Globally, many rivers are experiencing declining water quality, for example, with altered
levels of sediments, salts, and nutrients. Effective water quality management requires a …

Ecology and natural history have a long tradition of interest in the spatial patterning and
geographic distribution of organisms. The latitudinal and altitudinal distribution of vegetative …

Nutrient (C, N, and P) concentration changes were measured in surface runoff and shallow
groundwater as they moved through a small agricultural (cropland) watershed located in …

The influence of past land use on the present-day diversity of stream invertebrates and fish
was investigated by comparing watersheds with different land-use history. Whole watershed …

Riparian (streamside) vegetation may help control transport of sediments and chemicals to
stream channels. Studies of a coastal plain agricultural watershed showed that riparian …

Three streams in the Piedmont ecoregion of North Carolina were studied to evaluate the
effect of land use (forested, agricultural, urban) on water quality and aquatic biota. In …

The stream continuum concept suggests that the physical structure of the stream channel
coupled with the hydrological cycle and energy inputs results in a consistent pattern of …

This study investigates the spatial water quality pattern of seven stations located along the
main Langat River. Environmetric methods, namely, the hierarchical agglomerative cluster …

Water quality in streams, riv-ers, lakes, and coastal waters may change when wa-tersheds
are modified by alterations in vegetation, sediment balance, or fer-tilizer use after, for …

Data from 57 wetlands from around the world have been collated to investigate whether
wetlands affect the nutrient loading of waters draining through them; the majority of wetlands …
