Table 1.

Variation partitioning of the adipogenic activity of R. groenlandicum leaf extracts explained by the content in biologically active compounds (compounds) and the effect of bioclimatic variables (environment). Fraction [a] corresponds to the unique contribution of compounds once the environment has been taken into account, whereas fraction [c] represents the reverse. Fraction [b] represents the shared portion, or overlap, between the effect of compounds and environment. The variation (R _adj ²) of each fraction is represented in Figure 6. Asterisk (∗) indicates significant fractions at α = 0.05.
