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 -
2025-04-02New Species of Gesneriaceae Discovered in Guangdong Karst——Primulina nanlingensisA new species of Gesneraceae, Primalina nanlingensis, was discovered in the karst region of northern Guangdong's Nanling Mountain Range, enriching the area's plant diversity. Through morphological comparisons and molecular phylogenetic analysis, researchers confirmed its distinctiveness from related species and proposed habitat conservation meas... A research team from the South China Botanical Garden, Chinese Academy of Sciences, has discovered and named a new species of Gesneraceae plant, Primulina nanlingensis, in the limestone karst region of northern Guangdong. This discovery adds a rare member to the plant diversity treasure trove of the Nanling Mountain Range.The genus Primulina is ...Read More -
2025-03-23Plant nitrogen uptake preference and drivers in natural ecosystems at the global scalePlant nitrogen (N) uptake for different soil N forms is one of the most critical N strategie to mitigate N competition among plants, maintain plant growth, and contribute to ecosystem carbon (C) sequestration. In this study, we investigated the global patterns and main driving factors of plant N uptake for different forms of N. The results are i... Nitrogen (N) is the primary nutrient element limiting the growth and productivity of terrestrial plants. Elucidating plant N acquisition is crucial for understanding plant N strategies and ecosystem productivity.Based on the global-scale 15N tracer studies about plant N uptake strategies, researchers found that globally, the average contribution...Read More -
2025-03-05Atmospheric nitrogen deposition has minor impacts on the abundance and diversity of arbuscular mycorrhizal fungi and their contribution to soil carbon stock in tropical forests① This field study and meta-analysis revealed that realistic levels of nitrogen (N) addition (≤50 kg N ha−1 yr−1) caused minimal changes in arbuscular mycorrhizal fungi (AMF) abundance and diversity, while high-level N addition (>50 kg N ha−1 yr−1) reduced AMF abundance and diversity. ② Current atmospheric N deposition is unlikely to enha... Knowledge about arbuscular mycorrhizal fungi (AMF) is crucial for understanding nutrient limitations on primary productivity and soil organic carbon (C) storage in terrestrial ecosystems. Both theoretical models and empirical evidence hold that nitrogen (N) addition in phosphorus-limited ecosystems can either increase or decrease AMF diversity a...Read More -
2025-03-05Contribute a Tansley Insight review on the topic of coevolution between plants and their cryptic pollinatorsObligate pollination mutualisms are ideal models for studying coevolution. This review discusses the interacting patterns, co-adaptations, and coevolution in two pollination mutualisms characterised by reciprocal adaptations between cryptic insects and their host plants. The pollination mutualisms between plants and animals play a crucial role in maintaining biodiversity, ecosystem services, and agricultural productivity. Nocturnal insects, which typically visit flowers at night, are often overlooked due to their activity during low-light conditions and outside of standard human activity cycles. However, the pol...Read More
