Simulation of REVEALS estimates (proportion in log scale).

<p><i>Alnus-Capinus</i>, <i>Picea</i>-Cerealia and <i>Abies</i> delimit three groups of terminal velocities of pollen: slow, medium and fast, which also represent the pattern of the rest of taxa not plotted here. Arrows show the change of estimates from control (full line) to scenario (dashed line); for details, see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0100117#pone-0100117-t002" target="_blank">Table 2</a>. (A) Simulation A: Increasing radius of the sedimentation basin under two wind speed velocities (B) Simulation B: Increasing radius of the area of the background pollen under two wind speed velocities. (C) Simulation C: Fixed versus increasing radius of the sedimentation basin of the second site. (D) Simulation D: Increasing pollen counts of <i>Alnus</i> and <i>Picea</i> under two radii of the sedimentation basin. The reference setting common to all control simulations is marked on the secondary horizontal axis by “REF”.
