Table 3 Results of multiple linear regression analyses of Abarenicola affinis abundance and biomass and habitat variables in seagrass and unvegetated habitat (all seasons combined, n = 60) (significant values in bold; \(R_{{_{\text{semipart}} }}^{ 2}\) = squared semi-partial correlation coefficient, indicating the proportion of variance explained by the inclusion of the predictor variable)

From: Lugworm (Abarenicola affinis) in seagrass and unvegetated habitats
