The results would indicate homogeneity in the air in the study areas, even though the areas chosen have remarkable differences in ground use urban area vs. According to the results, the areas evaluated do not present differences in the values of IAP neither in lichen diversity. In the urban area there is a growing human population and fixed and movile sources of pollutants. Biodiversity of epiphytic lichens and heavy metal contents of Flavoparmelia caperata thalli as indicators of temporal variations of air pollution in the town of Montecatini Terme central Italy.
This type of organism has the capacity to synthesize more than secondary metabolites. In relation to their biological activity, lichens are used as antioxidants to delay cell aging; antiviral compound against the Acquired Immunodeficiency Disease Syndrome and the Human Papilloma Virus, and antibacterial compound used in Gram positive bacteria inhibition.
Also, these organisms present antitumor action inhibiting different types of cancer. All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License.
Up to date, between 17, and 20 thousand variants have been identified, including 1, lichenicholous fungi. Use of lichen biotypes as bioindicators of perturbation in fragments of high Andean forest “Encenillo” Biological Reserve, Colombia.
Measurements for terrestrial vegetation. In this regard, it is estimated that a significant number of substances will bioindiicadores discovered in the coming years, taking into consideration that only a low proportion has been analyzed from available natural sources. In conclusion, a protocol using biotypes instead of species can be implemented by non-specialists to monitor and quickly evaluate the conservation of these Andean forests.
Biodiversity of epiphytic lichens and air pollution in the town of Siena Central Italy.

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. The assumption of the method is that the frequency of species will be reduced when the pollutants increase.

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. Reliabiliy of different sampling densities for estimating and mapping lichen diversity in biomonitoring studies. With regard to their medicinal use, lichens are used in the treatment of pulmonary tuberculosis and as bioondicadores.
Ecological parameters like diversity, richness and equitativity were determined. Methods and basilenes using lichens.
