Scientists use satellite to monitor pink dolphins
Swimming with the piranhas and boa constrictors underneath the outer layer of the Amazon River in Bolivia is an uncommon animal categories: pink, freshwater dolphins.
These creatures, privately known as "bufeos," are a marker species that researchers say embody the general soundness of the Amazon - - If they are progressing nicely, then the stream is as well.
The Amazon waterway dolphin or Pink River Dolphin, is a freshwater stream dolphin endemic to the Amazon, displayed here February 2010.

"Nightline" went in the background of an experimental run program supported by the World Wildlife Fund (WWF) in which a gathering of nearby anglers and researchers track and study the propensities for the well evolved creature, which is declining in numbers. The program is essential for a bigger exertion by the WWF to label fifteen pink dolphins across Bolivia, Colombia and Brazil to concentrate on their movement, wellbeing and hereditary qualities.
Worldwide help to preserve a neighborhood animal categories
Nearby fishermen would dash along the waterway to find dolphins and set up their nets to safely capture them. After the dolphins were captured and returned to shore, the scientists went into action.Working in a sequential system of building exercises, they organized the dolphin's rapid physique.In the shade of the tent, the group gave the dolphin some water to calm its fear. The clinical mission was led by veterinarian Carla Sanchez to continuously monitor the dolphin's vital signs.neighborhood fishermen bring a pink dolphin ashore for researchers to track and study.Time was of the essence in trying to be successful. Over time, analysts estimated, evaluated the well-developed creature and, surprisingly, really looked at its teeth. They also looked for nearby sedatives to numb the tail, then cut a small amount of tissue to test for mercury, toxins, and the dolphin's general well-
being.Paul van Damme, researcher and director of the Bolivian NGO FaunAgua, WWF field worker for this mission, agrees that monitoring the pink dolphin should be a global enterprise.Researcher Paul van Damme led a dolphin tagging campaign in Bolivia to study and ration pink dolphin declines.Researchers don't know what gives these freshwater dolphins their pale pink color, but part of the theory involves their diet and behavior, as well as water quality and openness to daylight. What is certain is that dolphins turn pink as they age.Deforestation is one of the greatest intimidations of humans, leaving this species powerless in the face of extinction.
In the case of dolphins, the runoff of detritus caused by deforestation prevents them from swimming freely.In 2010, 26 pink dolphins had to be rescued when they were stranded in a shallow creek.“It could be thought of as a cork in the wine, so the cork blocked the flow and the dolphins were trapped in the fairway. The fewer trees, the more mud went in,” said Jordi Surkin, head of the Amazon Coordination Unit at WWF.“The enormous problems faced by pink dolphins in Bolivia and throughout the Amazon are fundamentally similar. There are dams blocking the waterways.There is mercury contamination that usually comes from limited mining," he said.Another threat to vertebrates is the evolution of dolphin meat as a fish trap. While this threat has been mitigated in Bolivia, where pink dolphins are legally protected, the species is most endangered in Brazil and Colombia."Nightline" joined van Damme's group to review the state of the art in tagging dolphin satellites - the other five were tagged by them.
"You have to be aware of how far they travel, how far the young travel in the creek, looking for wives, looking for families, looking for food," said van Damme.scientists are actually studying the heartbeat of a pink dolphin in Bolivia.During a heavy storm, the group continued to organize. The fishermen stubbornly clung to the dolphin in their nets and soon the standard of the group began.When they checked her pulse, the researchers found that the pink dolphin was female but not pregnant. She was named "Ponchita" and would be the main runner-up.
The group recently caught and brought back a pregnant dolphin without tagging it so as not to disturb it.During the work, the people in the group did not use many words, speaking almost softly, with the ultimate goal of silencing the dolphin as expected.Upon completion of the test, Ponchita was injected with a sedative and, using an electric drill typically found in carports, drilled a hole in the back steps for the earring. Because dolphin balance is usually a ligament, the researchers assured Nightline that the deterioration was insignificant.A group of 35 people entered the satellite spot of a pink dolphin in the Amazon, Bolivia.However, the pursuer was off balance with the dolphin, so they took the second opportunity to switch holes.The group shared praise and high fives.
With every one of their labels effectively sent into the Amazon, the group stopped to compliment one another and take a gathering photograph. The labeling piece of the work was done yet there would ultimately be four to a half year of information from the satellite labels coming in to their PCs to examine.
He said this data will be an underlying advance in seeing how to help the pink waterway dolphins. Appreciate it.
