The materials on ecology of the lynx (Lynx lynx, 1758) in Yakutia

Lynx's distribution area in Yakutia is related to forest zone. In contrast to other Russia's regions lynx avoids human habitation proximity and practicallydoesn't approach to villages, horse breeders' camps or hunters' huts. The predator food baseis consisted ofmountain hare: 72,9% - in western areas, 75,9% -in central areas and 71,4%- in north-eastern areas of Yakutia (during the hare population peak). In southern, south-western and north-western areas this indicator is lower: 42,8, 38,6 and 36,3%respectively and the reason for that is because the mountain hare population in these areas is scanty, but on the other handdietary intake in these areas has a high percentage of the small ungulate occurrence (musk deer, roe deer) and birds. Four helminth species were detected in intestine: 2 cestodes and 2 nematodes. Total infection rate makes 95%. The lynx numbers are low and fluctuate too much throughout the years - from 700 to 1200 individuals.
