Physiological Ecology and Ecohydrology of Coastal Forested Wetlands
Ken W. Krauss
2007, Fact Sheet 2007-3018
The form, function, and productivity of wetland communities are influenced strongly by the hydrologic regime of an area. Wetland ecosystems persist by depending upon surpluses of rainfall, evapotranspiration, soil moisture, and frequency and amplitude of water-level fluctuations. Yet, wetland vegetation can also influence ecosystem water economy through conservative water- and...

Ground-Water Recharge in Minnesota
G. N. Delin, J.D. Falteisek
2007, Fact Sheet 2007-3002
'Ground-water recharge' broadly describes the addition of water to the ground-water system. Most water recharging the ground-water system moves relatively rapidly to surface-water bodies and sustains streamflow, lake levels, and wetlands. Over the long term, recharge is generally balanced by discharge to surface waters, to plants, and to deeper parts...

Melanie R. Darst, Helen M. Light
2007, Open-File Report 2007-1019
Floodplain forests of the Apalachicola River, Florida, are drier in composition today (2006) than they were before 1954, and drying is expected to continue for at least the next 50 years. Drier forest composition is probably caused by water-level declines that occurred as a result of physical changes in the...
