“…Studying the contribution of β ‐diversity from different facets is crucial to analyzing the causality of potential biodiversity processes (Gianuca et al, 2017 ; Taylor, 2010 ; Villeger et al, 2013 ). The results showed that functional β ‐diversity was higher than taxonomic and phylogenetic β ‐diversity (0.686 vs. 0.612 vs. 0.490), this was not our expectation but is consistent with recent findings on fish (Araujo et al, 2019 ; Jia et al, 2020 ). High functional β ‐diversity (Figure 2 ) may have the following two reasons: (i) low abundance of Hun‐Tai river fish species compared with algae and macrobenthos (Qu et al, 2019 ; Wu et al, 2021 ), species with substantial overlap between combinations (e.g., certain common species occur multiple times in fish assemblages); (ii) fish of the same genus may have different functional traits.…”

“…In addition, we found that turnover dominates fish taxonomic and phylogenetic β ‐diversity, suggesting the predominance of species replacement over species loss (Araujo et al, 2019 ). Similar patterns have been observed in previous studies on fish (Liu & Wang, 2018 ; Lopez‐Delgado et al, 2020 ).…”

“…For example, two fishes of the same genus ( Etheostoma flabellare and E. olmstedi ) have interspecific differences in performance (Carlisle et al, 2008 ). Compared with taxonomic and phylogenetic facets, higher functional β ‐diversity shows that different species often play distinct functions in spatial environment combination (Araujo et al, 2019 ).…”

“…Identifying the mechanisms that drive local environmental and intercommunity change is at the heart of community ecology (Baselga, 2010 ; Padial et al, 2014 ; Perez Rocha et al, 2018 ). Several previous studies have pointed out that local environmental ( Local ) variables are the main structural factors influencing fish communities (Araujo et al, 2019 ; Leprieur et al, 2012 ; Lopez‐Delgado et al, 2020 ). But, in recent years, more scholars have found that river biodiversity patterns are driven by a variety of abiotic factors (Goncalves et al, 2020 ; Grenouillet et al, 2008 ; Vardakas et al, 2020 ).…”

The primary objective of this study was to determine the relative roles of local environmental ( Local ), geo‐climatic ( Geo ), and spatial ( Spatial ) factors to taxonomic, functional, and phylogenetic β ‐diversity of stream fish in a large basin in Northeast China. We quantified the current biodiversity patterns of fish communities in the Hun‐Tai River using β ‐diversity. We assessed (i) corresponding contributions of turnover and nestedness within the taxonomic, functional, and phylogenetic β ‐diversity of fishes; (ii) correlations among β ‐diversity facets (i.e., taxonomic, functional, and phylogenetic facets); (iii) relative contributions of Local , Geo , and Spatial factors to β ‐diversity. We collected fish communities from 171 sampling sites. Mantel tests were used to examine the correlation of three facets of β ‐diversity and their components (i.e., total, nestedness, and turnover). Distance‐based redundancy analysis and variation partitioning assess the relative contributions of Local , Geo , and Spatial factors to β ‐diversity. We found that turnover is the main driving mechanism for β ‐diversity in fish. Among the facets of β ‐diversity, taxonomic and phylogenetic facets have strong ecological information association. Spatial factors have a general contribution to various facets of β ‐diversity and its components. From aspects of fish β ‐diversity conservation, connectivity and habitat heterogeneity need to be maintained in the entire aquatic environment. In addition, protecting taxonomic β ‐diversity is helpful for maintaining phylogenetic β ‐diversity.

Ecological functions are linked to the condition and stability of coastal ecosystems. Quantifying how human disturbance and seascape context influence biodiversity and how different forms of diversity (i.e. species richness and functional diversity) influence ecological functioning is important in managing coastal ecosystems. We measured if the rates of carrion consumption by fish and crustaceans were influenced by scavenger richness and functional diversity or the abundance of key scavenger species, and which environmental factors shaped carrion consumption in surf zones at 20 beaches in eastern Queensland, Australia. Carrion consumption was positively correlated with scavenger richness, functional diversity, and the abundance of two species: weeping toadfish (Torquigener pleurogramma) and ornate wobbegong (Orectolobus ornatus). Carrion consumption was highest at sites that were near rocky headlands (<1 km) and shark control programme equipment (<1 km) and was also characterized by functional complementarity as weeping toadfish consumed more carrion at sites with a smaller area of reef nearby (<0.1 km2), whilst ornate wobbegong consumed more carrion at sites with a larger area of reef nearby (>0.3 km2). We highlight the importance of scavenger richness and functional diversity in shaping carrion consumption in surf zones, particularly when the species performing the function do this in spatially distinct areas.
