orderlies forests - are animals capable of the actions to clean their own environment.And even if their behavior is conditioned by instincts developed during many years of evolution, yet one should not underestimate their role in the ecosystem of the region.But who are they?
If we talk about the animals that live on the territory of the Russian Federation, it should be noted three major groups.This bird, ants and wolves.Despite strong external differences, all of them are great defenders of the environment.
role of birds in the forest ecosystem
By their nature, all the birds - the orderlies forests.This is due to the fact that they feed on insects, which, in turn, are major pests.Judge for yourself, because it is the insects eat the leaves of trees, destroy the wood and bark, as well as carry various infectious diseases.
Belly beetles and caterpillars, birds reduce their numbers, which reduces damage to the environment to a minimum.This allows the food chain to achieve harmony, which is so necessary for normal growth of the forest.
But though all the birds - the orderlies forests, yet there are species that do their job better than anyone else.For example:
- Woodpecker - is the main doctor in the forest, because it is able to pick out pests straight from the tree trunk.In addition, banging on it with its beak, it causes insects to crawl out of the asylum, thereby making them vulnerable to other hunters.
- pastor actively hunting for locusts.That is why this bird - as a welcome guest not only in forests, but also in orchards.
- Starlings - is the fastest orderlies forests.According to rough estimates of scientists, they may catch up to 400 bugs in a single day.
Ants - small forest guards
But not all insects are harmful to the environment.There are those who seek to protect it from pests every way.Everyone has heard about them, and yet not many people know why ants - orderlies forests.
The reality is quite simple.Ants are destroying almost all insects that dare to crawl on their territory.However, they can easily cope with the enemy, which is superior to them both in size and physical strength.And all because of ants - a team able to act as a single mechanism.
In addition, they use their building debris, thereby clearing the forest.If you believe the experts, the five anthills enough to keep clean an area of one hectare.
Wolves - predatory orderlies forests
Many are afraid of wolves, and the fact there are good reasons.These predators always hunting hounds, and not disdain any prey.Yet they are called orderlies forests.You want to know why?
First of all wolves, like all predators, feed on dead animals.Through this forest so little drops, which reduces the risk of various types of diseases.In addition, wolves prefer to kill the weak and sick animals, not allowing them to continue their family.This natural mechanism allows to improve the gene pool of the species and increase the chances of survival.
Besides Wolves control the number of herbivores.A case where in America in one of the states were exterminated almost all the wolves.Subsequently, the population of herbivores so increased that the pastures were unable to grow with new grass.The poor animals were dying of hunger, and their bodies have become hotbeds of serious diseases.
