Avian influenza virus continues to pose zoonotic, epizootic, and pandemic threats worldwide, as exemplified by the 2020-23 epizootics of re-emerging H5 genotype avian influenza viruses among birds and mammals and the fatal jump to humans of emerging A(H3N8) in early 2023. Future influenza pandemic threats are driven by extensive mutations and reass...

Summary. The East Palaearctic group of species in the subgenus Hypericia Bedel, 1899 (genus Chrysolina Motschulsky, 1860) is reviewed. Chrysolina (H.) nikkoensis (Jacoby, 1885) is first recorded for Kurile Islands and the Russian fauna, its type specimens studied and redescription is provided. Chrysolina (Hypericia) changbaishana sp. n. is describe...

Higher education institutions actively pursue transnational strategic alliances at the organizational level, but what are the rationales, pathways and benefits behind this pursuit? A systematic literature review in the Web of Science and Scopus reveals the majority of studies touching on this topic are descriptive, lacking definitions and theoretic...
Purpose Although the formation mechanism of the megadunes in the Badain Jaran Sand Sea has received considerable research attention, their provenance and sand accumulation processes are still poorly understood. Therefore, this study aims to identify the provenance of the megadunes and clarify the spatial and temporal characteristics of their source...
Ecosystems provide a wide range of services crucial for human well-being and decision-making processes at various levels. This study analyzed the major land cover types of north-central Ethiopia and their impact on total and per-capita ecosystem service value (ESV). The ESV was estimated using the benefit-transfer method along the established globa...
This paper analyses published research in port economics, policy and management (port studies) based on examining all relevant academic journal papers published from 2009 to 2020. The systematic review of all 1227 papers relies on quantitative and qualitative bibliometric tools to reveal the structures of the research community (i.e., authors' coun...

凋落物分解是陆地和水域生态系统碳循环的关键过程。凋落物分解模型通常认为控制凋落物分解速率最重要的驱动因素依次为环境条件、凋落物性状和分解者组成。然而这一凋落物分解层级模型的适用性是否在入侵植物和土著植物间具有差异尚不清楚。本研究通过比较中国滨海盐沼中广泛分布的入侵植物互花米草和土著植物芦苇, 探究控制植物凋落物分解的驱动因子层级关系是否因物种而异。本研究跨18°纬度采集了两种植物的叶片凋落物以获得较大变异的凋落物性状, 通过选择三个不同纬度的分解地(东营、上海、漳州)以控制分解环境, 同时选择三种不同孔径(0.1、2和5 mm)的凋落物袋以控制分解者类群。经过90天的野外分解实验, 结果表明:(1)互花米草叶片凋落物分解速率是芦苇叶片凋落物的2.2倍; (2)无论分解地和凋落物袋网目大小, ...
