abstract = "While the climate and human-induced forest degradation is
increasing in the Amazon, fire impacts on forest dynamics remain
understudied in the wetter regions of the basin, which are
susceptible to large wildfires only during extreme droughts. To
address this gap, we installed burned and unburned plots
immediately after a wildfire in the northern Purus-Madeira
(Central Amazon) during the 2015 El-Niņo. We measured all
individuals with diameter of 10 cm or more at breast height and
conducted recensuses to track the demographic drivers of biomass
change over 3 years. We also assessed how stem-level growth and
mortality were influenced by fire intensity (proxied by char
height) and tree morphological traits (size and wood density).
Overall, the burned forest lost 27.3% of stem density and 12.8% of
biomass, concentrated in small and medium trees. Mortality drove
these losses in the first 2 years and recruitment decreased in the
third year. The fire increased growth in lower wood density and
larger sized trees, while char height had transitory strong
effects increasing tree mortality. Our findings suggest that fire
impacts are weaker in the wetter Amazon. Here, trees of greater
sizes and higher wood densities may confer a margin of fire
resistance; however, this may not extend to higher intensity fires
arising from climate change.",
