Fifty years of hyporheic zone research have shown the important role played by the
hyporheic zone as an interface between groundwater and surface waters. However, it is only …

The concentration of materials and energy within cities is an inevitable consequence of
dense populations and their per capita requirements for food, fiber, and fuel. As the world …

Hydrologic connections can link hillslopes to channel networks, streams to lakes, subsurface
to surface, land to atmosphere, terrestrial to aquatic, and upstream to downstream. These …

Managing water resources is one of the most pressing challenges of our times-fundamental
to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse …

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 …

Over the past 3 decades, nutrient spiraling has become a unifying paradigm for stream
biogeochemical research. This paper presents (1) a quantitative synthesis of the nutrient …

A regression model (RivR-N) was developed that predicts the proportion of N removed from
streams and reservoirs as an inverse function of the water displacement time of the water …

Streams and rivers regulate nitrogen transport (N) to downstream ecosystems. Rates of N
uptake can be high in streams, but controls on the variation in uptake rates of N among …

This paper provides a global synthesis of reactive nitrogen (Nr) loading to the continental
landmass and subsequent riverine nitrogen fluxes under a gradient of anthropogenic …

Individual animal species can impact ecosystem processes, but few exotic invaders have
demonstrated ecosystem‐scale impacts, even when population sizes are large. We …
