Investigations Of The Effects Of Synthetic Chemicals On The Endocrine System Of Common Carp In Lake Mead, Nevada And Arizona, Michael R. Rosen, Steven L. Goodbred, Reynaldo Patiño, Thomas J. Leiker, Erik Orsak

United States Geological Survey: Publications

Lake Mead is the largest reservoir by volume in the United States and was created by the construction of the 221-meter high Hoover Dam in 1935 at Black Canyon on the lower Colorado River between Nevada and Arizona (fig. 1). Inflows of water into the lake include three rivers, Colorado, Virgin, and Muddy; as well as Las Vegas Wash, which is now perennial because of discharges from municipal wastewater treatment plants (Covay and Leiker, 1998) and urban stormwater runoff. As the population within the Las Vegas Valley began to increase in the 1940s, the treated effluent volume also has increased …

Applications Of Trace-Element And Stable-Isotope Geochemistry To Wildlife Issues, Yellowstone National Park And Vicinity, Maurice A. Chaffee, Wayne C. Shanks Iii, Robert O. Rye, Charles C. Shwartz, Monique G. Adams, Robert R. Carlson, James G. Crock, Pamela A. Gemery-Hill, Kerry A. Gunther, Cynthia L. Kester, Harley D. King, Shannon R. Podruzny

United States Geological Survey: Publications

Reconnaissance investigations have been conducted to identify how geochemical techniques can be applied to biological studies to assist wildlife management in and near Yellowstone National Park (the Park). Many elements (for example, As, B, Be, Ce, Cl, Cs, F, Hg, K, Li, Mo, Rb, S, Sb, Si, and W) are commonly enriched in (1) thermal waters in the Yellowstone area, (2) rocks altered by these waters, (3) sinter and travertine deposits, and (4) soils and stream sediments derived from these rocks. Some of these elements, such as As, F, Hg, and Mo, may be toxic to wildlife and could be …

The Question Of Recharge To The Deep Thermal Reservoir Underlying The Geysers And Hot Springs Of Yellowstone National Park, Robert O. Rye, Alfred H. Truesdell

United States Geological Survey: Publications

The extraordinary number, size, and unspoiled beauty of the geysers and hot springs of Yellowstone National Park (the Park) make them a national treasure. The hydrology of these special features and their relation to cold waters of the Yellowstone area are poorly known. In the absence of deep drill holes, such information is available only indirectly from isotope studies. The δD-δ¹⁸O values of precipitation and cold surface-water and ground-water samples are close to the global meteoric water line (Craig, 1961). δD values of monthly samples of rain and snow collected from 1978 to 1981 at two stations in …

Geochemistry Of Sublacustrine Hydrothermal Deposits In Yellowstone Lake—Hydrothermal Reactions, Stable-Isotope Systematics, Sinter Deposition, And Spire Formation, Wayne C. Shanks Iii, Jeffrey C. Alt, Lisa A. Morgan

United States Geological Survey: Publications

Geochemical and mineralogical studies of hydrothermal deposits and altered vent muds from the floor of Yellowstone Lake indicate that these features form due to hydrothermal fluid quenching in shallow flow conduits or upon egress into bottom waters. Siliceous precipitates occur as conduits within the uppermost sediments, as tabular deposits that form along sedimentary layers, and as spires as much as 8 m tall that grow upward from crater-like depressions on the lake bottom. These deposits are enriched in As, Cs, Hg, Mo, Sb, Tl, and W.

Variations in major-element geochemistry indicate that subaerial sinters from West Thumb and spire interiors …

The Life Cycle Of Gold Deposits Near The Northeast Corner Of Yellowstone National Park—Geology, Mining History, And Fate, Bradley S. Van Gosen

United States Geological Survey: Publications

Henderson Mountain, near Cooke City, Mont., about 4.5 mi northeast of the northeast entrance to Yellowstone National Park (the Park), hosts identified resources of at least 2.3 million ounces of gold, 8.9 million ounces of silver, and 130 million pounds of copper. The mineral deposits formed by selective replacement of calcareous blocks and clasts in a complex breccia pipe (the Homestake deposit), and concurrent skarn development replaced limestone adjacent to the breccia pipe (the Miller Creek deposit). The breccia pipe and mineral deposits formed in the middle Eocene during intrusion of the dacitic Homestake stock.

Concentrations Of Metals In Aquatic Invertebrates From The Ozark National Scenic Riverways, Missouri, Christopher J. Schmitt, William G. Brumbaugh, John M. Besser, Thomas W. May

United States Geological Survey: Publications

This report summarizes the findings of a study conducted as a pilot for part of a park-wide monitoring program being developed for the Ozark National Scenic Riverways (ONSR) of southeastern Missouri. The objective was to evaluate using crayfish (Orconectes spp.) and Asian clam (Corbicula fluminea) for monitoring concentrations of metals associated with lead-zinc mining. Lead-zinc mining presently (2007) occurs near the ONSR and additional mining has been proposed. Three composite samples of each type (crayfish and Asian clam), each comprising ten animals of approximately the same size, were collected during late summer and early fall of 2005 …

Butterfly Responses To Prairie Restoration Through Fire And Grazing, Jennifer A. Vogel, Diane M. Debinski, Rolf R. Koford, James R. Miller

United States Geological Survey: Staff Publications

The development of land for modern agriculture has resulted in losses of native prairie habitat. The small, isolated patches of prairie habitat that remain are threatened by fire suppression, overgrazing, and invasion by non-native species. We evaluated the effects of three restoration practices (grazing only, burning only, and burning and grazing) on the vegetation characteristics and butterfly communities of remnant prairies. Total butterfly abundance was highest on prairies that were managed with burning and grazing and lowest on those that were only burned. Butterfly species richness did not differ among any of the restoration practices. Butterfly species diversity was highest …

Factors Influencing Movement Probabilities Of Big Brown Bats (Eptesicus Fuscus) In Buildings, Laura E. Ellison, Thomas J. O’Shea, Daniel J. Neubaum, Richard Bowen

United States Geological Survey: Staff Publications

We investigated movements of female big brown bats (Eptesicus fuscus) roosting in maternity colonies in buildings in Fort Collins, Colorado (USA), during the summers of 2002, 2003, and 2005. This behavior can be of public health concern where bats that may carry diseases (e.g., rabies) move among buildings occupied by people. We used passive integrated transponders (PIT tags) to mark individual bats and hoop PIT readers at emergence points to passively monitor the use of building roosts by marked adult females on a daily basis during the lactation phase of reproduction. Multi-strata models were used to examine movements …

Winn, Douglas L. Crawford

United States Environmental Protection Agency: Publications

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals and populations interact with their environment. In this paper we summarize an extensive body of work examining the adaptive responses of Fundulus species to environmental conditions, and describe how this research has contributed importantly to our understanding of physiology, gene regulation, toxicology, and ecological and evolutionary genetics of teleosts and other vertebrates. These explorations have reached a critical juncture at which advancement is hindered by the lack of genomic resources for these …

World Bank -Cpa Conflict: The Struggle To Define Human Rights And Development In The Philippines, Adam B. Robbins

Honors Theses

This thesis analyzes the interactions between the World Bank (hereafter, the Bank) and the Cordillera Peoples Alliance (CPA), an indigenous and environmental advocacy group based in the Cordillera region of Luzon, in the Philippines. Using data gathered through both text-based and participatory research methods, I analyze the discursive relationship and violent confrontations between the two organizations. Conflicting development and human rights values cause the majority of these conflicts. I focus on how each organization enacts development and human rights, and how this leads to conflict. Ultimately, I intend for this thesis to offer practical guidance for the reader involved in …
