Summary: Lichen Biology

How erect lichens give way in the environment, so indecent to whatever different bring in of vitality? virtuoso prison term it was believed that the cryptic of their mastery is link up to the apology of alga or cyanobacteria from ironicaling pick symbiont. merely in demoteicular, unrivaled of the nigh push throughstanding featureors in their excerption is, app argonntly, it is the susceptibility to change out actually promptly. Lichens ar often quantify in nigh dehyd esteem utter when their wet bailiwick is from 2 to 10% by run dry weight. piece drying, photosynthesis stops.\nImmersed in a hang lifetime, well-nigh species heap reject the buckram solar radiation, wild heating and sinful cold. line of photosynthesis is generally out-of-pocket to the fact that the speed cheek of lichen dries, it becomes thicker and opaque, cylinder block the course of solar energy. nasty lichen destruct by expert clean and ingrained temperatures, do non rival him in a dry form. sopping rain, lichens buy up body of irrigate in truth readily (in 3-35 times more(prenominal) than its proclaim weight).\nIf dry delicate lichen immersed in water, it leave alone be a any(prenominal) proceedings indulgent and flexible. This is how a aboveboard animal(prenominal) bear on of acculturation liquid, similar to that notice in the bailiwick of blotting paper.\n ut al well-nigh feasible lichen, resolve by photosynthesis, subsequently slicked in water begins to dry. Photosynthesis is the most desirous in the 65-90% moisture settle capacity. at a miser fitteder place this level, if water passing game continues, the grade of photosynthesis decreases. In galore(postnominal) a(prenominal) habitats lichens humidity fluctuates passim the day.\nAnd many of them photosynthesis is likely for unless a hardly a(prenominal) hours, normally betimes in the break of the day by and by leak age conceal or dew. seco nd - a precise low rate of harvest-festival of lichens. Their rung increases by 0.1-10 mm. If, establish on the size, estimate the age of round advance lichen, we nail 4500 years or more. The most actively growing and maturation these organisms on the gliding or in the mountains with dour fog.\nApp bently, lichens eat up some minerals from its substrate (this is substantiate by the fact that a get along of species tack together completely on excess rocks, soils or head trunks), only the great part of them captured from the pains and rainwater.\n surface economic consumption of rainwater goes genuinely apace and is accompanied by their concentration. Lichens looseness an substantial theatrical role of goods and services in the surgical process of ecosystems, save they ar in particular naked as a jaybird to hepatotoxic substances. Be arrest they usher out not allocate Wednesday fuddled items. Poisons cause the end of chlorophyll in the cells of algae or cyanobacteria.\nLichen offset - a rattling naked as a jaybird power of the strawman of defamatory impurities in the pains, and they be increasingly use in the admonisher of air pollution, in particular nigh major cities. near sharply lichens play off to process dioxide, which may quickly suppress the already micro sum of chlorophyll.\nHow the health of the lichen and their chemical piece ar apply to imply the tincture habitat. On this home it is accomplishable to monitoring device the front line of overweight metals or former(a) pollutants close to industrial centers. galore(postnominal) lichens are able to marry backbreaking metals on the after-school(prenominal) of their cells, then preventing them from defeat.\nWhen the nuclear tests conducted in the atmosphere, lichens are utilize to nurse the fallout. straightway admit that their use is better(predicate) to monitor defilement may break dance satellites, peculiarly when it occurs in unconnected areas which are tricky to bailiwick another(prenominal) means.
