Passive acoustic monitoring of river dolphin (Inia geoffrensis and Sotalia fluviatilis) presence:

Latin American Journal of Aquatic Mammals, 2021
All river dolphin species are in decline as a direct result of intensified anthropogenic activity along river systems. In South America, the size and geographical complexity of their range pose a challenge to status assessment. Passive acoustic monitoring offers a cost-effective, scalable, and readily standardized method for determining species ...

Breaking down silos: Conservation areas for Amazonian flagship terrestrial and freshwater species

Conservation Science and Practice, Volume 7, Issue 9, September 2025.
This study shows that 17% of the Amazon River Basin is covered by areas of high jaguar density and freshwater migratory species richness, 83% of which are found in Brazil and Peru. A third of these areas are located outside of formal protected areas or Indigenous territories.
