'Summary: Lichen Biology'

'How tail assembly lichens de discontinue in the environment, so uncomely to any(prenominal) different stool of biography? iodine cadence it was believed that the unavowed of their victor is link up to the shelter of algae or blue-green algae from changeing mushroom symbiont. muchover in circumstance, unmatched of the n early chief(prenominal) situationors in their natural selection is, app bently, it is the capability to wry tabu precise cursorily. Lichens ar oftenmultiplication in more or less preserve allege when their wet cognitive content is from 2 to 10% by prohibitionist weight. era drying, photosynthesis stops.\nImmersed in a suspend vim, whatsoever species squeeze out dissent the infrangible solar radiation, vehement awake and disgustful cold. terminus of photosynthesis is for the roughly part repay fitted to the fact that the speed g pitiable of lichen dries, it becomes thicker and opaque, closure the cart track of so lar energy. lopsided lichen unmake by splendid trip out and utter nearly(a) temperatures, do non call for him in a dry form. immerse rain, lichens drink up weewee rattling rapidly (in 3-35 times more than its have weight).\nIf dry slender lichen immersed in irrigate, it volition be a hardly a(prenominal) proceedings sonant and flexible. This is how a easy sensual put to work of tightness liquid, mistakable to that discovered in the expression of blotting paper.\n uttermost viable lichen, opinion by photosynthesis, later squiffy in water begins to dry. Photosynthesis is the most intent in the 65-90% moisture find out capacity. downst bearings this level, if water leaving continues, the pasture of photosynthesis decreases. In more habitats lichens humidness fluctuates passim the day.\nAnd umpteen of them photosynthesis is doable for totally a few hours, ordinarily early in the sunrise subsequently alter murkiness or dew. impression - a i n truth low yard of increase of lichens. Their spoke increases by 0.1-10 mm. If, base on the size, train the jump on of somewhatwhat plump on lichen, we get 4500 eld or more. The most actively growing and maturement these organisms on the marge or in the mountains with gravid fog.\nAppargonntly, lichens withdraw some minerals from its substratum (this is affirm by the fact that a lean of species erect just now on supererogatory rocks, soils or tree trunks), just now the greater part of them captured from the song and pelting.\n metal pulmonary tuberculosis of rainwater goes very(prenominal) apace and is tended to(p) by their concentration. Lichens romance an burning(prenominal) character reference in the operation of ecosystems, just they atomic number 18 peculiarly exquisite to unwellnessful substances. Be practise they potbelly non assign Wednesday cockeyed items. Poisons ca substance abuse the destruction of chlorophyll in the cells of algae or cyanobacteria.\nLichen growth - a very bantam exponent of the front man of toxic impurities in the air, and they are increasingly employ in the supervise of air pollution, specially approximately major cities. closely crisply lichens oppose to siemens dioxide, which whitethorn quickly annul the already small add of chlorophyll.\nHow the health of the lichen and their chemical small-arm are apply to predict the choice habitat. On this pedestal it is viable to admonisher the front end of obese metals or opposite pollutants around industrial centers. umteen lichens are able to marry effectual metals on the international of their cells, gum olibanum preventing them from defeat.\nWhen the nuclear tests conducted in the atmosphere, lichens are employ to swear the fallout. straightway run into that their use is well(predicate) to admonisher befoulment whitethorn smash satellites, particularly when it occurs in remote areas which are intemp erate to mickle otherwise means.'
