Effects of seaweed attributes on seagrass performance.

<p>Hedges <i>d</i> represent <i>d</i>_experiment for continuous data and <i>d</i>_cumulative ±95% CL for categorical data. Data were extracted from up to 59 experiments. Fig. B is based on 17 experiments that tested explicitly for abundance effects. Effects are here reported as Δ<i>d</i> = <i>d</i>_high−<i>d</i>_low; if Δ<i>d</i> is negative then high abundance cause larger negative effect than low abundance. Fig. G: coenocytic = single celled seaweed with modular growth of interconnected fronds.
