✦ Synopsis

Large errors are made when laboratory measurements of the ingestion rate of hcrbivorous zooplankton are used t o estimate grazing in planktonic environments. The errors arise because the spatial heterogeneity in natural plankton distributions is greatcr than the Iiet,erogeneity present in laboratory experiments. Two probability models are developed for extrapolating laboratory measurements of ingestion to planktonic environments. Both models require sample statistics of the plankton distributions, and these are estimated from sampling studies of the small scale distribution of marine plankton. One model predicts laboratory measurements overestimate the ration obt,ained by an individual copepod by 30 yo. A second model predicts errors exceeding +50 % are possible when laboratory measurements arc used to estimate the grazing by a population of copepods.
