Bogoyavlensky Yuri Konstantinovich
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.
How scientists find a balance between studying Baikal seals and protecting them from humans
Photo: Alexander Vedernikov, Kommersant The Baikal seal is the only seal in the world that has fully adapted to life in fresh water. This endemic is not only a key element of the Lake Baikal ecosystem, but also an indicator of its health. However, due to climate change, increased tourism and anthropogenic pressure, the seal population is facing new challenges. How do scientists study these animals? Why do they use drones to count seals? What are the most serious threats to the species and how can they be minimized? Kommersant-Nauka spoke about this with Maria Solovyova, head of research on Baikal seal research programs, senior researcher at the Institute of Ecology and Evolution of the Russian Academy of Sciences, and candidate of biological sciences. — Why is it important to observe Baikal seals? — The Baikal seal is a unique species of seal. It is the only species that has fully adapted to life in fresh water. The ringed seal, for example, has subspecies — the Ladoga and Saimaa seals, which are also freshwater, but this is only part of the species, not the entire species. Due to this adaptation, the seal's diet has changed, for example, because Baikal is home to completely different fish, behavior, and lifestyle. Baikal is currently a place of intensive tourism development, and understanding how the seal is affected by the intensification of Lake Baikal use will allow us to more competently approach the conservation of this unique endemic. The Baikal seal can act as an indicator of the health of the entire ecosystem. It is a consumer of the highest order in the lake and is at the top of the reservoir's food chains. Any changes at the lower levels of the lake pyramid inevitably affect it, and the seal itself affects the underlying components. In addition, there is such a thing as "fundamental science". Scientists are simply interested in everything. There are animals - Baikal seals. How do they behave? Why do they behave this way? Do they behave the same way throughout the year? This is an internal interest that pushes us to conduct research. — Why do scientists use drones to count seals, rather than traditional observation methods? What are the advantages and limitations of this approach? — We combine these methods in our work. On Tonky Island, where our camp is based and where the tourist trail to the seal haulout is located, we count them visually. But because of this, we cannot count those animals that are underwater at the time of the study. In addition, the Ushkany Islands archipelago consists of four islands, and seals haul out not only on Tonky Island. Therefore, to count animals on Tonky Island, as well as on two more islands - Dolgy and Krugly - we also use drones. It is difficult to conduct foot counts on Dolgy and Krugly Islands: the coast is not always passable, plus to conduct the counts it would be necessary to go there three times a day in a noisy boat, which would additionally frighten the hauled out seals. — How do on foot accounts on Tonkiy Island complement the data obtained from drones? Are there possible discrepancies in the counts? — They allow us to count animals more accurately, as well as note externally noticeable parameters: molting, scars or injuries on animals. We conduct such visual counts during field work three times a day, which allows us to also assess changes in the number of lying animals during the day in order to identify at what hours the seals prefer to rest and at what hours they prefer to swim. There are discrepancies in the data because during visual counts we do not count seals underwater, and when counting from a drone, we sometimes have a worse view of seals on rocks: in order not to scare the animals, we have to fly at a high altitude. But combining these methods gives us results that are closer to reality. — Why wasn't Bolshoy Ushkany Island included in the flyovers? How could this affect the overall estimate of the seal population? — We use small drones with a flight time of up to 30 minutes in light winds and high air temperatures. Bolshoy Ushkany Island is located at a distance from the three small Ushkany Islands, and our drone's operating time is not enough for a full flyover of this island. Yes, most likely, we are not taking into account the seals that are located near Bolshoy Ushkany Island. But, according to our observations from the vessel and information from the Federal State Budgetary Institution "Zapovednoye Podlemorye", not as many seals haul out there compared to the others. — How do scientists assess the health of seals (injuries, molting)? What conclusions can be drawn from this data? — We assess the presence of injuries and molting visually during foot counts. The molting fur of Baikal seals is reddish, as if faded, and it is very clearly visible against the background of molted gray animals. Injuries are also visible: most often, seals have injuries to the eyes, front flippers, and scars on the body are also common. According to our data, the proportion of both molting and injured animals on Tonky Island is small. Molting is a normal process, and for some animals it can drag on until June-July every year, there is nothing wrong with that. Injuries are also, unfortunately, a part of the seals' lives: they could have received them in fights with each other. We pay special attention to anthropogenic injuries - for example, noticeable scars from boat propellers. Fortunately, we hardly see them on the islands yet, but we need to monitor them so that their numbers do not increase. — What long-term consequences can periodic stress surges in seals have for the population? — If we talk about stress in the sense of "anxiety, tension in the body," then, of course, it does not pass without consequences for anyone, even for seals. But, if you dig deeper, stress occurs because of something. If a seal experiences stress from lack of food, then the consequences of such stress will also be the consequences of hunger. If stress consists of a lack of rest due to the lack of places to lie down, then there will be all the consequences of the lack of recovery of the body, including weakened immunity, improper production of hormones and enzymes, or, for example, a decrease in cognitive abilities. — How could the early melting of ice and the mass death of seals in the past affect their stress resistance? — Here we need to clarify: what early melting of ice are we talking about, what mass death of seals? If we mean a less cold winter, which periodically happens on Baikal, then the consequences of such a winter will be the following. Seals need ice in winter for the birth and feeding of offspring, new mating, rest and the beginning of molting. If the ice lasts less time than usual, this can lead to incomplete feeding of the cubs and a lack of rest in animals. Weak ice can break more often, which leads to separation of the mother-cub pair. Small amount of ice forces seals to huddle more, that is, to unite in dense groups. This can lead to a wide spread of various diseases - like in humans during a pandemic, remember? It was important to keep your distance. Mass deaths of seals, which have occurred several times in the past, lead primarily to a local decline in the population. — Why are there fewer seals on Tonky Island than on other islands, contrary to previous data? What environmental or anthropogenic factors could have led to such a redistribution? — Most likely, there is no point in talking about a redistribution of seals. It is unlikely that there are fewer seals on Tonky Island: previously, regular observations were simply not carried out on other islands. — What measures could reduce the disturbance of seals by tourists and shipping? Are the existing restrictions effective? — Our observations on the islands show that the greatest disturbance to seals is caused by boats and vessels, which scare seals from their haulouts with their noise. Most often, these are people swimming by — not tourist groups that come to the archipelago in an organized manner. It is necessary to raise public awareness so that they reduce their speed and engine noise when moving near the islands. Tourist activities on the islands are strictly controlled by the staff of the "Zapovednoye Podlemorye" and, judging by our observations, do not cause much disturbance to the seals. On Tonkiy Island, a special wall has been installed, from behind which tourists can observe the seals, remaining unnoticed by the animals. — How do private foundations (for example, the Lake Baikal Foundation) contribute to the conservation of seals? — In order to preserve, we need to study. In 2018, the Lake Baikal Foundation initiated the creation of a program for research on the Baikal seal and its habitat and has since been a permanent partner of the program with the support of the World Around You Foundation of the Siberian Wellness company and other private donors. In addition, the foundation carries out huge educational work with the population: in 2019, it conducted a large campaign, “Year of the Baikal Seal,” with trips to schools and the creation of an online lesson on the seal. The foundation also works with an adult audience — with its support, publications appear on the careful treatment of the animal, and this year it was possible to shoot the first popular science film in Russia about the Baikal seal, “The Seal and Man,” where we acted as invited experts—the heroes of the film. But the main thing is that the foundation attracts the missing resources for the study of the seal and does this on a regular basis. — What other threats besides tourism can affect the Baikal seal population? — Climate change is the most significant. As I said above, ice is critical for the Baikal seal. And in recent years, we have seen a reduction in the duration of ice cover and the degree of ice development. This was especially noticeable in the winter of 2024–2025: the winter in many regions of Russia was warm and with little snow, and on Baikal, vehicles were allowed onto the ice for a record short time. Time will tell whether such changes are local or a trend. Water pollution also has a significant impact. The seal closes the food chains of Baikal and is a consumer of the highest order. Therefore, if pollutants enter the lake's ecosystem, they will accumulate as they move along the food chain, and the seal will accumulate the largest amount of them. — What new technologies besides drones could improve seal monitoring? — Currently, there are no deciphered maps of the ice cover of Lake Baikal in the public domain. Such maps exist for the Arctic and Antarctic, but they are not available for inland waters of Russia. There are satellite images, but in order to determine the characteristics of the ice, such as its type and density, we need highly specialized experts, which, unfortunately, we do not have on our team. It would be good to put more advanced satellite transmitters on the animals that measure the depth of dives, the percentage of time that the seal spends in and above the water. But they are not yet produced in Russia. — Why is the program designed specifically for 2020–2025? Will it be continued and what key issues will remain unresolved? — No program should be planned for an indefinite amount of time: specific deadlines are needed by which the results obtained will be assessed and further steps adjusted. Of course, we plan to continue work on the program and formulate a new one for 2026–2031, taking into account the issues that will remain unresolved after the 2025 expedition. — How can the data from this expedition influence environmental decisions at the state level? — Environmental protection agencies regularly contact scientists on specific issues. For example, in 2024, when the issue of the need for industrial seal hunting arose, a joint meeting of the RAS Scientific Council on the Problems of Ecology of Biological Systems and the Scientific Council of the Siberian Branch of the Russian Academy of Sciences on the Problems of Lake Baikal was held at the A. N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences, where all Baikal seal experts expressed their opinion on this issue and formed a resolution recommending abandoning this idea. In 2025, we plan to continue studying the impact of tourism on Baikal seals. The result of the research should be the development of special rules for tourists - on how to observe the Baikal seal correctly and comfortably. We intend to implement this task together with experts from the Federal State Budgetary Institution "Zapovednoye Podlemorye" with the support of the Lake Baikal Foundation. Maria Gribova
Memories of Sofia Vasilievna Goryunova, an employee of the Institute of Microbiology of the USSR Academy of Sciences
Fig.1: Goryunova S.V. We bring to your attention the diary entries made in 1941-1943 by a junior research fellow at the Institute of Microbiology of the USSR Academy of Sciences, PhD Sofya Vasilyevna Goryunova (born in 1907). They tell the story of the scientists who remained in Moscow while most of the staff left for evacuation. Fig.2: 1936 Expedition. Institute N.I. Vavilova Goryunova S.V. Diary entries from 1941-1943 in the author's edition During daytime alarms at the institutes, except for those on duty at their posts, everyone went down to the basement floor, where the library and reading room of the Department of Biological Sciences were located (where our library still is now). Fig.3: Bitsevsky S.-H. technical school of seed production Goryunova S.V. 1928 The mass camouflage painting of buildings greatly changed the familiar appearance of Moscow. Often, instead of one, you would see two different buildings, completely different from each other. Or, in their continuous row, there would appear empty spaces that you had not noticed before. Factories, plants and institutions, including our Institutes, sent more and more people, mainly young women, to the labor front - to build defensive fortifications of the Mozhaisk line and the Moscow defense zone. By the beginning of October, Moscow had sent about 300 thousand people to defensive work. Fig.4: Bitsevsky S.-H. technical school of seed production Goryunova S.V. group photo On many boulevards, squares and even large vacant lots the first balloons appeared, never seen or even heard of by us before, and with them girls in military uniform. Somewhere in early or mid-September, the Moscow militia was hastily formed from party and Komsomol members at the district party committees. We sadly said goodbye to our former Komsomol members, young scientists who had just joined the party and who, as they said then, showed promise: Petya Kolesnikov from the Institute of Biochemistry and Kostya Ovcharov from the Institute of Physiology, Ya. Khudyakov (Institute of Microbiology), Patrushev and Kushner (Institute of Geography), Katunsky (Institute of Plant Physiology), Sadovyi (Institute of Animal Morphology) and many others, who were sent to the front in the first days of the war. (You can now read about the fate of some of them on the website of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences). Fig.5: In the office of Goryunova S.V. Moscow was under martial law! Evacuation points worked around the clock to send women with children and the elderly deep into the country. Fig.6. Director of the Institute Isachenko. Before 1941. Goryunova S.V. On Bolshaya Kaluzhskaya Street, one could sometimes see herds of cows and sheep slowly walking along it, which were evacuating somewhere to the east “on their own” from the western side. Fig.7. In the department. Goryunova S.V. with other employees. From the beginning of the constant air raids, the characters of the Institute employees began to change noticeably. Some literally suffered mental shock and had to leave Moscow immediately. Others, who were not brave in peacetime, and even had a timid character, for example, A.G. Melnikova (PhD, senior research fellow at the laboratory of Corresponding Member A.N. Butkevich) - turned out to be steadfast, courageous fighters in civil self-defense groups, standing at their posts during the bombings, on roofs or in the yard, under a tiny wooden umbrella, throughout the long night of alarm. Fig.8. Isachenko, Director of the Institute. Before 1941. Goryunova S.V. Since August, the Presidium of the Academy of Sciences (USSR) has been sending elderly and infirm academicians and corresponding members with their families to Central Asia, to a resort in Borovoe. The evacuation of women with children of scientific employees (or family members) has also been ongoing. Thus, Gromyko, Rukina, Garkina and some of our other employees left for the Urals. Fig.9. Goryunova’s house on Miusskaya street In September, all Moscow institutes of the Biological Department of Sciences began preparing for departure to Kuibyshev. We carefully packed books, manuscripts and scientific diaries, instruments, reagents and laboratory glassware. Fig.10. Head of the expedition on the scientific ship Vityaz Goryunova S.V. Autumn in 1941 came very early and was damp and cold. Literally from the first days of October it began to rain almost continuously, sometimes with snow. It was felt that there would be a harsh winter. In Moscow, a collection of warm clothes for the army was announced everywhere. At our Institute, we also tried to collect as much as possible. People willingly brought their sweaters, fur hats with earflaps, and those who could – men's winter underwear, felt boots. And almost everyone found mittens or warm woolen socks. Everything was carefully counted and stored in the room of research fellow Kriss. Fig.11. Head of the expedition on the scientific ship Vityaz Goryunova S.V. There were fewer and fewer people left at the Institute. The difficulties of wartime were growing. Somewhere in the middle of the first ten days of October, an alarming rumor suddenly spread that the Germans were approaching Moscow and, apparently, had already occupied Yakhroma. And that armed squads were already being organized at the factories. Is that true? For some reason, it was precisely these first three weeks of Moscow October that were drowned in a mysterious informational haze. But, apparently, something very big and important had happened? The historical date, in my opinion, was approaching - October 16, 1941! As always, I arrived at the Institute for work on time that day, i.e. by 10 o'clock. Nevertheless, our deputy director for scientific affairs, M.N. Meisel, who was replacing the director at that time, was already waiting for me there. Fig.12. Goryunova S.V. in Podlipki Since I was a biochemist and our laboratory at that time, unlike all the others, had practically the only well-functioning fume hood in the Institute, I received an order from him to destroy (by burning) all the personal files and correspondence of the Institute. A huge pile of folders was already in my room. To burn everything under a small draft (after all, in the past it was Professor Kizel's office and in one day?!) was not an easy task. And I, on the one hand, by some intuition - taking advantage of the general chaos in which the Institute had been for the last few days, freed myself from most of this difficult and ignoble work, running around all the laboratories and asking people to choose their papers from this pile (many of them were later so grateful to me for this "initiative"). Indeed, who better than the owners themselves can store their documents? And if necessary, won’t they have the time and opportunity to burn them themselves?! But I still had to destroy some of the general affairs and correspondence – admittedly, quite ordinary (after all, in those days, in our institutes, so small compared to today's, there was nothing secret) – I still had to destroy it. I burned all day. True, sometimes I was distracted by conversations and all sorts of other things – fortunately, the authorities did not check up on me. But still, it turned out that I was, apparently, the last to leave the Institute. And since our laboratory was the second from the entrance, I did not even look back as I ran away. The next morning, as always, suspecting nothing, I quickly got ready and rushed to my institute. On the way, I was, however, somewhat surprised by the streets of Moscow. It seemed to me that for some reason they were more crowded than usual. But... maybe it just seemed that way? Where could free people come from at such a time? However, when I entered the Institute, I was dumbfounded! The scene that appeared before me could easily be called "the Battle with Mamai"! All the doors were wide open. In the office and accounting department, there were open, empty safes. (In the office, Sondak kept precious metals in the safe: platinum wire for crucible and cup sowing). In the office, there were salaries for the employees that had just been received from the bank. In the preparation room, there was a mass of broken dishes and garbage. All the warm clothes that we had so conscientiously collected for the army had disappeared from Kriss's small laboratory. And, of course, the Institute's property was scattered around, packed in boxes and piled up! And most importantly – there was no one around! I was alone! Having wandered these strange ashes that only yesterday were our institute, I returned to my laboratory again, and in great confusion and bewilderment sat down in the chair in front of Kizel’s desk. How long I sat there: an hour or two – I don’t remember! But suddenly the door opened slightly and someone’s strange snub-nosed face stuck into the resulting gap. And a cheerful young voice asked: “Who are you?” I answered: “And what do you want here?” The visitor turned out to be a young soldier. Not at all offended by my unfriendliness, he squeezed through the door and started a friendly conversation with me, telling me that this morning on Bolshaya Kaluzhskaya Street and even further beyond the outpost all the official buildings were empty. And he and his comrades, who by this time should already be next to him, had just visited the All-Union Central Council of Trade Unions, where all the doors were also wide open, and watches and many other valuables, which the trade unions usually awarded to shock workers, were scattered haphazardly on the tables. My new acquaintances were among those who were now on patrol duty to protect this abandoned state property, including our academic property, and had arrived to take up their posts. However, this confidential conversation of ours was suddenly interrupted by another daytime alarm. My new acquaintances hurried to their commander, and I, out of habit, went down to the basement. And... Oh, joy! Before even reaching the library, but only through the glass doors, I saw people there. And what people! Among others - my old biochemist acquaintances: A.L. Kursanov, the permanent (under Oparin) scientific secretary of the Institute of Biochemistry N.N. Dyachkova, and my university classmate Nina Kryukova. They were also very surprised when they saw me. And Andrei Lvovich Kursanov exclaimed with genuine amazement: "Sonya, are you here too?" I, still not suspecting anything this time, laughingly answered: "Of course, I'm here too!" Fig.13. Goryunova S.V. with her department Then some light and informal conversation began, far removed from current events. And then the all clear sounded. The alarm turned out to be false, that is, the German planes did not break through to Moscow this time. And we all together, in a crowd, poured out onto the street to quickly fly to our places. By the way, when we were leaving the building, I noticed that our watch, like the day before, was at their duty posts, and there were no soldiers in the building anymore. On the way home, I was again struck by the abundance of unoccupied people on the Moscow streets. Just like on holidays. And rather lively, even. It turns out that on that famous October 16, 1941, when trains with government institutions were preparing to leave or had already left Moscow, panic began in the city (!!). And what is amazing is that only the "party elite" fled. Naturally, first of all, those who had cars or other means of transportation at their disposal. Fig.14. Award to Goryunova S.V. True, at about nine o'clock in the evening on October 18, the radio had already broadcast a strict order for the immediate return of all those who had abandoned their posts. But despite this, the situation in the capital was astounding! On October 19, as always, I went to the institute, but the situation there was already different. Gradually, during the day, about two dozen employees who had not managed to leave had gathered. Among them were M.N. Meisel, deputy director for research, senior research associates, candidates of science - E.N. Odintsova, P.A. Agatov, A.A. Egorova and E.N. Mishustin - the only professor among us. We all again, on Meisel's orders, began packing equipment, reagents, materials, etc. Two weeks later, two freight cars were received. Meisel posted a list of those who had been evacuated. It did not include Butkevich and Isachenko's employees, Mishustin and Agatov's groups, and some others - including me. Meisel justified this refusal by saying that my parents are very old and will not survive the difficult road. What he told others - I don't know. So, I was left with two old people and my 18-year-old sister Irina, with 25 rubles of my father's pension. Fig.15. Orders and awards of Goryunova S.V. At that moment I had no money, no prospects for getting any work: everything that could be closed was closed! That's when the Russian proverb came into play: "A man is truly known in trouble." Thus, E.N. Mishustin showed unexpected concern for us, for all of us who remained. Being a man of remarkable energy and enterprise, he found a workshop somewhere where it was possible to glue gas masks for the army. He himself got a job as a foreman, and enrolled us all as members of the brigade. But there was a misfire here too. An order from the Presidium of the USSR Academy of Sciences unexpectedly arrived "on the immediate evacuation of employees with academic degrees." I was unexpectedly saved by A.A. Egorova, the closest assistant and employee of our director (B.L. Isachenko), who barely knew me then. It turned out that as a specialist in water microbiology, she received a military subject related to the analysis of drinking water and therefore remained in Moscow. (I am still grateful to her for this. And not only for this. How much more wise and kind advice she later gave me and taught me not only to understand, but also to preserve the valuable things that science and culture give us). She was the one who petitioned the director for me. Soon an order came that I was to remain in Moscow as the Institute's authorized representative, i.e. the custodian of its building and the remaining property. Such authorized representatives appeared in other Institutes as well. At the same time, we were also part of the civil self-defense group. The Presidium monitored our activities. Fig.16. Orders and awards of Goryunova S.V. After a week or two, the Institutes of the Department gradually began to fill up with military units. Downstairs, on the first floor, in the Institute of Paleontology, there was a reconnaissance unit. Opposite, in the Institute of Animal Morphology, there was a chemical unit. On our second floor, all the laboratories of the Institute of Genetics and half of the premises of our institute were occupied by a repair unit. How the chemical unit lived - I have no idea. But the scouts were remembered for a long time. They were tall, healthy, all of them young men, hunters from Siberia and former prisoners. And in reconnaissance, perhaps, even irreplaceable. Well, in addition to that, boys - lovers of thrills and romance. Their commander, a captain by the last name of Sugarenko, was also amazing. A very active man of about 40-45 years old. He literally adored his unit and looked after each member. He collected everything he could from our institutes for them: undelivered warm clothes, skis, and everything else that could be useful. He tried to feed them as much as possible. And they, especially on dark November and December days, went on missions straight from us, already in white camouflage suits, in groups or individually. (After all, the German force landed in Fili somewhere at the end of October. The Mozhaisk and Volokolamsk directions of the fronts appeared daily in all reports. Moscow was under siege). And when they returned alive and well, then, according to the old Russian tradition, having had a glass of vodka, they had fun and shot at the ceiling in their barracks. I just don’t know what kind of cartridges they used? Fig.17. Orders and awards of Goryunova S.V. Our repair unit repaired damaged vehicles right on the move, i.e. from the front line – fortunately the academic garage was nearby (B. Kaluzhskaya, 31). Sometimes the vehicles also had machine guns and other weapons, which were stored in the room of the junior command staff (in our office). Fig.18. Goryunova S.V. Head of the expedition. The driver drove into a parked bus. Many months of treatment. As everyone remembers - now old-timers - the winter of 1941-1942 was unusually long and very severe. Frosts reached 25-30 degrees, and there were no thaws. Spring came somewhere in the middle of May and was more than cool, as it was later all summer. And then there was a hitch with electricity, and in January (1942) the steam heating pipes in our building began to burst. After all, at that time the heating plant was still so low-powered that its share of maintenance accounted for some hundredths, and maybe even thousandths of a percent. Moscow was heated by countless individual boiler houses running on coal, and hot water was supplied to the upper floors by electric motors. Fig.19. Goryunova S.V. Head of the expedition. The driver drove into a parked bus. Many months of treatment. This winter was very difficult for all of us, with its countless alarms. One – the duty alarm, the permanent one: from six in the evening until six in the morning. And short-term, unregulated daytime alarms. The latter were especially annoying because they completely disrupted the already anxious rhythm of our lives. For example, we stand in line for bread. We stand for an hour or two. And suddenly the sirens start to blare, the store closes. We hide in the nearest bomb shelters. After lights out, we stand in line again. And again the alarm. And after all, they are waiting for bread at home! Fig.20. 1961 Kislovodsk, Goryunova S.V. At that time, the Muscovites received invaluable help from the wheat flour given out to each family member, I don’t know on whose initiative, at the end of October or in November. Without it, everything could have turned out differently. It became easier by spring. There were no bombings, although there were alarms, but as they said then – “false”. German planes were already flying beyond Moscow, to Gorky. But the front line was still very close to Moscow – only a hundred or a little more kilometers. Fig.21. Goryunova S.V. at the celebration in the department In the first half of May, we all received land for vegetable gardens. The plots of the Academy of Sciences employees occupied the area near the modern building of the Moscow department store, where today, along Leninsky Prospekt (in the back), there are: the clinic and hospital of the USSR Academy of Sciences (house 50a), next to it the maternity hospital and other buildings adjacent to them, as well as the Palace of Pioneers. After all, back then, along Kaluga Highway, in addition to the village, in this part of the avenue there were only two large buildings: the All-Union Central Council of Trade Unions and, almost opposite, the Institute of Fungicides and Pesticides. Somehow, the military units also left the building of the Department of Biological Sciences unnoticed. In their place, and in the same laboratories, we temporarily had employees from the bombed-out academic institute of "Human Physiology" in Kitai-gorod move in. Its director at that time was the only female academician in our country, Lina Solomonovna Stern. In the other empty half, one of the rooms was occupied by A.A. Egorova with her lab assistant L.V. Yarmolyuk. Thus, the three of us already formed a small team. Life was gradually getting better, although false alarms, and therefore the duty of members of the self-defense group, continued. In this regard, I cannot help but mention here that in Moscow, during this most difficult time of the first two years of the war with fascist Germany, all those who remained in it were somehow unusually united, i.e. the morale of Muscovites was very high. It is enough to recall that during the most difficult months of the siege, during alarms, most apartments remained unlocked. Since the experience of the first days of bombing showed that the air wave, having no barriers, causes less destruction. In extreme cases, windows and doors were thrown open. And with such temptation - there was no looting in the city! Fig.23. Goryunova S.V. receiving awards But time passed, and everything returned to normal. By the autumn of 1943, Moscow had become completely calm. All the institutes had returned from evacuation. After the first months of fussing about placing employees in laboratories, unpacking and installing equipment, establishing the smooth operation of the preparation room and other auxiliary services, the institute finally felt the familiar rhythm of the team's work.

Ornithologists have counted very few pairs of rare demoiselle cranes on the right bank of Astrakhan
Photo: JeLuF According to the results of the first stage of the project to preserve the demoiselle crane (Anthropoides virgo), ornithologists have recorded only a few pairs of birds listed in the Red Book of the Russian Federation on the Astrakhan right bank. The reasons for the decline in the species' numbers are long-term drought and poaching along migration routes. The results of the first stage of the project to preserve the demoiselle crane were summed up by ornithologists from the Severtsov Institute of Ecology and Evolution Problems of the Russian Academy of Sciences (IEE RAS), the Nature and People Foundation, and the World Around You Foundation of the SiberianWellness company. In April, ornithologists examined demoiselle crane nesting sites on the Astrakhan right bank in the Chernoyarsky, Yenotayevsky, and Narimanovsky districts of the Astrakhan Region. Scientists encountered only two pairs of nesting cranes, and local residents reported seeing several pairs. The results confirm that the demoiselle crane, listed in the Red Book of the Russian Federation, is disappearing in the European part of Russia at an alarming rate. Ornithologist, expedition participant, head of the laboratory for biodiversity conservation and bioresource use at the Institute of Ecology and Evolution of the Russian Academy of Sciences Valentin Ilyashenko is confident that while demoiselle cranes could adapt to climate change or agricultural practices, as was the case in the last century, it is hunting in Saudi Arabia that has a very strong impact on populations. "No less than a thousand cranes are hunted annually per season," the scientist stated. According to him, farmers in the Astrakhan Region are understanding of the scientists' request to install low drinking bowls, which are used by demoiselle cranes in addition to lambs. Following the first stage of the expedition, specialists also noted a large amount of plastic film near melon plots, especially near the canals running from the Volga in the Chernoyarsk district on the border with Volgograd. Many plots are contaminated with plastic waste. By the end of autumn, ornithologists plan to study nesting sites of demoiselle cranes in the Saratov and Volgograd regions, Kalmykia and Dagestan.

Field environmental research has begun in the urban part of the Losiny Ostrov national park
Scientific research has resumed in the part of the Losiny Ostrov National Park within the territory of Moscow. During environmental field work, specialists study the biological diversity of water bodies and the state of populations of rare species of animals and plants. "Research work is very important for preserving the nature of the capital's park territory. The city closely monitors the biodiversity of this unique territory, where more than 300 species of animals of different groups live, and over a thousand plants grow. The natural complex is under close control. At the same time, scientific research data helps to shape the vector of development of the territory both in terms of species conservation and in terms of environmental education of citizens," said Yulia Urozhaeva, head of the capital's Department of Nature Management and Environmental Protection. Comprehensive large-scale studies of the park's nature began last year. They are being conducted by a group of more than 80 scientists, including representatives of the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences. "In 2024, at the request of the Moscow Government, we carried out a comprehensive survey of the capital's territory of the national park, collected a large array of data on rare and alien species, on the diversity of terrestrial and aquatic ecosystems. A concept for preserving ecosystems was prepared, a program of measures was developed, this year we will implement this program and continue the research," said Andrey Reshetnikov, PhD in Biology, head of the hydrobiology section, senior researcher at the laboratory of behavior of lower vertebrates at the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences. This year, scientists began their research by studying the biodiversity of water bodies using the Babaevsky Pond as an example. They took samples of phyto- and zooplankton, as well as benthic organisms living in the soil of the reservoir. Work with the samples will continue in the institute's laboratory. Specialists will determine how many species, for example, planktonic crustaceans and rotifers, and in what quantities, currently live in the reservoir. In the process of studying the pond ecosystem, scientists also want to clarify which representatives of lower vertebrates are currently present in it. This primarily concerns amphibians that come to spawn in the spring to lay eggs. Last year, researchers already identified a number of species of plants and animals that are not typical for the metropolis on the Moscow territory of Losiny Ostrov. For example, several populations of an amphibian rare for Moscow, the common toad, were discovered in the reservoirs. During the first field study this year, scientists recorded the presence of toads in Babaevsky Pond for the first time. Comprehensive ecosystem monitoring of the Moscow part of Losiny Ostrov is carried out to assess the well-being of biogeocenoses, their condition and dynamics. This is important in order to control the condition of populations of rare protected animal species, as well as to track possible penetrations of invasive species into ecosystems. The Moscow part of the Losiny Ostrov National Park is a unique natural area. Its peculiarity is that it is located partially within the boundaries of the largest metropolis in Russia. It is also home to an urban population of moose, which includes more than 10 individuals. It is almost impossible to meet these large animals in large cities of the world. Also, species listed in the Red Book of the city of Moscow live here, including the Aurasian hobby, the great crested newt, red wood ants, the emperor dragonfly and others. Educational work in this area is carried out by the Krasnaya Pine eco-center of the capital's Department of Nature Management and Environmental Protection. Ecological walks and excursions are organized for visitors. Photo: M.

Krylov Petr Semenovich
We continue telling the stories of the employees of the IEE RAS who participated in the Great Patriotic War. From July to September 1941, Krylov Petr Semenovich (since 1939 - a student of the Moscow Agricultural Academy named after K.A. Timiryazev) participated in the construction of the first line of defense of Moscow in the Smolensk region as part of student battalions. In September-October 1941, as part of the student detachment of the Timiryazev Agricultural Academy, on assignment from the People's Commissariat of Agriculture of the USSR, he worked on harvesting in the Saratov and Stalingrad regions. Then he was drafted into the Red Army. From April to May 1942 - squad leader. From May 1942 to March 1943 - cadet of the Stalingrad Military School of Communications. After graduating from the school, he was the head of the radio station of the headquarters of the 25th Guards Mechanized Nizhyn Order of Bohdan Khmelnitsky Brigade of the 7th Guards Nizhyn-Kuzbass Order of Suvorov Mechanized Corps of the Reserve of the General Command (as part of the 1st Ukrainian Front) from March 1943 to May 1945. He participated in combat in the Battle of Stalingrad, on the Oryol–Kursk Bulge, in the liberation of left-bank Ukraine, in the battle of the Dnieper, in the liberation of Kyiv and right-bank Ukraine, near Königsberg, in Poland during the battle of the Oder, liberation of Warsaw, Krakow, Czestochowa, in Czechoslovakia during the liberation of Prague, in Germany in the Berlin operation. In 1943, he was wounded in battle during the battle of the Dnieper. After the end of the Great Patriotic War, he served in the Soviet Army in Germany, Czechoslovakia, and Hungary. Demobilized on December 1, 1945 from Budapest. For bravery, courage and bravery demonstrated in combat operations against the Nazi invaders, he was awarded two Orders of the Red Star, the Order of the Patriotic War 1st degree, medals "For the Victory over Germany in the Great Patriotic War of 1941-1945", "For the Liberation of Prague", the Zhukov Medal, and jubilee medals.
Are microplastics in soil harmless to earthworms?
Fig.1: Microplastics in earthworm coprolites: a, b and c — L. rubellus; d — A. caliginosa (scale bar — 1 mm) Plastic pollution of the planet is one of the most serious environmental problems of our time. Plastic causes diverse and well-documented harm to aquatic ecosystems, from small invertebrates to fish, seals, and seabirds. Soils are also subject to large-scale plastic pollution, but its impact on soil inhabitants remains a subject of debate. A team of scientists from the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) and the Senckenberg Museum of Natural History (Germany) found that exposure to relatively large fragments (1–5 mm) of high-density polyethylene does not lead to weight loss in two common species of earthworms. The study used the soil-dwelling, endogeozoic species Aporrectodea caliginosa and the leaf litter-feeding, epigeozoic species Lumbricus rubellus. It was assumed that ingesting plastic particles, which have no nutritional value, would cause weight loss in earthworms by diluting the food substrate (the so-called food dilution hypothesis). Despite initial expectations, in an 8-week experiment, the presence of plastic in the soil did not affect the body weight of earthworms, even at high concentrations (up to 2.3 weight percent in soil for A. caliginosa and up to 48 weight percent in leaf litter for L. rubellus). Both earthworm species actively ingested plastic particles, but no negative effects were observed. It is likely that since plastic entering the soil has physical properties similar to various natural components of organic and mineral origin, it acts similarly and does not cause significant harm to soil inhabitants. This is a sharp contrast to the aquatic environment, where microplastics act as a “physical xenobiotic” that has no direct analogues, and explains why many studies of the effects of plastic on soil animals do not reveal any significant negative effects. However, long-term negative consequences cannot be ruled out, especially if plastic breaks down into smaller and potentially more dangerous nanoparticles. The study was published in the journal Environmental Science and Pollution Research (Leonov, V.D., Zuev, A.G., Zueva, A.I., Sotnikov, I.V., Tiunov, A.V. (2025). Exposure to mm-scale microplastic particles does not cause weight loss in two earthworm species belonging to different ecological groups. Environ Sci Pollut Res. Fig. 2: Experimental design. Earthworms of two species were placed in small plastic containers with soil for eight weeks. For earthworms A. caliginosa, the microplastic was mixed into the soil (0.3 or 2.3 wt%); for litterworms L. rubellus, the plastic was mixed with aspen litter (33 or 48 wt%). In addition, in half of the microcosms, the feeding conditions of the worms were improved by adding organic matter to the soil (for earthworms) or fragmenting the litter (for litterworms).
