Article
Accidental fires pose a huge threat to the integrity of tropical forests, including the social forests managed by traditional populations in the Brazilian Amazon. Thus, understanding and incorporating the perception of local actors in strategies to search for solutions is an urgent demand. This study examines the perception of residents of three in...

The Caatinga dry forest in northeastern Brazil represents one of the most species‐rich dry forests globally. It is densely populated, contains economically undeveloped areas, and harbors increasingly degraded irreplaceable biota. In response to human disturbance, forests have been replaced by shrubs, and desertification is expanding. Seedling recru...
Article
Climate change is one of the main drivers of biological reorganization, population decline of pollinators, and disruption of species interactions. These impacts represent a major threat to crop pollination and human food security. Here, we tested the hypothesis that the spatial mismatches between Neotropical food plant species and their bee pollina...
Article
Full-text available
Habitat fragmentation generally reduces biodiversity at the patch scale (α diversity)¹. However, there is ongoing debate about whether such negative effects can be alleviated at the landscape scale (γ diversity) if among-patch diversity (β diversity) increases as a result of fragmentation2, 3, 4, 5–6. This controversial view has not been rigorously...
Article
Full-text available
Motivation The accelerated and widespread conversion of once continuous ecosystems into fragmented landscapes has driven ecological research to understand the response of biodiversity to local (fragment size) and landscape (forest cover and fragmentation) changes. This information has important theoretical and applied implications, but is still far...
Article
Tropical dry forests are currently exposed to slash-and-burn agriculture, livestock production, exploitation of forest products and increasing aridity, with impacts on primary productivity still to be investigated. In this study, we investigated how chronic anthropogenic disturbance and reduced rainfall affect the woody biomass of Pityrocarpa monil...
Article
Full-text available
Human activities have converted mature forests into mosaics of successional vegetation and chronically disturbed habitats, altering the patterns of population distribution, foraging ecology and thus, the flow of matter and nutrients through ecosystems. Although the effects of human disturbance are mostly harmful, hyperabundant native generalist spe...
Article
Full-text available
Anthropogenic landscape modification may lead to the proliferation of a few species and the loss of many. Here we investigate mechanisms and functional consequences of this winner–loser replacement in six human-modified Amazonian and Atlantic Forest regions in Brazil using a causal inference framework. Combining floristic and functional trait data...
Article
Full-text available
Habitat loss can lead to biotic homogenization (decrease in β diversity) or differentiation (increase in β diversity) of biological communities. However, it is unclear which of these ecological processes predominates in human-modified landscapes. We used data on vertebrates, invertebrates, and plants to quantify β diversity based on species occurre...

Full-text available
Wildfires associated with land-use and climate change have considered a key driver to the Amazon forest collapse. However, achieving a detailed understanding of how human-related disturbances impact forest successional trajectories needs comprehensive information spanning forest strata. Here, we investigate the impact of recurrent wildfires on fore...
Article
Full-text available
Here, we examine the effects of wildfires on the soil seed bank of a terra firme forest in the eastern Amazon. This seed bank is described via community-level attributes across forest stands exposed to wildfires once or twice, as well as across unburned, old-growth forest stands. A total of 2345 seeds germinated (837.5 seeds/m²). Across all three f...
Article
The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending mone...

Nutrient dynamics directly influence forest productivity, yet their exploration in tropical dry forests, particularly in human-modified landscapes, is limited. We examine aboveground and soil carbon, nitrogen, and phosphorus concentrations and stocks in 19 stands across gradients of rainfall, chronic anthropogenic disturbances (CAD), aboveground bi...
Article
The ability of dry forests to deliver ecosystem services of both local and global relevance depends on the capacity of those forests to recover from constant disturbances in human-modified landscapes. Here we examine the effects posed by biomass, chronic human disturbances and aridity on the recovery of reproductive functional diversity by edible f...
Article
Tropical dry forest productivity is thought to be driven by a combination of natural factors, particularly total water availability and seasonality. However, most of the world's dry forests have been converted into forest successional mosaics by a combination of slash-and-burn agriculture and exploitation of forest products, which has potential imp...
Article
[Link to download: https://authors.elsevier.com/a/1iSDW1L%7EGwcLqj ]-- In environments under chronic human disturbance, the persistence of woody plants via both resprouting of new shoots and clonal growth via new root suckers can increase survival and fitness. However, the relative frequency and importance of these mechanisms following disturbance...
Article
Slash-and-burn agriculture is a common practice in dry forests worldwide. Understanding the relative importance of different regeneration mechanisms following this disturbance provides insights into forest regeneration dynamics and resilience. We assessed differences in structural components, the relative contribution of vegetative and sexual repro...

Pollination is a key ecosystem service of critical importance for food production. However, globally, several regions are already experiencing pollinator shortage as pollinators are declining. Here, we investigate the origin, pollinator dependence and economic value of 199 food crops cultivated in Brazil to understand to which extent (1) Brazilian...
Article
Seed rain is critical for forest recovery, especially in abandoned lands that have been exposed to agriculture. However, such a critical role depends on seed viability, which has been largely overlooked in most seed rain studies. We assessed the viability of 5378 seeds of 24 woody species in the seed rain falling into 12 plots from a Brazilian trop...

The exploitation of nontimber forest products has been proposed as a sustainable way to exploit tropical forests, but such an opportunity remains to be examined case‐by‐case. We examine the impact of the intensification of the açaí palm (Euterpe oleracea) management for fruit production via increments in palm clumps/stems density on the woody plant...
Article
Cropland intensification in tropical regions is usually associated with agricultural commodity expansion that penalizes the species diversity and environmental services of natural ecosystems. However, the extent to which cropland expansion affects the reproductive functional diversity of crop arrangements remains poorly investigated. Here we examin...
Article
The environment plays an important role in resource selection by human groups. For example, the same environment shared by different cultures tends to have a greater similarity of useful plants. The present study departs from an innovative perspective, analyzing the factors that influence species richness and their versatility and utilitarian redun...
Article
Full-text available
Wildfires have emerged as an escalating source of tropical forest degradation with a cascade of negative consequences for the sustainable development of tropical regions. This is particularly the case in the Amazon forest region as wildfires have already degraded a considerable extension of both secondary and old-growth forests, including "social f...

Tropical forest regeneration across old fields has been mainly described as a predictable sequence of functional plant assemblages in response to environmental filtering. However, the way plant reproductive diversity is organized along forest regeneration and how the reproductive profile of woody flora may impact regeneration have been poorly inves...
Article
Full-text available
Abandonment of agricultural lands promotes the global expansion of secondary forests, which are critical for preserving biodiversity and ecosystem functions and services. Such roles largely depend, however, on two essential successional attributes, trajectory and recovery rate, which are expected to depend on landscape-scale forest cover in non-lin...
Article
Forest's recovery potential in human-modified landscapes is increasingly threatened by agricultural activities that disrupt critical sources of forest regeneration, such as the seed rain. Slash-and-burn agriculture is a good example. By slashing and burning the vegetation, this farming method can promote seed source and seed dispersal limitation, b...
Article
Resprouting is a widespread mechanism through which woody plants recover from biomass loss and/or abiotic stress, particularly in fire-prone ecosystems. Here, we assess the resprouting responses to coppicing exhibited by woody plant species in a human-modified landscape of Caatinga dry forest, in the northeast of Brazil. A total of 150 resprouts...
