ASSESSMENT OF THE RATE OF CHANGE OF THE BIOCENOSIS OF THE INNER PUCK BAY
Journal Title: Biuletyn Instytutu Morskiego - Year 1998, Vol 25, Issue 2
Abstract
For decades, the biocenosis of the inner Puck Bay has been undergoing transformation, which probably at the break of the 60ties and 70ties took an ecologically disadvantageous turn. The negative processes which appeared at that time resulted both from eutrophication and anthropopression. Withdrawal of many animal and plant species was observed. The freed ecological niches were taken up by species which formerly appeared in small numbers. Significant changes of the biocenosis structure took place. In this paper, basing on the formula for the half-period of change, the rate of change of selected components of the ecological formations is calculated. Obtained results may allow to evaluate the processes disrupting the structure of biocenosis under the influence of long term eutrophication and anthropopression.
