Gray Partridge Foraging Ecology In Eastern South Dakota, Jerry W. Hupp, John T. Ratti, Loren M. Smith Apr 1988

Gray Partridge Foraging Ecology In Eastern South Dakota, Jerry W. Hupp, John T. Ratti, Loren M. Smith

Great Basin Naturalist

We examined crop contents of 217 Gray Partridge (Perdix perdix) collected during a two-year period in eastern South Dakota. Row crop grains (corn, sunflowers) dominated late fall, winter, and spring diets. Small grains (oats, barley, wheat, rye) were rarely consumed although fields of small grains were widely available. During a severe winter when waste row crop grains were buried by snow, partridge consumed more leafy vegetation. Insects dominated the early summer diet, while foxtail (Setaria spp.) seeds were a major late summer and early fall food.

Monoterpene Concentrations In Litter And Soil Of Singleleaf Pinyon Woodlands Of The Western Great Basin, F. Martin Wilt, Glenn C. Miller, Richard L. Everett Apr 1988

Monoterpene Concentrations In Litter And Soil Of Singleleaf Pinyon Woodlands Of The Western Great Basin, F. Martin Wilt, Glenn C. Miller, Richard L. Everett

Great Basin Naturalist

Mean monoterpene content of singleleaf pinyon (Pinus monophylla [Torr.] Frem.) litter from stands growing on two soil series was 340 ± 310 ug/g air dry weight (adw). Individual monoterpene hydrocarbons suggested as potential allelopathic compounds occur in extremely small amounts, 0.5–1.10 ug/g adw. Mineral soils contained 50 times less total terpene, 6.6 ug/g ± 4.8 adw, than the litter immediately above. Results suggest that allelopathic effects would more likely occur in litter than mineral soil. These findings are substantiated by previous reports of decreased emergence and growth of herbaceous species in pinyon litter but not mineral soil.

Relationships Of Aspen (Populus Tremuloides) To Foraging Patterns Of Beaver (Castor Canadensis) In The Strawberry Valley Of Central Utah, William J. Masslich, Jack D. Brotherson, Rex G. Cates Apr 1988

Relationships Of Aspen (Populus Tremuloides) To Foraging Patterns Of Beaver (Castor Canadensis) In The Strawberry Valley Of Central Utah, William J. Masslich, Jack D. Brotherson, Rex G. Cates

Great Basin Naturalist

Eight study sites were examined in Strawberry Valley, Utah, to assess the response of aspen (Populus tremuloides Michx.) to cutting activities of beaver (Castor Canadensis Warren & Hall) and to determine patterns by which the animals utilize aspen stands. Sites utilized by beaver, along with adjacent control plots in mature, uncut aspen stands, were sampled. Age-class profiles of control plots were composed of a broad age distribution with trees ranging from 3 to 108 years old. Age-class profiles for aspen sprouts in areas previously used by beavers were composed of trees averaging seven years of age with a …

Effects Of Livestock Grazing Exlosure On Aquatic Macroinvertebrates In A Montane Stream, New Mexico, John N. Rinne Apr 1988

Effects Of Livestock Grazing Exlosure On Aquatic Macroinvertebrates In A Montane Stream, New Mexico, John N. Rinne

Great Basin Naturalist

Aquatic macroinvertebrate populations inhabiting reaches of a stream within areas excluded from livestock grazing for a decade were markedly different from those in grazed areas when density, biomass, biotic condition indices, and mean chi square indices of the two populations were compared. Increased densities and biomasses of more tolerant forms of macroinvertebrates were observed in grazed reaches. Because pretreatment data were not available, differences in macroinvertebrate populations and relative tolerances of taxa in grazed and ungrazed areas could be as easily attributed to linear changes in stream habitat as to removal of domestic livestock. Results of this study have implications …

Selection Of Big Sagebrush By Sage Grouse, Bruce L. Welch, Jordan C. Pederson, Ronald L. Rodriguez Apr 1988

Selection Of Big Sagebrush By Sage Grouse, Bruce L. Welch, Jordan C. Pederson, Ronald L. Rodriguez

Great Basin Naturalist

Feeding sites of wintering sage grouse (Centrocercus urophasianus) were located, one each in stands of three subspecies of big sagebrush (Artemisia tridentata: ssp. tridentata, basin; ssp. vaseyana, mountain; and ssp. Wyomingensis, Wyoming). Evidences of differential use of plants within subspecies were observed. Whole leaves from fed-on and nonfed-on big sagebrush plants were examined for intrasubspecies chemical comparisons of crude protein, phosphorus, in vitro digestibility, and monoterpenoids. No significant differences were detected except for in vitro digestibility of Wyoming fed-on and nonfed-on big sagebrush and monoterpenoid content of basin big sagebrush. Nutritive content of …

Time-Activity Budgets Of Drake Gadwall And Northern Shovelers On Industrial Cooling Ponds During Late Winter And Early Spring In Central Utah, G. Merrill Webb, J. D. Brotherson Apr 1988

Time-Activity Budgets Of Drake Gadwall And Northern Shovelers On Industrial Cooling Ponds During Late Winter And Early Spring In Central Utah, G. Merrill Webb, J. D. Brotherson

Great Basin Naturalist

Time-activity budgets of drake Gadwall and Northern Shoveler ducks were studied in the winter of 1985. Total duck numbers peaked in mid-March. Gadwall numbers increased from late January to mid-March and then declined, while Northern Shoveler numbers declined from late January to mid-February and then increased to mid-March before declining. Behavior categories considered in the time-activity budgets were flying, preening, swimming, courtship, feeding, and resting. Time allocated to these different activities varied for both duck species, with feeding being the only behavior pattern wherein differences were significant. Gadwalls spent 58% of their time feeding. Northern Shovelers only 26%. Possible reasons …

Field Observations Of Irbisia Pacifica (Hemiptera: Miridae): Feeding Behavior And Effects On Host Plant Growth, James D. Hansen Jan 1988

Field Observations Of Irbisia Pacifica (Hemiptera: Miridae): Feeding Behavior And Effects On Host Plant Growth, James D. Hansen

Great Basin Naturalist

The interaction between a grass-feeding mirid, Irbisia pacifica (Uhler), and plant growth of intermediate wheatgrass, Thinopyrum intermedium (Host) Barkw. & D. R. Dewey, was examined on a field site in northern Utah in 1985. With egg hatch beginning in April, the bug completed its life cycle within two months. Ovarian development was completed by 11 June, a week after all bugs had become adults. The proportion of feeding damage per leaf (35.1%) peaked on the seventh week of the twelve-week study (18 July). Green leaf area per tiller decreased initially from bug feeding and then continued to decrease because of …

Migrating Mormon Crickets, Anabrus Simplex (Orthoptera: Tettigoniidae), As Food For Stream Fishes, Harold M. Tyus, W. L. Minckley Jan 1988

Migrating Mormon Crickets, Anabrus Simplex (Orthoptera: Tettigoniidae), As Food For Stream Fishes, Harold M. Tyus, W. L. Minckley

Great Basin Naturalist

Migrating bands of Mormon crickets (Ananbrus simplex) were observed crossing the Green and Yampa rivers in Dinosaur National Monument, Colorado and Utah, in 1986 and 1987. Swimming crickets were swept downstream and eaten by four endemic and seven introduced fish species. Included were two endangered fishes, Colorado squawfish (Ptychocheilus lucius) and humpback chub (Gila cypha). Direct and indirect effects to aquatic food webs associated with application of pesticides for Mormon cricket control may pose a threat to these fishes and to man.

A Review Of Flea Collection Records From Onychomys Leucogaster With Observations On The Role Of Grasshopper Mice In The Epizoology Of Wild Rodent Plaque, Rex E. Thomas Jan 1988

A Review Of Flea Collection Records From Onychomys Leucogaster With Observations On The Role Of Grasshopper Mice In The Epizoology Of Wild Rodent Plaque, Rex E. Thomas

Great Basin Naturalist

Published records of fleas collected from the northern grasshopper mouse, Onychomys leucogaster, indicate that these mice have a great deal of intimate environmental contact with other rodents or their burrows. Fifty-seven species of fleas have been collected from the omnivorous grasshopper mouse. The range of this mouse overlaps much of the distribution of plague, Yersinia pestis, in the western United States; and nearly one-half of the flea species collected from O. leucogaster are known to be of importance in the epizoology of plague. This article discusses the importance of the association of fleas with a hospitable secondary host …

Seasonal Changes Of Selected Secondary Plant Products In Chrysothamnus Nauseosus Ssp. Turbinatus, D. F. Hegerhorst, R. B. Bhat, D. J. Weber, E. D. Mcarthur Jan 1988

Seasonal Changes Of Selected Secondary Plant Products In Chrysothamnus Nauseosus Ssp. Turbinatus, D. F. Hegerhorst, R. B. Bhat, D. J. Weber, E. D. Mcarthur

Great Basin Naturalist

Previously, physiological studies of rubber and resin production during the growing season of Chrysothamnus nausceosus ssp. turbinatus indicated a negative correlation between rubber and resin content. The resin was highest in the spring and lowest in the summer, whereas rubber was highest in the summer and lowest in the spring. Individual compounds were followed during the growing season to see if they correlated with the rubber or resin trend. The total compounds in the cyclohexane fraction followed the resin pattern. Individual compounds varied in their changes during the growing season. Limonene, for example, was negatively correlated with rubber production, whereas …

Psychology Among The Saints: The Development Of Behavioral Science At Brigham Young University, Bruce L. Brown, Mark K. Allen Jan 1988

Psychology Among The Saints: The Development Of Behavioral Science At Brigham Young University, Bruce L. Brown, Mark K. Allen

Faculty Publications

There was a strong interest in psychology at Brigham Young University at the turn of the century; the third president was a psychologist and a number of distinguished psychologists regularly visited the campus. An outstanding young scholar who was destined to become the only Mormon president of the American Psychological Association started a vigorous academic psychology program in those early years, but he left the university because of a controversy over his teachings. Psychology at Brigham Young University developed little from that time until the 1940s. The 1950s were a time of rapid growth and development, expansion of the faculty, …

Digital Neural Networks, Tony R. Martinez Jan 1988

Digital Neural Networks, Tony R. Martinez

Faculty Publications

Demands for applications requiring massive parallelism in symbolic environments have given rebirth to research in models labeled as neural networks. These models are made up of many simple nodes which are highly interconnected such that computation takes place as data flows amongst the nodes of the network. To present, most models have proposed nodes based on simple analog functions, where inputs are multiplied by weights and summed, the total then optionally being transformed by an arbitrary function at the node. Learning in these systems is accomplished by adjusting the weights on the input lines. This paper discusses the use of …

Aspects Of Bald Eagle Winter Behavior In Rush Valley Utah: A Telemetry Study, Neil B. Sabine Dec 1987

Aspects Of Bald Eagle Winter Behavior In Rush Valley Utah: A Telemetry Study, Neil B. Sabine

Theses and Dissertations

The diurnal behavior and nocturnal roosting patterns of 28 bald eagles outfitted with tail-mounted radios were investigated in Rush Valley, Utah between January and March 1982-1984. Casting analysis and feeding observations indicated the principal food source was jackrabbit carrion. Jackrabbit availability declined from 1982 to 1984 and eagles responded by; 1) roosting closer to feeding sites, 2) shifting from canyon to valley roosts, 3) arriving later at and departing earlier from roosts, 4) decreasing diurnal activity, and 5) decreasing residence time. Foraging efficiency appeared to be maximized by experienced eagles using familiar feeding areas and by naive birds monitoring their …
