Predictors of total community uptake of Ulva-derived nitrogen.

DistLM marginal test results reporting the proportion of total community N uptake at the Austrovenus (n = 41) and Macomona (n = 29) sites and both sites combined (biomass normalized) explained by diversity indices and FG densities (see Tables 1 and 2 for abbreviation definitions). Marginal tests results describe how much variation each variable explains when considered alone, ignoring other variables. The (+) or (-) sign denote direction of the relationship, na = non-applicable predictor. Significant relationships are shown in Fig 4.
