27 de may. de 2024 · We show that whole-soil warming has a much stronger effect on soil carbon emission in the alpine grassland ecosystem than what was reported in previous warming experiments, most of which only...
9 de mar. de 2017 · The response of whole-soil profiles to warming has not been tested in situ. In a deep warming experiment in mineral soil, we found that CO 2 production from all soil depths increased with 4°C warming; annual soil respiration increased by 34 to 37%.
21 de may. de 2021 · Subsoils below 20 cm are an important reservoir in the global carbon cycle, but little is known about their vulnerability under climate change. We measured a statistically significant loss of subsoil carbon (−33 ± 11%) in warmed plots of a conifer forest after 4.5 years of whole-soil warming (4°C).
We found that the microbial CUE decreased with soil depth in an alpine grassland, and was mainly controlled by soil C availability. However, short-term (3.3 y) whole-soil-profile warming (0 to 1 m, +4 °C) did not significantly affect either soil available C or microbial CUE across soil depths.
1 de mar. de 2023 · Based on a whole-soil-profile warming (3–4 °C across 0−100 cm) experimental platform in an alpine meadow on the Qinghai-Tibetan Plateau, we investigated the responses of plant species diversity, community composition, biomass, and NPP to warming from 2018 to 2021.
30 de mar. de 2023 · Here we show that 4.5 years of whole-soil warming (+4 °C) resulted in less polymeric SOC (sum of specific polymers contributing to SOC) in the warmed subsoil (20–90 cm) relative to control,...
30 de mar. de 2023 · A field-based study of 4.5 years of whole-soil warming reveals that warming stimulates loss of structurally complex organic carbon at the same rate as that for bulk organic carbon in subsoil.
