Identification And Quantitation Of Volatile Amines In Marine Sediments, Chuen Mei Huang Oct 1989

Identification And Quantitation Of Volatile Amines In Marine Sediments, Chuen Mei Huang

Chemistry & Biochemistry Theses & Dissertations

Pore waters which were taken from sediments of the Chesapeake Bay were analyzed to determine the presence of volatile amines. A purge-and-trap technique was used to concentrate the amines. Then, following derivatization with heptaflourobutyric anhydride, the HFBA-amines were analyzed by gas chromatography with electron capture detection and with mass spectrometric detection. One secondary amine, diethylamine with a concentration of 0.3-0.6 uM, was found in a total of three pore water samples from cores collected on two different dates. A primary amine, sec-butylamine with a concentration of O. 05 AIM, was also found in one of these same samples. Another primary …


An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Alan May, Dennis Slate Sep 1989

An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Alan May, Dennis Slate

Wildlife Damage Management Conference

An increase in the use of plastic tubing systems to collect sap from sugar maples (Acer saccharum) has allowed syrup producers to boost production in recent years, but not without cost. Rodents gnawing on tubing, spouts, and fittings may cause damage in excess of $300,000 annually in Vermont, the largest maple producing state. Red squirrels (Tamiasciurus hudsonicus), gray squirrels (Sciurus carolinensis), and chipmunks (Tamias striatus) appear to be responsible for the majority of damage. Other species including flying squirrels (Glaucomvs sabrinus), white-footed mice (Peromvscus leucopus), porcupines (Erethizon …


Preliminary Evaluation Of A Granular Trimethacarb Formulation For Deterring Grazing By American Coots, Michael L. Avery, Curtis Nelms, J. Russell Mason Sep 1989

Preliminary Evaluation Of A Granular Trimethacarb Formulation For Deterring Grazing By American Coots, Michael L. Avery, Curtis Nelms, J. Russell Mason

Wildlife Damage Management Conference

In a 0.2 ha flight pen, group of 4 American coots were tested to determine if their grazing activity could be affected by application of a registered granular-trimethacarb insecticide. In the 3 days following treatment (3 kg/ha, a.i.), grazing activity in the treated portions of the 200 m2 experimental plots was reduced an average of 47%. Overall use of the treated areas followed a similar pattern but was less consistent among groups. The addition of methylpyrazine, a strong odorant, produced a strong initial suppression of grazing activity in the treated halves of the plots. However, subsequent rain and a …


Economic Impact And Control Of Wading Birds At Arkanas Minnow Ponds, Michael D. Hoy, Jeffery W. Jones, Albert E. Bivings Sep 1989

Economic Impact And Control Of Wading Birds At Arkanas Minnow Ponds, Michael D. Hoy, Jeffery W. Jones, Albert E. Bivings

Wildlife Damage Management Conference

Esophageal/stomach contents of 172 little blue herons (Egretta caerulea), great egrets (Casmerodius albus), snowy egrets (Egretta thula), and great blue herons (Ardea herodias) were analyzed to estimate their consumption of golden shiners. Mean and maximum number of golden shiners consumed/bird, as well as the mean total length of golden shiners consumed by each wading bird species was determined. Loss estimates varied by wading bird species and ranged from $0.10 - $1.12/bird/feeding. Loss estimates reflect the severity of problems with wading birds on minnow ponds and the need to reduce losses by use …

Effects Of Free-Ranging Cats On Wildlife: A Progress Report, J.S. Coleman, S.A. Temple Sep 1989

Effects Of Free-Ranging Cats On Wildlife: A Progress Report, J.S. Coleman, S.A. Temple

Eastern Wildlife Damage Control Conference: 4th (1989)

We have embarked upon a three-year study to determine the density and distribution of free-ranging cats (Felis catus) and their effects on prey populations in rural Wisconsin. The effects of predation by free-ranging cats on wildlife populations are potentially great and have not been adequately accounted for in wildlife management programs. In rural Illinois there was an average of 5.6 free-ranging cats per farm (Warner 1985). If densities elsewhere are similar, then a state such as Wisconsin, with over 200,000 active and retired farms, could have over 1 million free-ranging cats on farms. In other studies (Bradt 1949, …


Beaver And Beaver Dam Removal In Wisconsin Trout Streams, Larry Dickerson Sep 1989

Beaver And Beaver Dam Removal In Wisconsin Trout Streams, Larry Dickerson

Eastern Wildlife Damage Control Conference: 4th (1989)

Beaver (Castor canadensis) dam building activities create many long-term affects on stream ecosystems. Beaver dams may negatively influence trout fisheries by creating physical barriers to spawning areas, increasing sediment retention, and increasing water temperatures. The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Animal Damage Control (ADC) program in Wisconsin, entered into cooperative agreements with the Wisconsin Department of Natural Resources (WDNR) and the U.S. Forest Service (USFS) on the Nicolet National Forest from June through September, 1988, to remove beaver and beaver dams from priority classed trout streams. Four hundred and eight beaver …


Evaluation Of A Canada Goose Call-Activated Switch For Crop Damage Abatement, James W. Heinrich, Scott R. Craven Sep 1989

Evaluation Of A Canada Goose Call-Activated Switch For Crop Damage Abatement, James W. Heinrich, Scott R. Craven

Eastern Wildlife Damage Control Conference: 4th (1989)

Damage and nuisance problems caused by Canada geese (Branta canadensis) are difficult to control with current abatement technology. We tested the efficacy of a goose call-activated switch as a modification for propane exploders (gas cannons), using recorded Canada goose calls and live goose trials. We recorded a 30 m range for the switch and found that it was activated by a range of non-target sounds. The development of this device and the technology involved are discussed. The call-activated switch is not a useful tool in reducing Canada goose damage in crop fields.

Canada geese frequently feed on agricultural …


Wolf Depredation On Livestock In Minnesota Annual Update Of Statistics - 1988, William J. Paul Sep 1989

Wolf Depredation On Livestock In Minnesota Annual Update Of Statistics - 1988, William J. Paul

Eastern Wildlife Damage Control Conference: 4th (1989)

Depredation by wolves (Canis lupus) on livestock and poultry in Minnesota is a problem for some producers. A small percentage of the farms in the wolf range are affected annually and a few of these farms suffer substantial monetary loss in a given year. From 1976 through 1988, the number of farms suffering verified wolf depredations ranged from 9 to 38 (x = 23) per year out of about 7,200. From 1977 through 1988 the highest cattle losses claimed by farmers were 0.45 per 1,000 available in 1979; the highest sheep losses claimed were 2.66 per 1,000 available …


Ecologically Sensitive Management Options For Bats, Paul B. Robertson Sep 1989

Ecologically Sensitive Management Options For Bats, Paul B. Robertson

Eastern Wildlife Damage Control Conference: 4th (1989)

Over the past decade, there has been a dramatic, positive shift in the public image of bats in the United States (Tuttle 1988a). This shift is particularly impressive in light of the inappropriate and poor public image that bats have suffered in most western nations in the last century. Over the past decade, a sizeable segment of the U.S. public, as well as local, state and national officials, have been educated to the ecological and economic value of bats which results from their insectivory and plant pollination activities (Olkowski and Olkowski 1989, Tuttle 1988b). The fact that they pose a …


An Automatic Trigger For Bird Frightening Devices, Steve Price, John Adams Sep 1989

An Automatic Trigger For Bird Frightening Devices, Steve Price, John Adams

Eastern Wildlife Damage Control Conference: 4th (1989)

This triggering unit for animal frightening devices was developed because of an expressed need for a more effective method of breaking up starling and grackle roosts. The USDA, Animal Damage Control (ADC) office in Louisville, KY suggested that a device which detected the presence of the birds before activating and then emitted different sounds would be much more effective than single functioning devices on timers. Existing frightening devices have limited effectiveness because the birds become accustom to the repeated and periodic actuations of the same thing over and over again. In November of 1986, Mr. Bernice Constantin, District Supervisor for …

Persistence Of Tartrazine In Marking Sheep Wool, Richard J. Burns, Peter J. Savarie Sep 1989

Persistence Of Tartrazine In Marking Sheep Wool, Richard J. Burns, Peter J. Savarie

Wildlife Damage Management Conference

Tartrazine was examined as a possible replacement marker for rhodamine B in the Livestock Protection Collar. Test solutions were formulated in six combinations; tartrazine at 0.5%. and 1.0% concentrations, with and without compound 1080, and with and without nigrosin black. Each solution was examined for persistence of color in the laboratory and when applied to the wool of dried sheep hide. Hide pieces were allowed to weather naturally or were sprinkled to simulate rain. Tartrazine alone was also tested at concentrations of 0.5%. and 1.0% on the necks of sheep. Over a 3-month period, no fading was noted in the …


Depredation Permits For Migratory Birds, Larry L. Hood Sep 1989

Depredation Permits For Migratory Birds, Larry L. Hood

Wildlife Damage Management Conference

All of the native species of birds in the United States are protected by either federal or state laws. Under the Migratory Bird Treaty Act, the federal government has formulated regulations that assist in controlling protected species that cause economic damage or health hazards. These regulations are in Subpoint D of Part 21, Title SO Code of Federal Regulations, and may take the form of standing depredation orders or permits issued to kill those species that cause problems.


A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc Sep 1989

A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc

Wildlife Damage Management Conference

Damage caused by the feeding of raccoons (Procyon lotor) on stalks of sugarcane (Saccharum sp.) has occurred for several years on the 200-acre U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) research farm located near Houma, Terrebonne Parish, Louisiana. Damage begins when sugarcane mature internodes begin to from in late June and early July, and continues until the completion of harvest in late December. Raccoons appear to prefer varieties having low fiber and/or high sugar content and can severely damage these varieties (personal observation). Depredation by these animals frequently result in loss of data as preferred …

Fertility Control As A Tool For Regulation Of Wildlife Populations, U. S. Seal Sep 1989

Fertility Control As A Tool For Regulation Of Wildlife Populations, U. S. Seal

Wildlife Damage Management Conference

Biological control of reproduction and fertility is a normal part of the life history of all organisms. Control mechanisms allow timing of reproduction with respect to age, time of day, season, and other periodic environmental events. Further modulation can occur with variations in temperature, rainfall, nutrition, and health status. Interactions with other members of the species, ranging from pherohormonal stimulation of estrus to social delay of puberty and breeding to infanticide, provide further constraints upon fertility and recruitment. All of these processes ultimately act through molecular neuroendocrine mechanisms that are under genetic control and are subject to natural selection and …


A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson Sep 1989

A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson

Wildlife Damage Management Conference

Commercial urban /industrial structural pest bird control is approaching a time of crisis. Several long-standing toxicants that have been used as a major part of pest bird control programs are either suspended, at risk of suspension, or have had their production terminated by the manufacturer. "Environmental groups" are up in arms about the use and misuse of pesticides. Lawsuits have been filed to stop the use of some products, and political pressure has brought about reviews of some pesticide products on both the state and federal levels. EPA has seemed to have a "get tough" policy in its reregistration guidelines, …

Wildlife Disease Concerns In Animal Damage Control, Sarah Shapiro Hurley

Wildlife Damage Management Conference

There are many facets to the topic of wildlife disease concerns in animal damage control, but the area that I have chosen to discuss is that of zoonotic disease - diseases which are transmissible in nature between humans and other animals. The list of zoonoses is extensive and in the time available only a few can be reviewed.

Wildlife Damage To Crops: Perceptions Of Agricultural And Wildlife Professionals In 1957 And 1987, Michael R. Conover, Daniel J. Decker

Eastern Wildlife Damage Control Conference: 4th (1989)

We surveyed state wildlife agencies, state agricultural departments, Wildlife Extension Specialists, U.S.D.A. Animal Damage Control agents, and state Farm Bureau officials to develop a national perspective of wildlife damage to agricultural crops in the U.S. A broad concensus existed that wildlife damage was a major problem, although groups often differed in their perceptions of the seriousness of specific problems. The complexity of the wildlife damage problem was apparent in that 27 different wildlife species were cited as causing the greatest problem to a state's farmers. Nevertheless, 38-80% of the respondents from every group surveyed stated that deer were their worst …
