{ "abstract": "Assessments of broad-scale biodiversity change commonly aggregate communities that differ in their initial impacts and their total degree of change (differing \"impact trajectories\"). Biodiversity responses may depend on the impact trajectory of a given community; thus, not controlling for these differences could produce a misleading mixture of trends even if all communities degraded or recovered. To evaluate this dependency, we related biodiversity trends for 4062 river invertebrate time series (1971 to 2024) from 23 European countries to impact trajectories for each community, quantified through comparison to least-impacted references. Trends were typically stronger and more consistent in initially more impacted communities that also exhibited more extreme total change. However, responses were weaker when initial impacts were lower and highly inconsistent with lesser total change. Our results show that biodiversity trends should be compared among communities with similar impacts, determined relative to appropriate references. Improving trend comparability is essential to accurately determine how biodiversity generally responds to anthropogenic impacts and conservation actions.", "abstract_shown": true, "affiliations": [ "Senckenberg–Leibniz Institution for Biodiversity and Earth System Research, Senckenberg Research Institute and Natural History Museum Frankfurt, Gelnhausen 63571, Germany.", "Marine and Freshwater Solutions, Finnish Environment Institute, Oulu 90014, Finland.", "State Scientific Research Institute Nature Research Centre, Vilnius 08412, Lithuania.", "Czech Hydrometeorological Institute, Praha 143 00, Czech Republic.", "Environmental Protection Agency, Dublin D14 YR62, Ireland.", "SHE2 group (Surface Hydrology, Ecology and Erosion), FEHM-Lab, Institute of Environmental Assessment and Water Research, IDAEA, CSIC, Barcelona, Catalonia 08034, Spain.", "IFREMER–DYNECO/LEBCO, Centre de Bretagne, Plouzané, France.", "INRAE, UMR Agroecologie, Centre de Dijon, Dijon, Cedex 21065, France.", "INRAE, UR RiverLy, Centre de Lyon-Villeurbanne, Villeurbanne, Cedex, France.", "Department of Animal Sciences and Aquatic Ecology, Ghent University, Gent 9000, Belgium.", "IHCantabria—Instituto de Hidráulica Ambiental de la Universidad de Cantabria, C/Isabel Torres 15, Santander 39011, Spain.", "Ecology and Genetics Research Unit, University of Oulu, Oulu 90014, Finland.", "Institute of Marine Biological Resources and Inland Waters, Hellenic Centre for Marine Research, Anavyssos 19013, Greece.", "Department of Plant Biology and Ecology, University of the Basque Country (UPV/EHU), Leioa, Bilbao 48940, Spain.", "Norwegian Institute for Water Research (NIVA), Oslo 0579, Norway.", "Faculty of Biology, University of Duisburg-Essen, Essen 45141, Germany.", "Research Center One Health Ruhr, University Alliance Ruhr, Essen 45141, Germany.", "Department of Botany and Zoology, Faculty of Science, Masaryk University, Brno 611 37, Czech Republic.", "T.
