Recovering European River Invertebrate Communities Homogenize or Differentiate Depending on Anthropogenic Stress. [PDF]
(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,
