Gradually, we have become quite advanced in investigating these hidden traits of the species, having already found more than twenty lynx lairs. Step by step, we are moving toward publishing a comprehensive analysis of the concealed features of Eurasian lynx reproduction.

Scientific book “Behaviour and ecology of the Eurasian lynx” has been published

This scientific book gives the results of the long-term studies on the Eurasian lynx Lynx lynx in Belarus, mainly in Naliboki Forest and Paazierre Forest. Population structure, breeding, diet and prey supply as well as the variety of behavioural traits were considered. Among behavioural questions there were investigated sociality, hunting modes, mating and denning behaviour, territorial marking, sheltering and interspecific interference. The monograph presents not only the regional aspects of lynx biology, but also includes many new findings for the Eurasian lynx overall.
