2023-12-29Impacts of record-breaking compound heatwave and drought events in 2022 China on vegetation growth2022 summer record-breaking heatwaves and droughts on vegetation growth .Cumulative intensity , especially in the Yangtze River basin , Tibetan Plateau , and Northern China . Moreover , heatwaves often occur with concurrent droughts .Climates simultaneously in the 2022 summer . The frequency and intensity of heatwaves and droughts have increased globally in the past several decades and are likely to continue to grow with future global warming. In the summer of 2022, China experienced a series of record-breaking heatwaves and unprecedented low rainfall-induced droughts across much of China’s regions. Vegetation growth ...Read More -
2023-12-26Blue carbon gain by plant invasion in saltmarsh overcompensated carbon loss by land reclamationRevealed that the invasion of exotic cordgrass , Spartina alterniflora , greatly increased the regional blue C storage , mainly by the seaward expansion.Large implications for blue C sinks .For the detailed information , please see https : / / doi . org / 10.1007 / s44246-023 - 00070 - 4.Read More
Saltmarsh is a major contributor to global blue carbon (C) sink. However, plant invasion and anthropic activities have greatly altered its distribution and its blue C function in the last decades. We used remote sensing and data synthesis to investigate how the four decades of plant invasion and land reclamation affect the spatiotemporal va... -
2023-12-24Long-term warming increased carbon sequestration capacity in a humid subtropical forestTropical and subtropical forests play a crucial role in global carbon ( C ) pools , and their responses to warming can significantly impact C-climate feedback and predictions of future global warming .Schematic of the C cycle in tropical forests under short ( blue font ) and long-term ( red font ) warming . ？ Values in boxes are percent changes... Tropical and subtropical forests play a crucial role in global carbon (C) pools, and their responses to warming can significantly impact C-climate feedback and predictions of future global warming. Despite earth system models projecting reductions in land C storage with warming, the magnitude of this response varies greatly between models, part...Read More -
2023-12-20Blue carbon sink capacity of mangroves determined by leaves and their associated microbiomeEcosystems , play a pivotal role in global carbon capture and storage .However , the mechanisms governing microbial-mediated carbon transformation from leaves.To the blue carbon pool during mangrove afforestation remain unclear .On the blue carbon sink capacity in mangroves .Dr . Zhe Lu , an associate professor from South China Botanical Garden ... Mangroves, recognized as critical blue carbon ecosystems, play a pivotal role in global carbon capture and storage. However, the mechanisms governing microbial-mediated carbon transformation from leaves to the blue carbon pool during mangrove afforestation remain unclear. Addressing this gap, Dr. Zhe Lu, et al. investigate mangrove leaf DOM char...Read More -
2023-11-21Long-term field translocation differentially affects arbuscular mycorrhizal and ectomycorrhizal trees in a sub-tropical forestArbuscular mycorrhizal ( AM ) and ectomycorrhizal ( EcM ) trees are commonly represented in tropical forests , but their response to warming is generally not known .Translocation treatment was more beneficial for the growth of AM trees than EcM trees , while EcM trees were more tolerant of soil water deficit .The Key-Area Research and Developmen... Arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) trees are commonly represented in tropical forests, but their response to warming is generally not known. We conducted a long-term (9-year) field experiment in subtropical China by translocating AM tree species (Machilus breviflora and Schima superba) and EcM tree species (Syzygium rehderianu...Read More -
2023-11-06Transgenic lettuce producing EHEC O157: H7 antigen EspB or γ-intimin C280 is effective as an oral vaccineA subset of the Shiga toxin-producing food-borne pathogen that causes diarrhea , hemorrhagic colitis and hemolytic uremic syndrome . ？ The reservoirs of EHEC O157 : H7 are.Genes driven by lettuce ubiquitin promoter were found able to produce antigens genetically stably . ？ In these transgenic lines , younger leaves.Mice oral immunization assay... Enterohemorrhagic Escherichia coli (EHEC) O157: H7 is a subset of the Shiga toxin-producing food-borne pathogen that causes diarrhea, hemorrhagic colitis and hemolytic uremic syndrome. The reservoirs of EHEC O157: H7 are ruminants, mainly bovine. Bovine vaccination has been used to prevent disease outbreaks, and the current method relies on va...Read More -
2023-11-06Understanding recreational ecosystem service supply-demand mismatch and social groups’ preferences: Implications for urban–rural planningRecreation in nature provides multiple physical and mental health benefits to residents .Spatially quantified the recreation service supply and demand along urban-rural gradients in Beijing-Tianjin-Hebei region and revealed the heterogeneous preferences of different population groups . ？ ？ The study found recreation service imbalance with high... Recreation in nature provides multiple physical and mental health benefits to residents. People in cities, especially large ones, have high demand for natural landscape for recreational purposes. However, these natural landscapes often assemble in rural areas. Considering the mismatch of recreation service supply and demand will provide useful i...Read More -
2023-10-22An earlier start of growing season can affect tree radial growth through regulating cumulative growth rateProfoundly affecting phenology , especially in the Northern Hemisphere .Tree radial growth through decreasing the cumulative growth rate .In general , we determined that an earlier SoGS influences tree radial growth by regulating.And red arrows representing negative and positive effects , respectively .Read More
Climate change is profoundly affecting phenology, especially in the Northern Hemisphere. Nevertheless, how tree radial growth responds to phenological shifts remains to be explored. The boreal forest in the Northern Hemisphere is one of the largest biological communities on Earth, and its tree growth dynamics are significant for global chan...
