Lichens of Aisen, Southern Chile

Abstract

The lichen mycobiota of Aisen (southern Chile) comprises 319 taxa in 87 genera. All of the species of Menegazzia and Protousnea, previously recorded in Chile, are present in this region. The diversity of biomes, from temperate rainforests −particularly in oceanic zones− to steppe areas, offers an enormous number of macro and microhabitats favorable for lichens. The highest lichen diversity, 56 %, was recorded in an undisturbed locality in Laguna San Rafael National Park. Lichen species diversity is higher in oceanic temperate rainforests than in steppe areas, where the majority of Antarctic lichens (23 %) are registered. Levels of endemism are rather high (26 %) and are due mainly to species of the genera Protousnea, Pseudocyphellaria, Menegazzia, Cladonia, Sticta, Nephroma. Other biogeographical elements in the región's lichen mycobiota are: cosmopolitan (16 %), austral (16 %) and bipolar (13 %). Lichen diversity in Aisen represents about 20 % of the known lichen mycobiota of Chile.

Anatomical, physiological and chemical differences between populations of Pseudocyphellaria flavicans (Hook. f. & Taylor) Vain. from Chile

“…Lichens, in general, are understudied organism, especially in Chile (but see Quilhot et al 2012, Rubio et al 2013, Vargas et al 2013). This study is one of the first ecophysiological studies on Chilean Pseudocyphellaria.…”

Estudio preliminar de la biodiversidad vegetal terrestre en el Estero Walker (Región de Aysén, Chile): utilizando líneas base de proyectos de inversión

“…La clasificación de ellas sólo consideró los grupos tradicionales. Para líquenes y musgos se nombran únicamente aquellas especies más importantes, ya que en Chile aún falta trabajo sistemático en ellos para la Patagonia, especialmente claves de determinación (Villagra et al 2009, Quilhot et al 2012. Por lo anterior, en los censos los musgos fueron considerados en forma colectiva y tratados como una sola especie.…”

Nomenclatural revision and syntaxonomical proposal for wetland peat vegetation in the Valdivian-Magellanian region

“…The goal of a rational syntaxonomy is to address all the floristic variations that can contribute some biogeographical significance, and the participating vascular flora does not offer many possibilities. A greater knowledge on species composition of the moss layer (bryophytes and lichens) of these peatlands would potentially make a more valuable contribution in this regard as indicated by the results of Villagra et al (2009), and particularly by the recent contribution of Quilhot et al (2012).…”
