Abstract
The techniques of collecting, extracting and counting of meiobenthos were applied to the study of juvenile macrobenthos in soft sediments. The vertical and horizontal distribution of juvenile and adult macrobenthos, and the influence of various factors (i.e. tidal level, granulometric composition of sediments, plant biomass, moisture, organic content of sediments, etc.) on their distribution have been investigated. Combinations of these factors differ in their influence on species, depending on the animals’ ontogenetic type (with or without pelagic larvae) and individual size. The spatial distributions of juveniles and adults were found to be different for macrobenthos with a pelagic stage in the life cycle. In contrast to this, juveniles and adults of species with direct development have more similar distribution patterns.
