“…This limitation restricted us in drawing general conclusions about the AGC in subtropical Brazilian mixed forests, since other protected (e.g., strict protected areas) and non-protected forests (e.g., forests in a rural matrix) may contribute differently to the conservation of diversity and the maintenance of carbon stocks [24,51,52]. Despite these limitations, our results agree with the ndings from other large-scale studies of Brazilian subtropical forests, where (taxonomic, functional, and phylogenetic) diversity was determined as not being signi cantly related to net carbon changes [14] or carbon stocks [26,27].…”

“…Although the diversity-biomass relationship is common in several Brazilian forest types [23,24,25], it is less evident in subtropical forests [26], and especially mixed forests, likely due to the dominance of A. angustifolia in all successional stages [27]. In addition, the carbon storage capacity and its correlation with biodiversity in subtropical Brazilian Atlantic Forests is information necessary to future conservation efforts that remains poorly understood [14].…”

Background Understanding the drivers of variations in carbon stocks is essential for developing the effective management strategies that contribute to mitigating climate change. Although a positive relationship between biodiversity and the aboveground carbon (AGC) has been widely reported for various Brazilian forest types, representing a win–win scenario for climate change mitigation, this association has not been commonly found in Brazilian subtropical forests. Therefore, in the present study, we aimed to evaluate the effects of Araucaria angustifolia populations, stand structure and species diversity in shaping AGC stocks in Brazilian subtropical mixed forests. We hypothesized that the effects on the AGC of stand structure and diversity would be mediated by A. angustifolia. We also evaluated the expectation of higher carbon stocks in protected forests as a result of their positive correlation with biodiversity conservation. Results We found that stand structure, followed by A. angustifolia population, played the most important role in shaping the AGC stock. Our hypothesis was partially confirmed, the direct and indirect effects of A. angustifolia on stand structure being found to have shaped the AGC. Similarly, our expectation was partially supported, with the higher AGC in the protected area being related not to diversity, but rather to the presence of larger trees, denser stands, and a greater abundance of A. angustifolia. Conclusion Although the win–win strategy between diversity conservation and carbon storage is not a peculiarity of Araucaria forests, we highlight the potential of these forests as a nature-based climate solution, maintaining high levels of carbon storage in harmony with the provision of keystone resources.

“…Wood density also varies with the successional stage of forests 25 and is influenced by disturbances from both natural processes and human activities 1, [26][27][28][29][30][31][32][33] , such as wildfires 17,[34][35][36] . For example, in parts of the Amazon rainforest, wood density in secondary forests was found to be 33% lower compared to pre-disturbance conditions 37,38 .…”

The density of wood is a key indicator of trees’ carbon investment strategies, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls remain poorly understood, preventing accurate predictions of global forest carbon stocks. Here, we analyze information from 1.1 million forest inventory plots alongside wood density data from 10,703 tree species to create a spatially-explicit understanding of the global wood density distribution and its drivers. Our findings reveal a pronounced latitudinal gradient, with wood in tropical dry forests being up to twice as dense as that in boreal forests. In both angiosperms and gymnosperms, temperature and water availability emerged as the primary factors influencing the variation in wood density globally. This indicates similar environmental filters and evolutionary adaptations among distinct plant groups, underscoring the essential role of abiotic factors in determining wood density in forest ecosystems. Additionally, our study highlights the prominent role of disturbance, such as human modification and fire risk, in influencing wood density at more local scales. Factoring in the spatial variation of wood density notably changes the estimates of forest carbon stocks, leading to differences of up to 21% within biomes. Therefore, our research contributes to a deeper understanding of terrestrial biomass distribution and how environmental changes and disturbances impact forest ecosystems.

The density of wood is a key indicator of the carbon investment strategies of trees, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls remain poorly understood, preventing accurate predictions of global forest carbon stocks. Here we analyse information from 1.1 million forest inventory plots alongside wood density data from 10,703 tree species to create a spatially explicit understanding of the global wood density distribution and its drivers. Our findings reveal a pronounced latitudinal gradient, with wood in tropical forests being up to 30% denser than that in boreal forests. In both angiosperms and gymnosperms, hydrothermal conditions represented by annual mean temperature and soil moisture emerged as the primary factors influencing the variation in wood density globally. This indicates similar environmental filters and evolutionary adaptations among distinct plant groups, underscoring the essential role of abiotic factors in determining wood density in forest ecosystems. Additionally, our study highlights the prominent role of disturbance, such as human modification and fire risk, in influencing wood density at more local scales. Factoring in the spatial variation of wood density notably changes the estimates of forest carbon stocks, leading to differences of up to 21% within biomes.
