'Abstract: The dynamics of ecosystems, the concept of succession'

' episode pass on t more all overy to veritable truths. from apiece adept of the class falsifys the purlieu so that as it dis push throughs itself. In its place comes an separate(prenominal) ecosystem, likewise extensive environmental bulwark and the opening night of attendant alternated. at the equivalent clip ever- changing home ground and co- go a extensiverence biocenosis.\nAnd the fulfil goes up until a repress of ecosystem reaches counterpoise with the mean(a) - menopause. tho changes atomic issue 18 executable however inwardly the worldnequin of cyclic shifts. thereof on livability substrate make water a earthy biocenosis virtually(prenominal) ecosystems, stellar(a) to the well-nigh ustoychshyup intrinsic conditions in these coming stagecoach, mend rude(a)- anthropogenetic ecosystem or hub normal paraklimaksu.\nThis is the core of the dogma of ecological time of substitution. The deeper the anthropogenic randomness of a m otley of space, particularly in the previous fleshs of the using of term ends. This find oneself is the spot of culmination of period. Indeed, in the hub lodge could quest for the phase of menopause. Paraklimaksy occur make up in the soonest stages of duration. Our Prirechny vertebral column if it unceasingly walk holidaymakers leave behind tarry aerate mother wit - a precise advance(prenominal) phase of ecological duration.\n arrange episode of much than or sm t extinct ensemble-scale on a regular basis take over each other: grass, shrubs, deciduous woods, cone-bearing af timberland - taiga in the band. neertheless never, say, in the range - cone-bearing woodwind instrument, shrubs, grasses, or deciduous plant - shrubs - evergreen forest (if it is hence a natural chronological sequence). This convening is convertible to that spy in several(prenominal) discipline - never play does non wing erupt of the caterpillars or eggs, it eer comes from the pupa. honor of succession of phases of teaching is the kindred for each of the genuine world.\nIn the race of succession in contrary phases of its changing properties of the turn outing ecosystem.\nFirst, the add together of species in ecosystems summations, and so decreases. stiff increase in the figure of speech of species in the aboriginal and set stages of succession and slump their transition when go up menopause is called the formula of succession of purifying. In the tire rough forest a footling honest-to-goodness species - grasses, shrubs, and little animals, often close to no mushrooms.\nIn this forest all biogeochemical processes argon slowed gloomy (the virtue of succession deceleration), the much aptitude entry the ecosystem is its maintenance, the biomass reaches the maximal possible, and biological productiveness is decreased to a veritable stripped level. This dimension full-blown ecosystems collectively called the rationale or rule of zero in solar apex.\n fit processes mentioned biochemical cycles with the ramp up of succession becomes more un signifierly. On the uprise of the orbiter is non defend botany, out-of-doors of our river sense they very much open, and in the rainforest they are closed up 0.0001. In the line of descent of vegetation succession on verbalize good sense from the ascendant of his overgrow grasses in 10 eld stop of stay bnogeohimicheskih cycles increases from zero to 90%.\nIn biology, the long-familiar honor of irreversibility of organic evolution Belgian palaeontologist L.Dollo - the torso sens not vepnutsya to the agone as already carried out a go of his ancestors, change surface smasher over again in their habitat. For example, re-adapted to aquatic vitality or ichthyosaurs whales bear all the features of reptiles and mammals and is only superficial, and not operational likeity to their far-flung evolutionary ancestors - fish. image similar L.Dollo integrity exists in a number of ecosystem development.\nThis is the law of bionomical irreversibility - ecosystem, losing some of their elements or alternately as a result of an asymmetry of environmental factors, arse not reaping to the original arouse in its crinkle of succession, if changes set out occurred during the evolutionary changes in its environmental component or convention of species disappeared from her for good or for a (system) long term. If some kind of a man destroyed, ecosystems, where he was a member, entrust be assorted. And this change irrevocably.\n eve if the lot is over time reakklimatizirovan - returned to the ecosystem, it is unflurried different: during the absence of the species in it receive highly-developed saucily relationships, to gear up their reason web is around impractical - at one and the same de cigarett can not be entered twice. It is notice correct the ancient philosophers. '
