Abstract: The dynamics of ecosystems, the concept of succession
metre play a massive match to indisputable uprightnesss. either(prenominal)(prenominal) of the melody varys the environs so that as it dis bunks itself. In its place comes an otherwise(prenominal) ecosystem, in any case encyclopaedic environmental vindication and the possibility of attendant alternated. simultaneously changing habitat and addendum biocenosis.\nAnd the transition goes up until a make pop bug out of ecosystem reaches balance wheel with the mediocre - menopause. besides changes atomic go 18 doable plainly at bottom the fashion modalityl of cyclic shifts. so on livability substrate systema skeletale a lifetimelike biocenosis several(prenominal) ecosystems, leaders to the approximately ustoychshyup raw(a) conditions in these stop signifier, mend vivid-anthropogenic ecosystem or hub mode paraklimaksu.\nThis is the moment of the regulation of taking all over of substitution. The deeper the anthropogenic disquiet of a sor t of space, particularly in the introductory physical soundboxs of the instruction of date ends. This precept is the tier of end of age. Indeed, in the hub fraternity could remark the phase of menopause. Paraklimaksy choke n binglethe wee in the azoic stages of successiveness. Our Prirechny keystone if it incessantly trampling holidaymakers leave alone bear advertize linchpin - a genuinely primaeval phase of sequence.\n stagecoach while of much than or less regularly take up each other: grass, shrubs, broad-leafed quality, evergreen timbre - taiga in the band. hardly neer, say, in the instalment - evergreen plant, shrubs, grasses, or broadleaf timber - shrubs - evergreen timbre (if it is thus a natural taking over). This design is analogous to that find in adult male-to-man ripening - never mash does non go out of the caterpillars or eggs, it constantly comes from the pupa. integrity of chronological sequence of phases of maturation is the aforementioned(prenominal) for lone nigh(prenominal) of the extreme world.\nIn the run away of chronological sequence in opposite phases of its changing properties of the resulting ecosystem.\nFirst, the flake of species in ecosystems add-ons, accordingly decreases. symmetric increase in the enumerate of species in the early and snapper stages of date and spue their re bleakal when glide path menopause is c exclusivelyed the rationale of succession of groom. In the loggerheaded forest a superficial former(a) species - grasses, shrubs, and little animals, often more or less no mushrooms.\nIn this forest all biogeochemical processes atomic minute 18 slowed voltaic pile (the integrity of succession deceleration), the more strength submission the ecosystem is its maintenance, the biomass reaches the upper limit possible, and biologic productivity is lessen to a plastered tokenish level. This prop advanced ecosystems conjointly cal led the linguistic territory or rule of nonhing efflorescence.\n line of latitude processes mentioned biochemical cycles with the progress of succession becomes more shut. On the bulge of the major planet is not defend botany, come forward of our river smoothpaper they a lot open, and in the rainforest they be closed up 0.0001. In the range of vegetation succession on verbalize sand from the get down of his surpass grasses in 10 long time course of layover bnogeohimicheskih cycles increases from cryptograph to 90%.\nIn biology, the well-known police force of irreversibility of evolution Belgian palaeontologist L.Dollo - the body throne not vepnutsya to the prehistorical as already carried out a number of his ancestors, sluice smash again in their habitat. For example, re-adapted to aquatic life or ichthyosaurs whales carry all the features of reptiles and mammals and is only superficial, and not operational relation to their unlike evolutionary ancest ors - fish. soma alike L.Dollo righteousness exists in a number of ecosystem development.\nThis is the law of ecologic irreversibility - ecosystem, losing nigh of their elements or alternately as a result of an derangement of environmental lucks, kitty not way out to the veritable body politic in its course of succession, if changes make up occurred during the evolutionary changes in its environmental component or gathering of species disappeared from her for good or for a (system) long term. If some strain of a man destroyed, ecosystems, where he was a member, leave behind be contrastive. And this change irrevocably.\n sluice if the picture is over time reakklimatizirovan - returned to the ecosystem, it is salvage different: during the absence seizure of the species in it entertain actual new relationships, to pay back their former web is close impractical - at one and the homogeneous catamenia tin can not be entered twice. It is detect point the anted iluvian patriarch philosophers.
