Abstract Questions Functional redundancy in assemblages may insure ecosystem processes after perturbation potentially causing temporary or permanent local species extinctions. Yet, functional has only been inferred by indirect evidence measured methods that not be the most appropriate. Here, we apply an existing method to measure redundancy, which is fraction of diversity expressed diversity, assess whether affects community resilience disturbance. Location Subtropical grassland, south B...
Abstract Question: Whereas similar ecological requirements lead to trait‐convergence assembly patterns (TCAP) of species in communities, the interactions controlling how associate produce trait‐divergence (TDAP). Yet, linking latter community processes has so far only been suggested. We offer a method elucidate TCAP and TDAP gradients that will help fill this gap. Method: evaluated correlation between trait‐based described communities gradients, using partial correlation, we separated...
Disturbances induce changes on habitat proprieties that may filter organism's functional traits thereby shaping the structure and interactions of many trophic levels. We tested if communities predators with foraging dependent respond to environmental change through cascades affecting plants. monitored response spider plant fire in South Brazilian Grasslands using pairs burned unburned plots. Spiders were determined family level described feeding behavioral morphological measured each...
Climate change is one of the main drivers species extinction in twentyfirst-century. Here, we (1) quantify potential changes species' bioclimatic area habitat (BAH) 135 native agroforestry from Brazilian flora, using two different climate scenarios (SSP2-4.5 and SSP5-8.5) dispersal scenarios, where have no ability to disperse reach new areas (non-dispersal) can migrate within estimated BAH (full dispersal) for 2041-2060 2061-2080. We then (2) assess preliminary conservation status each based...
(1) Brazil has great potential to expand the area under agroforestry, and thereby simultaneously enhance multiple ecosystem services. However, divergent interests are currently polarized between drastic environmental deregulation public resource allocation chemical-intensive land use versus conservation sustainable agriculture. This highlights an urgent need for a comprehensive overview of evidence benefits society generated by agroforestry across Brazil. (2) We present systematic map...
Abstract Edge effect is the modification of ecological patterns and processes that occur around edge two adjacent ecosystems. Depending on their aim, studies have adopted one following methodological approaches: (1) one‐sided approach—which from an to interior just habitats (2) two‐sided across whole gradient habitat other habitat, passing through zone. A database containing information 317 published papers revealed both approaches were equally used until end 1980s. During 1990s, question...
Abstract We still lack practical guidelines for diversifying cropping systems that consider both yield and regulating functions of agroecosystems. Recent studies have suggested maximizing functional diversity (FD, the distribution species with different traits in niche space) may lead to agroecosystems greater multifunctionality due complementarity. Therefore, scientists are now advocating use a trait‐based approach develop multifunctional sustainable In order assess effects crop FD on key...
Functional redundancy predicts that some species may play equivalent roles in ecosystem functioning therefore conferring a kind of ‘insurance’ to perturbation when richness is reduced, by the compensation same functional group on processes. We evaluate grassland plant communities removal experiment which evaluated treatments were: GG – clipping two graminoid species, FF forb GF one and Control no removal. tested hypothesis above‐ground biomass each would cause less change community...
Disturbances are primary forces creating spatial heterogeneity in ecosystems, and inducing changes on biological communities, abiotic characteristics ecological processes. Here we focus the effects of fire disturbance decomposition process at subtropical Campos grasslands South Brazil, where burns traditionally used to reduce shrub encroachment, improve forage quality. We experimentally investigated how they produce grassland habitat conditions affect soil fauna detritivory surface...
Abstract Questions Grasslands in subtropical Brazil are known as potentially fire‐prone ecosystems. Aiming to better understand the effects of fire on biodiversity, we addressed following questions: does benefit all alpha and beta components taxonomic functional diversity grasslands; which groups affected; foster recovery above‐ground biomass after fire? Location Campos grassland, southern Methods The were investigated using a before/after control/impact experimental design. A randomized...
Tree monocultures frequently have a negative impact on biodiversity; however, the adoption of ecologically‐sustainable management practices can produce different outcome. In this study we evaluate how replacement Araucaria Forest by affects abundance, age structure, sex ratio, and diet endemic frog Physalaemus lisei Braun andBraun(1977 Braun, P. C. A. S. 1977.

Abstract Designing multispecies systems with suitable climatic affinity and identifying species' vulnerability under human‐driven climate change are current challenges to achieve successful adaptation of natural systems. To address this problem, we need (1) identify groups species similarity scenarios (2) areas high conservation value predicted change. recognize similar niche requirements that can be grouped for mixed cropping in Brazil, employed ecological models (ENMs) Spearman's ρ...
Abstract Forecasting the impacts of climate change on species distribution has several implications for conservation. Plinia edulis is a rare and threatened tree from Brazilian Atlantic Rainforest. In this study, we assessed impact global P. edulis. Additionally, evaluated efficacy protected network to conserve species. Ecological niche models were built using maximum entropy method based occurrence records environmental predictors. Models predicted reduction climatically suitable areas in...
Maintaining the growth of agricultural production and reducing impacts this on natural resources has become one great challenges humanity. This research aims to characterize variation bird assembly between pastoral areas adjacent forest remnants, evaluating impact land use change birds diversity. study will also discuss methodology passive acoustic monitoring (MAP) for rapid assessment biodiversity in rural landscapes Atlantic Forest Biome. The data were collected two habitats (Forest...
Abstract Aims Escobedia grandiflora is a root hemiparasite from Central and South America, its orange roots are used as phytomedicine food coloring. Since hemiparasites America have not been extensively investigated, here, in the first study conducted on Latin American species, we investigated how affects structure diversity of plant communities four locations southern Brazil, all belonging to Atlantic Forest biome. Specifically, asked if presence would: (a) affect species composition; (b)...
