    Ecosystem Services of Grazed Grasslands in the Flooding Pampa

    Elizabeth J. Jacobo1,#,*, Adriana M. Rodríguez2,#

    Phyton-International Journal of Experimental Botany, Vol.93, No.6, pp. 1179-1202, 2024, DOI:10.32604/phyton.2024.050928

    Abstract The Flooding Pampa grasslands are the last remnant of the Rio de la Plata grasslands in Argentina. Anthropogenic interventions have led to severe degradation and, as a result, the ecosystem services provided by the grasslands are declining, in terms of provisioning, regulating, and supporting services. We synthesized the existing literature on the ecosystem goods and services provided by these grasslands under grazing in different conditions and conservation status. We found that plant and animal diversity and primary production are the most studied ecosystem services, while climate regulation, water supply, nutrient cycling, meat production and erosion… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.4, pp. 831-841, 2024, DOI:10.32604/phyton.2024.047560

    Abstract The responses of ecosystem nitrogen (N) and phosphorus (P) to drought are an important component of global change studies. However, previous studies were more often based on site-specific experiments, introducing a significant uncertainty to synthesis and site comparisons. We investigated the responses of vegetation and soil nutrients to drought using a network experiment of temperate grasslands in Northern China. Drought treatment (66% reduction in growing season precipitation) was imposed by erecting rainout shelters, respectively, at the driest, intermediate, and wettest sites. We found that vegetation nutrient concentrations increased but soil nutrient concentrations decreased along the… More >

    Yue Xue1, Dunqiu Fan2, Shen Su1,3,*, Jialu Fu1, Ning Hu1, Wenmao Liu2, Zhihong Tian1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.139, No.1, pp. 69-101, 2024, DOI:10.32604/cmes.2023.031488

    Abstract Decentralized finance (DeFi) is a general term for a series of financial products and services. It is based on blockchain technology and has attracted people’s attention because of its open, transparent, and intermediary free. Among them, the DeFi ecosystem based on Ethereum-based blockchains attracts the most attention. However, the current decentralized financial system built on the Ethereum architecture has been exposed to many smart contract vulnerabilities during the last few years. Herein, we believe it is time to improve the understanding of the prevailing Ethereum-based DeFi ecosystem security issues. To that end, we investigate the More >

    HSPM: A Better Model to Effectively Preventing Open-Source Projects from Dying

    Zhifang Liao1, Fangying Fu1, Yiqi Zhao1, Sui Tan2,3,*, Zhiwu Yu2,3, Yan Zhang4

    Computer Systems Science and Engineering, Vol.47, No.1, pp. 431-452, 2023, DOI:10.32604/csse.2023.038087

    Abstract With the rapid development of Open-Source (OS), more and more software projects are maintained and developed in the form of OS. These Open-Source projects depend on and influence each other, gradually forming a huge OS project network, namely an Open-Source Software ECOsystem (OSSECO). Unfortunately, not all OS projects in the open-source ecosystem can be healthy and stable in the long term, and more projects will go from active to inactive and gradually die. In a tightly connected ecosystem, the death of one project can potentially cause the collapse of the entire ecosystem network. How can… More >

    Une ontologie orientée objet pour la modélisation des socio-écosystèmes

    Éric Masson

    Revue Internationale de Géomatique, Vol.31, No.1, pp. 199-230, 2022, DOI:10.3166/RIG31.199-230

    Abstract Cet article de positionnement théorique est une contribution ontologique pour la modélisation des socio-écosystèmes (SES). C’est également une prise de position épistémique qui est ancrée sur la démarche orientée objet. Nous proposons ainsi un modèle d’organisation des connaissances qui permet d’intégrer plus de complexité dans la déconstruction pluridisciplinaire et l’analyse des SES. Cette proposition ontologique orientée objet s’appuie sur six concepts de haut niveau d’abstraction permettant une portabilité transdisciplinaire autour des structures, fonctions, connexions, phases, échelles et adaptations des SES. Après avoir défini notre positionnement sur la modélisation spatiotemporelle orientée objet, nous présentons les six More >

    ANTONIO JUÁREZ-MALDONADO*

    BIOCELL, Vol.46, No.3, pp. 651-654, 2022, DOI:10.32604/biocell.2022.017350

    Abstract The use of nanomaterials has spread and has been applied in different industries, including agriculture. Here, the possibilities presented by NMs are very varied, from the biostimulation of favorable responses, or the control of pests and diseases, to the monitoring of characteristics of interest with the use of nanosensors. Particularly the biostimulation of agricultural crops with the use of nanomaterials is very relevant, since from this process stress tolerance, higher content of biocompounds, etc., can be induced. Although the positive impacts on crops are clear, there is not enough information to determine the long-term impacts, More >
