New paper out on how stressor numbers influence biodiversity - ecosystem function relationships in freshwater ecosystems. We considered four measures of ecosystem function and found that the positive BEF relationship becomes stronger as the number of stressors increases. OA @ doi.org/10.1111/gcb....
Effects of Biodiversity Loss on Freshwater Ecosystem Functions Increase With the Number of Stressors
The paper reports results of a meta-analysis addressing the effect of multiple stressors on the relationship between biodiversity and four measures of ecosystem function in freshwater ecosystems. We ...

New study on the spatial dimension of multiple stressors. Gemma Burgazzi (iDiv) did a great job in running this mesocosm experiment. Effects of single stressors cascaded along the network, with stronger downstream effects. Thanks to all contributors! @leeselab.bsky.social doi.org/10.1002/ecog...

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.
