Writing refuge management goals and objectives: a handbook
Robert S. Adamcik, Elizabeth Bell, Don C. DeLong Jr., John H. Schomaker, David B. Hamilton, Murray K. Laubhan, Richard L. Schroeder
2004, Report
Goals and objectives are the unifying elements of successful refuge management. They identify and focus management priorities, provide a context for resolving issues, guide specific projects, provide rationale for decisions, and offer a defensible link among management actions, refuge purpose(s), Service policy, and the National Wildlife Refuge System (Refuge System) mission. Pursuant to Refuge...

Estimating the time of melt onset and freeze onset over Arctic sea-ice area using active and passive microwave data
Gennady I. Belchansky, David C. Douglas, Ilia N. Mordvintsev, Nikita G. Platonov
2004, Remote Sensing of Environment (92) 21-39
Accurate calculation of the time of melt onset, freeze onset, and melt duration over Arctic sea-ice area is crucial for climate and global change studies because it affects accuracy of surface energy balance estimates. This comparative study evaluates several methods used to estimate sea-ice melt and freeze onset dates: (1)...

Comparison of catch and lake trout bycatch in commercial trap nets and gill nets targeting lake whitefish in northern Lake Huron
James E. Johnson, Mark P. Ebener, Kenneth Gebhardt, Roger Bergstedt
2004, Fisheries Research Report 2071
We compared seasonal lake whitefish catch rates, lake trout bycatch, and gearinduced lake trout mortality between commercial trap nets and gill nets in north-central Lake Huron. Onboard monitors recorded catches from 260 gill net and 96 trap net lifts from October 1998 through December 1999. Catch rates for lake whitefish...
Light dependence of selenium uptake by phytoplankton and implications for predicting selenium incorporation into food webs
S.B. Baines, N.S. Fisher, M.A. Doblin, G.A. Cutter, L.S. Cutter, B. Cole
2004, Limnology and Oceanography (49) 566-578
The potentially toxic element selenium is first concentrated from solution to a large but highly variable degree by algae and bacteria before being passed on to consumers. The large loads of abiotic and detrital suspended particles often present in rivers and estuaries may obscure spatial and temporal patterns in Se...
Evaluating microbial purification during soil treatment of wastewater with multicomponent tracer and surrogate tests
S. Van Cuyk, R.L. Siegrist, K. Lowe, R.W. Harvey
2004, Journal of Environmental Quality (33) 316-329
Soil treatment of wastewater has the potential to achieve high purification efficiency, yet the understanding and predictability of purification with respect to removal of viruses and other pathogens is limited. Research has been completed to quantify the removal of virus and bacteria through the use of microbial surrogates and conservative...

Isotopic, geochemical, and temporal characterization of Proterozoic basement rocks in the Quitovac region, northwestern Sonora, Mexico: Implications for the reconstruction of the southwestern margin of Laurentia
A. Iriondo, W. R. Premo, Luis M. Martinez-Torres, J. R. Budahn, William W. Atkinson Jr., D. F. Siems, B. Guaras-Gonzalez
2004, Geological Society of America Bulletin (116) 154-170
A detailed geochemical characterization of 19 representative Proterozoic basement rocks in the Quitovac region in northwestern Sonora, Mexico, has identified two distinct Paleoproterozoic basement blocks that coincide spatially with the previously proposed Caborca and "North America" blocks. New U-Pb zircon geochronology revises their age ranges, the Caborca (1.78-1.69 Ga) and...
Influence of forest management on headwater stream amphibians at multiple spatial scales
Margo Stoddard, John P. Hayes, Janet L. Erickson
2004, Fact Sheet 2004-3018
Background Amphibians are important components of headwater streams in forest ecosystems of the Pacific Northwest (PNW). They comprise the highest vertebrate biomass and density in these systems and are integral to trophic dynamics both as prey and as predators. The most commonly encountered amphibians in PNW headwater streams include the Pacific...

From 8/95 to 2/01, we investigated the ecological effects of intra- and inter-annual variability in freshwater flow through Taylor Creek in southeastern Everglades National Park. Continuous monitoring and intensive sampling studies overlapped with an array of pulsed weather events that impacted physical, chemical, and biological attributes of this region. We...
