C.C. McIvor, N.L. Silverman
2010, Wetlands Ecology and Management (18) 627-635
Sampling fishes in vegetated intertidal wetlands is logistically challenging. We modified the 2 ?? 3-m2 bottomless lift net developed for sampling nekton (fish and decapod crustaceans) on the surface of salt marshes for use in tidal mangrove forests with a woody (as opposed to herbaceous) underground root system. As originally...

Dennis W. Rondorf, Gary L. Rutz, Jodi C. Charrier
2010, Report
McNary Lock and Dam were completed in 1953, creating McNary Reservoir, or Lake Wallula. The shoreline of the reservoir is federally owned and as a result the U.S. Army Corps of Engineers (USACE) has certain land and fish habitat management responsibilities to balance with other multipurpose benefits. The Endangered Species...
Multiple well-shutdown tests and site-scale flow simulation in fractured rocks
Claire R. Tiedeman, Pierre J. Lacombe, Daniel J. Goode
2010, Groundwater (48) 401-415
A new method was developed for conducting aquifer tests in fractured-rock flow systems that have a pump-and-treat (P&T) operation for containing and removing groundwater contaminants. The method involves temporary shutdown of individual pumps in wells of the P&T system. Conducting aquifer tests in this manner has several advantages, including (1)...

Comparison of transport and attachment behaviors of Cryptosporidium parvum oocysts and oocyst-sized microspheres being advected through three minerologically different granular porous media
Arvind Mohanram, Chittaranjan Ray, Ronald W. Harvey, David W. Metge, Joseph N. Ryan, Jon Chorover, D. D. Eberl
2010, Water Research (44) 5334-5344
In order to gain more information about the fate of Cryptosporidium parvum oocysts in tropical volcanic soils, the transport and attachment behaviors of oocysts and oocyst-sized polystyrene microspheres were studied in the presence of two soils. These soils were chosen because of their differing chemical and physical properties, i.e., an organic-rich (43–46%...
Fuel buildup and potential fire behavior after stand-replacing fires, logging fire-killed trees and herbicide shrub removal in Sierra Nevada forests
Thomas W. McGinnis, Jon E. Keeley, Scott L. Stephens, Gary B. Roller
2010, Forest Ecology and Management (260) 22-35
Typically, after large stand-replacing fires in mid-elevation Sierra Nevada forests, dense shrub fields occupy sites formerly occupied by mature conifers, until eventually conifers overtop and shade out shrubs. Attempting to reduce fuel loads and expedite forest regeneration in these areas, the USDA Forest Service often disrupts this cycle by the...
