Description
Yasmin Rodrigues de Souza and co-authors track tiny drifting animals called ciliates in a Brazilian river floodplain over fourteen years, in a 2026 study. They compared two stretches of the Upper Paraná River: one changed by a dam, and one protected and left natural. From 2010 to 2024 they watched species counts, numbers, and how the mix of species shifted over time.
Both stretches lost species and density, but the losses ran deeper in the dammed stretch. That stretch also showed stronger turnover in its species mix and more locally unique samples. Chemical and physical factors in the water drove most of the change in both places. The authors warn that legal protection alone does not keep a floodplain healthy; natural flood pulses must keep flowing.
