Tour to Neocene
|
||||||||||||
The changes occuring in the Neocaenic world, had affected practically
all areas of the Earth. Increase of air humidity had resulted to that areas,
earlier had being deserts, now turn to places rich in vegetation. Such areas
became in Neocene plains of Central Asia - former deserts Gobi, Takla Makan,
Kara Kum, Kizil-Kum. Numerous lakes and short rivers now dot these former deserts,
transforming them to bush savannas. In winter instead of keen frosts and plentiful
snowfall here there are rains and only small cold snap. Only in the coldest
winter months light frosts keeping of some days are possible. But spring, summer
and autumn are remarkable by heat and moderate humidity. Such climate promotes
prosperity of life in these places.
The vegetation of plains of Gobi represents extensive bush thickets. Bushes
of sea-buckthorn (Hippophae), лоха (Elaeagnus), raspberry and blackberry bushes
(Rubus), steppe species of cherry (Cerasus), breeding by root shoots, cover
wide areas near rivers and lakes. Far from water bushes are replaced by high
grasses, and on boggy places willows, canes, reed mace and sedges expand richly.
And this world is full of animals.
Now it is the end of summer – the time of ripening of berries and seeds. Among
grass it is possible to notice spotty red backs of small mammals, keeping by
group. They are rodents - bushgophers, descendants of suslics. When deserts
and grassy plains began to recede under an impact of bushes, the part of plain
species had adapted to the inhabiting in the new environment. Suslics became
one of such successfully adapted species. Now they do not dig long holes, and
build in bush thickets drays of grass and prickly branches. Bushgophers are
social animals, settling by big colonies - "towns". Places of such
settlements are easy for noticing - grass near them is more shortly and thicker
because these small mammals constantly eat up it. From fodder area of the colony
pathes to other sources of food, to berry bushes, lead. Bushgophers willingly
swarm up bushes, eating juicy berries. When at the end of summer berries ripen,
bushgophers are completely passing to this tasty seasonal forage. But thus small
mammals visit thickets of graminoids and gather ripe seeds. Their small mammals
will carry in cheek pouches to their drays and will hide in special storehouse
chamber. The pair of bushgophers occupying this dray, will feed by this grain
during the winter when other forages will be not so accessible. On a kernel
filling cheek pouches, bushgophers are fed with young grass. However they should
be on alert: in these places the predator, to which small rodents rather to
taste had appeared.
From bush thickets the huge sandy-yellow lizard - the running monitor - is shown.
It seems huge, more reminding the lean crocodile, than the lizard. On the head
behind eyes of the lizard few large scales stick up by semicircle, forming something
like "crown" - such ornament mature males have on their heads. The
sand coloring shows that the big lizard had crawled from stony uplands, and
not long time ago. While the big lizard is too swept up on the background of
greenery, but in some days this colouring will be changed to cryptic striped
one and then the reptile can expect for more successful hunting.
The running monitor lifts its head up above grass and some times tries air by
tongue like snake. Feelings have not brought the reptile - nearby bushgophers
eat grass. The big lizard is hungry, therefore it begins hunting immediately.
Being hidden in grass, the monitor lizard starts to creep to nothing suspecting
rodents eating rich grass. From time to time it tries air by tongue, as if not
trusting its own feelings. But when to desired catch only a little more, than
one successful throw was, hunting is broken: from bush one of bushgophers jumps
out loudly cheeping. It was fed with berries, and from height had noticed light
yellow giant on the green grass background. Immediately all bushgophers begin
movement: they run away by high jumps, having pulled up and having fluffed up
tails. White stain of the inner side of the tail are an alarm signal.
Trying to prey the bushgopher, the running monitor rushed after them: it jumps
up on hinder legs, and rushes for skipping rodents, as if a dinosaur. The narrow
head of the reptile clicks by sharp teeth literally near a paw of one bushgopher,
but the rodent nevertheless slips away from a predator at last moment. The chance
is missed.
The monitor lizard can not pursue catch at the long distance - its metabolism
does not promote it. Therefore the reptile runs absolutely small distance, pursuing
bushgophers, and then stops. The monitor lizard pants: it had given all the
best in this throw. Even if now the bushgopher will approach closer, than it
is necessary for a successful throw, the lizard can not catch it - rest is needed
for this purpose. And the monitor lizard hides in bushes, hungry and tired.
Not only to bushgophers the nature gives plentiful entertainment: among bushes
larger animals, huge saigochenias, hoofed herbivore mammals are fed also. Due
to three-meter growth and long proboscis these animals became unique animals
in these places, eating foliage of trees and large bushes. At the end of summer
they willingly eat berries of steppe cherry and sea-buckthorn. Seeds of these
plants are carried away with manure of the saigochenia, therefore both species
of bushes profit from such cooperation.
But also to other species there is an advantage of saigochenia feeding: bushgophers
willingly eat the overripe berries falling on the ground when the giant turns
in to itself branches of a plant using the proboscis. But bushgophers should
be cautious and jump aside in time, when the saigochenia shifts from one foot
to the other. But ripe berries and full safety from predators become the award
to cautious small mammals. The monitor lizard will not dare to hunt, when bushgophers
are hidden in grass at legs of the giant saigochenia, otherwise it can expect
sound impacts of hoofs of these giants. Saigochenias do not pay attention to
the bushgophers scurrying under their legs, but the monitor lizard can be dangerous
to the calf, therefore the saigochenia mother always keeps an eye on the monitor
lizard having appeared nearby and tries to drive it off.
On backs of saigochenias berryfinches, tiny birds with striped back and red
belly, fall. Usually they eat vegetative food, but the saigochenia’s back for
them is the set table. Finches peck parasites sitting in wool of the saigochenia,
relieving the monotony in the menu. Such procedure almost does not bring anxiety
to saigochenias. However when the finch sits on the head of the saigochenia
female and starts to handle by thick beak in dangerous affinity from an eye
of the animal, the saigochenia shakes a head and banishes the importunate doctor.
Finches swarm up legs and neck of the saigochenia, but especially frequently
they are late in long mane of males which covers the basis of neck, shoulders
and chest of animal. One of such long-manned males feeds near coast of lake,
browsing leaves of young willows. He does not pay attention to birds scurrying
on his body. Now at the saigochenia the rut begins, and the male is anxious
mainly with search of females. Usually males are solitaries, and females keep
by small groups –it is more easy to protect cubs this way. And only during pairing
males join groups of females, within several days frequently coupling with them
and driving away competitors. The breeding season passes very roughly: the organism
of the male is overflown with hormones. They stimulate enlarging of rich mane
and aggressive behavior in relation to other males. And to increase the hormonal
level, males resort to the help of natural stimulators. Near reservoirs on enough
damp nutritious ground one plant grows, desired for males of the saigochenia
- the bush lily. In the beginning of summer it flowers by clusters of light
white flowers, and in second half of summer the elevated part of plant starts
to dry out. In ground the fragile friable bulb stays up to which saigochenia
males in breeding season are especially having an urge. Juicy bulb scales of
this plant are rich in stimulating substances, therefore males try to find them,
sniffing the ground by long proboscis. Having sensed a desired smell, the male
starts to dig ground by hoof. Soon from the ground bulb appears which falls
to scales because of careless hoof impact. Simultaneously from the damaged tissues
of plant sharply smelling substance starts to exude. The saigochenia male greedy
devours few bulb scales of lily, and then lies down and starts to wallow on
the dug out ground, pulling by long legs in air. The odorous substance from
the crushed lily is absorbed in his wool, giving to it a characteristic pungent
smell. Also the sexually active saigochenia male likes to wallow on other odorous
plants like mint or sagebrush. Dilligently "having perfumed", the
giant goes to searches of females. Thus he utters the sounds involving females
ready to pairing: the male blows out the proboscis and nasally blows.
Four females by group go down to the watering place on the bank of shallow rivulet.
While three of them drink, the fourth one is on the alert: she looks around
and listens, trying to sense possible danger in good time. Then one of the females
had quenched its thirst replaces her on guard. Animals drink slowly, rising
heads after several drinks. The easy breeze wafts to them a smell causing at
animals the big interest: it is the smell of the male amplified with smell of
grasses, in which that one had wallowed. One of females is ready to pairing,
and she utters thin peep through the proboscis. And it is heard: on an opposite
bank of the stream from bushes the male appears. It does not smell females:
the wind blows from him. Therefore the giant passes shallow stream wade and
carefully sniffs at all females, being late on one ready to pairing. The male
sniffs serially at heads, shoulders and tails of females, and then blows by
proboscis and starts to accompany with this group.
Some days passed. Saigochenias have a rest in thickets of sea-buckthorn, eating
berries. All four females are already pregnant, but the male still does not
leave them. He protects the harem and territory from contenders who regularly
appear on borders of his possession. It is visible, that the male is appreciably
exhausted: bad feed has an effect. During a rut males can not eat and not sleep
till some days in succession, thus they strongly exhaust themselves.
On border of his possession other saigochenia male is shown: young, not completely
matured. His mane is short and thin, and he keeps still very uncertainly, constantly
smelling around. The owner of territory and harem leaves to him towards. It
is visible, that it was not sweetly to him in breeding season: he had become
emaciated, and his body is covered with bruises and traces of stings. Contenders
appreciately look against each other, and then simultaneously rear and beat
each other by forward legs. The mane softens impacts, but it is visible, that
more mature male loses to young one. The young male comes, beats legs and eventually
fells the contender on the ground and bites him. Now he is a lawful owner of
harem. But... when the youth approaches to females, proud of unexpectedly easy
victory, those practically do not pay attention to him. The youth blows by proboscis,
rears before females, but it does not make impression on them. Females had already
started to bear cubs and they are not interested by males. When the newly appeared
winner approaches to one of females, she jumps up, having blowing out the proboscis,
and beats the male sideways by the bent forward leg. Impact not painful, but
strong - the male understands, that here he has nothing to wait, and leaves
females.
The rut at bushgophers will start later - in early spring. And to summer they
already will have cubs. If they will be lucky to survive, to autumn they become
independent.
When saigochenias find out relationship, noisily running one after another,
or colliding by chests, from under their legs scared bushgophers jump out. Small
mammals run up and hide in bushes where their settlements are located. The shelter
of the bushgopher is hidden in the thicket of branches and its entrance in addition
is strengthen with sticks of prickly bushes, gnawed out and carried here specially
for protection against uninvited visitors. The short wattled corridor, frequently
common for several drays, ends by the living chamber and extensive "pantry"
where seeds of grasses for winter are poured. In each hole pair of small mammals
and their posterity before maturity live. Animals constantly repair shelter,
change litter and fill up forage stocks. While adult animals are occupied with
home efforts, young bushgophers are eaten off preparing to forthcoming winter.
They are more mobile than adults, and they can get with dexterity on bushes
behind berries. Comfortably having arranged on the firm branch, one young bushgopher,
without spots on the back, feasts on hot sunny place. Taking from cheek pockets
the gathered berries, small mammal eats them. But it does not lose vigilance:
danger can appear from everywhere. And soon the bushgopher notices in bushes
at distant edge of glade the suspicious moving. For one second from grass the
long narrow head had appeared, "threw" by tongue and had hidden again.
The running monitor had going to hunt again. Warning chirp is listening and
all bushgophers hide in bushes. However the monitor lizard is not so silly and
monotonous in methods of hunting too. Its narrow head on the long neck allows
the reptile to survey drays of bushgophers, what are located at edge of the
"town". The reptile slowly approaches to bushes where terror-stricken
bushgophers had stood in shelters. The monitor lizard had already replaced colouring:
now its body is decorated by cross strips, and the body is colored in grey and
green.
The narrow head on flexible long neck starts to survey one dwelling of bushgophers
before another. Some drays appeared empty, one more appears too deep. But the
body of monitor lizard has climbed in bush little bit more deeply, has stood
for one second, and then jerky has left back. In teeth of monitor lizard the
lifeless body of the young bushgopher dangles. Having thrown it in air, the
monitor lizard catches prey more conveniently and has swallowed it. Then the
reptile has slowly left a colony of small mammals, having gone to get warm on
the sun.
Finches observed at this scene from tops of bushes. They practically do not
afraid of monitor lizards: they fly quickly. But the nestlings had dropped out
of nests or careless badly flying fledglings frequently became prey of huge
reptiles. Now survived birds can be quiet: the monitor lizard precisely will
not catch them, while they are healthy. Finches scurry in bush thickets, eating
berries - the basic forage at the end of summer and the beginning of an autumn.
Young birds, which can be distinguished from adults on less bright feathering,
are already fed independently. But they should be cautious: the hunter also
traps them. When the young berryfinch pecks berries, four large shining berries
which are sticking up on fruit spurs among greenery involve its attention. The
inexperienced bird has got in trap: it approaches to the death closely and closely.
And at that moment when the finch has tried to peck up one of these berries,
ruthless spiny legs have gone into its body. The finch has fallen a victim to
large insect - the cherry soothsayer. Four "cherries" appear only
bladders filled with air on bends of its walking legs. Powerful forward legs
of the soothsayer keep fluttering finch, and mandibles of insect put stings
quickly killing catch. When the catch stops resisting, the huge insect creeps
to the convenient branch where starts to tear catch. Basically at the bird body
the soothsayer eats away only pectoral and leg muscles, throwing all rest on
the ground for pleasure to numerous flies and bugs. This animal is the female.
Males of these species are smaller, besides they are able to fly and do not
differ in such appetite.
Having refreshed itself, the female starts to involve the male for pairing.
She keeps all legs for the tree branch, having raised an abdomen up. On the
end of abdomen the special repugnatorial gland turns out and in air delicate
specific aroma is spreading. This invitation to pairing influences on males
irresistibly - soon on the branch where the female is sitting, uttering dry
paper rustle three males falls at once. When first of them finds the female,
she hides the repugnatorial gland and the male gets on it from above. And while
the male carries out the duty to the nature, the female turns to him and quietly
decapitates the groom do not resisting to it. Then she starts to devour his
body still continuing pairing. For millions years while soothsayers exist on
the Earth, their breeding rituals had remained same awful.
Some days after pairing the soothsayer female lays some egg capsules on leaves
from the bottom side. After that she ceases to eat - she has executed the parental
duties, and now she is waited with fast death. But from eggs larvae soon burst.
They fall on the ground and first time are fed very originally: finding rotting
berries, the tiny soothsayer sits near it and catches tiny insects, flying to
be fed up. It quickly grows, and up to an autumn cold snap has time to molt
few times and to grow up from 5 millimeters up to 2 centimeters. Young insects
bury in foliage and wait winter in hibernation. But it will be possible to the
little part of them: bushgophers include insects in the diet, and they especially
love tiny soft soothsayers.
More and more time a circle of life is closed. In the nature always it happens
so - only one of set of predators will grow to maturity, and practically any
herbivore will not die the natural death... excepting the male of saigochenia.
Exhausted by rut, males of this hoofed mammal species in huge amount perish
an autumn. The share of dead ones among old males is especially high: hormonal
changes and exhaustion kill practically all males older than five years while
females live much longer. This is the payment for an opportunity to have posterity.
But anything in nature does not vanish completely: the dead saigochenia male
becomes an object of attention of running monitors. Near the carcass of large
animal at times up to ten of them gather. Huge lizards tear apart belly of dead
animal, peel skin and devour its interiors and flesh. They accumulate fat before
wintering, therefore they try to not waste time on fight or rivalry. In some
days they eat all rests of begun to rot meat also will go away.
Winter in Central Asia of Neocene time is enough mild: is allows even heat-loving
tropical species to occupy bushy plains. But to the north, on border of Europe
and Asia, on the western spurs of northern Ural the climate is only a little
softer than that was in far Holocene. And there struggle for life passes not
less sharply, than at the warm south.
Bestiary |
Cherry soothsayer (Cerasomantis giganteus)
Order: Soothsayers (Mantodea)
Family: Mantidae
The huge predatory insect living in branches of bushes. It
grows to length 30 cm at thickness of flat body only 1,5 cm; thus, the body
volume of this insect nevertheless is not so big, despite of size, and its tracheal
respiratory system copes with maintenance of the body with oxygen.
This insect eats other insects and tiny vertebrates, to time of fruit ripening
it becomes sexually mature and is fattened by birds, trapping them in branches
of bushes. In connection with change of diet during life the insect has age
change of appearance. The young not sexual matured insect at first looks like
stick (all legs and body are thin, painted like bark color). Later, when the
insect had increased in size (approximately up to 13 - 15 cm) leaf-looking outgrowths
on forward prehensile leg pair develop, simulating leaves. The body and walking
legs during all life have bark coloring, the relief pattern allowing the insect
to imitate bark more precisely is only increased at them. At an adult insect
prehensile legs imitate large leaves slightly eaten round by insects, body is
wide, with scalloped outgrowths on edges and pattern imitating bark. On joints
of walking legs flat roundish outgrowths of bright red color representing ripe
berries develop. Due to this the soothsayer can attract the possible prey -
tiny birds eating berries. It frequently catches young berryfinches. This catch
is rich in proteins necessary for egg formation. The female of the soothsayer
is large and wingless, the male is longer (length up to 20 cm), winged and more
graceful.
The breeding season begins at the end of summer and passes the same way as at
all soothsayers. The female attracts the male by odorous secretions of abdominal
glands. One pairing which traditionally costs to the male its own life, suffices
for the female to lay 5 - 6 capsules (oothecas) with eggs, on one hundred or
more eggs in every one. At the beginning of autumn the female lays last capsule
and perishes. Eggs are left with larvae which spend winter, having hidden in
fallen leaves or ground cracks. Up to the falling to hibernation they start
to eat and have time to molt once. When the spring begins young soothsayers
leave shelters and begin feeding by insects on branches of bushes.
Running monitor (Suchovaranus velox)
Order: Squamates (Squamata)
Family: Varanidae
The large predatory lizard of plains and foothills up to 2,5
- 3 meters long. Constitution is very harmonous, half of body length accounts
for thin tail, head and neck makes up in length about half of body length (not
including tail). Head is very narrow, the skull is compressed from sides, neck
is mobile and flexible. Teeth are sharp, inclined back, similar to knife blades.
On the head there are lines of large convex scales, forming at old animal the
"crown". Legs are long and thin, leg position is almost vertical.
Hind legs are 1/3 longer than forepaws, the animal can run small distances on
two legs. Claws on fingers are adapted for catching and holding of small catch.
Coloring of body is changeable: from striped greenish grey in bush thickets
up to almost one-color sandy-yellow one. Moving in new habitats, the animal
changes coloring during two - three days.
This lizard lives in thickets of bushes, hunts small animals and birds, sometimes
eats carrion. It hibernates in holes which digs by itself or occupies existing
ones. To wintering the basis of tail strongly gets fat because of fat stock
necessary for successful hibernation. In spring in breeding season males arrange
fights, pushing by "crowns". Females lay up to 15 eggs in small hole
and do not care of posterity. The posterity hatches after 2 months of incubation.
Sexual maturу animal becomes at the age of 6 years, lives till 30 years.
Berryfinch
(Cerasipyrrha pyrrhuloides)
Order: Passerine birds (Passeriformes)
Family: Finches (Fringillidae)
Picture by Alexander Klimenko and Vladimir Andreev
The small bird (in size it is less than sparrow), descended from the modern
bullfinch (Pyrrhula pyrrhula). Due to people this species of birds presently
have received advantages in survival: artificial plantings of trees had expanded
its forage reserve. Bullfinches are rather usual birds in cities in winter time.
The berryfinch had decreased in size: this is the adaptation for existence in
conditions of a hot summer of the Central Asia (the relative surface of the
body is increased). Bird keeps in winter in large flights (up to 50 - 100 birds),
which are separating by summer to breeding pairs. Wings are short, tail is long,
flight of the bird is fast and maneuverable. Coloring of the body is bright:
body top is brown with white cross strips on wings, head is black with green
metal shine at males (head of the female is matte). Stomach of the male is bright
red with violet shine, at the female and young males it is brown with light
strokes along feathers. Beak is thick and black. Birds eat fruits of bushes,
eating pulp together with seeds. The bird can split large fruit stones, reaching
an edible kernels. In winter bird can eat insects, finding them in cracks of
a bark.
In middle of spring the breeding season begins at these birds. Inside flights
pairs are formed which occupy appointed territory and build nest looking as
a deep cup of grass and sticks in the richest thickets. In nesting period birds
keep reservedly, but nearer to an autumn when bushes fructify, these birds meet
by big flights. Nestlings are feeding by insects, but later they change it to
vegetative food. In clutch there is up to 5 eggs, both birds (the female in
the afternoon, the male at night) hatch. The young growth is feed up by both
partners. For summer breeding pair hatch usually 2 hatches, in droughty years
- only 1.
Voice of a bird is mellow singing, shout of alarm - the shrill long chirp.
Bushgopher (Dromocitellus canicula)
Order: Rodents (Rodentia)
Family: Squrrrels (Sciuridae)
The small rodent, the descendant of modern ground squirrels
(Citellus). The animal has increased in size in comparison with an ancestor,
had adapted from burrowing habit of life to ground running one. This rodent
builds wattled drays of grass and sticks in bushes, lives the big colonies ("towns"
numbering up to 40 - 50 drays). Sometimes the large colony almost completely
rounds up group of bushes. In middle of thickets, in the most safe place the
dray of dominant pair is placed.
The animal is 25 - 30 cm in size, length of the tail is 5 - 6 cm, weighs up
to 1,5 kg. By proportions it reminds small short-legged dog. Hind legs are longer
than forelegs, the waist is a little bit higher than shoulders. The frightened
animal highly jumps up, uttering shrill squeak - the sound of alarm. Paws are
thin, digitigrade, fingers are not concrescent, in case of need the animal can
bring forage to the mouth by paws, swarm up bushes and run fast. The head is
large, short, has cheek pockets. Ears are short, slightly jut out from wool.
Eyes are big, animal has keen sight. Coloring of the body is ochre - red with
large white spots on the back, stomach and throat are white. The tail is covered
with rich hair, the bottom side of it is white. In case of danger during an
alarm jump the animal presses tail to the back and fluffs up its white inner
side, making it well seen. Cubs have no white spots on the body before sexual
maturity.
Bushgopher keeps by big colonies (up to 60 - 120 animals), in every colony there
is the dominant pair. At the lowermost step of hierarchy young animals have
not formed pairs stand. Pairs are rather constant, sometimes they are kept up
to the end of life. Pair keeps amicably, animals spend a lot of time together,
feed and clean each other, together build and repair the dray. The male can
bring forage to the female when it looks after cubs. Per one year it is 1 pack,
7 - 8 cubs (in droughty years - only 2 – 4 ones). Cubs are hairless and blind,
become covered by wool at 10-th day, begin to see clearly for 15-th day of life.
From monthly age they start to eat food of adult animals. Sexual maturity comes
at the age of 4 months, life duration is about 4 - 5 years.
Saigochenia (Saigochenia dolichops)
Order: Even-toed ungulates (Artiodactyla)
Family: Bovids (Bovidae)
Picture by Leonard Popov and Eugeny Hontor
Initial image by Pavel Volkov |
One of hoofed mammal species survived in climatic changes
and ecological accident of the end of Holocene and the epoch previous to Neocene
was the saiga (Saiga tatarica). This species have shown the viability in late
Pleistocene and Holocene: the saiga has gone through extinction of mammoth fauna
(it was one of its components), and in XX century from dying out species saiga
became numerous and trade one, sharply having increased the number as the result
of protection. The saiga is unpretentious animal, capable to live without drinking
water a long time and to eat rigid grass. This species tolerates keen frosts
of continental climate of the Central Asia. In other words, it has many opportunities
for the survival.
The saigochenia is the descendant of the saiga had adapted for inhabiting in
light forests and thickets of bushes which began to cover plains of the Central
Asia in Neocene. The shape of this animal had changed in comparison with an
ancestor. The saigochenia had became larger, but more graceful, legs and neck
of the animal were elongated. Coloring of wool from one-colored yellowish ("desert")
one became spotty: on yellowish background there are small black spots on shoulders,
hips and crupper. On the crown there is a bunch of long white hair. The head
from short became wedge-shaped, horns had decreased also they had became similar
to hornets of the giraffe, and the proboscis was enlarged and became high-grade
prehensile organ, as at South-American fossil mammal Macrauchenia. Due to the
trunk saigochenia had got an opportunity to eat branches of bushes and small
trees at height up to 3 meters. Horns are reduced, as for such fragile long-necked
animal competition with each other by butting had became unsafe for life. Saigochenias
establish superiority, pushing by necks and shoulders. Shoulders of males are
covered with long hair like lion's mane. Sometimes such mane grows on chest
and mounts to the stomach. The size of mane correspond to the level of the contents
of sexual hormones in organism of the male, therefore females prefer to be coupled
to more mature "long-manned" males. Also contending males estimate
each other the size of mane before the possible breeding fight. The dominant
"long-manned" male gathers harem of several females and protects it
from contenders. It declares the right on a harem, uttering loud low through
the proboscis. Usual voice of the saigochenia is the silent snort similar on
horse’s one.
The rut occurs at the end of summer when berries ripen and it is possible to
food by many kinds of forages. At this time males search for the bulbs of bush
lily containing stimulating substance. In spring the female gives rise to pair
of cubs which stay with it up to new season of pairing. Cubs are born well-developed,
in some hours after birth are capable to follow mother. Sexual maturity comes
at 3-rd year of life, life duration is till 30 years.

Bush lily (Leucolilium stimulatum)
Order: Liliales
Family: Liliaceae
This seasonally green plant is the species of bulbous plants
of family Liliaceae. It grows among thickets of bushes in woodlands of Central
Asia. Plant prefers damp habitats, growing more often near reservoirs. Stem
is high, upright, leaves grow by whorls of 7 - 8 ones. Flowers are clear white,
gathered in cluster of 4 - 6 floscules. Inflorescences grow at top of the stalk
and in axils of top leaves. Flowers emit the strong smell involving pollinating
insects at night. This species blooms in the beginning of spring, seeds ripen
to the middle of summer. By the end of summer the elevated part dries out.
The bulb of bush lily contains substances, by the chemical structure similar
to sexual hormones of the saigochenia, therefore in breeding season these herbivores
search by smell and dig out its bulbs. Now the similar way maral deer in Siberia
search for the plant leuzea (Leuzea (Rhaponticum) carthamoides), or "maral
root", rich in stimulating substances.
Fragile scales of lily bulb is the guaranty that the animal will not destroy
all plant entirely. If in ground even a little of bulb scales will remain, each
of them will grow to new bulb after two or three years.
