The growth (basal area increment (BAI)) of shrubs in TSQs. From 2023 to 2024 Site A and 2024 to 2025 Site B. BA calculated from individual circumference and diameter d10 measurements and summed for all stems per shrub. Difference in BA from one ye...

The DBH of the trees of each TSQ were measured; these were converted to basal areas and the basal areas of all the trees within a TSQ were added, for a total tree basal area measurement for each TSQ. This serves as a measure of competition for the...

d13C and d18O isotopes were measured from the leaves of shrubs in TSQs. The leaves were collected, dried, milled into a powder, weighed and sent for stable isotope analyses in Jena (Max Planck Institute, Germany).

Hemispherical photos were taken from above the shrubs found in the TSQS in the BEF-China experiment. These were used to calculated the amount of light that penetrates through the tree canopy, to the understory shrubs. This openness was calculated,...
