title: Dynamics of distribution of introduced mammals in Ukraine and factors influencing them
abstract: This article considers changes in the composition of the fauna and in the abundance of alien mammals from the group of introduced species over the past two decades, which in Ukraine are marked by two powerful processes. These are the distinct processes of climate warming and shortening of winters, on the one hand, and the large-scale war waged by Russia against Ukraine on the territory of Ukraine, on the other. Such changes in the natural environment lead to significant shifts in the boundaries
