Abstract Aim Tropical forests store 25% of global carbon and harbour 96% the world's tree species, but it is not clear whether this high biodiversity matters for storage. Few studies have teased apart relative importance forest attributes environmental drivers ecosystem functioning, no such study exists tropics. Location Neotropics. Methods We relate aboveground biomass ( AGB ) to (diversity structure) (annual rainfall soil fertility) using data from 144,000 trees, 2050 plots 59 sites. The...
Thermal sensitivity of tropical trees A key uncertainty in climate change models is the thermal forests and how this value might influence carbon fluxes. Sullivan et al. measured stocks fluxes permanent forest plots distributed globally. This synthesis plot networks across climatic biogeographic gradients shows that dominated by high daytime temperatures. extreme condition depresses growth rates shortens time resides ecosystem killing under hot, dry conditions. The effect temperature worse...
Estimates of extinction risk for Amazonian plant and animal species are rare not often incorporated into land-use policy conservation planning. We overlay spatial distribution models with historical projected deforestation to show that at least 36% up 57% all tree likely qualify as globally threatened under International Union Conservation Nature (IUCN) Red List criteria. If confirmed, these results would increase the number on Earth by 22%. trends observed in Amazonia apply trees throughout...
Abstract Tropical forests face increasing climate risk 1,2 , yet our ability to predict their response change is limited by poor understanding of resistance water stress. Although xylem embolism thresholds (for example, $$\varPsi $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>Ψ</mml:mi> </mml:math> 50 ) and hydraulic safety margins HSM are important predictors drought-induced mortality 3–5 little known about how these vary across Earth’s largest tropical forest. Here,...
Abstract The tropical forest carbon sink is known to be drought sensitive, but it unclear which forests are the most vulnerable extreme events. Forests with hotter and drier baseline conditions may protected by prior adaptation, or more because they operate closer physiological limits. Here we report that in South American climates experienced greatest impacts of 2015–2016 El Niño, indicating greater vulnerability temperatures drought. long-term, ground-measured tree-by-tree responses 123...
Understanding the capacity of forests to adapt climate change is pivotal importance for conservation science, yet this still widely unknown. This knowledge gap particularly acute in high-biodiversity tropical forests. Here, we examined how Americas have shifted community trait composition recent decades as a response changes climate. Based on historical trait-climate relationships, found that, overall, studied functional traits show shifts less than 8% what would be expected given observed...
Abstract Species distribution models (SDMs) are widely used in ecology and conservation. Presence-only SDMs such as MaxEnt frequently use natural history collections (NHCs) occurrence data, given their huge numbers accessibility. NHCs often spatially biased which may generate inaccuracies SDMs. Here, we test how the of predictions relates to a spatial abundance model, based on large plot dataset for Amazonian tree species, using inverse distance weighting (IDW). We also propose new pipeline...
Drought-induced wildfires have increased in frequency and extent over the tropics. Yet, long-term (greater than 10 years) responses of Amazonian lowland forests to fire disturbance are poorly known. To understand post-fire forest biomass dynamics, assess time required for fire-affected recover pre-disturbance levels, we combined 16 single with 182 multiple census into a unique large-scale dataset across Brazilian Amazonia. We quantified biomass, mortality wood productivity burned plots along...
The historical course of evolutionary diversification shapes the current distribution biodiversity, but main forces constraining are still a subject debate. We unveil structure tree species assemblages across Americas to assess whether an inability move or evolve is predominant constraint in plant and biogeography. find fundamental divide lineage composition between tropical extratropical environments, defined by absence versus presence freezing temperatures. Within Neotropics, we uncover...
Abstract Global patterns of species and evolutionary diversity in plants are primarily determined by a temperature gradient, but precipitation gradients may be more important within the tropics, where plant richness is positively associated with amount rainfall. The impact on distribution diversity, however, largely unexplored. Here we detail how varies along bringing together comprehensive database composition angiosperm tree communities across lowland tropical South America (2,025...
Lineages tend to retain ecological characteristics of their ancestors through time. However, for some traits, selection during evolutionary history may have also played a role in determining trait values. To address the relative importance these processes requires large-scale quantification traits and relationships among species. The Amazonian tree flora comprises high diversity angiosperm lineages species with widely differing life-history characteristics, providing an excellent system...
Abstract The intensity and frequency of severe droughts in the Amazon region have increased recent decades. These extreme events are associated with changes forest dynamics, biomass floristic composition. However, most studies drought response focused on upland forests deep water tables, which may be especially sensitive to drought. Palms, tend dominate less well‐drained soils, also been neglected. relative neglect shallow tables palms is a significant concern for our understanding tropical...
Abstract 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 carbon maps. The need understand how why wood varies especially tropical America where forests have exceptional species diversity turnover composition. As identity composition are challenging estimate remotely, ground surveys essential know the trees, whether measured directly or inferred from their identity. Here, we...
Abstract Aim To investigate the geographic patterns and ecological correlates in distribution of most common tree dispersal modes Amazonia (endozoochory, synzoochory, anemochory hydrochory). We examined if proportional abundance these could be explained by availability agents (disperser‐availability hypothesis) and/or resources for constructing zoochorous fruits (resource‐availability hypothesis). Time period Tree‐inventory plots established between 1934 2019. Major taxa studied Trees with a...
Abstract Large‐scale data compilation is increasing steadily in tropical forest research, but the lack of standardized methods for collection limits drawing inference from large datasets and cross‐biome analyses. Different inclusion minimum tree diameter threshold are among these varying factors. To tackle this issue, we evaluated how different approaches sampling affects our understanding diversity functioning vegetation types. We used a unique dataset 44 inventory plots (43.54 ha)...
Tree allometric models are generally developed at local scales and thus potentially biased when used for different locations broader spatial scales. Because relationships vary with forest structure, climatic conditions edaphic properties, one potential way to address this issue consistently estimate tree allometry, may involve including new explanatory variables into models. Here, using an extensive dataset of 566 trees widely distributed over Rio de Janeiro state, Brazil, we investigated...
Abstract The extent (or lack) of phylogenetic signal for key ecological traits reveals the role evolutionary processes on present‐day ecosystem function and hints future trends under climate change scenarios. This approach has been applied to South American tropical moist forests, but not highly threatened seasonally dry forests (SDTF), despite acknowledgement their unique history. To fill this knowledge gap, we investigated legacy vital characteristics among SDTF trees: regional dominance,...
Tropical forests play an important role in mitigating global climate change, emphasizing the need for reliable estimates of forest carbon stocks at regional and scales. This is essential effective management, which involves strategies like emission reduction enhanced sequestration through restoration conservation. However, sample-based estimations require accurate allometric equations, are lacking rainforests Atlantic Forest Domain (AFD). In this study, we fitted biomass equations three main...
Abstract The historical course of evolutionary diversification shapes the current distribution biodiversity, but main forces constraining are unclear. We unveil structure tree species diversity across Americas to assess whether an inability move (dispersal limitation) or evolve (niche conservatism) is predominant constraint in plant and biogeography. find a fundamental divide lineage composition between tropical extratropical environments, defined by absence versus presence freezing...
