Height growth and biomass partitioning during secondary succession differ among forest light strata and successional guilds in a tropical rainforest

open access: yesOikos, Volume 2024, Issue 6, June 2024.
In closed‐canopy systems globally, plants exhibit intense competition for light, prioritizing vertical growth to attain elevated positions within the canopy. Light competition is especially intense in tropical rainforests because of their dense shaded stands, and during forest succession because of concomitant changes in vertical light profiles.
