Change in fish functional diversity and assembly rules in the course of tidal marsh restoration
Fig 7
Patterns of fish community assembly and monotonic trends in community-weighted means (CWMs) along the naturalness gradient of intertidal habitats.
The X-axis represents the gradient of intertidal habitat naturalness (DYK, dyked marshes; TRM, tidally restored marshes; NINT, natural intertidal habitats) and the Y-axis represents the CWM. The names of the functional traits were in Table 2. Trends related to the CWMs were corrected for salinity using Spearman semipartial correlation. Ascending and descending straight lines represent, respectively, significant positive and negative correlation between the CWMs and intertidal naturalness. Horizontal straight lines indicate lack of significant correlation. Grey areas correspond to parts of the gradient where environmental filtering (i.e., lower-than-expected trait range) was detected under the null model 2. Striped areas indicate higher-than-expected trait range. Double arrows indicate either trait convergence (convergent arrows) or divergence (divergent arrows). Grey arrows indicate both lower significavity (0.01 < p ≤ 0.05) and lower effect sizes (−0.5 < medianES < 0.5). Adapted from [14].
