This global meta-analysis of freshwater stressor–response relationships reveals that the biodiversity loss of five riverine organism groups reflects elevated salinity, oxygen depletion and fine sediment accumulation 🧪 www.nature.com/articles/s41...

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

And we can now also align species richness to combinations of stressors (Fig 4):

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:

Led by Wim Kaijser, we published a global analysis on how five different organism groups respond to seven stressor categories. New paper in Nature Ecology & Evolution. www.nature.com/articles/s41....

Does areal transport of pesticides result in relevant exposure? Surprisingly: yes! We found notable concentrations in streams without upstream agriculture. Mean exposure was explained by distance-weighted land use in the surrounding (radius of 50 km). doi.org/10.1016/j.wa...
