Effects of urbanization on stream ecosystems (Spanish)

According to scientists from the U.S. Geological Survey there is no safe zone of development for the health of urban streams. In a new USGS audio podcast of a Spanish-language interview by Susan Soltero on Radio Walo (Humacao, Puerto Rico), scientists Ana Maria Garcia, Tom Cuffney, and Gerard McMahon note that even the early stages of urban development can negatively affect aquatic life in streams.
