia. Industries Assistance Commission, J. Ripley

All other publications

This submission outlines the extent of drought in Western Australia in 1982/83, examines the adequacy of drought assistance measures and, after canvassing alternative assistance measures, proposes a preferred package of drought assistance measures.

The issue of whether or not the non-farm sector in rural areas should receive drought assistance, and if so what type, is not addressed in this submission. Rather the framework of discussion is restricted to the farm sector.

Weed Management In Alfalfa, William W. Witt

Kentucky Alfalfa and Stored Forage Conference

Weeds compete with alfalfa for water, nutrients, light, and space. This competition can decrease yields, lower forage quality, increase disease and insect problems, create harvesting problems, and initiate or poison the animals which will consume the forage. Premature loss of alfalfa stands is usually the result of the interaction of the pest complex - diseases, insects, and weeds.

The American Lobster Fishery Management Plan: An Assessment Of Its Impact On The New Hampshire Lobster Industry, John C. Belcher

Marine Affairs Theses and Major Papers

Exclusive fishery management jurisdiction between three and twelve nautical miles from the coast was granted to the Federal government by Congress in 1966. No federal regulations governing fishery management were ever promulgated, however. In 1972 an attempt was made to establish management regulations. Regional councils were formed to discuss industrial, managerial and scientific problems associated with fisheries within the territorial sea. Their success was limited. Not until the Fishery Conservation and ManagementAct of 1976 (PubIc Law 94-265) was enacted did a sound management structure exist at the federal level for fisheries regulation. This Act (FCMA) established a fishery conservation zone …

Fisheries Report No 59 - Potential Fisheries Capability Of The Ord In The Short, Medium And Long Terms, Dr N. Morrissy

Fisheries Research Reports

This report examines the history, future and problems of various methods for development and exploitation of the fisheries resources of the Ord.

The primary resource is the array of native fish and crustacean species, with the possible introduction of other desirable or noxious species being a subject for consideration.

Water resources, supporting these species, are the remaining natural Ord River downstream from the Diversion Dam at Kununurra, the stillwaters of Lake Kununurra and Lake Argyle, and, for aquaculture, the controlled distribution of water supply over the flat land of the irrigation system (Fig. 1). Another recognized resource is the climatic …

Protection Of Animals And Animal Experimentation: A Survey Of Scientific Experts, Norbert Lagoni, Joachim Fiebelkorn, Hans-Joachim Wormuth

Experimentation Collection

This article summarizes information from a survey of biomedical scientists, specifically pharmacologists and toxicologists, on the use of laboratory animals and the potential for replacing their use with alternative methods for the development and evaluation of pharmaceutical substances. The majority of those surveyed felt that the alternatives could supplement or complement animal tests, but not replace the tests altogether. However, most favored the use of nonsentient material in safety tests.

The Potential Role Of Local Ethical Committees In The Moderation Of Experiments On Animals In Britain, D. P. Britt

Experimentation Collection

Scientists working with laboratory animals in Britain are made aware forcibly that a serious ethical dilemma surrounds the use of animals in experiments. Certain vociferous sections of the community press the issue on the attention of the general public and media sources tend to propagate views expressed by the most extreme parties, while neglecting coverage of mature, rational opinion. It is, perhaps no bad thing for the scientific community to be frequently reminded to take a responsible attitude to the use of animals but recent overt, even illegal, activity on the part of extremist animal protectionist groups has encouraged a …

Ground-Water Hydrology And Projected Effects Of Ground-Water Withdrawals In The Sevier Desert, Utah, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

The principal ground-water reservoir in the Sevier Desert is the unconsolidated basin fill. The fill has been divided generally into aquifers and confining beds, although there are no clearcut boundaries between these units--the primary aquifers are the shallow and deep artesian aquifers. Recharge to the ground-water reservoir is by infiltration of precipitation; seepage from streams, canals, reservoirs, and unconsumed irrigation water; and subsurface inflow from consolidated rocks in mountain areas and from adjoining areas. discharge is by wells, springs, seepage to the Sevier River, evapotranspiration, and subsurface outflow to adjoining areas.

Measuring Species Diversity On Revegetated Surface Mines: An Evaluation Of Techniques, United States Department Of Agriculture, Forest Service

Mines and Mineral Resources

This report reviews the three most commonly used techniques for measuring species diversity in plant communities: (1) diversity indices, (2) rank correlation tests, and (3) similarity indices. The author discusses the suitability of each technique for assessing species diversity on mined land and evaluates the most often used indices, test statistics, or coefficients of each technique. Applications of the Shannon-Weiner diversity index, Spearman's rank order correlation coefficient, Motyka and others' and Bray and Curtis' version of Sorensen's similarity index, and Spatz' version of Jaccard's index for assessing mined land species diversity are presented in the appendix.

Report No 58 - 1982 - Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of involved the biological principles in decisions concerning duck-shooting seasons in the south-west of western Australia.

Conditions for waterfowl during 1982 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

1982 was characterized by exceptionally high rainfall in January and well-below average from February to October.

1982 was the seventh consecutive year of below-average rainfall in all five Meteorological of the south-west. 1976 to 1982 has thus been the south-west's driest seven-year period for more than seventy years.

The record-breaking rains of January caused widespread flooding in the …

Ubersicht Der Ergebnisse Der Ungarischen Zoologischen Expeditionen In Der Mongolischen Volksrepublik 1963-1968, Zoltan Kaszab

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Die Fauna der Mongolischen Volksrepublik war bis zu den 60er Jahren unseres Jahrhunderts fast unbekannt geblieben. Eine Ausnahme ist die Wirbeltierfauna, welche vor allem von russischen Zoologen gründlich erforscht und deren Resultate publiziert wurden. Dagegen hatten wir von den Wirbellosen nur spärliche Angaben in der Literatur, welche teils auf der Sammeltätigkeit russischer Forscher beruhen. Von ungarischer Seite war nur eine Expedition an der Jahrhundertwende (1898) von dem Grafen Eugen ZICHY durchgeführt worden, und während der kurzen Durchreise (3. bis 15. September) in der Mongolei hat sein Begleiter E. CSIKI, damaliger Kustos der Zoologischen Abteilung des Ungarischen Nationalmuseums, ein abwechslungsreiches zoologisches …
