2024-10-31A revised taxonomic system of the genus Saussurea (Asteraceae)Saussurea is one of the largest and most rapidly evolving genera within the Asteraceae, comprising approximately 520 species from the Northern Hemisphere. Saussurea is one of the largest and most rapidly evolving genera within the Asteraceae, comprising approximately 520 species from the Northern Hemisphere. These species exhibit extraordinary diversity in both morphologies and preferred habitats. A comprehensive infrageneric classification, supported by robust phylogenetic trees and corroborated ...Read More -

Salvia is the largest genus of Lamiaceae, characterized by lever-like modified stamens, comprising approximately 1,000 species worldwide, with extensive radiation in Central and South America, Western Asia and Eastern Asia. High species diversity of Salvia has been recorded in China, and most of these species are endemic species. Early taxonomic...Read More -
2024-10-29Diazotrophs fix nitrogen in nitrogen-rich forest soils as driven by carbon inputsEntitled‘Soil diazotrophs sustain nitrogen fixation under high nitrogen enrichment via adjustment of community composition’and‘Plant and Microbial Carbon Are Important Drivers of Free-Living Nitrogen Fixation in Tropical Forest Soils:A New Discovery of Carbon-Driven Nitrogen Input’. Free-living nitrogen fixation (FLNF) serves as an important nitrogen (N) source in terrestrial ecosystems. Numerous previous studies have indicated that N addition inhibits the rate of FLNF, which contradicts with increasing recent research. The mechanisms driving FLNF in N-rich environments remain unclear. FLNF is a typical energy-consuming pro...Read More -
2024-10-27Differential responses and mechanistic controls of soil phosphorus transformation in Eucalyptus plantations with N fertilization and introduced N2-fixing tree speciesA conceptual framework of how N fertilizationand D.odoriferahelp Eucalyptus for increasing demand for phosphorus through microbial PLFA and ACP activity. Eucalyptus is one of the most extensively planted commercial plantation timber genera in tropics and subtropics. Introducing N2-fixing tree species into Eucalyptus plantations has been widely considered as one of optimal silvicultural practices to balance N losses due to timber harvesting and reduce the demand for N fertilizer. However, N enrich...Read More -
2024-10-27Plant resource inputs can lead to rapid alterations of forest soil DOM compositionfound that plant resource inputs can lead to rapid alterations of forest soil dissolved organic mattercomposition. In a new study, Dr. LU Xiankai and his colleagues, from South China Botanical Garden (SCBG) of the Chinese Academy of Sciences (CAS), found that plant resource inputs can lead to rapid alterations of forest soil dissolved organic matter (DOM) composition.DOM plays a key role in forest carbon biogeochemistry by linking soil organic carbon (SOC) s...Read More -
2024-10-21Precipitation, solar radiation, and their interaction modify leaf hydraulic efficiency-safety trade-off across angiospermsIdentifying trade-offs is necessary for understanding trait variation and ecological strategies across species and habitats. In theory, there is a trade-off between hydraulic efficiency and safety. However, the strength and direction of this trade-off at the leaf level are not consistent across studies, and habitat climate may impact this trade-...Read More -
2024-10-21Researchers Investigate Organic Carbon Sources in Mangrove SedimentsMangrove forests are one of the most productive blue carbon ecosystems (BCEs), offering a range of ecosystem services including fisheries production, coastal protection, sediment fixation, and notably, carbon sequestration. Mangrove sediments hold approximately 70% of the whole ecosystem carbon (C) storage, varying in magnitude geographically, w...Read More
