Recent advances in domain adaptation show that deep self-training presents a powerful means for unsupervised adaptation. These methods often involve an iterative process of predicting on target and then taking the confident predictions as pseudo-labels retraining. However, since can be noisy, put overconfident label belief wrong classes, leading to deviated solutions with propagated errors. To address problem, we propose confidence regularized (CRST) framework, formulated self-training. Our...
Abstract Soil net nitrogen mineralization rate (N min ), which is critical for soil availability and plant growth, thought to be primarily controlled by climate physical and/or chemical properties. However, the role of microbes on regulating N has not been evaluated global scale. By compiling 1565 observational data points potential from 198 published studies across terrestrial ecosystems, we found that significantly increased with microbial biomass, total nitrogen, mean annual...
Soil nitrification, an important pathway of nitrogen transformation in ecosystems, produces soil nitrate that influences net primary productivity, while the by-product nitrous oxide, is a significant greenhouse gas. Although there have been many studies addressing microbiology, physiology, and impacting environment factors nitrification at local scales, are very few on rate over large scales. We conducted global synthesis patterns controlling normalized 25°C by compiling 3,140 observations...
The denitrification process profoundly affects soil nitrogen (N) availability and generates its byproduct, nitrous oxide, as a potent greenhouse gas. There are large uncertainties in predicting global because controlling factors remain elusive. In this study, we compiled 4301 observations of rates across variety terrestrial ecosystems from 214 papers published the literature. averaged rate was 3516.3 ± 91.1 µg N kg-1 day-1 . highest 4242.3 152.3 under humid subtropical climates, lowest 965.8...
Abstract Growing evidence indicates that plant community structure and traits have changed under climate warming, especially in cold or high-elevation regions. However, the impact of these warming-induced changes on ecosystem carbon sequestration remains unclear. Using a warming experiment Qinghai-Tibetan Plateau, we found not only increased species height but also altered composition, collectively resulting taller associated with net productivity (NEP). Along 1,500 km transect promoted NEP...
The Atg4 cysteine proteases are required for processing Atg8 the latter to be conjugated phosphatidylethanolamine on autophagosomal membranes, a key step in autophagosome biogenesis. Notably, whereas there only one atg4 and atg8 gene yeast, mammals have four homologues six homologues. seem play different roles biogenesis, previous studies had indicated that they could differentially processed by present study provided first detailed kinetics analysis of all against representative data Atg4B...
Abstract Terrestrial ecosystems currently function as a net carbon (C) sink for atmospheric C dioxide ( CO 2 ), but whether this can persist with global climate change is still uncertain. Such uncertainty largely comes from turnover time in an ecosystem, which critical parameter modelling cycle and evaluating potential. Our current understanding of how long be stored soils vegetation what controls spatial variations on large scale very limited. We used data stocks influx 2,753 plots 1,087...
Abstract Nitrogen immobilization usually leads to nitrogen retention in soil and, thus, influences supply for plant growth. Understanding is important predicting cycling under anthropogenic activities and climate changes. However, the global patterns drivers of remain unclear. We synthesized 1350 observations gross rate (NIR) from 97 articles identify NIR. The mean NIR was 8.77 ± 1.01 mg N kg −1 day . It 5.55 0.41 croplands, 15.74 3.02 wetlands, 15.26 2.98 forests. increased with annual...
Abstract Disentangling the relative response sensitivity of soil autotrophic ( R a ) and heterotrophic respiration h to nitrogen (N) enrichment is pivotal for evaluating carbon (C) storage stability in scenario intensified N deposition. However, mechanisms underlying differential sensitivities contribution s with increasing deposition remain elusive. A manipulative field experiment multi‐level addition rates was conducted over 3 years (2015–2017) an alpine meadow explore impact on / ratio...
Abstract Globally, soils store two to three times as much carbon currently resides in the atmosphere, and it is critical understand how soil greenhouse gas (GHG) emissions uptake will respond ongoing climate change. In particular, soil‐to‐atmosphere CO 2 flux, commonly though imprecisely termed respiration ( R S ), one of largest fluxes Earth system. An increasing number high‐frequency measurements (typically, from an automated system with hourly sampling) have been made over last decades;...
Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) shows great potential for forest height retrieval. However, there are abundant noise photons in the ICESat-2 data, which make accurate extraction of global heights challenging. In this letter, a novel algorithm based on clustering method ordering points to identify structure (OPTICS) was proposed remove photons. First, we modified circular shape search area OPTICS an elliptical shape. Second, distance all generated using algorithm....
FengYun-3E (FY3E), launched on 5 July 2021, is one of China’s polar-orbiting meteorological satellite series. The GNOS II onboard FY3E an operational GNSS remote sensor that for the first time combines radio occultation (GNSS RO) and reflectometry (GNSS-R). It has eight reflection channels can track specular points at same time, receiving reflected signals from multiple systems, including GPS, BeiDou Galileo. basic GNSS-R output generated by a 122 × 20 non-uniform delay-Doppler map whose...
Abstract Peatland ecosystems are globally important carbon stores. Disturbances, such as drainage and climate drying, act to lower peatland water table depths, consequently enhancing soil release subsidence rates. Here, we conduct a global meta-analysis quantify the relationship among depth, subsidence. We find that decline stimulated heterotrophic, rather than autotrophic, respiration, which was associated with an increase in rate. This held across different zones land uses. 81% of total...
Abstract The relationship between biodiversity and ecosystem functioning has mainly focused on plant communities, with comparably little known about soil microbial‐driven functions. Climate change severely threatens microbial roles, but how communities determine multifunctionality under climate is poorly understood. Here, we evaluated the effects of diverse bacterial fungal properties, including gene abundance, diversity network complexity, (nine functions) across a 3000 km transect along...
