Long Term Residual Effects Of A Nutrient Addition On A Barrier Island Dune Ecosystem, Susan M. Heyel

Biological Sciences Theses & Dissertations

In 1991, 150 m² were fertilized with nitrogen on three dunes on Hog Island, part of the Virginia Coast Reserve Long Term Ecological Research site, to examine plant community response to nitrogen addition. In 2000, the fertilized plots continued to exhibit a positive growth response. This study sampled the aboveground biomass, belowground biomass, and nutrient content of the experimental plots to examine the long- term patterns of nitrogen retention in a nitrogen limited system. Aboveground and belowground biomass was significantly greater in the fertilized plots than in the control plots. Aboveground biomass exhibited was significantly greater in control and …

Caffeine As A Repellent For Slugs And Snails, Robert G. Hollingsworth, John W. Armstrong, Earl Campbell

United States Department of Agriculture Wildlife Services: Staff Publications

Most commercial products for snail and slug control contain either metaldehyde or methiocarb as the active ingredient, the residues of which are not permitted in food crops in the United States. We have discovered that solutions of caffeine are effective in killing or repelling slugs and snails when applied to foliage or the growing medium of plants. Because caffeine is a natural product and is classified by the United States Food and Drug Administration as a GRAS (‘generally recognized as safe’) compound, it has potential as an environmentally acceptable alternative toxicant for the control of slugs and snails on food …

Methyl Anthranilate Aerosol For Dispersing Birds From The Flight Lines At Homestead Air Reserve Station, Richard M. Engeman, Jeffrey Peterla, Bernice Constantin

United States Department of Agriculture Wildlife Services: Staff Publications

The failure of traditional hazing methods to provide a lasting dispersal of birds from the flight lines at Homestead Air Reserve Station, Florida led to trials with Rejex-it® TP-40 methyl anthranilate (MA) formulation as an aerosol. A variety of civil, military and other government aircraft use the base, including combat aircraft which are particularly prone to bird air strikes due to low altitude, high speed flights. Migrating swallows and killdeer congregate at the airfield to forage on insects, and the large numbers of birds cause restrictions in airfield operations because of potential strike hazards with aircraft. MA applied by fogger …

Strategic Management Plan For Columbian Sharp-Tailed Grouse 2002, State Of Utah, Department Of Natural Resoures, Division Of Wildlife Resources

All U.S. Government Documents (Utah Regional Depository)

The Columbian Sharp-tailed Grouse (Tympanuchus phasianellus columbianus) is one of seven subspecies of Sharp-tailed Grouse. Historically, Columbian Sharp-tailed Grouse occurred within sagebrush-native bunch grass habitat throughout the intermountain region, extending from British Columbia, Washington, Idaho and Montana south through portions of Oregon, California, Nevada, Utah, Wyoming, Colorado and New Mexico. Sharp-tailed Grouse populations range-wide began declining during 1880-1920 (Bart 2000). By 1936, the range of distribution had been reduced by two-thirds (Hart et al. 1950). Currently, Columbian Sharp-tailed Grouse occur in only 5 % of their historic range-wide distribution and 4% of their distribution in Utah (Bart 2000). Within the …

Closing The Loop: Recycling, Reformulation, And Reuse In Prince Edward, Amelia, Buckingham And Cumberland Counties, Andrea Louise Bridge

Theses & Honors Papers

Everything we do to the land, air, and water affects our quality of life on this planet. Since the beginning of time, human beings have generated and discarded trash. As the pollution of the United States continues to grow so have the problems with our nation's landfills. Americans throw away an average of 3.5 pounds of garbage per person each day, or approximately 160 million tons of it per year. Studies have been conducted that show that the majority of our trash consists of paper, yard trimmings, metal, plastics, glass, food wastes, rubber, leather, textiles, and miscellaneous inorganic materials.

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

Separations Campaign (TRP)

The recovery of iodine released during the processing of used nuclear fuel poses a significant challenge to the transmutation of radioactive iodine. This proposal will develop and examine the use of Fullerene Containing Carbon (FCC) compounds as potential sorbents for iodine release from the reprocessing of nuclear fuel. This work will also include the development of bench-scale testing capabilities at UNLV to allow the testing of the FCC material in a simulated process off-gas environment. This experimental capability will also be used to test other potential sorbtion materials and processes, such as natural organic matter (NOM) and other promising alternatives. …

Quality Control For Usda Nrcs Sm–St Network Soil Temperatures: A Method And A Dataset, Q. Steven Hu, Song Feng, Garry Schaefer

School of Natural Resources: Faculty Publications

In 1991, the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) established its Soil Moisture–Soil Temperature (SM–ST) Pilot Network consisting of 21 stations in 19 states in the contiguous United States. At each station, soil temperatures were measured at up to six different depths from 5.08 to 203.20 cm (or 2–80 in.) below the surface. Before 1997, the observations were made every 6 h, and they increased to hourly beginning in 1997. The goal of this network is to provide near–real time soil temperature and soil moisture observations in different regions across the United States for agricultural and …

Discussion Paper : The Translocation Of Brown Trout (Salmo Trutta) And Rainbow Trout (Oncorhynchus Mykiss) Into And Within Western Australia., Western Australian Fisheries

Fisheries Management Papers

This discussion paper has been prepared to assist in the assessment of the possible impact of the translocation of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss), into and within Western Australia, for the purposes of recreational stock enhancement in public waters, non-commercial aquaculture on private properties and commercial aquaculture. In assessing the translocation of any aquatic species, economic and social benefits must be balanced with biological and environmental risks.
