The response of small understory trees to long-term drought is vital in determining the future composition, carbon stocks and dynamics tropical forests. Long-term is, however, also likely expose increased light availability driven by drought-induced mortality. Relatively little known about potential for adjust their physiology both decreasing water increasing availability. We analysed data on maximum photosynthetic capacity (Jmax , Vcmax ), leaf respiration (Rleaf mass per area (LMA),...
Abstract Whether tropical trees acclimate to long‐term drought stress remains unclear. This uncertainty is amplified if accompanied by changes in other drivers such as the increases canopy light exposure that might be induced tree mortality or disturbances. Photosynthetic capacity, leaf respiration, non‐structural carbohydrate (NSC) storage and stomatal conductance were measured on 162 at world's longest running (15 years) forest experiment. We test whether surviving have altered strategies...
Societal Impact Statement Understanding of tropical forests has been revolutionized by monitoring in permanent plots. Data from global plot networks have transformed our knowledge forests’ diversity, function, contribution to biogeochemical cycles, and sensitivity climate change. Monitoring thus far concentrated rain forests. Despite increasing appreciation their threatened status, biodiversity, importance the carbon cycle, dry is still its infancy. We provide a protocol for plots Expanding...
Future climate change predictions for tropical forests highlight increased frequency and intensity of extreme drought events. However, it remains unclear whether large small trees have differential strategies to tolerate due the different niches they occupy. The future is ultimately dependent on capacity (<10 cm in diameter) adjust their hydraulic system drought. To address this question, we evaluated tolerance neotropical can experimental water stress was from tall trees. We measured...
Abstract Motivation Leaf traits represent an important component of plant functional strategies, and those related to carbon fixation nutrient acquisition form the leaf economics spectrum. However, observations are underrepresented in tropical regions comparison with temperate areas. Brazil, a country continental scale vast biodiversity is timely example, where many biomes impacted by human activities climate change. relevant understand vegetation responses these impacts remain poorly...
The Brazilian cerrado occupies land that could be occupied by seasonal forest, given current climatic conditions and their spatial proximity. Soil has been identified as one of the main determinants forest prevalence. We tested whether woody floras were assembled different processes. postulated soil nutrient availability would account for differences in functional phylogenetic structure forest. In 100 5 × m plots distributed along patches south-eastern Brazil, we sampled five individuals...
From heightened canopy dieback to tree die-off, many forest ecosystems are showing signs of poorly coping with more severe, frequent, or hotter droughts. Understanding resilience drought has become paramount, and eco&#8208;physiological optimisation approaches that test behavioural hypotheses have been proposed as a means build this understanding in global terrestrial models. Here, we used land-surface model considers competing optimality principles simulate gas exchange leaf nitrogen...
The future of tropical forests is dependent on the capacity young trees to adjust drought. We evaluated multiple hydraulic traits indicative drought tolerance small across nine common genera at world’s longest-running throughfall exclusion experiment and compared their responses with surviving large canopy trees. Small understorey increased specific conductivity by 56.3% leaf:sapwood area ratio 45.6% in response treatment. However, both a control treatment had significantly lower minimum...

&lt;p&gt;Leaf construction can be costly to plants with a short leaf lifespan (LLS), necessity pay back the investment in deployment. Costs of are often measured as mass per area (LMA) and deciduousness strategies (deciduous, semideciduous or evergreen) used proxy LLS (evergreen species having longest duration compared deciduous species). According economic spectrum theory, positive correlation between LMA is expected, evergreen higher than species. Nonetheless, aridity constraints...
