  • This study reveals how understory forest plants in the Central Amazon adapt their nutrient acquisition strategies in response to elevated atmospheric CO₂, based on an in situ open-top chamber experiment. To support the CO₂ fertilization effect, plants adjust contrasting strategies to extract nutrients from litter and soil layers. This process intensifies competition between plants and microbes and may lead to declines in soil organic phosphorus, with important implications for carbon–phosphorus dynamics and the resilience of forests under climate change.

  • Wood density is a key control on tree biomass, and understanding its spatial variation improves estimates of forest carbon stock. Sullivan et al. measure >900 forest plots to quantify wood density and produce high resolution maps of its variation across South American tropical forests.

  • Most Amazon tree species are rare but a small proportion are common across the region. The authors show that different species are hyperdominant in different size classes and that hyperdominance is more phylogenetically restricted for larger canopy trees than for smaller understory ones.
