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 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...

The number of wheat ears is an essential indicator for production and yield estimation, but accurately obtaining requires expensive manual cost labor time. Meanwhile, the characteristics provide less information, color consistent with background, which can be challenging to obtain required. In this paper, performance Faster regions convolutional neural networks (Faster R-CNN) RetinaNet predict at different growth stages under conditions investigated. results show that using Global WHEAT...

Abstract Crop growth monitoring and yield estimate information can be obtained via appropriate metrics such as the leaf area index (LAI) biomass. Such is crucial for guiding agricultural production, ensuring food security, maintaining sustainable development. Traditional methods of field measurement typically have low efficiency only give limited untimely information. Alternatively, based on remote sensing technologies are fast, objective, nondestructive. Indeed, data assimilation crop...

The normalized difference vegetation index (NDVI) is crucial to many sustainable agricultural practices such as monitoring and health evaluation. However, optical remote sensing data often suffer from a large amount of missing information due sensor failures harsh atmospheric conditions. synthetic aperture radar (SAR) offers new approach filling in based on its excessive revisit density potential image without interference clouds rain. Due the imaging mechanisms between SAR sensors, it very...

Release of substance P (SP) from nociceptive nerve fibers and activation its receptor neurokinin 1 (NK1) are important effectors in the transmission pain signals. Nonetheless, role SP muscle remains unknown. Here we show that a single i.m. acid injection mice lacking signaling by deletion tachykinin precursor ( Tac1 ) gene or coadministration NK1 antagonists produces long-lasting hyperalgesia rather than transient seen control animals. The inhibitory effect was found exclusively neurons...

Abstract Warming can affect soil microbial respiration by changing biomass and community composition. The responses of to warming under experimental conditions are also related background the setup, such as magnitude, duration, methods. However, global pattern in response underlying mechanisms remain unclear. Here, we conducted a meta-analysis synthesizing data from 187 field experiments. We found that significantly increased carbon 11.8% 6.4%, respectively. warming-induced increase...

Abstract Soil nitrogen (N) mineralization is crucial for the sustainability of available soil N and hence ecosystem productivity functioning. Metabolic quotient ( Q min ), which defined as net per unit microbial biomass N, reflects efficiency mineralization. However, it far from clear how changes what are controlling factors at global scale. We compiled 871 observations 79 published articles across terrestrial ecosystems (croplands, forests, grasslands, wetlands) to elucidate variation its...

Abstract Background Nitrogen (N) and phosphorus (P) deposition have largely affected soil respiration ( R s ) in forest ecosystems. However, few studies explored how N P individually or combination to influence its components (autotrophic respiration, a ; heterotrophic h ), especially highly P-limited subtropical forests. To address this question, we conducted field manipulation experiment with and/or addition 50-year-old secondary forest. Results We found that on average reduced , by 15.2%,...
