A new scale for the interpretation of lichen biodiversity values in the Tyrrenian side of Italy. By means of bioindiccadores analysis, using the biotypes as units, we found that the biotypes “Yoshimuriella”, “Usnea apothecia “, “Usnea pigmented “, “Parmotrema soredia “, “Lobariella apothecia “, lquens green “, “Psiloparmelia”, and “Hypotrachyna soredia ” were statistically indicative of the conserved forest, whereas the biotypes “Hypotrachyna isidia “, “Usnea pendulous “, “Parmotrema isidia ” and “Heterodermia apothecia ” were representative of the disturbed forest.

EVALUACIÓN DE LOS LÍQUENES COMO BIOINDICADORES DE LA CONTAMI by eden sierralta on Prezi

A retrospective study using epiphytic lichens as biomonitors of air quality: In this regard, bioindicadoree is estimated that a significant number of substances will be discovered in the coming years, taking into consideration that only a low proportion has been analyzed from available lqunees sources. Also, these organisms present antitumor action inhibiting different types of cancer. The lichen specimens sampled, in the disturbed and in the conserved forest, corresponded to 54 species, with the genera Parmotrema specimens, 5 speciesUsnea specimens, 7 speciesHypotrachyna 79 specimens, 7 speciesPhyllopsora 63 specimens, 2 speciesand Sticta 49 samples, 6 species most representative.

Kluwer Academic Publishers, Netherlandspp. A large quantity of natural products and biomolecules have been isolated and characterized from plants, lichens, fungi and sea organisms; in particular, more than thousand secondary metabolites have been extracted from plants.
