Within the analysis of vertebrate predator-prey community we carried out the population studies on the badger Meles meles and raccoon dog Nyctereutes procyonoides with implication for the strong decline in badgers even in seminatural terrains in Belarus. Continue reading “What is the cause of the badger population decline in Belarus? “
We have found a great difference in hunting styles of lynxes between the warm and cold seasons. In the cold season, particularly during the snow period lynxes hunt mostly by walking i.e. patrolling prey-rich habitats and suddenly attacking prey. In the warm season lynxes mainly wait for prey from a hide over prey pathway. Such waiting usually lasts about ten and more hours. Continue reading “Difference in hunting styles of lynxes between the warm and cold season with implication for the home range structure”
The common belief of the lynx-related zoologists is that parturition in lynxes takes place in a thicket somewhere under treefall. Sometimes, it really happens. However, for more than twenty years of searching for wolf dens in Paazierre Forest and Naliboki Forest in Belarus in April-June I have found almost two thousand of wolf dens under treefalls (mostly without pups, former ones etc), but only a few lynx denning sites (easily recognisable by presence of lynx hair) have been found under treefalls.

Together with Irina Rotenko I started preparing a book about wolves in Belarus. There, we will address the questions of the species reproduction biology that are still insufficiently investigated and full of contradicting hypotheses and knowledge. However, the main thing for us in doing this book is that being interested in studying these hidden part of wolf life, we would like to share the knowledge and skills we have gained on wolves in Belarus with wolf colleagues and amateurs. Continue reading “Plans for a book on the wolf reproduction biology”
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. Continue reading “Changes in the wolf reproduction rate and packing pattern with the increase in the lynx population density”
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”
For more than thirty years, till 2016 I had worked for the Institute of Zoology of the National Academy of Science of Belarus. But with time I started noticing that my working time was more and more wasted on the continuous applying for projects, reporting and very time-consuming presenting of the results in scientific journals. There was not enough time for the study itself. But if even a quite successful zoologist neglects this applying-reporting-presenting chain, soon he will appear without a financial support. So it seems the only way for a reseracher to be employed as a zoologist with some financial resources is to stay at a computer screen. Such a system in zoology seems to act all around the world, when an experienced zoologist should spend the main working time like that. I got convinced that, at least, it is true for zoology of vertebrate animals, the field I have worked in for more than 30 years since 1984.
