Red Swamp Crayfish Ecology In Lake Mead, Suzanne E. Leavitt, Jennifer Stephens Haley, Mikell Hager, Donald H. Baepler, Nevada Department Of Wildlife Mar 1989

Red Swamp Crayfish Ecology In Lake Mead, Suzanne E. Leavitt, Jennifer Stephens Haley, Mikell Hager, Donald H. Baepler, Nevada Department Of Wildlife

Publications (WR)

Red swamp crayfish (Procambarus clarkii) were trapped in Flamingo Wash, an urban wash of Las Vegas, during four periods of 1988. Life history and reproductive success were determined. The trapped crayfish were marked and released into a study cove in Lake Mead as part of an experimental stocking program. Retrap data from the study cove were used to determine life history, habitat preferences, and movement patterns of the stocked crayfish. In addition, a literature search was done on red swamp crayfish ecology, including food preferences, life history, habitat preferences and fish predation.


Design And Statistical Analysis Of Plant Protection Experiment, J F. Wallace Mar 1989

Design And Statistical Analysis Of Plant Protection Experiment, J F. Wallace

All other publications

An Australian co-operation with the national agricultural research project Thailand.

This short course is intended to cover aspects of experimental design, sampling and statistical analysis for researchers in Entomology and Plant Pathology.

The basic principles of experimental design are the same for plant protection research as they are in other areas of research. Problems in plant protection arise from the variation of the data, the complexity of the systems and interactions with environmental factors. In many cases, standard designs are quite adequate.

Use Of Monofilament Line, Reflective Tape, Beach-Balls, And Pyrotechnics For Controlling Grackle Damage To Citrus, Alan R. Tipton, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Dave Johnson, John Hobbs, Paul Schulz, Sam Beasom, Joe Palacios

Great Plains Wildlife Damage Control Workshop Proceedings

The effectiveness of monofilament line, reflective tape, beach-balls and pyrotechnics (propane cannons and shotgun scare shells) in reducing damage to citrus by great-tailed grackles was tested in the lower Rio Grande Valley of southern Texas. Results indicate that these treatments can produce reduction in damage. Whether the treatments are economically advisable for a grower depends on the history of grackle damage to the grove and grove size. Only large amounts of damage in large groves justify costs associated with implementation of these methods.


Fall Food Habits Of Double-Crested Cormorants In Arkansas, Albert E. Bivings, Michael D. Hoy, Jeffrey W. Jones Feb 1989

Fall Food Habits Of Double-Crested Cormorants In Arkansas, Albert E. Bivings, Michael D. Hoy, Jeffrey W. Jones

Great Plains Wildlife Damage Control Workshop Proceedings

One hundred forty-eight double-crested cormorants (Phalacrocorax auritus) were collected in October-December 1988. Some were collected while actively feeding, but most were collected at loafing or roosting areas. Of the 135 with fish in them, 79% contained gizzard shad (Dorosoma cepedianum) and 16% contained centrarchids (mostly Lepomus sp.). The rest contained a variety of aquaculture (commercially raised) fish. Fish prey weights were estimated from total length of prey items and use of published length-weight tables. Total weights of prey ranged from 39 to 4558 with a mean of 185g. This was felt to be a conservative estimate …


Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans Feb 1989

Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans

Great Plains Wildlife Damage Control Workshop Proceedings

We compared the potential of Alpha-chloralose (A-C) and DRC-1339 to reduce a nesting population of herring gulls at an industrial site in Ohio in 1988. Almost all treated baits were consumed by gulls but only about one affected gull was noted for every 10 baits consumed of either chemical. A test indicated our DRC-1339 baits. containing 3.7 - 7.4 times the published LD value, were not lethal to most captive herring gulls living in fresh water. LD values of A-C and DRC-1339 need to be more precisely estimated for gull species in fresh and salt water environments.


Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson Feb 1989

Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson

Great Plains Wildlife Damage Control Workshop Proceedings

In Kansas prairie dog management is primarily determined by private individuals and local government agencies. We conducted a mail survey of 350 affected landowners as a means to evaluate the effectiveness of current prairie dog control. The same survey was also sent to 350 randomly selected state residents within the general prairie dog range. We evaluated people's perceptions of prairie dogs, the effectiveness of control methods, costs of control, and reasons for poor response to control techniques. Results indicate people that have previously been involved in prairie dog control on lands they manage have different opinions about prairie dogs than …


Trophy Game Animal Damage In Wyoming, Ron Iversons Feb 1989

Trophy Game Animal Damage In Wyoming, Ron Iversons

Great Plains Wildlife Damage Control Workshop Proceedings


Wyoming is perhaps one of the most liberal and unique states of the fifty states on compensation for game and trophy game animal damage. Trophy game animals as defined by statute in Wyoming includes the Cougar (Mt. Lion), Black Bear, and the Grizzly Bear. According to statute Wyoming is responsible for damages incurred by these species to livestock, land, crops, improvements, and extraordinary grasses. Since the statutes were enacted Wyoming has been faced with a variety of complaints and damage claims caused by these species. Damage complaints received by the Department have covered a broad spectrum, ranging from the stockman …


Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores Feb 1989

Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores

Great Plains Wildlife Damage Control Workshop Proceedings

Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning dove, white-winged dove, and great-tailed grackle in significant numbers. Nesting success was not reduced significantly by any treatment but observations indicate that cannon treatments are likely to have a negative impact on overall nesting success for several species.

Great Plains Wildlife Damage Control Workshop Proceedings

The Animal Damage Control Unit (ADC) and the 10 other units of the Animal and Plant Health Inspection Service (APHIS) have undergone major reorganization. Emphasis is placed on planning and risk analysis. Four levels of planning have been identified: (1) strategic planning for the Agency, (2) strategic planning for each of the 11 units, (3) program design and risk analysis, and (4) operational planning.


Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios Feb 1989

Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios

Great Plains Wildlife Damage Control Workshop Proceedings

Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …


Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway Feb 1989

Urban Nuisance Wildlife Problems In Arizona, Rebecca L. Wright, Leonard L. Ordway

Great Plains Wildlife Damage Control Workshop Proceedings

Arizona has experienced an increase in urbanization of wildlife habitat, which has led to an urban nuisance wildlife problem. The Arizona Game and Fish Department is working to lessen the problem through public education, information packets and use of private pest control companies to remove wildlife for a fee.


Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth Feb 1989

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth

Great Plains Wildlife Damage Control Workshop Proceedings

Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …


Fisheries Management Paper No.23 - Management Of The South-West Inshore Trawl Fishery., N. Moore Feb 1989

Fisheries Management Paper No.23 - Management Of The South-West Inshore Trawl Fishery., N. Moore

Fisheries Management Papers

This report outlines the management plan for the south west inshore trawl fishery which already operates in coastal waters less than 200 metres deep between Guilderton and Cape Leeuwin.

This management plan takes into account these important concerns and has specifically set aside a strip of coastal area from Cape Bouvard to Cape Leeuwin for recreational usage and for protection of the benthic community, and closed the management zone north of Burns Beach to trawling.

Environmental Assessment In Bioethanol Technology Using Immobilized Yeast Cells, Minoo Kandy Zarnegar Jan 1989

Environmental Assessment In Bioethanol Technology Using Immobilized Yeast Cells, Minoo Kandy Zarnegar

Theses

This study is undertaken from the standpoint of water pollution evaluation in bioethanol technology, using immobilized yeast cells. Evaluation of water pollution caused by immobilized yeast fermentation is the main objective of this research.

The pollution in water remaining at the end of ethanol production, which is normally discharged in the wastewater stream, has been analyzed by the measurement of biological oxygen demand (BOD), since BOD measurement is one of the widely used parameters for water pollution evaluation. BOD obtained from produced water (stillage) was between the range of 115- 360 mg/l. The variation in BOD depended upon the removal …


The 157 Nm Photodissociation Of Ocs, C. E. Strauss, George C. Mcbane, P. L. Houston, I. Burak, J. W. Hepburn Jan 1989

The 157 Nm Photodissociation Of Ocs, C. E. Strauss, George C. Mcbane, P. L. Houston, I. Burak, J. W. Hepburn

Peer Reviewed Articles

The photodissociation of OCS at 157 nm has been investigated by using tunable vacuum ultraviolet radiation to probe the CO and S photoproducts. Sulfur is produced almost entirely in the 1S state, while CO is produced in its ground electronic state and in vibrational levels from v=0-3 in the appropriate ratio (v=0):(v=1):(v=2):(v=3) = (1.0):(1.0):(0.5):(0.3). The rotational distribution for each vibrational level is found to be near Boltzmann, with temperatures that decrease from 1350 K for v=0 to 780 K for v=3. Measurements of the CO Doppler profiles demonstrate that the dissociation takes place from …


The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer Jan 1989

The Use Of Banding Recovery Data To Estimate Dispersal Rates And Gene Flow In Avian Species: Case Studies In The Red-Winged Blackbird And Common Grackle , William S. Moore, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Dispersal resulting in gene flow strongly affects the evolution of genetic structure in populations. This report describes statistical estimators of dispersal parameters based on USFWS banding recovery records. Finite-area studies of avian species yield estimates of root-mean-square (RMS) dispersal along a transect of about 1 km per generation. In contrast, estimates of RMS dispersal for the Red-winged Blackbird (Agelaiusp hoeniceus) and Common Grackle (Ouiscalus auiscula), based on USFWS banding recovery records, are 94.6 and 111.4 km per generation, respectively. Distributions for both species are extremely leptokurtic, and confidence intervals based on jackknife statistics are large because the estimators are sensitive …


An Analysis Of The Factors Influencing Eutrophication Within The China Lake Watershed, Student Collective Organized Against Lake Eutrophication, Colby College, Problems In Environmental Science Course (Biology 493), Colby College Jan 1989

An Analysis Of The Factors Influencing Eutrophication Within The China Lake Watershed, Student Collective Organized Against Lake Eutrophication, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: China Lake (2005, 1989)

Lake eutrophication is the natural process of aging in the lake body with establishment and multiplication of organism over time. The sediment and decaying matter accumulate, gradually filling in the lake basin, transforming the lake from a deep lake to dry land. This process affects the physical make-up of the lake as well as the ecological and biological composition. Eutrophication usually takes thousands of years. However, human interference has greatly accelerated the process by increasing rates of sedimentation and phosphorus loading. China lake has undergone accelerated eutrophication in recent years causing a growing concern for water quality. Algal populations, stimulated …


Assessment Of Squirrel-Caused Power Outages, J. Chris Hamilton, Ron J. Johnson, Ronald M. Case, Michael W. Riley Jan 1989

Assessment Of Squirrel-Caused Power Outages, J. Chris Hamilton, Ron J. Johnson, Ronald M. Case, Michael W. Riley

School of Natural Resources: Faculty Publications

Squirrel-caused power outages in Lincoln and Omaha, Nebraska, were evaluated by examining company power outage reports and by consulting with power company representatives. Reports showed that squirrel-caused outages at pole-mounted transformers were most prevalent during May, June, and October (48% of total) and between 1 and 4 h after sunrise (38%), patterns that coincide with squirrel dispersal or morning activity periods. In Lincoln, 1980 and 1981, squirrels caused 177 outages per year, which was 24% of all outages and 90% of animal-caused outages. Estimated minimum annual costs were $23 364 for repairs, public relations, and lost revenue while meters were …


Track “Core” Effects In Heavy Ion Radiolysis, Robert Katz, Guo-Rong Huang Jan 1989

Track “Core” Effects In Heavy Ion Radiolysis, Robert Katz, Guo-Rong Huang

Robert Katz Publications

By assuming that HO2● radical production in water and H2 production in benzene are 2 hit processes, and applying the concepts of track physics, we are able to obtain a parametric fit to the yields of these reactions by heavy ion radiolysis from knowledge of the radial dose distribution about a heavy ion’s path. We make no use of the concept of a track core, for no clearly definable track core appears in our calculations of the radial dose distribution. Instead we calculate an action cross section σ from the assumed 2 hit response to γ-rays. The …


Water Quality In Southeastern Minnesota Streams: Observations Along A Gradient Of Land Use And Geology, Nels H. Troelstrup Jr., James A. Perry Jan 1989

Water Quality In Southeastern Minnesota Streams: Observations Along A Gradient Of Land Use And Geology, Nels H. Troelstrup Jr., James A. Perry

Journal of the Minnesota Academy of Science

ABSTRACT-Surface water quality in southeastern Minnesota's driftless area exhibits subregional and local spatial patterns which are highly correlated with subsurface geology and land-use practices. Some variables appear to respond on subregional or watershed scales. Nitrate, specific conductance, alkalinity, and surface water atrazine concentrations were lower in streams originating from the Prairie Du Chien or Jordan sandstone ~quifers of easte:n Fillmore and Houston Counties than those originating from the Galena limestone aquifer m west-central Fillmore County. In addition, the numbers of pollution intolerant and functionally specialized invertebrates in the benthic community were higher in the eastern streams. Gross primary production on …


Origin And Developmental History Of Minnesota Lakes, H. E. Wright Jr. Jan 1989

Origin And Developmental History Of Minnesota Lakes, H. E. Wright Jr.

Journal of the Minnesota Academy of Science

ABSTRACT-Most lakes in Minnesota owe their origin directly or indirectly to glacial deposition or erosion 10,000 to 20,000 years ago. The lakes' shapes have since been modified by waves and currents near the shores and by the deposition of sediment off-shore-principally the sediment produced by growth of algae and other organisms. This sediment is a receptacle for pollen grains blown into the lake from the surrounding vegetation, and the stratigraphic succession of pollen grains records the postglacial vegetational and thus climatic history of the area. The sediment also preserves the fossils of microorganisms that reveal by their chemical composition the …


Nitrogen Management Related To Groundwater Quality In Minnesota, James L. Anderson, Gary L. Malzer, Gyles W. Randall, George W. Rehm Jan 1989

Nitrogen Management Related To Groundwater Quality In Minnesota, James L. Anderson, Gary L. Malzer, Gyles W. Randall, George W. Rehm

Journal of the Minnesota Academy of Science

ABSTRACT-Minnesota ranks fifth in overall fertilizer nitrogen (FN) use. Nitrogen is essential for crop production; however, there are concerns about this use relative to profitability and potential impacts on groundwater. There are many sources and sinks of nitrogen in ecosystems. The impact of agricultural management practices on groundwater requires that all sources and fates be considered before FN rates are determined. Research is underway to evaluate relationships between FN application for continuous com and movement of nitrate through soil profiles. Growers making N management decisions have to be able to evaluate the complex nature of N in the environment when …

Journal of the Minnesota Academy of Science

ABS1RACT-Lak~ Itasca, Minnes~ta is located within one of the more popular state parks. Since the turn of the centmy, loggmg, fire protection, and development within the watershed have put modest pressures on the ecosystem. The presence of the University of Minnesota's Biological and Forestry Station on the lake has encouraged research in this region. Consequently there are numerous research reports and papers which are available _at the station's library. We examined data collected over the past 25 years to see if we could detect changes ~~ the lake. We detected no changes in phytoplankton, macrophyte, zooplankton, or zoobenthos com~urnues, but …


The Water Quality And Management Of Lakes In The Twin Cities Metropolitan Area, Richard A. Osgood, Gary L. Oberts Jan 1989

The Water Quality And Management Of Lakes In The Twin Cities Metropolitan Area, Richard A. Osgood, Gary L. Oberts

Journal of the Minnesota Academy of Science

ABSTRACT-We have detected a slow degradation in the water quality of Twin Cities Metropolitan Area lakes du~ to phospho_rus enrichment. While the water quality of the lakes does not appear to limit most uses, nmsances do exist. We have further discovered that commonly-used watershed treatments such as wetland diversions and ponding, are ineffective ~t reversing or completely mitigating the degradati~n following land development. Th_erefore, we are su~gestmg that lake managers reduce the external loading of phosphorus to the greatest ~oss_1ble extent; then, 1f further water quality improvements are necessary, that measures which treat eutroph1cat1on-related symptoms be considered for the long-term …
