How long have scientists been studying musk oxen in YaNAO? What interesting things did they notice about the behavior of large animals? These and other questions were answered by a researcher at the A.N. Severtsov Institute of Ecology and Evolution RAS, candidate of biological sciences Sofia Rosenfeld. She also spoke about genetic studies of animals that had developed at the same time as mammoths and about how many of them live in Yamal: freely and in enclosures.
