Sandhill Cranes And The Platte River, Gary L. Krapu, Kenneth J. Reinecke, Charles R. Frith

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The waters of many western rivers have been diverted by man for irrigation and other consumptive uses (Ohmart et al. 1977, Johnson 1978). As flows in certain rivers diminished precipitously during this century, numerous conflicts have arisen brought on by changes affecting various interests. The Platte River is such an example. With approximately 69 percent of the annual flows destined for the Platte now removed upstream (Kroonemeyer 1979) and additional projects proposed that would utilize remaining flows, intense competition and widespread concern have developed among the factions relying on the river's flows to meet their needs.

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf

Avian Cognition Papers

An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.

The Effect Of Artificially Extended Photoperiod During Lactation On Maternal Performance Of The Sow, John W. Mabry, Fred L. Cunningham, Robert R. Kraeling, George B. Rampacek

United States Department of Agriculture Wildlife Services: Staff Publications

A 20-stall farrowing facility was partitioned into two separate rooms of 10 stalls each so that photoperiod could be controlled. In addition, temperature and air movement were equalized in the two rooms. The two light regimens utilized were 8 h light: 16 h dark, and 16 h light:8 h dark. A total of 26 sows in two replicates were used. Females were moved into the facility on d 103 -+2 of pregnancy, litters were equalized at birth and weaning was at 28 d of age. Traits evaluated included litter size at birth and weaning, 21-d pig and litter weights, milk …

The Ecology Of Mutualism, Douglas H. Boucher, Sam James, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Elementary ecology texts tell us that organisms interact in three fundamen­ tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on. Terms that may be considered synonyms, in whole or part, are symbiosis, commensalism, cooperation, protocooperation, mutual aid, facilitation, reciprocal altruism, and entraide. We use the term mutual­ism, defined as "an interaction between species that is beneficial to both," since it has both historical priority (311) and general currency. Symbiosis is "the living together of two organisms in close association," and …

Deer Social Organization And Wolf Predation In Northeastern Minnesota, Michael E. Nelson, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The white-tailed deer Odocoileus virginianus has been subject to intensive research and management, yet we are just beginning to understand its social organization. Little is known about home range formation, migration, social bonds, and traditions in this deer, what functions they serve, and what selective forces have affected them.

Predation by wolves Canis lupus, in particular, has not been examined as a factor in deer evolution, yet the intimate interactions between deer and wolf through the millennia no doubt strongly influenced major morphological and behavioral adaptations in both species. It is a reasonable assumption that wolf predation has been …

The Platte River Ecology Study: Special Research Report', Northern Prairie Wildlife Research Center

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Each spring about 80%of the sandhill cranes in North America stop for several weeks in the Platte and North Platte River Valleys of Nebraska while en route to breeding grounds in Canada, Alaska, and the Soviet Union. This concentration of cranes is unparalleled in North America and these sites represent the principal spring staging areas for the midcontinent population. Large numbers of waterfowl, numerous bald eagles, whooping cranes, and many other species also use the area.

Recent changes in habitat conditions along the Platte and North Platte Rivers have prompted concern for the welfare of sandhill cranes and other migratory …

Effect Of Maternal Dietary Energy Source On Glucose Homeostasis, Liver Glycogen And Carcass Lipid In The Neonatal Pig, R. D. Boyd, B. D. Moser, A. J. Lewis, E. R. Peo Jr., R. K. Johnson, R. D. Nimmo

Department of Animal Science: Faculty Publications

Two experiments were conducted to determine the effects of supplementary dietary energy (carbohydrate versus fat) fed to sows during late gestation on energy storage and glucose homeostasis in neonatal pigs. In the first experiment, 28 crossbred sows received one of two dietary treatments that were initiated on day 100 of gestation. The control group was fed daily 1.82 kg of a corn-soybean meal-based diet plus an additional .18 kg of cornstarch. Their counterparts were fed 1.82 kg of a cornsoybean meal diet containing 8% bleachable fancy tallow. The effect of maternal dietary energy source during late gestation on glucose homeostasis …

Frontier Subsistence: An Example Of Nineteenth Century Fur Trade Food Procurement, Leslie A. Perry

Department of Anthropology: Theses and Student Research

The area of Frontier subsistence strategies holds considerable potential for explaining Euroamerican adaptation in North America between A.D. 1500 and 1900. This thesis examines the interrelationships between food procurement activities of a nineteenth century northern Plains fur trade post, Fort Union, and its environmental and economic settings. The subsistence strategy identified from ethnohistorical, archival, and archeological data illustrates the way in which inhabitants of the fort coped with a variable local environment and the demands of the fur trade. Evaluation of the effectiveness of the post's subsistence strategy indicates that both the subsistence strategy and the economic base of the …

Genetic And Phenotypic Relationships Between Pubertal And Growth Characteristics Of Gilts, L. K. Hutchens, R. L. Hintz, R. K. Johnson

Department of Animal Science: Faculty Publications

Data on 737 crossbred and purebred gilts were used to obtain heritability estimates for age at puberty (AGEPUB) and weight at puberty (WTPUB) and their genetic and phenotypic correlations with birth weight (BW), weaning weight (WW), postweaning daily gain (ADG), adjusted age at 90.7 kg (AGE) and adjusted backfat at 90.7 kg (BF). The heritability estimates for AGEPUB were low to moderate (.19 and .40, based upon paternal and maternal half-sib estimates, respectively.) The genetic (rg) and phenotypic (rp) correlations between AGEPUB and BW (r_g = -.07; r_p = -.09), WW (r_g = -.25; r_p = …

Digestibility And Nutritional Quality Of Apple Tree Roots And Other Orchard Forages Of The Pine Vole, F. A. Servello, R. L. Kirkpatrick, K. E. Webb Jr.

Eastern Pine and Meadow Vole Symposia

Analysis of the seasonal food habits of pine voles (Microtus pinetorum) by Cengel et a1. (1978) revealed that apple tree root consumption occurs only during winter months. Increased root consumption in the winter has been postulated to be due to a decrease in the quantity and quality of other foods in orchards. However, the normal translocation of carbohydrates into the root systems of trees during the dormant season may improve the quality of apple tree roots as a food source for voles. One objective of the pine vole nutrition studies at Virginia Polytechnic Institute and State University is …

Growth And Development Rates Of Microtus Pinetorum Under Different Photoperiods, T. L. Derting, J. A. Cransford

Eastern Pine and Meadow Vole Symposia

Photo-period and nutrition are important variables affecting reproductive activity and growth in many rodents. Field and laboratory studies indicate that long photo-period (spring-summer) cause Increased growth while short photo-periods (fall-winter) inhibit these processes. In the montane vole (Microtus montanus) recently weaned animals gain weight at a much lower rate under short photo-periods or in total darkness than under long photo-periods (Vaughan et al., 1973; Peterborg, 1978). Adult M. montanus had more offspring and larger mean litter sizes under LD 18:6 than LD 6:18 (Pinter & Negus, 1965). Similarly, long (LD 16:8) or increasing photo-periods stimulated the onset of …

The meeting was intended to create a problem solving atmosphere in which growers; various governmental agencies such as EPA, USDA, USDI; the chemical industry; and university personnel could observe the cur¬rent thrusts of research and extension programs and their potential impact on future …

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 …

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.

The Role Of Nutrient Reserves In Mallard Reproduction, Gary Krapu

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Mallard (Arias platyrhynchos) populations breeding in temperate North America obtain a significant part of the energy and lipid requirements of reproduction at sites occupied prior to arrival on the breeding grounds. Protein for egg formation, however, is obtained principally from the diet during the nesting period. Both sexes arrive heavy and fat in North Dakota but experience substantial weight loss and lipid depletion during the nesting cycle. Weight loss is most pronounced among females and averages 25% from prelaying to late incubation. Body weights of both sexes are positively correlated with carcass lipid content. The paired male draws …
