Special Feature: Urban Aquatic Ecosystems

Collection launched: 20 Jan 2015

Jennifer L. Morse, Principal Investigator, Portland State University

New approaches to understanding urban aquatic ecosystems
Aquatic ecosystems in urban environments are highly modified by human activity, engineering, and design. These systems are critical in delivering ecosystem services to urban residents, who comprise over 80% of the US population. Therefore, understanding the ecological functioning of these systems and integrating research across urban areas is of great importance. This Special Feature on Urban Aquatic Ecosystems was invited following a Special Session featuring these authors at the 2014 Joint Aquatic Sciences Meeting. The scope of research topics ranged from hydrology to microbial ecology and encompassed a variety of regions and types of urban aquatic ecosystems, including buried streams, constructed wetlands, and urban rivers. We aimed to bring together studies of urban aquatic ecosystems that focused on comparative and synthesis approaches.

Nine Mile Run Culvert
Only 16% of Nine Mile Run's streams still flow above ground, the rest of Nine Mile Run's streams are enclosed in storm sewers under city streets.
Poor Water Quality
High nutrient levels and algal blooms reduce the amount of dissolved oxygen available to aquatic life
Combined Sewer Outfall in Minneapolis
Many older cities have combined sewer systems that discharge raw sewage mixed with stormwater directly into urban rivers and streams
Concrete Lined Stream Channel
The banks of many urban streams are hardened with concrete to prevent erosion and convey water quickly out of the city
Nine Mile Run
is an urban stream in Pittsburgh, PA that is faced with poor water quality from polluted runoff and combined sewer overflows
