N. G. Sugihara, J. W. van Wagtendonk, J. Fites-Kaufman, K. E. Shaffer, A. E. Thode, editor(s)
2004, Book chapter, Fire in California ecosystems
This chapter investigates fire as a dynamic ecosystem process by first investigating fire in the context of general ecological theory, then discussing the concept of fire regimes, and finally by developing and applying a new framework for classifying fire regimes that better allows for the understanding of the patterns of...

The objective of this paper is to review research conducted over the past decade on the application of multi-temporal remote sensing for monitoring changes of Arctic tundra lands. Emphasis is placed on results from the National Science Foundation Land–Air–Ice Interactions (LAII) program and on optical remote sensing techniques. Case...
Elements of a predictive model for determining beach closures on a real time basis: the case of 63rd Street Beach Chicago
Greg A. Olyphant, Richard L. Whitman
2004, Environmental Monitoring and Assessment (98) 175-190
Data on hydrometeorological conditions and E. coli concentration were simultaneously collected on 57 occasions during the summer of 2000 at 63rd Street Beach, Chicago, Illinois. The data were used to identify and calibrate a statistical regression model aimed at predicting when the bacterial concentration of the beach water was above...

Element content of Xanthoparmelia scabrosa growing on asphalt in urban and rural New Zealand
J. P. Bennett, D.M. Wright
2004, Bryologist (107) 421-428
Xanthoparmelia scabrosa is a foliose lichen that grows abundantly on pedestrian and automobile asphalt in New Zealand, which are considered inhospitable habitats for lichens. Samples were collected at eight localities ranging from urban streets to very rural roads and analyzed for 28 chemical elements in order to determine elemental chemistry...

Strain accumulation across the Coast Ranges at the latitude of San Francisco, 1994-2000
J.C. Savage, Weijun Gan, W.H. Prescott, J. L. Svarc
2004, Journal of Geophysical Research B: Solid Earth (109)
A 66-monument geodetic array spanning the Coast Ranges near San Francisco has been surveyed more than eight times by GIPS between late 1993 and early 2001. The measured horizontal velocities of the monuments are well represented by uniform, right-lateral, simple shear parallel to N29°W. (The local strike of the San...
A hierarchical spatial model of avian abundance with application to Cerulean Warblers
Wayne E. Thogmartin, John R. Sauer, Melinda G. Knutson
2004, Ecological Applications (14) 1766-1779
Surveys collecting count data are the primary means by which abundance is indexed for birds. These counts are confounded, however, by nuisance effects including observer effects and spatial correlation between counts. Current methods poorly accommodate both observer and spatial effects because modeling these spatially autocorrelated counts within a hierarchical framework...
Water-quality characteristics and trends for selected sites in or near the Earth Resources Observation Systems (EROS) Data Center, South Dakota, 1973-2000
Kathleen M. Neitzert
2004, Water-Resources Investigations Report 2003-4280
This report presents data on water-quality samples that were collected in and near the Earth Resources Observation Systems (EROS) Data Center from 1973 through 2000. The investigation is a collaborated effort between the U.S. Geological Survey, Water Resources Discipline (WRD), and Geography (formerly National Mapping) Discipline, EROS Data Center. A water-quality...
Use of RORA for Complex Ground-Water Flow Conditions
A. T. Rutledge
2004, Water-Resources Investigations Report 2003-4304
The RORA computer program for estimating recharge is based on a condition in which ground water flows perpendicular to the nearest stream that receives ground-water discharge. The method, therefore, does not explicitly account for the ground-water-flow component that is parallel to the stream. Hypothetical finite-difference simulations are used to demonstrate...
Changes in the substrate of rivers in historic mining districts
R.T. Milhous
2004, Conference Paper, Joint Conference on Water Resource Engineering and Water Resources Planning and Management 2000: Building Partnerships
The restoration of rivers in watersheds with historic mining districts has become a topic of interest during the last decade. Rivers restoration in these areas is difficult because the mines and mills can be scattered over a wide area and often small. Many have also been abandoned. This paper presents...
Vegetation response to fire and postburn seeding treatments in juniper woodlands of the Grand Staircase-Escalante National Monument, Utah
P. Evangelista, T.J. Stohlgren, D. Guenther, S. Stewart
2004, Western North American Naturalist (64) 293-305
We compared 3 naturally ignited burns with unburned sites in the Grand Staircase-Escalante National Monument. Each burn site was restored with native and nonnative seed mixes, restored with native seeds only, or regenerated naturally. In general, burned sites had significantly lower native species richness (1.8 vs. 2.9 species), native species...
When should Mayfield model data be discarded?
T.R. Stanley
2004, The Wilson Bulletin (116) 267-269
Much confusion exists over the proper way to handle nest-fate data collected after the fledge date when using the Mayfield method. I provide a simple numerical example showing how use of these data can bias estimates of daily survival probability, and present a likelihood function demonstrating that nest-fate data collected...
The travel cost method and the economic value of leisure time
Aaron J. Douglas, Richard L. Johnson
2004, International Journal of Tourism Research (6) 365-374
Recent estimates of high values for tourist related recreation USA amenity values indicate that allocation of basic water and terrestrial resources to recreation activities should be given precedence over conventional market oriented activities that often degrade or even extirpate the resource. We discuss at length the travel cost method (TCM),...
Rabies in a captive colony of big brown bats (Eptesicus fuscus)
V. Shankar, R. A. Bowen, A. D. Davis, C. E. Rupprecht, T. J. O'Shea
2004, Journal of Wildlife Diseases (40) 403-413
Our research has focused on the ecology of commensal populations of big brown bats (Eptesicus fuscus) in Fort Collins, Colorado (USA), in relation to rabies virus (RV) transmission. We captured 35 big brown bats (Eptesicus fuscus) in late summer 2001 and held them captive for 4.8 mo. The bats were...
Estimating stage-specific daily survival probabilities of nests when nest age is unknown
T.R. Stanley
2004, The Auk (121) 134-147
Estimation of daily survival probabilities of nests is common in studies of avian populations. Since the introduction of Mayfield's (1961, 1975) estimator, numerous models have been developed to relax Mayfield's assumptions and account for biologically important sources of variation. <a...
Empirical evidence for large nonmarket values for water resources: TCM benefits estimates for Lake Powell
Aaron J. Douglas, Richard L. Johnson
2004, International Journal of Water (2) 229-246
The wide acceptance of travel cost method (TCM) nonmarket benefits estimates rests, in part, on the fact that it deploys data on actual expenditures – as opposed to hypothetical behaviour – to estimate benefits conferred. The data for the current analysis was gathered from a survey that was distributed on-site...
