- Abstract
Two ecologically and morphologically distinct forms of Furcellaria lumbricalis and loose form of Coccotylus truncatus were experimentally tested to obtain information on the growth rates and influence of the habitat depth on their eco-physiological activity. Incubations were carried out in the area inhabited by a loose F. lumbricalis– C. truncatus community in Kassari Bay of the West-Estonian Archipelago Sea, the NE Baltic Sea. During the incubation period (20.04–21.10.2002) loose forms of F. lumbricalis and C. truncatus showed similar dynamics of both growth rate of biomass and primary production while attached form of F.␣ lumbricalis had, as a rule, significantly lower growth rate and primary production values. The highest eco-physiological activity was recorded from the shallowest incubation depth (4 m) for all three algal forms. All three tested algal forms had similar pattern of growth during the incubation period – highest growth rates were detected in spring and early summer while during the rest of the incubation period algal biomass was in a steady state when production balanced degradation processes.
