I would like to share our knowledge on the early denning behaviour and raising pups after weaning in wolves basing on the information that was gained in Belarus mostly in Naliboki Forest and Paazierre Forest.
The information is divided into two items: the first item is early denning behaviour in wolves; and the second one is raising of pups after weaning.

aReading literature and talking with wolf and lynx researchers, it becomes evident that interference between the two species is actually poorly studied. Some mammalogists tend to assume that wolves suppress the lynx population. Some even suggest details of the aggressive behaviour of wolves towards lynxes: strong wolf packs attack lynx family groups and kill kits during lynx mating season when the kits stay alone or disperse. Seemingly, such stories are only speculative beliefs and ideas. Continue reading “Findings on the interference between wolves and lynxes “
Concerning competition between wolves and lynxes in Belarus, it is worthwhile to compare the situation in the local wolf population in Naliboki Forest in 2008-2012 (when there were half as many lynxes as there are now) and in 2015-2017 (when there were about 50 and even more lynxes). Both wolves and lynxes were more or less protected in Naliboki Forest in the 2000s.

In Europe and wider in Eurasia between wolf researchers and in the circle of other wolf-related people (e.g. hunters specialising in killing wolves, wolf pup searches) there is a widely spread belief on wolf reproduction that wolves are strictly monogamous species with a certain way of breeding and family pattern of pack formation. Actually, in my study in Belarus since the late 1990s there have been found so many abnormalities in those, that I start to think about what actually prevails in the wolf reproduction and packing: the “rules” or “exceptions”. Such “abnormalities” occurring too often are a very interesting phenomenon and they need to be further investigated. Continue reading “Wolf breeding peculiarities”
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. Continue reading “Investigation of the wolf population biology (general information)”
Since my childhood I have been very interested in tracks of mammals and in the entire variety of activity signs of mammals and birds on the whole. Within this my passion I tried to push forward not only identifying of mammal activity signs, but their usage in track-based research methods on population ecology as well as to reconstruct correctly the respective behavior of mammals from their activity signs.

In the period of 1993-2010 I led the Vertebrate Predation Research Group in the same research Institute of zoology, National Academy of Sciences of Belarus. The group consisted of 3-12 colleagues (including PhD-students and Diploma-students) and was aimed to investigate vertebrate predators, mainly carnivores, but also owls, diurnal raptors and snakes. The studies took place in Paazierre Forest (the northern part of Belarus) and Naliboki Forest (the central-western part of Belarus), i.e. semi-natural terrains with transitional mixed forest within the European Forest zone.
