“…In the study area, information on coastal zooplankton is scattered (Marano et al, 1974;Belmonte, 1988;Coen & Gravina, 1992 for mesozooplankton; Belmonte et al, 1995;Rubino et al, 1997 for cyst banks), and only two reports are available concerning the phytoplankton of the Otranto Channel (Caroppo et al, 1999a, b). This paper considers the plankton composition along the Salento Peninsula (Apulia, South-Eastern Italy), adopting an integrated water/sediments approach over a wide scale.…”

An oceanographic survey was carried out along the Salento Peninsula in March 2000. Resting stages of plankton were searched for in coastal sediments to study the microplankton composition in addition to the classical analysis of active stages in the water column. A total of 215 taxa were recognised, 149 as active stages in the water column and 74 as resting stages in the sediments. Cysts were widely distributed and at Brindisi and Alimini their abundance was higher than elsewhere. A general trend was observed with resting stage abundance, species richness and diversity in the sediments: all three decreased with distance from the coast. The integrated water/sediments approach used in this study allowed us to collect 37 species (mainly as resting stages) new for the studied area.

“…Despite this, the sediments of the Mar Piccolo host a well-structured holobenthic (foraminifera and ostracods) and merobenthic (the resting stages of plankton) community. The latter has already been well investigated during the last several years (Rubino et al 1996(Rubino et al , 1998(Rubino et al , 2009, but the present study has been carried out on a large number of stations in the two sub-basins and it is the first one ever including foraminifera and ostracods, aiming to obtain further knowledge to be applied in future studies on environmental quality.…”

Benthic foraminifera and ostracods, and resting stages (cysts) of plankton were analysed from surface sediment samples collected at 20 stations in the Mar Piccolo of Taranto (Ionian Sea, Mediterranean), with the aim to advance our knowledge on the biodiversity and ecological features of confined marine areas and to upgrade the autoecology of the species, and to have a more detailed and complete information to be applied as the baseline in future studies on environmental quality. In order to better assess the spatial distribution of the holobenthic and merobenthic species, we conceived a simple method of spatial analysis, based on all the identified taxa of foraminifera, ostracods and plankton cysts. Five groups were established on the basis of the number of sites per sub-basin where each taxon was registered, and this allowed us to recognise the preferential patterns of distribution for 150 species. The good correspondence between the results of the spatial analysis and those obtained from the analysis of the communities and the uni-and multivariate statistics showed a clear difference between the two sub-basins of the Mar Piccolo of Taranto.

“…This complex frame of continuous replenishment/impoverishment of the cyst bank in coastal sediments needs to be precisely quantified to allow us a better understanding of its consequences for plankton community dynamics (the so-called "Resurrection Ecology" of Kerfoot and Weider, [8]) (Figure 1). The first studies on the marine cyst bank of the Mar Piccolo [4,23] represented the starting attempts to evaluate the role of cyst banks in the plankton dynamics of that site. The first studies on the marine cyst bank of the Mar Piccolo [4,23] represented the starting attempts to evaluate the role of cyst banks in the plankton dynamics of that site.…”

Resting stages represent the answer for species to the variability of environmental conditions. In confined marine habitats, variability of conditions is high, and bottoms host plankton resting stages in the so-called “marine cyst banks”. The Mar Piccolo of Taranto was chosen as a pilot site in which to investigate how marine cyst banks and plankton affect each other in the living part of the benthic–pelagic coupling. The attempt was based on the use of multiple devices for integrated sampling of benthic and pelagic stages and allowed us to identify 207 taxa/categories in the whole system (127 as active forms, 91 as resting stages). The sediments added 80 taxa to the plankton list obtained only from the water column, thus confirming the importance of this kind of approach in perceiving the actual diversity of the studied site. The sediment cyst bank involved 0.15–1.00% of its content in daily benthic-pelagic exchanges, in terms of cyst germination and import, respectively. In addition, the cyst production, which was higher than the cyst germination, is responsible for the existence of a permanent biological reservoir in the sediments. The benthic-pelagic coupling, however, was completely depicted in the present investigation only for seven taxa. This result is due to the still scant knowledge of the life cycles and life histories of single species. Apart from the identification difficulties that still have to be clarified (which cysts belong to which species), the cycle presence/absence is also characterized by the diversification of strategies adopted by each species. The observation of plankton dynamics from the benthos point of view was useful and informative, unveiling a huge assemblage of resting forms in the sediments only minimally affected by cyst import/export, because it is more devoted to a storing role over long periods. Consequently, the continuation of life cycle studies appears necessary to understand the diversity of strategies adopted by the majority of plankton species.
