Diversity of alien mammal species in different regions of Russia

Abstract

A map of diversity of alien mammal species in Russia has been created. The map shows that, in the second half of the 20th century, the mammal fauna in the majority of Russian regions changed as result of either deliberate or accidental delivery of different mammal species by humans and self broadening of their ranges. Among regions, the maximum number of alien species is noted in the south of the European part of Russia (27 species); Kamchatka ranks second (10 species).

Prevalence of Toxoplasma gondii infection among small mammals in Tatarstan, Russian Federation

“…In the classification of small mammal species, small mammal species were classified as alien ( A. agrarius, A. uralensis, A. flavicollis, Mi. arvalis ) and non-alien ( M. glareolus, S. araneus, D. nitedula ) 13 . The forward selection procedure generated a model that included area, vegetation and the type of small mammal species that best fitted the data (Model 3, Supplementary Table S2 ).…”

“…Multivariate logistic regression was performed using the R statistical software package (version 3.6.3) 28 to assess the trapping point area (urban or rural), vegetation (forest or field), small mammal species type (alien or non-alien species), age (0–2 months-old juveniles, 3–6 months-old adults or ≧ 6 months old), sex (male or female) and distance from trapping points to the nearest human settlements as risk factors for PCR positivity. According to previous reports 2 , 13 , 16 – 18 , four species, Mi. arvalis , A. flavicollis , A. agrarius , A. uralensis , and three species, My.…”

Beaver trapping in Russia and Belarus and problems of resources management

“…It is not productive to embrace the extreme position of describing the beaver as "invasive, alien species, most dangerous to natural ecosystems" (Khlyap et al, 2011). The Castoridae has a rich and diverse evolutionary history including during the Miocene and Pliocene when the number of known beaver genera reached 30 (Korth, 2001).…”
