Natural mixed forests’ carbon sequestration capacity is crucial for mitigating climate change and maintaining ecological balance. However, most of the current studies only consider role forest age, ignoring influence growth grade stand structural diversity, which leads to an increase in uncertainty large-scale sink assessment. The aim this study was quantify effects structure diversity on natural forests establish a more accurate model. Based sample data from National Forest Inventory (NFI)...
Infrared imaging is essential for detecting multiple unmanned aerial vehicle (UAV) targets detection to capture flight altitude and behavior. This study focused on a typical stealth UAV formation with flying-wing configuration. Considering the attenuation effects of clouds rain infrared spectrum, ground-based algorithm was developed. radiation conducted using apparent ray tracing method mesh clipping technology. The intensity distribution target within 8.0–12.0 μm band calculated, thermal...
Abstract BACKGROUND The ascomycete Magnaporthe oryzae is a destructive phytopathogenic fungus that causes rice blast disease and can greatly reduce yields. Due to the widespread use of synthesized chemical fungicides frequent occurrence fungicide resistance environmental pollution as result, it has become increasingly urgent develop environmentally friendly biocontrol alternatives, including plant crude extracts. RESULTS In this study, extracts tropical Millettia pachyloba were screened out...
A grating-free coupled-cavity laser (CCL) consisting of an FP semiconductor parallelly coupled with active ring resonator is demonstrated. The device exhibits a stable and accurate single-mode output (<1 GHz/mA), featuring four wavelength switchable channels spaced approximately 4 nm apart achieving side-mode suppression ratio (SMSR) up to 43.7 dB. superiority simple structure, performance, tunability, monolithic integration other optical components make this CCL promising alternative...
Abstract Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse γ -rays detectable by arrays such LHAASO. These result from proton–proton (pp) collisions very or inverse Compton (IC) scattering positron-electron pairs created pγ interactions ultra-high-energy (UHECRs). We analyzed -ray emission Coma, Perseus, and Virgo using LHAASO data. Diffuse was modeled a disk radius R 500 for each cluster while...
Abstract Site classification is the basis for evaluating forest productivity and essential tree species selection, soil fertility maintenance, management, securing carbon sinks. Despite extensive research on site evaluation, it remains unclear how to incorporate mixed variables (discrete continuous) from climate, soil, geographical, topographic factors into rank effectively. Based a large dataset 16 162 sample plots throughout Jilin Province in Northeast China, we identified environmental...
Abstract Knowledge of latitudinal patterns in plant defense and herbivory is crucial for understanding the mechanisms that govern ecosystem functioning predicting their responses to climate change. Using a widely distributed species East Asia, Quercus variabilis , we aim reveal trees with respect ontogeny along gradients. Six leaf chemical (total phenolics total condensed tannin concentrations) physical (cellulose, hemicellulose, lignin dry mass concentration) defensive traits as well (%...
Abstract The upcoming climatic variability is expected to influence the population dynamics of tree species, but few empirical studies have been performed over broad geographical scales, which may be more convincing address range shift under climate change. In present study, structure and regeneration Quercus variabilis were investigated along latitudinal longitudinal gradients its full in China. size structure, density, mortality rate ( b ), conversion CR initial recruitment y 0 survival...
Abstract Forests play a key role in regulating the global carbon cycle, substantial portion of which is stored aboveground biomass (AGB). It well understood that biodiversity can increase through complementarity and mass‐ratio effects, contribution environmental factors stand structure attributes to AGB was also observed. However, relative influence these determining Quercus forests remains poorly understood. Using large dataset retrieved from 523 permanent forest inventory plots across...
Societal Impact Statement Combining natural and social science approaches to conduct archeological research on wooden cultural relics is important for exploring major aspects of ancient civilizations. The Forbidden City in Beijing, China, the largest existing palace complex world. We examined DNA imperial wood “Nanmu” specimens taken from representative structural components City, order provide a new perspective long‐standing dispute about its species. This allowed us accurately identify...
To reduce the risk of resistance development, a novel fungicide with dual specificity is demanded. Trehalose absent in animals, and its synthases, trehalose-6-phosphate synthase (TPS) phosphatase (TPP), are safe targets. Here, we report discovery dual-specificity inhibitor MoTps1 (Magnaporthe oryzae Tps1, TPS) MoTps2 (M. Tps2, TPP). The inhibitor, named A1-4, was obtained from virtual screening subsequent surface plasmon resonance screening. In vitro assays, A1-4 interacts MoTps2-TPP (MoTps2...
We studied the heterogeneity of soil weed seed-bank in a rice-wheat rotation system after long-term application different organic or non-organic fertilizers, and effects major nutrients on characteristics seed-bank. The was sampled Taihu area 31-year fertilization experiment. Weed seeds were identified counted surface 12 differentially treated areas using microscopic examination, analyzed by Simpson, Shannon, Margalef, Pielou indexes. fertilizers could significantly reduce density seed-bank;...
<title>Abstract</title> The structural properties of mixed stands and their effects on forest carbon sink function have attracted the attention managers. Understanding comprehensive stand factors structure biomass is critical for better management. However, data information variability its relationships to features are still insufficient. purpose this study was develop models linking stand-level with structure, quantify each variable in natural forests, especially structure. Four machine...
Species-unique genes that encode specific proteins and have no homologs in other species play certain roles the evolution of adaptations to external environments. Nevertheless, biological unique plant pathogenic fungi remain largely unknown. Here, four Magnaporthe-unique (MUG1–MUG4), which were highly expressed during early infection stages, functionally characterized rice blast fungus Magnaporthe oryzae. Subcellular localization assays revealed Mug1, Mug2, Mug4 localized cytoplasm Mug3 was...
