A new scale for the interpretation of lichen biodiversity values in the Tyrrenian side of Italy. The lichen specimens sampled, in the disturbed and in the conserved forest, corresponded to 54 species, with the bioindjcadores 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 bioindicaadores will be reduced when the pollutants increase. Identifying deviations from naturality of lichen diversity for bioindidations purposes.
Biooindicadores between epiphytic lichens, trace elements and gaseous atmospheric pollutants. How to cite this article. By means of indicator analysis, using the biotypes as units, we found that the biotypes “Yoshimuriella”, “Usnea apothecia “, “Usnea pigmented lsuenes, “Parmotrema soredia “, “Lobariella apothecia “, “Sticta 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.
According to the results, the areas evaluated do not present differences in the values of IAP neither in lichen diversity.

Biodiversity of epiphytic lichens and air pollution in the town of Siena Central Italy. 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. With regard to their medicinal use, lichens are used in the treatment of pulmonary tuberculosis and as vermicide. 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.
Kluwer Bioindjcadores Publishers, Netherlands, bioinricadores. 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. Use of lichen biotypes as bioindicators of perturbation in fragments of high Andean forest “Encenillo” Biological Reserve, Colombia. A retrospective study using epiphytic lichens as biomonitors of air quality: Monitoring with lichens-Monitoring lichens P.
Mapping lichen diversity as an indicator of environmental quality.
On the other hand, lichens are used as bio monitors of environmental contamination. No warranty is given about the accuracy of the copy. Las formaciones vegetales en la provincia de San Luis. We analyzed the diversity and composition of lichen communities in two fragments, one disturbed and one conserved, of high Andean forest in the “Encenillo” Biological Reserve, Colombia. Biodiversity of epiphytic bioindicaodres and heavy metal contents of Flavoparmelia caperata thalli as indicators of temporal variations of air pollution in the town of Montecatini Terme central Italy.
Octubre de ; Aprobado: Wiley, New York, pp. We lquened 32 “encenillo” trees Weinmannia tomentosa16 in each fragment, using three iboindicadores 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. In this study their therapeutic uses and status as bio indicators of environmental contamination are indicated.
This type of organism has the capacity to synthesize more than secondary metabolites. Lichenology in Latin America: Kluwer Academic Publishers, Netherlandspp.

Monitoring lichens as indicators of pollution. Measurements for terrestrial vegetation. Lobariaceae; Graphidaceae; lichens; biotypes; bioindicators; ecological continuity. Ecological parameters like diversity, richness and equitativity were determined. Users should refer to the original published version of the material for the full abstract. Atlas del Gran Chaco Sudamericano. Cluster analysis and bioinicadores multidimensional scaling of the 32 samples trees separated the two fragments based on lichen biotype composition.
The urban area was compared against two control lquebes with no pollution 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. This abstract may be abridged. The lichen comunity was evaluated in Juana Koslay City, San Luis Argentinaas environmental pollution bio-indicators. In the urban area there is a growing human population and fixed and movile sources of bioindicadored.
Up to date, between 17, and 20 thousand variants have been identified, including 1, lichenicholous fungi. Epiphytyc lichens bioindicadoores sentinels for heavy metal pollution at forest ecosystems central Italy. Also, they are used to control fevers, relieve pain, and as expectorant, among others.
