2024-12-01Niche Shifts Facilitate Mycorrhizal Fungal Specialization in BurmanniaMany questions on the relationships between mycoheterotrophic plants and their mycorrhizal fungal partners remain unknown, particularly the environmental factors underpinning the fungal specialization in mycoheterotrophs. This study assessed fungal communities in mycoheterotrophic plants and their co-occurring plants to reveal the ecological fac... Mycoheterotrophic plants (MHPs) are achlorophyllous and obtain nutrients through parasitizing mycorrhizal fungi. MHPs evolved from autotrophic ancestors independently but show obvious convergent evolution in adaptation to their life mode, such as reduced vegetative growth and habitat changes from open grassland/shrub-land to dense moist forests,...Read More -
2024-12-01Check dam promotes soil organic carbon accumulation and nitrogen and phosphorus depositionThis study explored the effects of check dams on carbon (C), nitrogen (N), and phosphorus (P) content, stoichiometry, and their depth-dependence in mangrove wetlands. The results show that check dams significantly enhanced C, N, and P accumulation, increased soil C:P and N:P stoichiometry, and altered the depth-dependence of C dynamics, with soi... Mangroves are vital coastal ecosystems that provide essential ecological services, including carbon (C) sequestration and the removal of nitrogen (N) and phosphorus (P) pollution. With the expansion of agricultural activities and aquaculture, an increasing number of check dams have been constructed around mangrove wetlands, resulting in changes ...Read More -
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 -
