Evaluation of two oral baiting systems for wild rodents
Terry E. Creekmore, William Fletcher, David E. Stallknecht
1998, Journal of Wildlife Diseases (34) 369-372
Tetracycline hydrochloride (TC)-treated peanut butter or rodent chow baits were distributed during March 1990, on separate 0.53 ha sites in Oglethorpe County, Georgia (USA). Rodents were trapped on a control site prior to bait distribution and on two baited sites 6 days post-distribution. Cleaned skulls from euthanized mammals were grossly...

Flooding and forest succession in a modified stretch along the Upper Mississippi River
Yao Yin
1998, Regulated Rivers: Research & Management (14) 217-225
This research examines the effect of a rare flood on floodplain forest regeneration in a 102-km stretch of the Mississippi River beginning 21 km above the mouth of the Ohio River. The river has been restricted by levees and navigation structures and subjected to sediment dredging to maintain a stable...

Predictive double-layer modeling of metal sorption in mine-drainage systems

1998, Book chapter, Adsorption of metals by geomedia: Variables, mechanisms, and model applications
Previous comparison of predictive double-layer modeling and empirically derived metal-partitioning data has validated the use of the double-layer model to predict metal sorption reactions in iron-rich mine-drainage systems. The double-layer model subsequently has been used to model data collected from several mine-drainage sites in Colorado with diverse geochemistry and geology....

Environmental modification of gillraker number in coregonine fishes
Thomas N. Todd
1998, Book chapter, Biology and management of Coregonid fishes-1996
Gillraker number, one of the most important taxonomic characters in the Coregoninae, has been considered genetically determined and not environmentally modifiable. However, laboratory-reared progeny of Coregonus alpenae, C. artedi, C. clupeaformis, C. hoyi, C. kiyi, C. zenithicus, and Prosopium cylindraceum generally had fewer gillrakers than the wild parents from which...
Fundamentals of isotope geochemistry
Carol Kendall, Eric A. Caldwell
1998, Book chapter, Isotope tracers in catchment hydrology
The dominant use of isotopes in catchment research in the last few decades has been to trace sources of waters and solutes. Generally, such data were evaluated with simple mixing models to determine how much was derived from either of the two (sometimes three) constant-composition sources. This chapter illustrates the...

Edwards, Harold R. House, Emi Ito, Ramon O. Aravena, Joseph F. Whelan
1998, Book chapter, Isotope tracers in catchment hydrology
In addition to providing an understanding of processes within a catchment system, isotopic techniques have been instrumental in providing reconstructions of catchment climate and other environmental indicators at various time scales. Many recent changes are a direct consequence of anthropogenic activities. Isotopic analysis serves as a valuable tool for distinguishing...
Using transport model interpretations of tracer tests to study microbial processes in groundwater
Richard L. Smith, Stephen P. Garabedian
1998, Book chapter, Mathematical modeling in microbial ecology
It has long been known that microorganisms affect the geochemistry of groundwater. But despite this recognition, little detailed information is available regarding the rates and the factors controlling microbial processes in groundwater. Part of the reason stems from the relatively inaccessible nature of most groundwater and the difficulties encountered in...

Use of restored riparian habitat by the endangered least Bell's vireo (Vireo bellii pusillus)
B.E. Kus
1998, Restoration Ecology (6) 75-82
A primary objective of riparian restoration in California is the creation of habitat for endangered species. Four restoration sites in San Diego County were monitored between 1989 and 1993 and evaluated for their suitability as nesting habitat for Vireo bellii pusillus (Least Bell's Vireo), a state and federally endangered obligate riparian breeder....

Rates of volcanic CO2 degassing from airborne determinations of SO2 Emission rates and plume CO2SO2: test study at Pu′u ′O′o Cone, Kilauea Volcano, Hawaii
Terrence M. Gerlach, Kenneth A. McGee, A. Jefferson Sutton, Tamar Elias
1998, Geophysical Research Letters (25) 2675-2678
We present an airborne method that eliminates or minimizes several disadvantages of the customary plume cross-section sampling method for determining volcanic CO2 emission rates. A LI-COR CO2analyzer system (LICOR), a Fourier transform infrared spectrometer system (FTIR), and a correlation spectrometer (COSPEC) were used to constrain the plume CO2/SO2 and the...
Sediment delivery to the Gulf of Alaska: Source mechanisms along a glaciated transform margin
M.R. Dobson, D. O'Leary, M. Veart
1998, Geological Society Special Publication (129) 43-66
Sediment delivery to the Gulf of Alaska occurs via four areally extensive deepwater fans, sourced from grounded tidewater glaciers. During periods of climatic cooling, glaciers cross a narrow shelf and discharge sediment down the continental slope. Because the coastal terrain is dominated by fjords and a narrow, high-relief Pacific watershed,...
Assessing map accuracy in a remotely sensed, ecoregion-scale cover map
T.C. Edwards Jr., Gretchen G. Moisen, D.R. Cutler
1998, Remote Sensing of Environment (63) 73-83
Landscape- and ecoregion-based conservation efforts increasingly use a spatial component to organize data for analysis and interpretation. A challenge particular to remotely sensed cover maps generated from these efforts is how best to assess the accuracy of the cover maps, especially when they can exceed 1000 s/km2 in size. Here...
