Abstract Summary: SYNCSA is an R package for the analysis of metacommunities based on functional traits and phylogeny community components. It offers tools to calculate several matrix correlations that express trait-convergence assembly patterns, trait-divergence patterns phylogenetic signal in at species pool level metacommunity level. Availability implementation: a environment, under GPL-2 open-source license freely available CRAN official web server (http://cran.r-project.org). Contact:...
Virtually all empirical ecological interaction networks to some extent suffer from undersampling. However, how limitations imposed by sampling incompleteness affect our understanding of is still poorly explored, which may hinder further advances in the field. Here, we use a plant-hummingbird network with unprecedented effort (2716 h focal observations) Atlantic Rainforest Brazil, investigate affects description structure (i.e. widely used metrics) and relative importance distinct processes...
Abstract Species are entangled within communities by their interactions in such a manner that local extinction may unchain coextinction cascades and impact community dynamics stability. Despite increasing attention, simulation models to estimate the robustness of interaction networks largely neglect important role rewiring, is, ability species switch partners. Here we propose new method incorporate potential replace lost partners into widely used model network robustness. In this model,...
Abstract Questions What is the magnitude of between‐species trait variability ( BSV ) and within‐species WSV specific leaf area SLA in a sapling meta‐community? To what extent do species turnover influence community‐level mean responses to an environmental gradient spread patterns across this gradient? role for plant variation niche partitioning structuring communities? Location Forest patches within native grassland matrix southern Brazil. Methods We recorded saplings community plots canopy...
Summary Metacommunity phylogenetics aims at evaluating environmental and/or historical factors driving clade distribution. Phylogenetic fuzzy weighting ( PFW ) describes distribution across metacommunities based on sets defined by phylogenetic relatedness among species. The method enables analysing biogeographic determinants of also offers an exploratory tool for visualizing via Principal Coordinates Structure PCPS ). In this article, we describe the theoretical properties and biological...
Abstract Functional traits mediate ecological responses of organisms to the environment, determining community structure. Community‐weighted trait means ( CWM ) are often used characterize communities by combining information on species and distribution. Relating variation environmental gradients allows for evaluating sorting across metacommunity, either based correlation tests or ordinary least squares OLS models. Yet, it is not clear if phylogenetic signal in both distribution affect those...
Abstract Functional traits are commonly used in predictive models that link environmental drivers and community structure to ecosystem functioning. A prerequisite is identify robust sets of continuous axes trait variation, understand the ecological evolutionary constraints result functional space occupied by interacting species. Despite their diversity role functioning, little known on invertebrate biotas entire biogeographic regions. We examined strategies underlying realized aquatic...
Background We evaluated the direct and indirect influence of climate, land use, phylogenetic structure, species richness endemism on distribution New World threatened amphibians. Methodology/Principal Findings used WWF's ecoregions, WWFs amphibian distributional data IUCN Red List Categories to obtain number per ecoregion. analyzed three different scenarios urgent, moderate, most inclusive scenario. Using path analysis we effects type amphibians in ecoregions. In all found strong support for...
Abstract Aim Speciation, extinction and historical dispersal are the ultimate factors generating maintaining biodiversity. However, methods of macroevolution used to detect processes usually ignore variation macroevolutionary at scales finer than entire regions. Likewise, biogeography community ecology often deep‐time evolutionary processes. To overcome this problem, it is necessary integrate data from ancestral state reconstructions, current species distributions biogeographical...

Despite great interest in metrics to quantify the structure of ecological networks, effects sampling and scale remain poorly understood. In fact, one most challenging issues ecology is how define suitable scales (i.e., temporal or spatial) accurately describe understand systems. Here, we sampled a series ant-plant interaction networks southern Brazilian Amazon rainforest order determine whether spatial scale, from local regional, affects our understanding these networks. To this end,...
This study assessed the impact of altitude, precipitation, and soil conditions on species richness (SR), phylogenetic diversity (PD), functional (FD) standardized effect sizes in subtropical Brazilian Atlantic Forest tree communities. We considered specific trait information (FDs) for FD, reflecting recent adaptive evolution, contrasting with deeper constraints FD. Three traits (leaf area-LA, wood density-WD, seed mass-SM) were examined their response to these gradients. Generalized least...
Abstract The evolution of a particular trait or combination traits within lineages may affect subsequent evolutionary outcomes, leading closely related species to exhibit higher phenotypic similarity than expected under simple B rownian‐motion model. Niche theory postulates that phenotypes determine distribution across environmental gradients, phylogenetic signature in the community assembly. Thus, incorporation phylogeny analysis ecology structure allows one link broader environmental,...
Abstract Understanding how species traits evolved over time is the central question to comprehend assembly rules that govern phylogenetic structure of communities. The measurement signal ( PS ) in ecologically relevant a first step understand phylogenetically structured community patterns. different methods available estimate make it difficult choose which most appropriate. Furthermore, alternative tree hypotheses, node resolution and clade age estimates might influence measurements. In this...
Abstract Aim Disentangling the effects of climate and historical factors on biodiversity distribution remains a challenge for biogeographers. Here, we provide an analytical framework to discriminate contributions contemporary biogeographical history taxa geographical distributions phylogenetic lineages. Furthermore, evaluate constraint that clades exerts association between clade distribution, i.e. legacy climatic effects. As case study, analysed amphibian lineages across A mericas. Location...
Summary Understanding cascading effects of species loss is a major challenge for ecologists. Traditionally, the robustness ecological networks has been evaluated based on simulation studies where primary extinctions occur at random or as function specialization, ignoring other important biological factors. Here, we estimate seed dispersal network from grassland–forest mosaic in southern Brazil, simulating distinct scenarios woody plant extinction, including are eliminated their evolutionary...
Background: Araucaria forests are mountain ecosystems that might have expanded in the late Holocene, however past distributions remain uncertain. If current distribution reflects climatic conditions, and future may be projected using climate models.Aims: To contribute to understanding of as a function climate, we hypothesised (1) they increased their geographic since Last Glacial Maximum (LGM) until present; (2) would contract under predicted climates.Methods: We modelled spatial current,...
Abstract Question Climate change induces shifts in species distributions, ultimately changing community composition. Mountains are especially sensitive to climate change, and tree predicted move towards higher elevations, but observed changes not always unidirectional. The diversity complexity of tropical subtropical systems limits our understanding climate‐induced responses mountain forests. Here, we investigated migration trends composition along an elevational gradient, between the...
