Clockwise or Counterclockwise: Hysteresis in the Response of Ecosystem Respiration to TemperatureNARA Subscribed
Ecosystem respiration (ER) often responds asymmetrically to seasonal warming and cooling, producing thermal hysteresis. Yet, its global patterns and drivers remain unknown. Here, we used daily ER data from 324 eddy‐covariance sites worldwide and revealed two contrasting hysteresis patterns in the temperature response of ER: clockwise hysteresis (ER is higher during the warming than cooling season) at 173 sites and counterclock...
Synergistic Interactions Between Warming and Elevated Atmospheric CO 2 Increase Soil Organic Carbon SequestrationNARA Subscribed
Warming and elevated CO 2 (eCO 2 ) are two potentially opposing climate‐carbon (C) feedback mechanisms that modulate the magnitude of the land C sink, with warming decreasing and eCO 2 increasing C sequestration. However, their net effect on soil organic C (SOC)—the largest terrestrial C stock—remains uncertain. Here, we quantify how warming, eCO 2 , and their interactions influence SOC by using 5558 paired observations from 1...
Precision measurement of the Ds*+-Ds+ meson mass differenceNARA Subscribed
Coastal wetlands are critical blue carbon reservoirs, yet the depth‐resolved impacts of warming on belowground carbon dynamics remain poorly understood. Over the course of an 8‐year in situ experiment, we investigated plant‐derived carbon inputs, soil carbon losses via respiration, and microbially mediated carbon fixation across a 60 cm soil profile under a projected 2°C atmospheric warming scenario. Plant carbon fixation (abo...
As a promising strategy for improving soil health and mitigating climate change, biochar has received increasing attention in recent years. However, findings regarding its microbial effects are often context-dependent, and the complex impacts of biochar on soil microbial communities remain inadequately understood. Here, we integrated 843 samples of 16 S rRNA sequencing data from 24 independent studies, utilizing machine learni...
Congo Basin Carbon Cycle Responses to Global ChangeNARA Subscribed
The Congo Basin and its contiguous forests harbor globally significant carbon stocks, estimated at 65 gigatons of C (GtC) above and belowground. Despite rising temperatures and intensifying droughts, they have remained a carbon sink, albeit weak: 0.26–0.50 GtC yr. −1 carbon uptake since 1980. However, these forests' carbon stocks and fluxes, including gross primary productivity, respiration, net primary productivity, and river...
Accelerated Speciation in Temperate Cannabaceae: The Role of Pre‐Adaptation, Ecological Opportunities and Niche DivergenceNARA Subscribed
Aim The macroevolutionary processes underlying biome transitions and the geographical distribution of species diversity and ecological traits remain poorly understood in most clades. Here, we study tropical‐to‐temperate transitions in Cannabaceae (the hemp family) and hypothesize that pre‐adaptation (i.e., deciduous leaves) and ecological opportunities in temperate habitats have led to niche divergence and increased speciation...
