Reading The Rangeland: A Guide To The Arid Shrublands Of Western Australia, Don Burnside, Alec Holm, Alan Payne, Georgina Wilson

All other publications

Managing the rangelands is complex. Soils and vegetation can vary considerably over short distances in distinct or subtle ways. Separating climatic from management influences on the condition of the land has always been difficult. Whether we live on a sheep station, in a country town, in an Aboriginal community, a mining camp, or even if we only visit the Australian outback, it is vital that we understand and appreciate the unique character and management requirements of the rangelands. Learning to ‘read the rangeland’ has been a slow process, involving the knowledge and skills of pastoralists, Aboriginal people and scientists. This …

Alternative Methods Of Predator Control, Crystal A. Wilbanks

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Acceptable solutions to animal damage problems must consider the social and recreational values of wildlife, regulation of population levels, potential hazards of chemical use, human safety and disturbance to biotic communities. The objective should be to reduce harm and economic loss of livestock to an acceptable level. This paper, reviews alternative, i.e. nonlethal, predator management methods. Alternative methods include guard animals, fencing, repellents, frightening devices and perhaps someday, immuno-contraception. The intent of animal damage control should be an integrated pest management approach tailored to fit the individual landowner's needs.

Historical Perspective On Coyote Control Methods In Texas, Robert L. Phillips, Gary L. Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A variety of control methods used over an 80-year period (1915–1995) contributed to the effective and successful coyote (Canis latrans) damage management program that exists in Texas today. Traps, toxicants, shooting, denning, and dogs were important during the early years of the Texas Animal Damage Control Service (TADCS) program. Aerial hunting and snares evolved as important control tools following the ban on strychnine and Compound 1080 in 1972. The livestock protection collar (LPC) has received increased use in recent years and has been useful in resolving difficult depredation problems. ADC policy along with changing state and federal regulations …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults

Biosystems and Agricultural Engineering Faculty Publications

A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …

Impacts Of Irrigation Development On Anadromous Fish In The Yakima River Basin, Washington, Robert L. Tuck

All Master's Theses

Prior to Euroamerican development, the Yakima River Basin was a major producer of salmon. Total runs of approximately 800,000 have declined to 3,000-5,000, or less than 1% of original run size. Three species are extinct in the basin, including summer chinook, coho, and sockeye.

Irrigation development, including the construction of unscreened diversions, the blockage of spawning and rearing habitat by reservoir dams, and the dewatering of spawning and rearing habitat, began in the mid-1800's and today totals approximately 500,000 acres. Historical records provide a wealth of information documenting irrigation development and its consequences on anadromous fish populations.

Birds Associated With Blackbird Spring Feeding Sites In South Dakota, George M. Linz, David L. Bergman, William J. Bleier

United States Department of Agriculture Wildlife Services: Staff Publications

From 2 to 16 April 1993, we conducted road-side surveys of birds using harvested fields of small grains, soybeans, and wm within 8 km of two blackbird roosts in east central South Dakota. Blackbirds, waterfowl, killdeer, homed larks, ring-necked pheasants, and western meadowlarks were the most common buds recorded. The frequencies of blackbirds, non-game birds, terrestrial game birds, and waterfowl was not equally distributed within the three habitats (P = 0.U.23).

Radon Reduction, Improvement Of Indoor Air Quality, And Energy Savings Through An Original Solar Ventilation System, Heather E. Rhoads

Dissertations and Theses @ UNI

This study evaluated the improvement of indoor air quality and energy savings achieved, by an original solar ventilation system installed at test sites exhibiting elevated radon levels. Conventional residential energy conservation measures that limit air exchange rates between the indoors and outdoors have been shown to increase concentrations of radioactive radon decay products as well as other indoor air contaminants. Growing concern about radon lung cancer risks, carbon monoxide poisoning, and the "sick building syndrome" have increased demand for improved indoor air quality. Due to added heating and cooling loads, ventilation generally incurs substantial installation and operational costs. All commercially …

Viticulture research reports

A course run by the Department of Agriculture, Western Australia, August 1995.

The purpose of this publication is to clarify the role fertilisers play in commercial table grape production and to detail methods of selecting fertilisers. This selection process however is not easy as there are over 600 registered fertilisers in Western Australia.

In deciding which is the best fertiliser for a particular property many factors have to be considered. These include:

* Age of vine

* Rootstock

* Variety of table grape

* Soil type

* Soil chemistry

* Irrigation methods

* Previous fertiliser history Previous yield, vigour and …

Feeding Responses To Predator-Based Repellents In The Mountain Beaver (Aplodontia Rufa), Gisela Epple, J. Russell Mason, Evgueny Aronov, Dale L. Nolte, Richard Hartz, Ron Kaloostian, Dan Campbell, Amos Smith Iii

United States Department of Agriculture Wildlife Services: Staff Publications

Predator odors have potential as feeding repellents for mammalian herbivores, including Aplodontia rufa, the mountain beaver. However, the repellency of major chemical constituents of natural predator scents for this species has not been evaluated. In this study, the effects of several synthetic sulfur compounds from predator scents on feeding by mountain beavers were assessed and compared to the effects of coyote (Canis latrans) urine. Retrieval of food by mountain beavers from bowls scented with either coyote urine, diluted with water to different concentrations, synthetic components of predator scents, or control odorants was studied. The following synthetic compounds …

Disease And Coyotes In Texas, Danny B. Pence

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The coyote (Canis latrans) population in southern Texas has a recurring group of 3 common helminths and several peripheral species of lesser importance. Although recurrent group analyses have not been applied to other macro- or microparasite communities, there are certain infectious agents with high prevalences that could form recurrent groups, and that are potentially important in tams of impacting host population (i.e. coyote) abundance. While the current rabies epizootic involving coyotes in southern Texas is of public health concern, it probably will not have a major impact on the coyote population. Most likely, the net effect of canine …

A Comparison Of Plotless Density Estimators Using Monte Carlo Simulation, Richard M. Engeman, Robert T. Sugihara, Larry F. Pank, William E. Dusenberry

United States Department of Agriculture Wildlife Services: Staff Publications

We conducted an extensive simulation study to compare the performance of a large group of plotless density estimators (PDEs) to obtain clarification of their relative performance in a diversity of sampling situations. The PDEs studied included well-known ones from the literature plus some extensions and modifications introduced here. The simulations cover 96 combinations of 6 spatial patterns, 4 sample sizes, and 4 population densities. We made comparisons within classes of similar estimators, and we indicate the best-performing PDEs out of the complete set studied. Over all spatial patterns, the angle-order estimator with measurements to the third closest individual in each …

Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen

KWRRI Research Reports

This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO₃^- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal …
