Nuisance Bats: Current Technology In Their Management And Control, Robert L. Corrigan

Vertebrate Pest Conference Proceedings: 11th (1984)

Managing nuisance bat colonies can be accomplished via exclusion (bat-proofing) or in limited cases via the use of repellents. Exclusion is emphasized as the first and most desirable approach providing it is also practical. New products and devices have recently become available which may significantly aid in making exclusion programs more possible and practical. Repellents such as lights, fiberglass batting and various improvised mechanical devices may all have some utilization. Controlling nuisance bats can be accomplished via the use of toxicants and trapping, although there is considerable opposition from many bat researchers towards the use of toxicants. Toxicants that have …

Woodpeckers: A Serious Suburban Problem?, Scott R. Craven

Vertebrate Pest Conference Proceedings: 11th (1984)

Damage to homes and buildings caused by woodpeckers is a widespread and locally severe problem in vertebrate pest control. This paper describes the distribution, characteristics, and impacts of woodpecker damage as determined by questionnaires, interviews, and published accounts. Woodpecker damage results from territorial behavior, feeding, or nesting activity. Some plywood and cedar are especially vulnerable. Average loss per incident is about $300, although some cases result in much greater losses. Disturbance and aggravation are also important factors. Abatement measures include scare devices, structural modification, chemical treatment of the siding, and shooting or trapping (with a permit). Success is variable. Recommendations …

Keynote Address—Politics Of Pesticides, David H. Dietz

Vertebrate Pest Conference Proceedings: 11th (1984)

The politics of pesticides is a rather humorless topic, as I'm sure most of you know. I've always been told that when you start an address or make a speech you ought to have some kind of humor, if for no other reason that you at least get your audience to listen to you for two minutes during any presen-tation. For those of you that may be members of the Audubon Society or members of the Sierra Club, I'll, in advance, make my apologies for the joke I'm about to tell. It's not really meant as a put down if …

Rat Control In Alberta, Michael J. Dorrance

Vertebrate Pest Conference Proceedings: 11th (1984)

A rat control program, administered and coordinated by Alberta Department of Agriculture, has kept Alberta essentially free of Norway rats (Rattus norvegicus) since 1950. A control zone, 29 x 600 km, along the eastern border prevents rats from moving into Alberta from the east. Sporadic rat infestations within the interior of Alberta are reported by concerned citizens and eradicated by government personnel. Strong support for the program by citizens and local governments was developed through public education and information. The program has been successful for a variety of reasons including geography, climate, legislation, availability of warfarin, the relatively …

Wetlands And Coal Surface Mining: A Management Handbook, Milady A. Cardamone, Jan R. Taylor, William J. Mitsch

KWRRI Research Reports

As the third phase of a three-year project, this report outlines management options for protecting wetlands during the surface mining of coal, particularly for the portion of the Eastern Interior Coal Region that is found in Kentucky, Indiana, and Illinois. It is presented in manual form for use by coal mine operators, regulatory agencies and research institutions.

The previous phases of the project produced an atlas of the most heavily-mined areas of the western Kentucky coal field, which classified and identified wetlands in these areas, and discussed some specific impacts of mining on these wetlands. The need to present information …

Seasonal And Spatial Heterogeneity In The Limnetic Zooplankton Community Of Lake Mead, Gene Robert Wilde

Publications (WR)

Zooplankton samples collected from throughout Lake Mead, in 1981-1982, demonstrate the presence of a statistically significant seasonal and spatial heterogeneity in zooplankton densities. Seasonally, the major zooplankton groups were most abundant in the spring and fall, coincident with maxima in chlorophyll-a concentrations. Successions among the various rotifers, cladocerans and copepods present in the reservoir were influenced by food availability, diapause, predation by planktivorous fish and, possibly, water temperatures.

Spatial heterogeneity in zooplankton densities was unrelated to water temperature, pH, conductivity and dissolved oxygen concentrations, but was related to the abundance of phytoplankton (chlorophyll-a concentrations) and fish. Statistical analyses indicate that …

The Role Of Nannoplankton In The Phytoplankton Dynamics Of Four Colorado River Reservoirs (Lakes Powell, Mead, Mohave, And Havasu), Jeffrey John Janik

Publications (WR)

Phytoplankton species composition and community size structure were studied in four warm-monomictic Colorado River reservoirs; lakes Powell, Mead, Mohave, and Havasu from March 1981 to February 1982. Sampling was done at approximately monthly intervals from several stations in each reservoir. The Utermohl technique was used to enumerate phytoplankton. The phytoplankton assemblage was divided into the following six size classes using microscopic techniques; netplankton (>64 um), and nannoplankton (>5, 5-11, 12-21, 22-44, and 45-64 um).

Total phytoplankton biomass and community size structure were different among these four reservoirs with considerable spatial and temporal variation present. Average reservoir-wide areal weighted …

A Bacteriological And Chemical Analysis Of Nonpoint Source Pollution In A Karst Aquifer Bowling Green, Kentucky, Wayne Green

Masters Theses & Specialist Projects

Monthly water samples collected from four sites in the Lost River Groundwater Basin, a shallow karst aquifer in the Bowling Green-Warren County area of Kentucky, represented samples from sites receiving conduit and diffuse flow. All sites were severely contaminated with bacteria, and on some occasions the surface water criteria for some heavy metals were exceeded.

Of the total 334 bacterial colonies identified 92.1% were verified as Escherichia coli by the API20E system. Acinetobacter calcoaceticus var. anitratum accounted for 2.10% of colonies; Citrobacter freundii for 0.30% Klebsiella pneumoniae for 0.90%; Klebsiella oxytoca, 0.90%; Citrobacter amalonaticus 0.30%; Enterobacter cloacae, 1.20%; …

Bird Damage Chronology And Feeding Behavior In Two Sunflower Fields, Sacramento, California, 1982, Michael L. Avery, Richard Dehaven

Vertebrate Pest Conference Proceedings: 11th (1984)

Bird damage was assessed weekly from soon after anthesis until harvest in two sunflower fields in the Sacramento Valley, California, during 1982. Damage chronology was similar at both sites, with damage concentrated in the second to fourth weeks after anthesis when the seeds were in the doughy stage of development. Less than 10% of the total losses caused by birds occurred during the final month before harvest. Overall bird damage was quite low (0.20 and 0.26%) in each field and in one, damage by wind was 2.4 times greater than that caused by birds. Brewer's blackbirds (Euphagus cyanocephalus) …

Current Status Of Research On The Blackbird-Sunflower Problem In North Dakota, Joseph L. Guarino

Vertebrate Pest Conference Proceedings: 11th (1984)

Since 1979, the Denver Wildlife Research Center, U.S. Fish and Wildlife Service, has conducted an accelerated research program on the blackbird-sunflower problem which occurs annually in the Dakotas and Minnesota. The objective is to develop effective, cost beneficial and environmentally safe methods for reducing blackbird damage to ripening sunflower. A multidisciplinary approach involving interrelated studies of problem definition, ecology, and control methods development is being used. Preliminary results are presented from several studies involving: state- and county-wide estimates of damage; frequency distribution and timing of damage; compensatory growth in early damaged sunflower heads; breeding male blackbird censuses; mass-marking migratory red-winged …

Biological Rationale For 1080 As A Predacide, Walter E. Howard, Robert H. Schmidt

Vertebrate Pest Conference Proceedings: 11th (1984)

Compound 1080 (sodium monofluoroacetate) is a uniquely selective predacide for controlling coyotes, compared to other predacides. In addition to discussing the biological aspects of 1080, the reasons for the current emotional-political status of 1080 are also reviewed because the biological rationale concerning 1080 has been largely determined by a conspiracy orchestrated in 1972 by an individual of the Council on Environmental Quality but assisted by others from the U.S. Department of the Interior and the Environmental Protection Agency. Many of the distortions about 1080 can also be traced to environmental organizations which still use 1080 as an issue which they …

Strobe Light And Siren Devices For Protecting Fenced-Pasture And Range Sheep From Coyote Predation, Samuel B. Linhart

Vertebrate Pest Conference Proceedings: 11th (1984)

The effectiveness of frightening devices for reducing coyote predation on domestic sheep has not been adequately studied. Portable, battery-operated strobe light/siren devices protected pastured sheep from coyotes for a mean of 53 nights (10 trials) and 91 nights (5 trials). Results of ongoing tests of the devices for reducing predation on herded sheep on summer range in western Colorado have so far been encouraging. Future research needs are outlined.
