In December, researchers gathered extensive data on a population of Amazon river dolphins in the Amanã Sustainable Development Reserve in the Brazilian state of Amazonas.
They fitted some of the dolphins with radio transmitters to help map their preferred zones and identify priority regions for species protection.

Hydroelectric dams, fishing, and contamination from mining pose the greatest threats to the species across its range.
