Potential Primary And Secondary Hazards Of Avicides, E.W. Schafer Jr.

Vertebrate Pest Conference Proceedings: 11th (1984)

There are six chemicals or groups of chemicals that are currently registered as avicides that can be used in some or all of the U.S. Most of these chemicals, because of their diverse chemical composition and innate toxicological effects, present somewhat different primary and secondary hazards to avian and mammalian predators and scavengers. Of the chemicals reviewed, all appear to present some degree of primary hazard to non-target birds and mammals; however, PA-14, the Starlicide family of chemicals and fenthion appear to be the least hazardous when used according to use directions. 4-Aminopyridine, endrin and strychnine, because of their high …

A Weather-Resistant Tracking Board, D.S. Shepherd, J.H. Greaves

Vertebrate Pest Conference Proceedings: 11th (1984)

The main practical limitation of tracking boards for the study of small mammals is that the sensitive surface is very vulnerable to damage by rain or dew. A tracking board is described that is easily prepared for use in the field, is resistant to rain and running water, and is sensitive enough to record the footprints of mice. The literature on tracking board techniques is reviewed briefly.

The Use Of Wild Carnivore Serology In Determining Patterns Of Plague Activity In Rodents In California, Charles R. Smith, Bernard C. Nelson, Allan M. Barnes

Vertebrate Pest Conference Proceedings: 11th (1984)

Carnivores obtain plague infection through ingestion of infected rodents or rabbits or via flea bite. Most are resistant to infection, show little or no symptoms, and produce antibodies to Yersinia pestis which may persist for several months. Consequently, carnivores can be used as serological plague sentinels using the specific passive or indirect hemagglutination test in the laboratory. A carnivore serology program for plague detection began in California in 1974. The program is a cooperative effort incorporating state and federal vector-borne disease units and state and federal predator animal control personnel. The program has proven to be an important tool in …

Aldehyde Volatiles For Use As Coyote Attractants, Jerry H. Scrivner, Walter E. Howard, Roy Teranishi

Vertebrate Pest Conference Proceedings: 11th (1984)

This study was designed to evaluate the attractiveness of eight aldehyde volatiles (octanal, nonanal, decanal, undecanal, dodecanal, tridecanal, tetradecanal, and hexadecanal) found in sheep liver extract and coyote (Canis latrans) estrous urine to determine their potential for use as odor attractants in predator control. The odors were presented to captive coyotes at the Hopland Field Station and the length of time coyotes responded to the odors was recorded. Octanal, nonanal, decanal, and undecanal all elicited as much sniffing and rub-rolling as did a known coyote attractant, trimethylammo-nium decanoate (TMAD). Generally male and female coyotes were equally attracted to …

A New Concept In Pocket Gopher Control, Allen D. Tunberg, Walter E. Howard, Rex E. Marsh

Vertebrate Pest Conference Proceedings: 11th (1984)

A new concept in pocket gopher control is advanced which relies on two behavioral traits common to pocket gophers: 1) gophers are quick to invade unoccupied burrow systems when the previous occupant has been killed by a rodenticide; and 2) the invading animal will use existing food stores (i.e., baits) left by the previous gopher. With long-lasting (i.e., durable) baits containing sufficient toxicant, several pocket gophers can be controlled by a single baiting. This new approach assists in improving gopher control, for control is extended beyond the initial baiting results. Pocket gophers missed in the original treatment or gophers invading …

The White-Eyes Eradication Effort In California, Valerie Van Way

Vertebrate Pest Conference Proceedings: 11th (1984)

Upon discovery in 1980 in the San Diego area of a feral population of Indian White-eyes (Zosterops palpebrosa palpebrosa), a prohibited species in California, an eradication program was begun by the California Department of Food and Agriculture (CDFA). Mist-netting and shooting proved to be the most successful of the capture methods explored. After three and one-half seasons of retrieval effort and 330 birds taken, fewer than a dozen birds now have been detected in the wild. Within the remainder of the fiscal year, CDFA is conducting intense survey and retrieval. Whether eradication is feasible and applicable to other …

History And Status Of Predator Control In Texas, Dale A. Wade, Donald W. Hawthorne, Gary L. Nunley, Milton Caroline

Vertebrate Pest Conference Proceedings: 11th (1984)

A historical review of predatory animal damage and the development of the Texas animal damage control (ADC) program is provided, including a discussion of predator species, methods of control and limitations caused by laws, regulations and policies. Recommendations are made for improvements to permit a more comprehensive program with adequate funding, personnel and control methods.

Rodent Control In China, Deng Zhi, Wang Cheng-Xin

Vertebrate Pest Conference Proceedings: 11th (1984)

Rodent pest problems and their control in China are reviewed. Three commensal species, Rattus norvegicus, R. flavipectus and Mus musculus, are important pests both in urban and rural regions. Mus musculus is the most widely distributed species in China. Its population density is cyclic, unique for a commensal species in being found in the arid Xinjiang (Sinkiang) Autonomous Region in Northwest China. In South China, R. losea and Bandicota indica are serious problems in rice and cane fields. Many different genera of field rodents are considered pests to agriculture and/or are reservoirs of rodent-borne diseases. These include Citellus, Marmota, …

Skeletal Extension, Density And Calcification Of The Reef Coral, Montastrea Annularis: St. Croix, U.S. Virgin Islands, Richard E. Dodge, Garrett W. Brass

Marine & Environmental Sciences Faculty Articles

Parameters of the annual and subannual skeletal growth of 61 Montastrea annularis corals, collected at a variety of shallow depth sites on reefs of St. Croix, U.S. Virgin Islands, are determined by X-radiography and scanning densitometry for each year in the 10-year period, 1970–1979. Extension (linear growth) of the coral skeleton is correlated negatively with bulk density (mass per unit volume) and positively with calcification (mass addition). Density and mass are slightly positively correlated. No one parameter, however, is a perfect predictor of another. At least two parameters, from which the third can be calculated, are required for complete description …

Predator Management For Ducks On Waterfowl Production Areas In The Northern Plains, Alan B. Sargeant, Phillip M. Arnold

Vertebrate Pest Conference Proceedings: 11th (1984)

In 1961, Congress initiated the Accelerated Wetland Acquisition Program, which has resulted in purchase of about 2,450 scattered small Waterfowl Production Area (WPA) management units in the Prairie Pothole Region of Minnesota, Montana, North Dakota, and South Dakota. The WPAs are administered by the U.S. Fish and Wildlife Service (FWS); increased duck production is a major management objective. Duck recruitment rates in much of the four-state area are very low because of high predation, especially on nests. Principal predators responsible for the predation are six mammalian carnivores and one rodent. The actions of predators on WPAs, especially in central and …

Acute Rodenticides In The Control Of Rodent Pests In China: A Review, Zuwang Wang

Vertebrate Pest Conference Proceedings: 11th (1984)

In China, the earliest record, "The Book of Song," vividly describes that farmers complained of rodent damage and earnestly hoped rodents did not eat their crops. It will be seen from this that since the spring and autumn period (770-476 B.C.), rats, mice and voles have been among the major problems of China. It is said that there are 400 species of mammals in China and 150 species of them are rodents, of which 25-30 species of rodents are usually considered serious pests. Large amounts of grassland, forests and agricultural crops are destroyed or seriously damaged every year. There is …

Las Vegas Wash Multispectral Scanner Survey, T. H. Mace, M. V. Olsen, Environmental Protection Agency

Publications (WR)

At the request of the U.S. Bureau of Reclamation, Boulder City, Nevada, the U.S. Environmental Protection Agency's Environmental Monitoring Systems Laboratory at Las Vegas collected multispectral scanner imagery of Las Vegas Wash on October 1, 1982. A combined maximum likelihood classification and editing procedure was used to classify the multispectral scanner imagery into 12 categories of land cover. The classification identified four categories of marsh vegetation, one category of riparian, two categories of mixed scrub, and two desert categories. Turbid water and cultivated land formed an "other" category. Area tabulations were formed by georeferencing the classification to the Universal Transverse …

Urban Lead In Minnesota: Soil Transect Results Of Four Cities, Howard W. Mielke, Sara Burroughs, Randall Wade, Timothy Yarrow, Paul W. Mielke

Journal of the Minnesota Academy of Science

The focus of this field study was the development of a soil collection and analysis method for the rapid assessment of urban lead (Pb) buildup in four Minnesota cities, Minneapolis, St. Paul, Duluth, and Rochester. The results show that soil Pb buildup is mainly a function of urban size, although specific geographic factors, such as a bluff that constrains city development along a narrow corridor, also play a role in Pb distribution and concentration. Maximum urban Pb concentrations were approximately 25, 70, and 100 times rural soil Pb levels, in Rochester, Duluth, and the centers of Minneapolis and St. Paul …

The National And International Legal Complications Of Subseabed Emplacement Of High-Level Nuclear Waste, Lynn Carlson

Marine Affairs Theses and Major Papers

High-level radioactive waste produced by nuclear power generation, weapons production, and medical research has been accumulating in temporary storage pools in many countries. A permanent method of disposal will soon benecessary to ensure against contamination of man and the environment. Land-based geologic formations, such as salt domes, are the preferred sites for disposal at this time in the United States. Subseabed emplacement is one option under consideration and the technological aspects of this method are currently being studied. In order to resolve these issues, it is proposed that relevant laws be conditionally amended to legalize subseabed emplacement, but only after …

The Effects Of Regulation On Aquaculture Development, Derek S. Busby

Marine Affairs Theses and Major Papers

A comparative study of the regulatory frameworks surrounding aquaculture in the states of Florida, Mississippi, and Rhode Island is conducted beginning with a generalized study of basic legal premises of aquaculture-related law common to each state. This is followed by a detailed study of the statutory authority for aquaculture regulation and the agencies which control aquaculture activities in each state. In conjunction with the law analysis an Index of Specialization (ISP) study is conducted for each state to determine a relative ranking of diversity of crop production relative to each state’s overall aquaculture production.

Marine Resources: The Presentation Of A Business Plan, K. Scott Colby

Marine Affairs Theses and Major Papers

The once questionable technology of hatchery production has become routine and, with the recent development of up-welling techniques, is more effective and efficient. The supply of natural shellfish and fishery stocks is on the decline and this trend is expected to continue. Aquaculture has been the solution to this problem in many European countries and the United States is currently attempting to remove domestic obstacles through its National Aquaculture Plan. The proprietor has experience in the production of various marine invertebrates and has designed, built and operated a producing shellfish hatchery. By using a unique up-welling juvenile culture system a …

Effect Of Small Aspen Clearcuts On Water Yield And Water Quality, United States Department Of Agriculture, Forest Service

Forestry

Streamflow and water quality were monitored in a paired watershed study involving the removal of 20 percent of the aspen (on 13 percent of the area) in five small clearcuts from a 217-acre (88-ha) catchment. There were no significant changes in peak flow, timing, or annual yield during the 4 years of posttreatment monitoring. Significant changes in pH, calcium, magnesium, and nitrates in the snowmelt streamflow from ephemeral subdrainages occurred the second year after cutting. At least some of the differences were attributed to the chemistry of the 1976-77 snowfall, which was also significantly different from snow sampled in the …

Fisheries Report No 63 - Assessment Of Artificial Feeds For Battery Culture Of A Freshwater Crayfish, Marron (Cherax Tenuimanus) (Decapoda: Parastacidae), Dr N. Morrissy

Fisheries Research Reports

Performance of juvenile crayfish, 0.1-5 g, on a variety of commercial crustacean feeds was tested under conditions of individual housing ("battery culture"), where sources of additional feed were minimized (detritus), or eliminated (cannibalism) Survival was close, or equal, to 100% over 50 day test periods, a reflection of optimal battery conditions rather than feeding, since survival over 100 days for an unfed (control} group was also 100%. No ecdysiad mortality, or trauma, occurred with crayfish, up to 10g, in compartments of area 75 cm. Growth performance in tests was rated by separate ratios for ecdysial increment and frequency, relative to …

Effects Of Basis Set And Electron Correlation On The Calculated Properties Of The Ammonia Dimer, Z. Latajka, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

Ab initio calculations are carried out for (NH₃)₂ with a 6‐31G∗∗(1p,2d) basis set containing diffuse polarization functions. Electron correlation is included via second‐order Møller–Plesset perturbation theory (MP2). At the SCF level, the equilibrium R(NN) distance is 3.54 Å and the interaction energy is −2.35 kcal/mol. Inclusion of correlation enhances the attraction substantially, increasing the energy to −4.05 kcal/mol and reducing the intermolecular separation by 0.20 Å. Comparison with previous results at the SCF level demonstrates a variety of errors including exaggerated dipole moments, underestimation of polarization …

Studies Of Dispersion Energy In Hydrogen‐Bonded Systems. H2o–Hoh, H2o–Hf, H3n–Hf, Hf–Hf, M. M. Szczesniak, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

Dispersion energy is calculated in the systems H₂O–HOH, H₂O–HF, H₃N–HF, and HF–HF as a function of the intermolecular separation using a variety of methods. M≂ller–Plesset perturbation theory to second and third orders is applied in conjunction with polarized basis sets of 6‐311G∗∗ type and with an extended basis set including a second set of polarization functions (DZ+2P). These results are compared to a multipole expansion of the dispersion energy, based on the Unsöld approximation, carried out to the inverse tenth power of the intermolecular distance. Pairwise evaluation is also carried out using both atom–atom …
