From May 5 to 12, Corresponding Member of the Russian Academy of Sciences, Professor of the Russian Academy of Sciences, Chief Researcher of the Laboratory of Aquatic Community Ecology and Invasions of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) A.A. Kotov held a series of lectures for 7th-8th grade schoolchildren of the "Biological Shift" at the Sirius Educational Center (Sirius Federal Territory). The lectures were devoted to the problem of invasive species in marine and continental water bodies, as well as the work of hydrobiologists. One of the lectures was called "Why Study Small Crustaceans?" The schoolchildren showed great interest in the reports and asked the lecturer many "children's" and very "adult" questions. A.A. Kotov separately spoke about the activities of the IEE RAS.

An international team of scientists has studied the consequences of global warming in the Arctic, combining a large pool of long-term data on 12 populations of 9 bird species. The work was attended by an employee of the Bird Ringing Center of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS), senior researcher, PhD in biology Sergey Valerievich Volkov. Global climate change is most clearly manifested in the Arctic, the increase in average annual temperatures is more than twice as high as in temperate regions. Earlier snowmelt and ecosystem development affect the established connections in communities, disrupting traditional interactions. To compensate for the negative consequences of desynchronization between different phenomena, migrating birds have to optimize their migration strategies, including shifting wintering areas closer to nesting sites, starting from wintering grounds earlier, increasing the speed of migration, and reducing the duration of intermediate stops. However, the question remains whether such changes lead to earlier arrival to nesting areas or earlier reproduction. The publication demonstrates patterns of earlier migration and reproduction as a response to warming. However, against the background of warming, the unpredictability of conditions in each specific season limits the fine-tuning of Arctic bird migration to annually changing conditions. The study "Migratory birds advance spring arrival and egg-laying in the Arctic, mostly by travelling faster" was published in the prestigious international journal Global Change Biology.

Senior researcher at the Laboratory of Behavior and Behavioral Ecology of Mammals, PhD in Biology Anastasia Antonevich took part in the Naukogradostno festival, which was held in Chernogolovka on May 17-18. Anastasia Antonevich spoke at the round table "Science and Art: Creating Worlds." She spoke to the participants about how studying animal behavior and possible evolutionary origins of art help to understand the origins of creativity. You can watch the recording of the round table at the link.

The atlas contains the first full account of information on all 202 species of animals belonging to 37 families from 7 orders living in the western part of our country. This is the first edition that includes maps of all species of land-dwelling, water-dwelling and flying mammals at the same time. All maps are provided with a QR code, by clicking on which you can see all the encounter locations of a particular species. For each species, the map provides data for the entire period of zoological observations. The maps are accompanied by species essays that allow you to get an idea of ​​the animal's appearance, its ecology, variability, the place of the Russian population in the world range, as well as its practical significance and conservation status. The atlas is illustrated with drawings by the famous animal artist V.M. Smirin. The authors of the species essays were 89 leading theriologists of Russia, representing scientific organizations, universities, and nature reserves of our country. "The Atlas of the Distribution of Mammals in the European Part of Russia" was published by the well-known scientific publishing house - "KMK Scientific Publishing Partnership". The atlas is intended for a wide range of readers. It is useful for anyone whose work includes studies of mammals: teachers, nature lovers, professional zoologists and ecologists, specialists working in the field of nature conservation, hunting, epizootology and agriculture. The publication was prepared over the course of seven years by the Academician V.E. Sokolov Working Group of the Theriological Society at the Russian Academy of Sciences, which included specialists from the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences, the Research Zoological Museum of the M.V. Lomonosov Moscow State University, the Professor B.M. Zhitkov All-Russian Research Institute of Hunting and Fur Farming, Penza State University and the Southern Scientific Center of the Russian Academy of Sciences. The data included in the "Atlas of the Distribution of Mammals of the European Part of Russia" was collected using the "Mammals of Russia" information system. The data entered into this system was divided into several categories: museum collections, observations of zoologists and naturalists, data from literature and reports, and information from the Internet. Volunteers made a significant contribution to the study of the distribution of individual species by adding their findings to the "Mammals of Russia" portal database. Work on studying the distribution of Russian mammals will continue. In the future, it is planned to publish "The Atlas of Distribution of Mammals of the Asian Part of Russia" and "The Atlas of Distribution of Mammals of Russia". We invite all caring people to contribute to the knowledge of the animals of our country and add their findings to the "Mammals of Russia" information system.

Congratulations to the veterans of the Great Patriotic War and colleagues on Victory Day! 80 years have passed since the Victory in the Great Patriotic War. The generation of people who defended our right to life and freedom, who rebuilt the country destroyed by the war is inexorably passing away. It is our duty to remember the feat of these people and preserve the memory of them. By May 9, the IEE RAS opened the exhibition "Scientific Regiment. 80 Years of Victory". It presents information about the activities of the Institute during the Great Patriotic War: about the employees of the Institute who did not return from the war, as well as those who fought at the front, worked in the rear, and conducted scientific research in evacuation. The exhibition includes biographies of individual employees and tells about the national economic, defense and medical work that was carried out during these years, about the contribution of scientists to bringing the end of the Great Patriotic War closer. And also about the continuation of fundamental scientific research, which did not stop, despite the severity of wartime. The exhibition is open in the Institute building on Leninsky Prospekt 33 on the first floor (near the library). We have a section on our website where we tell about the Institute employees who took part in the Great Patriotic War. This year we updated the memory album about the Institute employees who took part in military operations, home front workers, all those who brought Victory closer. We have also organised a subsection with stories of the Institute employees who took part in the Great Patriotic War. We have published these stories in the news over the past three weeks. You can see them in one place by following the link. We wish you good health, well-being and fruitful work!

Fig. 1. The first edition of Schmalhausen’s book in 1946. The history of the Great Patriotic War is shocking not only because of the colossal destruction in the places of military operations and the death of a huge number of people. The manifestations of courage, fortitude and creativity in literally all spheres of the country's life, which played their own roles in achieving victory, are amazing. Time reveals new sides of the nation's feat not only in the military archives made public in recent years, but also in open, exclusively "civilian" sources of information such as Wikipedia. In connection with the celebration of Victory Day and the publication on the website of our Institute of frontline and everyday stories from the lives of wartime employees, such facts of the past as state awards to rear scientists deserve attention. In June 1945, literally a month after the victory, the work of the director of our Institute, Academician I.I. Schmalhausen, who was evacuated from Moscow at the beginning of the war along with other leading academic scientists, was highly rewarded for his work during the war. He was awarded the Order of the Red Banner of Labor (https://ru.wikipedia.org/wiki/Шмальгаузь,_Иван_Иванович). And in 1946, Schmalhausen's outstanding work, the book "Factors of Evolution" (Fig. 1), was published. The book is considered a milestone in the development of the synthetic theory of evolution. This work integrated the achievements of the period of genetics, which Schmalhausen himself characterized as "dizzying successes" (https://arran.ru/exposition8_10?ysclid=lrgyy6d8pq550159945), into the discussion of evolutionary problems. The publication of the book in 1946 coincided with another state award being received: an employee of the institute, geneticist Raisa Lvovna Berg, was awarded the medal "For Valiant Labor in the Great Patriotic War of 1941-1945." 6 works by R. L. Berg, during her doctoral studies as the only geneticist at the Institute of Evolutionary Direction, published in 1941-1943, are included in the bibliographic list of the aforementioned monograph by her scientific advisor I. I. Shmalgauzen. Fig. 2. Raisa Lvovna Berg in 1940. Paradoxically, during the period of the defeat of Soviet genetics, inspired by T. D. Lysenko and his supporters at the 1948 session of the All-Union Academy of Agricultural Sciences, Berg, like most geneticists, was fired from her job (she remained practically unemployed for six years). The same fate befell Academician Shmalgauzen. Both, however, were able to overcome trials that did not exist even during the war, without tearing their lives away from science. The list of publications by R.L. Berg in the book “Factors of Evolution” (Schmalhausen, 1946) is given according to the library copy of the original edition: 1941 - Genetic analysis of two natural populations. Zhurn. Obshch. Biol. 2, No. 1. 1942 - Preservation of different mutability by populations of Drosophila melanogaster when they are transferred to the same conditions. DAN. Vol. 34, No. 7. 1942 - Relationship between mutability and the degree of isolation of populations of Drosophila melanogaster. DAN. Vol. 36, No. 2. 1942 - The significance of isolation for the evolution of dominance in natural populations of Drosophila melanogaster. DAN. Vol. 36, No. 9. 1943 – Correlation between mutability and regulatory capacity of the organism and its evolutionary significance. DAN. 1943 – Different frequency of occurrence of the yellow mutation in different populations of Drosophila melanogaster. DAN. Compiled by PhD Bulatova N.Sh.

From April 24 to 30, 2025, the final stage of the All-Russian School Olympiad in Biology was held on the federal territory of Sirius at the sites of the Scientific and Technological University and on the campus of the Sirius Educational Center, in which about 500 schoolchildren from 87 regions of the country took part. The jury included employees of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) Anastasia Mikhailovna Khrushchova, Varvara Ivanovna Krolenko and Lyudmila Andreevna Vakalyuk. The chronicle of the Olympiad is available on the official website bio.siriusolymp.ru

Today we will share another story of an employee of the IEE RAS who participated in the Great Patriotic War. Bogoyavlensky Yuri Konstantinovich was born on May 8, 1925 in Moscow. When he was three years old, his mother died. In 1935, his father was invited to work at the newly created Kursk Medical Institute, and before the war, Yuri lived and studied in Kursk. Together with the employees of the institute, he was evacuated to Alma-Ata, from where he was drafted into the Red Army on February 14, 1943. First, he studied at the infantry school, then was transferred to the Serpukhov Aviation School (Kyzyl-Orda) from where he graduated with honors, having received the specialty of aircraft mechanic. From 1944 to 1946, he served as an aircraft mechanic at the 164th Central Air Base in Koenigsberg. Demobilized in April 1947. Received the military rank of senior lieutenant. He was awarded the medal "For Victory over Germany in the Great Patriotic War". After demobilization, Yuri Konstantinovich followed in the footsteps of his father, a doctor of biological sciences. From 1947 to 1952, Yuri studied at the Faculty of Biology and Soil Science of Moscow State University, and from 1952 to 1955, he was a postgraduate student at the Institute of Evolutionary Morphology and Ecology of Animals of the USSR Academy of Sciences, and was a student of Academician K.I. Skryabin. His main scientific works are devoted to the problems of helminthiasis and its treatment, as well as the functional micromorphology and histochemistry of helminths. He is the founder of a scientific school in the field of helminthology. Using histological, electron microscopic and histochemical methods, he studied the structure and functions of various tissues and organs in representatives of more than 60 species of parasitic nematodes and some species of cestodes and trematodes. He discovered the osmotic pathway of nutrition of intestinal nematodes through the system of canals in the cuticle. He discovered and described the supporting fibrils that ensure the attachment of muscle cells of parasitic nematodes to the cuticle. He studied the structure and functions of the neurosecretory apparatus in helminths of different classes, and showed that the intensity of neurosecretion depends on the physiological state of the parasites. He studied the problems of phylogenesis and taxonomy of parasitic worms. He made a significant contribution to the development of new chemotherapeutic drugs with anthelmintic action. He was active in expeditionary work as the head of helminthological and parasitological expeditions.
