As poikilohydric organisms, lichens are capable of storing significant amounts of atmospheric water. Epiphytes that intercept rainfall change the amount and chemical composition of throughfall water, affecting water balance and microclimate of forest ecosystems. The aim of the study was to investigate the differences in the process of changes/increase in the amount of water in three lichen species: Evernia prunastrii, Hypogymnia tubulosa and Platismatia glauca. In the experiment, conducted under laboratory conditions, samples of thalli were wetted with constant doses of water and weighed in order to determine the amount of water storage capacity from simulated rainfall. The studied lichen species differed in terms of process dynamics and values of water storage capacity, probably due to the morphological structure of thalli. Average water retention was the highest in Platismatia glauca (33.58 %), lower in Evernia prunastrii (19.77 %) and the lowest in Hypogymnia tubulosa (15.38 %). Analyzed taxa with larger water storage capacity are also known to be more sensitive to air pollution.

三种地衣物种贮水量的变异性

作为多羟基生物,地衣能够储存大量的大气水。拦截降雨的附生植物会改变贯穿水的数量和化学成分,影响森林生态系统的水平衡和微气候。这项研究的目的是调查三种地衣物种(Evernia prunastrii,Hypogymnia tubulosaPlatismatia glauca)的水量变化/增加过程的差异。。在实验室条件下进行的实验中,用恒定剂量的水润湿Thalli样品并称重,以便根据模拟降雨确定储水量。所研究的地衣物种在过程动力学和储水量方面存在差异,这可能是由于塔利的形态结构所致。平均水分保持率在青萍Platismatia glauca)中最高(33.58%),在Evernia prunastrii(19.77%)中较低,而在小球藻Hypogymnia tubulosa)中最低(15.38%)。还已知具有较大储水能力的已分析生物分类对空气污染更敏感。
