AB  - A recent global meta-analysis reported a decrease in terrestrial but increase in
freshwater insect abundance and biomass (van Klink et al., Science 368, p.
417). The authors suggested that water quality has been improving, thereby
challenging recent reports documenting drastic global declines in freshwater
biodiversity. We raise two major concerns with the meta-analysis and suggest
that these account for the discrepancy with the declines reported elsewhere.
First, total abundance and bioma...
