Russian scientists continue to analyze signals from the satellite transmitter of the polar she-bear tagged in July of 2019 on Vilkitsky Island. The research is fulfilled within the project “Monitoring of polar bears on islands and coast of Yamal-Nenets Autonomous Okrug” of the Severtsov Institute of Ecology and Evolution and the Russian center for Arctic exploration.
Observations over movements of the female polar bear from the 15th of December of 2019 to the 15th of March of 2020 showed that during three months she hunted seals in the Kara Sea. The bear moved in search for food along the 73rd parallel of the northern latitude, deviating from it only by 160 kilometers. In the longitude direction the animal passed the distance of 400 kilometers, as the press service of the governor of Yamal reports. Thus, on the 15th of January the she-bear reached Dikson Island, spent five days there and returned back to Vilkitsky Island, making a 10-day stop at the northern end of Sibiryakov Island to hunt.
“Analysis of the movements of the female bear and the ice situation from satellite data allowed us to determine hunting time and significant movements in search for new food places”, said Ilya Mordvintsev, a senior researcher at the Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences.
Arrival of the female bear to Dikson Island also shows that satellite signals from transmitters of bears can be used to notify about appearing of wild animals in places, where people live.
Now the bear is located in the area of Vilkitsky Island, which, according to the scientists, is the ideal habitat with enough cracks and space of open water in the ice for hunting.
In July of 2019 a five-year-old female bear with two cubs was also tagged with a satellite transmitter on Beliy Island. A few months later the animal dropped the collar, and on the 15th of December the signal from it stopped coming.
