Scientists exploring for fungal strains capable of controlling ixodid tick numbers

Karelian scientists have conducted an experiment where taiga ticks (Ixodes persulcatus) were infected with various strains of entomopathogenic fungi – parasites that affect many groups of arthropods. The strain collected from Bolshoy Solovetsky Island in the White Sea proved to be the most effective: tick mortality in this treatment was 45% on the seventh day and rose to 95% on the eleventh day. The results can be used to develop biologics for controlling the numbers of the main vector of dangerous diseases.

Scientists of KarRC RAS introduce federal and regional mass media to their research objects

Journalists from federal and regional mass media learned about the objects studied by researchers of the Karelian Research Centre RAS on the “Journey to Science. Karelia” press tour organized by the National Priorities NPO. A part of the National Science and Technology Decade is the popular-science tourism program, which gives its participants a chance to actually see how domestic science is developing and to visit research laboratories and fieldwork sites.

Geographer’s Day in an unconventional way at KarRC RAS Environmental Research Museum

Geographer’s Day is celebrated in Russia on August 18th, honoring the foundation of the Russian Geographical Society (RGS) on this day in 1845. So this year is the RGS’s 180th anniversary. In Karelia, the date is also a round-number anniversary — the local RGS branch was founded 80 years ago. To befit the date, Karelian geographers celebrated it in a special manner: an open lecture series was held at the Museum of Applied Environmental Research KarRC RAS.

Karelian scientists resume observations of forest ecosystems in Paanajarvi National Park

Scientists from the Department for Multidisciplinary Research KarRC RAS went on an expedition to the Paanajarvi National Park, where they explored Arctic biodiversity and could compare the development of north-boreal ecosystems in a pristine area not affected by human activities and in forests with more noticeable human impact.

Karelian scientist creates 3D models of ancient stromatolites

Stromatolites are amazing fossils – structures deposited by ancient cyanobacteria in shallow waters billions of years ago. Geologists most often find them in carbonaceous rocks: dolomites and limestone. Some of the most ancient stromatolites have been discovered and explored in Karelia. Their studies have progressed to a new level: a young scientist from the Institute of Geology KarRC RAS Andrey Lyutikov has designed a technique for 3D simulation of the structures.

Scientific conference Precambrian Summit-2025 to take place in Petrozavodsk

The geological conference Precambrian Summit-2025 will be held at the Karelian Research Centre RAS on August 11 to 17. During this conference, organized by the Institute of Geology KarRC RAS, scientists will share expertise and discuss the results of their recent studies on the early history of the Earth.

Scientists pin down a first finding of wolf-dog hybrids in the wild in Karelia

Genetic study of wolves taken down by hunters in Karelia shows hybrids from crossing between wild animals and dogs are appearing in the population. Scientists believe this may be driven by the hunting pressure – a survival strategy for the species. On the other hand, hybridization and inbreeding – crossings between close relatives – jeopardize the population in general. Meanwhile, wolves play a pivotal ecological role.
