Diatoms In The Gills Of The Commercial White Shrimp, Robin M. Overstreet, Susan Safford

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A white shrimp from Galveston, Texas, is the first reported case of a crustacean internally infected by a diatom. Even though more than one species occurred in debris on and between gill filaments, only individuals of Amphora sp. occurred within gills. To determine if a related diatom would easily reproduce within the shrimp and cause. a host response similar to that observed, we injected cultured specimens of A. coffaeformis into white shrimp. Under the experimental conditions, individuals of that species did not divide, but they elicited an extensive melanistic host-response.

The Status Of Prairie Dogs In The Great Plains, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

The data used in this report was acquired during an investigation conducted for the Development Planning and Research Associates Incorporated located here in Manhattan, Kansas: This is a private consulting firm. Their permission to use this information is greatly appreciated. There are four species of prairie dogs in the United States. These are the black-tailed prairie dog (Cynomys ludovicianus), white-tailed prairie dog (Cynomys leucurus), Utah prairie dog (Cynomys parvidens) and Gunnison's prairie dog (Cynomys gunnisoni) (Jones et al, 1975).

Extension Program Planning For Predator Damage Control, Dale A. Wade

Great Plains Wildlife Damage Control Workshop Proceedings

Program planning for reduction of predator damage through the Extension approach normally involves producers, the county Extension agent and the Extension specialist in animal damage control. Please note that I will use the term "animal damage" rather than "wildlife damage", since free-ranging and feral dogs are frequently responsible for predator-caused losses and reducing these losses is equally as important as limiting losses to wild species.

How Wildlife Damge Control Personnel Can Cope With The Gas Shortage And Reduced Budgets, Yet Still Meet The Needs Of The Public, Volney W. Howard Jr.

Great Plains Wildlife Damage Control Workshop Proceedings

As I see the situation, we are really addressing a two-sided issue -- one involves actual field personnel, such as Animal Damage Control (ADC), and the other contains those involved in extension. Some potential solutions which may be beneficial for one group may not be applicable to the problems encountered by the other. ADC Personnel. The field personnel are faced with increased fuel costs and static or decreased travel budgets. In addition, there is rumor of a 10 to 15% mandatory decrease in gasoline consumption on a per-month-basis by ADC employees in New Mexico. I assume that ADC personnel in …

Extension Education Within The U.S. Fish And Wildlife Service, Dan Stiles

Rangeland Management Problems Associated With Wildlife From A Rangeman's Viewpoint, Paul D. Ohlenbusch

Great Plains Wildlife Damage Control Workshop Proceedings

Rangeland is the largest renewable natural resource of the Great Plains states. It supplies forage for the livestock industry (together with tame pasture), habitat for wildlife, water for man and animals, beauty and pleasure for everyone and an economic base for many rural communities. In short, it is many things to many people.

Ground Squirrels In The Great Plains, Bennett A. Brown

Great Plains Wildlife Damage Control Workshop Proceedings

There are 22 recognized species of ground squirrels in North America (Jones et al. 1975). All belong to the genera Spermophilus or Ammospermophilus. Some species contain as many as 14 subspecies, or races. In many cases, these subspecies are distinguished not only by morphological or distributional characters, but by behavioral differences and varying ecological strategies, as well. These latter frequently impact on the efficacy of various control methods.

Nineteenth-Century Urbanization Patterns In The United States, Roger Riefler

College of Business: Faculty Publications

By viewing urban areas in the northeast quadrant of the United States as a system of cities, this paper attempts to isolate the common factors precipitating the overall pattern of urbanization in the nineteenth century. For the antebellum period commercial activity, both interregional and especially intraregional trade, appears to be the driving force generating urbanization. During the post-bellum period manufacturing comes to the fore as the prime factor allowing cities to grow at a rate exceeding that of their hinterland.

Pigeon Associated People Diseases, Walter Weber

Bird Control Seminars Proceedings

Feral pigeons (Columbia livia) are not harmless birds. Many potential infections of humans silently exist in pigeons which are not apparent. They have the potential for transmission of over 30 diseases to humans plus another ten to domestic animals. Environmental pollution from pigeon droppings is quite evident. Air pollution involves more than noxious gases from automobile exhausts and belching smokestacks. One serious air pollutant is air-borne fungi, which are agents for infectious diseases. There is much information written about the problem, but it remains primarily in the professional journals and technical references, neatly stacked away on library shelves. …

New Developments In Bird Resistant Sorghums, Roger W. Bullard

Bird Control Seminars Proceedings

In recent years there has been a major shift of emphasis from lethal to nonlethal methods of controlling bird damage to agricultural crops. In addition to being unpopular, killing large number of birds has generally been ineffective because of rapid recovery of populations. Consequently, most of the methods that are now being investigated emphasize crop protection. Since sorghums are especially vulnerable to bird damage, considerable effort has been expended in the past 20 years to develop varieties that have morphological or chemical characteristics which are resistant to bird damage (Harris, 1969; Tipton et al., 1970; McMillian et al., 1972). Some …

Review Of Avian Mortality Due To Collisions With Manmade Structures, Michael L. Avery

Bird Control Seminars Proceedings

Birds have undoubtedly been colliding with manmade structures ever since humans started building things skyward. The earliest documented instances of collision mortali- ty in this country are from the late 1800's (Coues 1876, Merriam 1885) and the problems continue unabated today. The total avian mortality due to collisions with manmade obstacles is probably greater every year as buildings, towers, chimneys, overhead power lines, and other structures are erected in ever-increasing numbers. Weir (1976) provides an excellent review of bird migration, weather, and collision mortality associated with various types of structures.
The biological significance of collision mortality to any species is …

Bird Control And Endangered Species, Denis S. Case

Bird Control Seminars Proceedings

The potential exists for a conflict to occur between endangered species and almost any type of human endeavor. Detrimental effects on endangered species are possible even as a result of efforts to benefit other endangered species. The types of possible conflicts range from potential problems that are easily solved in early planning processes to major brouhahas involving nearly every conceivable agency and party. Relative to bird control, it is important to understand the true magnitude of the situa- tion and to develop a factual perspective. According to Ziswiler (1967), 169 species and subspecies of birds have become extinct since the …

Behavioural And Physiological Problems Associated With The Development Of Curb, Rufus J. Stone

Bird Control Seminars Proceedings

CURB is a harmless chemical repellent formulated and prepared to control avian and mammalian behavior which may result in losses of cultivated crops at all stages of growth, of food in storage, and also in behavior which may endanger health (e.g. dogs fouling) or life (e.g. birds on runways at airports). It is a fine powder, which may be wet- table for spraying when mixed with water; or it may be prepared for dry application. It is synergised aluminum ammonium sulfate. Its LD50 is greater than 5 gr/kg; it has passed the U.S.A. and French skin and eye mucosa tests …

Cardiac And Operant Behavior Response Of Starlings (Sturnus Vulgaris) To Distress And Alarm Sounds, R. Daniel Thompson, Brad E. Johns, C. Val Grant

Bird Control Seminars Proceedings

A variety of auditory stimuli have been used for many years as a means of repelling nuisance birds from problem areas (Boudreau, 1968; Bremond et al., 1968; Frings and Jumber, 1954; Langowski et al., 1969; Nelson and Seubert 1966; Pearson and Corner, 1967; Thompson et al., 1966, 1968a, b). This approach to alleviating bird problems is ap- pealing because wild birds are considered very sensitive to sound stimuli of biological origin, and such stimuli are harmless to both target and nontarget species. The harmless aspect is an important advantage in dealing with wildlife related problems because of the increased public …

Avian Hosts Of St. Louis Encephalitis Virus , Robert G. Mclean, Thomas W. Scott

Bird Control Seminars Proceedings

St. Louis encephalitis (SLE) virus normally infects birds and is transmitted between birds by mosquito vectors. Thus it is an arthropod-borne virus (arbovirus). SLE virus is found throughout the Americas, and human disease has been reported from the nor- thern part of the hemisphere. Human epidemics have been reported only from northern Mexico (Gonzalez Cortes, et al. 1975), the United States, and southern Canada (CDC 1977). Other viruses closely related to SLE (dengue, yellow fever, and Rocio viruses) cause epidemics in Central and South America. In the United States, SLE is the most important mosquito-borne disease of humans in terms …

Research In Support Of The College Teacher, B. Claude Mathis

POD Quarterly: The Journal of the Professional and Organizational Development Network in Higher Education

College teaching has traditionally been regarded by a majority of its practitioners as a profession having much in common with the ministry. Those who commit their lives to the front lines of higher education often do so with a dedication which suggests having been called to the task by whatever teleology their disciplines embrace. Teaching in this context becomes a mystical skill which, in its existential unfoldings, loses its artful essence if studied in the objective light of empirical analysis. Those who attempt to study teaching and learning do so at the risk of creating a network of knowledge about …

High School Students' Images Of Geography: An Exploratory Analysis, Raymond Hubbard, Robert Stoddard

Geography Program: Faculty Publications

Almost since its introduction into American high schools and colleges, geography has been plagued with the problem of justifying its existence as a bona fide academic discipline. This identity problem has been attributed to a variety of circumstances and conditions, including the common explanation that geography is a virtually unbounded discipline. For many individuals this unduly amorphous characteristic is particularly burdensome when attempts are made to define the subject matter of geography. This, in turn, hampers the presentation of a clear and distinct image of the discipline to nongeographers. Closely related to the problem of geography's diverse content and delineation …
