简介
- Ecosystems are responding to broad‐scale changes in climate and other factors in complex ways. Two key changes occurring in many inland waterbodies are increasing temperatures and increasing terrestrial dissolved organic matter (tDOM) inputs. Due in part to tDOM inputs, inland waters play an important role in the global carbon cycle, with release of CO2 from these ecosystems a substantial portion of the combined carbon sinks of terrestrial ecosystems and the oceans.
- Ecosystem respiration (ER) is an important mechanism regulating CO2 in aquatic systems, and ER rates are temperature‐dependent. However, it is unknown how ER rates will change in the future because ER is sensitive to factors other than temperature, such as the concentration and source of organic matter. Theory posits that ER rates supported by refractory carbon compounds should exhibit a greater temperature dependence than ER …
