Figure 1 Medrano et al (2026): Box-plots showing variation in average genome-wide DNA cytosine methylation (%) between ramets from the three study populations assigned to each of the three levels of herbivory treatment (control, insect and artificial herbivory). Each dot represents a ramet (N = 18, 27, and 18 for Spain, Italy and Poland, respectively). Lower and upper box boundaries are the 25th and 75th percentiles, respectively, line inside box the median, lower and upper error lines the 10th and 90th percentiles. Differences between the two herbivory levels and control undamaged plants were only statistically significant in CHH context

Photo of the experimental setup used to evaluate the comparative response to herbivory across the Brachypodium species complex. The picture was taken during the feeding experiment, in which the authors placed one locust on multiple lines of diploid Brachypodium distachyon, B. stacei, and B. hybridum allopolyploid. Locusts were allowed to feed for 48 h, after which damage and fitness were evaluated.

Figure 1 in Zhou et al. (2025): "Ophraella communa performance on the invasive plant Ambrosia artemisiifolia from nine populations and three regions with 0–9 and 17-year reassociation history with the specialist beetle O. communa (three reassociation groups) in a common garden experiment. (a) Weight of O. communa larvae, (b) pupae, (c) adults and (d) developmental duration of pre-adult stages on leaves of plants originating from A. artemisiifolia populations of the different reassociation groups. The P-value of ra (reassociation) represents the significance of time since reassociation (linear contrast among the three reassociation groups). In panel d, in addition to the linear contrast, two separate contrasts are indicated above the bars: 0 vs. >0 years reassociation (P < 0.001) and 9- vs. 17-year reassociation (P > 0.1). These contrasts are not shown for a–c where deviations from the linear contrast are very small. The error bars are ± SE (the same for the following figures). For each maternal line, 9–20 replicate bioassays were included and at least 100 beetles for each reassociation group, numbers in the bars represent replicates of beetles per reassociation group."
