Many taxa, par-ticularly in the most species-rich order, Unionida, are declining due to anthropogenic stressors, while a small number of non-native species have become increasingly abundant and widespread, commonly replacing nativebivalve assemblages. To understand how these global changes may impact ecosystems and people, we con-ducted a meta-analysis of existing literature quantifying the ecological functions (= supporting or intermediateecosystem services) and regulating ecosystem services of freshwater bivalves (hereafter “ecosystem services”).Random effects meta-analysis modeling across 447 case studies revealed a positive effect on human health,safety, or comfort of freshwater bivalve ecosystem services overall and specifically, via effects on nativemacrofauna, microorganisms, wastes, and pollutants, and the physico-chemical condition or quantity of sedi-ments. Generally, effects of native species and species within the orders Unionida and Venerida were more sig-nificant and positive than those of other freshwater bivalves. No significant overall effect was found forecosystem services related to zooplankton, algae, invasive species, and the physico-chemical condition of ambi-ent water. Moreover, a significant bias toward publication of positive results existed for studies quantifying eco-system services related to algae. These findings illustrate the global importance of the ecosystem services offreshwater bivalves and highlight the need for large-scale conservation and restoration efforts for their speciesand populations globally, including those of common species. Our findings also question common assumptionsof strong and ubiquitous effects of freshwater bivalves on algae and water condition, cautioning against extrapo-lating observations across systems.
