The Russian Far East is a region of mixing of boreal and tropical faunas and a zone of endemism of microscopic crustaceans (Cladocera and Copepoda). The question is of interest: how does the formation of zooplankton communities occur in this border region?

The next (spring) stage of field studies of seasonal and daily dynamics of migrations of lampreys of the genus Eudontomyzon took place.

In the study of diatoms of the genus Meridion in samples from modern reservoirs on Unalashka Island, an employee of the IEE RAS Neplyukhina A.A. and an employee of MSU, DBS Chudaev D.A. discovered and described two species of this genus new to science - Meridion tenuipes and Meridion humerosum.

This article shows for the first time that the vocal repertoire of European red deer males is not limited to rutting roars emitted during the reproductive period.

April 3–6, 2023 the IEE RAS hosted a meeting of the Working Group on data processing to assess ecosystem flows of greenhouse gases in the framework of the most Important innovative project of national importance Scientific and Educational Center "Carbon in Ecosystems: Monitoring".

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.

Scientists from IEE RAS, together with colleagues from Kazan Federal University, described two species of benthic copepods of the order Harpacticoida new to science from water bodies of the Arctic Middle Siberia.

Scientists, including employees of IEE RAS, evaluated the effect of the floor height of a residential building on the amount and composition of urban dust reaching its windows.

logical invasion is the introduction of alien organisms into new regions of the planet. A new type of biological invasion was described when studying the macroecology of the freshwater red-eared slider (Trachemys scripta elegans), which is native to North America.

The Asian mollusk Corbicula fluminea is one of the most successful invaders in freshwater ecosystems. They settled far beyond the borders of East and Southeast Asia - their native range - and spread in the waters of North, Central and South America and in Europe.

Researchers from IEE RAS, Ph.D. E.Yu. Krysanov and Ph.D. S.A. Simanovsky, together with colleagues from France, Canada, and the Czech Republic, studied the differentiation of karyotypes in the group of Nothobranchius ugandensis, which includes 12 valid species.
