Neighbourhood‐mediated shifts in tree biomass allocation drive overyielding in tropical species mixtures

Summary Variations in crown forms promote canopy space‐use and productivity in mixed‐species forests. However, we have a limited understanding on how this response is mediated by changes in within‐tree biomass allocation. Here, we explored the role of changes in tree allometry, biomass allocation and architecture in shaping diversity–productivity relationships (DPRs) in the oldest tropical tree diversity experiment. We conducted whole‐tree...
