“…However, a random pattern rather than functional clustering was observed, indicating that stochasticity and ecological drift are the primary processes regulating fish trait composition. The effects of stochastic processes on community structure have been found in previous studies on macroinvertebrates and diatoms in the Chishui River basin (Wang et al., 2020), fishes, macroinvertebrates, and macrophytes in the Yangtze River (Jia et al., 2021; Li et al., 2023; Liu & Wang, 2018) and other taxa in terrestrial landscapes (Cadotte et al., 2019; Si et al., 2017). We, therefore, upheld the idea that deterministic processes and stochasticity work together in governing fish community assembly, which only partially supported our second hypothesis (H2).…”

AimUnderstanding the patterns and drivers of biodiversity across space and time is commonly based on species diversity, which may ignore species' functional role and evolutionary history and result in an incomplete understanding of community assembly. It is suggested that integrating species, functional, and phylogenetic diversity could provide a more holistic assessment of community assembly in natural ecosystems. This study aimed to explore the elevational patterns and environmental drivers of multiple facets of fish diversity and community structure in a subtropical river during the wet and dry seasons.LocationThe Chishui River basin, China.MethodsWe investigated the responses of fish species richness, functional richness, and phylogenetic diversity to elevation in different seasons. Moreover, we compared functional dispersion and mean pairwise distance with those obtained from null models to infer assembly mechanisms shaping community structure. Additionally, we examined the environmental drivers (e.g. water chemistry, temperature, and river size) of fish diversity and community structure.ResultsFish species richness, functional richness, and phylogenetic diversity showed a negative relationship with elevation in the Chishui River basin. Fish communities tended to be on average functionally random but phylogenetically clustered. Furthermore, phylogenetic structure exhibited a decreasing pattern along the elevational gradient. Despite no significant seasonal changes for fish diversity (except for phylogenetic diversity), fish communities became more phylogenetically overdispersed and clustered at low and high elevations in the dry season. Additionally, the responses of fish diversity and community structure to environmental variables were not synchronous.ConclusionsAt the basin scale, environmental filtering was prevalent in shaping fish phylogenetic structure, whereas stochasticity was likely more important for functional structure. Moreover, the ecological mechanisms shaping individual fish communities switched from limiting similarity to environmental filtering as elevation increased, and the underlying forces at two ends of the elevational gradient became more prominent in the dry season.

“…This could suggest that phylogenetic diversity is more reflective of changes in trait space of traits we did not measure, such as those related to phenology (Flynn et al 2011, Galland et al 2019). Thus, using phylogenetic diversity and functional richness can provide a more complete picture of community variation through space and time, despite not being proxies for one another (Pavoine and Bonsall 2011, Sobral and Cianciaruso 2016, Jia et al 2021).…”

“…While functional and phylogenetic diversity indices provide more information on community diversity than taxonomic diversity alone, they are not independent (Jia et al 2021). Our results suggest that variations in FR and PD are due to gains and losses of unique species, particularly with respect to life history and abiotic niche strategies.…”

How communities are structured is a fundamental ecological question. Community structure, while constrained by the regional species pool, may be altered by changes in climate and other environmental stressors. Changes in patterns of functional and phylogenetic dispersion over time can illuminate the temporal dynamics of the processes structuring communities. We quantified temporal changes in taxonomic, functional and phylogenetic diversity of stream fish assemblages in the southern plains of the U.S. across four decades to assess how climatic change has influenced community patterns. We also explored how the use of three different functional trait categories (life history, environmental tolerance and trophic level) and all traits combined affected the response of functional diversity to environmental drivers. We found, for all diversity indices, that assemblages with low historical richness had high contemporary diversity, while assemblages with high historical richness had low contemporary diversity. Functional richness based on life history traits, trophic traits, and all traits combined decreased in diversity over time, while functional richness based on environmental tolerance traits showed the opposite pattern. Phylogenetic dispersion of both over‐ and under‐dispersed communities shifted toward randomness. Changes in fish diversity patterns were influenced by changes in temperature over time, though impacts were metric dependent. Overall, we found that while community structure has changed, specific changes were more strongly predicted by the historical richness of the community than by regional climate change.

“…Due to the lack of a true phylogenetic tree involving all the macroinvertebrate taxa in Tibet, we employed taxonomic distance based on path lengths in the Linnean taxonomic tree as a surrogate for true phylogeny (Cardoso et al, 2015). Since the positions of species in a taxonomic tree usually mirror their positions of the topological structure in a phylogenetic tree, this method is regarded as a robust proxy, and has been widely used in phylogenetic diversity studies (Jia et al, 2021; Liu et al, 2021; Teichert et al, 2018).…”

Aim: Disentangling how stochastic and deterministic processes contribute to variation in beta diversity is a common goal for ecologists and biogeographers. However, such studies are scarce in alpine streams, especially when different diversity facets are considered. Here, we combined different approaches to examine the drivers of taxonomic, phylogenetic and functional beta diversities, and discussed how our results can inform community assembly and biodiversity conservation in Tibetan streams.Location: Tibet plateau. Taxon: Macroinvertebrates. Methods:We first partitioned multiple facets of beta diversity (Btotal) into species replacement (Brepl) and richness difference (Brich) as well as local (LCBD) or species (SCBD) contributions. Then, we applied ordination methods to examine the relative importance of local, climatic and spatial factors on Btotal, Brepl and Brich, respectively. We explored community assembly rules using null models based on trait and phylogeny structure.Results: Btotal displayed high values and was primarily driven by Brepl. Local, climatic and spatial factors were poor predictors of the different facets of beta diversity. Null models showed that the diversity metrics did not differ from those of null expectations, suggesting that most individual streams might be occupied by species that were merely random draws from the functional or phylogenetic pools available in this region. Partitioning beta diversity into LCBD and SCBD implied that the upper canyon streams were more unique than those at lower elevations and can be valuable for biodiversity conservation.Main Conclusions: Analysing multiple facets of beta diversity provide important insights into community assembly that cannot be acquired by focusing on taxonomic diversity only. Using a multi-faceted approach involving species, phylogenetic and trait data, our study not only sheds light on the assembly mechanisms of macroinvertebrate communities in alpine streams, but also bring inspirations for biodiversity conservation in the 'World's Third Pole' that is highly sensitive to global change.
