“…Organic pollution (such as measures as COD Mn ) was also proved to be an important factor for the distribution of lotic organisms in the Chishui River (Chi et al, 2017;Mao et al, 2018). In addition, suitable current velocity conditions can provide resources (Schoen, Merten, & Wellnitz, 2013) and control sediment compositions (Fenoglio, Boano, Bo, Revelli, & Ridolfi, 2013) for certain species, thereby shaping the composition and abundance of macroinvertebrate communities in the Chishui River (Wang et al, 2018). For benthic diatoms, environmental filtering through physicochemical factors drove community assembly in both seasons.…”

Identifying seasonal shifts in community assembly for multiple biological groups is important to help enhance our understanding of their ecological dynamics. However, such knowledge on lotic assemblages is still limited. In this study, we used biological traits and functional diversity indices in association with null model analyses to detect seasonal shifts in the community assembly mechanisms of lotic macroinvertebrates and diatoms in an unregulated subtropical river in China. We found that functional composition and functional diversity (FRic, FEve, FDis, MNN, and SDNN) showed seasonal variation for macroinvertebrate and diatom assemblages. Null models suggested that environmental filtering, competitive exclusion, and neutral process were all important community assembly mechanisms for both biological groups. However, environmental filtering had a stronger effect on spring macroinvertebrate assemblages than autumn assemblages, but the effect on diatom assemblages was the same in both seasons. Moreover, macroinvertebrate and diatom assemblages were shaped by different environmental factors. Macroinvertebrates were filtered mainly by substrate types, velocity, and COD Mn , while diatoms were mainly shaped by altitude, substrate types, and water quality. Therefore, our study showed (a) that different biological assemblages in a river system presented similarities and differences in community assembly mechanisms, (b) that multiple processes play important roles in maintaining benthic community structure, and (c) that these patterns and underlying mechanisms are seasonally variable. Thus, we highlight the importance of exploring the community assembly mechanisms of multiple biological groups, especially in different seasons, as this is crucial to improve the understanding of river community changes and their responses to environmental degradation.

“…Thus, the possible hotspots of this topic should be focused on them in further studies because of many advantages of them. Using multiple facets of biodiversity measures could reflect the comprehensive variation of community diversity (Cai, Zhang, Xu, & Heino, ; Heino & Tolonen, ; Wang et al, ). Particularly, functional traits and the proposed functional diversity indices (Mason, Mouillot, Lee, & Wilson, ; Villéger, Mason, & Mouillot, ) directly link the performance of organisms to the environment (see Lavorel, McIntyre, Landsberg, & Forbes, ; Wieczynski et al, ), which could reflect disturbance processes, nutrient cycling, energy flow, and biotic interactions (Ward & Tockner, ).…”

Aim The interspecific relationships between species occupancy and abundance have been broadly studied in terrestrial systems; however, the causes underlying this relationship in freshwater fishes remain poorly addressed. The main aims of this study were (a) to examine the occupancy–abundance relationship in 62 fish species in a monsoon climate river; (b) to determine the relative importance of species niche, functional traits and phylogenetic relatedness in shaping the occupancy–abundance relationship. Location The Chishui River, the Yunnan‐Guizhou Plateau and the Szechwan Basin, China. Taxon Freshwater fishes. Methods A linear model was used to test the relationship between distribution and mean abundance across fish species. The outlying mean index analysis was performed to estimate niche breadth and niche position parameters for each fish species. In addition, using principal coordinates analysis, we created four trait vectors describing the similarity of species' traits. Fish phylogeny was obtained from a global molecular phylogenetic tree of actinopterygian fishes. We used a combination of linear models, commonality analyses and boosted regression trees to evaluate the relative effects of the niche metrics, traits and phylogenetic relatedness on occupancy and abundance. Results Fish occupancy was strongly (R2 = 0.749) and positively correlated with mean abundance in the Chishui River. Niche parameters, especially niche position, were the main determinants of variation in occupancy (e.g. total contribution of niche position and breadth using commonality analyses: 0.587 and 0.318) and abundance (0.323 and 0.151) across species. Furthermore, traits and phylogeny had little to no effect on fish occupancy (0.034 and 0.037) and abundance (0.021 and 0.003). Main conclusions Freshwater fishes in the Chishui River fit the common macroecological pattern of positive relationship between occupancy and abundance. Niche parameters, but not traits and phylogeny, are the primary correlates of riverine fish distribution and abundance.
