First, briefly about history of lynxes in Naliboki Forest during several last decades. In the early and mid-1990’s, after the Soviet Union crash, perhaps in conditions of relatively weak nature protection, the majority of lynxes were poached in Naliboki Forest. In the 1980’s there was a dense lynx population in the terrain, but by the late 1990’s lynxes occurred sporadically there. In the early 2000’s lynxes began recolonizing Naliboki Forest. The severe snow conditions in the late winter and early spring of 2013 seemed to impact lynxes negatively, and the local lynx population number dropped from 35 to 22 the next winter. Indeed, during the spring of 2013, as far as we learned, local forestry workers and antler searchers found at least three lynx carcasses. All of them seemed to be subadults or kittens, because they looked relatively small.Continue reading “Rapid decline in the local population of lynx in Naliboki Forest, NW Belarus: density-dependent regulation or disease?”
Nowadays, the way of a researcher is overloaded with applying for projects and then producing numerous reports that can negatively affect the studies of wildlife. Such a situation is spread in the academic zone everywhere in the world. It wasn’t so hard for us a while ago, but during the last decade it started to be really too much, and that brought a feeling of wasting time in the academic zone. In effect, we quitted the zoological institute and university we worked for (in my case for 32 years), moved to our homestead in Naliboki Forest and continued the study on vertebrate predators (first of all, the wolf, lynx and badger) on our own.

The behavior and ecology of the Eurasian lynx during the snowless season, particularly from the second half of April till the end of October (hereafter the warm season), is still searchless, and several important questions of study on the species in this seasonal period are seemingly even unknown. The main hassle is that the prevailing research method of GSM GPS telemetry fails to investigate those questions. Basically this method only records coordinates and how active or passive the individual is. It looks like currently the single possible way to learn about the behavior and ecology during the warm season goes through much routine habitat inspection, art skills to read activity signs of lynxes in snowless period and smart extensive camera-trapping.Continue reading “Enigmatic warm-season behavior and ecology in Eurasian lynxes: pressing questions, hypotheses and results up-to-date”
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.
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).
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.
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.
