UNIT 6 FLORA AND FAUNA

INTRODUCTION

While thinking about animals we first of all remember domestic animals, that live with people. Many people keep pets and the most popular are: cats and dogs, but people also can keep canaries, parrots, mice, goldfish and hamsters. Farm animals include: rabbits, sheep, cows, pigs, horses, chicken, goats. In a zoo or in the wild we can find these wild animals: a tiger, lion, bear, leopard, camel, gorilla, elephant, monkey, zebra, giraffe, etc. Some common insects are: a bee, ant, mosquito, butterfly, fly, spider. And the most common birds are: an eagle, sparrow, hawk, goose, duck, swan. Some creatures swim (whales, sharks), some move along the ground (snakes, snails).

6.12 Read the text “Coniferous and Deciduous Forests” and do the exercise after it.

CONIFEROUS AND DECIDUOUS FORESTS

Coniferous and deciduous forests are two of the tree major types of forest. Life in the two areas has developed very differently, due to the differences in climate.

Coniferous are so called because their seeds are produced in cones. Vast coniferous forests of spruce, cedar, larch, pine and fir are found where conditions are cold and harsh, with brief summers and low rainfall, i.e. northern parts of America, Europe and Asia and in the world’s mountainous areas. Further south, conifers exist alongside deciduous trees in mixed forests.

Most conifers have needles instead of leaves (their smaller surface area means less water is lost by evaporation) and the majority are evergreen (never bare of needles), so they can produce food all year round.

The word deciduous describes trees that shed their leaves once a year. They are flowering plants, mainly blooming once a year in the spring. Deciduous forests are found in areas with relatively mild temperatures and plenty of rainfall throughout the year. Most of Europe, Japan, eastern Asia and the eastern USA were once covered in forests of deciduous trees, like oak, beech, maple and ash.

Deciduous trees have large, broad leaves to make the most of the many months of sunshine for photosynthesis. They are lost before winter when strong winds and cold would damage them. Each tree provides homes and food for a large wildlife community. Rich soil and plenty of sunshine allow many different plants to flourish. These support still more animal life.

● What trees are common in our region?

6.17 Read the text “Siberia’s Fauna Is Amazingly Rich” and decide whether the statements after the text correct or incorrect.

SIBERIA’S FAUNA IS AMAZINGLY RICH

There are many species of fauna in the vast expanses of tundra, taiga and water-meadows, the numerous rivers and lakes. Scientists have registered 74 species of mammals on the territory of the region, more than 320 species of birds, 4 species of reptiles, 5 species of amphibian and over 40 species of fish.

In the tundra are the reindeer, polar fox, lemming and many species of birds. On the islands and mainland one finds the polar bear, and in the coastal waters, the Bay of Ob and other bays the sea hare, the ringed seal and the white whale. Further south in the tundra the wolf and the wolverine are common.

The animal world of the taiga is even richer: the squirrel, white hare, chipmunk and letyaga, as well as the brown bear, fox, marten, sable, lynx, weasel, Siberian pole cat, badger, wolf and wolverine. The pride of the taiga is the moose. The mole and musk-rat are widespread and there are many colonies of the water rat and the Asiatic beaver, which have survived in Malaya Sosva and Demyanka. The zone is also being energetically settled with imported American mink.

The taiga is full of birds. Here you will find the wood-grouse, hazel-grouse, black grouse, nutcracker, osprey, great grey owl, Tengmalm’s owl and pygmy owl and in marshes the willow grouse, crane and great snipe. The old beds of rivers and lakes are densely populated with ducks, snipes and gulls. The trumpeter swan nests here, as do the red-throated and black-throated loon and the red-necked sheldrake.

The forest-steppe is the home of the stoat and fox, the mountain hare and Siberian polecat, the steppe polecat, the badger, the musk-rat, the black grouse, the quail, the hazel-grouse and various species of water-fowl. The wild goat and moose are found here, and also their constant companion – the wolf.

Many of the animals in the Tyumen Region are hunted for commercial purposes. There is also a great deal of commercial fishing here. There is world-wide demand for the Siberian sturgeon, white salmon, muksun, peled (syrok), Siberian whitefish. Ide, dace, roach, pike, perch and crucian are popular on the local market.

6.21 Read the text below and do the exercises after each part.

THE RICHNESS AND DIVERSITY OF RUSSIA’S NATURAL RESOURCES

■ Russian Arctic regions stretch from the North Pole to the border of the Eurasian continent. Ice is the major feature of the Arctic. Climatic conditions here are extremely harsh, even in summer air temperature approaches 0˚C. Snow is the only form of precipitation the year round. During the long winter months the Arctic is submerged in stark darkness, while in summer the sun never passes below the horizon.

In spite of the unfavourable environment life still exists in the Arctic. Mosses, lichens, creeping and dwarf shrubs are to be found growing on the shallow arctic soils of the islands scattered in the Arctic Ocean. The sea is habitat of about 200 species of algae and abounds in animal plankton.

Auks and gulls build their nests on the rocks, forming great colonies. Among the typical for this zone mammals mention should be made of walruses, seals, killer whales, whalebone whales, lemmings, and Arctic foxes. White bear has long been the symbol of the Arctic.

► 1 Which words in the passage have the same meaning as:

severe, adj common, adj create, v

area, n bush, n?

2 What do 200 species refer to?

3 How do you pronounce the following: algae, walrus, horizon?

4 What is the dominant feature of the Arctic landscape?

5 Which words in the passage have the opposite meaning to:

above, adv short, adj lose, v?

6 Are lemmings predators?

7 What is the symbol of the Arctic?

8 Explain the meaning of the words mosses and lichens.

9 How do you understand the meaning of the verb abound?

■ The tundra occupies a vast area. In the European part it only skirts the seashore, while in Siberia it extends as far as 500 km deep into the mainland.

Strong winds are characteristic of the tundra. Winter is long and cold; summer is short, with frequent and prolonged drizzles. Most of the tundra is in the permafrost zone. A typical tundra landscape features a waterlogged plain with numerous shallow ponds.

The tundra environment is monotonously unvaried. Plant life is represented essentially by mosses and lichens.

During the short period of vegetation the green land plants and algae in the innumerable ponds produce organic matter in quantities sufficient to feed thousands of migrating birds (geese, ducks, sandpipers, etc.), and endemic mammals (reindeer, Arctic foxes, lemmings, etc.). Water bodies in the tundra abound in fish (salmons are prevalent).

The people living in this zone are engaged in pasture reindeer-breeding and fur and feather production.

stretch, v water reservoir

vegetation, n dominant, adj?

2 What does 500 km refer to?

6 What are people engaged in?

7 Explain the meaning of the words permafrost and breeding.

■ The tundra is fringed in the south by a narrow strip of the forest-tundra, which is a kind of transitory zone between the tundra and the taiga.

The species composition of sparse growth varies in different parts of the forest-tundra: birch on the Kola Peninsula, spruce to the east as far as the Urals, and larch in Siberia.

The forest-tundra is populated by all typical for the tundra animals, but there are also animals common for the taiga (greater-spotted woodpecker, wood-grouse, hazel-grouse, brown bear, elk, etc.).

Reindeer-breeding, hunting and berry-picking make up this zone’s economy.

► 1 Which words in the passage have the same meaning as:

sort, n various, adj fauna, n?

2 Where is forest-taiga located?

3 What animals are the most popular?

4 What are people engaged in?

■ The taiga extends from the forest-tundra margin to the line Moscow-Ufa-Yekaterinburgh-Omsk-Krasnoyarsk in the south (taking in the Altai and the Sayan) all along Russia from its western borders to Kamchatka and Sakhalin. The taiga landscape is uniform and stern. The major tree species in the forests are larch, spruce, pine, Siberian cedar, and silver fir. In some places the gloomy colours of boreal coniferous forests are enlivened by the lighter spots of birch groves, in others the coniferous are mixed with aspen and alder. Pine forests grow on dry sand soils.

Life conditions in the taiga are rather hard – in summer air temperature may happen to be +35…+38˚C; in winter –50˚C. Fauna in the taiga is much more varied than in the tundra. There are voles, flying squirrel, greater-spotted and black woodpeckers, crossbill, common viper, etc. The taiga forests are the main source of fur (sable, beaver, squirrel, fox, mountain hare). The taiga is also the major supplier of timber.

At its south-western border the taiga gradually gives way to mixed coniferous-deciduous forest in which further to the west and south the conifers are replaced by broad-leaved species (oak, maple, lime, ash, elm). Here lie the vast expanses of mixed and broad-leaved forests of the European part of Russia. This area has sufficient moisture throughout the year, summer is rather warm and winter not too frigid. The following animals are typical for the European broad-leaved forests: marten, European mink, wild boar, roe deer, golden oriole, common nightingale, bear, badger, hedgehog, bats.

► 1 Which words in the passage have the same meaning as:

dark, adj main, adj slowly, adv

wet, adj wood, n cold, adj?

2 What do –50˚C refer to?

3 How do you pronounce the following: species, coniferous, deciduous, throughout?

4 Can you show on the map the extension of the taiga in Russia?

5 Do Siberian and European forests differ? Give examples.

■ The forest-steppe is a transitory zone featuring a whole complex of forest and steppe species. Along with marten, squirrel and elk there are ground squirrels and marmots; kestrels, wood larks and grey warblers build their nests in the thickness of trees and bushes, while the steppe is inhabited by steppe eagles, quails and skylarks.

The forest-steppe is highly fertile. In western areas 70-80% of land is under crop.

Today almost all steppe lands are turned into ploughland and are in fact a big cornfield interrupted only occasionally by small patches of wild nature.

The latter host such steppe birds as bustard, little bustard, steppe eagle, skylark, also ground squirrel and other animals.

A forestation and irrigation aimed at “softening” this zone’s climate bring in considerable changes in the natural conditions of the steppes, attracting forest animals and plants and generally improving life environment.

► 1 Which words in the passage have the same meaning as:

nowadays, adv sometimes, adv

factually, adv part, n?

2 What does 80% refer to?

3 Explain the meaning of the words ploughland, forestation.

4 What improves the environment of the forest-steppe and why?

■ Much space between the steppe zone and the Caspian Sea is under semi-desert. Winter is rather cold here (mean January air temperature is about

–10˚C), spring is short, and the long summer is hot and dry (mean July temperature is normally +22…+25˚C). The open spaces of sun-parched land, covered in places by a low growth of wormwood are spotted with bitter lakes and solonchaks.

Deserts are to be found only in the southern part of the Caspian Depression: to the east from the Volga delta is the sagebrush-fescue desert; to the west, the sandy desert.

► 1 Which words in the passage have the same meaning as:

territory, n severe, adj salty, adj?

2 What do –10˚C refer to?

3 Explain the word solonchak.
