“…In this study, the larger mortality of evergreen N. dombeyi compared to deciduous N. pumilio, which was leafless at the time of the eruption, may provide indirect evidence that ash effects on foliage contributed to mortality. However, other mechanisms, such as acid deposition, are possible as well (e.g., Tognetti et al 2012); although Nelson and Wheeler (2016) did not observe evidence of chemical damage in their study of lichens in our plots at Caulle.…”

“…In the Southern Volcanic Zone (SVZ) in South America, the direct impact of Puyehue volcano eruption, in 2011 was studied using lichens by Bubach et al [4,13] and by Nelson and Wheeler [14] in areas up to 100 km from the crater. Also Conti et al [15] evaluated the effects of the impact at 1600 km approximately from the volcano, in Tierra del Fuego, Argentina.…”

The atmospheric pollution associated with the volcano Copahue activity was evaluated by analyzing the concentration of 33 elements including heavy metals in lichens. Fruticose thalli were collected between 7 and 18 km from the volcano crater, comprising a geothermal zone. Analytical data and geographic parameters were evaluated by Principal Component Analysis. Enrichment Factors was also calculated from elemental concentrations in the lichens. The Principal Components Analysis grouped the observations corresponding to the lichen samples in relation to the volcano crater distance, the thermal areas and the direction of the prevailing winds. The less impacted area by volcanic products presented a lower concentration of toxic elements (S and Hg) and a higher concentration of biological elements (Ca, K, Mg and Mn) than the other areas. All studied sites showed S and Se enrichments, even in the most distant areas from the volcano crater. The S concentrations in lichen recorded in areas of volcanic activity were higher for the volcanic complexes: Copahue-Caviahue and Puyehue-Cordón-Caulle (2800-12000 μg/g) than those reported for the rest of the world (600-2800 μg/g).

Se presentan los resultados de las evaluaciones de la liquenobiota saxícola del nevado Pastoruri (Cordillera Blanca, departamento de Áncash) realizadas en los meses de septiembre de los años 2011 y 2012. La composición de la liquenobiota fue de 28 especies, agrupados en 19 géneros y 14 familias. Las familias Lecanoraceae, Parmeliaceae y Teloschistaceae presentaron el mayor número de géneros, mientras que los géneros Buellia, Lecanora y Umbilicaria registraron mayor riqueza de especies. Los líquenes de biotipo crustáceos fueron los dominantes (61% del total), seguido por los foliosos (32%) y fruticosos (7%).
