In the bunker during the cold war found an isolated colony of ants losers


In the Polish nuclear bunker, built during the so-called cold war near the border with Germany, scientists have discovered a very unusual colony of ants. Conditions in the bunker not too suitable for insect life and still less for their reproduction, but to leave the ants can’t. However, the colony persists and even grows. In the end, the researchers were able to unravel the secret of her success is quite controversial.

The researchers found, in an underground colony no sunlight penetrates, the temperature almost never rises even to 10 degrees Celsius, and the food is virtually nonexistent. The main feature of the colony is that the ants falling into its territory through the ventilation shaft of the bunker, forced to remain in it forever. And, although established in it the conditions were unsuitable for breeding, this does not prevent insects, doomed to live in the bunker, continue to finish inside the anthill. While their population continues to grow ants who are not lucky enough to fall into the mine.

Previously an underground bunker, built under the agreement between the Polish people’s Republic and the USSR, was used for storage of tactical nuclear weapons. The weapons were removed in 1992. After that, the facility of the penetrated animals only ants, mites and small bats. The excrement of the latter, in all probability, represent the only power source of the ants, allowing them to somehow survive underground.

For the first time, an unusual population of ants, the scientists were able to discover in 2013, and two years later, experts noticed that it is not only not disappeared, but expanded. Then scientists dug up the anthill and saw again that its inhabitants do not reproduce. In 2016, the researchers once again concluded that the colony is “booming” and noticed that the damage of the nest restored. A large number of dead rodents, according to experts, suggests that the ants live in the bunker for a very long time. Its current “population”, according to estimates of biologists, can reach a million individuals.
