Geographic Range
Eurasian lynx are one of the most widely distributed cat species. Their range once
extended throughout Russia, Central Asia, and Europe. Today they occupy a range extending
from western Europe through the Russian boreal forests and to the Tibetan Plateau
and Central Asia. Eurasian lynx distribution is greatly limited by the presence of
humans and their activities. They are less frequent in areas with many settlements,
roads, railways, and highways as these increase fatality and injury. Also, because
they tend to shy away from open areas, lynx distribution is dependent on regions with
high forest cover as well as forest connectivity. Deforestation in regions throughout
parts of their range limits forest connectivity and hindering dispersal of
Lynx lynx
throughout Europe and Asia.

Habitat
Eurasian lynx live in a variety of habitats. In Europe and Siberia they inhabit forested
areas with dense ungulate populations. In Central Asia they are found in open, thinly
wooded areas and rocky hills and mountains in desert regions. They are also found
in rocky areas and thick woodlands throughout the northern slopes of the Himalayas.

Physical Description
Of the four
lynx
species, Eurasian lynx are the largest. They are also one of the largest predators
in Europe, third to only
brown bears
and
grey wolves
. Their size ranges from 18 to 36 kg, body length is 70 to 130 cm and shoulder height
is 60 to 65 cm. Sexual dimorphism is present, with males being larger and more robust.
The coat is varied in grey, rusty, or yellow fur. There are three main coat patterns:
spotted, striped, and solid. Among those that are spotted, the pattern ranges among
large spots, small spots, and rosettes. Patterns vary widely within and among regions.
The belly, the front of the neck, the inside of the limbs, and the ears are whitish.
The tail is short, with a solid black tip. Eurasian lynx have long legs, sharp retractable
claws, a round face, and triangular ears. Characteristic features of Eurasian lynx
are black tufts at the tips of the ears and a prominently flared facial ruff. The
paws are large and fur-covered, which helps them to navigate in deep snow.
The skull of Eurasian lynx has characteristics typical of other felids : a short rostrum,
rounded top, small M1, and lack of M2. They have features shared by other
carnivorans
as well: large, well-developed canines, and well-developed carnassial teeth. Unlike
most other felids, Eurasian lynx have lost one upper premolar giving them the dental
formula: I3/3 C1/1 P2/2 M1/1.
- Other Physical Features
- endothermic
- homoiothermic
- bilateral symmetry
- polymorphic
- Sexual Dimorphism
- male larger
Reproduction
Eurasian lynx mating season takes place from February to April of each year. Each
female is fertile only about three days during this time. Once a male and receptive
female encounter each other, they follow each other for days, copulating many times
a day. Once the female is no longer in estrus, the male will leave to find another
mate. Females have only one mate per season.
- Mating System
- polygynous
Gestation lasts 67 to 74 days, with females giving birth in May. Breeding interval
varies, depending on success of previous season. Females without a litter will breed
every year, females with a litter will breed about every 3 years. Typically 2 to 3
cubs comprise a litter, although litter size can range from 1 to 5 kittens. Newborn
cubs weigh 300 to 350g and are dependent on their mother for food and protection.
They are weaned at 4 months and become independent at around 10 months. Females become
sexually mature at 2 years of age and can remain so up to 14 years of age, whereas
males mature at 3 years of age and can reproduce up to age 17.
- Key Reproductive Features
- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- induced ovulation
- viviparous
Females find a safe den space for their kittens, as in a hollow log or crevice. Females
nurse and protect their young until independence. Once the cubs are old enough to
travel they accompany the mother on hunting trips to learn how to hunt for themselves.
Males do not contribute to the care of offspring.

Lifespan/Longevity
Eurasian lynx can survive up to 17 years in the wild and 24 years in captivity. Juvenile
mortality rate is high.
Behavior
As solitary creatures, the only long lasting relationship formed in Eurasian lynx
is between mother and cubs. They are most active during early morning and the evening.
When they are not active, they spend their time resting under the cover of thick brush,
tall grasses, or in trees. They are mainly terrestrial but are adept at climbing and
swimming.
- Key Behaviors
- terricolous
- diurnal
- nocturnal
- crepuscular
- motile
- sedentary
- solitary
- territorial
Home Range
Individual home ranges can range from 25 to 2800 square kilometers, depending on habitat,
density, and prey availability. Female territories range from 100 to 200 square kilometers,
males occupy ranges of 240 to 280 square kilometers. Female choice of territory is
based on prey and habit resources needed to raise offspring. They occupy smaller ranges
when they are caring for a litter. Home ranges may overlap greatly with their daughters
and slightly with other females. Males choose territories to give them ample access
to females and their home ranges will sometimes overlap with 1 or 2 females and her
cubs. Home ranges of both sexes tend to be inversely proportional to prey availability,
increasing as prey population declines. Ranges are also larger when area of preferred
habitat is greater.
Communication and Perception
Little is known about communication among Eurasian lynx. Their vocalizations are low
and not often heard. They have keen eyesight and hearing, mainly used to locate prey
and potential mates. Males and females mark their home territories with gland secretions
and urine.
- Other Communication Modes
- scent marks
Food Habits
Like other members of the family
Felidae
, Eurasian lynx are strict carnivores, consuming only meat. Other
Lynx
species are specialized
rabbit and hare
hunters. Eurasian lynx prey primarily on
ungulates
. Small ungulates such as roe deer (
Capreolus capreolus
), musk deer (
g. Moschus
species) and chamois (
Rupicapra rupicapra
) comprise most of their diet, but they have been known to prey on ungulates as large
as
elk
and
caribou
in winter due to the prey’s vulnerability in deep snow. Eurasian lynx also supplement
their diet with
red foxes
,
rabbits and hares
,
rodents
and birds. They kill prey up to 3 to 4 times their size and consume 1 to 2 kg of
meat per day. Eurasian lynx stalk their prey from the cover of thick vegetation, using
stealth to get close without being seen. They then pounce on prey, delivering a fatal
bite to the neck or biting down on the snout until the animal suffocates. The kill
is then taken to thick cover or fallen logs to be eaten in privacy. Prey that is not
eaten right away is cached to be consumed later.
Eurasian lynx occur sympatrically with three other large predators throughout most
of their range:
grey wolves
,
brown bears
, and
wolverines
. Brown bears are mainly omnivorous and don't compete strongly with lynx for prey.
Where wolves and and Eurasian lynx co-occur, they generally coexist peacefully with
neither of the two showing avoidance or attraction. This has been attributed to differences
in primary prey selection and hunting styles.
Grey wolves
are larger than Eurasian lynx and primarily hunt
red deer
, while Eurasian lynx focus on
roe deer
and smaller ungulates. Eurasian lynx are solitary hunters, concealing themselves
in thick vegetation, fallen logs, and snow to ambush prey. Conversely,
grey wolves
are pack hunters and found in a wider variety of habitats. Competition between these
species may occur in areas where
roe deer
,
red deer
, or other ungulate prey is scarce. This may cause changes in hunting behavior and
has contributed to sporadic intraguild predation of Eurasian lynx by
grey wolves
.
- Primary Diet
-
carnivore
- eats terrestrial vertebrates
- Animal Foods
- birds
- mammals
- Foraging Behavior
- stores or caches food
Predation
Eurasian lynx have no natural predators, but there have been cases of intermittent killings by tigers, wolves, and wolverines.

- cryptic
Ecosystem Roles
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.
Economic Importance for Humans: Positive
Eurasian lynx came close to being endangered in the early 1900's as a result of hunting
for fur. Currently, commercial hunting is illegal in all countries except Russia and
Eurasian lynx are protected in Afghanistan, where all hunting and trading is illegal.
However, illegal fur trades occur in some countries. In regions where game hunting
isn't practiced, Eurasian lynx may play a role in controlling deer populations.
- Positive Impacts
- body parts are source of valuable material
Economic Importance for Humans: Negative
Throughout most of their range, Eurasian lynx are the third largest predators. They
typically do not attack humans unless injured, trapped, or ill. Humans sometimes complain
that Eurasian lynx reduce game abundance and kill livestock and domestic animals.
In most European countries programs have been set up for farmers and herders to compensate
them for losses.
Conservation Status
Habitat loss due to deforestation, prey loss due to game hunting, and illegal hunting
and trapping for the fur trade are the main threats to
Lynx lynx
. Commercial hunting is illegal in all countries except Russia and Eurasian lynx are
protected in Afghanistan, where all hunting and trading is illegal. In the 1960’s
and 70’s, some Eurasian lynx were re-introduced into Germany, France, Austria, and
Switzerland. These populations have been successful in some areas.
Other Comments
There are many described subspecies of lynx, although there is no agreed upon subspecies classification. Subspecies include:
Lynx lynx lynx , found in Scandinavia, eastern Europe, and western Siberia.
Lynx lynx carpathicus , found in the Carpathian Mountains and central Europe.
Lynx lynx martinoi , found in the Balkans.
Lynx lynx dinniki , found in the Caucasus.
Lynx lynx wardi , found in the Altai mountains.
Lynx lynx wrangeli , found in eastern Siberia.
Lynx lynx isabellinus , found in central Asia.
Lynx lynx kozlovi , found in Central Siberia.
Lynx lynx stroganovi
, found in the Amur region.
The name lynx is thought to stem from Lynceus in Greek mythology who was said to be so sharp sighted that he could see through the earth. This is in reference to the keen eyesight of lynxex. Lynx are the national animals of Romania and Macedonia.

-
Coniferous or boreal forest, located in a band across northern North America, Europe, and Asia. This terrestrial biome also occurs at high elevations. Long, cold winters and short, wet summers. Few species of trees are present; these are primarily conifers that grow in dense stands with little undergrowth. Some deciduous trees also may be present.
- desert or dunes
-
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.

- polymorphic
-
"many forms." A species is polymorphic if its individuals can be divided into two or more easily recognized groups, based on structure, color, or other similar characteristics. The term only applies when the distinct groups can be found in the same area; graded or clinal variation throughout the range of a species (e.g. a north-to-south decrease in size) is not polymorphism. Polymorphic characteristics may be inherited because the differences have a genetic basis, or they may be the result of environmental influences. We do not consider sexual differences (i.e. sexual dimorphism), seasonal changes (e.g. change in fur color), or age-related changes to be polymorphic. Polymorphism in a local population can be an adaptation to prevent density-dependent predation, where predators preferentially prey on the most common morph.
