Preliminary studies on the reproduction and population dynamics of , and , (Mollusca, Gastropoda) o as size increases, indicating a certain synchrony..The new recruits of . are detected on the bare rock by September to November and are recognizable through their first year. Due to the amplitude of the breeding period and differing growth rates size distribution within an age class is wide. Size c

Comparative trends and ecological patterns of rocky subtidal communities in the Swedish and Norwegiucturing factors, as well as key species, appeared to be largely the same over the geographic range studied. By comparing all of our results (mostly based on already published data), recruitment and predation were found to be the most important locally organizing factors. Recruitment strategies and

Temporal changes of community structure and biomass in two subtidal macroinfaunal assemblages in Laan similarity of every sample with the following ones is relatively high and stable, and diversity (H’) and evenness (J’) fluctuations are small. However, in the . station the community structure has changed drastically after dredging operations ended as a result of the recolonization and further st

The generalization of these methods in benthic studies should allow the comparison in space and time of the scale of the physical factors responsible for the observed phenomena.
