Initial yield to depth relation for water wells drilled into crystalline bedrock - Pinardville quadrangle, New Hampshire
L.J. Drew, J.H. Schuenemeyer, T.R. Amstrong, D. M. Sutphin
2001, Ground Water (39) 676-684
A model is proposed to explain the statistical relations between the mean initial water well yields from eight time increments from 1984 to 1998 for wells drilled into the crystalline bedrock aquifer system in the Pinardville area of southern New Hampshire and the type of bedrock, mean well depth, and...
Regional water-quality analysis of 2,4-D and dicamba in river water using gas chromatography-isotope dilution mass spectrometry
E.M. Thurman, L.R. Zimmerman, D.S. Aga, R. J. Gilliom
2001, International Journal of Environmental Analytical Chemistry (79) 185-198
Gas chromatography with isotope dilution mass spectrometry (GC-MS) and enzyme-linked immunosorbent assay (ELISA) were used in regional National Water Quality Assessment studies of the herbicides, 2,4-D and dicamba, in river water across the United States. The GC-MS method involved solid-phase extraction, derivatized with deuterated 2,4-D, and...
Lichens from St. Matthew and St. Paul Islands, Bering Sea, Alaska
Stephen S. Talbot, Sandra Looman Talbot, John W. Thomson, Wilfred B. Schofield
2001, The Bryologist (104) 47-58
One hundred thirty-nine taxa of lichens including two lichen parasites are reported from St. Matthew and St. Paul Islands in the Bering Sea. Caloplaca lithophila is new to Alaska. Wide-ranging arctic-alpine and boreal species dominate the lichens; a coastal element is moderately represented, while amphi-Beringian species form a minor element....
Littoral zone fish assemblages of northern Cayuga Lake.
James E. McKenna Jr.
2001, Conference Paper, A symposium on environmental research in the Cayuga Lake Watershed
Fish assemblages from northern Cayuga Lake were examined for patterns in temporal structure. Fish assemblages changed significantly between seasons. Bluegill (Lepomis macrochirus), bluntnose minnow (Pimephales notatus), and smallmouth bass (Micropterus dolomieu) formed the basis for most assemblages, but the spring assemblage was dominated by common carp (Cyprinus carpio). Correlations between...
Stratigraphy and lithofacies of Lisburne Group carbonate rocks (Carboniferous - Permian) in the National Petroleum Reserve - Alaska
Julie A. Dumoulin, Kenneth J. Bird
David W. Houseknecht, editor(s)
2001, SEPM Core Workshop Notes (21) 141-166
Carbonate rocks of the Lisburne Group (Carboniferous-Permian) occur widely throughout northern Alaska. In the NPRA, seismic mapping and well penetrations show that the Lisburne occurs throughout the subsurface except in northernmost NPRA where it is missing by depositional onlap. Lisburne strata encountered in 11 exploratory wells in the northern part...
The Great Auk [Book review]
John F. Piatt
2001, Marine Ornithology: Journal of Seabird Research and Conservation (29) 65-66
Human obsession with the Great Auk or Garefowl Pinguinus impennis is what this book is about, and it further fuels the fire of our fascination. As Fuller concludes in his introduction: ‘The Great Auk, large and plump, has tempted man since the dawn of history. Whatever the precise reasons for...
Recommended features of protocols for long-term ecological monitoring
Karen L. Oakley, Susan L. Boudreau, Sioux-Z Humphrey
2001, Conference Paper, Crossing boundaries in park management: Proceedings of the 11th conference on research and resource management in parks and on public lands
In 1991, the National Park Service (NPS) selected seven parks to serve as prototypes for development of a long-term ecological monitoring program. Denali National Park and Preserve was one of the prototype parks selected. The principal focus of this national program was to detect and document resource changes and to...
Rapid fluid disruption: A source for self-potential anomalies on volcanoes
M.J.S. Johnston, J.D. Byerlee, D. Lockner
2001, Journal of Geophysical Research B: Solid Earth (106) 4327-4335
Self-potential (SP) anomalies observed above suspected magma reservoirs, dikes, etc., on various volcanoes (Kilauea, Hawaii; Mount Unzen, Japan; Piton de la Fournaise, Reunion Island, Miyake Jima, Japan) result from transient surface electric fields of tens of millivolts per kilometer and generally have a positive polarity. These SP anomalies are usually...
Does clutch size evolve in response to parasites and immunocompetence?
T. E. Martin, A.P. Moller, S. Merino, J. Clobert
2001, Proceedings of the National Academy of Sciences of the United States of America (98) 2071-2076
Parasites have been argued to influence clutch size evolution, but past work and theory has largely focused on within-species optimization solutions rather than clearly addressing among-species variation. The effects of parasites on clutch size variation among species can be complex, however, because different parasites can induce age-specific differences in mortality...
The effects of electroshock on immune function and disease progression in juvenile spring chinook salmon
S. P. VanderKooi, A.G. Maule, C.B. Schreck
2001, Transactions of the American Fisheries Society (130) 397-408
Although much is known about the effects of electroshock on fish physiology, consequences to the immune system and disease progression have not received attention. Our objectives were to determine the effects of electroshock on selected immune function in juvenile spring chinook salmon Oncorhynchus tshawytscha, the mechanism of any observed alteration,...
Historical trace metal accumulation in the sediments of an urbanized region of the Lake Champlain watershed, Burlington, Vermont
E.L. Mecray, J.W. King, P.G. Appleby, A.S. Hunt
2001, Water, Air, & Soil Pollution (125) 201-230
This study documents the history of pollution inputs in the Burlington region of Lake Champlain, Vermont using measurements of anthropogenic metals (Cu, Zn, Cr, Pb, Cd, and Ag) in four age-dated sediment cores. Sediments record a history of contamination in a region and can be used to assess the changing...
