  abstract = {{R}esearchers often use metabolic measurements in the field over narrow time periods to estimate an organism's metabolism over large time scales. {H}ere, we measured in situ respiration, calcification and excretion rates of the tropical gastropod {T}ectus niloticus {L}. through benthic chamber experiments. {O}ur samples spanned a 21 h time frame and were taken during both the warm and cool seasons. {W}e assessed diel and seasonal variability in metabolic rates, as well as the effect of individual size and the contribution of shell epi-and endobionts. {O}ur results show that metabolic rates vary through time at both diel and seasonal scales, as measured fluxes for respiration and calcification were significantly higher at night during the warm season. {T}his nocturnal pattern was not significant in the cool season. {S}ize effects were significant with higher respiration and calcification rates for small individuals regardless of the season, although the difference tended to be more pronounced in the warm season. {W}e also found that shell epi-and endobionts made an important contribution to respiration, as 40 and up to 100% of total measured fluxes for night and day, respectively, could be attributed to the shell community. {M}ore importantly, the direction of the measured flux was occasionally opposite that of the individual trochus, highlighting that the contribution of shell epi-and endobionts must be accounted for in order to achieve an accurate understanding of individual metabolism. {L}astly, depending on the time of day and season when measurements are taken, ignoring diel or seasonal variations in metabolic rates could result in important under-or overestimation of the contributions of gastropods to carbon and calcium carbonate fluxes in coastal ecosystems.},
