Ecosystem gross primary productivity (GPP) is the largest carbon flux between atmosphere and biosphere strongly influenced by soil moisture. However, response acclimation of GPP to moisture remain poorly understood, leading large uncertainties in characterizing impact on Earth system models. Here we analyze GPP-soil curves at 143 sites from global FLUXNET. We find that 108 exhibits hump-shaped with increasing moisture, an apparent optimum ( $${{\rm{SM}}}^{{\rm{GPP}}}_{{\rm{opt}}}$$ , which...
<title>Abstract</title> <italic>Background </italic>The Tibetan Plateau (TP), a vast alpine region with substantial soil organic carbon (SOC) stocks, plays crucial role in the regional cycle and climate change mitigation. However, our understanding of spatial distribution underlying drivers SOC across TP remains limited. <italic>Methods</italic> We quantified horizontal (1 km resolution) vertical (0–200 cm depth) patterns density (SOCD) using 1,561 samples fully trained validated Random...
Abstract Global hydroclimatic variability is increasing with more frequent extreme dry and wet years, severely destabilizing terrestrial ecosystem productivity. However, what regulates the consequence of precipitation extremes on productivity remains unclear. Based a 9‐year field manipulation experiment Qinghai–Tibetan Plateau, we found that responses gross primary (GPP) to drought wetness were differentially regulated by nitrogen (N) deposition. Over N deposition, events reduced GPP more....
Drought has broad and deep influences on ecosystem dynamics functions, particularly considering the lagged cumulative effects of drought. Yet individual role climate variables in mediating such drought vegetation remains largely unknown. Based Normalized Difference Vegetation Index (NDVI) standard precipitation evapotranspiration index (SPEI), here, we investigated patterns mechanisms alpine grasslands Qinghai–Tibetan Plateau (QTP) from 1982 to 2015. imposed widespread impacts with notable...
Plant traits reflect the response and adaptation of plants to environmental changes play important roles in prediction effects different conditions on plant-mediated processes. However, few studies have focused nonvascular plants, such as bryophytes, although are participants primary productivity biogeochemistry harsh environments. In this study, adaptive morphological their interactions moss species that adapt acute changeable environment were determined. Environmental factors drive these...
The alpine grassland on the Qinghai–Tibet Plateau (AGQTP) has undergone severe climate change. Although carbon budget of AGQTP proved to have altered significantly, spatiotemporal dynamics and driving mechanism changes remain debated. This study estimated gross primary productivity (GPP), ecosystem respiration (ER), net (NEP) AGQTP, based remote sensing models, analyzed their climatic mechanism. Our results showed that GPP, ER, NEP increased at rates 0.002 Pg C yr−2, 0.013 0.0007...
Abstract Droughts typically exert negative effects on vegetation growth, which largely depend the timing of drought onset. However, huge inconsistencies exist in seasonal response to among diverse regions across globe. Here, using leaf area index (LAI) and solar‐induced chlorophyll fluorescence (SIF), we quantified susceptibility by calculating coincidence rate between suppression extremes soil droughts, further investigated spatiotemporal changes during different seasons from 2001 2021. We...
