Mating in Eurasian lynxes

Mating in Eurasian lynxes and other questions in relation to that (such as pre-mating activity; life of kits, when their mothers go for mating; others) are quite poor investigated (e.g. Schmidt et al., 1997;  Schmidt, 1999; Jędrzejewski et al., 2002; Breitenmoser-Würsten et al., 2007; Samelius et al., 2012). The scarce information published on the question shows that these complicated mating-related actions in Eurasian lynxes are too simplified, while researchers mention about mating in lynxes. Let’s say there is evident gaps in the lynx-related literature on the species mating.

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.

Early denning behaviour and raising of pups after weaning in wolves

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.

Where do births and raising early days kittens in lynxes take place? When do lynxes give birth in Belarus?

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, during twenty years of searching for wolf dens in Paazierre Forest and Naliboki Forest in Belarus in April-June in 1997-2017 I have found more than one thousand of wolf dens (mostly without pups, former ones etc) under treefalls and other vegetation thickets (mainly young spruce ones), but only a few lynx denning sites (easily recognisable by presence of lynx hair) have been found under treefalls.

Changes in the wolf reproduction rate and packing pattern with the increase in the lynx population density

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.

Wolf breeding peculiarities

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”
