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.

Wolf erasing off marking points of lynxes

In Naliboki Forest adult lynxes particularly males are known as killers of the vulnerable categories of wolves such as pups, lonely living subadults and heavily pregnant females (Sidorovich et al., 2019). Also, lynxes may be a valuable competitor for wolves in their exploiting of the roe deer and beaver populations.  Study on the interference of wolves and lynxes in Naliboki Forest suggested that wolves disagree with  presence of lynxes in the habitats, and they behave aggressively towards lynxes, too.  Lynxes feel safe in forest habitats, whereas they mainly avoid openings, when wolves are common in the habitats and where they may be killed by a wolf pack, because there are no trees to escape.

The role and origin of open ground spots for large carnivores, wild ungulates and other wildlife

In snowless period spots with open sand, peat or other ground types are outstanding elements in the habitat structure in  forested areas such as Belarus, and many mammal species tend to use them for territorial marking.  Among these mammal species first of all it may be mentioned red deer, bison, wolf and lynx.

Great interest in marking by lynxes from other mammals

This post addresses the  intriguing question of a great interest of wolves, red foxes and deer to lynx marking points, but there is no an opposite reaction of lynxes to marking by the above species. It is easy to realize, why red deer, roe deer and red foxes pay so much attention –  lynxes kill them often. Therefore, any information about lynx distribution and status (adult or young, sex, welfare etc.) are important for these victim species. The same is for wolves. Adult lynxes not rarely kill wolves  from vulnerable categories such as pups, heavily pregnant females, just small individuals (Sidorovich et al., 2018). However why do lynxes pay a minimal attention to marking by deer and even by wolves?

Abandoned log piles as habitat spots that are important for lynx families

Quite often clearcuts in Naliboki Forest are full of logging remains. Moreover, sometimes loggers forget one or several piles of logs and they stay there for decades. It is always like a gift for lynxes, particularly the species families. The main  benefit of lynx family is that mother may leave small kittens there, and they will be safe alone in the emptiness under the logs, when the mother goes for hunting. It is especially essential, because  lynxes frequently use a long-lasting hunting from ambuscades, so, kittens need to wait for the mother quite long.

Dramatic situation in the beaver population in Naliboki Forest in relation to hotter and drier summers nowadays

Till the 1960s  Naliboki Forest, which is situated in the north-western Belarus, was a greatly swamped terrain, where on the area about two thousands km2 swamps of various types and sizes were interspersed with dry land forests the terrain-wide. Open grassy marshes constituted about 19%  of the terrain. Approximately a third part of the forest habitats that covered about 76% of the area were swamped too (Sidorovich, 2016). Such a swamped forest was either in kinds of black alder and downy birch mixture (with prevalence of one of the species) or that was raised bogs with suppressed or normal pines.
