Abstract Responses of estuarine community structure, respiration and production to added heat, sewage and their combination were investigated. Plastic pools containing transplanted ecosystems from South Creek Estuary, N. C. were used. Temperature replication was achieved. Thermal treatment increased nutrient regeneration rates, yielding slightly higher algal biomass; although, seasonal differences were more significant. Sewage addition substantially increased ammonia levels, particularly during the winter. Community metabolism responded positively to thermal treatment, but not to sewage treatment. Temperature had very little effect on phytoplankton composition during the spring. A flow-through experiment was conducted to test more realistic estuarine conditions. Results were substantially the same as obtained under quiescent conditions.
