TL;DR: 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.

TL;DR: 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.

TL;DR: During the Bentart-2003 Cruise, three species of Lithodidae, Paralomis birsteini, Lithodes murrayi and Neolithodes capensis, were caught from 218 m to 1947 m, showing large and discontinuous distributions, which illustrate that many distribution patterns of Antarctic species are more an artefact of limited studies than representing actual distribution.

TL;DR: The analysis of monthly richness, equitability, diversity and k-dominance curves showed a stable and rich community despite the human influence and the proximity of the Guadalete River.
