Alien species in the Mediterranean Sea by 2010. A contribution to the application of European Union's Marine Strategy Framework Directive (MSFD). Part I. Spatial distribution
The state-of-art on alien species in the Mediterranean Sea is presented, making distinctions among the four subregions defined in the EU Marine Strategy Framework Directive; the WMED hosts most invasive macrophytes, whereas the EMED has the lion’s share in polychaetes, crustaceans, molluscs and fish.
Alien species in the Mediterranean Sea by 2012. A contribution to the application of European Union’s Marine Strategy Framework Directive (MSFD). Part 2. Introduction trends and pathways
There is an increasing trend in new introductions via the Suez Canal and via shipping, while Lessepsian species decline westwards, while the reverse pattern is evident for ship-mediated species and for those introduced with aquaculture.
The Presence of the invasive Lionfish Pterois miles in the Mediterranean Sea
The new records highlight the arrival of new propagules of P. miles, more than two decades later, hinting to a future potential invasion of the Mediterranean Sea.
Reproduction in the dusky grouper from the southern Mediterranean
Demographic data and gonad histology confirmed that the dusky grouper Epinephelus marginatus is a protogynous hermaphrodite that follows a monandric pathway to sexual development. Females reached…

The molecular data support the view that Sparisoma originated approximately 14-35 million years ago, probably in the tropical western Atlantic, off Brazil; there have been at least four discrete bouts of cladogenesis within the genus, with the most recent one involving four events in both the east and the west Atlantic and across the Atlantic.
Tracking Signals of Change in Mediterranean Fish Diversity Based on Local Ecological Knowledge
The initial findings strongly suggest the northward expansion of termophilic species whose occurrence in the northern Mediterranean has only been noted previously by occasional records in the scientific literature.
Citizen science detects the undetected: the case of Abudefduf saxatilis from the Mediterranean Sea
A recreational diver reported the sighting of an unidentified and unfamiliar fish to an interactive web project ‘Seawatchers’, providing a small but concrete advancement towards early detection, which is important for management of biological invasions.
Range expansion of the common lionfish Pterois miles (Bennett, 1828) in the Mediterranean Sea: an unwanted new guest for Italian waters
A revision of the occurrences of the common lionfish Pterois miles (Bennett, 1828) in the Mediterranean Sea is provided, showing its rapid geographical expansion since 2012.
Fistularia commersonii in the Mediterranean Sea: invasion history and distribution modeling based on presence-only records
The results showed that colonization of the Mediterranean Sea proceeded in parallel along the southern and northern rim of the Basin at speeds that reached 1,000–1,500 km year−1 with a clear decrease in the rate of spread at the Sicily Strait, indicating abiotic factors of primary importance in shaping the distribution of this species in its invaded range.

The present study attempts to give timely information on the resource partitioning between the lessepsian migrant Siganus luridus and two ecological native analogues, Sarpa salpa and Sparisoma cretense, by conducting gut-contents analyses and trophic indices and multivariate analyses.
