Researchers Find a Keystone Nutrient Recycler in Streams
June 27, 2011
Researchers from the University of Georgia Odum School of Ecology have found that certain neotropical stream ecosystems rely almost entirely on a single fish species known as the banded tetra for the critical nutrient phosphorus. In a paper recently published in the journal Ecology, the researchers, led by Gaston E. "Chip" Small, explain why this particular species plays such a crucial role--and why these stream systems are vulnerable as a result.
