Summary Increasingly, ecologists are using functional and phylogenetic approaches to quantify the relative importance of stochastic, abiotic filtering biotic processes shaping pattern species co‐occurrence. A remaining challenge in analyses tropical tree communities is successfully integrate structure across spatial size scales habitats a single analysis. We analysed assemblages 20‐ha forest dynamics plot south‐west China. Because influence interactions may become more apparent as cohorts...
Abstract Using DNA barcoding for species identification remains challenging many plant groups. New sequencing approaches such as complete plastid genome may provide some increased power and practical benefits beyond standard barcodes. We undertook a case study comparing to discrimination in the ecologically economically important family Lauraceae, using 191 genomes 131 from 25 genera, representing largest plastome data set Lauraceae date. found that sequences were useful correcting errors...
Abstract Ecology cannot yet fully explain why so many tree species coexist in natural communities such as tropical forests. A major difficulty is linking individual-level processes to community dynamics. We propose a combination of spatial data, statistics and dynamical theory reveal the relationship between patterns population-level interaction coefficients their consequences for multispecies dynamics coexistence. Here we show that emerging have, broad range circumstances, simpler structure...
Lauraceae are an important component of tropical and subtropical forests have major ecological economic significance. Owing to lack clear-cut morphological differences between genera species, this family is ideal case for testing the efficacy DNA barcoding in identification discrimination species genera. In study, we evaluated five widely recommended plant barcode loci matK, rbcL, trnH–psbA, ITS2 entire ITS region 409 individuals representing 133 12 from China. We tested ability distinguish...
Abstract The relative degree to which stochastic and deterministic processes underpin community assembly is a central problem in ecology. Quantifying local-scale phylogenetic functional beta diversity may shed new light on this problem. We used species distribution, soil, trait data quantify whether environmental distance, geographic distance or their combination are the strongest predictors of local scales 20-ha tropical seasonal rainforest dynamics plot southwest China. patterns were...
Environmental filtering consistently shapes the functional and phylogenetic structure of species across space within diverse forests. However, poor descriptions community lineage distributions hamper accurate understanding coexistence mechanisms. We combined environmental variables geographic to explore how traits lineages are filtered by factors using extended RLQ fourth-corner analyses different spatial scales. The dispersion patterns were also examined in a 20-ha tropical rainforest...
Species in transitional areas often display adaptive responses to climate change and such may be crucial for long-term biodiversity conservation. Evaluation of spatial multidimensional patterns the identification hotspots priority conservation help mitigate effects change. Here, we examine distribution patterns, evolutionary functional levels Lauraceae from Chinese evergreen broad-leaved forests. The results show species richness (SR), corrected weighted endemism (CWE), phylogenetic...
AimsWhile using phylogenetic and functional approaches to test the mechanisms of community assembly, traits often act as proxy niches. However, there is little detailed knowledge regarding correlation between tree species their niches in local communities. We suggest that co-varying should be premise for assembly. Using traits, environmental data, this study aims answer questions: (i) within communities, do co-occurring co-vary with at level? (ii) what key ecological process underlying...
Abstract Conspecific negative density dependence ( CNDD ) has been recognized as a key mechanism underlying species coexistence, especially in tropical forests. Recently, some studies have reported that seedling survival is also negatively correlated with the phylogenetic relatedness between neighbors and focal individuals, termed PNDD ). In contrast to or , shared habitat requirements closely related individuals are thought be cause of observed positive effects neighbors, which may affect...
Abstract The niche theory predicts that environmental heterogeneity and species diversity are positively correlated in tropical forests, whereas the neutral suggests stochastic processes more important determining diversity. This study sought to investigate effects of soil nutrient (nitrogen phosphorus) on tree Xishuangbanna seasonal rainforest southwestern China. Thirty‐nine plots 400 m 2 (20 × 20 m) were randomly located rainforest. Within each plot, availability heterogeneity, diversity,...
Abstract Understanding the role of climate changes and geography as drivers population divergence speciation is a long‐standing goal evolutionary biology can inform conservation. In this study, we used restriction site‐associated DNA sequencing (RAD‐seq) to evaluate genetic diversity, structure, infer demographic history endangered tree, Phoebe zhennan which distributed around Sichuan Basin. Genomic patterns revealed two distinct clusters, each largely confined West East. Despite sympatry...
Abstract The lasting imprint of phylogenetic history on current day ecological patterns has long intrigued biologists. Over the past decade ecologists have increasingly sought to quantify signals in environmental niche preferences and, especially, traits help uncover mechanisms driving plant community assembly. However, relatively little is known about how niches and compare, leaving significant uncertainty implications trait-based analyses. We examined within 64 species, at seedling adult...
Abstract The majority of species in many communities are rare, and it is an enduring challenge to understand the mechanism rarity commonness local communities. niche partitioning hypotheses posit that common occupy wide core positions, while rare narrow outlying positions. We test these here, simultaneously considering both environmental a functional perspective on niches. examined how niches correlate with abundance space by quantifying relationships between width position. Environmental...
Accurate identification of species from timber is an essential step to help control illegal logging and forest loss. However, current approaches based on morphological anatomical characteristics have limited resolution. DNA barcoding a proven tool for plant identification, but there need build reliable reference data across broad taxonomic spatial scales. Here, we construct library consisting 1550 taxonomically diverse 656 genera 124 families, representing comprehensive genetic set Chinese...
Abstract The biologist's ruler for biodiversity is the species; accurate species identification fundamental to conservation of endangered and in‐depth biological scientific exploration. However, delimitation affinities Horsfieldia in China has been controversial, owing part very low levels molecular divergence within family Myristicaceae. Because boundaries phylogenetic relationships are also unclear, 13 samples were collected across its distribution their genomes subjected shotgun...
Abstract Species delimitation remains a challenge worldwide, especially in highly diverse tropical and subtropical regions. Here, we use an integrative approach that combines morphology, phylogenomics, species distribution modeling (SDM) to clarify the cryptic differentiation within enigmatic hemiparasitic love vine Cassytha filiformis (Lauraceae) China adjacent We generated complete plastid genomes nuclear ribosomal sequences for samples from across range compared results with previously...
Understanding the maintenance of biodiversity and community assembly is a central issue in ecology. Here, we examined patterns phylogenetic structure subtropical forests along an elevational gradient Ailao Mountains southwest China.

Abstract The aim of DNA barcoding is to enable fast and accurate species identification. However, universal plant barcodes often do not provide species-level discrimination, especially in taxonomically complex groups. Here we use Lauraceae for the design evaluation strategies, considering: (1) efficacy taxon-specific barcode regions compared with discrimination; (2) how extent intra- interspecific sampling affects discrimination rates. To address these areas, targeted highly polymorphic,...
