“…DR5; Loader et al, 2016). Many studies on carbon isotope composition of mosses concluded that moisture availability exerts a critical influence (Rice and Giles, 1996;Price et al, 1997;Ménot and Burns, 2001;Loisel et al, 2009), although other studies indicated potential influence of temperature, probably due to intrinsic relation between temperature and moisture-related environmental factors (e.g., Ménot and Burns, 2001;Moschen et al, 2011). Other influencing factors include CO 2 concentration (White et al, 1994) and recycled CH 4derived CO 2 (Price et al, 1997 (Ménot-Combes et al, 2002;Zanazzi and Mora, 2005).…”
