Changes in biocrust cover drive carbon cycle responses to climate change in drylands
Open accessAbstract
Dryland ecosystems account for ca. 27% of global soil organic carbon (C) reserves, yet it is largely unknown how climate change will impact C cycling and storage in these areas. In drylands, soil C concentrates at the surface, making it particularly sensitive to the activity of organisms inhabiting the soil uppermost levels, such as communities dominated by lichens, mosses, bacteria and fungi (biocrusts). We conducted a full factorial warming and rainfall exclusion experiment at two semiarid sites in Spain to show how an average increase of air temperature of 2–3 °C promoted a drastic reduction in biocrust cover (ca. 44% in 4 years). Warming significantly increased soil CO 2 efflux, and reduced soil net CO 2 uptake, in biocrust‐dominated microsites. Losses of biocrust cover with warming through time were paralleled by increases in recalcitrant C sources, such as aromatic compounds, and in the abundance of fungi relative to bacteria. The dramatic reduction in biocrust cover with warming will lessen the capacity of drylands to sequester atmospheric CO 2. This decrease may act synergistically with other warming‐induced effects, such as the increase in soil CO 2 efflux and the changes in microbial communities to alter C cycling in drylands, and to reduce soil C stocks in the mid to long term.

“Because of the low CO2 efflux rates typically observed in areas such as those studied here (Castillo-Monroy et al., 2011; Rey et al., 2011), each measurement period was 120 s to ensure reliable measurements.”

“While the importance of biodiversity for C cycling and storage in terrestrial ecosystems is well-known (Cardinale et al., 2012; Maestre et al., 2012b; Strassburg et al., 2010), it is less certain how possible alterations in biotic communities induced by climate change will directly impact these processes (but see Zhou…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
