We found that including nonlinearity improved 5/6 models while the inclusion of interactions improved 6/6 models! A huge thanks to @penkmar and @jaypiggott for helping with this project!

Delighted to share our new papers (led by Dr. Julia Hunn, not on Twitter) exploring the interactive effects of CO2, heatwaves, flow variability and sedimentation on river ecosystems (doi.org/10.1111/gcb.17336 and doi.org/10.1016/j.scitotenv.…)
