Аннотация: More tree species can increase the carbon storage capacity of forests (here referred to as themore species hypothesis) through increased tree productivity and tree abundance resultingfrom complementarity, but they can also be the consequence of increased tree abundancethrough increased available energy (more individuals hypothesis). To test these two contrasting hypotheses, we analyse the most plausible pathways in the richness-abundancerelationship and its stability along global climatic gradients. We show that positive effect ofspecies richness on tree abundance only prevails in eight of the twenty-three forest regionsconsidered in this study. In the other forest regions, any benefit from having more species isjust as likely (9 regions) or even less likely (6 regions) than the effects of having moreindividuals. We demonstrate that diversity effects prevail in the most productive environments, and abundance effects become dominant towards the most limiting conditions. Thesefindings can contribute to refining cost-effective mitigation strategies based on fosteringcarbon storage through increased tree diversity. Specifically, in less productive environments,mitigation measures should promote abundance of locally adapted and stress tolerant treespecies instead of increasing species richness.
