“…As we expected, different dimensions of beta diversity showed various responses to the focal ecological factors, as also found in previous studies conducted in lentic (Heino and Tolonen 2017;Fu et al 2019) and lotic ecosystems (Li et al 2019; Peláez and Pavanelli 2019). Our results showed that both taxonomic and phylogenetic beta diversities were mainly contributed by turnover, and were more strongly affected by spatial factors (i.e., dispersal limitation).…”

“…This also makes functional structure comparable across multiple geographical zones that differ in their taxonomic and phylogenetic compositions (Heino and Tolonen 2017). Contrary to the taxonomic and phylogenetic dimensions that were mainly contributed by their respective turnover components, functional beta diversity contained a relatively large nestedness component, as was also found in other related studies (Fu et al 2019; Rocha et al 2019). This finding may occur because different sites are characterized by distinct environmental heterogeneity, so that assemblages with low trait diversity occurring at less heterogeneous sites are likely to be subsets of the high trait diversity assemblages that exist in highly heterogeneous sites (Rocha et al 2019).…”

“…However, species metrics largely ignore the differences in morphological, physiological, and ecological features, as well as evolutionary relationships among species (Cardoso et al 2014), which cannot fully reveal the underlying mechanisms of community assembly and biodiversity maintenance (Meynard et al 2011; Hill et al 2019). Recently, with the development of functional ecology and molecular systematics, community ecologists and conservation biologists have recognized the importance of integrating multiple aspects of biodiversity, involving not only species identities but also functional and phylogenetic information in the analysis of biodiversity patterns in the freshwater realm (Cai et al 2019; Fu et al 2019; Roa‐Fuentes et al 2019).…”

Environmental filtering and spatial processes have been associated with variation in ecological communities and biodiversity; however, their relative importance on multiple dimensions of beta diversity has not been fully explored in montane streams. Here, we examined the relative contribution of local, catchment and climate environmental variables and spatial factors to variation in three dimensions of macroinvertebrate beta diversity in the upper Han River Basin. Taxonomic, functional, and phylogenetic beta diversities and their respective turnover and nestedness components were calculated for macroinvertebrate assemblages sampled in a total of 130 stream sites across a large mountainous landscape. We investigated the correlations between beta diversity facets using MSR-Mantel procedure and then examined the relative influence of each set of ecological factors through redundancy analysis and variance partitioning. Our results revealed relatively low spatial congruence among beta diversity dimensions, indicating these diversity dimensions are independent measures which offer complementary information of community assembly. Beta diversity dimensions and components were best explained by spatial and local environmental factors, whereas the large-scale catchment and climate factors appeared less influential. Moreover, spatial and environmental factors generally exerted different controls on beta diversity depending on the dimensions under consideration. Taxonomic and phylogenetic beta diversities were more strongly determined by spatial factors via dispersal limitation, while functional beta diversity was mainly associated to local environments through habitat filtering. Our results challenge the perspective that using one diversity facet as a surrogate for others is enough, and highlight the need to integrate multiple diversity dimensions in metacommunity and biodiversity research.

“…Our results complement and generally support the findings of three recent studies of β‐diversity in freshwater communities at medium to large scales (Bertuzzi, Pires, & Maltchik, 2019; Fu et al., 2019; Viana et al., 2015), but not those of Alahuhta, Kosten, et al (2017) for environmental influences on global β‐diversity of lake macrophytes. This last study, however, had a very small representation of tropical lakes (only 21 such waterbodies, all located in a single tropical area, the Amazon Basin, were included out of a total of 3,833 in their dataset), so the latitudinal database from which their conclusions were drawn was rather skewed.…”

“…The mean values of 12 environmental variables for each lake are shown in Table S1: water depth, lake altitude, lake area, lake volume, mean water depth, maximum water depth, Secchi depth, total nitrogen concentration, total phosphorus concentration, Chlorophyll‐a (Chl_a) concentration, water pH, and water temperature. The seven variables (i.e., colonization depth, lake altitude, lake area, lake volume, mean water depth, maximum water depth, and water temperature) were collected from local literature and measured at lake scale, whereas the other five variables (Secchi depth, total nitrogen concentration, total phosphorus concentration, Chl_a concentration, and water pH) were measured at plot scale (Fu et al, , ). For each sampling plot, a water sample was collected 0.5‐m below the water surface and then kept at 4°C for further chemical analysis.…”

Environmental variations are rapidly altering plant species and functional composition, which may have consequent influences on ecosystem functioning. We measured species and functional diversity of macrophyte community as well as environmental variables in 1,008 plots in 24 freshwater lakes across Yunnan-Guizhou plateau and Yangtze River in south China. We used generalized multilevel path models to test how the environmental effects on macrophytes productivity directly and indirectly through changes in species and functional diversity. We found distinct species and functional responses to the four groups of environmental variables:water quality, heterogeneity, climate, and topography. Macrophyte communities tended to be high richness and dominated by species with high-stem dry mass content and long flowering duration at eutrophic, heterogeneous, high altitude, or deepwater habitats.Submersed and annual species with high-specific leaf area dominated in heterogeneous and high altitude conditions, whereas species with high shoot and leaf dry mass content as well as thin stem and lamina dominated in heterogeneous and lowaltitude conditions. Functional dispersion (FDis) decreased in heterogeneous and high-altitude habitats and increased at deepwater. These changes in functional composition have subsequently significant influences on community productivity, involving the opposite pathways of positive effects of community-weighted mean (CWM) traits and negative effects of FDis, ultimately contributing to the observed invariable macrophytes productivity along the tested environmental gradients. Our results provide strong evidences that both species and functional composition mediate the cascading effects of environments on macrophytes productivity.
