A Strategy For Integrating Principles And Concepts Of Wildlife Damage Control Into The School Curriculum, Thomas A. Eddy Nov 1995

A Strategy For Integrating Principles And Concepts Of Wildlife Damage Control Into The School Curriculum, Thomas A. Eddy

Eastern Wildlife Damage Management Conference: 7th (1995)

This paper reports an approach to educating today's youth concerning the importance of regulating numbers of wildlife species that threaten property, products and health. The emphases are on preparing teachers to integrate principles and concepts into the existing curricular materials, justifying control measures with ecological understandings and economic is information and dealing effectively with sensitive animal rights issues. Opportunities for integration of specific wildlife damage control topics are suggested for lessons in the life sciences, social sciences, health, language arts and mathematics. Examples of conflict between groups of different opinions about the seriousness of a pest's activities or appropriateness of …

A Comparison Of Deer Hunter And Farmer Attitudes About Crop Damage Abatement In Michigan: Messages For Hunters, Farmers And Managers, Peter A. Fritzell Jr., Donna L. Minnus, R. Ben Peyton Nov 1995

A Comparison Of Deer Hunter And Farmer Attitudes About Crop Damage Abatement In Michigan: Messages For Hunters, Farmers And Managers, Peter A. Fritzell Jr., Donna L. Minnus, R. Ben Peyton

Eastern Wildlife Damage Management Conference: 7th (1995)

During the last 20 years several states have seen dramatic changes in the size of their white-tailed deer (Odocoileus virginianus) populations and also more frequent debates about how the deer resource should be managed. One central area of conflict between stakeholders involved in deer management is the issue of the lethal control of depredating deer, and how and when programs involving lethal control should be implemented. In the last decade, both Michigan farmers and deer hunters have organized special interest groups to express their dissatisfaction with deer population numbers, deer-caused crop losses, and/or the state's crop depredation control …

Rodent Damage Control In No-Till Corn And Soybean Production, Ron Hikes Nov 1995

Rodent Damage Control In No-Till Corn And Soybean Production, Ron Hikes

Eastern Wildlife Damage Management Conference: 7th (1995)

In recent years the primary cause of reduced plant stands in no-till crops planted into heavy residue has been small eared rodents called voles (Microtus spp.). Past research has indicated that severe stand reductions (80 to 100 percent) can occur if vole populations in the field exceed 75 per hectare (30 per acre) at planting time. This vole population should be considered intense. If field scouting about 30 days prior to planting reveals at least 12 active vole colonies per hectare (five per acre) an intense population can develop, and damage control measures should be planned. Of all …

Efficacy Of Shooting Permits For Deer Damage Abatement In Wisconsin, Rick R. Norton, Scott R. Craven Nov 1995

Efficacy Of Shooting Permits For Deer Damage Abatement In Wisconsin, Rick R. Norton, Scott R. Craven

Eastern Wildlife Damage Management Conference: 7th (1995)

The efficacy of out-of-season shooting permits for deer damage abatement in Wisconsin has not been critically evaluated. We used deer damage shooting permits to remove 21 antlerless deer (Odocoileus virginianus) from 7 heavily damaged alfalfa fields to evaluate subsequent impact on crop damage. Volunteer shooters, using permits issued to the landowners, hunted a minimum of 3 nights/week throughout the growth of the third alfalfa crop (Aug. 1 - late Sept.). We calculated the difference between the assessed damage to the second crop (untreated) and the third crop (treated) on treatment and control farms. We found no significant difference …

Survey Of Black Bear Depredation In Agriculture In Massachusetts, Sandra A. Jonker, James A. Parkhurst Nov 1995

Survey Of Black Bear Depredation In Agriculture In Massachusetts, Sandra A. Jonker, James A. Parkhurst

Eastern Wildlife Damage Management Conference: 7th (1995)

Black bear (Ursus americanus) depredation in agriculture has become an increasing concern in Massachusetts. Complaints from apiarists, corn growers, and livestock producers have increased 167% during the period 1980 to 1990, but whether this increase truly represents more depredation, response of bears to other factors, or simply better reporting/record keeping has not been determined. The bear population in Massachusetts from 1984 to 1989 increased 50°/a to approximately 700-750 animals statewide. Subsequent estimates (1995) have placed the bear population around 1,200 animals. Concurrent encroachment of human development into prime bear habitat also increased contact between bears and humans. During …

Mississippi's Beaver Control Assistance Program, 1989-1994, Philip Mastrangelo

Eastern Wildlife Damage Management Conference: 7th (1995)

Responding to landowner requests, the 1989 Mississippi Legislature created the Beaver Control Advisory Hoard and mandated it to develop a program which would ensure the control of beaver damage throughout Mississippi. The Advisory Board is comprised of the administrative heads of five state agencies: the Department of Wildlife, Fisheries, and Parks (chairperson), the Department of Transportation, the Cooperative Extension Service, the Forestry Commission, and the Department of Agriculture and Commerce. In cooperation with the U. S. Department of Agriculture, Animal and Plant Health Inspection Service, Animal Damage Control (ADC) program, the Advisory Board developed the Beaver Control Assistance Program (BCAP). …

Bat Exclusion Methods, William H. Kern Jr. Nov 1995

Bat Exclusion Methods, William H. Kern Jr.

Eastern Wildlife Damage Management Conference: 7th (1995)

This publication is intended to serve as a review of currently accepted methods of bat exclusion. Inappropriate house bat control methods are destructive to our decreasing bat populations and often cause additional problems for the building's owner or occupant. These problems include odor from dead bats, infestations of carrion-feeding flies, and increasing human and pet exposure to bats. Appropriate exclusion methods like winter structure modification for cave hibernating bats or one-way excluders using hardware cloth, plastic sheeting, or plastic bird netting are the best ways to protect these beneficial wildlife species and correct situations where humans and bats come into …

Relationships Between Wild Turkeys And Raccoons In Central Mississippi, Charles D. Lovell, Darken A. Miller, George A. Hurst, Bruce D. Leopold Nov 1995

Relationships Between Wild Turkeys And Raccoons In Central Mississippi, Charles D. Lovell, Darken A. Miller, George A. Hurst, Bruce D. Leopold

Eastern Wildlife Damage Management Conference: 7th (1995)

Reduced trapping and hunting of predators has led to concerns that increased predator densities may aged game species populations. Therefore, we investigated effects of predation on the wild turkey population on Tallahala Wildlife Management Area (TWMA), Mississippi, from 1984-94. We also determined trends in raccoon trapping and hunter harvest in Mississippi. Predation of nests (eggs), nesting hens, and points caused a population decline on TWMA. Most (88°!0) nest failures were caused by predation from 1984-94; raccoons were the dominant predator. Declining raccoon hunter harvest from 1980-94 was correlated with declining hunter effort. Trapping license sales and trapping harvest also declined. …

Wildlife Damage Control In Kansas: Private Operators And Public Agencies, L. Andrew Madison, Philip S. Gipson Nov 1995

Wildlife Damage Control In Kansas: Private Operators And Public Agencies, L. Andrew Madison, Philip S. Gipson

Eastern Wildlife Damage Management Conference: 7th (1995)

The private industry in wildlife damage control is expanding into territory predominantly occupied by public agencies in the past. There is a potential for overlap and competition in services provided by the public and private sectors in Kansas. We examined wildlife damage control activity reports from the Cooperative Extension Service (CES), Kansas Department of Wildlife and Parks (IDWP), and private nuisance wildlife control operators (NWCO) to determine the most common species controlled by each and their overlap in services across Kansas. The CES predominantly controlled coyotes (Canis latrans). KDWP primarily controlled beavers (Castor canadensis), deer ( …

The Professional Evolution Of Wildlife Damage Management, James E. Miller Nov 1995

The Professional Evolution Of Wildlife Damage Management, James E. Miller

Eastern Wildlife Damage Management Conference: 7th (1995)

The terns -- wildlife damage management, in lieu of animal damage control, vertebrate pest control, or nuisance animal control -- has become the currently recognized term for an area of wildlife management that a growing number of professionals spend a significant part of their time and/or career working in. The acceptance of this terminology is, however, a part of the continuing evolution of the profession and not simply a name change for political correctness. Admittedly, my purpose is not to validate or beg acceptance of this terminology. Rather, what I hope to do is to justify the underlying premise of …

A Historical Perspective Of Catfish Production In The Southeast In Relation To Avian Predation, Donald F. Mott, Martin W. Brunson Nov 1995

A Historical Perspective Of Catfish Production In The Southeast In Relation To Avian Predation, Donald F. Mott, Martin W. Brunson

Eastern Wildlife Damage Management Conference: 7th (1995)

Production of aquaculture species, especially catfish (Ictalurus punctatus) in the Mississippi Delta, is a relatively new and expanding industry. Catfish production represents the largest dollar value of the aquaculture industry, accounting for approximately 50% of the entire industry. Mississippi is responsible for 82% of the total U.S. catfish production. Fish-eating bird populations have capitalized on this new food source. Double-crested cormorants (Phalacrocorax sauritus), great blue herons (Ardea herodias) , and great egrets (Casmerodius albus) are the primary predators on catfish. Cormorant caused losses in excess of $2 million per year have been …

Extirpation Of A Recently Established Feral Pig Population In Kansas, Chad D. Richardson, Philip S. Gipson, David P. Jones, James C. Luchsinger Nov 1995

Extirpation Of A Recently Established Feral Pig Population In Kansas, Chad D. Richardson, Philip S. Gipson, David P. Jones, James C. Luchsinger

Eastern Wildlife Damage Management Conference: 7th (1995)

Most feral pigs (Sus scrofa) are descendants of domestic swine that have gone wild and their reproduction is uncontrolled by man. A few populations may be descendants of European wild boar or crosses between wild boar and domestic swine. Disease control officials report that 23 states have established populations of feral pigs and the total feral pig population in the United States is probably in excess of 2 million animals. A population of feral pigs was documented in the fall of 1993 on the Fort Riley Military Installation in northeastern Kansas. Biologists from the Fort Riley Natural Resources …

Can Predator Trapping Improve Waterfowl Recruitment In The Prairie Pothole Region?, Frank C. Rohwer, Pamela R. Garrettson, Ben J. Mense

Eastern Wildlife Damage Management Conference: 7th (1995)

We contrasted nest success for control areas and experimental areas in eastern North Dakota where we employed professionals to trap mammalian nest predators from late March to late July. In 1995, dabbling ducks averaged 53% nest success on four treatment blocks of 4,150 ha each; whereas on four control areas upland nesting ducks averaged 24% success. Diving duck nest success averaged 57% on experimental areas and 29% on control areas. American coot (Fulica americana) nest success also improved on experimental areas, but blackbird nesting and fledging success were not affected by the treatment. In 1994, nest success of …

Black Bear Damage In The Mississippi Alluvial Valley, Thomas H. White Jr., Catherine C. Shropshire, Mike Staten

Eastern Wildlife Damage Management Conference: 7th (1995)

We surveyed 62 hunting clubs in the batture of the Mississippi River in Arkansas and Mississippi to determine the extent and severity of black bear (Ursus americanus) damage. Bear damage was more prevalent in Arkansas (70.6%) than in Mississippi (11.8%). Damage to deer- stands was most common (43.8%), followed by damage to buildings (22.9%), getting in garbage (12.5%) and damage to wildlife food plots (10.4%). Cost estimates of bear damage averaged approximately $40 per incident over the past 5 years. Most (90.9%) clubs rated bear damage as either a slight nuisance or not important at this time, and …

Black Bear Damage Management In Washington State, Georg J. Ziegltrum, Dale L. Nolte

Eastern Wildlife Damage Management Conference: 7th (1995)

Black bears (Ursus americanus) foraging on trees can be extremely detrimental to the health and economic value of a timber stand. A supplemental feeding program to reduce bear damage is coordinated by the Washington Forest Protection Association's Animal Damage Control Program (ADCP). A brief overview of the ADCP is provided along with a description of bear damage and the supplemental feeding program. Success of the feeding program is demonstrated by an increasing participation and its general acceptance by the public. Timber producers placed over 400 thousand pounds of pellets in 700 feeding stations this past year.

Blackbirds And Starlings Killed At Winter Roosts From Pa-14 Applications, 1974-1992: Implications For Regional Population Management, Richard A. Dolbeer, Donald F. Mott, Jerrold L. Belant

Eastern Wildlife Damage Management Conference: 7th (1995)

The surfactant PA-14, registered with the U.S. Environmental Protection Agency (EPA) in 1973 by the federal Animal Damage Control (ADC) program, was used for 19 years (1974-1992) for lethal control of roosting blackbirds (Icterinae) and European starlings (Sturnus vulgaris) in the United States. In 1992, the ADC program withdrew the registration of PA-14 because of costs required to provide additional EPA-requested data. There were 83 roosts encompassing 178 ha treated with 33,300 L of PA-14 from 1974-1992. An estimated 38.2 million birds (48% common grackles [Quiscalus quiscula], 30% European starlings, 13% red-winged blackbirds [Agelaius phoeniceus …

Faculty Publications

Multifragmentation for 129Xe-induced reactions on several targets (natCu, 89Y, 165Ho, 197Au) has been studied at . The probability of emitting n intermediate mass fragments is shown to be binomial at each transversal energy and reducible to an elementary binary probability p. For each target and at each bombarding energy, p shows a thermal behavior as demonstrated by linear Arrhenius plots. A nearly universal linear Arrhenius plot is observed at each bombarding energy, independent of target. The sensitivity of p to the Zthreshold points to its physical significance and rules out auto-correlation effects.

A Statistical Derivation Of The Significant-Digit Law, Theodore P. Hill Nov 1995

A Statistical Derivation Of The Significant-Digit Law, Theodore P. Hill

Research Scholars in Residence

The history, empirical evidence and classical explanations of the significant-digit (or Benford's) law are reviewed, followed by a summary of recent invariant-measure characterizations. Then a new statistical derivation of the law in the form of a CLT-like theorem for significant digits is presented. If distributions are selected at random (in any "unbiased" way) and random samples are then taken from each of these distributions, the significant digits of the combines sample will converge to the logarithmic (Benford) distribution. This helps explain and predict the appearance of the significant0digit phenomenon in many different empirical contexts and helps justify its recent application …

Symmetries Of Accola-Maclachlan And Kulkarni Surfaces, Sean A. Broughton, E Bujalance, A F. Costa, J M. Gamboa, G Gromadzki Nov 1995

Symmetries Of Accola-Maclachlan And Kulkarni Surfaces, Sean A. Broughton, E Bujalance, A F. Costa, J M. Gamboa, G Gromadzki

Mathematical Sciences Technical Reports (MSTR)

For all g greater than or equal to 2, there is a Riemann surface of genus g whose automorphism group has order 8g+8, establishing a lower bound for the possible orders of automorphism groups of Riemann surfaces. Accola and MacLachlan established the existence of such surfaces; we shall call them Accola-MacLachlan surfaces. In this paper we determine the symmetries of surfaces with genus g = 3(mod 4), computing the number of ovals and the separability of the symmetries. The results are then applied to classify the real forms of these complex algebraic curves.

Tailoring Of The Magnetic Properties Of Smco5:Nb0.33Cr0.67 Nanocomposites Using Mechanical Alloying, Richard L. Schalek, Diandra Leslie-Pelecky, John Knight, David J. Sellmyer, Steven C. Axtell Nov 1995

Tailoring Of The Magnetic Properties Of Smco5:Nb0.33Cr0.67 Nanocomposites Using Mechanical Alloying, Richard L. Schalek, Diandra Leslie-Pelecky, John Knight, David J. Sellmyer, Steven C. Axtell

David Sellmyer Publications

Nanocomposite structures composed of ferromagnetic particles dispersed in a matrix are systems in which the magnetic properties can be tailored by varying the size and spacing of the ferromagnetic particles. Nanocomposites of SmCo5 in a non-magnetic Nb0.33Cr0.67 matrix exhibit a wide variety of magnetic properties. SmCo5 powder is premilled prior to mechanical alloying. The premilliing results in a maximum coercivity of 16 kOe after 2 hours of milling, and an enhanced remanence ratio. Both features may be due to exchange anisotropy and/or exchange coupling between hard and soft ferromagnetic phases. The nanocomposite samples show that, …
