Summary: In any ecosystem, the complex relations from species to populations and community levels require the long term investigations. In frames of present project, special attention was paid to short term qualitative and quantitative variations in biota, repopulation and chemical composition of organisms controlled by environmental factors. Results provided insight and explanation in the north Adriatic bottom communities dynamics. Papers on results are published in part, several manuscripts are in print, and others are in preparation. The divers activities resulted in photo exibition on representative species noted in north Adriatic bottom communities.

Keywords: Dinamics, benthic communities, flora, fauna, chemical composition, mortality, population recivery, Adriatic Sea

Research goals: Recent benthic investigations on qualitative and quantitative composition and seasonal changes in bottom communities indicated several fundamental problems which desire more attention forbetter understanding of stressed situations repeated frequently in the north Adriatic Sea. Physical and chemical parameters can point on environmental changes, but bottom communities, due to their relative stability, are better indicators of sea perturbations reflected for several years. The nort Adriatic Sea,a semi closed and shallow water region, is ideal area for monitoring changes caused by climatic and anthropogenous agents.Therefore, by the multidisciplinary approach the following short term studies were proposed: the qualitative and quantitative composition of various bottom communities in stressed coastal and offshore zones in the west Istrian area, the species and community behavior affected by stress con conditions, especially lack of oxygen; the species and community recoveries after stress events, the recruitment rates of organisms settled on natural and artificial substrata, and in the sediment cores; the chemical and mineral composition of selected seaweeds and bivalve shells with regard to the bottom type and manner of life, the sexual cycle related to chemical variations in soft body parts of two commercial shellfish species.
