Mysterious deaths of dolphins linked to climate change

Keith Robb, head of the Marine Mammal Foundation Research Center in Australia, teamed up with

Wildlife Veterinarian Pathologist PadraigDuignan, who worked at the University of Melbourne Veterinary School, and Nahiid Stevens, a veterinary pathologist at Murdoch University who is studying similar dolphin deaths in Western Australia, to try to solve the mysterious deaths of dolphins.

According to scientists, the dolphins died due to the fact that their habitat became desalinated.

More than ten years after the mass deathDolphins In 2007, a group of scientists published in the journal Nature Scientific Reports an article in which the death of dolphins due to freshwater skin disease was associated with climate change.

By the way, fresh water is the reasonfatal skin ulcers not only in dolphins, but also in whales. The new study provides more evidence for freshwater-related deaths in dolphins. In addition, scientists were able to prove that the increase in the number of extreme weather events due to climate change has led to the fact that populations of dolphins enter more fresh water.

Originally biologists, ecologists and pathologistssuspected a bacterial or viral nature of the deadly skin ulcers, but this assumption turned out to be erroneous. The scientists noted that dolphins can tolerate changes in salinity ranges, but the fluctuations caused by climate change were too severe.
