Also, these organisms present antitumor action inhibiting different types of cancer. Monitoring lichens as indicators of pollution. Reliabiliy of different sampling densities for estimating and mapping lichen diversity in biomonitoring studies.

The assumption of the method is that the frequency of species will be reduced when the pollutants increase. Up to date, between 17, and 20 thousand variants have been identified, including 1, lichenicholous fungi. The urban area was compared against two control areas with no pollution sources. A new scale for the interpretation of lichen biodiversity values in the Tyrrenian side of Italy.

No warranty is given about the accuracy of the copy. Methods and basilenes using lichens. 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.

Likewise, they are used in the field of cosmetics and in pharmaceutical preparations. Buenos Aires, 95 pp. Wiley, New York, pp. Measurements for terrestrial vegetation. 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 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 lwuenes values of IAP neither in lichen diversity.

In the urban area there is a growing human population and fixed and movile sources of pollutants. Studies on lichens and atmospheric pollution in Argentina.

Octubre de ; Aprobado: Sources of error in epiphytic lichen variables mapped as bioindicators: Cluster analysis and non-metric multidimensional scaling of the 32 samples trees separated the two fragments based on lichen biotype composition. This type of organism has the capacity to synthesize more than secondary metabolites.

Relationship between epiphytic lichens, trace elements and gaseous atmospheric pollutants.

We analyzed the diversity and composition of lichen communities in two fragments, one disturbed and one bioindicadoores, of high Andean forest in the “Encenillo” Biological Reserve, Colombia.

Ediciones Omega, Barcelona, pp. Also, they are used to control fevers, relieve pain, and as expectorant, among others.

The lichen comunity was evaluated in Juana Koslay City, San Luis Argentinaas environmental pollution bio-indicators. In this study their therapeutic uses and status as bio indicators of environmental contamination are indicated. In relation to their biological activity, lqhenes 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.
