“…The relative importance of ecological niches and neutral processes in plant diversity has been debated (Blundo et al, 2016; Wang et al, 2019). Many studies have discussed the independent and common effects of ecological niches and neutral processes on plant diversity in different ecosystems (Li et al, 2021; Liu et al, 2015; Yakimov et al, 2020), but few studies have reported on whether the relative importance of ecological niches and neutral processes in desert ecosystems changes as diversity in different dimensions changes (Hu et al, 2021; Wang et al, 2019). Our results suggest that these diversities have inconsistent responses to the effects of ecological niches and neutral processes.…”

“…The Rao quadratic entropy (Rao Q), which was chosen as the functional α‐ diversity index, contains both a measure of the relative abundance of species and pairwise functional differences between species (Mason et al, 2012); it can be a good indicator of changes in functional traits in the community. The mean pairwise phylogenetic distance MPD index, which predicts the mean phylogenetic distance between all pairs of taxonomic units in a clustering tree (Webb et al, 2008), was chosen to illustrate the overall clustering of the evolutionary tree (Webb et al, 2002) Mean phylogenetic distance between species (MPD) is the most widespread metrics applied at the level of individual samples (α‐diversity) (Yakimov et al, 2020). Species, functional, and phylogenetic α‐diversity calculations were performed by the vegan, FD, and picante packages, respectively.…”

Understanding the spatial distribution of plant diversity and its drivers are major challenges in biogeography and conservation biology. Integrating multiple facets of biodiversity (e.g., taxonomic, phylogenetic, and functional biodiversity) may advance our understanding on how community assembly processes drive the distribution of biodiversity. In this study, plant communities in 60 sampling plots in desert ecosystems were investigated. The effects of local environment and spatial factors on the species, functional, and phylogenetic α‐ and β‐diversity (including turnover and nestedness components) of desert plant communities were investigated. The results showed that functional and phylogenetic α‐diversity were negatively correlated with species richness, and were significantly positively correlated with each other. Environmental filtering mainly influenced species richness and Rao quadratic entropy; phylogenetic α‐diversity was mainly influenced by dispersal limitation. Species and phylogenetic β‐diversity were mainly consisted of turnover component. The functional β‐diversity and its turnover component were mainly influenced by environmental factors, while dispersal limitation dominantly effected species and phylogenetic β‐diversity and their turnover component of species and phylogenetic β‐diversity. Soil organic carbon and soil pH significantly influenced different dimensions of α‐diversity, and soil moisture, salinity, organic carbon, and total nitrogen significantly influenced different dimensions of α‐ and β‐diversity and their components. Overall, it appeared that the relative influence of environmental and spatial factors on taxonomic, functional, and phylogenetic diversity differed at the α and β scales. Quantifying α‐ and β‐diversity at different biodiversity dimensions can help researchers to more accurately assess patterns of diversity and community assembly.

“…High elevation communities are often found to be phylogenetically clustered (where the species present in the local environment are more related than one would expect from a random draw of the regional species pool) (Vamosi et al 2009). The literature contains examples of this pattern revealed for vertebrates (Graham et al 2009, Montaño-Centellas et al 2020, invertebrates (Machac et al 2011, Hoiss et al 2012, Smith et al 2014, free-living bacteria (Wang et al 2012), endosymbiotic bacteria (Li et al 2019) and plants (Yakimov et al 2020). In most cases, this has been interpreted as evidence of an 'environmental filter' effect where only a lineage containing some (often untested) adaptation survived in this extreme environment.…”

Diversity and phylogenetic community structure across elevation during climate change in a family of hyperdiverse neotropical beetles (Staphylinidae)

Environmental stress from abiotic conditions imposes physiological limits on individuals within communities, and these stressful conditions can act as a filter on the species present in any given environment. Such abiotic stressors can reduce a community's diversity and make its composition more phylogenetically clustered. Using a decade of staphylinid beetle (Staphylinidae, Coleoptera, rove beetles) collections made across a 1500 m elevation gradient in northwestern Costa Rica (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017) we asked what species lived there, how large and overlapping were the communities across this gradient, and what relationship was there between elevation and diversity. Using DNA barcodes for identification and phylogenetic estimates of community structure, we found high turnover across elevation, and that staphylinid diversity increased linearly with elevation. Because of this, we found staphylinid diversity was negatively related to surface area and temperature, and positively with precipitation. We suggest that historical biogeography and contemporary environmental stress have combined to produce these observed patterns. The forests in which these beetles are found are heating and drying rapidly and our finding that diversity increases with elevation suggests that there will be catastrophic biodiversity loss in the coming decades.

“…where MPD sam is the observed mean phylogenetic distance, and MNTD sam is the observed mean nearest taxon distance between all possible pairs of taxa in each plot. MPD rnd and MNTD rnd represent the mean MPD and mean MNTD of randomized assemblages, in which species in a plot are selected randomly from the species pool 999 times to obtain a distribution of MPD and MNTD for the random null model [16]. sd(MPD rnd ) and sd(MNTD rnd ) are the standard deviations of MPD rnd and MNTD rnd .…”

“…Some studies have considered a connection between αand β-diversity at the level of phylogenetic structure [14,15]. Non-random patterns of phylogenetic diversity may influence the spatial transformation of phylogeny and provide additional information for explaining mechanisms of community assembly [16]. Measures of phylogenetic diversity can take Faith's PD, which is the sum of lengths of branches spanning that subset on the tree [17], and distance among species into account, and provide a means of quantifying the phylogenetic community structure in space.…”

Studying community assembly has always been a central issue in ecological research and is necessary for understanding mechanisms of species coexistence and biodiversity. Environmental heterogeneity is a driver of biodiversity, but much remains to be learned about how evolutionary processes are affected by environmental factors. We aimed to clarify the evolutionary processes in different vegetation communities in the Huangshan Scenic Area, Anhui Province, China. We constructed a phylogenetic tree of these communities based on a constraint tree and three DNA barcode regions. Community I was characterized by a weakly overdispersed phylogenetic structure for all three plant groups. The structure of Community II showed clustered for total plants and shrubs, overdispersed for trees. However, the phylogenetic structure was clustered for total plants, overdispersed for trees and shrubs in Community III. The main drivers of these patterns were spatial and climatic factors. Phylogenetic α-diversity had a significant positive relationship with species richness. The values of phylogenetic β-diversity reached their maximum at intermediate elevationsamong three vegetation communitiesfor total plants. The main factors that affected diversity patterns were spatial variables, not climatic factors, indicating that environmental heterogeneity determined the mechanisms of biodiversity and species coexistence in the community. Our results showed that deterministic processes may control community assembly in three different vegetation regions.
