The vagile macro- and megafauna associated with the seagrass Cymodocea nodosa was studied over six months (May ? October) in the Northern Adriatic Sea (Pula/Croatia). Samples were taken at 2 and 5 m water depth at two bays (Valsaline, Valovine), which differ in exposure level to waves. The study aimed at determining whether there are differences in species occurrence and abundance depending on the water movement. Also, in both bays the seasonal growth cycle of the seagrass meadows was surveyed. To collect specimens, two sampling methods (standard-box and air-lifter, trawl sampling) were applied to contrast the efficiency of either method. As part of standard-box sampling, cut leaves were collected to infer the leaf area index. A total of 109 species were identified, whereof more species could be obtained by trawl sampling. In general, no taxonomic group could be exclusively ascribed to either bay/depth and therefore to a certain exposure level. Concerning the growth of Cymodocea nodosa, distinctively higher biomass was present at the more shielded sampling site (Valovine-Bay). Species, which dominated the structure of the fauna assemblages (SIMPER-test), were correlated with leaf surface area data. The available leaf area does not seem to affect the occurrence of species. Probably, suitable adjacent habitats (Cystoseira and/or Posidonia meadows) in either bay reduce the dependence of species on the Cymodocea meadows.
