The exhibition “Karelia. History in Stone” at the National Library of the Republic of Karelia will present a variety of exhibits: solidified lava, fragments of the ancient sea bed, hematite ore specimens, etc. Through these exhibits visitors will be able to connect to the history of the Earth and learn what Karelia looked like billions of years ago: how many volcanoes there were around the present-day Petrozavodsk, what lake was formed by meteorite impact, where the traces of an ancient sea beach in the Klyuchevaya district come from, and a lot more.
During April, visitors will be offered lectures and master classes: to examine minerals under a microscope, to learn how stones differ from each other, and to trace their path from a body of rock to a piece of interior design.

Scholarly geologists to give a series of lectures and master classes within the “Karelia. History in Stone” exhibition
The exhibition “Karelia. History in Stone” prepared by the Institute of Geology KarRC RAS is set to open at the National Library of the Republic of Karelia on April 6. It will introduce visitors to natural features found around Petrozavodsk: traces of volcanic eruptions, marine sediments and evidence of the origin of early life forms. During the month, scientists will be giving lectures and master classes at the library.

A successful introduction: the zander has settled down in Lake Sundozero and continues to spread
Scientists of the Institute of Biology KarRC RAS have published the results of long-term observations over the population of the zander (or pikeperch) introduced to Lake Sundozero more than a half-century ago. They confirm the species has become naturalized. Maintaining the population requires regulation of harvesting, protection during spawning, and tending of spawning grounds.

Ice-related phenomena on rivers emptying into the White Sea now last three weeks less than 60 years before
Ice on northern rivers now forms later while ice-off occurs earlier. Karelian scientists confirmed this having analyzed 64 years of marine and meteorological data from the estuaries of rivers draining into the White Sea along its western coast. Climate change has bit three weeks off the ice-covered period on these rivers. The reductions have been the most significant in the last 30 years, aligning with global warming trends in Arctic water bodies.

Citizen science and web technologies help researchers study insects of Karelia
More than 30 insect species not encountered in Karelia previously have been revealed by entomologists from KarRC RAS during their expeditions and using data communicated by active participants of the iNaturalist portal – an open platform for collecting biodiversity data.
