Drawing of someone who lives in the mountains. Mountain nature: animals and plants

The third largest land area, almost 50 million square kilometers, on earth is occupied by mountains. Conditions in the mountains differ significantly from the plains: much colder, more precipitation, long winter, there are frequent winds, thin air and little vegetation.

The main feature of the mountains is low pressure and lack of oxygen in the air, which is a very serious obstacle to the habitat of living creatures.

Starting from 4 thousand meters above sea level, most living beings, including humans, experience so-called oxygen starvation. A living organism deprived of sufficient oxygen cannot withstand normal stress, and in some cases can lead to death.

And yet, these places are by no means lifeless. In these extreme conditions life has not stopped, and enough people live in the mountains large number animals and birds adapted to these conditions.

On different continents, peculiar species live in the mountains. So in South America, in the Andes at an altitude of more than 4000 meters, alpacas, guanacos, and vicunas live. These are peculiar relatives of camels known to us. They have the same long legs and neck, but there are no humps, and they are smaller in size.

Several species of mountain goats and aurochs live in the mountains of Europe, Asia and America. These are wild animals and are mainly hunting species, now of course not commercial, but purely amateur. The mountain goat is considered honorable hunting trophy for most hunters.

In the mountains of Europe and Asia you can see snow leopards, beautiful and fast big cats, which, being predatory, find their prey there in the mountains. Because of its beautiful fur, snow leopard For many years it was a desirable prey for hunters. Now this animal is on the verge of extinction and is listed in the Red Book.

Another one lives in the mountains of Tibet and Pamir amazing view mountain animals - . These huge, buffalo-like animals, covered with long fur, generally prefer to live only in mountainous areas. Their body is so different from lowland animals that they are unable to survive at lower altitudes.
Large lungs and heart, as well as a special blood composition with increased hemoglobin, provide oxygen supply to the yak’s body when it is deficient in the air. A thick layer of subcutaneous fat and the absence of sweat glands provide it with the ability to tolerate low temperatures, but at the same time create overheating of the body at temperatures above 15°C. Under normal conditions, yaks are much hardier than ordinary bulls, and females, compared to cows, produce more milk with increased fat content.

People noticed the characteristics of mountain animals and their endurance a very long time ago. One of the first people to domesticate a wild goat and began to receive fluff and milk from it. Several thousand years ago, Indians living in the South American Andes tamed llamas and used them as beasts of burden. Alpacas and vicunas began to be bred in order to obtain excellent fur, which is mainly used for export; guanacos are mostly semi-wild and serve as a source of meat and wool for the local population.

Residents of Tibet and the Pamirs domesticated yaks and began to use them as beasts of burden and for meat, milk and wool. In order to impart special qualities of the yak to domestic cattle, yaks were crossed with Mongolian cows and a hybrid was obtained, the so-called haynaks, which have the calm disposition of an ordinary cow and the endurance and productivity of a Tibetan yak. Hainaks can live in flat conditions, so they began to be bred in Russia, Buryatia and Tuva.

Living conditions in the mountains are very different from those on the plains. As you ascend into the mountains, the climate changes: the air temperature drops, the wind strength increases, and often the amount of precipitation increases, and winter becomes longer. High in the mountains the air is thin and it is difficult to breathe. The nature of the vegetation from the foot of the mountains to the peaks changes over just a few thousand meters, counting vertically (see article “Vegetation of the High Mountains”).

Natural conditions in the mountains change not only with height, but also when moving from one slope to another. Sometimes even neighboring areas of the same slope differ in climate and vegetation. It all depends on the position of the site in relation to the cardinal points, the steepness of the slopes and their openness to wet or dry winds.

The living conditions in the mountains are varied, their fauna. In the middle mountain zone, where the climate is not yet too harsh and there are forests, as a rule, it occurs significantly more types animals than on the same area of ​​the adjacent plain. The fauna is rich in the relatively narrow strip of the upper limit of the forest, especially on the subalpine edges. At higher levels, the number of animal species begins to decrease noticeably. The tops of high mountains, where eternal snow lies, are almost devoid of life.

In the Alps, traces of chamois were seen on the top of Mont Blanc (4807 m). Very high in the mountains - almost up to 6 thousand m - mountain goats, some types of sheep and yaks come. Occasionally, after them, a snow leopard or snow leopard rises here. Of the vertebrate animals, only vultures, eagles and a few other birds penetrate even higher. The bearded vulture was seen in the Himalayas at an altitude of 7.5 thousand meters, and the condor was seen in the Andes at an even higher altitude. When climbing Chomolungma (Everest), climbers observed alpine jackdaws at an altitude of 8100 m. A snow partridge nest with a clutch of eggs was found in the Nepal Himalayas at an altitude of almost 5.7 thousand m.

Often the same animals are found in several mountain zones, but, as a rule, their numbers are significant only in one of them, the most suitable for the life of a given species. Large number species outside one or two of their most characteristic zones are rarely or not found at all, and only a few can be seen in different zones mountains Therefore, in every mountain zone your animal world. It consists, as a rule, of a number of species close or identical to those found in the fauna of the corresponding latitudinal zone of the Earth. For example, in the tundra belt of the mountains of southern Siberia, called here char, you can observe reindeer, tundra partridge and horned lark, characteristic of the northern tundra.

Snow goat.

Fauna of the Alpine belt of the mountains of Europe, Asia, North America and to a lesser extent North Africa V general outline homogeneous This is explained by the fact that in the highlands of the Northern Hemisphere, living conditions are similar, and the core of the mountain fauna comes from common centers of speciation - the mountains Central Asia and some other mountainous regions.

Many mountain animals live only where there are rocks. Mountain goats, bighorn sheep, argali, as well as goral and musk deer, escape in the rocks from predators. Birds - rock pigeon, swifts and red-winged wallcreeper - find convenient nesting places there and hide from bad weather. The wall climber crawls along steep rocks like a woodpecker along a tree trunk. With its fluttering flight, this small bird with bright crimson wings resembles a butterfly.

Screes form in many mountains; The life of the mountain pika, also called the haymaker, the snow vole and some other rodents is associated with them. In the second half of summer, they all diligently collect blades of grass and twigs of bushes with leaves, lay them out on stones to dry, and then carry the hay under shelters made of stones.

Alpine goats.

The peculiar natural conditions of life in the mountains affected appearance animals that constantly live there, on their body shape, lifestyle and habits. They have developed characteristic adaptations that help in the struggle for existence. In mountain goats, chamois and American snow goat large mobile hooves capable of spreading widely. Along the edges of the hooves - from the sides and in front - there is a well-defined protrusion (welt), and the pads of the toes are relatively soft. All this allows animals, when moving along rocks and steep slopes, to cling to barely noticeable irregularities and not slip when running on icy snow. The horny substance of their hooves is very strong and grows quickly, so the hooves never “wear out” from being abraded by sharp stones. The structure of the legs of mountain ungulates allows them to make large jumps on steep slopes and quickly reach rocks where they can hide from persecution.

During the day, rising air currents predominate in the mountains. This favors the soaring flight of large birds - bearded vultures, eagles and vultures. Hovering in the air, they can spot carrion or live prey from afar. The mountains are also characterized by birds with fast, swift flight: Caucasian mountain grouse, mountain turkey, or snowcock, swifts.

Yak. The long and thick fur on the belly and sides serves as a kind of bedding for it.

In summer it is cold high in the mountains, so there are almost no reptiles there: most of them are heat-loving. They only penetrate higher than others viviparous species reptiles: some lizards, vipers, and in northern Africa - chameleons. In Tibet, at an altitude of more than 5 thousand m, the viviparous round-headed lizard is found. Roundheads living on the plains, where the climate is warmer, lay eggs. What has been said about reptiles is to a large extent true for amphibians, although they penetrate into the mountains a little higher - up to 5.5 thousand m. Of the amphibians common in our country, the Asia Minor frog and the gray or common toad penetrate the mountains higher than others . The upper limit of the vertical distribution of fish is about 5 thousand m.

Snow leopard, or snow leopard.

The lush plumage of mountain birds and the thick fur of animals protect them from the cold. The snow leopard, which lives in the highlands of Asia, has unusually long and fluffy fur, while its tropical relative, the leopard, has short and sparse fur. Animals living in the mountains shed much later in the spring than animals on the plains, and in the fall their fur begins to grow earlier.

Vultures.

Hummingbirds in the Andean highlands nest in caves in large groups, which helps keep the birds warm. On cold nights, they fall into torpor, thus minimizing energy expenditure on heating the body, the temperature of which can drop to 14°. One of the remarkable adaptations to life in the mountains is vertical migrations. With the onset of autumn, when it becomes cold high in the mountains, snowfalls begin and, most importantly, it becomes more difficult to obtain food, many animals migrate lower down the mountain slopes.

Condor.

A significant part of the birds living in the mountains of the Northern Hemisphere fly south for the winter. Most birds that remain to winter in mountainous areas descend to the lower zones, often to the very foothills and surrounding plains. Very few birds, such as the mountain turkey, spend the winter at high altitudes. In the Caucasus, it usually stays near places where aurochs, the closest relatives of mountain goats, graze. The snow here is sometimes dug up by their hooves, and it is easier for the bird to find food. The loud, alarming cry of a wary snowcock warns the aurochs of danger.

Deer, roe deer and wild boars, which are found in the mountains all the way to alpine meadows in the summer, descend into the forest in the fall. Many chamois also go here for the winter. Turs and other mountain goats migrate closer to the upper border of the forest, settling on steep rocky slopes. Some of them go down into the forest. Sometimes they move to the southern slopes, where alpine meadows the snow melts in the very first hours or days after a snowfall, as happens in the Caucasus mountains, or they go to steeper windward slopes, where the snow is blown away by the winds. In the mountains of Siberia, they often spend the winter on “blow out” reindeer, rising here from the forest. If the snow is too deep and dense and the ground lichens in the char are inaccessible to the reindeer, they go back into the forest and feed on tree lichens there.

Mountain turkey, or snowcock.

Following the wild ungulates, the predators that hunt them migrate - wolves, lynxes, snow leopards. Diversity natural conditions in the mountains allows animals to find places for wintering near the areas where they live in the summer. Therefore, the seasonal migrations of animals in the mountains, as a rule, are much shorter than the migrations of animals and birds on the plains.

In the Altai, Sayan and north-eastern Siberia mountains, wild reindeer make seasonal migrations within 10-20 km, and their relatives living in the Far North travel several hundred kilometers to reach their wintering grounds. In the spring, as the snow melts, the animals that have descended migrate back to the upper zones of the mountains. Chamois, mountain goats and other ungulates living in the mountains often die in winter and early spring during snow avalanches.

Alpine insects: on the left - glacier flea; on the right is a springtail.

From mountain animals to different times and in different parts Since the beginning of the world, man has domesticated the goat, in Asia - the yak, in South America - the llama and alpaca. The yak and llama are used in the mountains mainly for carrying loads; female yak produce very rich milk. The alpaca, like the llama, belongs to the group of New World camels (American camels); it produces fine wool, superior in quality to sheep.

We have not yet said anything about invertebrate animals - insects and spiders, however, it is they, and not animals and birds, that are permanent inhabitants of high altitudes. Scientists from India and other countries discovered in the Himalayas at an altitude of 3500 to 6000 m above sea level several hundred species of resident arthropods living here - flies, springtails, beetles, aphids, butterflies, mayflies, locusts, ticks, centipedes, etc. In 1924 when attempting to climb Chomolungma, expedition members discovered active jumping spiders at an altitude of 6600 m. This is so far the highest limit at which living invertebrate animals have been found in the mountains.

Strong ascending air currents bring masses of plant pollen, especially juniper and other conifers, spores, seeds, as well as aphids, winged ants, midges, mosquitoes, butterflies, etc. from the lower zones of the mountains and from the plains. There are known cases of aphids being transported over a distance by the wind up to 1280 km. According to the observations of the Indian entomologist Mani V in the spring-summer months on Mount Pir-Pindzhal in the Himalayas at an altitude of 3.5-4 km, at least 400 dead arthropods were deposited in a section of a snow field with an area of ​​about 10 m2 in 20 minutes different types. Especially a lot of organic residues accumulate at the foot and in the cracks of rocks. Many high-altitude insects and spiders live on them. In particular, they feed on coniferous pollen. small insects Podurs, or glacial fleas, living directly on snow and firn fields.

Groups of invertebrate animals that exist due to organic remains brought by mountain breezes are called aeolian (Aeolus is the god of the winds in ancient Greek mythology). By the nature and origin of their food, coming from other vertical zones, they are similar to deep-sea groups of animals that ultimately exist due to organic remains that sink to the bottom of the oceans from upper layers water (see article “Fauna of the seas and oceans”).

Insects in the mountains often live under rocks; In summer, during sunny hours, the stones become very hot, and the air temperature near them is higher than in other places. Insects also use cracks in the ground and crevices in rocks, rare spots of carpets of alpine plants, soil, small bodies of water and even snow as shelters. Most mountain insects are small in size, living under stones - a flat body shape, thanks to which they can more successfully find shelter. Particularly many insects are found near the edge of melting snow, where the air and soil are moister and where it is easiest to find food - organic remains carried away by melt water. The low density of the atmosphere and the associated low oxygen content in it do not have a noticeable negative effect on insects.

Insects spend the long winter under thick snow cover. In summer they are usually active during hours when the sun shines brightly; therefore, they often alternate periods of intense life and rest several times during the day. But some insects were observed in an active state even when snow began to fall in the mountains and the thermometer showed several degrees of frost. Poduras are unusually resistant to cold. On the plains, moth butterflies are active at dusk and at night; in the highlands they are diurnal: at night the air is too cold for them.

Many insects in the mountains are dark in color and highly pigmented (spotted). This better protects insects from excessive radiation ultraviolet rays, very intense in the mountains. Some species of butterflies, bumblebees and wasps that live high in the mountains have densely pubescent bodies - this reduces heat loss. The latter is facilitated by the shortening of the antennae and legs. High in the mountains, bees and bumblebees are extremely rare, and here flies and other dipterans and butterflies play the main role in flower pollination.

Strong winds in the mountains make life difficult for flying insects. The wind often blows them onto snow fields and glaciers, where they die. As a result of long-term natural selection in the mountains, species of insects arose with greatly shortened, underdeveloped wings, completely losing the ability for active flight. Their closest relatives, living on the plains, are winged and can fly.

Living conditions in the equatorial highlands of Africa are very unique - on Mount Kilimanjaro (5895 m), Rwenzori (5119 m), etc. If seasonal differences in air temperature in these mountains at an altitude of 4-4.5 km above sea level are insignificant, then the daily the fluctuations are exceptionally large. In the alpine desert zone, the air temperature at night almost always drops below zero, but during the day, at an air temperature of about 6°, the soil surface illuminated by the sun heats up to 70° and above. Therefore, almost all animals are active here only early in the morning and late in the evening, for a total of no more than 2-3 hours. For the rest of the day, all living things hide and hide in holes, cracks in the ground, under stones, and only in cloudy days active life lasts longer.

The color of mountain equatorial insects is usually dominated by faded, desert tones; In some insects, on the contrary, the chitinous surface of the body is shiny, silvery, facilitating reflection sun rays. Beetles are characterized by bright colors and rounded elytra, forming a kind of arch above the abdomen; an air gap under the arch of the elytra protects the beetle from overheating.

Thus, insects of the equatorial highlands combine adaptations for protection from both very low temperatures, and from excessively high ones. Many interesting pages from the life of mountain animals have not yet been read and await young inquisitive naturalists.

Living conditions in the mountains are very different from those on the plains. As you rise into the mountains, the climate changes: the temperature drops, the wind strength increases, the air becomes thinner, and winter becomes longer.
The nature of the vegetation from the foot of the mountains to the peaks is also different. In the mountains Central Asia Desert and steppe foothills usually give way to forest, which is first dominated by deciduous and then coniferous species. Higher up there is low-growing, curved downslope subalpine forest and thickets of bushes. Alpine low-growing vegetation begins even higher, vaguely reminiscent of the vegetation of the northern tundra. The Alpine mountain belt is directly bordered by snow fields, glaciers and rocks; there, among the stones, only rare grass, moss and lichens are found.
The change of vegetation in the mountains occurs over just a few thousand meters, counting vertically. This phenomenon is called vertical zoning or zonation. This change in vegetation is in the most general terms similar to the latitudinal zonation of nature on Earth: deserts and steppes are replaced by forests, forests by forest-tundra and tundra.
Natural conditions in the mountains change not only with height, but also when moving from one slope to another. Sometimes even neighboring sections of the same slope have different natural conditions. It all depends on the position of the site in relation to the cardinal points, on its steepness and on how open it is to the winds.
Diversity living conditions contributes to the fact that the mountains are inhabited by many species of animals. In terms of the number of species of mountain animals, the forest belt of the mountains is the richest. The highlands are much poorer in them. The living conditions there are too harsh: even in summer, frosts are possible at night, and there is little food. Therefore, the higher you go in the mountains, the usually fewer species animals. The most elevated parts of the high mountains are covered with eternal snow and are almost completely devoid of life.
Very high in the mountains - almost up to 6 thousand m - mountain goats and sheep come; Occasionally, a mountain leopard, the snow leopard, comes up here after them. Of the vertebrate animals, only vultures, eagles and some other birds penetrate even higher. The bearded vulture was seen in the Himalayas at an altitude of almost 7 thousand m, and the condor was seen in the Andes at an even higher altitude. When climbing Chomolungma (Everest), climbers observed choughs - close relatives of our crows - at an altitude of 8100 m.
Some animals, particularly crows and hares, are found in almost all mountain zones, but most species live in only a few or even one zone. For example, bullfinches and yellow-headed wrens nest in the Caucasus Mountains only in the belt of dark coniferous forests formed by fir and spruce.

Irbis or snow leopard.

On the mountains, each vertical zone has its own fauna, to some extent similar to the fauna of the corresponding latitudinal zones Earth. Animals of the mountain forest belt resemble animals deciduous forests and taiga.

Argali.

The tundra partridge, living on the northern coast of Siberia and on the Arctic islands, is also found in the alpine belt of the mountains of Europe and Asia, where living conditions are similar to the Arctic. Some other animals common in the Arctic also live in the alpine belt of mountains: for example, in the mountains Southern Siberia And East Asia reindeer live. The habitats of deer in Altai are located in most cases not lower than 1500 m above sea level, that is, mainly in the subalpine and alpine mountain belts, where moss and other terrestrial lichens grow in abundance. IN winter time when in reindeer's diet great value have reindeer moss and other lichens; the nature of the snow cover plays an important role in the choice of habitat. If the snow is too deep and dense, then ground lichens are inaccessible to deer. In winter, the treeless slopes of the mountains of the Alpine belt are most favorable for the life of deer, where snow is blown away by the winds, and in clear days melts in the sun.
The fauna of the alpine belt is very unique, where many animals unknown on the plains are found: various types mountain goats (in Western Europe- Alpine ibex, in the Caucasus - tur, in the mountains of Asia - Siberian mountain goat), chamois, Asian red wolf, some rodents, vultures, mountain turkey, or snowcock, alpine jackdaw, etc.
The fauna in the alpine belt of the mountains of Europe, Asia, North America and northern Africa is generally homogeneous. This is explained by the fact that in the highlands northern hemisphere living conditions are very similar.
Many mountain animals live only where there are rocks. Musk deer, mountain goats, Chubuk bighorn sheep, argali and goral antelope escape from predators in the rocks. Birds - rock pigeon, swifts and red-winged wallcreeper - find convenient nesting places there. The wall climber crawls along steep rocks like a woodpecker along a tree trunk. With its fluttering flight, this small bird with bright crimson wings resembles a butterfly. In dry, sunny areas of the mountains, chukar are often found.
Screes form in many mountains; The life of such animals as the snow vole and the mountain pika (otherwise known as hayfowl) is associated with them. Starting from the second half of summer, especially in autumn, these animals diligently collect blades of grass and twigs of bushes with leaves, lay them out on stones to dry, and then carry the hay under a shelter made of stones.

Mountain partridge partridges.

Deer, roe deer and wild boar, found in the mountains up to the alpine meadows, descend into the forest in the fall. This is also where most chamois go for the winter. Mountain goats migrate to the forested part of the mountains and settle here on steep rocky slopes. Sometimes they move to the southern slopes, where the snow melts on alpine meadows in the very first hours or days after a snowfall, or to steeper windward slopes, where the snow is blown away by the winds.

Bearded vulture.

Following the wild ungulates, the predators that hunt them migrate - wolves, lynxes, snow leopards.
The diversity of natural conditions in the mountains allows animals to find places to winter near the areas where they live in the summer. Therefore, the seasonal migrations of animals in the mountains, as a rule, are much shorter than the migrations of animals and birds on the plains. In the Altai, Sayan and North-Eastern Siberia wild reindeer make seasonal migrations of only a few tens of kilometers, while their relatives living in the Far North sometimes travel half a thousand kilometers or more in order to reach their wintering grounds.
In the spring, as the snow melts, the animals that have descended migrate back to the upper zones of the mountains. Among wild ungulates, adult males are the first to rise, followed by females with recently born, not yet strong enough babies.
Chamois, mountain goats, wild sheep and other ungulates living in the mountains often die in winter and early spring during snowfalls. In the Alps in the winter of 1905/06, one of snow avalanches A herd of chamois was buried - about 70 heads.
When there is a lot of snow in the mountains, it is very difficult for wintering ungulates: the snow prevents them from moving and getting food. In the mountains of the Western Caucasus in 1931-1932. It was a very snowy winter. The layer of snow in some places exceeded 6 m. Many deer, roe deer and other animals migrated to the lower parts of the mountains, where the snow cover was less. This winter, roe deer ran into villages and were easily captured. They were caught and kept in barns along with livestock until the snow in the mountains melted and the roe deer were no longer in danger of dying from starvation. At the end of December 1936, snowfall in the Caucasus Nature Reserve continued for four days. At the upper border of the forest, the layer of new loose snow reached a meter. The reserve's scientific staff, while in the mountains, noticed a deep path leading down the slope. They skied down along this trail and soon overtook a large auroch. Only a head with horns was visible from the snow.

Some species of butterflies, bumblebees and wasps that live high in the mountains have thick pubescence on their bodies - this reduces heat loss. The latter is also facilitated by the shortening of the body appendages - antennae and legs.
Strong winds in the mountains make life difficult for flying insects. The wind often blows them onto snow fields and glaciers, where they die. As a result of long-term natural selection in the mountains, species of insects arose with greatly shortened, underdeveloped wings, which completely lost the ability for active flight. Their closest relatives, living on the plains, are winged and can fly.
At high altitudes, insects are found only in places, where living conditions are most favorable for them.

The animals of the mountains have not yet been sufficiently studied; many interesting pages from their lives have not yet been read and await young, inquisitive naturalists. The following reserves provide exceptional opportunities for observing the life of wild animals in the mountains: Caucasian, Crimean, Teberdinsky, Aksu-Dzhabaglinsky (Western Tien Shan), Sikhote-Alinsky, etc.
