Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways
Revised Checklist Of North American Mammals North Of Mexico, 1979, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Faunal checklists provide useful ready references for many kinds of endeavors, both in the laboratory and in the field, and are particularly helpful to students. Since publication more than four years ago of a "Revised checklist of North American mammals north of Mexico" (Jones et al., 1975), demand for that list has exceeded the supply set aside for general distribution; additionally, systematic studies of mammals published since 1974 necessitate changes in the list. Primarily for these reasons, a newly revised checklist of mammalian species occurring in the Nearctic to the north of Mexico is here presented. As in this and …
Variation In Pappogeomys Castanops (Geomyidae) On The Llano Estacado Of Texas And New Mexico, Robert C. Dowler, Hugh H. Genoways
Variation In Pappogeomys Castanops (Geomyidae) On The Llano Estacado Of Texas And New Mexico, Robert C. Dowler, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Nongeographic and geographic variation in the yellow-cheeked pocket gopher, Pappogeomys castanops, were analyzed in specimens collected in northwestern Texas and eastern New Mexico. Univariate and multivariate methods of analysis were utilized to assess variation in morphometric characters among 12 samples of P. castanops. Because of significant variation with age, only adult specimens were used in analyses. Adult males were significantly larger than females in all 13 characters studied. Our analyses of geographic variation reveal that those specimens previously assigned to the subspecies P. c. simulans are not sufficiently distinct to warrant subspecific designation.
Predation Of Upland Game And Its Management, Roger Wells
Predation Of Upland Game And Its Management, Roger Wells
Great Plains Wildlife Damage Control Workshop Proceedings
There is probably no greater topic that elicits greater emotion in public wildlife discussions than that of predation. A variety of groups each with their own particular special interest surround the topic.
Some advocate complete protection of predators on the premise that their activities merely result in a "balance of nature." The opposite viewpoint argue just as strongly for the total elimination of Predators of valued wildlife in order to have greater number for man's enjoyment.

Cyanogenesis In Indiangrass Seedlings, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel
Cyanogenesis In Indiangrass Seedlings, Francis A. Haskins, H. J. Gorz, Kenneth P. Vogel
Department of Agronomy and Horticulture: Faculty Publications
In a study of seedlings of 72 entries representing 39 species, 14 genera, and 2 tribes of grasses, only entries of the genus Sorghastrum were found to contain the cyanogenic glucoside, dhurrin [(S)-p-hydroxymandelonitrile β-D-glucopyranoside]. Dhurrin was found in seedlings of each of the 10 entries of indiangrass [Sorghastrum mutans (L) Nash] and the three entries of S. pellitum.
Seedlings of five indiangrass cultivars were assayed for dhurrin concentration. Levels expressed as HCN potential (HCN-p) ranged from about 900 ppm for 'Holt' to about 1,200 ppm for 'Llano' and 'Oto'.
Further studies with Oto seedlings indicated that …

Sublethal Stress In Escherichia-Coli - Function Of Salinity, I. C. Anderson, Mw Rhodes, H Kator
VIMS Articles
Sublethal stress in Escherichia coli was detected in various test media after exposure (in vitro) to seawater of various salinities. Stress was measured with an electrochemical detection technique and a,-galactosidase assay. Test media included EC medium, medium A-1, and tryptic soy broth modified to contain lactose for /?-galactosidase assay experiments. Stress was defined as the difference between a predicted electrochemical response time calculated for unstarved cells from a standard curve and the observed electrochemical response time for cells starved in seawater. The higher the salinity, the greater the stress for all test media examined. Stress was most pronounced in EC …

Effects Of Fecally Contaminated Feed By Starlings On Growing Swine & Mice, Pat Schuster
Effects Of Fecally Contaminated Feed By Starlings On Growing Swine & Mice, Pat Schuster
Masters Theses & Specialist Projects
The effects of feed contamination by droppings of starlings (Sturnis vulgaris) on certain growth parameters in swine (Sus scrofa) were measured from January 25 to March 1, 1979 at the Western Kentucky University farm. Weight gain, feed-conversion efficiency and feed rejection by swine fed varying levels of contaminated feed were analyzed and found to be non-significant at the fecal concentrations used.
Laboratory mice (Mus musculus) were fed varying concentrations of starling feces in standard mouse chow; weight gain, feed-conversion efficiency and feed rejection were measured. At 0%, 10%, 25% and 50% concentrations, significant differences …
A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer
A Water Quality Modeling Study Of Lynnhaven Bay, Virginia, A. Y. Kuo, P. V. Hyer
Reports
The City of Virginia Beach has proposed channel dredging in the Eastern Branch of the Lynnhaven Bay for the purposes of recreations and drainage improvement. It is therefore necessary to examine the possible environmental results of such a project. This environmental assessment is complicated by another proposal to modify the Lynnhaven system. The U.S. Army Corps of Engineers has proposed adding a second canal leading to the Eastern Branch, in order to reduce flood damage. This canal project would affect the Lynnhaven system by increasing nonpoint sources of pollution and by increasing the tidal prism. The water quality consequences of …

Economic Implications Of Alternative Dry-Bulk Fertilizer Supply Systems: A South-Central Nebraska Case Study, Mary Berglund, Dale G. Anderson
Economic Implications Of Alternative Dry-Bulk Fertilizer Supply Systems: A South-Central Nebraska Case Study, Mary Berglund, Dale G. Anderson
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This study analyzed the economic implications of alternative patterns of rail service for a case-study area in south-central Nebraska. Special attention was given to effects of branchline abandonments on the delivery system for dry-bulk fertilizer. The study was an extension of an earlier Nebraska track abandonment study which focused only on grain traffic. The purpose of the latest study was to establish the effect of including dry-bulk fertilizer, the major commodity moving into the area by rail, on the earlier results. The addition of fertilizer to the analysis did not appreciably change the outcome of the earlier grain-oriented study.
Concurrent Drinking By Pigeons On Fixed-Interval Reinforcement Schedules, Robert H.I. Dale
Concurrent Drinking By Pigeons On Fixed-Interval Reinforcement Schedules, Robert H.I. Dale
Scholarship and Professional Work - LAS
Three experienced pigeons were exposed to at least ten consecutive 100-min sessions on each of three food-reinforced fixed-interval (FI) schedules: FI 50-sec, FI 100-sec and FI 200-sec. Water was freely available. Drinking was largely confined to the first third of each fixed interval, and the mean sessional water intake was directly related to the food-reinforcement rate for each animal. The animals drank very quickly, i.e., 3-4 ml/sec, but the drinking bouts were brief, i.e., 0.8-1.4 sec, and infrequent, i.e., 2-5/hr. The parameters describing concurrent drinking in the pigeon are strikingly different from those describing rats’ drinking under similar reinforcement schedules, …

Reproductive performance of 12 11-month-old Yorkshire boars was determined during and after exposure to control or increased ambient temperatures. After 3 weeks adjustment at 23 C in temperature controlled chambers, six boars were heat stressed by exposure to 34.5 ± 1.0 C for 8 hr and 31.0 ± 1.0 C for 16 hr during each 24-hr period and six control boars were maintained at 23.0 ± 1.0 C for 11 weeks. All boars were subsequently exposed to 23 C for 6 weeks. Semen was collected twice weekly before, during and after heat stress and boars were naturally mated with gilts …

Eastern Wheatbelt Farm Economics, Peter Eckersley
Soil conservation survey collection
This booklet outlines the current cost structure and profitability of a farm in the eastern wheatbelt. Rather than being figures for an 'average farm', they reflect the use of practices widely recommended by the Department of Agriculture on a typical property in the area. This does not mean the Department of Agriculture believes every farm in the area should be run this way. The best way to run any particular farm depends on the resources and objectives of that farmer.

Significance Of Hemolytic Activity Of Some Radiation- Resistant Micrococci In Food, Ardyce Welch, R. Burt Maxcy
Significance Of Hemolytic Activity Of Some Radiation- Resistant Micrococci In Food, Ardyce Welch, R. Burt Maxcy
Department of Food Science and Technology: Faculty Publications
Micrococci resistant to 1 Mrad ofgamma radiation were isolated from irradiated chicken. Three isolates were hemolytic on blood agar plates and were selected for further study.Two other radiation-resistant micrococci, Micrococcus radiodurans and Micrococcus radiophilus, were included in the study because there is only a very limited amount of information regarding hemolytic activity of these organisms and their potential role of public health importance. Tests to determine hemolytic patterns, hemolytic activity of extracellular substances, leukocytic activity, presence of enzymes commonly associated with pathogenicity (coagulase, deoxyribonuclease, phosphatase), and pathogenicity for laboratory animals all suggested that the organisms would not be of …

A Description Of The Commercial Marine Fisheries Of Virginia, James Zaborski
A Description Of The Commercial Marine Fisheries Of Virginia, James Zaborski
Reports
The magnitude and valtte of the fisheries of Virginia are significant. Expansion of some fisheries since 1977 in conjunctio~ with rising prices for fishery products in general has increased the importance of this industry to the Commonwealth. Virginia's fisheries are varied, some segments of the industry such as the oyster fishery have been in existence since colonial days; others, such as the surf clam fishery, are relatively new. The size and composition of the different industries also differ widely. The menhaden fishery exempli~ies what might be termed corporate fishing while the blue crab fishery is conducted by numerous individual owner-operators. …
A Water Quality Study Of The Eastern Branch Of The Lynnhaven Bay, Virginia, Albert Y. Kuo, Paul V. Hyer
A Water Quality Study Of The Eastern Branch Of The Lynnhaven Bay, Virginia, Albert Y. Kuo, Paul V. Hyer
Reports
To alleviate the flooding in the drainage basin of the Lynnhaven River at Virginia Beach, Virginia, the U. S. Army Corps of Engineers has proposed to improve the waterways along the headwater of the river (House Document, 1976). The improvements include the widening and deepening of the existing canal, and the dredging of a new canal. As a result of the proposed project and the present rate of increase in area development, the freshwater runoff from the drainage basin and the tidal prism in the system are expected to increase. Since nonpoint sources are the only source of pollutants to …
