Figure 2 in Marine biodiversity on the Algerian Continental Shelf (Mediterranean Sea)

Figure 2. West–east gradient of the macrofauna in the four sectors of the Algerian coast: sector 1 on the western Algerian coast (Ghazaouet, Oran and Arzew), sector 2 (Bou Ismail and Algiers) and sector 3 (Bejaia, Jijel and Skikda) in the centre, and sector 4 on the eastern Algerian coast (Annaba and El Kala). (A) Total richness of Polychaeta, Crustacea and Mollusca and (B) Total richness of Amphipoda, Decapoda and Bivalvia. We selected a similar sampling effort for this comparison (see Table 2). The total number of species was 850.
