Epiphytic lichen diversity and its dependence on bark chemistry in the northern Mongolian dark taiga

Edge and land-use effects on epiphytic lichen diversity in the forest-steppe ecotone of the Mongolian Altai

“…The recording of lichens was limited to the lowest 1 m of the tree trunks, because the stems were virtually avoid of lichens above this height. The present study thereby differs from former analyses of the epiphytic lichen diversity in coniferous forests by our group inside (Hauck et al, 2007;Hauck and Javkhlan, 2009) and outside (e.g. Hauck and Spribille, 2005) Mongolia where cover values refer to the lowest 2 m of the trunk surface.…”

Site factors controlling epiphytic lichen abundance in northern coniferous forests

“…Scandinavia (Esseen, 1981;Gauslaa and Holien, 1998;Hilmo et al, 2009;Hilmo, 1994), central Europe Köstner and Lange, 1986), northeastern Asia (Biazrov, 1974;Hauck and Javkhlan, 2009), western Hauck and Spribille, 2005) and eastern (Lang et al, 1980;Schmull et al, 2002) North America. Many other studies include species lists and specifications of preferred substrata, like many studies from Siberia (Makryi, 1990;Plikina, 2003;Sedelnikova and Lashchinskiy, 1991;Urbanavichene, 2001).…”

“…Europe (Harz Mountains, Germany) after Hauck and Runge (2002) Phorophyte: Picea abies Cladonia digitata, C. polydactyla, Hypocenomyce caradocensis, Hypogymnia physodes, Lecanora conizaeoides, Lepraria jackii 2. North-eastern Asia (Western Khentey, Mongolia) after and Hauck and Javkhlan (2009) diversity and biomass are usually higher in the sun-exposed upper canopy than on shady trunk bases (Kermit and Gauslaa, 2001;Lang et al, 1980;McCune et al, 1997). Many lichens of the upper canopy produce UV-B and/or blue light-screening lichen substances or melanins.…”

Bosque de roble o plantación de coníferas, ¿qué prefieren los líquenes epífitos?

“…En lo referente a los líquenes, en nuestra investigación se registran varias especies de la familia Parmeliaceae, como: Hypotrachyna costaricensis (Nyl) Hale, Hypotrachyna osorioi (Hale) Hale, Parmotrema arnoldii (Du Rietz) Hale y Parmotrema simulans (Hale) Hale que son frecuentes en pinos y robles. Esto concuerda con algunos estudios los cuales sugieren que varias especies de la familia Parmeliaceae son tolerantes a la desecación, acidificación de sustratos e incluso a la presencia de material particulado (Hauck y Javkhlan, 2009;Kä-ffer, Ganade y Marcelli, 2009;Llop et al, 2012;Simijaca et al, 2014). Esta familia también es dominante sobre varios forófitos en los bosques del Chaco argentino, donde crecen con exuberancia (Estrabou, 2007).…”
