Stabilizing properties of a high-biomass benthic community in a fluctuating ecosystem

Abstract

The shallow Northern Adriatic Sea is subject to strong seasonal and short-time fluctuations in climatic parameters and production. A high-biomass benthic epifauna community on sublittoral soft bottoms with biomass values of 370±73 g wet weight m−2, which consists of almost 90% filter feeders provides a storage compartment. This storage compartment exerts a regulatory effect on the total system metabolism through controlling watercolumn biomass and converting it to macrofauna biomass with a lower respiration: biomass ratio. Special adaptations of the brittle starOphiothrix quinquemaculata, the dominant species, to strong and rapid changes in temperature and oxygen saturation are discussed.
