An Annotated List Of The Vascular Plants Of Fontenelle Forest And Neale Woods In Eastern Nebraska, Marjorie Mueller Garabrandt

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

No detailed listing of the complete vascular flora of any woodland site along the Missouri River of east-central Nebraska has been published. This study provides a current annotated list of vascular flora at two private nature centers in the Omaha area, Fontenelle Forest and Neale Woods. Totaling about 644 hectares, the two preserves are located on loess bluffs adjacent to the Missouri River valley, with Fontenelle Forest also containing floodplain forest. A total of 597 species are distributed among 100 families and 331 genera between the two sites, representing approximately one-third of the known vascular flora for Nebraska. Comparisons are …

Systematics And Population Ecology Of Late Pleistocene Bighorn Sheep (Ovis Canadensis) Of Natural Trap Cave, Wyoming, Xiaoming Wang

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Large numbers of Late Pleistocene bighorn sheep (total counts of identifiable elements: 4,497) Ovis canadensis. are described from the Natural Trap Cave, northern Wyoming. The specimens consist of nearly-intact skulls and enough post-cranial materials to assemble several complete sheep skeletons. Most of the fossils yield radiocarbon dates from 12,000 to 21,000 BP, while the oldest are more than 110,000 years old as dated by the fission-track method on the volcanic ash. The specimens resemble modern bighorn sheep (Ovis canadensis) in having shallow lachrymal fossae and relatively wide rostra. in contrast to the Asian argali (Ovis ammon …

Ec88-116 Universal Soil Loss Equation: A Handbook For Nebraska Producers, A. J. Jones, D. Walters, W. G. Hance, Elbert C. Dickey, J.R. Culver

University of Nebraska-Lincoln Extension: Historical Materials

Tons of soil are lost from agricultural fields in Nebraska each year as a result of water erosion. The accelerated loss of topsoil reduces the availability of plant nutrients and water needed for optimum crop production. In addition, the eroded soil frequently moves into surface waters causing sediment to be deposited in streams and reservoirs and nutrients to be released into other biological systems. The purposes of this workbook are to provide an understandng of how soil erosion estimates are determined, to estimate erosion control resulting from numerous cropping systems, and to inform the producer of alternative practices which may …

A New Subspecies Of The Free-Tailed Bat, Molossops Greenhalli, From Western Mexico (Mammalia: Chiroptera), J. Knox Jones Jr., Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

In June of 1964, field parties from the Museum of Natural History, the University of Kansas, collected two specimens of a unique free-tailed bat in Mexico, one in the state of Guerrero and the other in Oaxaca. These proved to be the first specimens of Molossops greenhalli taken outside of Trinidad and the first bats of the genus to be reported from north of Panama. Subsequently, Percy L. Clifton obtained, in the state of Jalisco, three more individuals of M. greenhalli, including the first male from the North American mainland.

Comparison with material from Trinidad indicates that the Mexican …

Potential For Hydrocyanic Acid Poisoning Of Livestock By Indiangrass, Kenneth P. Vogel, H. J. Gorz, Francis A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

Hydrocyanic acid or prussic acid poisoning of livestock by sorghums [Sorghum bicolor (L.)Moench] and sudangrasses [Sorghum sudanese (Piper) Stapf] is caused by the digestive liberation of hydrocyanic acid (HCN) from the cyanogenic compound, dhurrin [(S)-p-hydroxymandelonitrile ,β-D-glucopyranoside] found in tissue of these plants. Recent research documented that dhurrin is also present in indiangrass [Sorghastrum nutans (L.) Nash] seed- lings. The purpose of this study was to determine the hydrocyanic acid potential (HCN-p) of forage from established stands of indiangrass. Five cultivars representative of indiangrass germplasm of the Great Plains were sampled during the growing season for 2 years …

Nebraska's Modified-Open-Front Farrowing Houses Design And Operation, Gerald R. Bodman, Donald G. Levis, Duane E. Reese

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Two modified-open-front non-mechanically ventilated farrowing houses with creep boxes were operated over a two year period. Annual energy requirements were in the range of 10.6 to 10.9 cents per crate per day. No adverse effects on pig performance were realized. In most instances pig performance exceeded national standards of excellent performance—survival rates in excess of 90% and 21-day pig weights of 5.9 to 6.8 kg (13 to 15 lb). The study verified that another alternative is available to producers who do not want additional mechanical equipment to operate and maintain.

The Glycoprotein Toxin Of Bacillus Thuringiensis Subsp. Israelensis Indicates A Lectinlike Receptor In The Larval Mosquito Gut, Ganapathy Muthukumar, Kenneth Nickerson

Papers in Microbiology

The mosquito-active protein crystals produced by Bacillus thuringiensis subsp. israelensis contain covalently attached aminosugars which are critical for their larvicidal activity. The 50% lethal concentrations toward Aedes aegypti larvae were increased up to 10-fold by mild periodate treatment, up to 40-fold by forming the protein crystals in the presence of tunicamycin, and up to 7-fold by the presence during the mosquito bioassays of N-acetylglucosamine or its trimer, triacetylchitotriose. Periodate-treated crystals and crystals formed in the presence of tunicamycin had greatly reduced binding capacities for wheat germ agglutinin, an Nacetylglucosamine- specific lectin. These results suggest that the B. thuringiensis subsp. …

Catecholamine Training Effects From Exercise Programs: A Bridge To Exercise-Temperament Relationships, Richard A. Dienstbier, Robert L. Laguardia,, Marc Barnes, Gerald Tharp, Richard J. Schmidt

Department of Psychology: Faculty Publications

Three studies were conducted to test whether a catecholamine training effect results from a long-term aerobic exercise program. Study 1 showed significant increases in urinary adrenaline and noradrenaline following moderate mental stress/challenge for male aerobics subjects after a semester of training. Control groups of nonexercisers and continuously in-condition marathoners showed no comparable pre- to post semester catecholamine increases. Male and female Aerobics subjects were contrasted with nonexercisers across a semester in Study 2; the hypothesis was confirmed that postsemester increases in catecholamines occurred only following an episode of mental challenges/stress, and not following base-rate-rest conditions. Under conditions of more active …

Controlling Blackbirds And Starlings At Winter Roosts Using Pa-14, J.F. Heisterberg, A.R. Stickley Jr., K.M. Garner, P.D. Foster Jr.

Eastern Wildlife Damage Control Conference: 3rd (1987)

The only EPA-registered chemical for lethal control of winter roosting blackbird (Icterinae) and European starling (Sturnus vulgaris) populations is Compound PA-14 Avian Lethal Agent (PA-14). Between 1978 and 1987, 39 PA-14 spray operations, 15 by helicopter and 24 by ground-based spray systems, have been conducted at 33 winter roosts in Kentucky, Tennessee, and Alabama. In-roost bird mortality for the aerial operations have been poor, averaging only 4% of the pretreatment roost populations or 114,000 birds killed per spray operation. Although very labor-intensive, a ground-based sprinkler system application method has proven much more successful, averaging 67% in-roost bird mortality …

The Future Of Wildlife Damage Control In An Urban Environment, Gary J. San Julian

Eastern Wildlife Damage Control Conference: 3rd (1987)

As the trend towards urbanization escalates, the United States is rapidly becoming a nation of non-farmers and suburban residents. Consequently, the conflicts between residents and wildlife species are increasing, while the interest in urban wildlife and backyard habitat is growing. These ' trends, coupled with changes in pesticide regulations, a shortage of trained professionals and relic legislation, create a complex and paradoxical situation for residents and professionals in the area of urban wildlife management. The future of wildlife in the urban environment will depend on our ability to convince and educate wildlife managers, citizens and legislators about the need for …

Closing Remarks, James E. Miller

Eastern Wildlife Damage Control Conference: 3rd (1987)

The need for professionalism in wildlife damage prevention and control is more important today than ever before. It will be even more important in the future as we are faced with increasing interaction between people and their interests which includes many different perceptions about wildlife. Wildlife professionals must change their philosophy regarding communication with the public about both the positive and negative impacts of wildlife. We can no longer afford the luxury, if indeed we ever could, of avoiding people and their perceptions about wildlife. We must provide scientific, biologically and ecologically sound information in a form which the public …

Control Of Ring-Billed Gull Colonies At Urban And Industrial Sites In Southern Ontario, Canada, H. Blokpoel, G.D. Tessier

Eastern Wildlife Damage Control Conference: 3rd (1987)

At eight urban or industrial sites in southern Ontario colonies of Ring-billed Gulls (Larus delawarensis) were controlled to ameliorate problems caused by the adults and their young. At the Nanticoke Generating Station on Lake Erie a growing colony was eliminated by collecting eggs and subsequent harassment of adults. One colony at the Stelco Yards in Hamilton Harbor was eliminated by installing a gull exclosure and collecting eggs from nests outside the exclosure and another was controlled by frequently destroying nests and eggs. At Toronto Island Airport an incipient colony was controlled by collecting eggs and harassing adults. At …

State/Federal/Private Cooperative Program Relationships In Wildlife Damage Control, Rene M. Bollengier Jr.

Eastern Wildlife Damage Control Conference: 3rd (1987)

On December 19, 1985, Congress transferred the Animal Damage Control (ADC).program from Fish and Wildlife Service (FWS), Department of the Interior, to Animal Plant Health Inspection Service (APHIS), United States Department of Agriculture (USDA). The transfer of personnel and equipment was officially completed on April 1, 1986. The transfer brought to USDA personnel with hundreds of years of collective animal damage control experience in agricultural and non-agricultural types of man/wildlife conflicts.

Frogs Captured In Green Bean Harvest:Analysis Of A Pest Problem, Donald F. Caccamise

Eastern Wildlife Damage Control Conference: 3rd (1987)

In southern New Jersey a new agricultural pest problem has seriously impacted production of green beans for plant processing. Newly acquired harvesters inadvertently capture frogs, which are difficult and expensive to remove from harvested beans. Goals of this project were to (1) define the biological properties of the pest problem, and (2) identify biologically sound and effective methods to manage the problem.

Fowler's toad (Bufo woodhousei fowleri) was the most numerous (82%) of 9 species sorted from harvested beans, and it was also the most common in field censuses (76%). Density estimates based on field censuses were higher …

Status Of The Coyote In The Northeastern United States, Robert E. Chambers

Eastern Wildlife Damage Control Conference: 3rd (1987)

This report represents a summary of information derived from responses to mail questionnaires from the state wildlife agencies in 16 northern states extending from Maine to Minnesota with minor modifications by the author where experience deemed it feasible.

Coyotes-historically present in prairie regions of Minnesota, Wisconsin, Illinois, Indiana and Michigan- have extended their range eastward to the Atlantic Ocean and are now present throughout most of the northeastern states with the exception of Delaware and the major metropolitan areas of Philadelphia and New York City. Of the eastern states only New York has suggested that their population may have arisen …

Temporal Use Patterns Of Wintering Starlings At A Southeastern Livestock Farm: Implications For Damage Control, J.F. Glahn, S.K. Timbrook, D.J. Twedt

Eastern Wildlife Damage Control Conference: 3rd (1987)

The farm use patterns of individually marked and transmitter-equipped starlings at a livestock farm in south-central Kentucky were studied each month during the principal damage period (December-February) of 1982-83 and 1984-85 following a pilot study in January and February of 1980. In addition to intensive observation at the farm, sightings of tagged starlings away from the farm were solicited from the public and mapped. For each year of data on individual starlings that used the farm at least once after marking, the expected frequencies of farm occurrence were calculated and compared to observed frequencies. In all 3 years, there was …

Fox Squirrels Cause Power Outages: An Urban Wildlife Problem, J.C. Hamilton, R. J. Johnson, R. M. Case, M. W. Riley, W. W. Stroup

Eastern Wildlife Damage Control Conference: 3rd (1987)

In urban areas, power outages are caused each year by fox squirrels (Sciurus niger) that use electrical power equipment as travel lanes, rest sites, or for other activities. When a squirrel crosses a live bare wire on a transformer, the result is a blown fuse and electrocution of the squirrel. Power company outage reports were examined to determine when and where squirrel-caused outages occurred. Sixteen field sites in Lincoln were selected for study. Eight sites encircled transformers with ≥4 squirrel-caused outages, 1980-1985, and eight were adjacent control sites with no such outages. Squirrel behavior in relation to power …

Wildlife Damage To Agriculture In Nebraska: A Preliminary Cost Assessment, R. J. Johnson, R. M. Timm

Eastern Wildlife Damage Control Conference: 3rd (1987)

We estimate the annual financial losses resulting from wildlife damage to major crops and livestock in Nebraska. For each wildlife species, the damage problem is presented along with a description of how the estimate was made. Field crop estimates include losses from Plains pocket gophers (Geomys bursarius), commensal rodents (Rattus norvegicus and Mus musculus), field rodents in grain fields (e.g. Peromyscus maniculatus, Dipodomys ordi, Spermophilus tridecemlineatus), house sparrows (Passer domesticus), blackbirds (e.g. Agelaius phoeniceus and Quiscalus quiscula), lagomorphs (Sylvilaqus floridanus, Lepus californicus, and L. townsendii), deer …

Taxonomic Status Of Wild Canids In The Southeastern United States, Michael L. Kennedy

Eastern Wildlife Damage Control Conference: 3rd (1987)

In the last 20 years (especially during the last decade), reports of coyote-like wild canids have increased steadily in the southeastern United States. These canids have apparently become well established in many parts of the Southeast. Taxonomically, the coyote-like animal could represent coyote (Canis latrans), red wolf (C. rufus), gray wolf (C. lupus), domestic dog (C. familaris), or hybrids of these taxa. There has been wide speculation (especially among the general public) in some areas as to the taxonomic status of wild canids. General references to wild "coy-dogs" (coyote x domestic dog …

A State-Administered User-Pay Program For Nuisance Wildlife Control, Dale W. May

Eastern Wildlife Damage Control Conference: 3rd (1987)

In recent years Connecticut, like many other northeastern states, has experienced dramatic suburban encroachment into woodland and farmland areas. The expansion of human population and the accompanying habitat alteration have resulted in a substantial increase in the frequency of wildlife/human conflicts. The Department of Environmental Protection's Wildlife Bureau, mandated to respond to the needs of the people as well as the wildlife of Connecticut, is the state agency given the responsibility of controlling nuisance wildlife problems. Although the Wildlife Bureau provides free technical assistance and educational material, in many cases landowners are either unwilling or unable to resolve nuisance wildlife …

Lethal Roost Toxicants For Control Of Starlings And Blackbirds, Denver L. Otis

Eastern Wildlife Damage Control Conference: 3rd (1987)

Roosting congregations of starlings (Sturnus vulgaris) and several blackbird species (Icteridae) cause several millions of dollars in losses to agricultural crops throughout the United States. In addition, they are responsible for a variety of nuisance problems, human and livestock diseases, and human safety hazards. Dozens of tools have been developed for alleviating these problems, some of which are nonlethal techniques aimed at either roost dispersal or site specific protection of the problem site. Lethal baiting techniques for use at staging areas or at the problem site have also been developed. However, the most controversial solution involves the use …

Extension's Perspective Of Federal, State And Private Animal Damage Control Programs, Gary J. San Julian

Eastern Wildlife Damage Control Conference: 3rd (1987)

Extension personnel are in a unique position to observe and to be involved in animal damage control (ADC) programs at the federal, state and private levels. In order to offer educational programs, we must interpret regulations and policies to provide a workable interface between ourselves, other agencies and the public. This is not an easy task in such a sensitive and emotional area.

The lack of uniformity in policies among federal agencies as well as the hazy lines of authority and responsibility for some species makes it hard to provide guidance for our clientele. The growing involvement of the public …

Bait Stations For Controlling Voles In Apple Orchards, Mark E. Tobin, Milo E. Richmond

Eastern Wildlife Damage Control Conference: 3rd (1987)

Bait stations made with polyvinylchloride (PVC) pipe were compared with hand-broadcast applications of rodenticides for achieving long-term control of pine and meadow vole populations (Microtus pinetorum and M. pennsylvanicus, respectively) in two apple orchards in the mid-Hudson Valley of New York. The stations were constructed of three pieces of 1.5-in diameter PVC tubing joined together in the shape of an inverted "T". Roofing shingles were placed over the entrances to some of the bait stations to encourage use by voles, while others were left uncovered. All stations were tied to trees, with no attempt to place them near …

Preliminary Testing Of A Selenium-Based Systemic Deer Browse Repellent, T.R. Angradi, W.M. Tzilkowski

Eastern Wildlife Damage Control Conference: 3rd (1987)

Silviculturists use a variety of techniques, including repellents, to reduce browse damage by white-tailed deer (Odocoileus virginianus) to valuable eastern hardwood seedlings. Systemic selenium, sodium selenite, was evaluated with captive white-tailed deer for its repellency in white ash (Fraxinus americana) and black cherry (Prunus serotina) seedlings. Selenium had no effect in reducing browsing of black cherry. However, there was a reduction (p<0.05) in the white ash browsing level.
