Scientists from the IEE RAS, SFU, Krasnoyarsk Scientific Center of the Siberian Branch of the RAS, and the Privolzhskaya Lesostep Nature Reserve investigated the role of the tailless amphibian Pallas' spadefoot in the transfer of organic matter from small water bodies to land.

Cytogenetics belongs to the field of genetics, to the emergence and rapid spread of which the Russian school of chromosome researchers made a special contribution.

Russian biologists, together with foreign colleagues, have deciphered the genome of microscopic daphnia crustaceans living on the Arabian Peninsula.

The published study is the first deep generalization on the most dangerous invasive species in Russia, performed using ecological modeling methods and geoinformation technologies, which has no analogues both in Russia and abroad.

Using the Paleoenvironmental Distribution Modeling (SDM) method, we reconstructed the range history of the largest member of the Cricetinae subfamily, the common hamster (Cricetus cricetus).

At the beginning of this year, the peer-reviewed scientific journal Animals published an article “Is the Lesser Khingan suitable for the restoration of the Amur tiger group? Perspectives in terms of habitats and food supply”.

The black soldier fly Hermetia illucens (Diptera: Stratiomyidae) is widely used in the modern world for the production of a quality food product containing from 30% to 47% protein and 10–35% fat, which is used both in raising farm animals and in food production for humans.
