From the post about the outstanding reproductive behaviour of one model wolf pack that is leading by quite old experienced female that we call as Torn Ear, perhaps, you already got to know that during this warm season i.e. in May-July 2020 we traced a very interesting breeding situation in this wolf group.

Concerning the wolf Canis lupus breeding in Europe and wider in Eurasia there is a widely spread belief that the species is strictly monogamous with a certain way of breeding and pack formation in family pattern (e.g. Bibikov D.I., 1985 and references therein; Jędrzejewska & Jędrzejewski, 1998).
Those beliefs suggested the three following theses: first, during breeding season, a wolf pack has merely one litter or there are no pups; second, usually a wolf pack consists of parent wolves and their pups of the current and previous biological years as a normal maximum; additionally, such a pack may subordinate some non-relative wolves; and third, usually offspring disperse from their maternal pack around mating season, in the second year of their life, when they are 20-22 months old.

Together with Irina Rotenko we recently published the second edition of the book on the wolf Canis lupus reproduction biology, which was based on the data gained in Belarus. There, we address the questions of the species mating, denning and raising of pups as well as mortality in wolf pups, which are still insufficiently investigated and full of contradicting hypotheses and knowledge. Therefore, the subtitle is “common beliefs versus reality”. However, the main thing for us in doing this book is to share the knowledge and skills we have gained on wolves in Belarus with wolf colleagues and amateurs.
In the second edition of the book we advanced all the former chapters basing on the results of the intensive study of wolf reproduction during spring-summer of 2018 and 2019 in Naliboki Forest. Also, we added one more chapter about the revealed trends in the denning behaviour of wolves in connection with the changes in the vertebrate community in Naliboki Forest.

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”
