Abstract: I will show the results of a project on the global ecology and biogeography of reef fishes. The project allowed for the compilation of two extensive global databases, the first on the geographical distribution of 6,316 reef fishes and the second comprising abundance information from about 10,000 transects across the world. This information was used to conduct three main studies which include the quantitative delineation of biogeographical regions for reef fishes at a global scale, the development of a global predictive model for species richness, and finally the biogeographical analysis of functional structure and redundancy of species assemblages. Further our global databases are presently being used during my visit at JCU for the analysis of global scale assembly rules in reef fish assemblages. Overall, our results allowed for the definition of several biogeographical units, consisting in three realms, 6 regions and 11 provinces. Despite large differences among these biogeographical units in term of richness, mainly related to reef area, the functional diversity of assemblages is surprisingly stable across the entire tropical world. However, such high functional diversity does not result in lower vulnerability to species loss as even in highly diverse assemblages, such as those of the Indo-Australian Archipelago, there may be limited functional redundancy.

Biography: Following a PhD in Marine Environmental Science at Genoa University, Italy, Dr Parravicini worked with Fiorenza Micheli in Stanford University, before taking on a post-doc position with IRD based in France. He is currently working with a large international group on reef fish biogeography including Michel Kulbicki (IRD), David Mouillot (Montpellier) and David Bellwood (JCU).
