The ranking scientific journal Acta Biologica Sibirica, which is part of the second quartile of the Scopus database of peer-reviewed scientific literature, published an article by scientists of the ISU Institute of Biology.

The article "Locomotor activity of the Holarctic molluscs Radix auricularia (from Lake Baikal) in various light pollution conditions" is devoted to the study of the effect of artificial lighting on living organisms. Scientists note that this influence exerted by artificial lighting on living organisms in general and hydrobionts in particular is of interest in relation to the problem of light pollution of ecosystems.


Dmitry Karnaukhov, Head of the group of scientists, Junior Researcher at the ISU Biology Research Institute:

"The problem of light pollution has arisen with the increase in the number of sources of street lighting and in some regions of the planet it is already causing significant damage to the environment. The thing is that organisms accustomed to the change of day and night are completely maladapted to "light bulbs" at night, which in turn changes their biological rhythms and leads to the restructuring of biological communities."

In the published work, a team of researchers studied the impact on behavior, or rather the motor activity of a mass and widespread species of snails (radix auricularia or big-ear radix) of artificial lighting with different characteristics. Scientists have found that depending on the characteristics, the effect of artificial lighting on snails is different. So, light, conventionally perceived as "cold" (mostly consisting of the short waves) will lead to an increase in activity unusual for the night time. And "warm" light, on the contrary, reduces the activity of molluscs. Lighting intensity also plays a significant role. Such reactions can potentially lead to different consequences for the population of this species, everything will depend on the size of the water reservoir and on the characteristics of artificial lighting.

Recall that a scientific publication is the main result of a scientist's work, acquainting the scientific community with research, its analysis and conclusions, as well as indicating the priority of the author or group of authors in solving certain scientific problems.
