Biodiversity loss is one of the main challenges our time,1,2 and attempts to address it require a clear understanding how ecological communities respond environmental change across time space.3,4 While increasing availability global databases on has advanced knowledge biodiversity sensitivity changes,5,6,7 vast areas tropics remain understudied.8,9,10,11 In American tropics, Amazonia stands out as world's most diverse rainforest primary source Neotropical biodiversity,12 but remains among...
Summary Human alteration of the global environment is leading to a pervasive loss biodiversity. Most studies evaluating human impacts on biodiversity occur after disturbance has taken place using spatially distinct sites determine undisturbed reference condition. This approach known as space‐for‐time ( SFT ) substitution. However, substitution could be underestimating if spatial controls fail provide adequate inferences about pre‐disturbance conditions. We compare with before–after...
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...
Abstract Building trust in science and evidence-based decision-making depends heavily on the credibility of studies their findings. Researchers employ many different study designs that vary risk bias to evaluate true effect interventions or impacts. Here, we empirically quantify, a large scale, prevalence magnitude estimates. Randomised controlled observational with pre-intervention sampling were used by just 23% intervention biodiversity conservation, 36% social science. We demonstrate,...
Exotic plants reduce carbon sequestration Invasive exotic have become a major problem worldwide, with transformational effects on the composition and function of ecosystems. In multifactorial experiment in New Zealand, Waller et al. show that accelerate loss from soils through their interactions invertebrate herbivores soil biota (see Perspective by Urcelay Austin). They built 160 mini-ecosystems field, manipulating among plants, herbivores, biota. Key biological abiotic responses were...
Significance Amazonia is experiencing an increase in the frequency of extreme droughts and wildfires. However, duration their impacts on plant mortality carbon stocks are poorly known, it unclear whether amplified forests with a history previous human disturbance. We show that rates remain above baseline levels for over 3 y affected by drought 2.5 both fire. A disturbance led to greater simultaneously Our assessment area covering 1.2% Brazilian Amazon shows regional fires can have globally...
Human activities pose a major threat to tropical forest biodiversity and ecosystem services. Although the impacts of deforestation are well studied, multiple land-use land-cover transitions (LULCTs) occur in landscapes, we do not know how LULCTs differ their rates or on key components. Here, quantified 18 three components (biodiversity, carbon, soil), based variables collected from 310 sites Brazilian Amazon. Across all LULCTs, was most affected component, followed by carbon stocks, but...
The convergence of the biodiversity and climate crises, widening wealth inequality, most recently COVID-19 pandemic underscore urgent need to mobilize change secure sustainable futures. Centres tropical are a major focus conservation efforts, delivered in predominantly site-level interventions often incorporating alternative-livelihood provision or poverty-alleviation components. Yet, on intervention is ill-equipped address disproportionate role (often distant) collapse. Further these...
Interactions between plants and herbivores are central in most ecosystems, but their strength is highly variable. The amount of variability within a system thought to influence aspects plant-herbivore biology, from ecological stability plant defense evolution. Our understanding what influences variability, however, limited by sparse data. We collected standardized surveys herbivory for 503 species at 790 sites across 116° latitude. With these data, we show that within-population increases...
The Brazilian Amazon is one of Earth's most biodiverse and ecologically important regions. However, research investments for biodiversity in the biome are disproportionately low compared with other regions Brazil. In 2022, received 13% master's, doctoral postdoctoral scholarships hosted 11% all researchers working postgraduate programs. Amazonian institutions approximately 10% federal budget spent on grants about 23% resources destined to support long-term ecological sites. cities Manaus...
Wildfires produce substantial CO2 emissions in the humid tropics during El Niño-mediated extreme droughts, and these are expected to increase coming decades. Immediate carbon from uncontrolled wildfires human-modified tropical forests can be considerable owing high necromass fuel loads. Yet, data on combustion severely lacking. Here, we evaluated stocks before after 2015-2016 Niño Amazonian distributed along a gradient of prior human disturbance. We then used Landsat-derived burn scars...
Biodiversity–ecosystem functioning (BEF) literature is dominated by investigations conducted in temperate grassland ecosystems under homogenous environmental conditions. Consequently, studies concerned with the functional importance of higher trophic levels, or role conditions shaping BEF relationships, are comparatively uncommon. To address this, we assessed dung beetle diversity‐functioning relationships situ, a field experiment Brazilian Amazon. Dung beetles perform number ecological...
Hundreds of millions hectares tropical forest have been selectively logged, either legally or illegally. Methods for detecting and monitoring selective logging using satellite data are at an early stage, with current methods only able to detect more intensive timber harvest (>20 m3 ha−1). The spatial resolution widely available datasets, like Landsat, previously considered too coarse measure the subtle changes in forests associated less logging, yet most present-day is low intensity. We...
Abstract Wildfires in humid tropical forests have become more common recent years, increasing the rates of tree mortality that not co-evolved with fire. Estimating carbon emissions from these wildfires is complex. Current approaches rely on estimates committed based static emission factors through time and space, yet cannot be assigned to specific thus are comparable other temporally-explicit sources. Moreover, gross estimates, whereas long-term consequences require an understanding net...
Human-modified forests are an ever-increasing feature across the Amazon Basin, but little is known about how stem growth influenced by extreme climatic events and resulting wildfires. Here we assess for first time impacts of human-driven disturbance in combination with El Niño–mediated droughts fires on tree carbon accumulation. We found that after 2.5 years continuous measurements, there was no difference accumulation between undisturbed human-modified forests. Furthermore, drought caused...
Summary Understanding how selective logging affects biodiversity is crucial to planning cost-effective conservation strategies in tropical forests, yet there limited understanding of its impacts on fauna functional diversity the Americas. We assessed intensification and time since influence multiple metrics integrity Brazilian Amazon by collecting bird dung beetle data within 48 management units that had experienced varying exploitation intensities between 1.5–2.0 5.0–6.0 years before faunal...
Abstract The increased global demand for tropical timber has driven vast expanses of forests to be selectively logged worldwide. While logging impacts on wildlife are predicted change species distribution and abundance, the underlying physiological responses poorly understood. Although there is a growing consensus that selective natural populations start with individual stress‐induced sublethal responses, this literature dominated by investigations conducted vertebrates from temperate zones....
Abstract Our knowledge of how tropical forest biodiversity and functioning respond to anthropogenic climate‐associated stressors is limited. Research exploring El Niño impacts are scarce or based on single post‐disturbance assessments, few studies assess forests previously affected by disturbance. Focusing dung beetles associated ecological functions, we assessed (a) the effects a strong Niño, (b) if post‐El beetle responses were influenced previous disturbance, (c) these compare between...
