Abstract Plant traits – the morphological, anatomical, physiological, biochemical and phenological characteristics of plants their organs determine how primary producers respond to environmental factors, affect other trophic levels, influence ecosystem processes services provide a link from species richness functional diversity. Trait data thus represent raw material for wide range research evolutionary biology, community ecology biogeography. Here we present global database initiative named...
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...
It is well known that species evolutionary history plays a crucial role in community assembly. Here, we offer formal analytical framework to integrate metacommunity analysis the species' phylogeny with their functional traits and abundances. We define phylogenetic structure of as phylogenetically weighted composition. This used reveal patterns variation measure test by specified null models signal at level, which distinguish from pool level. The former indicates communities more similar are...
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...
Abstract Araucaria Forest expansion over grassland takes place under wet climate conditions and low disturbance it is hypothesized that isolated trees established on facilitate the establishment of forest woody species beneath their canopies. with angustifolia a particular type Brazilian Atlantic main highland plateau in south Brazil, often forming mosaics natural Campos grassland. The objectives this paper were to evaluate role shrubs as colonization sites for seedlings grassland, determine...
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...
It is widely perceived how research institutes have been adopting the discourse of champions diversity, inclusion, and equity (DEI) in recent years. Despite progress diversity inclusion academic environment, we highlight here that nothing or, at very best, little work has done to overcome scientific labor division promotes neocolonial practices recognition jeopardizes equity. In this piece, bring secondary data reinforce biased patterns between Global North South (geographical markers...
Because species–environment interactions are mediated by phenotypic tradeoffs, the maintenance of ancestral traits in some phylogenetic clades and emergence evolutionary novelties others likely to limit types habitats that species occupy, generating habitat filtering. To test for filtering woody sapling communities vegetation patches scattered southern Brazilian grasslands, I estimated if different sizes encompassed groups. analyzed patch composition with principal coordinates structure...
The rapid global decline of amphibian population is alarming because many occur for apparently unknown or enigmatic reasons, even inside protected areas (PAs). Some studies have predicted the effects climate change on amphibians’ distribution and extinction, but relationship consequences to phylogenetic structure assemblages remain obscure. By applying robust techniques ecological niche modeling a cutting‐edge approach community phylogenetics, here, we evaluate how affects geographical...
Phylobetadiversity is defined as the phylogenetic resemblance between communities or biomes. Analyzing phylobetadiversity patterns among different vegetation physiognomies within a single biome crucial to understand historical affinities them. Based on widely accepted idea that forest Southern Brazilian Atlantic Forest constitute facies of biome, we hypothesize more recent nodes should drive gradients types Forest, divergence those biogeographically recent. We compiled information from 206...
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?

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...
Evidence of phylogenetic conservatism in plant ecological traits has accumulated over the past few years, suggesting an interplay between distribution clades and major environmental gradients. Nonetheless, determining what factors underlie lineages remains a challenge because are correlated with spatial gradients where latter might indicate some degree dispersal limitation pools. We analyzed structure assemblages across Brazilian Araucaria forests assessed how responds to compiled data on...
Questions: Do small rocky outcrops favor forest plant colonization and establishment in grasslands? If so, what are the potential mechanisms involved this process? Location: Araucaria Campos grassland mosaic southern Brazilian highlands (29°29′S, 50°12′W). Methods: We collected data on density of woody species plots located open fields subject to different management regimes. evaluated influence plants ≤60-cm tall, effects other environmental variables site density; we also used information...
Abstract Aim Body size variation in animal assemblages is a widely addressed pattern biogeographical studies, and affected by both environmental gradients phylogenetic constraints. However, no study has yet explored to what extent the association between body across broad spatial scales influenced distribution of different lineages. In this study, we discriminate influences variables community composition on South American sigmodontine rodents. Location America. Methods We computed mean mass...
Abstract Environmental gradients consist of sequential changes in the physical and structural characteristics a region. These allow us to follow species responses tolerances under different habitat conditions. Among them, forest fragmentation succession comprise most common examples gradients, where organismal require distinct morphological, physiological, behavioral adaptations. However, environmental can impose ecological evolutionary constraints that act on traits, as well local...
The role of Brazilian pine (Araucaria angustifolia) in the process forest succession is a topic increasing controversy. While some authors consider species to be pioneer, others it climax relict temperate forests. We designed field experiment assess light availability on regeneration A. angustifolia. following three forests, with contrasting patterns regeneration, were selected at National Forest southern Brazil: Pinus plantation, an Araucaria plantation and native araucarian forest....
