Scientists have obtained the first data on the spatial distribution, size composition, age, sex structure, growth and maturation of a poorly studied deep-sea benthopelagic fish species – Coelorinchus gilberti.

A key feature of tailless amphibians (Amphibia: Anura) is their complex life cycle, in which the terrestrial adult form is separated from the aquatic larval stage by metamorphosis.

Blood-sucking flies of the genus Ornithomya Latreille, 1802 (Diptera: Hippoboscidae) inhabit mainly the middle latitudes of the Old World. They are parasites of birds, especially birds of prey.

Hepatitis E diseases cause the death of more than 40,000 people annually. Both ungulates and rats can be reservoirs of this pathogen, which indicates the zoonotic potential of rodent hepeviruses.

Cladocera occupy an intermediate link in the trophic web between primary producers (algae) and consumers (planktivorous fish).

Over the course of three days, lectures and practical classes were held in the IEE RAS laboratories as part of the educational track "Marine Biodiversity: Methods and Directions of Study".

We congratulate all researchers who study birds, as well as scientific volunteers and hobbyists!

An international team of scientists has revised the modern ichthyofauna of Tajikistan and analyzed the changes that have occurred over the past century.

On February 6, research fellow, DBS L. A. Limantseva and postgraduate students of the Laboratory of Phytoparasitology of the IEE RAS conducted an excursion for participants of the Competition of specialized classes.

Scientists have obtained for the first time data on a rare fish species - the Alaskan sculpin Triglops metopias (Cottidae) from the Russian waters of the Kuril Islands.

Deputy Director for Science, Corresponding Member of the RAS A.V. Surov and Scientific Secretary of the IEE RAS, DBS N.Yu. Feoktistova took part in the discussion "Gone Viral!" about how to distinguish real animals from those generated by neural networks.

The annual Readings in Memory of Academician Vladimir Evgenievich Sokolov were held at the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences.

Among migratory insects, butterflies and dragonflies are the most well-known, but their migration routes have been poorly studied so far.

The forest canopy is inhabited by a variety of invertebrates, some of which are traditionally considered to be soil dwellers.

Among the many animal species, only a few have abandoned males and switched to unisexual reproduction.

Cases of catching two individuals of the three-toothed lamprey in the northwestern Pacific Ocean have expanded our knowledge of the morphological characteristics and biology of this species during its marine life.

Information on the current state of habitats and the degree of their suitability for the species in different parts of its range, which in the Russian Caucasus is its northwestern edge, is in great demand.
