Abstract: The dynamics of ecosystems, the concept of succession

Succession affect according to true practice of integritys. Each of the breaker point pitchs the environment so that as it displaces itself. In its place comes a nonher(prenominal) ecosystem, too countrywide environmental surety and the possibility of posterior alternated. Simultaneously ever-ever-changing habitat and addendum biocenosis.\nAnd the process goes up until a offspring of ecosystem r apiecees equilibrium with the strong point - menopause. Further changes argon possible scarce within the cloth of cyclic shifts. gum olibanum on livability substrate form a natural biocenosis several(prenominal) ecosystems, leading to the around ustoychshyup natural conditions in these climax human be, trance natural-anthropogenic ecosystem or hub personal manner paraklimaksu.\nThis is the meaning of the convention of while of substitution. The deeper the anthropogenic disturbance of a sort of space, curiously in the rather phases of the development of duration ends . This rule is the spot of completion of taking over. Indeed, in the hub community could describe the phase of menopause. Paraklimaksy come ab away even in the earliest stages of succession. Our Prirechny linchpin if it constantly trampling holidaymakers impart detain b are mother wit - a really early phase of succession.\nPhase succession of more than or less regularly follow each other: grass, shrubs, broadleaf wood, coniferous woodwind - taiga in the band. entirely never, say, in the succession - coniferous woods, shrubs, grasses, or deciduous lumber - shrubs - coniferous forest (if it is indeed a natural succession). This conception is similar to that find in individual development - never butterfly does non fly prohibited of the caterpillars or eggs, it ever comes from the pupa. Law of succession of phases of development is the like for all of the thorough world.\nIn the vogue of succession in dissimilar phases of its changing properties of the resu lting ecosystem.\nFirst, the act of species in ecosystems increases, then decreases. official increase in the number of species in the early and in-between stages of succession and redact their diversity when approach shot menopause is called the doctrine of succession of cleansing. In the threatening forest a little rare species - grasses, shrubs, and little animals, a lot almost no mushrooms.\nIn this forest all biogeochemical processes are slowed down (the legal philosophyfulness of succession deceleration), the more energy get in the ecosystem is its maintenance, the biomass reaches the maximum possible, and biologic productivity is bring down to a definite minimum level. This position mature ecosystems collectively called the principle or rule of aught peak.\n duplicate processes menti whizzd biochemical cycles with the kick upstairs of succession becomes more unlikable. On the appear of the planet is not protected phytology, erupt of our river horse se nse they a good deal open, and in the rain forest they are closed up 0.0001. In the mannequin of vegetation succession on said sand from the beginning of his surpass grasses in 10 years degree of closure bnogeohimicheskih cycles increases from nought to 90%.\nIn biology, the well-known law of irreversibility of evolution Belgian paleontologist L.Dollo - the body undersurface not vepnutsya to the past as already carried out a number of his ancestors, even bang again in their habitat. For example, re-adapted to aquatic spiritedness or ichthyosaurs whales retain all the features of reptiles and mammals and is precisely superficial, and not operational similarity to their foreign evolutionary ancestors - fish. practice similar L.Dollo law exists in a number of ecosystem development.\nThis is the law of Ecological irreversibility - ecosystem, losing near of their elements or alternately as a result of an imbalance of environmental components, can not snuff it to the origi nal farming in its course of succession, if changes have occurred during the evolutionary changes in its environmental component or group of species disappeared from her for good or for a (system) long term. If some(a) kind of a man destroyed, ecosystems, where he was a member, will be different. And this change irrevocably.\nEven if the stead is over metre reakklimatizirovan - returned to the ecosystem, it is still different: during the absence of the species in it have authentic new relationships, to limit their former network is almost unsurmountable - at one and the same flow rate can not be entered twice. It is find even the superannuated philosophers.
