Water Quality Assessment of the Trinity River Basin, Texas - Pesticides in a Suburban Watershed, Arlington, 1993-94 Water Quality Assessment of the Trinity River Basin, Texas - Pesticides in a Suburban Watershed, Arlington, 1993-94
The Trinity River Basin was among the first 20 hydrologic systems under full inplementation of the National Water Quality Assessment (NAWQA) Program. Planning and analysis of existing information began in 1991. Intensive water-quality data collection began in 1993. As a part of the NAWQA Program, pesticide samples were taken from surface water, ground water, streambed sediment, and...

Southeastern freshwater fishes Southeastern freshwater fishes
North America has the richest fauna of temperate freshwater fishes in the world, with about 800 native species in the waters of Canada and the United States. The center of this diversity is in the southeastern United States, where as many as 500 species may exist (62% of the continental fauna north of Mexico). Many coastal marine species also enter fresh waters of the Southeast, and at...

Integration of manatee life-history data and population modeling Integration of manatee life-history data and population modeling
Aerial counts and the number of deaths have been a major focus of attention in attempts to understand the population status of the Florida manatee (Trichechus manatus latirostris). Uncertainties associated with these data have made interpretation difficult. However, knowledge of manatee life-history attributes increased and now permits the development of a population model. We describe a

Determination of selection gradients using multiple regression versus Structural Equation Modeling (SEM) Determination of selection gradients using multiple regression versus Structural Equation Modeling (SEM)
Selection studies involving multiple intercorrelated independent variables have employed multiple regression analysis as a means to estimate and partition natural and sexual selection's direct and indirect effects. These statistical models assume that independent variables are measured without error. Most would conclude that such is not the case in the field studies for which these...
