详细

Based on 30-year collection of red fox skulls from the Middle Urals, the north of Kurgan oblast, and the south of Tyumen oblast, an increase in average values of craniometrics characters has been revealed in both young and adult animals of both sexes. This increase shows a weak but statistically significant correlation with annual average temperature. The rates of increase in different characters are not equal.
