We sampled 32 “encenillo” trees Weinmannia tomentosa16 in each fragment, using three subsamples per tree at three height levels, for a total of 32 samples trees and 96 subsamples. Relationship between epiphytic lichens, trace elements and gaseous atmospheric pollutants.
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.
The urban area was compared against two bioindicadorse areas with no pollution sources. Epiphytyc lichens as sentinels for heavy metal pollution at forest ecosystems central Italy.

However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.
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.
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.

Lichenology in Latin America: Lobariaceae; Graphidaceae; lichens; biotypes; bioindicators; ecological continuity. 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.
With regard to their medicinal use, lichens are used in the treatment of pulmonary tuberculosis and as vermicide. A new scale for the interpretation of lichen biodiversity values in the Tyrrenian side of Italy. Also, these organisms present antitumor action inhibiting different types of cancer.
