The research plans for the 2022 field period were discussed by Kronotsky State Reserve officials and scientists from third-party research institutes were invited, RAI KAMCHATKA-INFORM told the reserve.

More than 20 on-site research topics are scheduled at the annual scientific and technical council, dozens of staff and volunteers will take part in the missions.

Kamchatka’s unique protected nature attracts the attention not only of tourists from all over the world, but also of scientists. Volcanologists call Kamchatka a “natural laboratory.” Ichthyologists obtain unique research results and make new evolutionary hypotheses by studying the emergence processes of endemic fish. Terologists are interested in studies of both marine and terrestrial mammals. Only in 2022, in the reserves of Kronotsky and Koryaksky, the refuge of South Kamchatka, research will be carried out with the participation of scientists from the Institute of Inland Water Biology. ID Papanin RAS, Pan-Russian Institute of Fisheries and Oceanography Research, Botanical Institute. Institute of Ecology and Development VL Komarov named after VLAN Severtsov RAS, the Institute of Pacific Geography of the Far East Branch of the Russian Academy of Sciences, the Institute of Volcanology and Seismology of the RAS branch of the Russian Academy of Sciences.

 

Among the mammal studies this year, one can note a large-scale aerial survey of the brown bear, which will soon take place at the South Kamchatka refuge. The concentration of “Kamchatka craftsmen” cutlery is very high here. Earlier in the Chronicle of Nature, scientists noted that more than 120 people could be counted in 2-3 hours of aerial surveys in the Kuril Lake area.

For the first time in recent years, a count of large-horned sheep and a study of the population of black-roofed marmots will be carried out (both species live on mountain peaks, volcanic plateaus and high-slope slopes on the sea shore). Reserve researcher Evgenia Volkova is conducting the work. the number and sex and age of the animals, their behavior and their habitats will be studied. “Snowfall and the black-roofed marmot are among the basic species of the shelter. We will conduct studies on these species at two locations: the Taunshits and Krasheninnikov volcanoes along the gorge, the foothills of Schmidt volcano, and the estuary. “Kozlova on Opolzneva hill along the bighorn sheep,” says Eugenia.

“We have not counted sheep large horns since 2012,” added Daria Paniceva, head of the reserve’s science department. – This is a rather large gap in our Chronicle of Nature. Studies on the black-headed marmot have also not been conducted in recent years. Evgenia Volkova’s task is to restore regular work at the aforementioned model sites. ”

In the summer, research on salmon fish will continue in the reserve, conducted by ichthyologists Grigory Markevich and Evgeny Esin. The first phase of the research, which is scheduled for this year, took place in March. Scientists are looking for spawning grounds for the stone and studying its biology. The stone is a reptile of predatory fish that lives in the canal and tributaries of the Kamchatka River, endemic (ie it is not found anywhere else). This is a unique example of the formation of new species in river ecosystems. Most scientists agree that this fish is a descendant of the widespread Dolly Varden dough. The number of stone coals is rapidly declining, so it is included in the Red Book of the Kamchatka Territory. “Finding places where coal is born is extremely difficult. So far, only three spawning grounds have been found in the reserve area. Of course, a much larger number of breeding sites, observations and samples are needed to expand this kind of knowledge. “Also this year, work is planned on the Istok enclosure of the Kronotsky Shelter and in the Kronotsky Lake basin to search for new relics and study such a salmon form as kokanee,” said Grigory Markevich, a senior researcher at the reserve. . The rock char study is supported by WWF Russia.

In addition, in the field of ichthyology, this year will continue the long-term joint work of KamchatNIRO with scientists from the Kronotsky Reserve. From May to October, project participants will watch the river salmon herd. Ozernaya and its habitat in the territory of the South Kamchatka refuge, as well as for the study of the structure of the spawning stock of sockeye salmon on Lake Kurilskoye. Such work allows us to ensure a more sustainable use of fishery resources, to understand the acceptable volumes of salmon catches that will not harm the future of this valuable salmon fish.

Thanks to the support of PAO NOVATEK, in 2022 large-scale work will continue to study the population of wild reindeer in the area. Its main task is to develop measures for the rehabilitation of the population. After a catastrophic decline in the number of deer on the peninsula in recent years, the only large herd of about 500 heads has survived on the territory of the Kronotsky refuge. In cooperation with NOVATEK, the reserve organizes aerial surveys to help determine the current population and age and sex structure of the Kronotsko-Zhupanovsky wild reindeer herd, as well as additional genetic material studies.

Other studies this year include observations of geysers and other hydrothermal vents, as well as studies of landslides and landslides in the Geysers Valley and the Ouzon Caldera. study of island arch deformations under the sinking conditions of some edges of lithospheric plates below others (geologists call this sinking). study of the role of volcanic-hydrothermal systems in the central part of East Kamchatka in the formation of the river flow in the Kronotsky Bay of the Pacific Ocean. study of the composition, properties and dynamics of gaseous-hydrothermal fluids in the Koshelev hydrothermal-magmatic system. study of pyroclastic products (that is, what erupts a volcano) of the largest volcanic eruptions in the territory of the Kronotsky reserve. insect research, many works on whales and seals at the same time and much more. A number of scientific works this year are carried out with new methods, such as hydroacoustic equipment, video recordings and modern data processing software. And of course, all scientific missions are organized with minimal load in physical groups.
