2001, The George Wright Forum (18) 26-39
This paper describes the results of searches of herbarium and museum collections and databases for records of vertebrate and vascular plant specimens that had been collected in 15 midwestern National Park System units. The records of these specimens were previously unknown to the National Park Service (NPS). In the course...
Unsuccessful initial search for a midmantle chemical boundary with seismic arrays
J.E. Vidale, G. Schubert, P.S. Earle
2001, Geophysical Research Letters (28) 859-862
Compositional layering of the midmantle has been proposed to account for seismic and geochemical patterns [van der Hilst and Karason, 1999], and inferred radiogenic heat source concentrations [Kellogg et al., 1999]. Compositional layering would require thermal boundary layers both above and below an interface. We construct a minimal 1-D model...
Droughts, epic droughts and droughty centuries - lessons from a California paleoclimatic record: a PACLIM 2001 meeting report
M. D. Dettinger
2001, Interagency Ecological Program Newsletter (14) 51-53
During the early 1990s (but echoing studies by S.T. Harding at the University of California, from as early as the 1930s), several lines of paleoclimate evidence in and around the Sierra Nevada Range have provided the water community in California with some real horror stories. By studying ancient tree stumps...

Quantitative real-time PCR has been used to measure fibropapilloma-associated turtle herpesvirus (FPTHV) pol DNA loads in fibropapillomas, fibromas, and uninvolved tissues of green, loggerhead, and olive ridley turtles from Hawaii, Florida, Costa Rica, Australia, Mexico, and the West Indies. The viral DNA loads from tumors obtained from terminal animals were...
Assessing large-scale surveyor variability in the historic forest data of the original U.S. Public Land Survey
K.L. Manies, D.J. Mladenoff, E.V. Nordheim
2001, Canadian Journal of Forest Research (31) 1719-1730
The U.S. General Land Office Public Land Survey (PLS) records are a valuable resource for studying pre-European settlement vegetation. However, these data were taken for legal, not ecological, purposes. In turn, the instructions the surveyors followed affected the data collected. For this reason, it has been suggested that the PLS...
Size characteristics of stones ingested by common loons
J. Christian Franson, Scott P. Hansen, Mark Pokras, Rose Miconi
2001, The Condor (103) 189-191
Common Loon (Gavia immer) carcasses recovered in New England had more stones of greater combined mass in their stomachs than loons from the southeastern United States. Stones retained in sieves with mesh sizes between 4.75 and 8.00 mm accounted for the greatest percentage (by mass) of grit in loon stomachs....

Origin of late Quaternary dune fields on the Southern High Plains of Texas and New Mexico
D.R. Muhs, V.T. Holliday
2001, Geological Society of America Bulletin (113) 75-87
Mostly stabilized late Holocene eolian sands on the Southern High Plains of the United States were studied to determine their origins and to assess whether present dune stability depends more strongly on sediment supply, sediment availability, or transport limitations. Geomorphic, sedimentological, and geochemical trends indicate that late Holocene dunes formed...

Short-duration electrical immobilization of lake trout
Mark P. Gaikowski, William H. Gingerich, Steve Gutreuter
2001, North American Journal of Fisheries Management (21) 381-392
Chemical anesthetics induce stress responses, and most leave residues in fish tissues that require a certain withdrawal time before the animal can be released into the environment. Therefore, alternatives are needed in cases when fish must be released immediately, for example, during egg-collecting operations or after implanting elastomer tags. To...

2001, Journal of Geophysical Research B: Solid Earth (106) 13581-13597
Array data from a seismic experiment carried out at Kilauea Volcano, Hawaii, in February 1997, are analyzed by the frequency-slowness method. The slowness vectors are determined at each of three small-aperture seismic antennas for the first arrivals of 1129 long-period (LP) events and 147 samples of volcanic tremor. The source...
Adiabatic temperature changes of magma-gas mixtures during ascent and eruption
L.G. Mastin, M.S. Ghiorso
2001, Contributions to Mineralogy and Petrology (141) 307-321
Most quantitative studies of flow dynamics in eruptive conduits during volcanic eruptions use a simplified energy equation that ignores either temperature changes, or the thermal effects of gas exsolution. In this paper we assess the effects of those simplifications by analyzing the influence of equilibrium gas exsolution and expansion on...
Habitat fragmentation effects on birds in grasslands and wetlands: A critique of our knowledge
Douglas H. Johnson
2001, Great Plains Research (11) 211-231
Habitat fragmentation exacerbates the problem of habitat loss for grassland and wetland birds. Remaining patches of grasslands and wetlands may be too small, too isolated, and too influenced by edge effects to maintain viable populations of some breeding birds. Knowledge of the effects of fragmentation on bird populations is critically...
Coral bleaching, hurricane damage, and benthic cover on coral reefs in St. John, U.S. Virgin Islands: A comparison of surveys with the chain transect method and videography
C.S. Rogers, J. Miller
2001, Bulletin of Marine Science (69) 459-470
The linear chain transect method and videography were used to quantify the percent cover by corals, macroalgae, gorgonians, other living organisms, and substrate along permanent transects on two fringing reefs off St. John. Both methods were used simultaneously on Lameshur reef in November 1998, and on Newfound reef in March...

Loudoun County, Virginia, which is located about 50 km to the west of Washington, DC, was the site of intensive suburban development during the 1980s and 1990s. In the western half of the county, the source of water for domestic use has been from wells drilled into the fractured crystalline...
Mean and modal ϵ in the deaggregation of probabilistic ground motion
Stephen C. Harmsen
2001, Bulletin of the Seismological Society of America (91) 1537-1552
An important element of probabilistic seismic-hazard analysis (PSHA) is the incorporation of ground-motion uncertainty from the earthquake sources. The standard normal variate ϵ measures the difference between any specified spectral-acceleration level, or SA0, and the estimated median spectral acceleration from each probabilistic source. In this article, mean and modal values of ϵ for...
