Human disturbance and long-term changes in fish taxonomic, functional and phylogenetic diversity in the Yellow River, China

Deep reefs are not refugium for shallow‐water fish communities in the southwestern Atlantic

“…Because human stressors are more intense in shallow reefs, and only a small number of disturbance-tolerant lineages may take advantage of the new conditions in the Anthropocene (Jia et al, 2020;Ribeiro et al, 2016), we expected more phylogenetic homogenization among shallow reefs than among deep reefs. However, this did not happen, suggesting that deep reefs do not count with more evolutionary diversity to couple with ongoing and future changes.…”

Preface: aquatic homogenocene—understanding the era of biological re-shuffling in aquatic ecosystems

“…Past investigations of BH have largely focused on reconstructed species pools from published lists of native, extinct, and/or nonnative species, thus limiting comparisons to be made between some ''historical'' baseline and the present day (Rosenblad & Sax, 2017). In this special issue, Jia et al (2020) used data from a 50-year period; Brito et al 2020and Lindholm et al (2020) examined data over a 70-year period; Kirk et al (2020) leveraged historical data starting in the 1890's; and Peoples et al (2020) used an estimation of original fish fauna in North America before European colonization. One paper examined patterns of community composition before and after major dam construction , and other 5 papers used data from c. 10-20 years, coinciding with popularization of longterm ecological programs and standard ecological assessments.…”

“…This special issue helped to fill this knowledge gap. Ten of the 13 papers addressed some aspect of functional diversity, and a single paper simultaneously examined taxonomic, functional, and phylogenetic diversity (Jia et al, 2020). We believe that further investigation of the phylogenetic aspects of BH is warranted.…”

“…In the sole paper addressing simultaneously taxonomic, functional and phylogenetic facets of biodiversity, Jia et al (2020) suggested that the homogenization of functional and phylogenetic components were strongest for the ichthyofauna of Yellow River, China. They demonstrated that despite increases in alpha diversity, beta diversity decreased over time (in agreement with Peoples et al, 2020), which reinforces that biodiversity should be used cautiously as an indicator of environmental wealth (Vellend, 2020).…”

Effects of land use on the β‐diversity of fish assemblages in subtropical headwater streams, China

“…Taxonomic and functional β‐diversities compared to taxonomic and functional α‐diversities can not only quantify the variation magnitude of species and functional composition between assemblages (Whittaker, 1960) but can also predict the trends in the variation of both them between assemblages after anthropogenic disturbances (e.g. land use, deforestation and dam construction; Jia et al, 2020; Johnson & Angeler, 2014; Zhang et al, 2019). One such trend would be taxonomic and functional homogenisation, which means taxonomic and functional beta diversity decline in other words (Marchetti et al, 2006; Villéger et al, 2014).…”
