Distribution of Coleoptera trait categories along the first (left) and second (right) RLQ axis.

<p>The right part of the axis 1 is associated with the Renner solution (RE) and the understorey (U), the left with the other two sampling solution (EG: ethylene glycol, CS: copper sulphate) and the canopy (C); the right part of the axis 2 is associated with the beech forests (FS: <i>Fagus sylvatica</i>), the left with the spruce forests (FS: <i>Picea abies</i>) (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0148247#pone.0148247.g003" target="_blank">Fig 3</a>). Horizontal boxplots display the weighted average position (points) of species trait categories in the Coleoptera community, including 25% and 75% quartiles and min and max values. Bottom dots with vertical lines are the weighted average positions of the species along the first RLQ-axis. See Table A in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0148247#pone.0148247.s006" target="_blank">S6 File</a> for species positions along the axes. Feeding guilds: c = carnivore, d = decomposer (excl. wood), dx = decomposer-wood, h = herbivore (excl. xylophage), m = mycetophagous-fungi, mm = mycetophagous-mould; Habitat guilds: df = fresh dead wood, do = old dead wood, ds = specific dead wood structures at living trees, e = eurytop, g = ground dweller, rnf = rotten substrate/nests/fungi (excl. wood), v = vegetation, wf = wood fungi.
