Extended Data Fig. 10: Exposure of fish species to hypoxia.
From: Climate change drives low dissolved oxygen and increased hypoxia rates in rivers worldwide
(a) Freshwater fish species richness (SR) distribution (data from ref. 18). (b) Average trends in the number of freshwater fish species exposed to hypoxia per decade from 2020 to 2100 based on five Global Climate Models (GCMs) for SSP3-RCP7.0 scenario and using DynQual_Random Forest (percentage change) (c) Time-series of the total number of fish species exposed to hypoxia (DO < 2 mg/l) during 2020-2100 with the ensemble mean (thick line) and uncertainty bounds (±− standard deviation) of the 5 GCMs (DynQual_Random Forest) (d) Time-series of the total number of fish species exposed to hypoxia (DO < 3 mg/l) during 2020-2100 with the ensemble mean (thick line) and uncertainty bounds of the 5 GCMs (±− standard deviation) (DynQual_Random Forest).
