Spatio-temporal analysis of biodiversity indices estimated in the bathyal demersal species assemblages of the Ionian Sea has been performed. Data were collected during 16 trawl surveys carried out from 1995 to 2010 as part of the international MEDITS project funded by EC. In the Apulian sector a significant increase of species richness and a significant decrease of evenness have been detected. In the Southern Calabrian sector a significant decrease of evenness has been detected while a positive trend has been found for the Simpson index. GAM’s have then been applied to explain the dependence of the indices in terms of time and space.

Abstract

Spatio-temporal analysis of biodiversity indices estimated in the bathyal demersal species assemblages of the Ionian Sea has been performed. Data were collected during 16 trawl surveys carried out from 1995 to 2010 as part of the international MEDITS project funded by EC. In the Apulian sector a significant increase of species richness and a significant decrease of evenness have been detected. In the Southern Calabrian sector a significant decrease of evenness has been detected while a positive trend has been found for the Simpson index. GAM’s have then been applied to explain the dependence of the indices in terms of time and space.
