Litjeroff R., Lima L. & Prieri B. (2009): Uso de líquenes como bioindicadores de contaminación atmosférica en la ciudad de San Luis, Argentina, Revista Internacional de Contaminación Ambiental, 25(2): 111–120

[in Spanish with English abstract: ] Air qualtiy was assessed in San Luis City by using lichens as bioindicators. Six sites in San Luis City and one site in a control area, juana Koslay, a small town six kilometers to the East, were evaluated by using the Index of Atmospheric Purity (IAP) which measures indirectly the coverage of lichens in the sampling zone and directly the diversity of species. Shannon (H), equity (J) and richness (S) indexes were also measured. The lowest IAP were detected in … URL EN Read more...

Fontecha A. & Burgaz A.R. (2018): Uso de los líquenes como bioindicadores de la calidad del aire: estado de la Ciudad Universitaria (Madrid, España), Botanica Complutensis, 42: 57–68

(Use of lichens as bioindicators of air quality: status of Ciudad Universitaria (Madrid, Spain). [in Spanish with English abstract: ] Sampling 11 plots on Pinus phorophytes in Ciudad Universitaria and 3 control plots in Monte de El Pardo the effects of pollution in Ciudad Universitaria are studied. Although the indexes of diversity and atmospheric quality show the absence of diversity loss, composition reveals the marked effects of fires, eutrophication and bark basification. The lichen flora … EN Read more...

(2014): Uso de organismos vegetales no vasculares como indicadores de contaminación atmosférica urbana (Tunja, Boyacá, Colombia) [Use of non vascular plant organisms as indicators of urban air pollution (Tunja, Boyacá, Colombia)], Acta Biológica Colombiana, 19(2): 221–232

[in Spanish with English abstract: ] Lichens and bryophytes are useful organisms in air quality determination. In the city of Tunja (Boyacá, Colombia), is evident the lack of green areas by the increase of building, which contributes to the detriment of the atmospheric purity making unhealthy conditions to the citizens and habitats and population reduction of cryptogamic plants. Using the Index of Atmospheric Purity (IAP) we identified the greater influence air pollutants areas. Parmotrema austrosinense … EN Read more...

Llano G.A. (1956): Utilization of lichens in the arctic and subarctic, Econ. Bot., 10(4): 367-392

The principal economic importance of lichens lies in their providing sustenance for hundreds of thousands of reindeer in circumpolar regions, animals upon which the Eskimos, Lapps and other Far North peoples depend for food and clothing. Industrially many of them still furnish raw materials for the dyeing and cosmetic industries, and in past times some of them served for brewing, distilling and medicine. During World War II, the reindeer industry contributed substantially to the Soviet war effort. … EN PDF Read more...
