R.A. Konisky, D.M. Burdick, M. Dionne, H.A. Neckles
2006, Restoration Ecology (14) 516-525
We compiled salt marsh monitoring datasets from 36 complete or imminent restoration projects in the Gulf of Maine to assess regional monitoring and restoration practices. Data were organized by functional indicators and restoration project types (culvert replacement, excavation works, or ditch plugging) then pooled to generate mean values for...
An interface between the Agricultural Non-Point Source (AGNPS) pollution model and the ERDAS Imagine Geographic Information System (GIS)
Michael P. Finn, E. Lynn Usery, Douglas J. Scheidt, Gregory M. Jaromack, Timothy D. Krupinski
2006, Geographic Information Sciences (12) 10-20
The U.S. Department of Agriculture developed the Agricultural Non-Point Source (AGNPS) pollution model. The AGNPS pollution model simulates the behavior of runoff, sediment, and nutrient transport from watersheds that have agriculture as their prime use. This model has been used extensively by scientists conducting hydrologic or water quality analyses using...

Solute transport processes
A. Kemna, Andrew Binley, Frederick D. Day-Lewis, Andreas Englert, Bulent Tezkan, Jan Vanderborght, Harry Vereecken, Peter Winship
2006, Book chapter
Soils and aquifers are major compartments of the subsurface environment, which together control the terrestrial hydrological cycle. This subsurface is important for water resources and also as repository for municipal, industrial, and government waste. Aquifers are typically recharged by natural rainfall entering the soil profile and leaching into deeper soil...

2006, Ecological Monographs (76) 565-583
Tree islands are centers of biodiversity within the Florida Everglades, USA, but the factors controlling their distribution, formation, and development are poorly understood. We use pollen assemblages from tree islands throughout the greater Everglades ecosystem to reconstruct the timing of tree island formation, patterns of development, and response to specific...
