Influence Of Current Velocity On Algal Responses To Nutrients In Poudre Watershed Streams

Sept. 4, 2018

Beck , Whitney S. 1 ; Poff , N. LeRoy 2 1 Colorado State University 2 Colorado State University Streamflow is a master variable that regulates biological communities in lotic ecosystems. Laboratory studies have shown that current velocity influences how algal communities respond to stream water nutrients. Faster velocities can...

Shifting Flow Paths: How Disturbance Drives Millennial Carbon Export

Sept. 4, 2018

Barnes , Rebecca T. 1 1 Environmental Science, Colorado College The flux of terrestrial C to rivers has increased relative to pre-industrial levels and a fraction of this flux is aged dissolved organic C (DOC). Once in rivers, C is stored in sediments, exported to the ocean, or (bio)chemically processed...
