Data source and code are of course freely available. And hopefully a useful source for future predictive models in aquatic stress ecology.

We observed consistent relation with salinity, oxygen depletion, and fine sediment accumulation, while the relation with nutrient enrichment and warming varied among groups. The results allow us, amongst others, to predict how species richness changes with increasing stressors intensity (Fig. 3):

The figure (1a) shows the probability distribution on how species number of the different organism groups are associated with increasing stress intensity. Invertebrates are generally most sensitive and species number is negatively associated to six of the stressors.

We extracted data on 1,332 stressor–response relationships from literature and ran Generalised Linear Mixed Models for each dataset individually. With the resulting estimates (e.g. regression coefficients) we performed a Bayesian meta-analysis.
In short, these are the results:

Diverging fish biodiversity trends in cold and warm rivers and streams - Nature
In the past three decades, fish abundance, richness and uniqueness have diverged across cold and warm streams, and the effects on native fish communities of stream warming and increases in introduced fishes have magnified each other.
