Golf Courses In Southern Nevada Will Significantly Impact The Water Management Efforts By Using Recycled Water Rather Than Potable Water To Irrigate Their Turf, Sean D. Ainsworth Apr 1999

Golf Courses In Southern Nevada Will Significantly Impact The Water Management Efforts By Using Recycled Water Rather Than Potable Water To Irrigate Their Turf, Sean D. Ainsworth

UNLV Theses, Dissertations, Professional Papers, and Capstones

As the number of people continually move to the Las Vegas Valley and take up residence, the possibility of "running out of water" can become a reality. Having large water users (i.e. golf courses) irrigate their turf with recycled water, they will significantly impact the water management efforts in the Las Vegas Valley. When each course is irrigating their turf with recycled water, this will help ease the drinking water demand in the valley, especially during the peak demand season (summer).

Characterization And Identification Of A Sludge-Associated Bacterial Isolate, Abiodun O. Adibi, Derrell Mcpherson, Minna Laine

Virginia Journal of Science

During a metal speciation study, an unusually high retention of lead ·was observed when lead solution was percolated through a column packed with sludge compost obtained from Hampton Roads Sanitation department. A bacterium was isolated from the sludge compost and identified as Bacillus sphaericus using electron microscopy, whole cell fatty acid analysis (Midi System) and Biolog GP Microplate. The isolate grows in broth and agar media containing up to 800 µM lead. Lead accumulation study using atomic absorption spectrophotometer indicates that the isolate adsorbs lead. Lead adsorption is pH dependent. The isolate contains a plasmid of approximately 40 -50 kbp …


The Feasibility Of Controlling The Brown Treesnake In Small Plots, Gordon H. Rodda, Thomas H. Fritts, Earl W. Campbell Iii Apr 1999

The Feasibility Of Controlling The Brown Treesnake In Small Plots, Gordon H. Rodda, Thomas H. Fritts, Earl W. Campbell Iii

United States Department of Agriculture Wildlife Services: Staff Publications

There is an urgent need to provide snake-free or snake-reduced habitats for the wildlife species on Guam that have declined or disappeared as a result of predation by the Brown Treesnake, Boiga irregularis (Savidge, 1987; Fritts, 1988; Rodda and Fritts, 1992; Rodda et al., this volume, Chap. 2). At present, we know of no practical techniques for reducing or eradicating the snake throughout Guam, a densely populated island of 54,100 ha. Conserving native wildlife and reducing the incidences of snakes boarding ship and aircraft may not require the elimination of snakes from the entire island, however. Elimination of snakes from …

An Overview Of The Biology Of The Brown Treesnake* (Boiga Irregularis), A Costly Introduced Pest On Pacific Islands, Gordon H. Rodda, Thomas H. Fritts, Michael J. Mccoid, Earl W. Campbell Iii

United States Department of Agriculture Wildlife Services: Staff Publications

The 20-30 species of the genus Boiga (Colubridae, Boiginae) range from tropical Africa through southern Asia to Melanesia and Australia (Leviton, 1968). Collectively, they are known as catsnakes, mangrove snakes, or treesnakes (Obst et al., 1988; Greene, 1989). The common name "catsnakes" is sometimes used for snakes in the genus Telescopus as well (Obst et 1, 1988).

Members of the genus Boiga are nocturnal, oviparous, opisthoglyphic, euryphagic, and slender; they have vertical elliptical pupils (thus “cat” snakes) set in large eyes, and short, blunt heads that are noticeably larger than their necks. With one exception they are arboreal or semiarboreal …

Methods For The Diagnosis Of Acute 3-Chloro-P-Toluidine Hydrochloride Poisoning In Birds And The Estimation Of Secondary Hazards To Wildlife, John J. Johnston, Daniel B. Hurlbut, Michael L. Avery, Jack C. Rhyan Mar 1999

Methods For The Diagnosis Of Acute 3-Chloro-P-Toluidine Hydrochloride Poisoning In Birds And The Estimation Of Secondary Hazards To Wildlife, John J. Johnston, Daniel B. Hurlbut, Michael L. Avery, Jack C. Rhyan

United States Department of Agriculture Wildlife Services: Staff Publications

Female boat-tailed grackles poisoned with 3-chloro-p-toluidine hydrochloride (CPTH) were analyzed by necropsy and gas chromatography–mass spectrometry (GC-MS). The necropsies identified the presence of a white precipitate in the pericardium, which had been previously reported as a characteristic of CPTH-exposed birds. The GC-MS method, which utilized deuterated CPTH as a surrogate, quantified CPTH residues in the breast tissue and gastrointestinal tract of CPTH-exposed birds. Comparison of these techniques indicated that the GC-MS method was more accurate for assessing CPTH poisoning in birds. Regression analyses of consumption versus residue data indicated that the sum of breast and gastrointestinal residues can …

Fisheries Research Report No. 113 - Catch, Effort And The Conversion From Gill Nets To Traps In The Peel-Harvey And Cockburn Sound Blue Swimmer Crab (Portunus Pelagicus) Fisheries, Roy Melville-Smith, Mark Cliff, Sonia M. Anderton

Fisheries Research Reports

Over the last few years, there has been considerable interest on the part of commercial fishers to move away from using gill nets, the traditional method for fishing for blue swimmer crabs in Western Australia (WA), to fishing with traps. Blue swimmer crab fisheries in WA are regulated by effort controls and most gill net fishers are restricted to hauling 1,000 metres (1,200 metres in the case of Cockburn Sound) of gill net per day.

The fieldwork in this study was initiated in March 1994 in Cockburn Sound and in January 1996 in the Peel-Harvey Estuary. It was aimed at …

Institute for Sustainable Solutions Publications and Presentations

The last half-century has seen momentous and accelerating changes in humankind's economic activities, political relations, and social and demographic profile. A prominent feature of this change is the increasing scale of human impact on Earth's natural biophysical systems: the climate system, stratospheric ozone, biodiversity, terrestrial and marine food-producing ecosystems, and the great cycles of water, nitrogen, and sulfur (Meyer 1996, Vitousek et al. 1997). These systems sustain the conditions on which life depends, and their weakening may therefore have profound long-term implications for human population health (McMichael 1993, Last 1997).

Internal Temperature Of Douglas-Fir Buds Is Altered At Elevated Temperature, Martha E. Apple, Melissa S. Lucash, David M. Olszyk, David T. Tingey, Donald L. Phillips Feb 1999

Internal Temperature Of Douglas-Fir Buds Is Altered At Elevated Temperature, Martha E. Apple, Melissa S. Lucash, David M. Olszyk, David T. Tingey, Donald L. Phillips

Environmental Science and Management Faculty Publications and Presentations

Pseudotsuga menziesii (Douglas-fir) saplings were grown in sun-lit controlled environment chambers at ambient or elevated (4°C above ambient) temperature. We measured internal temperatures of vegetative buds with thermocouple probes and compared temperatures of normal buds and abnormal buds with loosened, rosetted outer scales in elevated temperature chambers. The abnormal buds had higher and earlier peak daily temperatures than normal buds. Elevated temperature may influence the internal temperature of buds and contribute to the development of abnormal, rosetted buds with loosened outer scales. Abnormal bud development may alter branching patterns and allometry of Douglas-fir trees subjected to climatic change.

Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss Jan 1999

Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss

Theses

An ecological risk assessment process requires a modeling tool that can adapt to changing environmental conditions. Computer simulation tools are a useful means to develop an ecological risk assessment, because if properly used they can provide an organized framework to evaluate multiple data sources, complex problems and hypotheses. An evaluation was completed of the University of Tennessee CHEMS-1 model that ranks and scores contaminant toxicity and exposure potential. Tantalum posed less of a hazard than hexavalent chromium to the terrestrial and aquatic animals. Although, results indicated that the vanadium compounds, in particular vanadium pentoxide, presented the greatest hazard, with hexavalent …
