The community composition of epiphytic macrolichens from two tree species ( and ) was conducted in temperate forests in the Conguillío National Park, Chile. The composition of lichen biota is influenced by phorophyte species, bark pH, and microclimatic conditions. A total of 31 species of macrolichens were found on and . Most of the species showed phorophyte preference, with nine being exclusive to and 10 to . The detrended correspondence analysis (DCA) indicated the formation of three communities: one representing macrolichens growing on and two others growing chiefly on , either with north or south exposure. More work is needed to study the lichen biota of the forests of the Chilean Andes, which are under multiple threats, including clearing and climate change. In order to counteract such risks to native forests and to the biodiversity of the associated epiphytic lichens, conservation plans should be established that consider the factors that influence the composition of the lichen community.
在智利孔古伊利奥国家公园的温带森林中，对两种树种（和）上的附生大型地衣的群落组成进行了研究。地衣生物群的组成受着生植物种类、树皮pH值和小气候条件的影响。在和上共发现了31种大型地衣。大多数物种表现出对着生植物的偏好，其中9种仅见于，10种仅见于。去趋势对应分析（DCA）表明形成了三个群落：一个代表生长在上的大型地衣，另外两个主要生长在上，分别朝向北方或南方。智利安第斯山脉森林的地衣生物群受到包括砍伐和气候变化在内的多种威胁，需要开展更多工作来研究该地衣生物群。为了应对对原生森林和相关附生地衣生物多样性的此类风险，应制定考虑影响地衣群落组成因素的保护计划。
