Since 1999 I have shifted own efforts on the study on the wolf Canis lupus population ecology. In 1996-1998 in Paazierre Forest (mainly in the Lovat terrain), the northern Belarus there were fulfilled studies on the wolf diet in relation to the dramatic changes in the preystock and on breeding in wolves. The research on the question of the species breeding had been continued there until 2005. However, since 2000 the main study area on wolves has been replaced in Naliboki Forest and its rural-forest surroundings. The species reproduction and breeding behaviour have become the main pressing questions of my zoological study.
By June 2017, 70 dens with pups were discovered altogether in Paazierre Forest and Naliboki Forest. Afterwards the majority of those pups were traced until the mid winter. While investigating denning by wolves, I paid much attention to the species denning behaviour. In 1997-2005 all the pups found were marked with a finger clipping that allowed to learn a lot of new things from the wolf life. In 2015-2017 we used intensive camera-trapping as an extra approach to investigate the wolf reproduction in Naliboki Forest.
Pack multi-breeding (16 cases), breeding of yearling females (2 cases) and hybridization with stray dogs (at least, 7 cases) were found, that makes this study quite unique. Wolf reproduction ecology, in particularly the species breeding, is still one of the two main studies I do.
Also, in 1999-2009 and in 2013-2014 in Naliboki Forest two or more wolf pack diets were estimated monthly. There were analysed diets of both free ranging wolves (adults or suadults) and parent-dependent pups. The first study period was characterized by unique prey supply situation, when all wolf-relevant prey species were common in Naliboki Forest; whereas in 2013-2014 the roe deer and wild boars got scarce there after the strong decline in the late winter of 2013.
In 2006-2008, I led the project in order to elaborate the national management plan for the wolf population in Belarus. Finally, it was achieved that wolves were partially protected in Belarus, at least, in the large enough reserves.
The results of the above-mentioned studies were partially published in the articles and two books (links below).
