In this regard, it 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 natural sources.

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

Mapping lichen diversity as an indicator of environmental quality. We analyzed the diversity bioindicadpres composition of lichen communities in two fragments, one disturbed and one conserved, of high Andean forest in the “Encenillo” Biological Reserve, Colombia. In this study their therapeutic uses and status as bio indicators of environmental contamination are indicated.

Also, these organisms present antitumor action inhibiting different types of cancer. This abstract may be abridged.

Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.

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. 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. Identifying deviations from naturality of lichen diversity for bioindidations purposes. Sources of error in epiphytic lichen variables mapped as bioindicators: By means of indicator analysis, using the biotypes as units, we found that the biotypes “Yoshimuriella”, “Usnea apothecia “, “Usnea pigmented “, “Parmotrema soredia “, “Lobariella apothecia “, “Sticta green “, “Psiloparmelia”, and “Hypotrachyna soredia ” were statistically indicative of lquenfs conserved forest, whereas the biotypes “Hypotrachyna isidia “, “Usnea pendulous “, “Parmotrema isidia ” and “Heterodermia apothecia ” were representative of the disturbed forest.
