Multidisciplinary expedition of KarRC RAS scientists underway in the Ladoga skerries region

Employees of the Department for Multidisciplinary Research, Forest Research Institute and Institute of Biology of the Karelian Research Center RAS are conducting field research in the Ladoga Skerries National Park. The expedition is carried by the Poseidon research vessel. One of the tasks is to study the intensity of recreational use of the islands.
The multidisciplinary expedition to the Sortavala District on board the Poseidon research vessel started on July 30. It includes specialists in forestry, botany, soil science, mammals and birds.

– The expedition tasks include research on the biodiversity of plants and animals in island ecosystems, assessment of the current state of the ground vegetation cover, study of the intensity of recreational use of this area in the Ladoga Skerries, – told Nikolai Petrov, Expedition Leader, Secretary for Science of the Department for Multidisciplinary Research (DMR) KarRC RAS.

Fieldwork in the Ladoga Skerries will be completed on August 7th. After that, the data and samples will be processed in the laboratory and analyzed.

The expedition is part of the cooperation between the Karelian Research Centre RAS and the Ladoga Skerries National Park, the agreement for which was signed in November 2023. Collaboration between the organizations involves scientific research and implementation of scientific, conservation, educational, and sociocultural programs and projects.

The Ladoga Skerries National Park is situated on the north-western coast of Lake Ladoga. This protected area was established to conserve the valuable natural ecosystems and to manage their recreational and tourism use. The nomination papers for the park were prepared by specialists from the Karelian Research Centre RAS.

The park's territory, with narrow bays of Lake Ladoga cutting deep into the land, heavily rugged terrain and relatively high rocky ridges, is unique and unparalleled in Russia. Lake Ladoga itself is also a unique water body, being the largest freshwater body in Europe. The park boasts high biodiversity and recreational potential.

Karelian biologists ran successful trials of a technique for detecting fish infection with helminths based on traces of their DNA in water

Specialists of the Institute of Biology KarRC RAS were the first in the republic to test the method of environmental DNA analysis (eDNA) to detect a model fish parasite in an area impacted by trout farms. This is especially important in the context of a growing number of fish farms that use the practice of transporting stock (fry) from between water bodies, which creates a risk of new parasites appearing in lakes. Currently, fish have to be captured and examined to detect an infection, and for the output to be accurate the sample should be at least 15 fish. This may be problematic in the wild and costly in cage facilities. The eDNA diagnosis system can detect the presence of parasites directly in water samples.
