*2.4. Statistics*

All data were analysed via the SPSS software v.20 package (StatSoft, Inc., Chicago, IL, USA) using a two-way Analysis of Variance (ANOVA). Tuckey's HSD test (*p* ≤ 0.05) was used for multiple comparisons of means. Data reported as percentage were subjected to an arcsin transformation prior to ANOVA as follow: Ø = arcsin(*p*/100)1/2. A heat map summarising all *L. siceraria* traits was performed via the online program clustvis (https://biit.cs.ut.ee/clustvis/, accessed on 14 September 2021) with a Euclidean distance as the similarity measure and hierarchical clustering with complete linkage.
