Eurasian lynx are the third largest carnivores throughout most of their range. As such they have the ability to influence the population sizes, distribution, and behaviors of some prey species. Ungulates make up the majority of their diets and they can consume 1 to 2.5 kg of meat per day. In regions where game hunting isn't practiced, Eurasian lynx may play a role in controlling deer populations. They can kill from 10 to 40% of roe deer, red deer, and chamois populations annually. This is highly dependent on lynx density, ungulate density, and other causes of ungulate mortality. The greatest impact is usually seen in roe deer and chamois populations. Eurasian lynx are also affected by numerous internal and external parasites.
