From: Decoding the spread of non-indigenous fishes in the Mediterranean Sea
Spatial representation of the progressive movement (momenta; black circles: tx) of the dominant regions of introductions in the Mediterranean Sea (blue). The progressive trajectory (dotted line) was carried out based on the alignment of the spatial centroids for each successive momentum. The trajectory denotes the connection between the inferred entrance (Suez Canal; Entry Point) to the tenth (t10) successive momentum, while the Mediterranean has been classified in the four MSFD regions (EMED; CMED; ADRIA; WMED).
