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.

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.

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”

Investigation on the lynx population biology (general information)

Since the early 2000s I have paid more and more research attention to the lynx Lynx lynx. At that time there were not much known about the species in Belarus. Thus for the beginning I raised only regionally important questions of the lynx ecology, which had been investigated in other parts of the species range, but seemingly they are not entirely answered still somewhere as well as in Belarus. Among  the basic ecological questions I considered the most common ones such as the  species population number and habitat carrying capacity, distribution of lynxes in its between-year and seasonal changes, home range and its structure,  prey supply and  foraging, diet in its between-year and seasonal changes, lynx predation impact on the prey populations, reproduction rate and mortality causes.

Investigation of the wolf population biology (general information)

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.
