Estimating hydraulic properties of the Floridan Aquifer System by analysis of earth-tide, ocean-tide, and barometric effects, Collier and Hendry Counties, Florida
Michael L. Merritt
2004, Water-Resources Investigations Report 2003-4267
Aquifers are subjected to mechanical stresses from natural, non-anthropogenic, processes such as pressure loading or mechanical forcing of the aquifer by ocean tides, earth tides, and pressure fluctuations in the atmosphere. The resulting head fluctuations are evident even in deep confined aquifers. The present study was conducted for the purpose...

David L. Stannard, Donald O. Rosenberry, Thomas C. Winter, Renee S. Parkhurst
2004, Wetlands (24) 498-513
Micrometeorological measurements of evapotranspiration (ET) often are affected to some degree by errors arising from limited fetch. A recently developed model was used to estimate fetch-induced errors in Bowen-ratio energy-budget measurements of ET made at a small wetland with fetch-to-height ratios ranging from 34 to 49....

The Bemidji aquifer in Minnesota, USA is a well-studied site of subsurface petroleum contamination. The site contains an anoxic groundwater plume where soluble petroleum constituents serve as an energy source for a region of methanogenesis near the source and bacterial Fe(III) reduction further down gradient. Methanogenesis apparently begins when...
Coping with mist-net capture-rate bias: Canopy height and several extrinsic factors
Elizabeth P. Mallory, Nicholas V. L. Brokaw, Steven C. Hess
2004, Studies in Avian Biology (29) 151-160
Many factors other than a species' actual abundance can affect mist-net capture rates. We used ANCOVA models to quantify some potential biases and control their effects, producing adjusted estimates of capture rates that are more directly comparable among mist-net stations. Data came from 46 two-day mist-net sessions from September 1990...

2004, Conference Paper, Proceedings 10th annual Whirling Disease Symposium: "Whirling disease management: practicalities and realities": Grand American Hotel, Savory Salon, Salt Lake City, Utah, March 2-3, 2004
Dense populations of T. tubifex are generally associated with habitats dominated by fine sediments and enriched organic material (e.g. Krueger, 2002). Management of whirling disease positive systems is entering a new phase where channel modifications are being implemented to reduce or isolate this type of habitat. These management...
