Effects of the urban environmental conditions on the physiology of lichen and moss

Effects of air pollution on chlorophyll content and morphology of lichens transplanted around a paper industry (Morelia, Mexico)

“…Parameters such as chlorophyll degradation, chlorophyll a/b ratio, photosynthetic rates and chlorophyll fluorescence can detect responses earlier than for total chlorophyll content (Bačkor & Dzubaj 2004;Bačkor et al 2007;Chettri et al 1998;Häffner et al 2001;Picotto et al 2011). On the other hand, several studies recognized that cell membrane damage (Munzi et al 2009;Paoli & Loppi 2008;Paoli et al 2011;Sujetovienė & Galinytė 2016) or changes of the respiration rates (Paoli et al 2015) in the mycobiont are better indicators of pollution stress symptoms than photosynthetic parameters. In the present study, we did not detect a stress response (i.e., reduction of photosynthetic pigments) on the photobiont of both lichen species at the industrial site indicated by chlorophyll content.…”

“…After that, we placed five transplants of each species on each host tree in the study area. Transplants were put in 20 3 20 cm plastic nets with a mesh size of 1 mm 2 (Sujetovienė & Galinytė 2016), at 2 m from ground and then exposed in the direction facing the paper industry. In total, we transplanted 15 samples of each species per each monitoring station (n¼30).…”

Ecophysiological responses of the biocrust moss Syntrichia caninervis to experimental snow cover manipulations in a temperate desert of central Asia

“…MDA, an important product of membrane lipid peroxidation, has been used as an indicator of cell membrane damage under stress conditions (Sujetoviene & Galinyte, 2016). The cell membrane plays an essential role in maintaining the cell interior different from the external medium and it contains receptor for environmental signals (Nicolson, 2014).…”

“…Membrane lipid peroxidation in samples of S. caninervis was estimated using the content of malondialdehyde (MDA) as an indicator of induced oxidative stress (Sujetoviene & Galinyte, 2016). MDA content was determined by thiobarbituric acid based on the colorimetric method described by Choudhury and Panda (2005).…”

Moss-indoor vertical greenery system design protocol: Using moss as an indoor vertical greenery system in the tropics

“…3,32 In contrast, carrier systems are able to host a greater diversify of plants, including groundcovers, shrubs, ferns, grasses, sedges and even mosses. 35 Such systems are commonly termed ‘living wall systems’ (LWSs). Vertical greenery is the result of greening with plants, either rooted in the ground, on the wall material itself, or in modular panels attached to the facade to cover the building with plants.…”
