“…Details on locality and collection time of the samples are shown in Table 1. In the multivariate statistical analysis, results obtained in the present studies were compared with all remaining genetic lineages from previous research on A. pinguis [34,35]. As in previous studies, a small amount of biological material that could be collected for individual genetic lineages of A. pinguis from a given habitat in different vegetation seasons was determined using the HS-SPME technique.…”

“…These data facilitate comparisons of the current results with those previously described. To determine whether the chemical compounds can act as chemotaxonomic markers permitting the determination of all cryptic species of A. pinguis, the data obtained for samples in current studies (C1, C2, E1, E2, G, H, I) were compared in multivariate statistical analyses with data on the remaining genetic lineages of A. pinguis previously published [35]. Two classification methods were used: principal component analysis (PCA) and cluster analysis (CA).…”

“…The percentage of explained variance (R 2 X) was 81.4% for PC1, 6.2% for PC2, and 4.3% for PC3, and the predictive ability (Q 2 ) was 36.7%, 16.7%, and 19.9%, respectively. Species in this study were compared with the remaining species of A. pinguis examined in a previous study [35].…”

“…Differences in the composition and amount of volatile compounds were also found for evolutionary lineages distinguished based on molecular studies of species A (A1, A2, A3) and species B (B1, B2, B3). Thus, there is a close correlation between the chemical composition of the plant and its genotype [35].…”

Aneura pinguis (L.) Dumort. is a representative of the simple thalloid liverworts, one of the three main types of liverwort gametophytes. According to classical taxonomy, A. pinguis represents one morphologically variable species; however, genetic data reveal that this species is a complex consisting of 10 cryptic species (named by letters from A to J), of which four are further subdivided into two or three evolutionary lineages. The objective of this work was to develop an efficient method for the characterisation of plant material using marker compounds. The volatile chemical constituents of cryptic species within the liverwort A. pinguis were analysed by GC-MS. The compounds were isolated from plant material using the HS-SPME technique. Of the 66 compounds examined, 40 were identified. Of these 40 compounds, nine were selected for use as marker compounds of individual cryptic species of A. pinguis. A guide was then developed that clarified how these markers could be used for the rapid identification of the genetic lineages of A. pinguis. Multivariate statistical analyses (principal component and cluster analysis) revealed that the chemical compounds in A. pinguis made it possible to distinguish individual cryptic species (including genetic lineages), with the exception of cryptic species G and H. The classification of samples based on the volatile compounds by cluster analysis reflected phylogenetic relationships between cryptic species and genetic lineages of A. pinguis revealed based on molecular data.
