Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A. R. Stickley Jr., R. J. Weeks
Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A. R. Stickley Jr., R. J. Weeks
Wildlife Damage Management Conference
Histoplasrnosis is a common and sometimes serious fungal disease that primarily affects the lungs, but can also involve other parts of the human body. The disease is characterized by 3 major forms: acute pulmonary, chronic cavitary, and disseminated histoplasmosis.Two fungicides are effective in treatment of the disease, but serious side effects often result. The occurrence of the fungus, Histoplasma capsulatum, is associated with large quantities of bird and bat excreta that have come in contact with soil. Roost sites must generally be occupied by birds for at least 3 years before soil conditions are conducive to its growth. Once established, …
Dispersing Blackbird-Starling Roosts With Helium-Filled Balloons, Donald F. Mott
Dispersing Blackbird-Starling Roosts With Helium-Filled Balloons, Donald F. Mott
Wildlife Damage Management Conference
Large (120 cm diameter) helium-filled balloons (2-10 per ha of roost) tethered about 8 m above the vegetation were effective in dispersing blackbirds and starlings from roosting sites. Bird population estimates before, during, and after balloon exposure showed that the balloons frightened the birds and caused most of them to abandon the roost. Roosting bird numbers at each of 5 test roost sites (0.3 to 1.7 ha) were reduced an average of 82% (min-max 47-100%) during 3 to 4 evenings of balloon exposure. Winds >16 km/h during the study made it difficult to keep the balloons aloft and not entangled …

In 1971 the United Nations Educational, Scientific, and Cultural Organization (UNESCO) created the Man and the Biosphere (MAB) Program for the purpose of promoting rational use of the earth's resources. Formal involvement by the U.S. began in 1974. By 1976, 28 biosphere reserves had been selected in the U.S., including Big Bend National Park (BBNP) (Fig. 1). The purpose of this 2-volume report was to provide an interdisciplinary reference volume of literature citations for BBNP and the surrounding Chihuahuan Desert, and to provide a synopsis of research completed at BBNP.

Comparison Of Bootstrap And Jacknife Statistical Procedures, Amanuel Gobena
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This report compares the bootstrapping to jacknifing statistical procedures in terms in bias, confidence interval and estimation of median. Related literature have been reviewed. A bootstrap allows a researcher to get an approximation to the distribution of possibly complicated statistical summaries. It is based on random sampling with replacement from experimental units. Jacknife has also been in operation prior to bootstrapping statistical procedure. The jacknife divides the data into subgroups and obtains partial estimates of these subgroups by omitting one subgroup at a time. When both of these statistical resampling procedures are compared the bootstrap has less bias, more accurate …
