A description of photo periodism in plants and animals of the temperate zones

With the possible exception of bacteria, every form of life seems to have an internal means of measuring time. Why do living things need biological clocks? One reason is that such clocks regulate the sequence of tissue and organ formation during the development of many kinds of life. A plant that produced flowers before it grew roots would die.

What you can do for forests Plants of the temperate forest Unlike tropical forests, temperate forests have just two layers of vegetation. The tallest trees have their foliage generally about m above ground and a layer of shrubs and smaller trees underneath, at approximately m.

This is why the soil receives more light than in tropical forests and the undergrowth is luxuriant: During the spring growth, i. This is why many of the species that live on the ground grow, flower and bear fruits before late summer.

Later on, sciophilus plants, i. These plants have extremely efficient mechanisms to capture and use low-intensity light and are able therefore to survive even when the foliage completely covers the soil underneath. The main trees living in this biome are: The beech Beeches Fagus selvatica can reach up to 40 mt tall and have a large, dome-shaped foliage.

Their fruits, called beech nuts, look like chestnut husks, but their thorns do not prick since they are softer and more rounded. They prefer clayey and airy soils, in wet areas, away from harsh winter frost.

They are common in Central and Western Europe, where they are largely used to make timber. They are not only extremely useful furniture, parks, railway sleepers, cellulosebut also commonly used as ornamental trees.

Sycamore Sycamores Acer pseudoplatanus live essentially in hilly and mountainous northern woods only, up to m above sea level. They grow quickly, they like fresh and wet soils and can reach up to mt tall.

Oak Oaks Quercus spp. Oaks can live to — years of age. Their fruits are elongated acorns, protected at the base by a cup-shaped shell. They are widespread in tropical mountain areas Mexico, Himalaya, Indonesiain Mediterranean climates California, Mediterranean areas and in temperate climates North America, Asia, Europe.

Oaks are used to make timber, stairs, parks, furniture, casks and railway sleepers. Aspen Aspens Populus tremula are medium-size trees than can reach up to 25 mt tall. They grow quickly. They like warm and sunny areas.

They are scattered about Central Europe and rarer in Western Europe. They can be grown on uncultivated land to graft them quickly and for long. They are very resistant to industrial waste, and actually grow well in town.

Walnut tree Walnut trees Juglas regia are large trees that can reach up to 20 mt tall. Their fruits are stone fruits they are fleshy fruits, i. Walnut trees are widespread everywhere as fruit trees and for their precious timber which is used to make furniture; they are productively grown in temperate areas: Lime tree Lime trees Tilia cordata are beautiful, straight-trunk trees that can reach up to 30 metres tall.

There are a variety of lime trees, one of the most common ones being the Tilia platyphyilos. Wild lime trees can be found in coppices, bushes, sunny slopes and rocks, along riverbanks in the mountain and submontane areas of Central Europe; it is rarer in Western Europe.

Lime trees are often used to shade town streets, to decorate parks and gardens. Chestnut tree Chestnut trees Castanea sativa are big, m tall trees. Once fecundated, it produces the fruits, i. More specifically, these fruits can be called chestnuts if each husk contains two or three fruits.

Chestnuts ripen in autumn. Depending on the variety, some of which ripen earlier, some later, they can be eaten fresh from early September to early November. Birch Birches Betula pendula come from Europe and the south-east of Asia.

They grow well in sandy and peaty soils. The genus takes its name from the Celtic betu. They love the sun, they grow alone or in small groups in hilly and mountainous sparse woods, along with broad-leaved and coniferous trees.

In the wild state, they can grow even on dry and bare, preferably acid, soils, with enough water, and can tolerate the cold quite well. They are used as ornamental trees for their elegant deportment and the decorative colour of their bark and leaves.Exotic Plants for Temperate Zones By: J.

A. Young There are many plants that are native to tropical locations throughout the world that can be enjoyed in temperate locations in America where there are not extremes in temperatures throughout the heartoftexashop.com: J.

A. Young. Temperate and Tropical Food-plants This page shows some of the major food-plants cultivated in temperate and tropical climates. Climate zones are defined by a combination of factors which include temperature and rainfall as much as latitude.

Plants and animals in the temperate zones respond in various ways to the amount of daylight in hour periods. This response to day length is called photo periodism. It controls many activities, among them the migration of birds, the hibernation of animals, and the flowering of plants.

What animals live in temperate zone

Plants and animals in the temperate zones respond in various ways to the amount of daylight in hour periods. This response to day length is called photo periodism. It controls many activities, among them the migration of birds, the hibernation of animals, and the flowering of plants.

An epiphyte is a plant that grows on another plant, like a tree, and gains nutrients and moisture from the rain, the air around it, and even sometimes debris collected around it.

Epiphytes are commonly found in the temperate zone (like in temperate rainforests). A few examples of epiphytes are moss, and lichen.

Temperate Forest Facts. A wide variety of animals inhabit these regions of temperate forests around the world including mammals, reptiles, birds and numerous different species of insect. Deer, squirrels and wild boars are the most commonly seen mammals in the deciduous forests, along with birds that nest in Average Rainfall (Year): mm - mm.
