| Abstract |
Structural and functional modifications induced by eutrophication of coastal ecosystems are examined from the point of view of planktonic microbial activity. lt is suggested that increasing input of organic matter tends to favour r-strategists among the heterotrophic organisms utilizing organic matter. This implies namely the prevalence of microorganisms food chains and the occurrence of special adaptations of microorganisms in their transport system for substrates. lt is also shown that a high bacterial heterotrophic activity is not necessary linked to a high rate of ammonium regeneration, depending on the C/N ratio of the organic matter used. Increasing flux of organic material depositing on the bottom results in the establishment of more reduced conditions in the sediments, which affects strongly both the form and the efficiency of benthic nitrogen recycling. |
