What is it about?
Diaptomid copepods are microscopic crustaceans that play a crucial role in freshwater food webs across South America. This study models how climate change is expected to affect the richness and distribution of these tiny organisms in the La Plata Basin — one of the largest river systems in the world. Our projections show significant shifts in species richness under future climate scenarios, with some areas facing potential losses. These findings offer important insights for freshwater conservation planning in the face of a changing climate.

Why is it important?
Copepods are often overlooked in conservation discussions despite being key links in aquatic food chains. This study is among the first to forecast climate-driven changes in diaptomid copepod diversity across the La Plata Basin, providing a valuable tool for biodiversity conservation planning. The results highlight specific regions where management action will be most urgently needed as temperatures and precipitation patterns change.
Perspectives
This research highlights how even the smallest organisms can be profoundly affected by climate change. We hope this work draws attention to the often-invisible freshwater biodiversity of South America's great river basins and encourages their inclusion in regional conservation strategies.
