The impact of the Jessica oil-spill on intertidal macroinvertebrate communities was studied using a reference-impact design at three tidal levels at sites where oil deposits had been reported by a shoreline assessment team, and adjacent reference sites. Faunal relationships between the various sites did not show any clear pattern related to oil exposure at the time of sampling (4-11 months post-spill). Similarly, no significant differences associated with oiling were detected for total animal density nor species richness data, nor for the abundances of common taxa. We note that post-hoc studies such as this are limited by a failure to recognise different levels of oiling impacts at different sites (oiling-site interactions). Baseline information is critical if subtle effects of oiling are to be distinguished. © 2003 Elsevier Ltd. All rights reserved.
