Recently published book on the wolf reproduction biology

Together with Irina Rotenko we published 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.

3.5. Estimation of wolf fertility parameters
3.6. Investigation of wolf pack composition
3.7. Study on the interference between wolves and lynxes
3.8. Gathering of scats of wolf pups and their parents, analysis of the scats in order to estimate the pup and parent diets
3.9. Determination of wolf age

This scientific monograph gives a detailed information about reproduction biology in the grey wolf Canis lupus in Belarus. This topic includes the wolf breeding (mating and denning) behavior, fertility of the species and mortality of its pups. The initial material was not collected occasionally from wolf hunters and wolf pup searchers, but mainly gained by authors first-hand according to a well-set research design and long-term. By analyzing the gathered data, we became convinced that in the wolf reproduction biology there are more exceptions than rules. Therefore, the standard patterns of reproduction biology in wolves that are wide-spread in the published literature about the species we call as common beliefs that are given versus the wolf reality that we have found in Belarus. Concerning the non-standard features in the wolf reproduction biology, we revealed that multiple breeding in wolf pack is a common phenomenon, breeding of yearling females and wolf-dog hybridization were found to be irrespective the food base and strongly depending on the species population density i.e. they are reproduction regulations. Wolf pup mortality was investigated and the crucial role of deliberate predation of lynxes on wolf pups was revealed.

      1. Dear Vadim, would love to get your book as fellow wolf researcher with a similar research approach. How can I purchase a hard copy?

        And I would be interested in visiting to get out into wolf country.

        Best regards,


  1. Dear Vadim, dear Irina,

    With great pleasure I have just read your latest work about the wolf in Belarus.
    A comprehensive summary and scientific supplement of your research about the reproductive biology of the wolf in Belarus.
    Written by two exceptionally passionate field biologists.
    Based on decades of practical experience and really extraordinary field research.
    Highly recommended for all scientists and laymen interested in this topic.

    I am looking forward to my visit to the Naliboki forest in May and I would be glad to get a printed edition to take home with me.

    Best regards

  2. Dear Vadim, I do not know whether you remember me from otter conference in Pavia. I have a question, whether there are any reliable cases of wolf attacks on human from Belorussia from last 20 years? The wolves are returning to the Czech Rep. and we have a tough discussion regarding this issue, with allegedly cases being reported from Belorussia. Thanks a lot, Tereza Minarikova, ALKA Wildlife

    1. no attacks of humans from healthy wolves so far since 1950th, some cases when rabid wolves bit a few people but not every year (nobody was killed or heavily wounded)
