| Popis: | The possibilities of using non-invasively sampled biological material to study the genetic diversity and status of the brown bear population in the European North of Russia are discussed. The effectiveness of sampling and preservation methods is evaluated. Fieldwork including non-invasive collection of biological material was carried out in the study area in spring, summer and autumn 2014–2016. The studied area covers the southeast of the Murmansk Region and the Republic of Karelia. 393 samples of bear feces were collected. We conducted DNA extraction from samples and genotyping with 8 microsatellite markers in the DNA laboratory of the NIBIO Svanhovd Research Station (Svanvik, Norway). 48 brown bear individuals were successfully identified. The influence of several factors (the preservation method, age of the collected sample, diet content and sun exposure) on the amplification success was studied. When we analyzed all factors together, only diet content had a significant effect on the amplification success (p |
