Conducted at the Glubokoye Ozero N.Yu. Zograf hydrobiological station of IEE RAS, the school-conference was a continuation of a series of seminars-schools on the taxonomy and faunistics of cladocerans (the first school-seminar was held in 2008, the second - in 2013, the third - in 2018). On the other hand, it was a continuation of a series of conferences on cladocerans and other crustaceans of continental waters, held on the basis of the I. D. Papanin Institute for Biology of Inland Waters of RAS. In 2021, it was decided to transform the school-seminar into a school-conference, because of the restrictions due to the COVID19 epidemic, no other large events specifically dedicated to cladocerans are planned in the near future, and the presentation of the latest results on them for fellow carcinologists looks quite appropriate. Unlike previous schools, the 2021 school conference was attended almost exclusively by specialists for whom cladocerans are the primary object of their professional activity. The school-seminar was attended by 12 people - employees of IEE RAS (M.A. Aksenova, O.S. Boykova, P.G. Garibyan, A.G. Ibragimova, N.M. A. Neplyukhin), the Faculty of Biology of Moscow State University (A.Yu.Sinev, E.S. The participants were somewhat contingently divided into “teachers” and “students”, since in many cases the “students” were able to explain important aspects of the cladocera identification process to their colleagues themselves. The main purpose of the event was to acquaint the participants with the latest achievements, problems and methods of work in the field of taxonomy and faunistics of this group of micro-crustaceans.

Congratulations from the institute to Fyodor Vitalievich on his position!

This year, the Hydrobiological Station at Lake Glubokoye celebrates its 130th anniversary. The hydrobiological station on Lake Glubokoe, the first in Russia and one of the first scientific freshwater stations in the world, was established in 1891 under the auspices of the Imperial Russian Society for the Acclimatization of Animals and Plants, a public organization that existed and operated almost exclusively on private donations. Professor N.Yu. Zograf, the founder of the station, was at that time chairman of the Ichthyology Department of the Society. Lake Glubokoye was assigned the role of a model reservoir, “where the invertebrate fauna and other components of the biota will be studied in all details and in relation to the fish population, for this knowledge to be transferred to other reservoirs”. Moreover, the biological station was assigned the role of an experimental and acclimatization base. The presentation on the history of the biostation is available through this LINK.

Specialists of the project to restore the population of the Central Asian leopard in North Ossetia began to apply new methods of animal monitoring. The new technique was applied in connection with the need to search for the female Agura. In March, the GPS information from her collar stopped working, and before that the collar of the male Baksan stopped sending signals. Satellite transmitters could be damaged while hunting wild ungulates, or they could have had technical problems. But on both collars, radio beacons continue to work, the signals from which scientists have recorded from time to time during ground monitoring. Therefore, it was decided to search for animals using a radio signal from the air. For this, special equipment was selected to amplify the signal, and with the help of a light aircraft, flights were carried out over the territory of North Ossetia. On the plane, on both sides of the board, special antennas were fixed, which makes it possible to pick up the signal both to the left of the flight route, and to the right, as well as in front. This arrangement of equipment increases the likelihood of detecting animals.

On May 26, the editorial office of Komsomolskaya Pravda hosted a press conference "Marine mammals and fishing - how to maintain a balance of interests." The speakers at the conference were Deputy Head of the Federal Agency for Fisheries Vasily Sokolov, Academician of the Russian Academy of Sciences Vyacheslav Rozhnov, Deputy Director for Research of the Federal State Budgetary Scientific Institution VNIRO Vyacheslav Bizikov, as well as Tatyana Shulezhko, an expert of the Association of Longline Fishing, who joined the discussion via video link from Kamchatka.

Chunkov Magomed Magomedrasulovich and his scientific advisor Kamil Zubairovich Omarov, Doctor of Biological Sciences, Associate Professor, Chief Researcher of the Laboratory of Animal Ecology of the Caspian Institute of Biological Resources - a separate subdivision of the Federal State Budgetary Scientific Institution of the DPhIC RAS On Tuesday, May 25, 2021, in the conference hall of the A.N.Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (Leninsky Prospekt, 33) Chunkov Magomed Magomedrasulovich defended a thesis for the degree of candidate of biological sciences on the topic of "Features of the ecology of the Radde hamster (Mesocricetus raddei avaricus) in the changing nature of land use in Gorny Dagestan." The defense of the thesis was successful. Congratulations to Magomed Magomedrasulovich! The dissertation abstract is available here.

Olga Shpak, specialist in marine mammals, researcher at the A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) took part in the online meeting "Whales. Disappearing Giants". The Sea of Okhotsk, at the latitude of Moscow, is home to an unusual population of bowhead whales, or polar whales, and is endangered. Would you like to know more about the peculiarities of these whales and the means of their preservation? Video recording of the webinar is available.

Why do we sleep? What is the brain doing during sleep? What happens to our consciousness when we sleep? Mankind has been asking these questions for thousands of years and is still looking for answers. But today somnology is developing at an incredible pace. But dreams remain a mystery to us, and the more we study it, the more confusing and interesting this mystery becomes. Sleep is the most ancient and, apparently, a vital state that originated at the dawn of evolution. An analogue of slow human sleep - a "dreamlike" state of rest - appears already at the level of annelids and insects. Recently there was an article by British authors describing a study on fruit flies. Among almost a thousand female fruit flies, sleeping on average 5 hours a day, scientists have found not only a handful of flies in a “sleeplike” state, but even three individuals sleeping 15, 14 and even 4 minutes a day! By all accounts, they should have died very soon. But they live day after day, week after week without problem. And the life of the fruit fly is about 40 days. Therefore, this sensation is being discussed by the entire scientific world. This study again posed a question that seemed to have been answered long ago - can a person live without sleep? For now, the answer seems to be no. A mammal, especially a human, is not a fly. Physiologically, we need sleep, moreover, we vitally need both of its phases - slow and fast sleep, without them a person cannot think, his consciousness unable to function.

In the fall of 2020, a group of scientists from IEE RAS led by Ph.D. Olga Shpak departed for Wrangel Bay with an interesting task: to install satellite transmitters on whales in order monitor their migration routes and winter habitats, test a new way of taking a biopsy - using a drone, replenish the photo catalog of whales and try to assess the influence of tourists on the population under threat of extinction. It was planned to put satellite tags on animals in an unusual way - from a motorized paraglider. It turned out to be not at all easy, as the pilot Alexander Bogdanov vividly tells. This is a film about an amazing place - the Shantar Islands. This place is one of the few on the planet where people can come into contact with whales in the literal sense of the word. Expedition organizers: Institute of Ecology and Evolution A.N. Severtsov Russian Academy of Sciences (IEE RAS), Project “Trace to Preserve”: Understanding the Seasonal Distribution of Threatened Bowhead Whales to Identify Potential 'Areas of Conflict' with Economic Activities The project was supported by the Ocean Park Conservation Foundation Hong Kong (OPCFHK) The film was shot with the support of the “Splav” company https://www.splav.ru/ and the “Far Eastern Expeditions” http://fetravels.ru/.  

A.N. Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, will sign an agreement on cooperation within the framework of the world-class Marine Scientific Center. On June 3, in the hall of the board of the Federal Agency for Fishery, an organizational meeting of the World-class Marine Scientific Center (NCMU) took place. The event was attended by the heads of scientific and educational organizations of the Federal Agency for Fishery and the Russian Academy of Sciences, as well as the technical partner of the NCMU - GC "Antey". The establishment and activities of the Center are regulated by the Decree of the Government of the Russian Federation. The project was supported by Russian President Vladimir Putin. "Breakthrough solutions for creating an advanced fishing industry can only be found through joint efforts of academic and applied science with the involvement of high-tech companies. The Marine Science Center will become an organizational form of this integration," said Ilya Shestakov, head of the Federal Agency for Fishery. The NCMU is faced with the tasks of developing new promising technologies for the extraction and processing of Antarctic krill, fish and invertebrates, algae, technologies for industrial aqua and mariculture, technologies for the production of medicinal food products. A promising direction will be the decoding of the genomes of deep-sea organisms with a unique metabolism in order to be used for marine pharmacology, aquaculture and agriculture. During the meeting, an agreement on cooperation will be signed between all participants of the NCMU: - All-Russian Research Institute of Fisheries and Oceanography (VNIRO)

Sofia Borisovna Rosenfeld, senior researcher at IEE RAS, took part in the film "Red-breasted Goose. Flying over Manych", which is now available for viewing. The life of the red-breasted goose is subject to strict laws of movement, reproduction and nutrition. They raise their offspring on a limited patch of tundra of Russia, and fly to wintering sites and back along the beaten paths of heaven with obligatory long stops for feeding. And one of these stops is the Kumo-Manych depression. What dangers await them on the way and how they are studied will be described by experts.

The project aimed at environmental education of the population initiated by the IEE RAS in North Ossetia within the framework of the Leopard Restoration Program in the Caucasus (Leopard Restoration in Ossetia) was evaluated and became a finalist for the Crystal Compass award in the Enlightenment nomination. The project is being implemented jointly by the IEE RAS and the Ministry of Natural Resources of the Republic of North Ossetia-Alania with the participation of regional media and the support of RusHydro. The VIII and IX Crystal Compass awards ceremonies took place at the Moscow International House of Music on May 27, 2021. The prize has been awarded since 2012 for outstanding achievements and unique projects of our time, which are aimed at preserving natural, historical and cultural heritage. The motto of the award is “Protect the Future”. The authors of the nominee project are A. Yachmennikova, A. Alibekov, M. Slanova, A. Dzhenikaeva, V. Tokhsyrov, M. Nagoga.

Biologists from the A.N.Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (Moscow) and the I.D.Papanin Institute for Biology of Inland Waters of the Russian Academy of Sciences (Borok), in collaboration with scientists from the State University of New York, studied the sequences of several genes of the water fleas of the genus Bosminopsis and reconstructed their evolutionary history. It turned out that first representatives of this genus originated in the time of the dinosaurs. This study is one of the stages in the formation of new ideas about the biogeography of freshwater animals in Eurasia. The article was published in the journal PeerJ with the support of the Russian Science Foundation (RSF), the press service of the foundation briefly told about the results of the study. Water fleas, or branched crustaceans, are microscopic, no more than six millimeters, animals, and the size of representatives of the bosminid family is even less than a millimeter. They are so widespread that individual representatives can be found even in Antarctica. In total, about 850 different species of water fleas are known today. They are used as food for aquarium and industrial fish and as indicators of the toxicity of aqueous solutions of chemical compounds. In addition, the genome of water fleas provides extensive material for research, since it contains more than 30 thousand different genes, which, for example, is 5-10 thousand more genes than in humans.

In the Stepnoy Wildlife Refuge (Astrakhan Oblast), the work of a group of employees of the A.N. Severtsov Institute of Ecology and Evolution RAS (IEE RAS) under the leadership of RAS Academician V.V. Rozhnov continues the tagging of newborn saigas with ultra-light ear tags that do not cause disturbance to the animals. This is a continuation of the development of the technology for studying the movements of saigas using scientific equipment installed on the Russian segment of the ISS. While tagging the saiga calves, not a single animal was harmed. Earlier, we reported on the cooperation of the IEE RAS with the Max Planck Institute of Animal Behavior, Germany, the Institute of Geography of the Russian Academy of Sciences and RSC Energia, within the framework of which the employees of the IEE RAS take part in the implementation of the Russian-German project ICARUS. The goal of this project is to organize global monitoring of the movement of animals from space in order to understand the reasons for their movements and to understand the complex processes taking place in ecosystems. At the end of 2020, the first five transmitters were tested on adult saigas. In agreement with the partners and after obtaining the necessary permits, it was decided to tag saigas with miniature ICARUS Basic Tag Solar / GPS devices powered by solar batteries that were placed on the animals’ mammalian ear tag platform.

On the scientific expeditionary vessel "Mikhail Somov" two lectures were held by the staff of the Institute of Ecology and Evolution of the Russian Academy of Sciences, who are in charge of the expedition for the "Narwhal" project. Ilya Murashev spoke about the ecology and bird diversity of the high-latitude Arctic. Svetlana Artemieva - about marine mammals. Svetlana, a research associate of the Narwhal project and a leading engineer at the Institute of Ecology and Evolution of the Russian Academy of Sciences, has been studying marine mammals for many years and is capable of, almost by a wave surge, distinguishing who is under the water: a humpback or a killer whale, a porpoise or a bowhead whale. Seals, walruses, beluga whales, ringed seals, polar bears (also marine mammals), narwhals - each species has its own characteristics and mysteries. Why do narwhals have teeth yet walruses tusks? Who is ready to eat their seal relative? What whales run away from the ship by swimming on their backs? Where are the "carding places" of marine life? Is it necessary to save the seal pups caught on the ice during the ice drift? And how to become a marine biologist? These two lectures have more purposes than education. Members of the Arctic Floating University can help the Narwhal project with the observation of birds and marine mammals. Students and their supervisors are constantly observing for their projects, divided into watches: the weather, the ice, the sea debris, the birds ... And it may well turn out that they will spot a whale or even a narwhal. The information and photos derived from their observation will be of great value to the colleagues as well.

This question from the project "My Planet" is answered by Maria Erofeeva, Ph.D., Senior Researcher, Laboratory of Behavior and Behavioral Ecology of Mammals, IEE RAS. Where the saying that a cat has nine lives, and not seven or, for example, ten, came from, is not known for certain. This is probably due to the fact that the number 9 has often appeared in myths, legends and has long been considered magical, since it closes the cycle 1-9. Perhaps the agility of this predator and the ability to land on four legs led to the fact that people began to attribute magical abilities to it. However, in reality the cat only has one life. It's just that nature has endowed the animal with a good sense of balance. Thanks to the developed vestibular apparatus, cats are not afraid of heights and can deftly walk on cornices, roofs and other heights. If they are to fall, they turn over in the air with their back up, spread their paws wide to the sides and land on all fours. As a result of such a maneuver, the surface of the body increases and the fall slows down as the "parachute effect" is triggered. The tail acts as a balancer in flight. But this does not mean that cats without a tail are doomed. Such animals have learned to use their hind legs to maintain momentum. In addition to a sense of balance, a flexible spine helps cats roll over in the air and spread their legs wide. Some have put forward opinions that cats do not have collarbones and that is why they are less injured when landing on their paws. It is not true. Cats have collarbones, but they are attached only on one side, which makes animals more flexible. For example, dogs cannot spread their paws this wide.
