Streams in the Urban Landscape
The world’s population is concentrated in urban areas. This change in demography has brought landscape transformations that have a number of documented effects on stream ecosystems. The most
Standards for ecologically successful river restoration
Summary 1. Increasingly, river managers are turning from hard engineering solutions to ecologically based restoration activities in order to improve degraded waterways. River restoration projects aim
Synthesizing U.S. River Restoration Efforts
The authors of this Policy Forum developed a comprehensive database of >37,000 river restoration projects across the United States. Such projects have increased exponentially over the past decade
Control of Nitrogen Export from Watersheds by Headwater Streams
A comparative 15N-tracer study of nitrogen dynamics in headwater streams from biomes throughout North America demonstrates that streams exert control over nutrient exports to rivers, lakes, and
Stream ecosystem function in urbanizing landscapes
Abstract Ecologists have described an urban stream syndrome with attributes such as elevated nutrients and contaminants, increased hydrologic flashiness, and altered biotic assemblages. Ecosystem
Stream denitrification across biomes and its response to anthropogenic nitrate loading
It is demonstrated that excess nitrate in streams elicits a disproportionate increase in the fraction of nitrate that is exported to receiving waters and reduces the relative role of small versus large streams as nitrate sinks.
Multiple Trophic Levels of a Forest Stream Linked to Terrestrial Litter Inputs
The importance of terrestrial-aquatic linkages was evaluated by a large-scale, 3-year exclusion of terrestrial leaf litter inputs to a forest stream, demonstrating that different food webs exist in habitats of different geomorphology.
The Contribution of Headwater Streams to Biodiversity in River Networks 1
Abstract:  The diversity of life in headwater streams (intermittent, first and second order) contributes to the biodiversity of a river system and its riparian network. Small streams differ widely in
We examined the importance of terrestrial detrital inputs to secondary productivity of a headwater stream. Following a year of pretreatment studies on two headwater streams, we excluded terrestrial
Restoring Rivers One Reach at a Time: Results from a Survey of U.S. River Restoration Practitioners
Despite expenditures of more than 1 billion dollars annually, there is little information available about project motivations, actions, and results for the vast majority of river restoration efforts.
