Candidate of Biological Sciences, Leading Researcher of A.N. Severtsov IEE RAS Ilya Mordvintsev talked about the current state of research and plans for the future.

Established in 2022, the Evolutionary Trophology Laboratory specializes in the study of feeding habits, digestion and parasites of fish, amphibians and reptiles living in various natural conditions from the Arctic to the tropics.

Documentaries "Sterkh. Return to Kunovat", "Saiga races" and "Musk ox reacclimatization in Yamal" are available freely.

How long have scientists been studying musk oxen in YaNAO? What interesting things did they notice about the behavior of large animals? These and other questions were answered by a researcher at the A.N. Severtsov Institute of Ecology and Evolution RAS, candidate of biological sciences Sofia Rosenfeld.

Members of the genus Nothobranchius live in the temporary reservoirs of the East African savannas and have one of the shortest life cycles among vertebrates, which makes them a unique model for studying a variety of biological processes.

On January 10, the constituent assembly of the public association "Expert Council on Reserve Affairs" was held in the Public Chamber of the Russian Federation.

“Pikas” can refer to birds as well as mammals. The mammal ones are small creatures resembling hamsters. However, their closest relatives are hares and rabbits: they are included in the same order, Lagomorphs. Most pikas store hay for the winter (haypiles), which gives them a common denomination of “haystackers”.

Leopards released at the end of July have mastered a significant part of the territory of North Ossetia, especially forest areas, but, judging by the data received, they are not going to stop there.

Assessment of the hormonal status in animals has been carried out in recent decades not only in the blood and organs, but also in various excretions (feces, urine, saliva, milk, hair).

It is “profitable” for parents to produce offspring from a partner more distant in terms of MHC genes, providing maximum heterozygosity for the offspring, which increases its survival rate.

Perennial studies of the migration activity of lamprey allow on the one hand to detect new patterns and mechanisms of this phenomenon, and on the other, to adjust already established ideas about the migrations of this group of animals.

Understanding the structure of the species, especially when it comes to complexly organized species represented by different forms, is impossible without knowledge about its life cycle.

Researchers of the IEE RAS Parasitology Center together with specialists from the “United Directorate of Taimyr reserves” conducted a study on the feces of wild reindeer deer (Rangifer Tarandus) to find out which helminths parasitize them.

The Afar Triangle is a unique tectonic formation where the Red Sea Rift, the East African Rift Valley and the Aden Range intersect.

In early December, Jose A. Hernandez-Blanco and Taras Sipko, members of the IEE RAS, together with the Expedition-Tour company and the financial support of Igor Dontsov, completed the next stage of the expedition to study the behavioral ecology of the wolf and ungulates of Kolyma.

The tradition of studying the wolf in the Soviet Union and Russia has deep roots and its own history. In the 70-90s of the last century, a group of wolf cub specialists actively worked in the country, which then turned into the Commission on Large Predators at the Theriological Society.

Engineering nanomaterials are widely used in various fields of human activity. Thus, silver-based nanoparticles are widely used in medicine, agriculture, and cosmetics.

The venoms of predatory marine molluscs of the genus Conus are being studied intensively due to the biomedical applications of conotoxins, the neuropeptides they contain.
