Figure 2

Abundance of P. nigra on different treatment panels used in this study. Abundance (mean ± SE 225 cm−2) data were pooled for each factor and all treatments. a) Recruitment pattern on different substrate types. b) Abundance of the ascidian on substrates indifferent colors. c) Abundance of the ascidian on panels submerged in vertical and horizontal orientation. d) Recruitment pattern on panels submerged in the shade and exposed to light
