The causes of mass death of seals in the Caspian sea by Russian scientists find. Over the past few days on the coast threw hundreds of carcasses. Presumably, the animals kills the virus or poisonous run-off. The extinction of this species will lead to failure in the ecosystem of the sea.
Group of experts on marine mammals from Moscow, Novosibirsk and Makhachkala for 20 km of travel along the coast found 146 dead seals. The numbers, according to experienced professionals, who are working in Antarctica, disappointing.
A similar pattern in almost all their habitats. Makhachkala youth, those who under 30 remembers a time when Antarctica seals met just a few dozen metres from the shore. But then, whether from the massive emissions of sewage in the sea, whether from a growing human presence, the animals moved in a desert place. About them was not heard until recently. Until something began to mow down the population. Something is still not clear even to scientists.
History already has many examples of the rapid decline of the Caspian seal. In the twentieth century, they are killed for their fat and skins. The number of individuals then a million have fallen by half. But craft already in the past, but to die, the seals continue. Versions of the environmentalists a few. Obviously it is only that the cause of death is clearly not hunger. A more likely version experts believe the virus. Therefore, samples for assays were taken even with the birds. On the subject of any disease.
There are precedents: in 2000, 10 thousand seals died from canine distemper. Whatever the test results, environmentalists say about the seriousness of the problem. Research the causes of mass deaths of Caspian seals will continue. Connect to already intend experts from the Netherlands. Interest is expected. Because the Caspian sea is home to many different animals, but the seal, this is his view, can only be found there. Seal the top of the food chain of Caspian sea.
