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.

Florida's Nuisance Alligator Control Program, Michael L. Jennings, Allan R. Woodward, Dennis N. David

Wildlife Damage Management Conference

The recovery of alligators from centuries of exploitation, coupled with a burgeoning human population in Florida has resulted in an increasing number of problem animals and alligator attacks. In response to this problem, the Florida Game and Fresh Water Fish Commission implemented a nuisance alligator control program in 1978. A mean of 2513 nuisance alligators per year was harvested during the period 1978 to 1988. The number of alligator complaints, nuisance alligators harvested, and alligator attacks increased significantly over the period (P=0.0003, P=0.0001, and P=0.04). The value of alligator meat remained stable at about $5.00/pound over the same period, while …

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 …

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 …

Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa Jr., James E. Forbes

Wildlife Damage Management Conference

The New York State Cooperative Coyote Damage Control Program was established in late 1986 through a cooperative agreement between the New York State Department of Agriculture and Markets (NYSDAM) and USDA, APHIS, ADC in response to escalating complaints of coyote (Canis latrans) depredations on sheep from 1980-85. Ten counties with histories of and/or potential for coyote/livestock conflicts were identified and targeted for publicity and primary program emphasis. Program staff received 58 reports of coyote depredations on 182 sheep from 32 producers in the ten target counties and seven outlying counties from May 1987 through May 1989, and verified …

Extent And Nature Of Deer Damage To Commercial Nurseries In New York, Roger W. Sayre, Daniel J. Decker

Wildlife Damage Management Conference

We surveyed nursery producers in New York to determine the extent, nature and economic impact of deer damage to their operations, and to assess their attitudes towards deer. Seventy-three percent of the producers experienced deer damage to their crops in 1988. Average costs for replacement were nearly $6,000 per grower for those reporting damage estimates (and over $8,000 if 1 extreme value was included). Statewide damage estimates ranged from $500,000 to $1.2 million (depending on assumptions). Forty-six percent used damage control, which cost an average of about $2,000 per grower. More than 80% of the producers were classified as "nonaccepting" …

Demonstration Electric Fences To Control Black Bear Damage To Apiaries In New York State, Janet L. Sillings, Thomas N. Tomsa Jr., James E. Forbes

Wildlife Damage Management Conference

The New York State black bear (Ursus americanus) population, approximately 4,000 animals (Clarke 1977), causes damage to apiaries in the catskill, Adirondack, and Southern Tier regions of the state. During 1987, 1988, and 1989, USDA Animal Damage Control (ADC) administered a program in New York to control bear damage to apiaries. Control activities were carried out pursuant to a Cooperative Agreement between ADC and the New York State Department of Agriculture and Markets, and were supported by matching Federal-State contributions. Program objectives were beekeeper education aimed at preventing bear damage and for the construction of demonstration temporary electric …

The Role Of Private Enterprise In Wildlife Damage Control, Lynn Braband

Wildlife Damage Management Conference

In addressing the role of private enterprise in wildlife damage control, I will not be bringing the final word or a comprehensively exhaustive report. Rather, I will be presenting some perspectives as the representative of a firm with extensive involvement with wildlife damage control as a business. My comments will be divided into why, what, how, and the future.

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D.

Faculty Works: CERCOM (1977-2016)

A periodic pause to intensely observe a singularly unique ecosystem sharpens one's awareness of this diverse world of ours, especially, as the author notes, if one observes a transitional ecosystem whose ecological treasures are hidden or maybe obscured by a tidal sediment's resemblance to a large, rotten cheese! "It smells, is slimy and sticky, is punched with holes and crowded with various worms." Sounds good to me! Reise's "pause" encompasses 10 years in which he investigated the Wadden Sea mudflats near the border between West Germany and Denmark. He uses this site to discuss the biotic and abiotic interactions within …

Phase I - Preconstruction Progress Report For Biological Monitoring Of The John U. Lloyd Beach Renourishment, Richard E. Dodge, Steven C. Hess, Charles G. Messing, Glenda Kelley

Marine & Environmental Sciences Faculty Reports

In 1987, Nova University (Contractor) with ERM South (Subcontractor) was awarded a contract to provide biological monitoring services for the John U.

Field monitoring took place in February and March, 1989. Laboratory work has continued from March, 1989 to present. The renourishment dredging took place from May 16, 1989 to July 14, 1989. Approximately 603,000 cu yds of sediment were removed and subsequently emplaced on 1.6 miles of shoreline. Within the next 6 months, Broward …

Toxicology Of Synthetic Pyrethroids In Aquatic Organisms: An Overview, Steven P. Bradbury, Joel R. Coats, D. M. Symonik, S. D. Dyer, L. K. Timson, G. J. Atchison

Steven P. Bradbury

The aquatic toxicology of the photostable synthetic pyrethroid insecticides as it affects two important groups of susceptible organisms — fish and aquatic insects — is discussed. The sensitivity of these aquatic species to the pyrethroids is dependent on several factors, including toxicokinetics, target site (nervous system), sensitivity and possible secondary mechanisms of action, as well as chemical and physical properties of the aquatic medium that influence toxicity and bioavailability. Uptake rates and routes of fenvalerate greatly affected the toxicity of fenvalerate to mosquito larvae. LD50 values were determined for cuticular and dietary exposure routes by utilizing radiolabeled fenvalerate at the …

Effect Of Photoperiod On Developmental Morphology And Enolase Isoenzyme Immunohistochemistry In Rat And Djungarian Hamster Superficial Pineal Glands, Chalmer D. Mcclure

Loma Linda University Electronic Theses, Dissertations & Projects

The best understood functional activity of the pineal gland is its diurnal production of melatonin in response to environmental lighting cues. Several enzymes of the melatonin pathway respond to daily photoperiod changes, for example hydroxyindole-O-methyltransferase (HIOMT) and serotonin N-acetyltransferase (SNAT). Increased levels of the glycolytic enzyme neuron-specific enolase (NSE) are thought to reflect increased physiological demands placed on neurons and neuroendocrine tissues. Homodimer non-neuronal enolase isoenzyme (NNE) is immunolocalized to cells, and the hybrid enolase (consisting of subunits from NSE and NNE) has been seen in cerebellar stellate and basket cells. Although not rate limiting, concentrations of both NSE and …

Winchester Sub-Catchment Management Plan, Vivian T. Read

Soil conservation survey collection

The 590 Ha Winchester sub-catchment has no apparent external drainage. Groundwater levels are rising causing site specific problems. Wind erosion has severely affected some areas.The objective of this report is to provide a sub-catchment management plan that is based on sustainable agricultural systems and a hydrological equilibrium. The recommendations aim to meet this objective in the long term. Recommendations to achieve short term results are considered separately. These measures have relatively high installation and maintenance costs. They should be considered as interim management methods until the recommendations for long-term control become effective (perhaps 3 - 5 years after implementation).

Testing Macroevolutionary Hypotheses With Cladistic Analysis: Evidence Against Rectangular Evolution, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

The properties of cladistic data sets from small monophyletic groups (6-1 2 species) are investigated using computer simulations of macroevolution. Two evolutionary models are simulated: gradualism and the punctuated-equilibrium hypothesis. Under the conditions of our simulations these two models of evolution make consistently different predictions about the distribution of autapomorphies among species. When strict stasis is enforced, the punctuated-equilibrium hypothesis predicts that the most expected number of autapomorphies per species will be zero, no matter how many characters are used in the analysis. As the number of characters used in the analysis increases, the distribution of the number of autapomorphies …

Simultaneous Determination Of 3-Methoxy-4-Hydroxyphenyl-Glycol, Homovanillic Acid, And 5-Hydroxyindoleacetic Acid In Plasma By High Performance Liquid Chromatography, Yung-Te Tseng

Chemistry & Biochemistry Theses & Dissertations

A rapid, reliable, and sensitive method for simultaneous determination of 3-methoxy-4-hydroxyphenylglycol (MHPG), Homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5- HIAA) in plasma is described. The method is based on high performance liquid chromatography with electrochemical detection. Samples were filtered with Amicon Centrifree micropartition systems and extracted with organic solvent before chromatography. Chromatographic separation of sample components was achieved isocratically in a C18 reverse-phase column. Quantitation was performed by measuring the peak height ratios of the sample components to an internal standard. Analytical recoveries ranged from 50.78 (SD 4.2%) to 67.94 (SD 3.28). Within-run coefficient of variations (CVs) ranged from 3.78 …

Mounting Sex Pheromone: A Novel Pheromone Responsible For Mate Recognition In The Ixodidae, Jgc Hamilton

Theses and Dissertations in Biomedical Sciences

Cholesterol oleate was demonstrated to be the cuticular contact sex pheromone of Dermacentor variabilis. This pheromone which has been termed the Mounting Sex Pheromone (MSP) was also demonstrated to be present on the surface of D. andersoni, Amblyomma maculatum and A. americanum. This contact sex pheromone enables males excited and attracted by 2,6-dichlorophenol to identify the female as a potential mating partner. The MSP is the second in the series of three sex pheromones guiding the hierarchy of behavioral responses which constitute tick courtship behavior. Tests with D. variabilis and D. andersoni showed that this pheromone …

The Temporal And Spatial Distribution Of Blue Crab Larvae On The Mid-Atlantic Bight Adjacent To The Chesapeake Bay, 1982-1983, Lyle Michael Varnell

OES Theses and Dissertations

Recruitment processes are important information for the management of commercially and recreationally exploited marine species. Recruitment processes of the Chesapeake Bay's most important commercial and recreational species, the blue crab, are unknown, due in part to the lack of knowledge of the processes directly preceeding recruitment.

The present study was undertaken to investigate and explain the movement and developmental patterns of blue crab larvae while offshore. Interannual and intraseasonal variations of these patterns were also examined.

Sampling occurred from May to November during 1982 and 1983. Larvae were collected at three depths (neuston layer (upper 10 cm), one meter and …

Picoplankton/Phytoplankton Dynamics In Hampton Roads, Virginia, Leslie E. Dorworth

OES Theses and Dissertations

The biomass distribution of the three main size components of the phytoplankton (net, nano, and picoplankton) was examined in the lower Chesapeake Bay. Work was done at two stations during the spring and neap tidal cycles when freshwater flow into the bay was at its seasonal minimum and maximum. Emphasis was placed on how the picoplankton ( < 2.0 μm, > 0.2 μm) reacted during the sampling period.

Picoplankton made up approximately 13% of the total biomass, during the observed time period, at the more oceanic station. The picoplankton fraction contributed up to 16% of the total biomass at the estuarine station. From this …

The Remipedia (Crustacea): A Study Of Their Reproduction And Ecology, Jill Yager

Biological Sciences Theses & Dissertations

Remipedes are an unusual group of troglobitic crustaceans that live exclusively in anchialine caves. Since their discovery in 1979, nine species have been described, seven of which are found in caves in the West Indies, one from the Yucatan peninsula of Mexico and one from the Canary Islands. Most of what is known about these animals has come mainly from taxonomic descriptions. Little has been published about their reproductive biology or ecology. The objectives of this dissertation were to investigate the reproductive biology and ecology of the remipedes inhabiting Sagittarius Cave on Grand Bahama Island, Bahamas.

Sagittarius Cave was chosen …

A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill

Reports

EXECUTIVE SUMMARY

1. In the Spring 1988, 2,145 striped bass were tagged in the James River.

2. The mean size of striped bass tagged in 1988 (351.6 mm) was 117.9 mm smaller than mean size in 1987. The difference may be due to different locations and times of tagging.

3. The dominant age group in 1987 was the 1982 year class but in 1988 the dominant age group was the 1984 year class. This difference may also be accounted for by different locations and times of tagging.

4. The exodus of the mature fish out of the river after spawning …

Fault Tolerance In A Very Large Database System: A Strawman Analysis, Amit P. Sheth

Kno.e.sis Publications

A simple model is used to study the effect of fault-tolerance techniques and system design on system availability. A generic multiprocessor architecture is used that can be configured in different ways to study the effect of system architectures. Important parameters studied are different system architectures and hardware fault-tolerance techniques, mean time to failure of basic components, database size and distribution, interconnect capacity, etc. Quantitative analysis compares the relative effect of different parameter values. Results show that the effect of different parameter values on system availability can be very significant. System architecture, use of hardware fault tolerance (particularly mirroring), and data …

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle

Publications (WR)

Temporal and spatial patterns of age 0 threadfin shad (Dorosoma petenense) abundance and growth, in the Overton Arm of Lake Mead, were examined to evaluate the effects of resource availability on the young fish. This was part of a larger, game fishery enhancement study (Lake Mead Fertilization Project), designed to assess feasability of increasing survivorship of larval/juvenile shad by boosting phosphate levels, thereby increasing algal and zooplankton biomass, during the shad spawning period. Shad are the primary forage base for the striped bass (Morone saxatilis) and black bass (Macropterus salmoides) fisheries. Weekly samples were …
