Fig. 1.

Comparison of (A) radial growth, cambial pinning data and leaf onset during two seasons of four mature Terminalia superba trees in the Mayombe region of the Congo Basin, Central Africa (DR Congo) with (B) mean daily temperature, insolation as well as weekly precipitation for the measured period and (C) vapour pressure deficit (VPD) and relative humidity (RH). Gaps are missing data. In A, full lines are raw radius dendrometer data (three per tree), and each colour represents a tree (T1 green, T2 orange, T3 blue and T4 red). Circles at a given month are growth data derived from cambial pinnings. Vertical lines in A represent bud burst dates from the studied trees.
