Background Freshwater fish populations are facing multiple stressors, including climate change, species invasion, and anthropogenic interference. Temporal studies of fish functional diversity and community assembly rules based on trait-environment relationships provide insights into fish community structure in riverine ecosystems. Methods Fish samples were collected in 2015 in the Min River, the largest freshwater riverine system in Southeastern China. Fish functional diversity was compared with the background investigation in 1979. Changes in functional richness, functional evenness, functional divergence, and functional beta diversity were analyzed. Relationships between functional diversity and environmental factors were modeled by random forest regression. Correlations between fish functional traits and environmental factors were detected by fourth-corner combined with RLQ analysis. Results Functional richness was significantly reduced in 2015 compared with 1979. Functional beta diversity in 2015 was significantly higher than that in 1979, with functional nestedness being the driving component. Reduction of functional richness and domination of functional nestedness is associated with species loss. Trait convergence was the dominant mechanism driving the temporal changes of functional diversity. Precipitation, temperature, species invasion, and human population were the most significant factors driving fish functional diversity. Higher precipitation, higher temperature, and presence of invasive species were significantly associated with higher swimming factor and higher relative eye diameter, while the opposite environmental conditions were significantly associated with higher pectoral fin length and eurytopic water flow preference. Conclusions Environmental filtering is the dominant temporal assembly mechanism shaping fish community structure. This work contributes to the understanding of temporal freshwater fish community assembly and the associations between fish functional structure and local environmental conditions, which will be informative for future freshwater fish conservation.

Regional Species Pool

There is perhaps no more fundamental question in ecology than what determines the number and kinds of species found in a community and their relative abundances. This chapter lays out a powerful approach to answering this question, based on the concepts of a regional species pool and environmental filters. The species pool is the set of species that could potentially colonize a local site or community. Of these potential colonists, some species are limited in their ability to disperse to site, some are limited by their ability to survive the abiotic environment, and some are limited by their interactions with other species. These “filters” act individually or in concert, and the functional traits of species determine their success in passing through these filters to colonize a local site. There is growing empirical evidence that both abiotic and biotic processes select for specific functional traits. Focusing on the functional traits of species may lead to rules of community assembly that are general and help unify a variety of more specific theories.

The World

In the Amazon basin it is distributed the greatest diversity of freshwater fish in the world, but presents less than half of the species described and/or with little knowledge about its biology and distribution. This work presents the composition of the ichthyofauna Igarapé Praquiquara, located in the municipality of Castanhal, belonging to the Northeast Atlantic Hydrographic Region, Brazil, through collections were conducted in the years 2014 and 2015. A total number of 1,073 fish were sampled, belonging to five orders, 16 families, 35 genus and 42 species. Characiformes and Perciformes were the most predominant orders, Cichlidae and Characidae were the most abundant families, and Bryconops giacopinni, Cyphocharax gouldingi, Astyanax sp., Geophagus proximus and Satanoperca jurupari the most abundant species. Igarapé Praquiquara is composed of species with moderate commercial interest for commercial aquariums, with the presence of species cultivated in other regions. A structural analysis of the igarapé fish community is recommended in order to identify which factors are responsible for the composition of the ichthyofauna present, as well as the influence of the dam on the dispersion, distribution and reproduction of species.
