Remembrance Of Places Lasts: Proactive Inhibition And Patterns Of Choice In Rat Spatial Memory, William A. Roberts, Robert H.I. Dale

Scholarship and Professional Work - LAS

A series of experiments was carried out to evaluate the notion that rats given a sequence of massed daily trials on the radial maze reset working memory at the end of each trial by deleting its contents. Although curves presented by D. S. Olton [Scientific American, 1977, 236, 82-98: In S. H. Hulse, H. Fowler, & W. K. Honig (Eds.), Cognitive processes in animal behavior, 1978, Hillsdale, N.J.: Erlbaum] show that rats return to errorless performance at the beginning of each trial after the first, the fact that accuracy falls less rapidly over choices on Trial 1 …

Reproduction In A Nebraska Sandhills Population Of The Northern Prairie Lizard Sceloporus Undulatus Garmani, Royce E. Ballinger, Dale L. Droge, Steven M. Jones

Papers in Herpetology

The reproductive cycle of Sceloporus undulatus was studied in western Nebraska. Females mature in the 1st year following hatching at a size of 45 mm SVL. Two clutches averaging 5.5 eggs each are produced. Egg sizes are similar to other grassland populations and contain approximately 650 g-cal. per egg. Egg weight to body weight ratios of 0.33 were the highest which have been reported for any S. undulatus population. Variation in life history characteristics within and between grassland and eastern woodland habitat types are explicable given a knowledge of the growing season, predation intensity and demographic environment.

Crossbreeding In Swine: Experimental Results, Rodger K. Johnson

Department of Animal Science: Faculty Publications

A review of recent swine crossbreeding experiments is presented and integrated with earlier work. Variation among experiments in observed heterosis for specific crosses was large for reproduction and sow productivity traits. However, standard errors of estimates were also large. It seems likely that heterosis, expressed in absolute values or in percentage units, is different for specific crosses. It is unclear whether these differences are large enough to warrant the use of unique parameter values for comparisons of alternate mating systems. In addition to average heterosis values, average direct and maternal genetic effects are given.

Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis

Biological Sciences Theses & Dissertations

Duck plague virus causes a hemorrhagic disease affecting the family Anatidae, resulting in 60-80% mortality in captive flocks. Plaque and neutralization assays for Anatid herpesvirus (AHV) require 5-10 days for completion and are restricted by the seasonal availability of fertile duck eggs. The enzyme linked innnunosorbent assay (ELISA) is rapid and specific and avoids the use of living cells. The Holland strain of AHV was grown on duck embryo fibroblasts and purified by banding on CsCl gradients. The resulting virus was used to raise antisera in prebled New Zealand white male rabbits. Antibody production was confirmed in double diffusion plates …

The Seasonality Of Occurrence Of Larval And Juvenile Sciaenids In A Virginia Seaside Estuary, James Howard Cowan Jr.

Biological Sciences Theses & Dissertations

The seasonality of occurrence and relative abundance of larval and juvenile fishes, particularly members of the family Sciaenidae, from a Virginia seaside estuary were determined from ichthyoplankton and trawl collections made from March 1979 to March 1980.

The larvae of 20 species distributed among 15 families were identified from the ichthyoplankton. Larvae of the bay anchovy, Anchoa mitchilli, and the Atlantic silverside, Menidia menidia, dominated the samples and made up 57 and 34%, respectively, of all larvae collected. Peak occurrence began in May and continued through August. Fish larvae were present in the study area all year.

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 …

Herpetofauna Of Mormon Island Preserve Hall County, Nebraska, Royce E. Ballinger, Steven M. Jones, J. W. Nietfeldt

Papers in Herpetology

Introduction: Studies of reptiles and amphibians in the grasslands of North America have primarily concerned the compilation of state faunal lists (e.g. Smith 1956, Hudson 1942, Webb 1970, Wheeler and Wheeler 1966). There have been a large number of reports on range extensions to augment this basic data. With the exception of the extensive studies by Fitch (1954, 1956, 1958, 1960, 1963) primarily on reptiles and Bragg (1940a, 1940b, 1943, 1953) primarily on anurans, the ecology of the herpetiles of the grasslands are not well studied. Lynch (1978) provided an excellent analysis of the ecological distributions of the leopard frogs …

Wintering Bald Eagles At Southwest Nebraska Reservoirs, David E. Busch

Nebraska Bird Review

As a part of Water and Power Resources Service (formerly Bureau of Reclamation) compliance with endangered species mandates, a study of Bald Eagle use of Lower Missouri Region reservoirs was initiated during the winter of 1979. The author, headquartered in McCook, surveyed a number of reservoirs in Kansas and Nebraska, including Nebraska's four southwest reservoirs.

While wintering Bald Eagles on the Platte River, Harlan County Reservoir, and the Lewis and Clark Lake area have been the subjects of previous studies, the southwest reservoirs have received little such attention. Since wintering Eagle populations at these four reservoirs are relatively low, this …

MISSISSIPPI KITE. At 3:30 p.m. 7 September 1980 Alan Grenon and I observed a Mississippi Kite from the back porch of our house, which is several meters south of Fontenelle Forest and about 1 km. west of the Missouri River, overlooking the flood plain. The bird was coming from the east, about 5 m. above the trees. The flight was extremely buoyant and smooth, rather like that of a light-bodied gull or swallow. When it was above us it began to glide in circles, just above the trees. From time to time it reached with its head for its feet, …

Where Have All The Stripers Gone?: An Analysis Of The Decline In The East Coast Striped Bass Fishery, Anthony P. Chatowsky

Marine Affairs Theses and Major Papers

Beginning in 1975 striped bass sports fishermen noticed a decrease in fish around. This decline was cause for alarm in 1977 when few striped bass were caught from shore. Commercial catch statistics showed that in 1973, 13,504,000 pounds of bass were landed. In 1979 the poundage was 3,492,000, a significant drop of 74%. This led to the development of state and regional striped bass advisory committees, an N.M.F.S. and U.S. Fish and Wildlife Emergency Action Plan and Congressional appropriation of 4.7 million dollars in 1979 to study the problem. The problem is multifactored and solutions lie in consistent coastal management …

The Use Of Linear Measurements For Determining Growth Rate & Size In Cattle, C. Norman Mcglohon

Masters Theses & Specialist Projects

The calves born in the 1979 and 1980 calf crops at Sam Sells and Sons' Polled Hereford Farm in Moultrie, Georgia, were used in a study comparing immature body measurements with subsequent growth. The measurements taken at birth included weight, front leg length, front cannon bone length, and rear cannon bone length. In addition, hip height was measured at one hundred days, seven months, and twelve months of age. Weight was taken at seven months, twelve months and fifteen months of age.

The data were analyzed in four groups according to year of birth and sex. Coefficients of correlation were …

Shade Management In Subtropical Environment For Milk Yield And Composition In Holstein And Jersey Cows, R. J. Collier, R. M. Eley, A. K. Sharma, R. M. Pereira, D. E. Buffington

Management and Monitoring of Farm Animals Collection

Forty-eight cows were assigned randomly to shade (15 Holsteins, 8 Jerseys) or no shade (16 Holsteins, 9 Jerseys) for 102 days beginning 12 June 1977 to examine effects of solar heat load on milk yield and composition. Rectal temperatures, respiration rates, and rumen contractions/min were monitored between 1200 and 1700 h on 20 randomly selected days. Morning and evening milk weights were recorded daily. Once weekly, morning and evening milk samples were collected from each cow and analyzed for fat, protein, acidity, freezing point depression, and somatic cell number. Black Globe temperature, rectal temperature, and respiration rate were elevated in …

Seasonal Temperature Preference Of Adult Mountain Whitefish, Prosopium Williamsoni, Jean M. Ihnat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Temperatures selected seasonally by adult mountain whitefish were measured in the laboratory in a horizontal gradient. Final preferendum estimates, based on acute (3-hour) preference tests conducted with fish acclimated to 5, 10, and 15 C each season, were 17.7 C (pre-spawning), 11.9 C (post-spawning), 9.9 C (winter), and 16.3 C (spring). Seasonal influence on temperature selection was evident on the basis of differences in final preferenda, covariance analysis of responses of laboratory-acclimated fish, and temperature selection by fish held at ambient river temperatures. Post-spawning and winter groups selected lower temperatures than did pre-spawning and spring groups. Pre-spawning fish selected temperatures …

Some Morphological And Chemical Responses Of Blackbrush (Coleogyne Ramosissima) To Goat Browsing: Influences On Dietary Blackbrush Selection By Goats And Cattle, Frederick D. Provenza

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Domestic goats were used to modify the growth form of blackbrush, a spinescent shrub occurring in nearly monospecific stands on several million hectares of rangeland in the southwestern United States. The objective of this research was to evaluate goat browsing as a means of improving these rangelands for cattle. Winter goat browsing stimulated spring twig growth from basal and axillary buds which resulted in increased production.

Twig production by heavily browsed plants (>95 percent removal of current season's twigs) was a function of precipitation, soil depth, branch location on the plant, and period of rest after browsing. As precipitation …
