Thanks to the analysis of the sponge siliceous spicules present in ancients sediments trapped into coralligenous bio-concretions, the sponge biodiversity had been studied in the last 6000 years in the Porto Cesareo MPA (Ionian Sea). The sponge richness trend, in terms of presence of genera, showed a long stable period (among 5800 and 4500 YBP) of high biodiversity that overlapped the Holocene Climatic Optimum.

Abstract
Thanks to the analysis of the sponge siliceous spicules present in ancients sediments trapped into coralligenous bio-concretions, the sponge biodiversity had been studied in the last 6000 years in the Porto Cesareo MPA (Ionian Sea). The sponge richness trend, in terms of presence of genera, showed a long stable period (among 5800 and 4500 YBP) of high biodiversity that overlapped the Holocene Climatic Optimum.
