2024-11-21Contrasting responses of soil organic carbon dynamics to different nitrogen−addition approachesChronic atmospheric nitrogen (N) deposition caused by anthropogenic activities has dramatically affected terrestrial ecosystem carbon (C) cycling, especially in tropical and subtropical forests. Many studies based on experimental platform of understory N addition (UN) have proved that long-term N addition significantly stimulated the accumulatio...Read More -

2024-11-16The evolutionary history of “living fossils”: Lineage differentiation and genomic vulnerability of Bretschneidera sinensisMany relict species were widespread during the last glacial period, but now are often characterized by narrow geographic distribution, small population sizes, and limited dispersal capacity. The subtropical forests of East Asia, distinguished by their high plant diversity and endemism, are home to abundant ancient relict species. These relict species are commonly known as “living fossils” because their morphological characteristics have remained virtually unchanged over long periods of time.Many relict species were widespread duri...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
