Oleksandr Tiaganov, a collector, taxidermist, and researcher

An essay about the zoologist, who is noted as a collector of zoological museums of Ukraine (birds and small mammals) and of large samples of hedgehog diet (>1300). The researcher worked in a number of zoological centres in Kyiv and was associated with the zoological museums of the Ukrainian Academy of Agricultural Sciences (now NUBiP) and IZAN (NMNH). One of his most notable achievements was the analysis of hedgehog feeding, carried out not only by taxonomic groups of prey species, but also by their population, habitat and ecomorphological types. This allowed us to clearly define the species' trophic niche.
