How Rivers Shape Genetic Diversity: Lessons from Riparian Plants

Riparian zones—the transitional ecosystems lining rivers and streams—play a vital role in maintaining biodiversity, stabilizing soils, filtering pollutants, and regulating microclimates [2,3]. Yet, these ecologically valuable corridors face increasing threats from dam construction, land-use change, and climate-driven hydrological shifts. A new global-scale meta-analysis by Surmacz et al. [4] sheds light on how such pressures influence the genetic diversity of riparian plants and the factors that shape these spatial patterns.
