Coccidiosis Of Sand Hill Cranes (Grus Canadensis) Wintering In New Mexico, Brent B. Parker, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The feces of 212 Sandhill cranes (Grus canadensis) collected in central New Mexico from October 1982 to January 1983 and from October 1983 to January 1984 were examined to determine the prevalence of coccidial oocysts. One hundred forty-five granulomatous nodules from the viscera of 64 cranes and samples of lung, small intestine, and large intestine from 58 birds were examined by light and transmission electron microscopy for the presence of intestinal or extraintestinal coccidiosis. Of the 212 fecal samples, 160 (75%) were positive for oocysts of Eimeria, including E. gruis in 139 (66%) and E. reichenowi in …

Biography Of Glenn L. Hoffman, R. M. Overstreet, F. P. Meyer

United States Fish and Wildlife Service: Publications

In the fictional West of the United States, a masked man known only as the Lone Ranger rode into the lives of troubled individuals on his white stallion, Silver, and, with the aid of his trustworthy Indian sidekick, Tonto, and a six-shooter filled with silver bullets, solved the people's problems and protected them from villains. When the Lone Ranger finished his deed, he rode away and a person who had received help always asked someone nearby 'Who was that masked man, anyway?'

Genotype And Genotype X Environment Interaction Effects For Forage Yield And Quality Of Intermediate Wheatgrass, Kenneth P. Vogel, P. E. Reece, J. F. S. Lamb

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Intermediate wheatgrass [Thinopyrum intermedia (Host) Barkworth and D.R. Dewey] is grown over a vast geographical area in North America, but information on the genetic variability for agronomic traits and the stability of these traits over environments is limited. Genotype and genotype X environment interaction effects for forage yield and quality of intermediate wheatgrass were studied using 36 strains (plant introductions, experimental strains, and a released cultivar). They were grown in two central Great Plains environments, Lincoln and Alliance, NE, that differ markedly in climate. Forage yield and forage quality, measured by in vitro dry matter digestibility (IVDMD) and percent …

Renovation Of Seeded Warm-Season Pastures With Atrazine, T. O. Dill, S. S. Waller, Kenneth P. Vogel, R. N. Gates, W. W. Stroup

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Numerous warm-season pastures have been established in the last 30 years in the central Great Plains. Some of these pastures are old enough to verify that they can be abused by overgrazing as easily as native tallgrass prairies. Overgrazed warm-season pastures are invaded and dominated by cool-season grasses such as smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.), which diminishes the pasture productivity during the hot summer months. Since established warm-season grasses have greater tolerance to the herbicide atrazine than cool-season grasses, the effectiveness of atrazine applications in renovating invaded warm-season pastures was evaluated. A …

Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch

Great Plains Wildlife Damage Control Workshop Proceedings

The Giardia lamblia (Lambl) protozoan is not a recently discovered parasite. It was. in fact, one of the first organisms viewed and described by Antony van Leeuwenhoek (1681) as he designed the first usable microscope. Leeuwenhoek found this organism in a sample of his own diarrhetic stool and thus he constitutes the first confirmed case of human giardiasis. His finding represents proof of glardiasis’ close association with man for many years. Leeuwenhoek’s discovery of the giardial trophozoite was not elaborated on for some 178 years, however, as it was not until 1859 that Wilhelm D. Lambl systematically described the organism …

The Use Of Fixed Wing Aircraft In Predator Control, Larry D. Vetterman

Great Plains Wildlife Damage Control Workshop Proceedings

Aerial hunting was first used in a professional predator control program in 1942. The most popular aircraft used by animal damage control agencies is the Piper PA-18. Proper training of flight crews is of utmost importance for a successful aerial operation. Fixed wing hunting is restricted to relatively open areas and flat terrain. Aerial hunting is an excellent control method where livestock losses are severe and immediate control is needed.

Current Status And Potential Registrations Of Compound 1080 And Strychnine For Rodent Control, Lyle A. Crosby

Great Plains Wildlife Damage Control Workshop Proceedings

On December 1, 1976, the Environmental Protection Agency applied Section 6 of the Federal Insecticide. Fungicide, and Rodenticide Act, "Administrative Review", in determining that the use of products containing strychnine, for above ground application to control several rodent species, met specific cancellation criteria outlined in 40 CFR 162.11. Position Document 4 (the final Agency decision), published on September 30, 1983, proposed to cancel registrations of strychnine products for above ground use to control prairie dogs and required label modification for confined use on ground squirrels. The final decision was challenged by several parties who requested a formal hearing which was …

Preliminary Studies On The Feasibility Of Urban Rabies Control, Richard C. Rosatte

Great Plains Wildlife Damage Control Workshop Proceedings

A preliminary investigation was initiated in 1984 to determine the feasibility of an urban rabies control strategy which involved capturing, vaccinating and releasing skunks and raccoons in metropolitan Toronto, Ontario. Results indicate urban skunks and raccoons are utilizing extremely small home ranges and their movements are not extensive. Trapping data suggested a large proportion of the population of skunks and raccoons in the study area were captured during the first 4 nights of trapping. Capture data also indicated the presence of new animals in the study areas between trapping periods. The 3 study areas, which differed in human land-use classification, …

Preliminary Field Evaluation Of A New Formulation Of Rozol ( Chlorophacinone ) Bait Against Pocket Gophers In Colorado, John A. Baroch, Richard M. Poche

Mountain pocket gophers (Thomomy's talpoides) and plains pocket gophers (Geomys bursarius) are a problem to rangelands in Colorado. A new chlorophacinone (50 ppm) pelleted bait was applied to active burrow systems by hand baiting. Efficacy on the Geomys plot was 100%, while 94.73% of the Thomomys were controlled with the product.

Aggressive Behavior Of Mississippi Kites In Suburban Areas, Berkeley R. Peterson, Charles S. Brown

Great Plains Wildlife Damage Control Workshop Proceedings

The Mississippi Kite is a small diurnal bird of prey which nests throughout the southern Great Plains Its aggressive behavior during nesting has created problems for residents in suburban areas. The removal of the nest and relocation of the eggs and young will end the attacks by the parent birds. The eggs are incubated and the resulting young, as well as other young removed from problem nests, are then placed in foster nests in more remote areas. Preliminary results indicated this will be a very successful way of dealing with the young of problem kites and is an effective way …

Wildlife In Texas: Marketing Potential And The Significance Of Wildlife Damage, Milo J. Shult

The Effect Of Dietary Protein And Feed Size On The Assimilation Efficiency Of Starlings And Blackbirds, Daniel J. Twedt

Great Plains Wildlife Damage Control Workshop Proceedings

Starlings (Sturnus vulgarisl were fed 3 feed sizes and 3 protein levels of swine feeds to determine metabolizable energy and assimilation efficiency. Metabolizable energy (12 kcal/g of diet consumed) and assimilation efficiency (3296 of gross energy intake) were independent of feed size. A 46% crude protein diet was 5196 assimilated and yielded more energy per gram of diet consumed than a 2196 crude protein diet which was only 35% assimilated. Starlings failed to maintain their body weight on a cracked corn diet containing 14% crude protein. Feeding behaviors of starlings due to their assimilation efficiencies are discussed and contrasted with …

Alligator Nuisance Control Program In Texas: Problem And Process, Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in 1983 in Texas (Bowman 1983). Similarity of appearance classification acknowledges the biological security of the Texas alligator population and the need for specific harvest controls to ensure that the conservation of similar appearing species is not compromised. As alligator populations recovered, nuisance complaints directed to the Texas Parks and Wildlife Department (T'PWD) accelerated as well. Complaints now number several hundred annually and …

Deer Damage Prevention Efforts In Pennsylvania, Jack M. Payee, William L. Palmer

Great Plains Wildlife Damage Control Workshop Proceedings

Research at the Pennsylvania State University was directed towards finding effective repellents to control damage caused by white-tailed deer (Odocoileus virginianus) and to develop a low-cost alternative to the traditional 2.4 m woven wire barrier fence, considered to be deer-proof, but too expensive for mgt agricultural uses. Fourteen repellents were screened and 9 were found to be more effective than the others. These 9 repellents were further investigated under semi-field conditions and only 1 repellent was found to be consistent in reducing deer feeding. A vertical electric deer fence was effective in excluding deer at field sites containing alfalfa, small …

Wildlife Diseases And Human Health, Keith A. Clark

Great Plains Wildlife Damage Control Workshop Proceedings

Zoonoses (singular, zoonosis) are diseases transmissible from animals to man. There are over 200 such diseases; many are harbored by wildlife reservoirs. A reservoir may be defined as a source which maintains the presence of a disease in an ecosystem. Wildlife-associated "zoonoses found in Texas include rabies, plague, tularemia, Rocky Mountain spotted fever, Lyme disease, leptospirosis, relapsing fever, typhus, and leprosy. The mission of the Zoonosis Control Division of the Texas Department of Health is to protect the health of Texas citizens against zoonoses. Surveillance programs for various diseases are an integral part of the overall control programs, which include …

The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley

Great Plains Wildlife Damage Control Workshop Proceedings

In the early 1900's organized predator control was initiated to remove coyotes and wolves from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920's, many of the inner Edwards Plateau counties were considered to be practically free of coyotes (Canis latrans) and wolves (Canis lupus, Canis rufus). The 1950's found coyotes and wolves extirpated from most of the Edwards Plateau. After a coyote population erruption in the late 1950's, coyotes began to re-establish themselves on the periphery of the Plateau. This encroachment process continued throughout …

Black-Tailed Prairie Dog Management On The Northern Great Plains New Challenges And Opportunities, Greg L. Schenbeck

Great Plains Wildlife Damage Control Workshop Proceedings

Implications of new information and several recent developments to the management of black-tailed prairie dogs (cynomys ludovicianusl on the northern plains are discussed. Of primary importance is the need to conduct management programs that are as cost-effective as possible and responsive to the concerns of private land interests. Research findings indicate that cost-effectiveness can be improved by combining rodenticide use with changes in livestock grazing practices to reduce habitat suitability for prairie dogs. Other research suggests that reduced concentrations of Compound 1080 for prairie dog control warrants continued scientific evaluation. If reduced concentrations of 1080 could be used effectively and …

Beaver Problems Associated Wtth Conservation Activities, Ed M. Schwille

Great Plains Wildlife Damage Control Workshop Proceedings

As far back as 1935, the U.S. Department of Agriculture, Soil Conservation Service (SCS) began providing technical assistance to private landowners to build ponds and small lakes. To date in Texas, over 500,000 structures of this type have been built. During the 1940's, the SCS started construction of Watershed Protection and Flood Control Impoundments in Texas. These flood prevention structures number about 1,900. Other programs have brought about construction of over 16,000 grade stabilization structures (GSS) for erosion control. Numerous ponds and lakes have been built without any help from the SCS over the years. All of these impoundments store …
