Long-term decline in above-ground carbon sinks in Brazilian tropical and subtropical forests

Vinícius Andrade Maia, Natália de Aguiar‐Campos, Fernanda Coelho de Souza, Cléber Rodrigo de Souza et autres

Recent evidence indicates that Brazilian forests are shifting from persistent carbon sinks to emerging carbon sources, with important implications for the global climate. To investigate this trend, we analyse long-term census data from 49 forest sites spanning southeast and southern Brazil, including …

Family imprint reveals basin-wide patterns of Amazon forest embolism resistance

Julia Valentim Tavares, E. Gloor, Thiago S. F. Silva, Rafael S. Oliveira et autres

Abstract Amazon rainforests face intensifying water stress due to increases in vapour pressure deficit and changing hydrological regimes. Embolism resistance (Ψ 50 ) is a critical metric of tree survival under drought conditions, it is defined as a plant’s capacity to resist …

Centuries of compounding human influence on Amazonian forests

Crystal N. H. McMichael, Mark B. Bush, Hans ter Steege, Dolores R. Piperno et autres

Recent evidence suggests that the ecological footprints of pre-Columbian Indigenous peoples in Amazonia persist in modern forests. Ecological impacts resulting from European colonization c. 1550 CE and the Amazonian Rubber Boom c. 1850 to 1920 CE are largely unexplored but could be …

Variation in wood density across South American tropical forests

Martin J. P. Sullivan, Oliver L. Phillips, David Galbraith, Everton Cristo de Almeida et autres

Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates and carbon maps. The need to understand how and why wood density varies is especially …

Tropical forests in the Americas are changing too slowly to track climate change

Jesús Aguirre‐Gutiérrez, Sandra Dı́az, Sami W. Rifai, José Javier Corral‐Rivas et autres

Understanding the capacity of forests to adapt to climate change is of pivotal importance for conservation science, yet this is still widely unknown. This knowledge gap is particularly acute in high-biodiversity tropical forests. Here, we examined how tropical forests of the Americas …

Functional composition of the Amazonian tree flora and forests

Hans ter Steege, Lourens Poorter, Jesús Aguirre‐Gutiérrez, Claire Fortunel et autres

Plants cope with the environment by displaying large phenotypic variation. Two spectra of global plant form and function have been identified: a size spectrum from small to tall species with increasing stem tissue density, leaf size, and seed mass; a leaf economics …

Phylogenetic conservatism in the relationship between functional and demographic characteristics in Amazon tree taxa

Pablo Sanchez‐Martinez, Kyle G. Dexter, Frederick C. Draper, Christopher Baraloto et autres

Abstract Leaf and wood functional traits of trees are related to growth, reproduction, and survival, but the degree of phylogenetic conservatism in these relationships is largely unknown. In this study, we describe the variability of strategies involving leaf, wood and demographic characteristics …

The biogeography of the Amazonian tree flora

Bruno Garcia Luize, Hanna Tuomisto, Robin Ekelschot, Kyle G. Dexter et autres

We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 …

Biomass Equations and Carbon Stock Estimates for the Southeastern Brazilian Atlantic Forest

Tatiana Dias Gaui, Vinícius Costa Cysneiros, Fernanda Coelho de Souza, Hallefy Júnio de Souza et autres

Tropical forests play an important role in mitigating global climate change, emphasizing the need for reliable estimates of forest carbon stocks at regional and global scales. This is essential for effective carbon management, which involves strategies like emission reduction and enhanced carbon …
