Colonization Of An Abandoned Orchard By Pine Voles (Microtus Pinetorum), Jack A. Cranford, J. Harrison, T. L. Derting

Eastern Pine and Meadow Vole Symposia

Habitat selection by pine voles (Microtus pinetorum) has been attributed to cover density (Goertz, 1971; Paul, 1970) soil condition (Benton, 1955; Fisher and Anthony, 1980), and food resources (Noffsinger, 1976; Paul, 1970). Goertz (1971) reported that pine voles were distributed in diverse habitats, but there was a close correlation with height and diversity of grass. Miller and Getz (1969) found populations in sloping upland woods, Benton (1955) in dry woods, and Paul (1970) in hardwood slopes with a close correlation between distribution and amount of ground cover. Soil type has been examined by Benton (1955) and Fisher and …

Effects Of Tastants On Caching, Gnawing, Grooming And Taste Aversions In Pine Voles (Microtus Pinetorum) And Meadow Voles (M. Pennsylvanicus), Lynette A. Geyer, Christine Kornet

Eastern Pine and Meadow Vole Symposia

Several behaviors of pine and meadow voles were studied, specifically those affecting the role of taste in ingestion. These behaviors include: 1) caching, 2) gnawing, 3) grooming, and 4) taste aversions.

Male pine voles cached more than females, particularly when housed with females. Solitary females more than those housed in mixed sex pairs. When presented with peanuts and pine dowels in one-hour tests, pine voles cached peanuts first; the addition of flavorants did not affect the sequence in which they were cached. In six-hour tests, however, sucrose— and oil-soaked items were cached first.

Gnawing by pine voles, like caching, was …

Comparison Of Sampling Designs For Vole Population Studies, Donna Bruns Stockrahm, Jay Mcaninch, John D. Harder

Eastern Pine and Meadow Vole Symposia

In the summer of 1980 we initiated a large-scale vole population study in the lower Hudson Valley of New York and had questions regarding trapping designs and sampling procedures. Would samples reflect populations as they occurred in the orchard or would results merely be artifacts of the trapping design?

Renzulli et a1. (1980) examined how time interval between trapping periods, trap spacing, and grid size affected demographic estimates in meadow voles, Microtus pennsylvanicus, in non-orchard habitats. In other small mammal studies conducted in non-orchard habitats, 2 traps per station are often utilized to avoid the exclusion of animals or …

Survey Of Pine Vole Activity In Apple Orchards Near Roanoke, Virginia, Greg K. Yarrow

Eastern Pine and Meadow Vole Symposia

A survey of pine vole activity in apple orchards around the Roanoke, Virginia area was made in conjunction with current trapping efforts involving pine vole research. A total of 60 orchards were examined and subjectively ranked according to pine vole activity. At least 10% of the trees in each orchard were examined for signs of possible activity.

Water Metabolism In The Pine Vole, Pitymys Pinetorum, Donald H. Rhodes, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Orchard substrates, in general, provide excellent conditions for pine vole (Pitymys pinetorum) growth and reproduction as indicated by the distribution and abundance of pine voles within orchard situations in the eastern United States (Gourley and Richmond, 1972). However, the specific characteristics which are attractive to pine voles and facilitate their proliferation are poorly understood. The basis for selection of any particular habitat component by the pine vole is in large part a function of the vole's physiological requirements, because the physiological needs of the animals must be met by appropriate habitat resources. Thus, information on specific habitat parameters …

Vole Damage And Control Methods In Ontario Orchards, Ronald J. Brooks, Lin Schwarzkopf

Eastern Pine and Meadow Vole Symposia

In Ontario, herbivorous mammals inflict extensive damage upon fruit tree ocrchards and hardwood plantations (Radvanyi 1974 a, b; C. Dufault pers. commun., Hikichi pers. commun.). Nevertheless, surprisingly little research has been directed toward reduction or control of this damage and, therefore, growers continue to suffer substantial annual economic losses. Ontario appears to offer no specific guidelines to assist growers in developing effective long-term control programs for mammalian pests in their orchards. Recommended methods of control are limited to brief, general pamphlets most of which have shown little substantive change over the past few decades. There have been virtually no experimental …

Effect Of Photoperiod On Activity Patterns In Pine Voles (Microtus Pinetorum), Jack A. Cranford

Eastern Pine and Meadow Vole Symposia

Light is an environmental variable which has considerable effect on small mammal activity patterns. This constantly repeating 24 hour signal provides information on a daily basis and has been shown to synchronize all physiological patterns in an animals existence. Laboratory studies have shown that pine voles are slightly nocturnal (Pearson, 1947) or confined their activity to the hours of twilight and darkness (Werner, 1951). Both authors indicate that activity occurs in bouts of about 1 hour duration followed by an hour of rest. Benton (1955) observed from trapping that more activity occurred at night but cautioned that due to the …

Progress And Prospect Of A Bioenergetic Simulation Model Of Pine Vole Populations, John F. Coyle, Kevin C. Jordan, Alan R. Tipton, Roy L. Kirkpatrick

Eastern Pine and Meadow Vole Symposia

As reported previously (Coyle and Tipton 1980), we have been engaged in the development of a computerized system which outlines the basic demographic features of a pine vole population. The system, when complete, will hopefully contain four subsystems (biological, spatial, control and economic). This paper will discuss the biological submodel, its development and validity, and prospects for its future.

Meadow And Pine Vole Control I N 1980 Field Plots, Ross E. Byers, Mark H. Merson

Eastern Pine and Meadow Vole Symposia

Broadcast treatments of Volak (Brodifacoum), Rozol (Chlorophacinone), ZP Rodent Bait AG, and Ramik-Brown (Diphacinone) gave excellent to good control of voles in decreasing order of effectiveness. A saccharin formulation of Ramik-Brown or doubling the concentration of diphacinone to 0.01% did not result in any additional control over the current formulation. Hand placement of ZP Rodent Bait AG at 1 to 3 lbs/A gave excellent control of voles. Place packs of ZP Rodent Bait AG were not opened at all sites, however, residual activity from apple activity data indicated that this product gave excellent control. Additional field and laboratory evaluations were …

Social Behavior And Activity Patterns Of Meadow Voles In Relation To Seasonal Change And Snow Cover, Ronald J. Brooks, A. Bruce Webster

Eastern Pine and Meadow Vole Symposia

Activity and social behavior of free-ranging meadow voles (Microtus pennsylvanicus) were examined in summer, fall, and winter using capture-recapture and radiotelemetry. The composition of our study population changed from predominantly reproductively-active (RA) voles in summer and fall to entirely non-reproductively-active (NR) voles in winter. RA males had larger activity areas than RA females. Activity areas of RA females did not overlap with those of other RA females, but activity areas of RA males overlapped extensively with those of both RA males and RA females. However, any contact among RA voles was rare, unless females were estrous. NR voles …

Antiphosphocholine Antibodies Found In Normal Mouse Serum Are Protective Against Intravenous Infection With Type 3 Streptococcus Pneumoniae, David E. Briles, Moon Nahm, Kenneth Schroer, Joseph Davie, Phillip Baker, John Kearney, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

Although it has been clearly demonstrated that antibodies to pneumococcal capsules are protective in both mice and men (1, 2), the protective properties of antibodies to other pneumococcal constituents have been less well investigated. In the present report we describe results indicating that naturally occurring antibodies binding with the phosphocholine (PC) determinant of the pneumococcal cell wall C-carbohydrate (3) are important in the protection of mice from experimental pneumococcal infections.

Through The Trap Door Darkly: Nebraska Exemption Policy And The Bankruptcy Reform Act Of 1978, Richard F. Duncan

Nebraska College of Law: Faculty Publications

The Bankruptcy Reform Act establishes a somewhat disingenuous exemption policy that first creates, and then allows the individual states to nullify, uniform federal bankruptcy exemptions. The State of Nebraska has chosen to opt out of the federal exemption scheme thereupon assuming a continuing moral obligation to ensure that its exemption policy does not deny Nebraska debtors the fresh start following bankruptcy to which they are entitled. The Unicameral should undertake an immediate reconsideration of Nebraska exemption law with a view to possible elimination of the homestead exemption in favor of an expanded exemption in lieu of homestead to be available …

G81-574 Reproductive Diseases In Cattle, Duane Rice

University of Nebraska-Lincoln Extension: Historical Materials

The reproductive diseases mentioned in this NebGuide comprise some of the more common problems confronting the cattle industry today.

Although many advances have been made in controlling reproductive diseases in cattle, serious losses are still common. These losses can be reduced by recognizing the diseases and following the proper management recommendations that are available today. Nearly 50 percent of reproductive failure in cattle is due to infectious diseases, and there are vaccines available that can prevent some of these. Management recommendations may include: 1) vaccines, 2) general sanitation, 3) artificial insemination (AI) or, if a problem is already present, 4) …

Effectiveness Of Progeny Test Multiple-Trait Index Selection For Field Performance Of Strain-Cross Layers. I. Estimated Responses, T. S. Kashyap, G. E. Dickerson, G. L. Bennett

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Selection for egg production and egg quality traits in five Leghorn strains was based on pedigreed strain-cross (TX) progeny performance. About 24,000 TX pullets from 400 sires and 2400 dams were tested at 20 to 40 locations each year from 1956 through 1969. The TX pullet performance averages for 16 traits were combined in a linear index to evaluate sires in male lines and dams in female lines. Dams in male lines and sires in female lines were evaluated on the basis of full-sibs' progeny. Selection emphasis was primarily on rate of lay, viability, and egg size and secondarily on …

Streptococcal Infections Of Fishes, G. L. Bullock

United States Fish and Wildlife Service: Publications

Streptococcosis is a septicemic disease that affects both freshwater and saltwater fishes; it was first reported in rainbow trout, Salmo gairdneri (Hoshino et al. 1958). Additional outbreaks have since been described in cultured golden shiners (Notemigonus crysoleucas), yellowtails (Sepiola quinqueradiata), and eels (Anguilla japonious) , and in a variety of feral saltwater fishes.

Bacterial Gill Disease Of Freshwater Fishes, S. F. Snieszko

United States Fish and Wildlife Service: Publications

Bacterial gill disease (BGD) was first described by Davis (1926, 1927), who observed it in fry and fingerling brook trout (Salvelinus fontinalis) and rainbow trout (Salmo gairdneri) in hatcheries in Vermont. The affected trout were kept in dirt-bottom ponds and were not crowded; , daily mortalities were very low. Mortalities rapidly increased when the water temperature increased and diminished when the temperature decreased. Examination of the diseased trout revealed clubbing of gill filaments. In microscopic examination of wet mounts of the filaments" Davis found that the gill surface was covered with closely adhering strands of long, …

Giving-Up As A Poisson Process: The Departure Decision Of The Green Lacewing, Alan B. Bond

Alan Bond Publications

Predators that forage for aggregated prey appear to require a decision rule for determining the point at which to discontinue their search in a given prey patch and move on to another. Although the optimum rule depends heavily on features of the searching behavior of the predator and the distribution of the prey (Oaten 1977), most previous authors have assumed that the decision must involve an assessment of the capture rate within a patch and a comparison with the mean capture rate in the environment as a whole (Krebs 1978). When the perceived quality of the given patch becomes significantly …

Chinook Climates And Plains Peoples, Reid A. Bryson

Great Plains Quarterly (through 2013)

Changes in climate are major factors shaping the history of human occupance in the Great Plains region. Although Americans have often acted as though climates are fixed, the record indicates that in the past the climate of the Great Plains has changed drastically over relatively short periods of time. In order to acquire some understanding of what the Great Plains climate may become in the future and how human society may prepare for it, we must first comprehend what it was at various times in the past.
