Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell

Agriculture reports

These pasture condition guides are relevant to about 192 000 square kilometres of the Pilbara region of Western Australia. The rangeland of the Pilbara can be separated into 12 very broad pasture types. The ‘pasture type’ is not strictly a botanical classification because, in determining such a class of pastoral lands, the perennial plant species that contribute to stock production have an over-riding importance. Even so, each pasture type represents a broad group of similar vegetation associations or ‘site types’ which will have similar management requirements for pastoralism. The aim of this publication is to provide pastoralists with descriptions and …

The Tide Is High For The Boston Beaches, Marissa Glowac

New England Journal of Public Policy

In 1993, Massachusetts Governor William Weld and Boston Mayor Thomas Menino approved the “Back to the Beaches” project, a seven-year, $30.5 million public project to restore nineteen Boston Harbor beaches. Today, these sites have new, cleaner sand, improved access, and new amenities and facilities now ready to offer additional opportunities for recreation. People are coming back to the Boston Harbor beaches in numbers significantly higher than a decade ago. This study concludes that the implementation and success of the “Back to the Beaches” project can be attributed to several factors — an increased public awareness of the value of open …

Prairie Dogs And The Prairie Ecosystem, Scott E. Hygnstrom, Dallas R. Virchow

School of Natural Resources: Faculty Publications

Prairie dogs play an important role in the prairie ecosystem by creating unique patches of habitat in the expansive prairies of the American West. Their daily activities change the physical characteristics of the community, which leads to increased plant and animal diversity. Prairie dogs are a source of food for several predators, and their burrows provide homes for a variety of species, including the burrowing owl and endangered black-footed ferret. They also provide recreational opportunities for nature observers, photographers, and the sporting public. The presence of large, healthy prairie dog towns, however, is not always compatible with agriculture and other …

Development Of Membrane Extraction Techniques For Water Quality Analysis, Dawen Kou

Dissertations

This research involved the development of membrane-based analytical techniques as applied to various aspects of water quality analysis. Gas injection membrane extraction was developed for fast on-line analysis of volatile organic compounds in water. Gas injection of aqueous samples increased the speed of membrane extraction. The aqueous boundary layer effects encountered during water elution was reduced. Axial mixing of the sample with a gaseous eluent was minimal, and this eliminated the tailing in the permeation profiles. The overall effect was significantly faster penneation. The overall diffusion coefficient during gas injection was found to be seven times the value during aqueous …

The Ideal Lead Time For Tornado Warnings - A Look From The Customer’S Perspective, Rick Ewald, Jared L. Guyer

United States Department of Commerce: Staff Publications

Improving the amount of advanced warning time (lead time) for tornado warnings is one of the goals spelled out in the National Weather Service (NWS) Vision 2005 Strategic Plan (1999). Since the beginning of the NWS modernization effort, tornado warning lead times have increased from four to ten minutes, with the goal of 15 mi nutes set for 2005. In concert with increasing lead times, the NWS also has goals in place for increasing the probability of detection (POD) while decreasing the false alarm rate (FAR).
Accomplishing these goals will be no easy task. Rothfusz (2000) noted that forecasters may …

Availability Of Organochlorides And Accumulation In Populations Of Tadarida Brasiliensis (Free-Tailed Bat) And Eptesicus Fuscus (Big Brown Bat), Michelle Lee Smith

Theses and Dissertations

Organochlorides were historically effective in controlling a wide range of pests. However, organochlorides have proved to present many problems to the health and welfare of other organisms. Due to these problems, especially declines in wildlife populations, organochlorides were restricted in the 1970's and a majority of them were banned in the mid to late 1980's. The effects of organochlorides on bats such as Tadarida brasiliensis and Eptesicus fuscus have been intensively studied. The effects can range from problems with reproduction to mortality. My analysis of populations of T. brasiliensis and E. fuscus showed that organochlorides are still present in the …

A Regional Gis-Based Analysis Of Elk Habitat Suitability In Northwestern Nebraska, Justin W. Fischer

School of Natural Resources: Dissertations, Theses, and Student Research

The need to accurately assess the use and suitability of elk (Cervus elaphus spp.) habitat at regional scales will continue to increase as human development encroaches into what was once optimum elk habitat. The objectives of this research were to calculate the relative proportions of habitat use by elk in the Pine Ridge region of Northwestern Nebraska from a set of radio-collared elk locations and generate a habitat suitability model. Habitat variables (Iandcover type, aspect, slope, distance to a road, road density, and distance from the ponderosa pine edge) were measured for each elk location (n = 5,787 dating …

Poly(Methyl Methacrylate) Synthetic Grit Formulations Sustain The Delivery Of Nicarbazin, A Contraceptive Agent, In Pest Waterfowl, Jerome C. Hurley, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

Sixty-three mallards were fed one of ten poly(methyl methacrylate) based synthetic grit formulations containing varying concentrations of a proposed wildlife contraceptive (nicarbazin), plasticizer (acetyl tributylcitrate) and/or cross-linking agent (1,4-butanediol diacrylate). Release characteristics of the contraceptive agent were monitored for the purpose of developing a contraceptive formulation for control of pest waterfowl in urban settings. The addition of plasticizer increased the erosion rate (t_1/2=0.97-2.85 days), cross-linking the polymer matrix slightly decreased the erosion rate (t_1/2=4.45-5.05 days) and increasing the concentration of the contraceptive agent increased the erosion rate (t_1/2= 3 . 3 …

United States Department of Agriculture Wildlife Services: Staff Publications

We examined if Valley pocket gophers (Thomomys bottae) exhibited a seasonal preference for consuming steamed-rolled oat (SRO) groat bait treated with 1.6% Dupont oil blue A (fat-marking dye). Field tests were conducted in California alfalfa fields during winter, summer, and fall, and in walnut orchards during winter and summer. Five treatment units (TUs) were established each with 60 burrows for each season and habitat studied during 1997–1999. SRO groat marker bait (4 g) was placed inside each active burrow. All bait sites were re-opened about 96 h later and examined for the presence (all or some) or absence …

Safe Efficacy Of Three Strychnine Alkaloid Bait Concentrations For Hand-Baiting Control Of Plains Pocket Gophers, Craig A. Ramey, George H. Matschke, Paul L. Hegdal, Geraldine R. Mccann, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

In November 1990, field efficacy studies using milo baits formulated with 0.35%, 0.75%, or 1.30% strychnine alkaloid were compared to a placebo (0.0% strychnine) for controlling plains pocket gophers (Geomys bursarius) near Pleasanton, Texas. These data were required by the US Environmental Protection Agency (EPA) as partial fulfillment for the maintenance of the rodenticide registrations of the US Department of Agriculture. Each of four treatment units (TUs) within a block (2) was randomly assigned one of the four baits. Within each TU, 15 gophers were captured (balanced roughly for gender) and instrumented with radio transmitters. Following a pretreatment …

Sustained Evaluation Of The Effectiveness Of Detector Dogs For Locating Brown Tree Snakes In Cargo Outbound From Guam, Richard M. Engeman, Daniel S. Vice, Darryl York, Kenneth S. Gruver

United States Department of Agriculture Wildlife Services: Staff Publications

The accidental introduction of the brown tree snake (Boiga irregularis) to Guam has resulted in the extirpation of most of the island's native terrestrial vertebrates, has created a health hazard to infants and children, and has resulted in economic losses. The high brown tree snake population densities on Guam, the species' adaptations for successful dispersal, and Guam's position as a focal point for commercial and military cargo shipments have created a high level of concern that brown tree snakes could spread from Guam to colonize other vulnerable locations. Cargo inspections using teams of handlers and their detector dogs …
