Stades initiaux de colonisation de substrats durs dans la Baie-des-Chaleurs,Québec

In the first settlement stages on immersed glass slides, the degree of colonization by an organism is determined by the duration as well as the season of immersion. Therefore, in the first period of settlement no ecological succession is obvious, but different ecological groups are favoured according to the prevailing environmental conditions. The development of these groups is regulated by well-defined physico-chemical conditions. First settlement stages would therefore play only a minor role in the subsequent development of a colony and attainment of its and final steady state.
