N1 - Funding Information:
Data analyses and manuscript writing for this paper were based on large database generated from a coordinated regional set of mesocosm experiments that were that were funded and executed by a broad collaborative network of scientists across North America and Europe in 2018 (initiated at Global Lake Ecological Observatory Network [GLEON] meeting 2017). The collaborations were solidified by a Canadian Institute for Ecology and Evolution (CIEE)‐funded workshop in 2019 (SEA and WDH) and a Groupe de Recherche Interuniversitaire en Limnologie du Québec (GRIL)‐funded workshop in 2020 (AMD and BEB). Funding for experiments was provided by individual research grants awarded by the Natural Sciences and Engineering Research Council (NSERC) Discovery Grant program (AMD, BEB, DKG, SEA, SJM) and the National Science Foundation (CFS award 1354063, JBS award 1457737); the authors also acknowledge NSERC‐funded contributions from Gregor Fussmann. The Swedish Research Council (grant #2017‐00635) funded the SITES AquaNet mesocosm facility which is part of the Swedish Infrastructure for Ecosystem Science (SITES). The authors are also grateful for various forms of support from the Ontario Ministry of Environment, Conservation, and Parks (Best‐in‐Science; SEA), Queen's University Biological Station (SEA), Dorset Environmental Science Centre (SEA, JR), Ohio Wesleyan Summer Science Research Program (AD), Jefferson Project at Lake George (WDH, RAR, MSS, ATG; a collaboration of the Rensselaer Polytechnic Institute, IBM Research, and The FUND for Lake George), the University of Toledo (WDH), the European Commission LIFE program via the LIFE DEMINE project (LP), the Swedish Research Council (GAW, HL), the Swedish Research Council Vetenskapsraet (2017‐06421; PUC), Linnaeus University (SH), Umeå University (LL), and Uppsala University (SL). Support for researchers was also provided by NSERC (MPH, EH, LA, ST), a Craigie Fellowship (DAG), Walter and Andrèe de Nottbeck Foundation (NG), the Serra Húnter Programme (MCA), the Programme Beatriu de Pinós (Secretary of Universities and Research, Government of Catalonia) and the Horizon Programme of Research and Innovation of the European Union under the Marie Skłodowska‐Curie Grant Agreement No. 801370 (LP).

N2 - The salinization of freshwaters is a global threat to aquatic biodiversity. We quantified variation in chloride (Cl−) tolerance of 19 freshwater zooplankton species in four countries to answer three questions: (1) How much variation in Cl− tolerance is present among populations? (2) What factors predict intraspecific variation in Cl− tolerance? (3) Must we account for intraspecific variation to accurately predict community Cl− tolerance? We conducted field mesocosm experiments at 16 sites and compiled acute LC50s from published laboratory studies. We found high variation in LC50s for Cl− tolerance in multiple species, which, in the experiment, was only explained by zooplankton community composition. Variation in species-LC50 was high enough that at 45% of lakes, community response was not predictable based on species tolerances measured at other sites. This suggests that water quality guidelines should be based on multiple populations and communities to account for large intraspecific variation in Cl− tolerance.
