Relative costs of prebasic and prealternate molts for male blue-winged teal Relative costs of prebasic and prealternate molts for male blue-winged teal
We compared masses of definitive basic and alternate plumages of male Blue-winged Teal (Anas discors) to evaluate the hypothesis that nutritional investments in basic and alternate plumages are related to the duration that plumages are worn and to assess the relative costs of prebasic and prealternate molts. Because these plumages are worn by males for approximately equal durations, we...

Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas Long-term growth trends of baldcypress (Taxodium distichum (L.) rich.) at Caddo Lake, Texas
Caddo Lake, situated on the border of northeast Texas and northwest Louisiana, USA is a medium-sized lake dominated by stands of baldcypress (Taxodiwn distichum). A study of tree growth was initiated at Caddo Lake to address concerns about the health of the baldcypress ecosystem. The lake has been subjected to several dramatic water-level changes over the past 200 years, including water...

Hydrogeologic framework of western Cape Cod, Massachusetts Hydrogeologic framework of western Cape Cod, Massachusetts
The aquifer of western Cape Cod consists of several hydrogeologic units composed of sand, gravel, silt, and clay (fig. 1) that were deposited during the late Wisconsinan glaciation of New England. The aquifer is a shallow, unconfined hydrologic system in which ground-water flows radially outward from the apex of the ground-water mound near the center of the peninsula toward the coast...

A spatial decision support system for coastal management: A research project at the National Wetlands Research Center of the U.S. Geological Survey A spatial decision support system for coastal management: A research project at the National Wetlands Research Center of the U.S. Geological Survey
Environmental resource managers and scientists are being challenged in developing strategies to manage complex coastal systems. From an ecological perspective, there are myriad dynamic, interrelated natural and human-induced processes that affect the health and stability of coastal systems. However, the problems associated with managing coastal resources usually transcend purely...
