Carbon storage is widely acknowledged as one of the most valuable forest ecosystem services. Deforestation, logging, fragmentation, fire, and climate change have significant effects on tropical carbon stocks; however, an elusive yet undetected decrease in may be due to defaunation large seed dispersers. Many trees with sizeable contributions stock rely vertebrates for dispersal regeneration, however many these frugivores are threatened by hunting, illegal trade, habitat loss. We used a data...
ABSTRACT Motivation The accelerated and widespread conversion of once continuous ecosystems into fragmented landscapes has driven ecological research to understand the response biodiversity local (fragment size) landscape (forest cover fragmentation) changes. This information important theoretical applied implications, but is still far from complete. We compiled most comprehensive updated database investigate how these changes determine species composition, abundance trait diversity multiple...
Summary Fragmentation of tropical forests is one the greatest threats to global biodiversity. Understanding how biological and functional attributes communities respond fragmentation and, in turn, whether ecosystem functioning impacted upon are critical steps for assessing long‐term effects conservation values forest fragments. Ecosystem can be inferred through diversity metrics, including richness, evenness divergence, which collectively quantify range, distribution uniqueness traits within...
Tropical forests store large amounts of carbon and high biodiversity, but are being degraded at alarming rates. The emerging global Forest Landscape Restoration (FLR) agenda seeks to limit climate change by removing dioxide from the atmosphere through growth trees. In doing so, it may also protect biodiversity as a free cobenefit, which is vital given massive shortfall in funding for conservation. We investigated whether natural forest regeneration on abandoned pastureland offers such...
Understanding the mechanisms controlling forest carbon storage is crucial to support “nature-based” solutions for climate change mitigation. We used a dataset of 892 Atlantic Forest inventories assess direct and indirect effects environmental conditions, human impacts, tree community proprieties, sampling methods on above-ground stocks. showed that widely accepted drivers stocks, such as climate, soil, topography, fragmentation, have much smaller role than disturbance history functional...
Abstract Based on sampling data, we propose a rigorous standardization method to measure and compare beta diversity across datasets. Here diversity, which quantifies the extent of among‐assemblage differentiation, relies Whittaker's original multiplicative decomposition scheme, but use Hill numbers for any order q ≥ 0. Richness‐based ( = 0) species identity shift, whereas abundance‐based > also difference among assemblages in abundance. We adopt define assumptions statistical model as...
Tropical forests store vast amounts of carbon and are the most biodiverse terrestrial habitats, yet they being converted degraded at alarming rates. Given global shortfalls in budgets required to prevent biodiversity loss, we need seek solutions that simultaneously address both issues. Of particular interest carbon-based payments under Reducing Emissions from Deforestation Forest Degradation (REDD+) mechanism also conserve no additional cost. One potential is for REDD+ protect forest...
Summary Fragmentation of tropical forests is a major driver the global extinction crisis. A key question understanding how fragmentation impacts phylogenetic diversity, which summarizes total evolutionary history shared across species within community. Conserving diversity decreases potential losing unique ecological and phenotypic traits plays important roles in maintaining ecosystem function stability. Our study was conducted landscapes highly fragmented Brazilian Atlantic forest. We...
Summary Tropical forests are critical for protecting global biodiversity and carbon stores. While forest degradation fragmentation cause negative impacts on trees, many woody lianas benefit, with associated effects storage. Here, we focus the key question of how abiotic environmental changes resulting from tropical mediate allocation into trees lianas. We globally threatened Brazilian Atlantic Forest, in fragments spanning 13–23 442 ha area at fragment edges interiors. Within each fragment,...
Climate and soil are among the most important factors determining variation in tree communities, but their effects have not been thoroughly elucidated to date for many vegetation features. In this study, we evaluate how climate gradients affect of composition, species diversity dominance, structure functional traits (seed mass wood density) using over 327 000 trees 158 sites distributed along environmental transitions Atlantic forest, Cerrado Caatinga Minas Gerais State (MG), Brazil (nearly...
Abstract Fragmented tropical forest landscapes preserve much of the remaining biodiversity and carbon stocks. Climate change is expected to intensify droughts increase fire hazard intensities, thereby causing habitat deterioration, losses stock losses. Understanding trajectories that these may follow under increased climate pressure imperative for establishing strategies conservation ecosystem services. Here, we used a quantitative predictive modelling approach project spatial distribution...
Under the UN-Decade of Ecosystem Restoration and Bonn Challenge, second-growth forest is promoted as a global solution to climate change, degradation associated losses biodiversity ecosystem services. Second growth often invaded by alien tree species understanding how this impacts carbon stock recovery key for restoration planning. We assessed diversity in second two Acacia non-invaded growth, with edge effects, Brazilian Atlantic Forest. Carbon forests was threefold lower than forests....

Abstract Quantifying the impact of habitat disturbance on ecosystem function is critical to understanding and predicting future tropical forests. Many studies have examined post‐disturbance changes in animal traits related mutualistic interactions with plants, but effect plant diverse forests has received much less attention. Focusing two study regions eastern Brazilian Amazon, we used a trait‐based approach examine how seed dispersal functionality within communities across landscape‐scale...
The aim of this study was to determine changes in composition, abundance and richness species along a forest gradient with varying soils flood regimes. forests are located on the left bank lower Jucu River, Jacarenema Natural Municipal Park, Espírito Santo. A survey shrub/tree done 80 plots, 5x25 m, equally distributed among studied. We included sampling all individuals >3.2 cm diameter at breast height (1.30 m). Soil samples were collected from surface layer (0-10 cm) each plot for chemical...
A presente pesquisa teve como objetivo analisar as variações fitofisionômicas em quatro formações florestais, relação aos gradientes de inundação e características pedológicas. O estudo foi no Parque Natural Municipal Jacarenema, Vila Velha, Espírito Santo. Quatro perfis solo com profundidades variadas foram abertos, onde uma amostra coletada cada horizonte existente por perfil. Para acompanhamento da flutuação do lençol freático, instalados piezômetros, profundidade 2 m fitofisionomia....
Estimating the species, phylogenetic, and functional diversity of a community is challenging because rare species are often undetected, even with intensive sampling. The Good-Turing frequency formula, originally developed for cryptography, estimates in an ecological context true frequencies single assemblage based on incomplete sample individuals. Until now, this formula has never been used to estimate undetected diversity. Here, we first generalize sampling two assemblages. original its...
