Figure 13 in Tanaidacea (Crustacea: Peracarida) of the North-east Atlantic: the genera Leptognathioides and Portaratrum of the 'Atlantic Margin'

Figure 13. Patterns of community contribution and relative abundance in Leptognathioides polita: (A) regional contribution comparing species rank (y-axis species rank by abundance, standardised) to relative abundance by region (x-axis percentage contribution to total number of tanaidacean individuals); vertical and horizontal lines indicate 25% level, below which 'rarity' may be invoked; (B) distribution of individual sample frequencies; vertical bars indicate % contribution to total number of tanaidaceans in sample.
