Analysis Of Arkansas Fur Harvest Records - 1942-1984: Ii. Species Accounts, James H. Peck, Joseph D. Clark, Tiny Sheldon, Gary A. Heidt

Journal of the Arkansas Academy of Science

Fur harvest records were maintained by the Arkansas Game and Fish Commission on the following 16 furbearers: badger, beaver, bobcat, eastern spotted skunk (civet), coyote, gray fox, long-tailed weasel, mink, muskrat, nutria, opossum, raccoon, red fox, red wolf, river otter, and striped skunk. These harvest records were analyzed for each species in terms of mean pelt price and numbers of pelt sold by region (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta) per year. Historical or biological influences important in interpreting species accounts are presented.

Wildlife Response To Stand Structure Of Green Ash Woodlands, Robert A. Hodorff

Electronic Theses and Dissertations

Vegetation, birds and mammals were sampled over two years in two types of green ash woodlands in extreme northwestern South Dakota. Woodlands referred to as closed canopy stands consisted of dense stands of various species of trees and shrubs in different size and age classes. Woodlands referred to as open canopy stands had sparse stands of older trees, with intermediate seedling, sapling and tall shrub layers nearly absent. Closed stands had significantly greater (P = .002) coverage of shrubs in the understory than open stands while open stands had significantly greater (P = .004) total coverage of grasses than closed …

Evaluation Of Seasonal Habitat Use By White-Tailed Deer In Eastern South Dakota, Thomas James Kramlich

Electronic Theses and Dissertations

Seasonal use of selected habitat types by white-tailed deer (Odocoileus virginianus) was investigated using radio telemetry locations during 1983 and 1984, on a predominantly agricultural area in east-central South Dakota. In the summer of 1983, radio-collared deer used corn, shelterbelts, and wetlands in proportion to their availability. Soybeans, grainfields, and grasslands were avoided. Deer selected shelterbelts in the fall and wetlands during the winter months, for protective cover. Habitat use shifted in the spring and shelterbelts received heavy use, once they became free of drifted snow. Shelterbelts continued to be selected by deer during the summer of 1984. IN the …

Effectiveness Of Shelterbelts In Improving Microclimatic Conditions For Pheasants In Eastern South Dakota, Todd Matthew Schneider

Electronic Theses and Dissertations

To evaluate wintering habitat for ring-necked pheasants (Phasianus colchicus), this study compared microclimate regimes , as determined by wind and temperature, between shelterbelts containing 1 or 2 rows of coniferous tree species with shelterbelts comprised entirely of deciduous tree species and between wetland and shelterbelt habitats. Maximum temperatures within both shelterbelt types, particularly deciduous shelterbelts, were cooler than outside ambient air temperature during summer. Throughout November, December, and January, minimum temperatures in coniferous shelterbelts types were significantly (P≤0.04) warmer than deciduous shelterbelt types. Effectiveness of shelterbelts in reducing wind velocity decreased from an average of 71% during summer to 28% …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Iii. Harvest-Price Relationships, Joseph D. Clark, Gary A. Heidt, Tina Sheldon, James H. Peck

Journal of the Arkansas Academy of Science

Correlation and linear regression analyses between mean annual pelt price and total harvest of 13 Arkansas furbearer species between 1965 and 1983 were performed for state and regions (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta). Statewide, strong correlations (r > 0.80) were identified for bobcat (Felis rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), mink (Mustela vison), nutria (Myocastor coypus), opossum (Didelphis virginiana), and raccoon (Procyonlotor). Moderate correlations (r = 0.55 - 0.79) were identified for eastern spotted skunk (Spilogale putorius), muskrat (Ondatra zibethicus), river otter (Lutra canadensis), and striped skunk (Mephitis mephitis). Nonsignificant correlations (r < 0.468) were shown for beaver (Castor canadensis) and long-tailed weasel (Mustela frenata). Regional differences were noted for each species.

Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige

Electronic Theses and Dissertations

Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: I. State And Regional Accounts, Gary A. Heidt, James H. Peck, Tiny Sheldon, Joseph D. Clark

Journal of the Arkansas Academy of Science

Fur harvest records maintained by the Arkansas Game and Fish Commission from 1942-1984 summarized the number of pelts sold by region (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta) and the average price per pelt for 16 furbearers. Analysis of these records showed that in the 1979-80 trapping season (the record year for both harvest and value both in Arkansas and the nation), the value of the Arkansas fur harvest ranked 14th nationally (2.12% of total national value). Fur harvests in Arkansas were high in the 1940's, declined in the 1950's and 1960's and then experienced a rapid …

Sex-Specific Feeding Habits Of Brown-Headed Cowbirds In Northern Ohio In January, Richard A. Dolbeer, Cynthia R. Smith

United States Department of Agriculture Wildlife Services: Staff Publications

We examined the stomach contents of 57 brown-headed cowbirds (Molothrus ater) collected from a roost in Erie Co., Ohio, on 12 January 1983. Corn was by far the predominant food, averaging 66% of the stomach contents by weight. Seeds from at least five grasses, but primarily Setaria spp., were the second most abundant food category, averaging 21% of the stomach contents. Ragweed {Ambrosia artemisiifolia) seeds (2.6%) were third. Male cowbirds consumed more corn than did the smaller females, whereas females consumed more of the smaller grass seeds. The abundance of corn in harvested fields and feedlots, combined with mild winter …

Fisheries Report No 71 - An Investigation Of The Mortality Of The Pearl Oyster, Pinctada Maxima, In Western Australia, Rand Dybdahl, David A. Pass

Fisheries Research Reports

A three year investigation into the cause of abnormally high mortality rates of the pearl oyster, Pinctada maxima, on the cultured pearl industry's lease sites in the North West of Western Australia was completed on 30 June 71983. The objective of this study was to determine environmental, physiological and pathological factors predisposing farm oysters to excessive Levels of mortality and, if possible, make recommendations to alleviate this problem.

As mass mortalities may have complex causes, complementary field and laboratory studies were instigated. The culture industry's method of collection, transportation and farm husbandry were examined. Environmental parameters were monitored. Various empirical …

A Study Of Trihalomethane Precursors In Deer Creek Reservoir, Megan J. White, V. Dean Adams

Reports

Deer Creek Reservoir and tributaries were monitored from May to December 1983 in a study of the occurrence of trihalomethane (THM) precursors in the reservoir and nutrient dynamics of the reservoir system. Microcosms were used to study the effect of the following parameters on THM precursor production in the reservoir system: phosphorus loading, sediment, algal growth, and application of algicide. Additionally, THM precursor concentrations of interstitial water were analyzed in reservoir and microcosm sediment samples. Microcosms treated with ahigh phosphorus loading (70 ug/1) had THM precursor concentrations significantly higher than those measured in microcosms treated with a low phosphorus loading …

Preliminary Identification, Analysis, And Classification Of Odor-Causing Mechanisms Influenced By Decreasing Salinity Of The Great Salt Lake, C. Earl Israelsen, Darwin L. Sorensen, Alberta J. Seierstad, Charlotte Brennard

Reports

Introduction: The rising level of the Great Salt Lake has received a great deal of attention because of the resulting physical damage to adjoining properties, threatened distruption of major transportation facilities, and environmental damage to feeding and resting areas for migratory waterfowl. Another problem of growing concern is that some zones of the lake are producing odors that are objectionable to nearby populated areas. These odors are most offensive during the warm summer months and appear to be increasing with the rising levels and decreasing salinity of the lake water. This report presents the approach taken and the findings of …

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson

Publications (WR)

Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m³. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m³. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

Success In Rat Control In Kuwait, K.S. Al-Sanei, T.M. Zaghloul, A.M. Salit, M.T. Omar, M.M. Balba

Vertebrate Pest Conference Proceedings: 11th (1984)

The preliminary rat survey prior to the actual attack phase of Rat Control Program in Kuwait revealed an infestation rate with the Norway rat, Rattus norveqicus, in buildings ranging between 32.7% and 70.7%. The comparatively high infestation was observed in 92.5% of Kuwait buildings. Moreover the infestation reached 99% in certain districts of the country. This high infestation was associated with an increase in rat-borne diseases particularly murine typhus, salmonellosis, rat-bite fever and certain parasitic diseases.

A programme for rodent control in Kuwait was initiated through a political decision by the cabinet which gave the full responsibility of rodent …

Hazards To Golden-Mantled Ground Squirrels And Associated Secondary Hazard Potential From Strychnine For Forest Secondary Pocket Gophers, R. Michael Anthony, Gerald D. Lindsey, James Evans

Vertebrate Pest Conference Proceedings: 11th (1984)

Radio telemetry and capture-recapture techniques were used to evaluate the hazards to golden-mantled ground squirrels ( Spermophilus lateralis) from hand baiting with 0.5% strychnine-treated for western pocket gophers (Thomomys mazama) on conifer plantations in eastern Oregon. Toxicology data were collected on field-killed and caged ground squirrels and on caged mink (Mustela vison, great horned owls (Bubo virginianus), and red-tailed hawks (Buteo jamaicensis). Ground squirrel populations were reduced 50% to 75% following underground baiting for pocket gophers. Maximum amount of strychnine found in cheek pouches and carcass of a field-killed golden-mantled ground …

Commingling Of Norway And Roof Rats With Native Rodents, Rex O. Baker

Vertebrate Pest Conference Proceedings: 11th (1984)

The ecology of plague relies on the intermixing (commingling) of animal hosts and their ectoparasites. There has been a noticeable increase in commingling of rats and ground squirrels in Southern California in recent years. This paper discusses this phenomenon in Los Angeles and Orange Counties, where it occurs, how it results from man's activities, and the ecology of varying locations. The role of fleas as vectors of plague and the intermixing of fleas between hosts are discussed. Action to reduce the incidence of commingling and the threat of plague to the urban society is addressed.

Efficacy Of Three Anticoagulant Rodenticides For The Control Of Poison-Shy Rattus Rattus, Devendra Bhardwaj, Ishwar Prakash

Vertebrate Pest Conference Proceedings: 11th (1984)

House rats (Rattus rattus) which do not consume a lethal dose of zinc phosphide develop poison-shyness after a single exposure. The surviving poison-shy rats cannot be baited again with zinc phosphide for about three months. Poison-shy rats were separately given anticoagulant baits (brodifa-coum 0.005%, coumatetralyl and warfarin 0.025%) in no-choice tests. The first two anticoagulants were found to be the most efficient ones. It was observed that those R. rattus which had consumed 56.7 mg/kg or more zinc phosphide died sooner (P < 0.05 to 0.1) after anticoagulant poisoning when compared with normal rats. It is conjectured that prothrombin inhibition is accelerated in the liver of poison-shy R. rattus due to the action of phosphine present in the earlier ingested sublethal dose of …

Repellent Or Aversive Chemicals In Sheep Neck Collars Did Not Deter Coyote Attacks, Richard J. Burns, Guy E. Connolly, Richard E. Griffiths Jr.

Vertebrate Pest Conference Proceedings: 11th (1984)

Since 1974 the Fish and Wildlife Service has studied a "toxic collar" to poison coyotes that attack collared sheep and goats. The collar patent (McBride 1974) indicates that the same collar could deliver chemicals to repel coyotes, thus saving both the coyote and the livestock.

This report summarizes our experience with nonlethal tests of collars. During collar tests with 10 different toxicants, 21 coyotes received sublethal doses followed by aversive behavior or potentially aversive reactions. The subsequent predation history of these coyotes was examined for prey-avoidance. After a sublethal test, all coyotes killed lambs or kids in about 40 days, …

Vole Control In Field Crops, Jerry P. Clark

Vertebrate Pest Conference Proceedings: 11th (1984)

There are five species of meadow voles found in California. The two that are most economically important are Microtus californicus and Microtus montanus. Meadow vole populations are extremely cyclic, reaching a peak every four to six years. During these periods when the vole population is increasing in numbers, damage to crops like alfalfa, artichokes, potatoes, and sugar beets can occur. The best time to survey for vole activity is before the crop is planted. The grower or farm operator should look for vole activity in grassy borders around the crop or along roadsides and ditch bank areas. Snap-trapping may …
