The effect of commercial cuttings on faunal associations in taiga ecosystems: A case study of small mammals in eastern Fennoscandia

Abstract

The general patterns of the effect of cuttings on the habitat structure, abundance, territorial distribution, and specific ecological features of 11 small mammalian species are analyzed based on long-term studies (1958–2013) covering the overall area of eastern Fennoscandia. The responses to concentrated cuttings common for most of the examined species include a decrease in total population size, transition to an arrhythmic population dynamics with drastic short-term rises and deep long depressions, formation of unstable mosaic spatial distribution, disturbances of the reproduction rates, and a decrease in reproduction intensity.
