Scientists have found out the impact of the Tunguska meteorite and climate change on aquatic ecosystems

Scientists from the Siberian Federal University and the Institute of Biophysics of the Siberian Branch of the Russian Academy of Sciences studied how the explosion of the Tunguska meteorite affected the ecosystem of reservoirs near the epicenter of the event. They also studied the impact of climate change on lake biodiversity.

It is special on the peninsula, but the methods of studying this territory will help to see future changes in other regions.

The study was conducted on the inaccessible lake Zapovednoye in the Krasnoyarsk Territory. It is located on the border of permafrost, which makes its ecosystem particularly sensitive to climate change.

"The technology is based on techniques developed by Russian scientists. They are based on the analysis of sediments that accumulate at the bottom of lakes. Bioindicators are the remains of ancient flora and fauna. For example, plant pollen particles, the remains of planktonic organisms that existed in the past," Denis Rogozin, professor of the Siberian Federal University Department of Biophysics, Deputy Director for Science and a leading researcher at the IBF SB RAS, Doctor of Biological Sciences, told Izvestia.

He explained that in the course of scientific work, scientists have reconstructed the history of climate in the region over the past 2.2 thousand years.

At the same time, experts found traces of soil erosion in the samples due to the massive fall of trees, which occurred due to the so-called Tunguska event - an atmospheric explosion caused by a meteorite fall in 1908. This changed the balance of the ecosystem, and it took about 50 years to restore it.
