Description
Cameron Callbeck and co-authors track how a Swiss lake removes nitrogen through a microbial process called denitrification. Their 2026 study links the process to seasons. Warming is expected to lengthen the summer period when lake layers stay apart and shorten winter mixing, which may change how nitrogen cycles move.
Using tracer tests, molecular tools, and flux measures, the team found the process was most active in the winter mixed period. A group of microbes that break down chitin seems to play a key part. In a lake model, a worst-case warming path cut mixing by about twenty-seven days and lowered nitrogen removal, sending more nitrogen downstream.
