Movements Of Meadow Voles In Winter: Implications For Vole Management In Orchard Habitat, Dale M. Madison, Randall W. Fitzgerald, William J. Mcshea

Eastern Pine and Meadow Vole Symposia

The movements of meadow voles in a field population were studied using radiotelemetry during fall and winter. The voles changed from a dispersed, solitary dispersion pattern during early autumn to social clusters with communal nesting during winter. This shift occurred as the daily median temperature approached freezing. Movement was inhibited and localized during winter, except under snow when the voles exhibited a freedom of movement not experienced during other times of the year. Overwinter management of meadow voles in orchard habitats is discussed in view of these findings.

Movements And Habitat Use By Pine And Meadow Voles In An Orchard, Ralph E. Pagano

Eastern Pine and Meadow Vole Symposia

Several radiotelemetry studies have now been completed in the orchards of the mid-Hudson Valley, New York. The results of one of these projects, a l2-month study of the movements and habitat use of pine and meadow voles, will be reported on here. The success of an integrated vole management program using cultural practices and rodenticides depends a great deal on knowing the movements and habitat use of the two orchard vole species. Species interactions that could lead to differential use of the orchard habitat are another important element in a vole management program. This study focused on three major objectives: …

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 …

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 …

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 …

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 …

Abundance And Biomass Of The Meiobenthos In Nearshore Lake Michigan With Comparisons To The Macrobenthos, Thomas F. Nalepa, Michael A. Quigley

United States Department of Commerce: Staff Publications

The meiobenthos of nearshore southeastern Lake Michigan was quantified by taking cores from three depths (11, 17, and 23 m) at monthly intervals from May to November 1976-79. Total meiobenthic abundance rangedfrom 69,700/m² to 1,300,000/m² and total biomass rangedfrom 0.03 to 0.87 g/m². Nematodes accounted for 80% of all individuals and 66% of the biomass. Most of the major groups peaked in late spring/summer, but some peaked in early spring and fall. With the exception of nematodes, mean annual densities varied from two-fold to twelve-fold at a given station. Harpacticoids, tardigrades, and ostracods tended to be …

The Effects Of Limited Food Availability On The Striped Bass Fishery In Lake Mead, John R. Baker, Larry J. Paulson

Publications (WR)

The original range of striped bass (Morone saxatilis) was along the Atlantic Coast. They were introduced into the lower Sacramento River in 1879 and are now also found along the Pacific Coast. A landlocked striped bass fishery was established in Santee-Cooper Reservoir, South Carolina, in 1954, and they have since been introduced into numerous other reservoirs, including Lake Havasu, Lake Mead and Lake Powell on the Colorado River. Striped bass were introduced into Lake Mead in 1969 in response to declines in the largemouth bass (Micropterus salmoides) fishery that occurred during the 1960s and in order to further utilize the …
