Sedge replacement by grasses accelerates litter decomposition and decreases organic matter formation in alpine meadow soils

Abstract: The dominance of sedges in Tibetan meadows is decreasing with the increasing abundance of grasses, mainly due to anthropogenic activities, nitrogen deposition, and climate warming. We investigated the effects of this vegetation shift on litter decomposition (in the field), mineralization to CO2, and litter carbon (C) incorporation into microorganisms (under laboratory conditions) under sedges and grasses at community and species levels. Litter C incorporation into soil organic carbon (SOC) was estimated using … Show more

“…Owing to global warming, the Qinghai‐Xizang Plateau has gradually become arid (Gao et al., 2015 ; Xue et al., 2017 ). Deeper plants such as forbs and grasses, which have greater drought tolerance (You et al., 2014 ), are replacing shorter‐rooted sedges in alpine meadows (Liu et al., 2018 ; Mou et al., 2022 ). Furthermore, additional factors, such as overgrazing, identified as drivers of alpine meadow degradation (Harris, 2010 ), contribute to the increasing presence of bare soil patches (Liu et al., 2003 ).…”

“…Climate and environment changes are expected to affect plant communities and consequently microbial composition ( Cregger et al, 2012 ; Mou et al, 2022 ). Shifts in plant communities, such as plant diversity, composition, and biomass, can alter litter inputs and root exudates, which in turn influence microbial diversity and its related microbial process ( Bakker et al, 2014 ; Lange et al, 2015 ; Xu et al, 2020 ; Wang G. et al, 2022 ).…”
