Abstract Land‐cover change and ecosystem degradation may lead to biotic homogenization, yet our understanding of this phenomenon over large spatial scales different groups remains weak. We used a multi‐taxa dataset from 335 sites 36 heterogeneous landscapes in the Brazilian Amazon examine potential for landscape‐scale processes modulate cumulative effects local disturbances. Biotic homogenization was high production areas but much less disturbed regenerating forests, where levels among‐site...
Quantifying and understanding the main drivers of biodiversity responses to human disturbances at multiple scales is key foster effective conservation plans management systems. Here we report on a detailed regional assessment response ant communities land-use change forest disturbance in Brazilian Amazon. We aimed explore effects intensification both site landscape scales, examining variation species richness composition, asking which set environmental variables best predict observed...
Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): multidisciplinary research initiative involving than 30 partner organizations working assess both social and ecological dimensions of land-use sustainability eastern Brazilian Amazonia. The approach adopted by RAS offers three advantages for addressing problems: (i) collection synchronized co-located socioeconomic data...
Secondary forests (SFs) regenerating on previously deforested land account for large, expanding areas of tropical forest cover. Given that rank among Earth's most important reservoirs carbon and biodiversity, SFs play an increasingly pivotal role in the cycle as potential habitat biota. Nevertheless, their capacity to regain biotic attributes undisturbed primary (UPFs) remains poorly understood. Here, we provide a comprehensive assessment SF recovery, using extensive biomass, environmental...
Consider both water and land When designing terrestrial reserves, it is common to consider the needs of species systems from a perspective, with an assumption that any freshwater will benefit as well. Leal et al. tested this by analyzing data two locations in Brazilian Amazon found far accurate: Terrestrial confer little (see Perspective Abell Harrison). However, authors also integrating into overall reserve planning increased benefits 600% while only decreasing outcomes 1%. They argue must...
Abstract Aim The two main hypotheses about the Neotropical palaeovegetation, namely that of Amazonian refugia by Haffer and Pleistocene arc Prado Gibbs, are still constantly debated. We offer new insights on this debate using ecological niche modelling with combined climate–soil predictors to test both hypotheses, reconstruct palaeovegetation Last Glacial Maximum (LGM; 21 ka) Mid‐Holocene (Mid‐H; 6 indicate configuration areas. Location Brazil. Time period ka. Major taxa studied Biomes....
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...
Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. The undeniable importance conserving tropical forests has drawn most the conservation spotlight towards it. However, open such as Brazilian Campo Rupestre (rupestrian grassland), have been historically overlooked despite their high diversity key associated ecosystem services. We highlight major current threats...
Recent studies have argued that changes in fire regimes the 21st century are posing a major threat to global biodiversity. In this scenario, incorporating species’ physiological, ecological, and evolutionary traits with their local exposure might facilitate accurate identification of species most at risk from fire. Here, we developed framework for identifying animal vulnerable extinction fire-induced stress Brazilian savanna. The proposed addresses vulnerability two components: (1) exposure,...
Complex environmental issues require solutions that cannot be achieved without integrating scientific disciplines and communicating science to people, decision-makers stakeholders. Nevertheless, although Alexander von Humboldt gifted us with an approach integrate knowledge across aiming broadly understand issues, our current practice largely ignores holistic approach. Here, we develop a conceptual framework for sustaining mountain integrity securing their ecosystem services based on...
Abstract We investigated the patterns of taxonomic (TD) and functional (FD) α β‐diversities ants in a mountainous landscape along three dimensions, namely one temporal (seasonal) two spatial dimensions: between habitats – grassland forest (horizontal), among elevation bands (vertical). In addition, we tested effects environmental variables (mean temperature, normalised difference vegetation index NDVI) on α‐ β‐diversities. β diversities dimensions are main components TD. Conversely, FD is...
Cocoa beans used for chocolate production are fermented seeds of Theobroma cacao obtained by a natural fermentation process. The flavors and chemical compounds produced during the process make this step one most important in fine production. Herein, an integrative analysis variation microbial community structure, using shotgun metagenomics approach associated physicochemical features, was performed cocoa beans. Samples Forastero variety (FOR) mixture two hybrids (PS1319 CCN51) (MIX) from...
The evaluation of the success restoration efforts is an essential step for environmental monitoring programs, providing reliable and intricate information on response biotic abiotic elements ecosystem following programs adopted. aim this study was to evaluate efficacy different rehabilitation after gold mining activities using ants as bioindicators. We tested hypotheses: (1) ant species richness composition vary with technique revegetation (2) number epigaeic hypogaeic increases resources....
Abstract In the last decades, due to human land management that uses fire as a tool, and abnormal droughts, many tropical forests have become more susceptible recurrent wildfires with negative consequences for biodiversity. Yet, studies are usually focused on few taxa rarely compare different frequencies. We examined if effects of single fires consistent leaf litter ants, dung beetles, birds (sampled point‐counts PC mist net‐ MN ), saplings, trees. Recurrent had great effect forest...
Abstract Mountains harbor rich biodiversity and high levels of endemism, particularly due to changes in environmental conditions over short spatial distances, which affects species distribution composition. Studies on mountain ecosystems are increasingly needed, as mountains highly threatened despite providing ecosystem services, such water supply for half the human population. We aimed understand patterns drivers alpha beta diversities aquatic invertebrates headwater streams along an...
