Nitrate in ground water and stream base flow in the lower Susquehanna River Basin, Pennsylvania and Maryland Nitrate in ground water and stream base flow in the lower Susquehanna River Basin, Pennsylvania and Maryland
High concentrations of nitrate in both ground and surface water have been identified as a significant water-quality issue in the Lower Susquehanna River Basin. This report uses data collected by the National Water Quality Assessment (NAWQA) Program in the basin and compares nitrate concentrations found in ground water and surface water on both a spatial and temporal basis and relates...

Contaminants in the Gulf of Maine-What's here and should we worry? Contaminants in the Gulf of Maine-What's here and should we worry?
The Gulf of Maine is a dynamic environment that has highly variable bottom type and localized depositional and transport processes. It is used and impacted by the people around it who hope to use the marine system for many purposes such as fishing, recreation, housing, sewage and dumped disposal, shipping, recreation, and preservation. In order to identify "pollution", which is defined...

The Bumpus house sparrow data: A reanalysis using structural equation models The Bumpus house sparrow data: A reanalysis using structural equation models
We analysed the data of H.C. Bumpus on the survival of house sparrows (Passer domesticus) using structural equation modelling techniques. Using data on seven morphological variables measured by Bumpus, we tested and confirmed a three-factor model that characterized physical attributes for general size, leg size and head size. Although males were physically larger than females, we found...

Small watershed studies: Analytical approaches for understanding ecosystem response to environmental change Small watershed studies: Analytical approaches for understanding ecosystem response to environmental change
Biogeochemical studies in small watersheds provide an analytical approach to understand how ecosystems respond to natural climatic variations and human-induced environmental change. Small watersheds, usually less than 5 km2, are small enough to permit characterization and understanding of ecosystem processes within relatively simple, homogeneous biological and physical settings; yet they...
