| Title | Benthic-pelagic coupling in the Mar Piccolo of Taranto (Southern Italy, Mediterranean Sea): data for Resurrection Ecology |
| Abstract | Resting stages of planktonic organisms represent their adaptation to variable environments. In confined marine habitats, where variability of conditions is higher than in the open sea, the muddy bottoms host large amounts of plankton resting stages in the so called "marine cyst banks". The Mar Piccolo of Taranto was chosen to obtain an indication on how much the understanding of the marine cyst bank can facilitate the comprehension of plankton dynamics. The attempt was based on an integrated sampling approach with multiple devices and allowed us to identify 207 taxa/categories in the whole system (127 as active forms and 91 as resting stages). Planktonic populations can disappear completely from the water column, but the cyst assemblage is always present in the sediment. In fact, the marine cyst bank appeared as dedicating only 22% of its total abundance in benthic-pelagic exchanges. The benthic-pelagic coupling, however, was clearly depicted only for a minimal number of species. This result is attributable to the still scant knowledge of single life cycles. Apart from the identification difficulties (which cysts belongs to which species) different species probably adopt different strategies still to be clarified so impeding the formulation of a unique scheme for their co-existence. The unknown part of the resurrection ecology in Mar Piccolo was so important to represent di per se a result: the sediment side of the plankton functioning (the plankton dynamics observed from the benthos point of view) resulted useful and informative to perceive, in short times, the unexpressed complexity of the planktonic community in a confined area. |
