Control Of One Native Animal Species To Benefit Another Native Species, John T. Lokemoen

Great Plains Wildlife Damage Control Workshop Proceedings

This paper expresses my feelings on the topic of controlling one native animal species (small carnivores) for the benefit of another native species (waterfowl). The relationship between the predator and prey has always been an interesting one. During much of man's experience with wildlife, predators were generally feared and persecuted. It was almost universally agreed that killing predators resulted in larger game populations, which man wanted for food or sport.

A Field Habitat Model For Black-Footed Ferrets, Brian J. Miller, George E. Menkens Jr., Stanley H. Anderson

Great Plains Wildlife Damage Control Workshop Proceedings

We present a model to compare prairie dog complexes with known black-footed ferret habitat. The model assumes: 1) black-footed ferret populations require prairie dog colonies for survival, 2) prairie dog colonies can accommodate an additional black-footed ferret for each approximate 50 hectare increase in size, 3) a higher percentage of overall area covered by prairie dogs can accommodate more black-footed ferrets. We list four biological variables. They are: 1) total hectares in prairie dog colonies, 2) percent of total complex inhabited by prairie dogs, 3) intercolony distance, 4) an estimate of burrow density per hectare. In addition, two non-biological parameters …

Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg

Great Plains Wildlife Damage Control Workshop Proceedings

Small mammals regarded as "pests" should not be viewed separately from other components in the ecosystem. Small mammals have significant influences on vegetation and soils, exert predatory pressure on other animals, and provide food for predators. Future management efforts should include consideration of these diverse influences.

A Chronology Of Prairie Dog Control Operations And Related Developments In South Dakota, Rew Hanson

Great Plains Wildlife Damage Control Workshop Proceedings

The black-tailed prairie dog is a South Dakota native with a long history of controversy regarding its activities and control. The first organized efforts in prairie dog control date back to 1914 but little information was recorded until 1919 with some county operations and the passing of a rodent control law by the South Dakota Legislature. Nine west river counties reported treating a total of 398,000 acres of prairie dogs in 1920.

Kansas Wildlife Damage Reporting System, Bart L. Hettenbach

Great Plains Wildlife Damage Control Workshop Proceedings

In the past several years Kansas State University's Extension Wildlife Damage Control Program and the Kansas Fish and Game agency have developed a cooperative program for reporting wildlife damage complaints. The paper will present some data collected, describe the usefulness of this data and provide some data interpretation.

White-Tailed Prairie Dog Ecology In Wyoming, George E. Menkens Jr., Brian J. Miller, Stanley H. Anderson

Great Plains Wildlife Damage Control Workshop Proceedings

White-tailed prairie dog populations and habitats were studied on six towns in Wyoming. Habitats and habitat structure varied greatly both within and between towns. Prairie dog populations on each town were found to fluctuate by more than 50% between consecutive years. Prairie dog density was not significantly related to burrow density indicating that burrow density was not a useful predictor of population density.

Field Evaluation Of Olfactory Attractants And Strategies Used To Capture Depredating Coyotes, George E. Graves, Major L. Boddicker

Great Plains Wildlife Damage Control Workshop Proceedings

Forty-five experimental and commercial olfactory attractants (lures) were tested under field conditions over a 30-month period to evaluate attractiveness to coyotes, elicited behaviors, and responses with lethal and simulated lethal coyote capture devices. The top 7 lures evaluated in spring and summer test periods that produced the highest simulated coyote capture rates with trap rings, M-44 heads, and break-away snares were WU 15-20%, Sheep Liver Extract, and (Carman's) Canine Distance Call Lure; (Carman's) Final Touch, Rotten Meat Odor, and TMAD 10%; and Estrous Urine Fractions, respectively.

Duck Nest Success And Predators In North Dakota, South Dakota, And Montana: The Central Flyway Study, Michael A. Johnson, Thomas C. Hinz, Thomas L. Kuck

Great Plains Wildlife Damage Control Workshop Proceedings

Data on duck nest success and the distribution and abundance of nest predators were obtained from nine study areas in North Dakota, South Dakota and Montana. Success rates were extremely low due to predation and duck production over much of the region may be insufficient to maintain populations.

Increasing Waterfowl Production On Points And Islands By Reducing Mammalian Predation, John T. Lokemoen, Richard W. Schnaderbeck, Robert Woodward

Great Plains Wildlife Damage Control Workshop Proceedings

On 12 points, with electric predator barriers, there were 0.84 duck nests per acre with a hatching rate of 60%. On 12 control points, there were 0.23 nests per acre with a hatching rate of 8%. On 9 islands where predators were removed, there were 851 nests in 1986 with 87% nest success. In 1984 and 1985, before predators were controlled, these islands contained 52 nests with 8% nest success. The management cost to produce hatched young on treated points was $7.13 compared with $0.33 for each hatched young on islands.

Relevant Characteristics Of Zinc Phosphide As A Rodenticide, Rex E. Marsh

Great Plains Wildlife Damage Control Workshop Proceedings

Zinc phosphide has a long history of use and remains an important rodenticide for both commensal and select field rodents. A long list of significant characteristics contributes to its relative safety to nontarget species. It is zinc phosphide's relative safeness to humans, most livestock, and nontarget wildlife that has kept it in vogue, A most relevant and highly proclaimed characteristic is its general lack of potential secondary hazard to predators and scavengers. Poor or inconsistent efficacy on certain field rodents is a major shortcoming that can, in part, be compensated for by prebaiting. Zinc phosphide's favorable characteristics support its continued …

Rodenticidal Effects Of Zinc Phosphide And Strychnine Of Nontarget Species, Daniel W. Uresk, Rudy M. King, Anthony D. Apa, Michele S. Deisch, Raymond L. Linder

Great Plains Wildlife Damage Control Workshop Proceedings

When three rodenticide treatments—zinc phosphide (prebaited) and strychnine (both with and without prebait)were evaluated, zinc phosphide was the most effective in reducing active burrows of prairie dogs; but, it also resulted in a reduction in deer mouse densities. One month after treatment, counts of fecal pellets of eastern cottontails were greater on areas treated with strychnine without prebait than on sites treated with zinc phosphide. Eight months after treatment, no differences could be detected among rodenticides for either leporid. Horned lark densities were reduced 61% on sites treated with strychnine only.

Policy And Goals In The Private Sector, Rick Warhurst

Great Plains Wildlife Damage Control Workshop Proceedings

Today I am supposed to talk about policy and goals for predator management and control to enhance waterfowl production in the private sector. The private sector includes a wide array of interests. Each of you probably has a particular opinion. You have already observed some different thinking, some different languages, in reference to predator control from previous panel members. If you extrapolate that over the whole United States population, which would be the private sector, it would include a wide array of interests and thoughts.

Decoying Coyotes With Dogs, Gary J. Rowley, Delyle Rowley

Great Plains Wildlife Damage Control Workshop Proceedings

Decoy dogs, used in conjunction with a predator call or coyote howl, are an effective technique to reduce coyote depredation on domestic sheep ranges during the spring and summer when coyotes are highly territorial and aggressively protect their young and den area. Trained decoy dogs, when chased by coyotes, return to their owner bringing the coyotes into shooting range. The type of dogs used successfully for this work is discussed.

Politics, Prairie Dogs, And The Sportsman, John Sharps

Great Plains Wildlife Damage Control Workshop Proceedings

I would like to speak to you today about potential economic and biological values of prairie dogs. When I refer to prairie dogs throughout my talk, I'm referring only to the prairie dogs on the National Grasslands Systems in western South Dakota. Prairie dogs have great economic potential to sportsmen and the general public and also act as ecosystem regulators to grassland plant and animal communities, and as such, could enhance both potentials if managed differently.

Inactivation Of Dry Enzymes And Viruses By Energetic Heavy Ions, M. P. R. Waligorski, Kim Sun Loh, Robert Katz

Robert Katz Publications

A newly developed corrected formula for the radial distribution of dose (RDD) has been used to calculate cross sections for the inactivation of dry enzymes and viruses by heavy ions ranging from ⁴₂He to ⁴⁰₁₈ Ar of energies ca. 10 MeV/a.m.u., spanning a range of LET of ca. 5–2,000 Me V cm² g^–1. In comparison with earlier “point-target” calculations of Butts and Katz where a linear range-energy relationship for electrons (δ-rays) was used, and with “extended-target” calculations of Zhang, Dunn, and Katz, where a power range-energy law and an “uncorrected” RDD formula …

Predator Management To Increase Duck Nest Success, Harold A. Doty, Anthony J. Rondeau

Great Plains Wildlife Damage Control Workshop Proceedings

Operational programs of seasonal predator management to increase duck production may be economically feasible. Mammalian predators of nesting ducks and their eggs were reduced in numbers on selected areas of west central Minnesota during the nesting seasons 1982-86. Where predators were removed, nest success averaged 30% while nest success on nearby untreated habitat was 10%.

Binding Of Fe2+ By Mammalian Ferritin, Richard B. Frankel, G. C. Papaefthymiou, G. D. Watt

Physics

An average of 140 Fe²⁺ ions bind to mammalian ferritin that has an average core content of 1876 Fe³⁺ ions per molecule. The Fe²⁺ ions enter the protein interior and exchange electrons with the core Fe³⁺ ions. A non-homogeneous model for the iron-containing core of ferritin is proposed.

Plagues Of The House Mouse In South Eastern Australia, Glen Saunders

Vertebrate Pest Conference Proceedings: 12th (1986)

Plagues of the house mouse (Mus musculus) occur at irregular intervals throughout the agricultural regions of south-eastern Australia. This paper discusses these phenomena in terms of their impact on agricultural production, previous attempts to reduce damage and levels of infestation, and associated environmental implications. Consideration is also given to the accurate prediction of mouse plagues and the control strategies which need to be in place if effective management is to become a reality.

Polinices Predation Patterns And Mercenaria Morphology Models, John A. Commito

Environmental Studies Faculty Publications

DeAngelis et al. (1985) have described a model of the evolutionary response of bivalve prey to size-selective naticid snail predation. The model analyzed "the allocation of bivalve energy among reproduction, overall growth in size, and supplementary growth in shell thickness" (p. 818). Using parameter values for Polinices duplicatus as the predator and Mercenaria mercenaria as the prey, the model predicted three optimal strategies for bivalves faced with naticid predation: (1) delayed reproduction with energy diverted into rapid growth in order to reach a size refuge; (2) early reproduction, possibly with some extra shell thickness; and (3) greatly increased shell thickness …

Tuna Fishery In The East Central Atlantic Region: The Feasibility Of Nigeria's Participation, Aderemi Olasupo Abioye

Marine Affairs Theses and Major Papers

Tuna fishery is widely practiced in the east central Atlantic region by many fleets of different nationality. Most of the catch is taken by distant-water fleets. The new Law of the Sea convention, which gives coastal states an exclusive economic zone with outer limit of 200 miles, now allows the coastal states to make the most use of the living resources in their waters. The surplus shall be allocated to other states in the region and those traditionally fishing in the area before. Nigeria with a population of about 100 million people spends substantial foreign exchange annually on the importation …

An Analysis Of The Massachusetts Inshore Lobster Fishery, Peter Robertson Hoar

Marine Affairs Theses and Major Papers

The purpose of this thesis was to explore the limited entry alternative of fishery management by examining the history of a particular limited entry scheme: the Massachusetts inshore commercial lobster fishery license limitation law. A review was made of existing limited entry theory, followed by a description of limited entry programs extant in U.S. fisheries. The legislative and political histories of the Massachusetts lobster fishery limited entry program was then examined. The limited entry law was then analyzed by comparing what actually occurred with what is supposed to occur according to limited entry theory. A quantitative analysis of changes in …

The Exclusive Economic Zone-Considerations For Management With Special Reference To Developing Nations, John G. Catena

Marine Affairs Theses and Major Papers

Having successfully initiated and developed the legal aspects of the Exclusive Economic Zone (EEZ) the challenge which now arises for the developing coastal nations is to implement an ocean management system to more fully realize the potential benefits of extended jurisdiction. This study discusses the needs and problems developing nations may encounter in developing such a management system and also considers the ways and means to meet these needs and overcome these problems. The study suggests that coastal nations should adopt an integrated three phased ocean policy process consisting of a (1) priority establishment phase (policy formulation) (2) strategic phase …
