Fig. 5From: Comparing biodiversity effects among ecosystem engineers of contrasting strength: macrofauna diversity in Zostera noltii and Spartina anglica vegetationsMean biomass (g AFDW m−2 ± SE) observed for each feeding group at the four different areas. Closed bars endofauna, open bars epifauna. Endofaunal and epifaunal biomasses were analyzed separately for significant differences between the four habitats. Letters indicate significant differences among habits using a posteriori Tukey HSD testsBack to article page
