Speaker: Dr. Kelly Aho, Boston University
Streams and rivers play important roles in carbon cycling. They act as connectors, biogeochemically linking the land, ocean, and atmosphere, and as reactors, supporting high rates of biogeochemical activity.
In this talk, Aho presents on processes controlling production and emission of greenhouse gases from these freshwater ecosystems, including how streams and rivers route terrestrially derived solutes to the atmosphere and how direct measurements of greenhouse gases can provide novel insights into existing ecological theory. This work has implications for not only understanding how freshwater ecosystems function biogeochemically, but also for predicting responses to climate change and potential climate feedbacks.
