A Survey Of Source And Finished Water Supplies For Giardia Cysts And Cryptosporidium Oocysts, Lisa Martin Sexton

KWRRI Research Reports

The occurrence of Giardia lamblia cysts and Cryptosporidium parvum oocysts was determined from source and treated drinking water supplies at selected water treatment facilities in Eastern Kentucky. Giardia and Cryptosporidium are two human protozoan parasites often found in water supplies due to fecal contamination. Characteristic cysts and oocysts were identified from large volume water samples, typically 100 gallons for raw samples and 1,000 gallons for finished water, using an indirect fluorescent antibody specific for Giardia and Cryptosporidium. Source water from four different water treatment facilities utilizing a reservoir, river, and two creeks were assayed. All sites exhibited Giardia lamblia …

Evidence Of Natural Bluetongue Virus Infection Among African Carnivores, Kathleen A. Alexander, N. James Maclachlan, Pieter W. Kat, Carol House, Stephen J. O'Brien, Nicholas W. Lerche, Mary Sawyer, Laurence G. Frank, Kay Holekamp, Laura Smale, J. Weldon Mcnutt, M. Karen Laurenson, M. G. L. Mills, Bennie I. Osburn

Biology Faculty Articles

Bluetongue is an International Office of Epizootics List A disease described as the century's most economically devastating affliction of sheep. Bluetongue (BLU) viruses were thought to infect only ruminants, shrews, and some rodents, but recently, inadvertent administration of BLU virus-contaminated vaccine resulted in mortality and abortion among domestic dogs. We present evidence of natural BLU virus infection among African carnivores that dramatically widens the spectrum of susceptible hosts. We hypothesize that such infection occurred after ingestion of meat and organs from BLU virus infected prey species. The effect of BLU virus on endangered carnivores such as the cheetah and African …

Agenda: Who Governs The Public Lands: Washington? The West? The Community?, University Of Colorado Boulder. Natural Resources Law Center

Who Governs the Public Lands: Washington? The West? The Community? (September 28-30)

Conference organizers and/or session moderators included University of Colorado School of Law professors David H. Getches, Judith Jacobsen, Lawrence J. MacDonnell, Teresa Rice and Charles F. Wilkinson.

Shifting policy objectives and management approaches for the public lands of the West are provoking heated debate about how these decisions should be made and implemented. Are these policy directions a reflection of the "New West" or are they, in fact, a declaration of "war on the West"? Somewhere between these polarities of view, efforts are underway to open dialogue and reach consensus.

This second annual western lands conference will explore federal initiatives …

Laser Microprobe Mass Spectrometry In Biology And Biomedicine, S. Eeckhaoudt, L. Van Vaeck, R. Gijbels, R. E. Van Grieken

Scanning Microscopy

An overview is given of laser microprobe mass spectrometry (LMMS) in biology and biomedicine (1989-1993). The present instrumentation and its analytical features are surveyed. Applications are presented with special attention on human and animal tissue samples, as well as plant material. The capabilities of LMMS to study the element distribution in histological sections, to identify the chemical composition of inorganic inclusions and to generate structural information from organic compounds are evidenced.

The Ohlone And The Oak Woodlands: Cultural Adaptation In The Santa Clara Valley, Grant William Schick

Research Manuscript Series

Today, Santa Clara Valley consists of a modern industrialized environment distinguished by concrete, pavement and automobiles. These "innovations" made by modern technology began only recently. The environment and ecology of 200 years ago was extremely different from ours today. Filled with many native habitats, it thrived through the inter-dependance of all plant and animal species. In this study, I examine the characteristics of Santa Clara Valley in centuries past and today, in order to understand the vast number of resources which were available to the native inhabitants of the Santa Clara Basin. This paper has its base in cultural ecology, …

Blessed With Orchards, Cheered With Vine: Ideologies Of Agriculture In The Transformation Of Alta California, Virginia C. Czosek

Research Manuscript Series

Prior to the arrival of the first Europeans on her shores, California was ecologically and visually a radically different land than she would become in the nineteenth and twentieth centuries. The first prolonged European intervention in the region in the form of the Spanish missions, as well as the successive waves of . American immigration with the Gold Rush of the 1850's, left a lasting legacy in the form of their tremendous impact on the environment of California. Agriculture fundamentally altered the appearance of the territory, replacing its native environment with a man-made, cultivated one. The groves of oaks and …

Phosphorus Leaching In Soils Amended With Piggery Effluent Or Lime Residues From Effluent Treatment, D. M. Weaver, G. S.P. Ritchie

Food Science and Nutrition

Phosphorus (P) in wastes from piggeries may contribute to the eutrophication of waterways if not disposed of appropriately. Phosphorus leaching, from three soils with different P sorption characteristics (two with low P retention and one with moderate P retention) when treated with piggery effluent (with or without struvite), was investigated using batch and leaching experiments. The leaching of P retained in soil from the application of struvite effluent was determined. In addition, P leaching from lime residues (resulting from the treatment of piggery effluent with lime to remove P) was determined in comparison to superphosphate when applied to the same …

Phosphorus Removal From Piggery Effluents Of Varying Quality Using Lime And Physico-Chemical Treatment Methods., D. M. Weaver, G. S. P. Ritchie

Food Science and Nutrition

The choice of management practices for the treatment of piggery effluent prior to its disposal to waterways or land is governed by the desire to simultaneously minimise the cost of treatment whilst minimising pollution of the environment. Laboratory experiments were conducted to compare the removal of total and total filterable phosphorus (P) (μm) from ortho-phosphate solutions or piggery effluent by hydrated lime or lime kiln dust alone, or from recycled piggery effluent by lime and physico-chemical treatment methods. In addition, the ability of lime to remove P from recycled piggery effluent at an intensive piggery was assessed.

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich

Pitzer Faculty Publications and Research

This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …

Summer Habitat Use Of Littoral-Zone Fishes In Lake Tahoe And The Effects Of Shoreline Structures, D. Beauchamp, E. Byron, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

We used scuba observations to determine summer habitat use and the effects of piers on the littoral-zone fish community in Lake Tahoe, California–Nevada. Habitat complexity declined with depth. Over 50% of the littoral zone less than 2 m deep was composed of complex boulder substrates, but this substrate represented less than 10% of the habitat between 10 and 18 m deep. A severe drought lowered the surface elevation of the lake 2 m and reduced the wetted complex rocky habitat by 20% between the 0- and l0-m isobaths (referenced to the mean lake level of 1,899 m above sea level). …

Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown

Journal of the Arkansas Academy of Science

Lake Fayetteville and Lake Wedington are small reservoirs of about the same size and age that are located in northwestern Arkansas. We collected macrophytes from eleven transects around each reservoir in the autumn of 1993. Justicia (waterwillow), Typha (cat-tail), Scirpus (bulrush), Potamogeton (pondweed), and Zannichellia (horned pondweed) occur in both reservoirs. Justicia occurs most commonly in both reservoirs. The macrophytes of Lake Wedington are organized in a characteristic zonation pattern with bands from shore toward open water of emergent, floating-leaved, then submersed macrophytes. Macrophyte zonation was not as evident in Lake Fayetteville because of the low occurrence of floating leaved …

Phytoplankton Assemblages Associated With A Bloom Of Ptychodiscus Brevis Off The North Carolina Coast, Traycie Lea West

Biological Sciences Theses & Dissertations

A bloom of the dinoflagellate Ptychodiscus brevis occurred off the North Carolina coast in late 1987, and samples were forwarded by NOAA to the Old Dominion University Phytoplankton Laboratory for total phytoplankton analysis. Six sampling stations were chosen to represent different bloom scenarios and these six were clustered into three site groups based on the concentrations of statistically significant taxa. Abundances of phytoplankton taxonomic groups over time were examined in relation to P. brevis concentrations to identify any general tendencies. These results indicated the total phytoplankton concentration, and most taxonomic groups, increased at all three site groups regardless of the …

Synchrotron Radiation Induced X-Ray Microanalysis: A Realistic Alternative For Electron- And Ion-Beam Microscopy?, K. Janssens, F. C. Adams, M. L. Rivers, K. W. Jones

Scanning Microscopy

Synchrotron radiation induced X-ray micro fluorescence analysis (μ-SRXRF) is compared with more conventional microanalytical techniques such as secondary ion microscopy (SIMS) and electron probe X-ray microanalysis (EPXMA) for two typical microanalytical applications. μ-SRXRF and EPXMA are employed for the analysis of individual particles, showing the complementary character of both techniques. By means of element mapping of trace constituents in a heterogeneous feldspar material, the strong and weak points of μ-SRXRF in comparison to EPXMA and SIMS are illustrated. The most striking difference between μ-SRXRF and the other two microanalytical methods is the ability of SRXRF to probe deep into the …

Remote Detection Of Coral 'Bleaching' Using Pulsed-Laser Fluorescence Spectroscopy, J. T. Hardy, F. E. Hoge, J. K. Yungel, Richard E. Dodge

Marine & Environmental Sciences Faculty Articles

Despite their biological and economic importance coral reefs are increasingly threatened by human activities. Recently, 'bleaching' of reefs, i.e. loss of photosynthetic pigmentation, has occurred at numerous globally-distributed sites. A number of environmental stressors, including increased water temperature, can induce bleaching. Several investigators have suggested that the widespread occurrence of coral bleaching represents an early warning signal of global greenhouse warming. Regardless of the cause, the extent of coral bleaching, both regionally and globally, needs to be documented and monitored. We conducted laboratory studies to evaluate the potential of using remotely-sensed laser-induced fluorescence to monitor coral pigmentation. Five species of …
