Abstract

Forty-five-year-long observations of variations in the musk deer abundance in the Ussurisky Nature Reserve are summarized. An analysis of winter route censuses (WRC) has made it possible to assume that these variations are related to the emergence of a new predator, the sable. The decrease in the musk deer abundance in the reserve occurred simultaneously with an increase in the sable abundance and a decrease in abundance of alternative food supplies for medium-sized and small predators. From the early 2000s to the present, the musk deer abundance in the reserve has remained at a level of only “presence” of the species in the fauna.

乌苏里自然保护区麝Moschus moschiferus L.(鲸足目，麝科)数量减少的可能原因

摘要总结了乌苏里江自然保护区45年来麝丰度变化的观测结果。对冬季路线普查(WRC)的分析使人们有可能假设这些变化与一种新的捕食者——黑貂的出现有关。保护区麝丰度的减少与貂丰度的增加和中小型食肉动物替代食物供应丰度的减少同时发生。从21世纪初到现在，保护区的麝丰度一直保持在动物群中只有“存在”的水平。

期刊介绍： Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
