Summary barplot of nematode abundance, Richness, Hill´s diversity (Hill´s 1), Hill´s reciprocal of D (Simpson´s dominance index) (Hill´s 2) and Hill´s evenness diversity indexes derived from results of <i>Xiphinema</i> spp. identification in 385 sampling sites of olives orchards (Fig 1) grouped by olive type (wild and cultivated olive) and <i>X</i>. <i>americanum-</i>group and <i>X</i>. non-<i>americanum-</i>group species.

<p>Error bars indicate the standard error of the mean. Significance = F probability of main effects in ANOVA, according to Tukey´s test [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0165412#pone.0165412.ref049" target="_blank">49</a>] for <i>P <</i> 0.05.
