Moisture Controls on Trace Gas Fluxes in Semiarid Riparian Soils

Variability in seasonal soil moisture (SM) and temperature (T) can alter ecosystem/atmosphere exchange of the trace gases carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). This study reports the impact of year-round SM status on trace gas fluxes in three semiarid vegetation zones, mesquite (30 g organic C kg soil), open/ forb (6 g organic C kg soil), and sacaton (18 g organic C kg s...

Wild-boar disturbance increases nutrient and C stores of geophytes in subalpine grasslands.

UNLABELLED PREMISE OF THE STUDY Wild-boar soil disturbance (i.e., rooting) increases the abundance of some species of geophytes (i.e., plants with underground renewal buds) in upland meadows. However, the mechanisms that could lead to such enhanced prevalence remain unexplored. • METHODS We analyzed the effects of wild-boar disturbance on the size, nutrient (N, P, K, C, and total ash), and...

Contrasting microbial biogeographical patterns between anthropogenic subalpine grasslands and natural alpine grasslands.

The effect of plant species composition on soil microbial communities was studied at the multiregional level. We compared the soil microbial communities of alpine natural grasslands dominated by Carex curvula and anthropogenic subalpine pastures dominated by Nardus stricta. We conducted paired sampling across the Carpathians and the Alps and used Illumina sequencing to reveal the molecular dive...
