Changes in abundance (log (# individuals)) per taxonomical macroinvertebrate class over time (# days since start).

<p>Insects form the largest class of colonist from the early onset of succession, maintaining equal levels of large abundance over time.</p

Morphological, physical and chemical characteristics of three re-connected stream trajectories in the Leuvenumse stream, the Netherlands.

<p>These parameters were measured 18 times from September 2014 until November 2016 within each trajectory, adjacent to the streambed surface where the invertebrate samples were taken.</p

Changes in functional trait composition (relative trait presence) over time of six different trait categories.

<p>Linear regressions of functional traits over time were calculated to test if specific functional traits were of increasing or decreasing importance during succession. Only taxa presence/absence data was considered in this case, multiplied with specific trait values and divided by the total number of species present per moment. Regression lines and coefficient are only shown for significant regressions. A: Feeding group, significant regressions: shredder, active filter feeder, passive filter feeder, B: Locomotion type, sig. regr.: burrowing, C: Dispersal mode, sig. regr.: aerial passive, aerial active, D: Rarity, sig. regr: semi-rare, E: Reproductive cycle, sig. regr: semivoltine, univoltine, F: r-K selection strategy, no sig. regr.</p

Changes in abundance over time (days since start) of four omnipresent taxa of insects, divided by order.

<p>A: Diptera, B: Ephemeroptera/Plecoptera, C: Trichoptera, D: Coleoptera.</p

Simplified map of the Leuvenumse stream catchment with the three reconnected former stream trajectories (indicated with red circles).

<p>The arrows show the direction of the water flow. The inset shows the most upstream location; the existing channel was blocked with sand (red dots), after which the water took its natural course through the former streambed (green dots).</p

Non-metric multidimensional scaling plot (NMDS; a rank-based approach to ordination, representing the pairwise dissimilarity between all cases).

<p>For both the species (A) and the trait-based (B) analysis, the data is fitted to two axes, using the Bray-Curtis distance metric.</p

Relative functional trait composition per season.

<p>Only significant different traits are shown. Different letters indicate significant differences between groups. Bold number indicates which season has the highest trait value.</p

Additive linear regression model results with season (autumn, winter, spring, summer) and time since start as predictors and relative trait occurrence as dependent variable.

<p>Only significant results are shown in this table.</p

Abundance data of the organism groups and raw values of abiotic response variables investigated (e.g. habitat diversity). These values were used to calculate Bray-Curtis dissimilarity indices for the restored and respective degraded sites
