“…This is because the FD needed to maintain numerous ecosystem functions is reduced (Hilt et al., 2017). Our results add to recent empirical evidence from grasslands, temperate lakes and rivers (Freitag et al., 2021; Goto et al., 2021; Zhang et al., 2020), indicating that regime shifts cause a biodiversity decline with negative consequences for important ecosystem functions. From an ecosystem management perspective, the clear state is noticeably more beneficial to human uses as it sustains a better and healthier ecosystem functioning, including higher production of fish biomass.…”

1. Under increasing nutrient loading, shallow lakes may shift from a state of clear water dominated by submerged macrophytes to a turbid state dominated by phytoplankton or a shaded state dominated by floating macrophytes. How such regime shifts mediate the relationship between taxonomic and functional diversities (FD) and lake multifunctionality is poorly understood.2. We employed a detailed database describing a shallow lake over a 12-year period during which the lake has displayed all the three states (clear, turbid and shaded) to investigate how species richness, FD of fish and zooplankton, ecosystem multifunctionality and five individual ecosystem functions (nitrogen and phosphorus concentrations, standing fish biomass, algae production and light availability) differ among states. We also evaluated how the relationship between biodiversity (species richness and FD) and multifunctionality is affected by regime shifts.3. We showed that species richness and the FD of fish and zooplankton were highest during the clear state. The clear state also maintained the highest values of multifunctionality as well as standing fish biomass production, algae biomass and light availability, whereas the turbid and shaded states had higher nutrient concentrations. Functional diversity was the best predictor of multifunctionality. The relationship between FD and multifunctionality was strongly positive

“…Animals with strong mobile ability, such as fish, can rapidly respond to environment variations and experience changes in their community assembly mechanisms over time (Fitzgerald et al, 2017; Fujiwara et al, 2019; Zhang et al, 2020). More species entered the channel during the wet season than the dry season, meaning that emigration or immigration from Poyang Lake was more common during the wet season.…”

“…Thirteen ecological and functional traits of the fish concerning habitat usage, life history and trophic groups were extracted from the existing literature and used to calculate functional diversity (Table S1 and S2). We used the mean value within the same or a similar genus when lack of information for a species (Liu & Wang, 2018; Zhang et al, 2020).…”

Lateral hydrological connectivity (LHC) maintains the high biodiversity and ecosystem functions in the river–floodplain system. We investigated the changes in the taxonomic and functional composition of fish assemblages in the lateral connection channel between the Yangtze River and Poyang Lake, China, during the dry and wet seasons and which factors drive the changes. The results indicated more lake‐residence species and fewer river–lake species in the channel during the wet season than the dry season, leading to significant seasonal differences in taxonomic compositions and trait patterns. Water temperature, water level and fish migration influenced fish assemblage structures in the channel. Water‐level fluctuations that limited food sources and suitable habitats promoted the migration of riverine and lake‐residence fish during both seasons. Water temperature and level also significantly influenced species‐specific migration. Water temperature influenced the spawning migration of river–lake fish during the wet season. Based on these results, we found temporal species‐specific migration dynamics in fish assemblages in the lateral channel that were related to species’ life‐history traits. Therefore, we inferred that the temporal–spatial interaction of the fish community in the river–floodplain system is essentially derived from the evolutionary adaption to the monsoon climate. This process is well studied and predictable, and can be beneficial for managing the river–floodplain systems. The invasion risk of the exotic species, including fish and macroinvertebrates, should be assessed before implementing LHC restoration.

“…Particularmente, en el contexto de la estructura funcional, describimos índices complementarios relacionados con la comunidad objetivo. Además, algunos estudios han incluido más de uno de estos aspectos de comunidades de peces en diferentes ecosistemas, con lo cual han determinado que la diversidad taxonómica y funcional permite superar las limitaciones de la perspectiva clásica, lo cual da resolución a los procesos ecológicos más finos (Villéger et al 2010, Zhang et al 2020.…”

“…Existen 3 diferentes enfoques ecológicos para explorar la estructura de las comunidades de peces de una manera multifacética: el enfoque clásico, que considera los índices ecológicos relacionados con la abundancia y la riqueza de especies; el enfoque taxonómico, que considera las relaciones filogenéticas de las especies que revelan similitudes en el proceso evolutivo (Clarke y Warwick 1999); y el enfoque funcional, have included more than one of these aspects of fish communities in different ecosystems, suggesting that taxonomic and functional diversity allow to overcome the limitations of the classical perspective, providing insights into the finer ecological processes (Villéger et al 2010, Zhang et al 2020.…”

Mangroves are important habitats for fish across latitudinal gradients, but few studies have examined fish community functional diversity in mangroves from arid environments. To address this, we assembled 11 morpho-functional traits and taxonomic diversity for 123 fish species and environmental characteristics from 3 mangrove ecosystems in the Gulf of California, where arid conditions prevail. We compared these arid mangrove fish communities to a semitropical community in an estuarine condition to analyze functionality. Arid mangrove fish communities were similar to each other, but different from semitropical estuarine fish communities (R = 0.951, P = 0.007). Mangrove fish communities had higher trait diversity than the estuarine community, but the estuary had higher redundancy. Taxonomic diversity showed a latitudinal gradient, with the southernmost site in the arid region functioning as a transition site to estuarine communities. Despite the different taxonomic composition, the functional structure remained similar in the fish communities within the arid region and had higher counts of diverse traits than the site with estuarine conditions. High salinity and evaporation deficit in the arid mangroves relaxed habitat filtering pressures relative to the estuarine conditions, where the higher tolerance to salinity changes imposes redundant morphologies. Future studies should focus on seasonal variation of environmental effects on the functional aspects of the fish community.
