摘要

摘要研究了对车里雅宾斯克州草原山猫（Mustela eversmanii）数量的长期监测。鼬科动物的数量动态分析是以每年进行的冬季核算（WA）方法的监测数据为基础进行的。在过去几年中，在山区泰加林的统计工作中没有记录到草原极猫，也就是说，其数量要么极少，要么完全消失。从 2008 年到 2020 年的 12 年间，森林-草原地区的极猫数量减少了近 90 倍，从 3058 只减少到 34 只。本文介绍了草原鼠兔的主要猎物物种--两种地松鼠（Spermophilus major 和 Spermophilus pygmaeus）和土拨鼠（Marmota bobak）的数量数据。还考虑了美洲水貂可能对草原极猫数量产生影响的假设。

Depression of the Population of the Steppe Polecat (Mustela eversmanii) in the Southern Urals

Abstract

Long-term monitoring of the abundance of the steppe polecat (Mustela eversmanii) in Chelyabinsk oblast is considered. The analysis of the abundance dynamics of Mustelidae was carried out on the basis of monitoring data using the method of winter accounting (WA) conducted annually. Over the past few years, the steppe polecat has not been registered during accounting work in the mountain taiga; i.e., its numbers are either extremely low, or it has disappeared completely. In forest–steppe territories for 12 years, from 2008 to 2020, the abundance of polecats decreased almost 90 times, from 3058 to 34 individuals. The data on the number of the main prey species of the steppe polecat, two species of ground squirrels (Spermophilus major and Spermophilus pygmaeus) and the groundhog (Marmota bobak), are presented. The hypothesis of the possible influence of the American mink on the numbers of the steppe polecat is considered.
