Assessment of fish assemblages and minimum sampling effort required to determine botic integrity of large rivers in southern Idaho, 2002
Terry R. Maret, D.S. Ott
2004, Water-Resources Investigations Report 2003-4274
A critical issue surrounding biomonitoring in large rivers (fifth- through seventh-order) is the minimum sampling-reach distance required to collect an adequate number of fish to represent the fish assemblage within a reach. Excessive sampling effort (excessive reach length) is costly in terms of work hours, reduces the number of sites that can...

Gross primary productivity of the true steppe in central Asia in relation to NDVI: scaling up CO2 fluxes
Tagir G. Gilmanov, Douglas A. Johnson, Nicanor Z. Saliendra, Kanat Akshalov, Bruce K. Wylie
2004, Environmental Management (33) S492-S508
Compared to other characteristics of CO2 exchange, gross primary productivity (P g ) is most directly related to photosynthetic activity. Until recently, it was considered difficult to obtain measurement-based P g . The objective of our study was to evaluate if P g can be estimated from continuous CO2 flux measurements using nonlinear identification...

2004, International Journal of Plant Sciences (165) 805-816
We examined net photosynthesis, transpiration, stomatal conductance, and leaf fluctuating asymmetry on two species (Rhus copallinum and Ipomoea pandurata) as indicators of stress at nine sites across a gradient of soil disturbance at Fort Benning, Georgia. There were three sites for each of three disturbance levels. Physical habitat disturbance was caused by...
Evaluation of volatilization as a natural attenuation pathway for MTBE
Matthew A. Lahvis, Arthur L. Baehr, Ronald J. Baker
2004, Groundwater (42) 258-267
Volatilization and diffusion through the unsaturated zone can be an important pathway for natural attenuation remediation of methyl tert-butyl ether (MTBE) at gasoline spill sites. The significance of this pathway depends primarily on the distribution of immiscible product within the unsaturated zone and the relative magnitude of aqueous-phase advection (ground...

Jon Hortness, Charles Berenbrock
2004, Water-Resources Investigations Report 2003-4261
Methods for estimating magnitudes of peak flows with recurrence intervals of 1.5 and 2.33 years were developed for ungaged sites on streams throughout Idaho.
