Abstract In situ measurements of community respiration were made at two stations in Castle Harbor, Bermuda, during April and May, 1971. Total community respiration was 20.67 and 19.11 ml O2 m-2 h-1 at Stations 1 and 2, respectively, in April. In May, respiration increased with water temperature to 26.99 and 24.56 ml O2 m-2 h-1. Significant differences (P〈0.05) existed between stations and sampling periods. Bacterial respiration was estimated from sediment treatment with streptomycin-SO4. Values ranged from 7.71 to 8.72 ml O2 m-2 h-1 in April and May, respectively. No significant difference existed between sampling periods or stations. No detectable chemical O2 demand of the sediment, determined by a formalin treatment, was found. Total community respiration was further compartmentalized into macrofaunal, meiofaunal, and microfaunal-microfloral components. Both the macrofaunal and meiofaunal respiration was negligible compared to that estimated for the microfaunal-microfloral component.
