Predators On Red-Winged Blackbird Nests In Eastern North Dakota, Richard S. Sawin, Mark W. Lutman, George M. Linz, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

Predation has consistently been identified as the most common cause of nest failure for Red-winged Blackbirds (Agelaius phoeniceus). During May and June, 2000 and 2001, we used infrared-triggered camera systems to identify potential nest predators on artificially relocated Red-winged Blackbird nests in eastern North Dakota. For some of the species observed, these observations represent the first documentation of predation on Red-winged Blackbird nests in the northern Great Plains.

Fisheries Research Contract Report No. 2 - Towards An Assessment Of Natural And Human Use Impacts On The Marine Environment Of The Abrolhos Islands (Phase 1 : Data Consolidation And Scoping - Final Report For Frdc Project 2000/1 66), C. F. Chubb, K. Nardi

Fisheries Research Contract Reports

This project has drawn together existing research data relating to natural and human impacts on the Abrolhos Islands marine habitats. It has surveyed current uses of these habitats and placed anthropogenic impacts within the context of natural perturbations. Through public forum presentation and debate, this work has allowed real issues, not perceptions, to surface and be addressed properly. This was achieved by defining a strategic programme of research through a scientific workshop process involving all community stakeholders. A two volume Fisheries Research Report (WA) summarizes current knowledge and details the workshop proceedings and strategic research plan.

Population Monitoring In Support Of A Rabies Vaccination Program For Skunks In Arizona, Richard M. Engeman, Kevin L. Christensen, Michael J. Pipas, David L. Bergman

United States Department of Agriculture Wildlife Services: Staff Publications

Three population monitoring methods were evaluated in support of a trap/vaccinate/release program for controlling a bat variant of rabies virus in skunks (Mephitis mephitis) in Flagstaff, Arizona (USA). Skunks were the primary species targeted for population monitoring during the program, but feral cats were also monitored as they represented an abundant secondary vector species capable of rabies transmission. Skunks were vaccinated and released, except for a subset tested for rabies. All captured cats were placed in the local animal shelter. Spotlight surveys essentially did not detect skunks, and were not able to detect reductions in the cat population. …

Terrestrial Natural Communities Of Nebraska (Version Iii - June 30, 2005), Gerry Steinauer, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

For more than a decade, The Nature Conservancy (TNC) and state natural heritage programs, including the Nebraska Natural Heritage Program (NNHP), have used a “coarse filter/fine filter” approach to preserving biological diversity (The Nature Conservancy, 1994). This approach involves identification and protection of natural communities (coarse filter) as well as rare species (fine filter). Identifying and protecting representative examples of natural communities ensures conservation of most species, biotic interactions and ecological processes. Those species that “fall through” the community filters are generally the rare species. Identification and protection of viable occurrences of rare species serves as the fine filter for …

4,4'-Dinitrocarbanilide (Dnc) Concentrations In Egg Shells As A Predictor Of Nicarbazin Consumption And Dnc Dose In Goose Eggs, Randal S. Stahl, Kurt C. Vercauteren, Dennis Kohler, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

Nicarbazin is being investigated as an infertility agent for the control of non-migratory Canada geese (Branta canadensis L) populations. Nicarbazin is presently registered for use as a coccidiostat for poultry. Geese fed sufficient quantities of nicarbazin will lay non-viable eggs. We established nicarbazin consumption by measuring the concentration of a component of the formulation, 4,4’-dinitrocarbanilide (DNC) in the egg contents (yolk, albumin) in non-viable eggs. To estimate the nicarbazin consumption of birds that laid viable eggs (eggs that hatched or contained an embryo), a high-performance liquid chromatography method was developed to measure the concentration of DNC in egg …

Bioassessment Of The West Fork Of The White River, Northwest Arkansas, Arthur V. Brown, Andrea J. Radwell, Robin A. Reese

Arkansas Water Resources Center Technical Reports

The West Fork-White River has been and continues to be an important water resource for northwest Arkansas. It is used recreationally for fishing and swimming, agriculturally as a source of water for livestock and irrigation of crops, it is mined for gravel, used as a receiving stream for municipal wastewater effluent, and contributes to Beaver Lake which provides water for treatment and distribution to most of northwest Arkansas. While these uses have benefited a large segment of the Arkansas population, they have also contributed to the decline in environmental quality of the river. To facilitate the development of appropriate management …

Effects Of Lining Cooling Tower Interior Walls On Controlling The Growth Of Legionella Pneumophila, Kamal Rafiq Saeed Jaroor

Theses

The presence of Legionella pneumophila in cooling tower waters is a serious health hazard. If the contaminated mist from the cooling tower is inhaled, Legionnaires' disease could be contracted. Of the 2.4 million cases of pneumonia that occur each year in the United States, an estimated 8,000 to 18,000 are actually cases of Legionnaires' disease. Several factors have been suggested in the literature that enhance the high bacterial count in cooling towers including: temperature, pH, water stagnation, and presence of algae and protozoa.

On few occasions, water samples from the cooling tower at Dubai Hospital tested positive for Legionella pneumophila …

Cool Temperatures Elicit Reproduction In A Biologically Invasive Predator, The Brown Treesnake (Boiga Irregularis), Tom Mathies, Lowell A. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Two different temperature regimes for eliciting reproduction in male and females of the Guam form of the brown treesnake were investigated. Males and females maintained at 24°C followed by a 60-day cool period at 19°C exhibited substantial reproductive activity, and the females that produced clutches did so during a brief period after return to 24°C. In contrast, individuals maintained at 28°C followed by an identical 19°C cooling period exhibited relatively little reproductive activity, and although some females became vitellogenic, none produced eggs. Reproductive activity was virtually absent in all individuals in both groups 7 months after the end of the …

Longevity Of A Woodhouse's Toad, Richard M. Engeman, Melvin A. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

We follow up a report on a male Woodhouse's toad (Bufo woodhousii) that had been observed since 1978 (Engeman RM, Engeman EM. 1996. Longevity of Woodhouse's toad in Colorado. Northwestern Naturalist 77:23). The toad had found its way into, and remained in, a basement window-well of a brick home in an unincorporated western suburb of Denver, Colorado. This property has recently changed hands, and access for future monitoring of the toad's survival is uncertain. Thus, we report its longevity as of 2002.

Immobilization Of Fission Iodine By Reaction With A Fullerene Containing Carbon Compound And Insoluble Natural Organic Matrix, Spencer M. Steinberg
