Abstract Tropical forests are complex systems containing myriad interactions and feedbacks with their biotic abiotic environments, but as the world changes fast, future of these ecosystems becomes increasingly uncertain. In particular, global stressors may unbalance that stabilize tropical forests, allowing other to propel undesired in whole ecosystem. Here, we review scientific literature across various fields, compiling known environment, including climate, rainfall, aerosols, fire, soils, fauna, human activities. We identify 170 individual among 32 elements present a forest network, countless feedback loops emerge from different combinations interactions. illustrate our findings three cases involving urgent sustainability issues: (1) wildfires wetlands South America; (2) encroachment African savanna landscapes; (3) synergistic threats peatland Borneo.

Abstract Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, influence ecosystem properties their benefits detriments people. trait data thus represent the basis for a vast area research spanning from evolutionary biology, community functional ecology, biodiversity conservation, landscape management, restoration, biogeography earth system modelling. Since its foundation in 2007, TRY database plant traits has grown continuously. It now provides unprecedented coverage under an open access policy is main used by worldwide. Increasingly, also supports new frontiers trait‐based research, including identification gaps subsequent mobilization or measurement data. To support this development, article we evaluate extent compiled analyse emerging patterns representativeness. Best species achieved categorical traits—almost complete ‘plant growth form’. However, most relevant ecology vegetation modelling are characterized continuous intraspecific variation trait–environmental relationships. These have be measured on individual respective environment. Despite coverage, observe humbling lack completeness representativeness these many aspects. We, therefore, conclude that reducing biases remains key challenge requires coordinated approach measurements. This can only collaboration with initiatives.

Trees are the living foundations on which most terrestrial biodiversity is built. Central to success of trees their woody bodies, connect elevated photosynthetic canopies with essential belowground activities water and nutrient acquisition. The slow construction these carbon-dense, skeletons leads a generation time, leaving forests highly susceptible rapid changes in climate. Other long-lived, sessile organisms such as corals appear be poorly equipped survive changes, raises questions about vulnerability contemporary future climate change. emerging view that, similar corals, tree species have rather inflexible damage thresholds, particularly terms stress, especially concerning.

Recent observations of elevated tree mortality following climate extremes, like heat and drought, raise concerns about change risks to global forest health. We currently lack both sufficient data understanding identify whether these represent a trend toward increasing mortality. Here, we document events sudden unexpected drought in ecosystems that previously were considered tolerant or not at risk exposure.

Abstract Drought‐related tree mortality is now a widespread phenomenon predicted to increase in magnitude with climate change.

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 plots across America show biomass ceased during event balance becoming indistinguishable from zero (−0.02 ± 0.37 Mg C ha −1 per year). However, intact overall were no sensitive Niño than previous less intense events, remaining a key defence against climate change as long protected.

The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers death remain largely unknown. Here we present a pan-Amazonian assessment how and why trees die, analysing over 120,000 representing > 3800 species from 189 long-term RAINFOR forest plots. While mortality rates vary greatly Amazon-wide, on average are as likely to die standing they broken or uprooted-modes with different ecological consequences. Species-level growth rate single most important predictor in Amazonia, faster-growing being at higher risk. Within species, however, slowest-growing greatest risk while effect size varies across basin. In driest Amazonian region species-level bioclimatic distributional patterns also predict death, suggesting that these experiencing climatic conditions beyond their adaptative limits. These results provide not only holistic picture but large-scale evidence for overarching importance growth-survival trade-off driving
