Effects Of Zebra Mussel, Dreissena Polymorpha, Infestation On Lake Dardanelle Water Quality, Charles J. Gagen, Joseph N. Stoeckel

Arkansas Water Resources Center Technical Reports

Zebra mussels recently invaded southern waterways including the Arkansas River. Exponential population growth and high filtration capacity of dense populations could alter reservoir ecosystem function. Furthermore, they attach to hard surfaces; thus, threatening normal operations of many artificial structures. We designed this study to provide baseline data prior to high population levels of zebra mussels in Lake Dardanelle. The characterization of spatial and temporal variability in water quality, zooplankton, phytoplankton, and macrophytes will allow testing of several hypotheses. We sampled zebra mussel density and zooplankton at four fixed sites and the other key variables at three of these sites biweekly …

Assessment Of Effectiveness Of Buffer Zones In Removing Impurities In Runoff From Areas Treated With Poultry Litter. Part Ii: Source Areas To Buffer Areas Ratio Effects, P. Srivastava, D. R. Edards, T. C. Daniel

Arkansas Water Resources Center Technical Reports

Vegetative filter strips (VFS) are known to reduce runoff losses of nutrients. solids. and other materials from land areas treated with fertilizers . Although VFS effectiveness is known to depend partially on the relative lengths of filter and pollutant source areas. there is little experimental evidence available to quantify this dependence. This is particularly the case when VFS are implemented down-slope of pasture areas treated with animal manures such as poultry litter. This study assessed the influences of pollutant source area (treated with poultry litter) and VFS lengths on VFS removal of total Kjeldahl nitrogen (TKN). ammonia nitrogen (NH3 -N …

Analysis Of The Oxidation Of Isotox By Immobilized Bacteria, Chad Sheng

Theses

The purpose of this work is to show the effects of bio-oxidation of a pesticide through a spiral wound bioreactor using immobilized mixed culture bacteria. The pesticide used for this study is Isotox® and its active ingredients are acephate or O,S-dimethyl acetylphosphoramidothioate and vendex or hexakis (2-methyl-2-phenylpropyI)- distannoxane. Qualitative analysis of the product indicated presence of sulfate.

A consistent and unique DO pattern for Isotox^® showed at least 4 minima, whereas phenol has only one minimum. The consistency of the DO pattern for Isotox^® has been observed for over 30 injections into the bioreactor system. For both an …

Whaling Error, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

You published recently (Nature 374, 587; 1995) a report headed "Error re-opens 'scientific' whaling debate".

The error in question, however, relates to commercial whaling, not to scientific whaling. Although Norway cites science as a basis for the way in which it sets its own quota. scientific whaling means something quite different. namely killing whales for research purposes. Any member of the International Whaling Commission (IWC) has the right to conduct a research catch under the International Convention for the Regulation of Whaling. 1946. The IWC has reviewed new research or scientific whaling programs for Japan and Norway since the …

Transitions In Masculinity And Hemingway's Developed "Code", Daniel Polk

Honors Theses

The "Hemingway Code" is much more than two words that fit nicely together for a scholar's usage; the words signify a much deeper championing of masculinity, almost a haunting presence. For Ernest Hemingway living life every day, every moment with its fullest masculine fervor, became an obsession, a never-ending quest to be at one with the attitude of never complaining, never crying out, panicking, thinking too much, or regretting. To live a manly life in a series of tactical victories, performed with steadfast ritualistic mannerisms, is to embody masculinity, and therefore the "Hemingway Code."

Evaluation Of Lake Fertilization As A Tool To Assist In The Recovery Of The Snake River Sockeye Salmon (Oncorhynchus Nerka), Howard P. Gross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I analyzed lake fertilization (with nitrogen and phosphorus) as a tool to assist in the recovery of the Snake River sockeye salmon (Oncorhynchus nerka) in the oligotrophic Sawtooth Valley Lakes in southcentral Idaho. These analyses involved monitoring, manipulating, and modelling several aspects of the lakes' primary producer, nutrient, and light parameters.

In Pettit Lake, I evaluated the effects of metalimnetic and epilimnetic fertilization in 330-m³ mesocosms. The metalimnetic treatment was equal to or more effective than the epilimnetic treatment in increasing chlorophyll a, phytoplankton biovolume, and primary productivity, yet caused smaller changes in periphyton growth and …

Competitive Interactions Between Two Closely Related Rhizomatous And Caespitose Perennial Grasses Under Varying Conditions, L. David Humphrey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biomass, tiller numbers, flowering, and genet survival were accessed for the rhizomatous Elymus lanceolatus ssp. lanceolatus and caespitose E. l. ssp. wawawaiensis growing in mixtures with a range of densities of each taxon. Models of aboveground biomass of each taxon as a function of mixed densities were used to calculate competition indices. Tiller numbers and biomass of ssp. lanceolatus were higher than those of the caespitose taxon in the first year, but declined in the second year, while biomass and tiller numbers of ssp. wawawaiensis changed little. All tillers of ssp. wawawaiensis emerged in autumn; tillers of ssp. …

Behavioral Characteristics Affect Habitat Selection Of Domestic Ruminants, Cody B. Scott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I evaluated some of the factors affecting livestock distribution by conducting experimental (Chapters II and III) and observational (Chapter IV) studies. In Chapter II, I described the effect of locations of familiar foods and social interactions on choice of feeding location by lambs. Lambs were exposed to a pasture as subgroups of strangers and companions with different dietary habits (i.e., three lambs that preferred milo with three lambs that preferred wheat). Milo was placed on one end and wheat on the other, about 100 m apart. Strangers typically fed in different locations, reflecting dietary preferences. Conversely, companions fed in both …

Disease And Habitat Change As Factors Associated With Mourning Dove Population Decline, William D. Ostrand

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The western mourning dove (Zenaida macroura) population has been declining since 1966. Data collected in 1951-52, in Fillmore, Utah, provided us a baseline for comparison with our study in the same area. Our approach was to determine whether a local population decline had occurred since the original data were collected, assess if trichomoniasis has impacted the local population, determine if changes in habitat structure affect foraging site selection, quantify changes in habitat, identify which habitats doves preferred, ascertain whether doves had responded to habitat change by changing food habits, and assess if changes in habitat were responsible in …

Winter Habitat Selection By American Marten (Martes Americana) In Newfoundland: Why Old Growth?, Gary S. Drew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although the American marten (Martes americana) generally is recognized as an obligate late-seral species, the factors dictating this association are poorly understood. Martens were studied in Newfoundland, Yellowstone National Park, and in a captive setting. As expected, use of habitat types was not proportional to availability P < 0.001). Defoliated and late-seral conifer stands were used more than expected, while all other types indicated expected or less than expected use. Habitat selection by martens was detectable at spatial scales greater than 80 m (P < 0.001).

Newfoundland martens were radio-collared and monitored for diet activity during the winters of 1990 and 1991. A regression of the percent active fixes on temperature had a negative slope (b = -4.45, P = 0.084, n = 12), indicating that martens did not minimize their exposure to low temperatures. A log-linear model suggested …

21 pages.

Includes illustrations, maps, and biographical information for Gordon W. Fassett and James S. Lochhead.

Habitat for species listed as endangered under federal law along the Platte River in Nebraska has been adversely affected by decreased river flows, resulting in federal legal barriers to further water development throughout the basin in three states. In June 1994 state and federal officials entered an agreement to develop a basin-wide recovery plan. Elizabeth Rieke, Assistant Secretary for Water & Science, Dept. of Interior, will discuss federal perspectives. Gordon (Jeff) Fassett, Wyoming State Engineer, and J. Michael (Mike) Jess, Nebraska …

Resource Use Conflict In New York City's Catskill Watersheds: A Case For Expanding The Scope Of Water Resource Management, Krystyna Anne Stave

Public Policy and Leadership Faculty Publications

In New York City's water supply watersheds, controversy over water quality protection underscores both the need to expand the scope of water resource management and the challenges to doing so. This paper describes the response of watershed residents to !'Jew York City's efforts to avoid filtration mandated by the 1986 Safe Drinking Water Act Amendments and 1989 Surface Water Treatment Rule. The emergence of a spectrum of stakeholder groups representing land owners, sport fishermen, businesses, environmental groups and local communities has brought social and economic issues not previously part of the City's water management program to the center of the …

A Comparison Of Attitudes Held By Wildlife Damage Managers And Animal Rights Activists, James B. Armstrong, Melissa E. Hutchins

Great Plains Wildlife Damage Control Workshop Proceedings

We designed an instrument to measure attitudes about a variety of animal use issues, collect information on animal-related activities, and determine demographic characteristics of the sample. We administered the instrument to 151 Animal Rights Information and Education Service (ARIES) and 150 National Animal Damage Control Association (N ADC A) members. Based on analysis of the data, we concluded that these 2 groups differ greatly on their attitudes about human use of animals. In addition, they differ greatly in background and types of activities in which they participate. Thus, attempts to bring these groups together for discussion must start with the …

Dynamics Of Wildlife Damage Management, Bobby R. Acord

Great Plains Wildlife Damage Control Workshop Proceedings

Wildlife damage management is a dynamic profession. Our focus has shifted from dealing with primarily agricultural interests. In addition to agricultural issues, we now deal with endangered species protection, human health and safety, and wildlife damage management issues in the urban environment. The dynamics of wildlife damage management are influenced by the changing needs of society, professionalism among our ranks, and the political process. Professionalism and meeting the needs of the public continue to be the most important part of the dynamics of wildlife damage management.

Effective Repellency Concentration Of Bird Shield Repellent(Tm) With Methyl Anthranilate To Exclude Ducks And Geese From Water Impoundments, Leonard R. Askham

Great Plains Wildlife Damage Control Workshop Proceedings

Laboratory studies were conducted to establish the effective repellency concentration (EC_R) of Bird Shield Repellent(^TM) on mallard ducks (Anas platyrhynchos) and domestic geese for fresh water impoundments. Six concentrations of the repellent compound, ranging from 90 ppm to 2,890 ppm, were placed in small ponds in 2 aviaries and bird behavior monitored for 7 days. Concentrations <360 ppm did not limit either of the test species' activities (drinking or bathing) in the impoundments. Concentration >725 ppm precluded most activity after an initial exposure. Dissolved oxygen tended to decrease after an initial rise and pH increased slightly. Impoundments became discolored with higher concentrations of the repellents' methyl anthranilate precipitates in 24 hr.

Effects Of Mule Deer Grazing On Alfalfa Seed Production, Dennis D. Austin, Philip J. Urness

Great Plains Wildlife Damage Control Workshop Proceedings

Evaluation of crop loss caused by mule deer (Odocoileus hemionus) grazing on alfalfa grown for seed harvest was studied in northern Utah. Results indicated (1) wire baskets used to protect non-grazed plots did not affect alfalfa production, and (2) alfalfa seed crop loss was directly correlated with alfalfa hay crop loss. Consequently, methods used to evaluate crop loss to alfalfa hay may be applied to alfalfa seed.

Resolving Human-Large Felid Conflicts Associated With Protected Areas In India, N.P.S. Chauhan, V.B. Sawarkar, H.S. Pabla

Great Plains Wildlife Damage Control Workshop Proceedings

In India, the past 2 decades of improved wildlife management practices along with rigid legal provisions have resulted in increased populations of the endangered carnivores: tiger (Panthera tigris), lion (Panthera leo), and leopard (Panthera pardus) in protected areas (PAs). Over this time period, human and livestock populations in and around PAs have also increased substantially. Intense human use and commensurate cattle grazing activity in associated forests have invariably lead to confrontation with these carnivores. Incidences of human- and cattle-killing by tiger, lion, and leopard have increased in and around PAs. Ongoing conflicts occur with …

Plastic Visual Barriers Were Ineffective At Reducing Recolonization Rates Of Prairie Dogs, Scott E. Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

Two plastic visual barriers were ineffective in controlling expansion of 7 active black-tailed prairie dog (Cynomys ludovicianus) colonies and recolonization of 7 toxicant-treated sections of colonies. Barriers constructed with Sno-Strap, a 15.2- cm wide band of high-tensile polyethylene plastic, were destroyed by wind action within 3 weeks. Barriers constructed with Tensar® snowfence cost $2.10/m and retained their structural integrity for 3 years with occasional maintenance. Recommendations are provided to increase effectiveness of visual barriers.
