Abstract
    More than 100 species belonging to plant and animal tars that are commonly observed in the intertidal zone were collected on both rocky and soft bottom shores of Brittany, France, to be analysed for their C-13/C-12 ratio. Plant material displayed a wide range of delta(13)C values (from -12 to -34 parts per thousand), with relatively distinct values among producer groups (Chlorophyce ae, Fucales, Laminariales, Rhodophyce ae seagrasses, plankton), and among strata of intertidal zonation. Animal delta(13)C range was narrower (-15 to -22 parts per thousand), and in general, values differed more between than within phyla or classes, according to the staple diet of organisms. A good correlation between the delta(13)C values of food and consumers was noted, together with a slight C-13- enrichment (approximate to 1 parts per thousand) with increasing trophic levels from suspension-feeders to predators.
