Fire effects on different successional groups of tree species in the southwestern Brazilian Amazon

Izaias Bernardo Monteiro da Silva, Patrícia Nakayama Miranda, Liana O. Anderson, Camila V. J. Silva et autres

Aim of study: Human-driven wildfires are frequent events in the Amazon rainforest and can lead to changes in the composition and structure of plant communities. To contribute to this discussion, this work aims to evaluate the fire effect after 10 years on …

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 …

Fire effect on bamboo-dominated forests in Southwestern Amazon: impacts on tree diversity and forest structure

Izaias Brasil da Silva, Patrícia Nakayama Miranda, Liana O. Anderson, Camila V. J. Silva et autres

Severe droughts increase the forest flammability, especially if fires are recurrent. Considering that fires tend to alter the forest structure and reduce biological diversity, we analyzed the fire effect on the tree plant community and forest structure over a 10-year post-fire period. …

Pervasive gaps in Amazonian ecological research

Raquel L. Carvalho, Angélica Faria de Resende, Jos Barlow, Filipe França et autres

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities …

Ancient fires enhance Amazon forest drought resistance

Laura B. Vedovato, Lidiany Camila da Silva Carvalho, Luiz E. O. C. Aragão, Michael I. Bird et autres

Drought and fire reduce productivity and increase tree mortality in tropical forests. Fires also produce pyrogenic carbon (PyC), which persists in situ for centuries to millennia, and represents a legacy of past fires, potentially improving soil fertility and water holding capacity and …

The drivers and impacts of Amazon forest degradation

David M. Lapola, Patrícia Pinho, Jos Barlow, Luiz E. O. C. Aragão et autres

Approximately 2.5 × 10 6 square kilometers of the Amazon forest are currently degraded by fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all remaining forests in the region. Carbon emissions from this degradation total up to 0.2 petagrams …

Exploring the Role of Deforestation and Cropland Expansion in Driving a Fire-Transition in the Brazilian Amazon

Paulo Amador Tavares, Joice Ferreira, Camila V. J. Silva, Érika Berenguer et autres

The Brazilian Amazonian Forest is undergoing significant changes in land use and land cover in the last few decades. This land-use transition, besides climate change, may be responsible for the fire regime transition in this territory. Therefore, we aimed at investigating how …

Water table depth modulates productivity and biomass across Amazonian forests

Thaiane R. Sousa, Juliana Schietti, Igor Oliveira Ribeiro, Thaíse Emilio et autres

Abstract Aim Water availability is the major driver of tropical forest structure and dynamics. Most research has focused on the impacts of climatic water availability, whereas remarkably little is known about the influence of water table depth and excess soil water on …

Quantifying Post-Fire Changes in the Aboveground Biomass of an Amazonian Forest Based on Field and Remote Sensing Data

Aline Pontes Lopes, Ricardo Dalagnol, Andeise Cerqueira Dutra, Camila V. J. Silva et autres

Fire is a major forest degradation component in the Amazon forests. Therefore, it is important to improve our understanding of how the post-fire canopy structure changes cascade through the spectral signals registered by medium-resolution satellite sensors over time. We contrasted accumulated yearly …
