In June of 2018 there was post “Trends in the denning behaviour of the wolf and lynx in connection with the changes in the vertebrate community in Naliboki Forest (north-western Belarus)”, in which I described the changes in the denning behaviour of wolves and lynxes in connection with the population growth of the lynx, red deer, bison, and recovering of the badger population in the 2010s. It was shown that wolves with their prevailing of an open denning appeared in the hard situation to reproduce despite of the extra breeding efforts, first of all, with a pack multi-breeding.

In Naliboki Forest (north-western Belarus)there is Barsucha steading that was abandoned by locals seven years ago. For the last five years a male brown bear has been living here. There are about thirty power poles that brought electricity to the steading. The power poles were made from pine logs and deeply treated with tar (particularly by creosote). At least, 22 of these poles were regularly visited by the bear. The bear acted there by gnawing the poles and rubbing against them by different ways. Additionally the bear dug for the tar around the pole and rolled a lot on at the poles.
The variety of life styles of Eurasian lynxes in Belarus: a combination of the gained results and hypotheses
In Eurasian lynxes there are several age-sex categories, which are strikingly or markedly differed by their life styles. The data that leads us (Naust Eco Station & Wild Naliboki) to this conclusion originated from about 2300 km of snowtracking lynxes, multiannual study of lynxes with camera-traps (up to 70) and much other various research results. Among them the results of two lynx telemetry projects.
Climbing trees by Eurasian lynxes to emit territorial and mating calls in Belarus: pressing questions, knowledge up-to-date and difficulties to investigate this phenomenon
During the winter of 2017-2018 in Naliboki Forest we (Naust Eco Station and Wild Naliboki) have found that Eurasian lynxes climbed rather high pine trees to emit mating calls during the species mating season (Sidorovich et al., 2018). In total, during February and March 2018, we registered four such trees of the Scotch pine, on which adult male lynxes climbed for about 17-26 meters high. The density of the local lynx population was about 4-5 inds per 100 km2 i.e. about 80 per almost 2000 km2. We have evaluated that phenomenon of calling by lynxes from a tall tree top as a mating call, also taking into account that it was registered in the lynx mating season in Belarus (mid-February-early April).
Social contacts in Eurasian lynxes exclusive of between-mate relationships and mother-kittens behaviour
This post addresses the question of poorly known social contacts in the Eurasian lynxes exclusive of between-mate relationships and mother-kittens behaviour. In the book “Unknown Eurasian lynx Lynx lynx: New findings on the species ecology and behaviour” by Vadim Sidorovich, Jan Gouwy and Irina Rotenko (2019) we have stated that the species is not a solitary, but it is surprisingly social carnivore.
Peculiarity of usage of openings by lynxes
This post adverts the recent shift in the habitat-related lynx distribution for usage of openings and the lynx reaction to get back to forest in connection with the considerable changes in the wolf number in Naliboki Forest.

Enigma of lynx pee
During quite a lot of studies on the Eurasian lynx in Naliboki Forest and Paazierre Forest we realized that this species is still so poorly known (Sidorovich et al., 2019). Even a simple lynx pee hides several non-studied questions that were raised during investigation the species behavior. Several curious pee-related phenomena were registered that was already some achievement, but for every one still there is a pressing question how such a pee regime is possible on a morph-physiological level i.e. by means of which morph-physiological adaptations of the species. Maybe somebody, after reading the post, will try to investigate the lynx pee questions.
