Abstract :
Invasive species are threatening the biodiversity of the marine ecosystems! There are a lot of newspaper articles about the presence of non-native species in the Mediterranean. But what is really happening ?
What are these non-native species? How can we distinguish the various kinds of species? How do these species manage to penetrate into the Mediterranean? What impact do these species have on the Mediterranean marine environment? How should we act to restrict the introduction of these species? What is the future of the Mediterranean in the face of these new arrivals?
