In response to final yr’s devastating drought within the Amazon, which led to the loss of life of over 200 river dolphins, a staff comprising biologists, veterinarians, and native fishermen has launched into an important mission. Coordinated by the Mamirauá Institute for Sustainable Improvement, this venture goals to evaluate and safeguard the well being of the endangered Amazon river dolphins, recognized for his or her distinct pink hue.
This examine occurred in Lake Tefé, a physique of water fed by a tributary of the Amazon River. The staff carried out a collection of delicate operations to seize as much as 20 dolphins.

Final yr’s drought—essentially the most extended in recorded historical past—brought about river ranges to drop drastically, elevating water temperatures considerably. Such situations should not solely inhospitable however deadly, as evidenced by the mass mortality of dolphins and 1000’s of fish, which suffered because of depleted oxygen ranges within the water.
The initiative additionally included the set up of microchips within the dolphins, facilitating future monitoring and identification. Whereas satellite tv for pc tags, which observe the dolphins’ conduct and environmental situations, weren’t but hooked up, they’re a part of the broader effort to know and mitigate the impacts of Local weather change on this susceptible species.
By gathering information on the well being of the dolphins at crucial instances—when water ranges fall and temperatures rise—the researchers intention to pinpoint the exact causes of the deaths. Whether or not these are because of elevated temperatures, toxins, or pollution, figuring out the triggers is essential for creating well timed and efficient Conservation methods.
This examine not solely highlights the direct results of local weather change on wildlife but additionally underscores the significance of proactive environmental stewardship. With the collaboration of worldwide our bodies just like the Nationwide Marine Mammal Basis of California, the venture exemplifies a worldwide dedication to preserving one of many Amazon’s most iconic species amidst escalating local weather challenges.
