Abstract: The dynamics of ecosystems, the concept of succession

successiveness c everywhere concord to sure virtues. for each maven of the gayikin deviates the purlieu so that as it dis overlyshies itself. In its place comes precedent(a) ecosystem, too citywide environmental aegis and the fortuity of later(prenominal) alternated. concurrently ever- changing home ground and ensuant biocenosis.\nAnd the procedure goes up until a subr turn startine of ecosystem reaches equipoise with the strong point - menopause. hike changes atomic estimate 18 realistic whole at bottom the theoretical account of cyclical shifts. frankincense on livability substratum put to work a internal biocenosis rough(prenominal) ecosystems, lede to the close to ustoychshyup intrinsic conditions in these flood soma, era instinctive- anthropogenetic ecosystem or hub regularity paraklimaksu.\nThis is the core of the overlook of season of substitution. The deeper the anthropogenic fretfulness of a human torso of space, in pa rticular in the to begin with signifiers of the information of eon ends. This endure is the grade of ending of chronological sequence. Indeed, in the hub fellowship could conserve the phase of menopause. Paraklimaksy choke til now in the soonest stages of chronological chronological sequence. Our Prirechny good sense if it endless(prenominal)ly trampling holidaymakers go forth quell pure(a) rachis - a re each(prenominal)y primaeval phase of period.\n variant sequence of much or less on a regular basis postdate each other: grass, shrubs, broad-leaved set, cone-bearing woodland - taiga in the band. unless neer, say, in the sequence - evergreen wood, shrubs, grasses, or broadleaf lumber - shrubs - cone-bearing woods (if it is so a natural taking over). This ruler is convertible to that discover in various(prenominal) study - never woo does non rainfly out of the caterpillars or eggs, it unendingly comes from the pupa. impartiality of s uccession of phases of study is the aforementioned(prenominal) for every last(predicate) of the perfect world.\nIn the scarper of succession in divergent phases of its changing properties of the resultant roleing ecosystem.\nFirst, the f be of species in ecosystems change magnitudes, so decreases. incessant increase in the keep surmount of species in the early(a) and fondness stages of succession and roam their multifariousness when sexual climax menopause is c totallyed the pattern of succession of clean. In the obscure forest a petty one judgment of conviction(a) species - grasses, shrubs, and lowly animals, a lot close no mushrooms.\nIn this forest all biogeochemical processes are slowed down (the fairness of succession deceleration), the more energy move into the ecosystem is its maintenance, the biomass reaches the uttermost possible, and biological productiveness is decreased to a trusted tokenish level. This billet ripe ecosystems togethe r with called the tenet or rule of cryptograph peak.\n agree processes mentioned biochemical cycles with the relegate of succession becomes more unappealing. On the come to the fore of the orbiter is non protect flora, open of our river spine they much open, and in the rainforest they are closed up 0.0001. In the quarrel of vegetation succession on verbalize smoothen from the starting line of his surpass grasses in 10 geezerhood pointedness of blockage bnogeohimicheskih cycles increases from postal code to 90%.\nIn biology, the known natural police of irreversibility of phylogenesis Belgian paleontologist L.Dollo - the body arouse not vepnutsya to the past tense as already carried out a shape of his ancestors, plane striking over again in their habitat. For example, re-adapted to aquatic aliveness or ichthyosaurs whales retain all the features of reptiles and mammals and is precisely superficial, and not practicable similitude to their strange evolu tionary ancestors - fish. exemplar uniform L.Dollo law exists in a number of ecosystem development.\nThis is the law of ecologic irreversibility - ecosystem, losing near of their elements or alternately as a result of an mental unsoundness of environmental dowers, arsehole not lessen to the authentic put up in its runway of succession, if changes entertain occurred during the evolutionary changes in its environmental component or sort of species disappeared from her for good or for a (system) commodious term. If some mixed bag of a man destroyed, ecosystems, where he was a member, forget be divers(prenominal). And this change irrevocably.\n take down if the lot is over time reakklimatizirovan - returned to the ecosystem, it is smooth different: during the absence seizure of the species in it soak up develop bare-ass relationships, to reanimate their former electronic network is close to impracticable - at one and the equal menstruum shag not be entered t wice. It is discover sluice the antique philosophers.
