otal forest carbon storage of Langxi Forest Farm was 205×104 t, and the carbon density ranged from 8.56 to 145.74 t·hm-2, with a mean value of 57.98 t·hm-2. Overall, the distribution pattern of carbon storage was high in the northwest and low in the southeast, while high in the edge and low in the interior. By improving the parameter heterogeneity and residual spatial autocorrelation in the GWR model, we can accurately assess the spatial relationship between forest carbon storage and relevant variables in the study area, and improve the estimation accuracy of the forest carbon storage and its spatial distribution at the regional scale.We measured the annual net biomass growth, carbon content of each component and soil heterotrophic respiration in four low-efficiency interplanting patterns, i.e., Pinus massoniana stands interplanting Myrica rubra, Sapindus mukurossi, Camellia oleifera and Gardenia jasminoides in Changting County, Fujian Province, with the aim to analyze the effects of interplanting patterns on carbon storage pattern and carbon balance of low-efficiency P. massoniana stand. The ranges of carbon content in different organs of M. rubra, S. mukurossi, C. oleifera, G. jasminoides and P. massoniana were 41.1%-50.1%, 42.2%-50.6%, 45.1%-48.9%, 44.7%-49.6% and 46.1%-51.9%, respectively. Carbon content of the same organ significantly differed among tree species. The pattern of P. massoniana interplanting M. rubra and S. mukurossi had the highest carbon stock and annual net carbon increase reserves, with values of 67.62-68.42 t·hm-2 and 9.21-9.45 t·hm-2·a-1, respectively. Followed by the lower pattern of C. oleifera, G. jasminoides, wi could improve the carbon income of the low-efficiency P. massoniana stand ecosystem.To understand the nutrient use strategies of 11 tree species in a subtropical common-garden, we measured the specific leaf area, nitrogen (N) and phosphorus (P) resorption and stoichiometric characteristics of leaves in August 2019. The results showed that the specific leaf area, N and P concentrations in mature and senescent leaves of evergreen broadleaved (Lindera communis, Cinnamomum camphora, Schima superba, Castanopsis carlesii, Michelia macclurei and Elaeocarpus decipiens) and coniferous species (Cunninghamia lanceolata and Pinus massoniana) were lower than those of deciduous broadleaved species (Liquidambar formosana, Sapindus mukorossi and Liriodendron chinense). In contrast, CN and CP in mature leaves of evergreen broadleaved and coniferous species were significantly higher than those of deciduous broadleaved species. https://www.selleckchem.com/products/dyngo-4a.html Except for C. carlesii, the NP of all the species were lower than 14. Compared with other tree species, N and P resorption efficiencies of S. mukorossi were higher than 50% based on bots here, did not exhibit higher P resorption efficiency. Our results provided scientific support for afforestation practice in the mid-subtropics.Terrestrial ecosystems are the core components of the biosphere, supporting human life, production and social and economic activities. With the development of human civilization and the progress of science and technology, the continued expanding resources utilization in terms of scale and intensity has caused environmental problems, including global climate change, biodiversity loss, environmental pollution, resource depletion and ecosystem degradation, which threaten the sustainable development of our society. The public expects ecological research providing scientific theories and systematic solutions for the utilization and protection of ecosystems at the continental and global scale, and the maintenance of sustainable development of human society as well. This study aimed to serve the ecological civilization construction in China, ecological security pattern construction, regional ecological and environmental governance, and the development of macrosystem ecology. We reviewed the effectiveness and experience of regional ecological and environmental governance in China, analyzed the scientific requirements and the characteristics of the times of China's eco-civilization construction towards large-scale ecological research, and proposed using a new philosophy, i.e., nature-based macroecosystem approach, to improve the ecological and environmental governance and ecological security pattern construction at the regional scale. Based on the above-mentioned expounding, we discussed the strategic plan, technical approaches and technological support system of large-scale ecological security pattern construction and ecological and environmental governance in China. This review could provide theoretical references for safe, healthy and beautiful land spatial construction and the progress of eco-civilization of China.Nurses have a crucial role in infection prevention and control. The coronavirus disease 2019 (COVID-19) pandemic has emphasised the importance of controlling the spread of infections, while reinforcing the challenges involved in the care of patients who already have an infection. This article discusses important elements of theory and practice related to infection prevention and control. The author also explores various areas that have come to prominence as a result of the COVID-19 pandemic, including measures such as risk assessment, the use of personal protective equipment, the role of surveillance, and outbreak management. Corneal diseases is a major cause of reversible blindness in the world. Monitoring the progression of human corneal edema or corneal scarring to prevent the disease entering into the end stage is crucial. We present a method for sensing human corneal composition at different depths, namely focused on the epithelium and stromal layer, using high-sensitivity terahertz (THz) broadband spectroscopy. From the proposed methodology, the THz temporal and absorption spectra of human corneas at different edema stages have been studied. THz wave signals were collected from the direct reflection and four other collection points along the THz wave propagation direction as reviewed from the simulation THz electrical field. Our results show that the epithelium layer acts as a good barrier to maintain hydration level of the stroma, and the quality of the epithelium can be used to predict the level of corneal swelling in corneal edema. At the detection points near to the incident point, the THz frequency spectra demonstrated interference oscillation behavior.
