This collection presents the proceedings of the 7th All-Russian Scientific Conference with International Participation "Ecosystem Dynamics in the Holocene," which took place at Perm State National Research University.

Losiny Ostrov is a unique nature reserve in the middle of a metropolis. How does it “feel”? What problems does it experience? What animals and plants live there? How should people behave so as not to disturb it?

The Hippoboscidae family currently includes approximately 220 species. One of the most studied groups of blood-sucking flies is the genus Melophagus.

Soil pollution harms flora and fauna. Heavy metals, such as copper, lead, and zinc, are among the most common soil pollutants.

Most of the Bystrinsky Nature Park's water bodies are known to be home to specific salmonids. Understanding their diversity, evolutionary history, population status, and potential risks required specialized scientific research.

A detailed study of crustacean biodiversity in the mangrove swamps of the Cần Giờ Mangrove Biosphere Reserve, located near Ho Chi Minh City in southern Vietnam, revealed a high species diversity of tanaids.

The "Active Child Citizen" platform has launched a survey to choose names for four moose — the symbols and pride of Losiny Ostrov National Park.

Researchers from the IEE RAS, the Mara-Meru Nature Reserve in Kenya, and LMSU have described for the first time the vocal repertoires of adult and cub wild cheetahs from Kenya.

We live in an era when animal and plant species are rapidly spreading beyond their native ranges due to human activity.

Radiography is one of the most promising methods for non-invasively determining the age of animals. In this study, the researchers applied it for the first time to live rodents from a wild population.

Rosneft environmentalists have developed a standard corporate program for biodiversity conservation in all regions where the Company operates.

A new study, conducted by researchers from the TIINRD SB RAS and the IEE RAS, summarizes the results of nearly thirty years of fieldwork in the region (1993–2022).

The Moscow Department of Environmental Management and Protection continues its collaboration with scientists to study the capital's flora and fauna.

Researchers at the IEE RAS have described a new amphipod species of the genus Niphargus Schiödte, 1849 — Niphargus primoricus Marin & Palatov, 2025.

Many soil animals, superficially similar, actually belong to different species. These so-called cryptic or "hidden" species play an important role in soil functioning but remain undetected by traditional research methods.

In the first half of September 2025, a working trip by staff from the IEE RAS to the People's Republic of China took place.

IEE RAS staff presented their papers at the "Evolutionary Biology" section. Both papers generated considerable interest and discussion, as they examined the survival characteristics of animals in urban environments.

The conference was held in the hall of the National Genghis Khan Museum, which opened in 2022 in Ulaanbaatar.
