Alligator Nuisance Control Program In Texas: Problem And Process, Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson

Great Plains Wildlife Damage Control Workshop Proceedings

Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in 1983 in Texas (Bowman 1983). Similarity of appearance classification acknowledges the biological security of the Texas alligator population and the need for specific harvest controls to ensure that the conservation of similar appearing species is not compromised. As alligator populations recovered, nuisance complaints directed to the Texas Parks and Wildlife Department (T'PWD) accelerated as well. Complaints now number several hundred annually and …

Wildlife In Texas: Marketing Potential And The Significance Of Wildlife Damage, Milo J. Shult

Great Plains Wildlife Damage Control Workshop Proceedings

This is a challenging topic to discuss, and I would first like to review some things which are unique to Texas with respect to wildlife populations. These concern the importance of wildlife from a commodity standpoint Then I would like to delve into some areas which tend to be a little more philosophical and focus on the impacts of total wildlife management, including wildlife damage control. Historically in our nation, wildlife has had ups and downs; there are a number of success stories in terms of management but also some obvious failures. I would like to be positive today concerning …

The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley

Great Plains Wildlife Damage Control Workshop Proceedings

In the early 1900's organized predator control was initiated to remove coyotes and wolves from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920's, many of the inner Edwards Plateau counties were considered to be practically free of coyotes (Canis latrans) and wolves (Canis lupus, Canis rufus). The 1950's found coyotes and wolves extirpated from most of the Edwards Plateau. After a coyote population erruption in the late 1950's, coyotes began to re-establish themselves on the periphery of the Plateau. This encroachment process continued throughout …

Wildlife Damage In Australia: Constructive Contrasts With The United States, Terrell P. Salmon

Great Plains Wildlife Damage Control Workshop Proceedings

There are numerous wildlife damage problems in Australia. The major pests include rabbits (Oryctolagus cuniculus), foxes (Vulpes vulpes), starlings (Sturnus vulgaris), feral cats (Felis catus), donkeys (Equus asinus), goats (Capra hircus), buffalo (Bubalus trutralis), pigs (Sus scrofa), all of which have been introduced. The dingo (Canis familiaris dingo), classified as being a native species by most people, is the primary native animal causing problems, although others, such as kangaroos and several native bird species, are pests in some areas. The Australians spend considerable amounts of money on wildlife damage control research. The people of Western Australia take a regulatory approach …

Livestock Guarding Dogs Protect Domestic Sheep From Coyote Predation In Kansas, William F. Andelt

Great Plains Wildlife Damage Control Workshop Proceedings

Sheep (Ovis aries) producers were surveyed in Kansas to determine the efficacy of livestock guarding dogs (Canis familiaris) for protecting sheep from coyote (Canis latrans) predation. The majority of producers rated their guard dogs' predator control performance as good or excellent, indicating. that the dogs reduced their reliance on other control methods and substantially reduced monetary losses.

Wildlife Damage Control Program Needs Of County Extension Agents In Colorado, William F. Andelt

Great Plains Wildlife Damage Control Workshop Proceedings

County extension agents indicated that pocket gophers, prairie dogs, skunks, and coyotes were the most important of 32 species requiring extension information for their clientele.

Coyote Vulnerability To Several Management Techniques, Frederik F. Knowlton, Lamer A. Windberg, Cram E. Wahlgren

Great Plains Wildlife Damage Control Workshop Proceedings

We appreciate this opportunity to present a brief synopsis of a complex field study recently completed near Laredo, Texas. It provides a preliminary assessment of differences in coyote vulnerability to several management tools At this point, our analyses are incomplete and interpretations are tentative, at best nonetheless, the data provide some insights and a basis for speculations and questions about coyote behavior, population processes, and the logistics of coyote population reduction. This research was sponsored by the U.S. Fish and Wildlife Service (through the Predator Ecology and Behavior Project) and the Caesar Kleberg Wildlife Research Institute, with generous assistance from …

Furbearer Management And The Steel Foothold Trap, Samuel B. Linhart

Great Plains Wildlife Damage Control Workshop Proceedings

The trapping of furbearers, particularly with steel foothold traps, has become more and more controversial. The controversy is significant because the steel trap is considered the most versatile of the various methods available for capturing furbearers (Payne 1980). Whether traps are used to reduce livestock losses by predators or to harvest furs, the controversy has gained the attention and interest of various social factions, each with differing beliefs, attitudes, and philosophies.

The Use Of Population Reduction As A Technique To Combat Rabies In Alberta, Canada, Richard C. Rosatte

Great Plains Wildlife Damage Control Workshop Proceedings

Control of rabies by reducing the density of potential vectors has been a controversial matter. Only 2 outbreaks of rabies in Europe are likely to have been completely eradicated by control, 1 in Dijon, France, in 1923, and the other in Corsica in 1943 (MacDonald 1980). Schnurrenberger et aL (1964) apparently controlled an outbreak of rabies in striped skunks (Mephitis mephitis) in Ohio by gassing dens and through the use of poison. An invasion of red fox (Vulpes vulpesl rabies in southern Jutland from Demark was initially halted by a gassing and poisoning campaign. However, in Great Britian, despite the …

Redox Reaction Kinetics Between Cobalt(Ii)-4,4',4",4'"-Tetrasulfophthalocyanine & Iodine In Various Solvents, Byung-Soo Yu

Masters Theses & Specialist Projects

Analyses of the kinetic data obtained on the redox reaction between cobalt(II)-4,4',4",4"-tetrasulfophthalocyanine [Co(II)TSPC4^-] and iodine in the presence of air show three reactions in dimethylsulfoxide(DMS0), N,N-dimethylacetamide(DMA), and diethylene glycol(DEG) while there are two reactions in methanol(Me0H). Two of the three reactions in DMSO, DMA, and DEG are biphasic with one reaction in all of the solvents being too fast to be accurately measured on the Cary Model 14 spectrophotometer. When the reactant solutions are purged with argon for 40 minutes under identical conditions, the same biphasic reactions are observed in DMSO and DEG while only one of the …

Reductive Dechlorination Of Toxic Chlorocarbons, K. Grant Taylor

KWRRI Research Reports

The sodium hydride based reducing agents were prepared the method of Caubere (Angew. Chem. Int. Ed. Engl., 1983, 22, 599-613). Reagents were prepared containing nickel, iron and zinc metals. All were effective in dechlorinating 1,3-dichlorobenzene, 4-methoxy-chlorobenzene, and arochlor 1254. Most work focused on nickel based reagents, the most active. The nickel-based reducing agent used in THF at 65°C reduced to 200 ppm 1,3-dichlorobenzene (to benzene) and arochlor 1254 (to biphenyl) to below 0.2 ppm in less than 15 minutes. A two stage reduction reduced arochlor 1254 to below a detectable level as determined by gas chromatography using f.i.d. detector. Using …

Mathematical Programming Model Of Western Australian Dairy Farms, G R. Olney, D A. Falconer

Animal production and livestock research reports

A profit maximising mathematical programming dairy farm model has been developed which determines the most profitable management strategies for the full year. This model was initially an extension of the one used in the Western Australian Dairy Feed Management Service (DFMS) which determines the most profitable ration to feed for a specific period, the milk yield per cow and the number of cows to milk. The DFMS is useful for formulating a ration for a specific period, particularly during summer on non-irrigated farms in Western Australia when complete hand feeding is required, but it cannot be used to determine optimum …

Multiple Trophic Levels In Soft-Bottom Communities, John A. Commito, William G. Ambrose Jr.

Environmental Studies Faculty Publications

In order to assess the general applicability of recent field experiments with predatory infauna, we searched the literature and found 48 well-documented cases of infaunal consumption by such predators. In 63 % of the cases detailed enough to make a determination, the predators ate other predators. Multiple trophic levels within the infauna are probably a common feature of many soft-bottom communities.

Western Australia continues to be one of the leading fishing States in Australia. The total gross value of fish, crustaceans and molluscs for 1983/84 was $141 million (Table 1) to which may be added the value of the pearl culture industry resulting in a total value of approximately $160 million.

The Equatorial Pacific High-Productivity Belt: Elements For A Synthesis Of Deep Sea Drilling Project Leg 85 Resultspaleoceanography, Fritz Theyer, Larry A. Mayer, John A. Barron, Ellen Thomas

Affiliate Scholarship

Leg 85 of the Deep Sea Drilling Project operated in the eastern central Pacific in the region of the equatorial highproductivity belt. We recovered uppermost Eocene to Quaternary reference sections amenable to fine-scale stratigraphic and paleoceanographic research, using primarily the hydraulic piston corer. Four sites (572 to 575) were drilled along an east-west (about 114 to 133°W) and north-south (about 0.5 to 6°N) transect across the equatorial belt. At Site 572 an apparently complete lower middle Miocene to Quaternary sequence was recovered: the sediment sections are dominantly siliceous-calcareous oozes and chalks, and sediment accumulation rates were high (30 to 60 …
