From: Effects of multiple stressors on river biofilms depend on the time scale

Changes in production-respiration ratios for river biofilms after short and long-term exposure to the different treatments (hydrological stress; H, warming; W, pesticides; P, H:P, W:H, W:P, W:H:P) and control biofilms (C). Bars represent averaged values (n = 3), error bars represent standard errors.
