2025-04-23From Rhizosphere to Resorption: Comparing Phosphorus Adaptation in Trees and Herbs Under Decadal Acid Rain StressA 12-year acid rain simulation study shows tropical trees maintain stable phosphorus (P) despite declining soil inorganic P, while herbs decline leaf P and fresh litter P due to reduced soil inorganic and organic soil P. Tree rhizosphere P fraction is linked to soil physicochemical properties, whereas herbs rely on microbial-driven organic P min... As global soil acidification intensifies, tropical and subtropical forests face growing phosphorus (P) limitations, raising questions about which functional group—trees or herbs—would be disproportionately affected. To address this, researchers from the South China Botanical Garden, Chinese Academy of Sciences, conducted a long-term acid rain ...Read More -

2025-04-17200,000-Year Dune Chronosequence Reveals Synergistic Regulation of Climate and Pedogenesis on Soil Organic Matter TransformationSelected two coastal dune chronosequences spanning 2 million years—Jurien Bay in a hot, arid climate and Warren in a wet, cold climate (Figure 1)—to systematically analyze the influence of climate and pedog Against the backdrop of intensifying global climate change, a deeper understanding of soil carbon sequestration mechanisms is crucial for enhancing the carbon sink function and stability of terrestrial ecosystems. Dissolved organic matter (DOM) and glomalin-related soil protein (GRSP), as key components of the soil carbon pool, play pivotal role...Read More -

2025-04-10Successful reintroduction of Primulina speciesRecoprocal transplant experiments were conducted to explore the adaptability of Primulina species to different karst cave habitats and confirm whether there are alternative habitats for conservation translocation. The results showed that P. huaijiensis, P. rubella and P. fengkaiensis could adapt to twilight zone of alternative caves under simila... Karst caves are hotspots of biodiversity and endemism, but threatened by human unsustainable activities. Many cave plants are site-endemic restricted in isolated caves and are at risk of extinction due to habitat loss. Therefore, it is urgent to protect these endemic cave plants in situ and find other alternative habitats for conservation transl...Read More
