Distansescharella seguenzai Cipolla, 1921 (Bryozoa, Cheilostomata),nouvelles données morphologiques et écologiques tirées de spécimens fossiles (Mioc…
1989
The cribrimorph Distansescharella seguenzai Cipolla,,1921, described from the Pliocene of Sicily has been rediscovered in fossil deposits (Messinian of Western Algeria, and Lower Pliocene of Calabria, Southern Italy) and in Recent Mediterranean material (Straits of Gibraltar, Alboran Sea, Gulf of Tripoli). Its morphology is demonstrated by SEM study of living specimens. In spite of some differences with the type-species of Distansescharella D'Orbigny revealed by examination of its neotype, the generic status of D. seguenzai is confirmed. An ecological analysis of the Recent and fossil assemblages including D. seguenzai is made by considering the zoarial growth forms and the potential habita…

Macroalgal forest vs sea urchin barren: Patterns of macro-zoobenthic diversity in a large-scale Mediterranean study.
2019
Abstract The study aimed at contributing to the knowledge of alternative stable states by evaluating the differences of mobile and sessile macro-zoobenthic assemblages between sea urchin barrens and macroalgal forests in coastal Mediterranean systems considering a large spatial scale. Six sites (100 s km apart) were selected: Croatia, Montenegro, Sicily (Italy), Sardinia (Italy), Tuscany (Italy), and Balearic Islands (Spain). A total of 531 taxa, 404 mobile and 127 sessile macro-invertebrates were recorded. Overall, 496 and 201 taxa were found in macroalgal forests and in barrens, respectively. The results of this large-scale descriptive study have met the expectation of lower macrofauna co…
Biodiversity in canopy-forming algae: Structure and spatial variability of the Mediterranean Cystoseira assemblages
2018
Abstract In the Mediterranean Sea, Cystoseira species are the most important canopy-forming algae in shallow rocky bottoms, hosting high biodiverse sessile and mobile communities. A large-scale study has been carried out to investigate the structure of the Cystoseira-dominated assemblages at different spatial scales and to test the hypotheses that alpha and beta diversity of the assemblages, the abundance and the structure of epiphytic macroalgae, epilithic macroalgae, sessile macroinvertebrates and mobile macroinvertebrates associated to Cystoseira beds changed among scales. A hierarchical sampling design in a total of five sites across the Mediterranean Sea (Croatia, Montenegro, Sardinia,…
