Experimental warming alters the community composition, diversity, and N2 fixation activity of peat moss (Sphagnum fallax) microbiomes

AA Carrell, M Kolton, JB Glass… - Global Change …, 2019 - Wiley Online Library
Sphagnum‐dominated peatlands comprise a globally important pool of soil carbon (C) and
are vulnerable to climate change. While peat mosses of the genus Sphagnum are known to …

Ecoenzymatic stoichiometry and microbial processing of organic matter in northern bogs and fens reveals a common P-limitation between peatland types

BH Hill, CM Elonen, TM Jicha, RK Kolka, LRLP Lehto… - Biogeochemistry, 2014 - Springer

Whole-ecosystem warming increases plant-available nitrogen and phosphorus in an ombrotrophic bog

CM Iversen, J Latimer, DJ Brice, J Childs… - Ecosystems, 2023 - Springer
Warming is expected to increase the net release of carbon from peatland soils, contributing
to future warming. This positive feedback may be moderated by the response of peatland …
