Título:  Natural fluctuations in a rocky subtidal community in the Oslo Fjord (Norway)
Autores:  Christie, H
Data:  1983
Ano:  1983
Resumo:  Natural variations were found to be governed by key species which structured the community. Of more than 60 species found, ca 10 were important in terms of abundance. Very few species exhibited stable abundance, and the community was dominated by annual cycles in populations mainly provided by seasonal settlement followed by predation and grazing, notably by Asterias rubens . Exclusion of this species lead to dramatic structral changes on artificial panels. Variation in abundance was analyzed using harmonic series plots. Models were produced for the most important species, and gave acceptable predictions when tested against the following year's data. Cyclic patterns appear annually, but suggestions long term trends were found to slightly alter this annual cyclic stability
