For non-clonal species, the most responsive species to changes in
environmental and insularity conditions were Carlina ,Helianthemum and Lychnis , whereas Silene andThymus responded weakly. The variance explained by the single
predictors in the OLSs for the most important relationships ranged
between 15% and 87% (Table 4). The most responsive traits across
species were radial growth and storage tissue. Consistent
trait-environment patterns could be identified only across a reduced
number of species (i.e. 2 or 3 out of 8); the majority of
trait-environment links was highly species-specific, either unique to
some species or sometimes contrasting within the same single
trait-single predictor relationship (Table 4).
TABLE 4 Results of the OLS regressions for the eight non-clonal
species. Sign (arrow direction), significance (p-value: ** ≤ 0.01; * ≤
0.05; . ≤ 0.1) and strength (R2 values) of single
trait-single predictor links are reported. Only the most important
relationships (based on the model coefficient, 95% confidence interval,
significance, R2) are indicated – refer to
