Tour to Neocene
|
||||||||||||
In Neocene the area of the seas has considerably increased.
It has caused changes of the Earth climate - the amount of rains has increased,
the areas of savannas and deserts have strongly decreased. But some areas began
to receive so plentiful precipitations, that it began to turn to annual disasters
for inhabitants of such places. In East Asia the result of rains is the strongest
flooding which becomes test for durability for all live beings. Ground in these
places is formed by loess - easily washed away bed. Because of it the relief
is very changeable, the rivers frequently change the channel, changing area
up to unrecognizability.
Plains of East Asia are covered by numerous lakes and the rivers. Winds from
Pacific ocean carry regular rains, but mountain ridges do not pass the most
part of clouds to areas of the Central Asia. Mountains force them to spill plentiful
rains from which the rivers overflow banks and spread to many kilometers.
Probably, animals and plants from other areas of the Earth could not exist in
such conditions more than one year, but plains of East Asia are inhabited with
the live beings which have adapted to annual flooding. River valleys are covered
with rich forests which easily tolerate flooding. Trees form large plank-buttress
roots serving as props at natural disasters. And some figs form the special
shape named "banyan" - from branches the air roots growing into ground
and serving as though by additional trunks grow down. Such tree grows more wide,
than high, covering alone the huge area. It is easier to drown than to overturn
such forest giant. However water does not rise highly and quickly falls down,
therefore figs can grow and fructify normally.
Large juicy infructescenses of figs, similar to violet-brown pears, ripen right
on the trunk and large branches. Here they are the easiest for finding to seed
carriers - large herbivorous vertebrates. Such animals live in flooded forests.
One of them, the mighty bulldeer, the descendant of tiny barking deer, tears
off ripe infructescenses. By velvety lips the animal reaches up to fruits, tears
off it and chews. Juice flows down on its lips, attracting numerous fruit flies.
They are so importunate, that sometimes the bulldeer is compelled to sneeze
and to shake head when especially annoying insect gets into its nostril.
On the bottom part of trunk ripe fruits had been eaten a long time ago by other
herbivores, therefore the bulldeer should rear to regale itself with them. Its
large growth allows it, but nevertheless few appetizing fruits will stay inaccessible
for this massive animal. And especially the bulldeer can not gather the crop
from branches of fig tree. However ripened fruits will hang on the tree not
so long time - there are animals easily gathering them.
The hoot, squeal and shrill cries force the bulldeer to shudder intently. Noisily
having inhaled air, the animal departs from the tree and by one eye looks in
thicket of branches. Noise has rather disturbed, than frightened it: real enemies
walk and attack silently. And on the tree some creatures with grey wool, tenacious
paws and naked red faces appear. At some of them the face is decorated with
white-colored beard and moustaches. They are barbed macaques - masters of forest
crones. Dexterously snatching by all paws, they easily move among branches,
gathering ripe fruits in all forest. They spend a lot of time on the ground
if find there enough food. However now they are attracted by fig fruits. The
clan of macaques quickly strips all fruits which can be gathered. Monkeys are
rather prodigal - if it is a lot of food, they will take a bite and will throw
out more fruits, than will eat. And the bulldeer perfectly knows it, therefore
it does not leave from the noisy neighbourhood in wood thicket. Soon the patience
of the bulldeer appears recompensed: one by one cores of fig fruits plop down
on the ground. While the bulldeer gathers them, one half-eaten fruit falls to
it on the back. Because of unexpectedness the bulldeer stirs up the head and
loudly grunts. If it has guessed to look upward, it would see that from foliage
one and half ten curious red faces of monkeys look at him. But at him obviously
does not suffice mind to do it. Having snorted, the animal again starts to gather
cores of fruits and loudly champs, chewing them. And at the most improper moment
when the horned giant had ate especially juicy core, the fruit falls to it right
on the head. It is obvious not accident - when the bulldeer began to grunt discontentedly,
monkeys in branches have burst out exulting cries. The huge animal had become
for them simply the subject of entertainments. When the bulldeer had bent down
for the next fruit, as on it from branches the branch or the piece of bark fell
- monkeys have to found food not only for stomach, but also for thought. At
last the patience of the bulldeer was terminated, and forest giant walked in
bushes. And when its head had already hided in branches, almost in its back
the fig fruit neatly thrown by the monkey has hit. To the accompaniment of loud
shouts of monkeys the giant bulldeer had quickened its pace to gallop, and soon
its tread was muffled by other forest sounds.
The forest of China territory does not form the continuous area - it is cut
by set of rivers and lakes, edged by bushes and high reeds. And in the forest
it is possible to find shallow ponds, lakes and bogs - the former river-beds
and hollows of lakes. Lakes and rivers serve as watering places for different
animals, and it is the native house for some species of live beings.
Near the coast of lake it is possible to see the different inhabitants of forest.
Cautious bulldeer, the female and her spotty calf, approach to lake searching
of watering place. The female with the cub is especially cautious - she tries
to watch everything, that can be dangerous to her calf. Therefore she departs
from water when the group of barbed macaques is noisily run out of bushes. Large
monkeys at all do not pay attention to bulldeer: they go to water. One young
monkey with curiosity approaches close to bulldeer, and the female quietly bellows.
The calf is immediately hidden behind her side, and mum warningly stamps the
leg and snorts. The curious monkey on the spot departs, fairly being afraid
of strong hoofs of the bulldeer.
Macaques drink water, scooping it by hand and bringing to the mouth. Thus under
water the loud splash is spreading, informing all inhabitants of lake that on
the coast there is someone. This noise frightens some animals, and for one lake
inhabitant there are no more attractive sounds than this one is.
At the bottom of lake the layer of rotten leaves has begun to stir, and from
it the head covered with large scutes has seemed. In the beam of sunlight two
small eyes have coldly flashed, then light has slipped on the figured back of
large creature covered with scales. The monster similar to the tree-trunk come
to life, has quietly waved by wide tail and has slipped in greenish dregs of
lake, having left after itself the rests of leaves turned in water. The most
terrible inhabitant of lake, the giant dalag, has going for hunting. It is the
terrible predator, only a little yield to crocodiles of Holocene epoch in gluttony
and force. And in its menu ground animals take a fair place.
The giant dalag is swimming to the favorite hunting area - to the flat coast
where animals frequently gather for watering. The huge fish applies special
tactics to come nearer to catch: it picks up by muzzle or the back thicket of
floating water plants and comes nearer to the chosen prey at the distance of
exact throw under their covering.
Macaques have slaked their thirst and now their noisy group made to the forest.
When at the coast it became quieter, bulldeer mother and the calf directed their
steps to water. Having looked around and once again having smelt air, the bulldeer
female has begun to drink. And few steps far from her the calf had come to water.
It has not paid attention that right to it the whole thicket of floating plants
is coming nearer. At the next second it cost to the calf its short life.
The huge fish, as if the killer whale, has jumped out almost on the coast and
has seized the bulldeer calf’s muzzle. By sharp jerk aside the giant dalag has
wringed the neck of the calf and, having bent, has dragged prey in water. Bulldeer
female at the first second has recoiled aside, but then, having lowered horns,
has rushed in water after the monster has dragged off her cub. However the fish,
as against it, was nevertheless in the native habitat, and soon spotty side
of the bulldeer calf and huge fin of the giant dalag were seen already in middle
of lake whereas the bulldeer female was helplessly staying down in the shallow
water and plaintively lowed. The spot of roiled silt gradually dissolved in
water, and soon nothing reminded of the drama played at the coast. Only the
bulldeer female some time had wandered along the coast, calling up to itself
by quiet grunt the lost calf.
In large lakes and rivers tens monstrous fishes share coast, gathering bloody
tribute from ground animals. But in lakes and rivers other animals live also,
despite of such neighbourhood.
In shallow water where the way for the monstrous fish is closed, reeds and other
marsh graminoids plentifully expand. Here and there among them it is possible
to see constructions of branches and grass similar to small tents sticking up
on small islets. And not far from them it is possible to notice their builders
and tenants - large ginger-brown mammals. Sitting on hinder legs, they pull
out roots of marsh grasses from soft silt and with appetite eat them. Thus rich
whiskers at their short muzzles shiver, when the animal hasty chews sappy root.
Animals are similar to beavers of Holocene epoch, but they have more long and
narrow tails and not such massive muzzles as beavers. They are beaverats - water
rodents, descendants of the musk rat. They are not so skilful builders as beavers;
they are not able to fell trees and to build dams. And it is not so important:
in conditions of annual strong flooding it is better to live without luggage
and to be the nomad, than the homebody. Tents are the temporary shelter of the
beaverat using before the first flooding.
Beaverats are the peaceful herbivores able to swim quickly with the help of
webby hinder legs. But they share the lake with dexterous and ruthless fisher
predator. And from time to time animals are compelled to divide territory, though
it is most likely simple demonstration, rather than the serious competition:
they at all do not encroach on food resources of each other.
Family of beaverats, the female and four grown up cubs, are fed with rhizomes
of the arrowhead. The young growth recently has ceased to suck milk and has
passed to vegetative forage, therefore cubs while only observe of mother and
elicit at her tubers and leaves of edible plants, cheeping thin. Mother at times
succeeds to have eaten only one tuber from three ones, other cubs get. While
they study, mother has had a hard time - some days she will go to sleep hungry.
And she makes an effort to have a little to eat for itself. And when she succeeds
at last to sink incisors to the large sweetish tuber, at the shallow water the
splash is hearing, and the neighbour of beaverats, the fishing shrew, gets to
the coast. The long-bodied animal with short paws and flat head sits down on
the coast and starts to put itself in order. The fishing shrew is long cleaning
by claws of forepaws, combing rich fur. At the end of toilet it right like the
cat “washes” by forepaw. Rather pleased with itself, the shrew sprawls on the
coast and has a rest. However it is short to indulge in pleasure to it: the
family of beaverats walks absolutely nearby. The large female tries to keep
between cubs and the fishing shrew: sometimes fishing shrews attack young growth
of beaverats.
The affinity of the beaverat female disturbs the shrew’s short condition of
mental equilibrium: the animal jumps up on short paws, curves back, raises tail
above the ground and starts to grin. This animal has something to show: in the
mouth of the fishing shrew forty two peaked teeth stick up, and canines differ
by remarkable length and acuteness. Thus the shrew loudly chirps, constantly
keeping head-on to the beaverat and slightly jumping up on all four paws because
of excitation. Besides, the shrew sprinkles from anal glands stinky musk liquid
on sand. In reply to threat the beaverat female simply turns a head to the shrew
and abruptly growls, showing the yellow incisors ready to fight. Then she leaves
by measured step, knowing, that the shrew simply has no need to rush on her.
Under water the fishing shrew is the mobile and dexterous creature. It swims,
bending by whole body, as if the fish. Hinder legs with swimming membranes between
fingers serve as rudders when the animal makes sharp turn in water. Such way
of swimming allows the fishing shrew to feel like in water almost as freely,
as to a fish.
The body of the shrew under water seems silvery: the fur is covered with special
water-repellent greasing which interferes with wetting of hair by water and
by that protects an animal from overcooling. When the fishing shrew emerges
and gets to the coast, it is enough for it only to stir up well to remain completely
dry.
Under water the fishing shrew searches for forage - crayfishes and fishes. Small
catch, such as shrimps and small fishes, is eating right in water, and the large
fish is pulling out on the coast, but preliminary the shrew kill it by bite
in head.
Having felt the approach of the fishing shrew, underwater inhabitants rush in
all sides or, on the contrary, gather to dense shoals. The shrew almost does
not pay attention to tiny fishes: it is unprofitable to catch such prey, energy
consumptions for catching are not compensated by quantity of had preyed food.
But large fishes and crayfishes are compelled to be cautious.
The young giant dalag weighting about one kilogram, yet not replaced juvenile
cross-striped colouring to “adult” pattern, is hidden from the fishing shrew
in thickets of underwater plants. Its vertical strips help to mask, hiding fish
among stalks. Having hidden in thicket of greenery, the fish stands motionlessly.
But the shrew has one more “secret weapon” - sharp sense of smell. Its muzzle
is extended to the small mobile proboscis, capable to catch odorous substances
in water. And it literally “is hot on the trail” of fish, as if the bloodhound.
The flat head of the shrew starts to smell in thickets of plants, moving stalks
apart. Until the last second the young dalag hopes for cryptic colouring but
when the fishing shrew’s proboscis slightly touches its body, it like an arrow
takes off from thickets, and the shrew rushes in chase. The dalag has important
advantages: it quickly swims and can not emerge for respire air. And the shrew
is compelled to rise on the surface of lake, having given the fish chance to
swim away and hide. But the shrew, as against the dalag, can chase prey a long
time, and the predatory fish, as a rule, "is spread" in one throw
and after that has the long rest. The shrew drives the chosen prey from shelter
to shelter, from time to time rising for air. And at last, when the fish is
already appreciably tired and is swimming more slowly, the fishing shrew makes
solving throw. Having caught up the dalag, it seizes it for the tail by forepaws
and puts in fish’s side strong bite by sharp canine. However the dalag obviously
is not going to surrender so simply: having gathered last forces, the fish tears
itself away from paws of the predator and hides under driftwood. Not wishing
to miss delicious catch, the fishing shrew tries to turn driftwood, approach
to the dalag that from one or from the other side. But a result of this hunting
is not so desired for the shrew. When once again it carelessly pokes the nose
under the driftwood, the hidden dalag bites the mammal to the paw and again
hides in the refuge. The bitten shrew jumps out from water and starts to lick
bleeding wound.
But also the dalag is not too lucky. The wound put by the shrew, appeared very
deep. The fish has lost a lot of blood and feels like bad - it starts to choke.
To facilitate somehow the condition, the dalag rises to the water surface and
hides among floating plants. Due to special suprabranchial organ the dalag can
endure lack of oxygen of water, breathing air. Therefore at the asphyxia the
fish has instinctively risen from the saving bottom to the water surface concealing
of many dangers. The fish turns among crowns of floating plants, involuntarily
betraying itself to the predator observing from above.
The brown - white creature promptly rushed above the water surface. Only one
splash was listened - and the dalag is already in air, seized in ruthless sharpest
claws. It has fallen the prey to the fishing warbler - the large songbird, the
big expert in fishing. Hardly flapping wings, the bird carries catch to the
eyrie, to food two hungry nestlings.
Eyrie of fishing warblers is the big construction plaited of rods, arranged
in forked crown of tree. The middle of eyrie is covered by grass and feathers
among which fish bones are generously scattered. In eyrie two nestlings had
eaten that fishes brought by parents sit. They have already begun to see clearly,
but while they are covered by down. Feathers only few days ago had appeared
in their wings and tail, that’s why chicks look ragged. However these creatures
are remarkable by very good appetite. While mother preserves eyrie, nestlings
sit quietly. But when the father with the weighty dalag in claws has flied to
them, the tree crone is resounded with hysterical peep of hungry offsprings.
The female meets the male at the edge of eyrie. Both birds constantly twirl
by tails, expressing the excitation. At nestlings tails have not grown yet to
full size, therefore they, having stood up, clap by underdeveloped wings and
pull by rump with yet not developed tail feathers.
The male pins the fish body to the sharp twig which is sticking up above the
eyrie. He tears off the piece of meat and shoves it in the mouth of the nestling
peeping more loudly than the brother. Other piece the second nestling gets,
then again the first one, and again the second... Nestlings had eaten almost
one third part of body of the dalag and have calmed down, completely absorbed
by pleasant feeling of satiation. And their parents would not mind having the
nourishing meal: usually they should eat by fits, in breaks between nestling
feedings. Now large catch partly will fall also to theirs lot. Soon from the
dalag body only large head, ridge and tail remain, which one bird dumps under
the eyrie to the big pleasure of flies and bugs.
The season of rains begins: the nature arranges annual test for durability to
all inhabitants of lake-land. In the beginning all the day from Pacific ocean
the fresh breeze blows, then at the evening the sky becomes clouded, and the
rain at night begins. It proceeds, not stopping in the morning, next day, one
week later. Many days from ocean the wind carries clouds, and it is rainy further
and further to the west, in foothills.
Normal life of forest inhabitants is broken during the rain season. The family
group of barbed macaques is hidden from rain in crone of deciduous tree. Monkeys
bunch, nestling to each other and covering cubs from rain. They obviously are
not glad for the rain: their faces look sad, animals are emotionally suppressed.
The large bulldeer tries to hide from bad weather too, having chosen rather
dry place under the sprawling crone of huge banyan. And on the eyrie of butcherbirds
parents protect posterity from the rain by opened wings, replacing in turn each
other on the eyrie. The bird free from watch is occupied with food searching:
fishing is good during the rain. Fishes catch insects falling in water, and
their schools rise to the surface of water.
Consequences of a rain start to have an effect in the life of the forest even
more when in foothills rivers overflow banks because of strong downpours. Water
gradually floods lowlands, filling ponds and lakes and transforming them to
common boundless mirror-like water surface. From water trees stick up by groups
and one by one. They are connected with the lianas, therefore to climbing forest
inhabitants movement in the forest almost is complicated with nothing. And ground
animals have rather hard time. Two bulldeer, mother and the calf, are swimming
across flooded forest. Animals move, pulling water by wide hoofs. Near to animals
few objects made of grass and twigs similar to carelessly plaited baskets float
– they are the rests of beaverat settlement. Sometimes bulldeer mother pushes
the swimming calf, helping it to move. Bulldeer are swimming to the small island
which in dry season looks as hill overgrown with forest. There they hope to
wait any time, eating poor grass and branches of bushes then to cross to the
next island. However it is not too easy to make it: in water near to them the
monstrous fin of the giant dalag appears. For it the flooding is the time of
feasts and easy catch. During flooding dalags are fattened, eating small animals
had expelled from holes and shelters by flooding. The adult bulldeer is too
big for the dalag, and the fish can not attack it. However the bulldeer calf
is the desired catch. Both the dalag, and the bulldeer mother feel it. The female
tries to swim in that way, that to stay between the huge fish and the calf.
Thus the female tries to push the calf that it will reach as soon as possible
saving shallow where from water branches of bushes stick up. At last bulldeer
reach the small island and go to the firm ground. The calf slips on the wet
grass and also falls, but mother helps it to stand. Both animals leave under
the nearest tree, shivering with cold. They are hungry and have strongly got
wet, therefore mother at once shakes itself and starts to browse leaves, and
the calf begins to suck her milk, contentedly wagging tail.
Family group of barbed macaques is not so lucky: flooding has cut off group
of trees on which they were fed, from other forest. Before flooding macaques
had come in searches of food to the peninsula deeply pressing in lake and overgrown
by large trees. But when water in lake has risen, the peninsula had turned to
island, and then the land has disappeared at all, having retained only trees
sticking up from water and the wet monkeys sitting on them shivering with cold.
Macaques like to bathe; sometimes they search for food in water, and if it would
be necessary, they can reach the forest easily. However they can not make it:
in water the huge body of the giant dalag moves. This fish terrifies monkeys,
which at approach of fish only seize branches more strongly, shrilly crying
with fear. And this monster is not the unique problem which monkeys have faced.
For some days they had eaten all in the slightest degree eatable fruits and
had puck off from under bark practically all edible insects. And now they should
chew twigs and rigid leaves somehow to alleviate colic in stomach.
Two days more had passed. The dalag appears in this place less often, therefore
monkeys dare to swim some hundreds meters up to the nearest small island. They
cautiously go down by the trunk to water, encouraging each other by quiet hoot.
The large white-barbed dominant comes into water the first, lets off the tree
trunk and swims. After him young males and youngsters, then females with cubs
and old females go down in water. Cubs sit on backs of mothers to allow them
to swim more freely. Monkeys swim silently, trying to draw by nothing the attention
of huge dalags. When one young female starts to get tired, the old female, her
aunt, takes away the cub from her back and swims beside that the cub constantly
sees mother and does not cry.
The group of monkeys successfully had crossed water space and soon had got out
to the firm ground. Absolutely exhausted macaques get out of water and lie down
on the grass. Many of them almost on the spot fall asleep, only the dominant
male does not sleep: at the small island there can be predators, and he had
to warn clan about danger in time. Clouds gradually dissipate also the ground
gets warm under the sun. Tired monkeys doze, and the dominant male gradually
is sleepy. Having basked in the sun, he gradually starts to breathe regularly,
and his eyes are closed.
On this small island there are no large predators, and the clan is in full safety.
Monkeys sleep whole day and the most part of night, and early in the morning
they wake up, as famine has an effect in full force. And on this small island
it is possible to find a lot of food: here there are not other monkeys, and
rich tree crones promise the true feast. One by one grey monkeys hide in thickets
of trees, from time to time calling to the neighbours sitting on the near tree.
Barbed macaques move on trees, running along horizontal branches on all four
paws. Also they can swarm up lianas on hands and jump from tree to tree, but
large adult animals obviously are rather heavy for this purpose.
On trees monkeys find many fruits, edible mushrooms and leaves. In thickets
of epiphytic plants fat cockroaches, beetles and crickets hide, and macaques
catch them by fingers, rummaging around crowns of plants. If to bark a tree,
it is possible to find larvae of beetles, soft delicate termites or sourish
ants.
In the hollow of one tree it is found the true treasure – the colony of wild
bees with the combs full of honey. This is rare dainty, and macaques are able
to get it. The monkey had found the bee nidus, notifies clan about the valuable
find by loud abrupt shouts. It can seem strange, you see that usually monkeys
willingly use “the right of strong” to appropriate another’s find. But here
the advanced social connections of barbed macaques nevertheless outweigh the
brute force. The social role in clan at the monkey had found the bee nidus,
will appreciably raise, therefore for the sake of such benefit it is possible
to sustain not so pleasant necessity to share the found honey with neighbours.
Involved with shouts, the clan gathers near to the nidus. Monkeys prepare to
regale themselves well, but hide excitation overflowing them. Many of them by
own experience are known, how hurt the annoyed bees sting, therefore monkeys
do everything to not anger insects. They cautiously clean twigs, by teeth and
hands removing from them bark. Then the most courageous and skilled macaques
creep to the nidus and start to immerse cautiously twigs in honeycombs. They
transfer twigs with honey to expecting it members of clan, obviously not depriving
thus friends and relatives. And especially plentifully honey portion they extract
to favorite itself. The members of clan crowding behind, at times enter small
fights for especially seductive honey twig. And at the edge of the tree-trunk
hollow bees gradually gather, and they drone not so peacefully, as earlier...
And when one cub had begun to squeal, when above its head the bee has begun
to hover, the patience of nidus protectors had appeared filled. More and more
bees had shot upwards in air and were hovered above monkeys while, at last,
four-handed robbers were frightened. Squealing and hooting they have rushed
off along the branches, pursued by wild bees, have not left yet from their hollow.
And one monkey had run away, providently had seized in teeth the twig covered
with honey. Appearing in safety, she has quickly licked off precious dainties
and has thrown out this twig before it was seen by neighbours.
Not only bee combs are the favourite object for the monkey robbery, but also
the bird's nests are. In them it is possible to find tasty eggs or nestlings.
And one such nidus monkeys had noticed in forked branches of the large tree.
The leader male and his friend were going to check up the contents of this nest.
This tree trunk is thick, therefore they get on lianas, squeezing them not only
by hands, but also by tenacious feet. They climb on the tree higher and higher,
and soon they reach the nest. Unequivocally it is impossible to tell, are they
lucky, whether or not. The nest appeared completely not empty: in it there are
the female and two nestlings. But they are fishing warblers, and they are ready
to repulse any enemy.
When above the edge of the eyrie the red face with white beard of the leader
of macaques clan had appeared, the fishing warbler female has immediately stood
to threat posture: having fluffed up feathers, she has opened wings and had
began to cry shrilly, approaching to the monkey. Her tail thus had began tremble
from side to side. Nestlings too had started to peep by rasping unpleasant voices,
having risen in full growth and clapping by wings. And when the leader of monkeys
had stretched hand to nestlings, the fishing warbler female had seized it and
had sharply jerked out, having inflicted the deep wound. Indignantly roaring,
the bearded male began to get to the eyrie, pushing away the female by hand.
Suddenly behind his back the flapping of wings had been heard, and from air
on him the fishing warbler male has dived, had flied on disturbing signals of
the female. He had seized the head of the robber and had began to peck it to
forehead and crown, clapping by wings. The female, seeing, that forces have
become equal, had attacked the second macaque, showering his shoulders and back
by strong pecks. Monkeys obviously did not expect so fierce repulse. Closing
the head covered with wounds by one hand, the leader of clan went down on the
liana, and after him his friend, on which back there were some bleeding wounds,
moved. Pair of fishing warblers, sitting on edge of the eyrie, saw off unsuccessful
hunters with loud shouts. They have succeeded to defend the right to live.
Among the animals undergoing calamity during flooding, there are also beaverats.
Their shelters in reed thickets at the first day of flooding had been washed
off by streams of water. But they are much luckier, than other small animals
– beaverats are good swimmers, and during flooding they even have opportunity
to expanse the living area. But young beaverats nevertheless suffer from flooding
- being able to swim well, they can become prey of water predators.
Pack of beaverats - five cubs and their mother - are swimming in yellowish muddy
water. Fur of the beaverat is not such dense as at the fishing shrew, and fatty
greasing does not protect it from getting wet. But hypodermic fat layer gives
to their bodies additional buoyancy and protects against cold water. The suspension
of clay and silt hides swimming beaverats from the predators observing from
below. But the waves spreading from them at movements of webby hinder legs,
allow fishes like the dalag to feel from afar the presence of mammals, not seeing
them. And the huge fish is already aiming at catch, cautiously creeping to the
pack of beaverats from behind. At the surface of water the edge of back fin
of the predator has flashed only - beaverats have noticed of nothing and continue
swimming. The beaverat mother feels that cubs already get tired, and turns off
to the flooded bushes. Here, at the bush, it is possible to have a rest some
time, having hooked by paws for branches. But not all plans will be realized…
When beaverats had to swim only ten meters up to thickets, water behind the
back of the female literally blows up. The huge head of the dalag, coldly shining
by scales, had shown from water, hooking by the bottom jaw the beaverat cub,
swimming last. The small brown lump, spinning, flies some meters in air and
plops down in water. Being stun, it swims by rounds, and at this moment huge
jaws snap it from under water. The family of beaverats in fear is hiding deep
into bushes, and cubs hide under the belly of mother, having buried noses in
her wool and tremble with fear. A long time after this case the family of rodents
does not get out from bush, even when the surface of water becomes quiet.
Not only water predators, but also air ones deprive benefit from flooding. Using
flooding, the fishing warbler diversifies the diet with animals undergoing calamity.
Sweeping past by above water, the bird snatches out by claws small mammals crossing
water from tree to tree. Having sat down on the favorite branch, the fishing
warbler presses catch by claws to the bark and tears off pieces of meat. The
bird gorges on: the most part of catch is eaten by eternally hungry young birds
in eyrie. Using the short period of prey abundance, adult butcherbirds restore
the shape: parental cares are the hard duty of predatory birds.
Gradually flooding comes to an end, and the ground dries out. The water level
in rivers decreases, leaving on the flood-land set of ponds, lakes and pools.
Some of them will quickly dry up, and some can exist right up to the next flooding.
Inhabitants of the river and lakes, received a short opportunity to swim freely,
come back to more habitual places of inhabiting together with water receding.
But some of them get in the real traps, appearing in temporary reservoirs. Then
their life will stop when the reservoir will dry up. However not all inhabitants
of water accept freak of chance as something inevitable.
The giant dalag about three and half meters long appeared among trapped ones:
it had appeared closed in small forest pond. Quickly having finished with several
frogs had the misfortune to appear in this pond together with it, the dalag
began to search for an opportunity of runaway. One of pond coasts appeared too
abrupt, but at the other coast it is possible to find the place to get away.
And at night the fish dares to abandon this temporary refuge and to search for
the big water.
In moonlight from water the huge flat head covered with large scutes is shown.
The mouth of fish is convulsively opening - for such giant movement overland
appears not so easy problem. The fish gets out to the coast, bending the body,
clinging for the ground by spikes of anal fin and pushing by pectoral fins.
The monster creeps slowly, moving aside by muzzle driftwood and the wood dust
brought by the river.
Life of forest inhabitants is gradually returning to the habitual rhythm. The
bulldeer browses bush foliage, pulling ears - midges do not allow it to calm.
And barbed macaques have arranged noisy fishing at the river bank: in the hole
which had stayed from roots of the tree uprooted by streams of water, there
is a whole flight of small fishes. Monkeys try to catch them by hands, however
not every one succeeds to seize quick slippery catch. In the next shallow pool
besides fishes some translucent shrimps swim, visible only when they lift from
the bottom little cloud of silt, touching by thin legs. Adult macaques try to
catch small fishes in the hole, and youngsters not unsuccessfully hunt in puddle.
Fishes and crustaceans, which they catch, together with insects are protein
food, vital to monkeys.
Macaque youngsters have a good time, driving fishes from one end of pool to
another. And the fishing warbler unexpectedly relieves the monotony of their
game: the bird is promptly swept past above the pool, by dexterous movement
of paw having snatched out from water the small fish. Frightened of unexpected
flight of predator, young monkeys run up to the sides with loud squeal. This
bird will represent threat for macaques only when it will not manage to avoid
facing with them. On the hand of the dominant male the long scar, put by the
fishing warbler female after attempt to plunder the eyrie of these birds, will
stay forever. But other inhabitants of this world of forests and waters represent
at times serious threat for monkeys.
The creature covered with stuck leaves and stinky dried ooze creeps out from
the forest with rustling. It is the giant dalag finishing the way across the
forest. The smell of the river gives additional might to the exhausted fish,
forcing it to take heart and to finish struggle for life. But the group of macaques
has noticed the monster, and now can recoup at the fish for that horror which
this fish was inspired to them during the flooding. One of cubs pokes the dalag’s
side by dry branch, and the large fish is convulsively bent, trying to crawl
away faster. And when other branch is poked to the side of the dalag, the fish
opens the mouth widely, trying to frighten off unexpected and undesirable gapers.
And it serves as a signal to the attack. Not daring to approach close to the
creeping fish, monkeys bespatter the dalag with lumps of dirt and the uprooted
bunches of grass. It is an important moment for of macaque cubs: they study
at adults the receptions of protection, and in the future it will rescue life
to somebody of them.
Bending the body, the dalag tries to rescue from so powerful attack. The fish
already crawls to the river literally by jumps and soon hardly slips from the
coast in water. Following to it the lump of dirt flies, blurring in river water
as the mud cloud. The lesson for macaque cubs is finished. In the native habitat
the giant dalag from the toy and object of mockeries turns to terrible danger.
And now not each macaque will risk to climb in water if the fin of this huge
fish has flashed somewhere far away.
Beaverats have constructed to themselves new tents in reeds among shallow waters,
and the fishing shrew again hunts crayfishes and small fishes in the channel
of the river. Life proceeds... up to the next flooding.

Giant dalag (Megachanna augustus)
Order: Percoid fishes (Perciformes)
Family: Snakeheads (Channidae)
In Holocene the role of large water predators was played by
crocodiles. But after climatic cataclysms of boundary of Holocene and Neocene
their area was sharply reduced. And after global ecological crisis they had
been replaced by other animals: in Africa
and North America - by turtles,
and in Asia and South America
– by giant predatory fishes.
The giant dalag is the huge fish of dalag family (Channidae): it is up to 4
meters long, weights over 300 kg. The huge head is covered with bone scutes,
and accounts for 1/5 of common fish length. Mouth is wide. Eyes are shifted
to forward part of head. Coloring of young and adult fishes is different: at
young growth the body is covered with the vertical brown strips divided by narrow
white irregular-shaped intervals, the adult fish has black back, white stomach
and sides covered with pattern of green and brown spots. Back fin of adult fish
is brightly yellow, at males on edge of soft part of fin the black border passes.
At young growth unpaired fins are entirely black. On forehead of adult males
there is rounded yellow spot which size depends on physical condition of fish.
In spawning season conflicts at fishes are solved for the benefit of the individual
at whom this spot is larger.
The fish is well adapted to seasonal changes of water level: it can stay some
time at the land. For this purpose at the giant dalag as at all relative species,
the suprabranchial organ of air breath is developed. On land the fish moves,
bending the body and pushing by spikes of anal fin. For night the fish can creep
up to 500 meters. The fish defines the direction of movement from the contents
of water vapor in air. On air the body becomes covered by special viscous slime
with the big per cent of protein preventing the loss of moisture.
This is the active predator, eating fishes and ground vertebrates weighting
up to 20 kg which can be caught up and drowned.
During the spawning season the male spawns with one or two females. Fishes build
large nidus of floating plants where they spawn up to 100 thousands small grains
of roe. The young growth hatches after 2 days, at week age larvae turn to fry.
The male protects young growth within first two weeks of life. Life expectancy
is up to 50 - 60 years, at three-year age the fish has length about 0,5 m, the
seven-year old fish is capable to spawn.
Fishing
warbler (Dolicholanius piscatorius)
Order: Passerine birds (Passeriformes)
Family: Shrikes (Laniidae)
Bird of butcherbird family (Laniidae). After extinction of
significant part of predatory birds species (order Falconiformes) other species
of predating birds have occupied the free ecological niches. Basically they
were representatives of passerine birds - corvine birds and butcherbirds though
among carnivorous birds in tropics it is possible to meet even parrots.
The fishing warbler has occupied the ecological niche earlier belonging to ospreys
(Pandion) and see eagles (Haliaetus) - it became the specialized feathered fisher.
The shape of bird has also accordingly changed: the fishing warbler is large
bird (body length is up to 50 cm, wingspan is about 100 cm). At it there are
long legs and sharp claws, allowing to snatch out from water fishes swimming
near the surface. To keep such slippery catch, on the bottom side of toes corneous
spikes had developed. The long hooked beak serves for fast catch killing. Coloring
of bird is motley and contrast: the top part of body is dark, ochre red color,
stomach is white. Around of eyes and from eyes up to the beak there is the area
of naked yellow skin. Beak at adult birds is colored white, at nestlings it
is black. Wings are reddish brown with black cross strips; oar feathers are
black with white tips. Long tail is colored black.
It eats fishes and small vertebrates (frogs, water reptiles) snatching them
out from water. The bird eats catch, pinning it on the dry branch. Usually near
the reservoir where the bird hunts, it has favorite place for catch watching
- tree with the broken off branch where catch is eaten. Near the nest also there
are few branches where the catch brought by birds is usually pinning.
Monodin bird, both parents care of nestlings, though the male more often flies
to hunting. The nest build of branches is arranged in forked crown of the large
tree. In clutch there are 2 - 3 eggs, both parents hatch it. Nestlings hatch
naked and blind, begin to see at the age of one week, and later start to fledge.
The young growth spends 2 months in nest, flying off later, but other 2 weeks
young birds are feeding by parents. Sexual maturity comes at 1 year, to this
time beak changes coloring from black to white. Life expectancy is up to 8 -
10 years.
Fishing shrew (Aquasorex planicephala)
Order: Soricomorpha
Family: Natarosoricidae
Large species of mammals
are more vulnerable in case of the changes taking place in the ecosystem. As
a result of ecological accident at the border of Holocene and Neocene efficiency
of many ecosystems had fallen also the majority of large predatory mammals had
died out. Extinction had affected also some water animals, in particular otters
- they had disappeared forever, when many large species of fishes have died
out. Later when the situation had stabilized, the place of otters insectivores
have occupied - fishing shrew is one of them.
The fishing shrew is the descendant of one of species of the Asiatic water shrews
(Chimarrogale), dwelt in Holocene at banks of mountain streams in the Central
Asia.
Length of the body at this mammal is about 40 cm; tail is up to 50 cm. The shape
of this animal shows to observer the good swimmer: flat head, long brawny trunk,
flattened tail, hinder legs with membranes between fingers. Ears are very short,
eyes are shifted to the forward third of head. Brain cavity is low and long,
brain is small. The nose of this animal extends to short mobile proboscis. Teeth
are sharp, at molars there are 2 - 3 sharp tops, canines are large, slightly
jutting out from the closed mouth. The body and tail of the animal is covered
with rich fur; fat glands are advanced for greasing hair. Coloring of fur is
ochre - red, on the head, tail and paws it is darker, on throat and chest there
is white irregular-shaped spot. The mammal spends a lot of time, clearing and
greasing fur. Except for fat glands, at an animal also large anal glands are
advanced, producing unpleasantly smelling musk secret for protection. On forepaws
the thumb has the special "toilet" claw for combing out dust from
fur.
The fisher shrew eats fishes and small water vertebrates, large water insects
(beetles, larvae of dragonflies). It is solitary animal, only the female and
its cubs (up to 5 cubs in one pack) live together. Seasonal prevalence in breeding
is not present. For cub rearing the female digs in river bank the burrow with
exits at the surface and under water. The young growth spends the first 3 weeks
of life in burrow, then starts to get out from home and study to swim. Two-month
old cubs leave the home for few days, and at the age of three months they live
independently. At the age of half-year young animals are already capable to
breeding. Life expectancy is up to 6 - 7 years.
In South America ecological niche of aquatic fish-eater had been occupied by otterodent, the descendant of piscivorous rodent Ichthyomys.
Beaverat
(Pseudocastor moschatus)
Order: Rodents (Rodentia)
Family: Hamsters (Cricetidae)
Habitat: wetlands, lakes, slowly flowing rivers.
Picture by Lambert

Numerous lakes overgrown by reed and reed mace represent the
fine habitat for water herbivores. One of such species is the large rodent,
the descendant of musk rat, living on lakes of China. Before occurrence of people
at the Earth the musk rat lived in Northern America. Basically, if connection
of Northern America and northeast Asia will once again be restored, as it was
more than once during the Cenozoic, musk rats and other species of animals from
New Light easily can get to the territory of China. However occurrence of musk
rats in China has taken place absolutely differently - it has come from the
west, from Europe where it has been acclimatized by people and has got accustomed.
Therefore existence of the beaverat, the descendant of the musk rat, at the
territory of China is one of consequences of people activity. And it has outlived
the original cause at least by 25 million years.
The beaverat is large rodent: it weighs up to 20 kg, body length is about half
meter, the tail is approximately twice shorter. The beaverat is perfectly adapted
to water habit of life: it has webbed hinder legs and wide tail, allowing this
animal to swim fast. Fur has dense short ochre-brown underfur, throat, chest
and stomach are yellowish white. At different animals figure of white spots
on chest varies: sometimes spot spreads even to sides, and sometimes it absolutely
is not present. The muzzle at the animal is wide and short - the beaverat has
strong jaw muscles though it is not able to gnaw and to fell trees, similarly
to beavers. Fingers on forepaws are separate, with long claws, the animal can
catch by them different objects and take food to the mouth, and also put fur
in order. The beaverat eats basically roots and tubers of different water plants,
digging them out from silt by forepaws. It willingly eats soft greenery, snails,
crayfishes and frogs. For food search the animal uses long rich whiskers which
help to grope for food in muddy water during flooding.
The beaverat is the quite good builder. If the animal settles on river bank,
as the refuge to it the big hole dug in soft ground of river precipice is served.
At lakes the beaverat builds of grass lodges in reeds. Here, in shallow waters
in the middle of lake, it is much more safely, than in deep water - huge predatory
fishes like the giant dalag can not reach dwelling of the rodent. The beaverat
strengthens walls of grass tent with the help of silt and branches which the
animal brings from the coast. Usually lodge is constructed for one season (as
against beaver's lodge which can exist by decades) - they simply do not maintain
a long time because of regular flooding.
In the lodge pair of beaverats and their posterity - 4 - 6 cubs before the age
of half-year live. Older cubs start to live independently, and at the age of
2 years they already can birth posterity. Life expectancy is up to 13 - 15 years.
Barbed
macaque (Neopongo leucobarbus)
Order: Primates (Primates)
Family: Old World monkeys (Cercopithecidae)
Habitat: Eastern Asia, tropical forests in basins of large rivers.
Mass extinction at the border of Holocene and Neocene had caused
the disappearance of apes. In Neocene their ecological niches had been occupied
by large descendants of Old World monkeys. This large primate is one of such
analogues of apes inhabiting the Asian rainforests. It is sizable primate:
the adult male growth is about 1,5 m, its weight is up to 50 kg. The female
is approximately 15 % lighter than male. Constitution is massive, tail is short.
Hands are little bit longer than legs and very mobile, the thumb is opposed
to other fingers. It allows the primate to make exact actions and to manipulate
by elementary instruments - sticks and stones. Face skin is naked and red. At
females buttocks are covered with naked pink skin, to breeding season they swell
and become bright red. Wool on the body is grey, on the back it is darker; mature
males have rich white "moustaches" and beard. Wool of cubs is darker,
than at adults – they are almost black.
This ape-like monkey lives in forest, spending a lot of time on the ground,
in case of need it is able to swim. It keeps by groups of 8 - 12 individuals
with the advanced social connections and strict hierarchy. In each group there
is the dominant pair. Dominants show the superiority with the help of loud sounds
and gestures. The special form of dominant behavior is the participation in
education of cubs of group members when during games dominants show their superiority.
Primates differ by high intelligence: they are able to use primitive instruments
and quickly study, observing of neighbours. The system of sound dialogue is
advanced - in "dictionary" of them more than 30 sounds, expressing
emotions, requests, other signals and the information on environmental objects,
are totaled.
These monkeys eat basically plants, fruits and seeds; approximately 30 % of
the diet the food of an animal origin accounts - insects, crustaceans and fishes.
Once in two years the female gives rise to one cub (occasionally twins may be
born). Except for mother, some her close relatives or friends look after newborn
cub. About one year the young macaque remains near to mother, being trained
in the basic skills of communication and survival, however even after its mother
has other cub, this connection does not interrupt. Young females study to look
after cubs, playing with own younger brothers and sisters. At the age of 4 years
young macaques can give posterity. Having become adult, the animal can remain
in group or form own one, including the forming with participation of animals
of the next groups. Life expectancy is about 20 years.
Bulldeer (Cervibos robustus)
Order: Even-toed ungulates (Artiodactyla)
Family: Deer (Cervidae)
Mass extinction of species at the border of Holocene and Neocene
has resulted in disappearance of many species of large hoofed mammals - elephants,
rhinoceroses, bulls, antelopes, hippopotamuses, deer. However some small and
ecologically plastic species of hoofed mammals nevertheless had managed to survive.
They also became ancestors of not numerous hoofed mammals of Neocene. In Neocene
hoofed mammals represent rather relic group among herbivores: they are rather
not numerous in comparison with other herbivores, and areas of them are strongly
breaking up.
The bulldeer is the descendant of small barking deer (Muntiacus), dwelt in Holocene
in forests of Southern and South-Eastern Asia. These species are well adapted
to inhabiting in damp, periodically flooded areas. This animal is very large:
length of the body is up to 2 meters, height at a shoulder is about 1,7 m. Neck
is rather short. By the constitution the bulldeer resembles the Asian nilghai
antelope (Boselaphus tragocamelus) of Holocene epoch, but is a little bit larger
than the antelope. Wide hoofs of this mammal give the big foot-hold; they can
move apart, allowing walking on marshy ground. And between fingers there is
also the small skin area due to which the animal can swim.
At this animal it is the massive head and wide forehead. Horns grow on highly
lifted bases, changing, as at all deer, annually. Each horn consists of very
thick basic antler and short, departing forward and inside, lateral antler.
The basic antlers grow upwards and back, further they are slightly bent forward.
Stumps in the basis of horns are covered with the rich long hair forming "forelock".
At females horns are not present, they have only hair crests. In breeding season
bulldeer males have continuous duels during which they butt and try to tumble
down the contender. Thus animals collide by foreheads, and horns are used mainly
for demonstration: they contact only by ends. On the muzzle there are longitudinal
bone combs from edge of a muzzle along nose bridge to stumps of horns. They
protect eyes of the animal from branches during movement in forest. At the bulldeer
there are canines strongly jutting out from closed mouth. They are used for
courtship demonstrations, and also for protection against large predators. Wool
on the body is dark-brown, legs are covered by cross ochre yellow strips. "Forelock"
at males is gray-white, at females - brown - this attribute is used by animals
for sexing of the neighbour.
This species is solitary animal, supporting contact with neighbours with the
help of voice. The voice of calm animal is similar to silent grunt, the calf
quietly lows. An alarm signal is loud barking, hearing at the distance of some
hundreds meters.
Usually this mammal browses leaves, eats also soft grasses and tree fruits.
It often feeds together with monkeys, eating fruits had fallen on the ground.
Once a year the female gives rise to one or two calves. The calf is covered
with brown wool with rounded white spots. In process of growth spots on legs
merge in cross strips, and on trunk they disappear. At the first year of life
on the head of the cub there are small crests and basements of the future horns.
At the second year of its life horns start to grow, in the beginning without
antlers, then with more and more appreciable antler. The young animal becomes
independent approximately at 8 months after birth, at the age of 3 years the
young female can bring posterity. Life expectancy is 17-20 years.
