Brazil’s non-native mollusc tally has jumped 215% in 15 years, and scientists say 82 species now need closer watch because some already damage farms, rivers and power plants

Brazil’s waterways are facing an ecological crisis as non-native mollusc species have surged by over 200% in just 15 years. International trade and shipping have introduced these adaptable invaders, which now threaten infrastructure like power plants and agricultural production. Experts warn that current biosecurity measures are insufficient, necessitating stronger early detection and stricter regulations to combat this escalating biological takeover.
