Falter, M. Atkinson, D. Schar, R. Lowe, S. Monismith] Rates of net community carbon production (mmol C m−2h−1) were measured continuously in an algal-dominated reef flat community on the Kaneohe Bay barrier reef, Hawaii, for 12days at the end of October 2006. The weather became increasingly cloudy during the last 5days of measurements, resulting in a sevenfold decline in daily incident light (28-4 Ein m−2 d−1). In response, gross primary production (P) for the reef flat community also decreased sevenfold, varying linearly with light (r 2=0.92, n=12). Community respiration (R) decreased fivefold over this same period and was highly correlated with changes in P (r 2=0.84, n=12). We reason that this short-term coherence between P and R indicates that most of the carbon fixed during this period was rapidly metabolized via plant respiration. We further conclude that the dominance of autotrophic respiration under general conditions of nutrient-limited growth can explain much of the balance between P and R that is commonly observed in shallow reef communities.
