1Arsenic in Rice Soils and Potential Agronomic Mitigation Strategies to Reduce Arsenic Bioavailability: A Review显示文摘Soils used for rice(Oryza sativa L.) cultivation in some areas contain high concentrations of arsenic(As) due to irrigation with groundwater containing As and intensive use of agrochemicals or industrial residues containing As. To restrict rice uptake of As in these soils, approaches to reduce As input and bioavailability must be considered. One approach to reduce As input into rice soils or uptake by rice is cultivating rice under aerobic, intermittent flooding, or alternate wetting and drying(AWD) conditions, rather than in submerged soils, or use of irrigation water low in As. For reducing As bioavailability in soil, aerobic or AWD rice culture and application of biochar, sulfur(S), and/or rice polish to soil are promising. Moreover, use of As-hyperaccumulating plant species(e.g.,Pteris vittata L.) in rotation or combinations with favourable plant species(e.g., Azolla, Chlorella, or Nannochloropsis species) can also be promoted, in addition to using rice cultivars that are tolerant to As. Though applications of high doses of phosphorus(P), iron(Fe), and silicon(Si) fertilizers have shown promise in many instances, these methods have to be practiced carefully, because negative effects have also been reported, although such incidents are rare. Major factors affecting As speciation and bioavailability in soil are chemical properties such as redox status, p H, and Fe, P, Si, and S concentrations, physical properties such as texture and organic matter, and biological properties such as methylation activity by soil microorganisms. However, as many of these factors interact,long-term examination under field conditions is needed before measures are recommended for and implemented in farmers' fields.Lalith D.B.SURIYAGODA Klaus DITTERT Hans LAMBERS 2018Pedosphere2018,28,3:6
2植物养分捕获策略随成土年龄的变化及生态学意义显示文摘自然成土过程中土壤养分的变化与植被原生演替常同时发生。随成土年龄变化的植物养分捕获策略(NASs)对植物竞争能力和演替过程具有重要影响。该文将植物NASs划分为细根、微生物、特殊根系、食虫和寄生策略等5个类型;发现植物NASs的多样性随成土年龄的增加呈哑铃型变化模式;特殊根系策略对植物捕获养分的作用在成土中期最小、后期最大,细根和微生物策略的作用随成土年龄的增加逐渐降低;分析了成土过程中NASs对植物种间关系影响的变化,发现NASs对成土早期植物的促进作用和中期的竞争关系具有重要影响,而成土后期多样和互补的NASs对植被群落的稳定共存及多样性的形成具有影响;提出应进一步探究成土过程中土壤养分与植物NASs变化之间的定量关系,开展更多研究以阐明NASs对植被原生演替、物种多样性形成和成土过程的贡献与机理。李孝龙 周俊 彭飞 钟宏韬 Hans LAMBERS 2021植物生态学报2021,45,7:3

4Nutrient resorption from senescing leaves of epiphytes,hemiparasites and their hosts in tropical forests of Sri Lanka显示文摘Aims Epiphytes and hemiparasites do not have direct access to soil nutri-ents.Epiphytes acquire nutrients through symbiosis,foliar leachates and throughfall,whilst hemiparasites have specialized structures(haustoria)to acquire nutrients from their host.Irrespective of the green leaf nutrient concentrations of epiphytes,hemiparasites and their hosts,nutrient-resorption efficiency and proficiency are expected to be the greater in epiphytes than in their hosts and in hemiparasites.These hypotheses were tested.Methods Green and senescing leaves of epiphytes(n=23),hemiparasites(n=9)and their hosts were collected,and leaf area,leaf dry weight,nutrient(nitrogen-N,phosphorus-P,potassium-K,calcium-Ca)and sodium(Na)concentrations were measured,and resorption effi-ciency(%)and proficiency were calculated.Important Findings Concentrations of N,P,K,Ca and Na in green leaves of epiphytes and hemiparasites were either similar or greater than those of their hosts,except for lower green leaf N concentration in hemiparasites.Epiphytes resorbed N,P,K and Na,while their hosts resorbed only N,P and K.Hemiparasites and their hosts resorbed P,K and Na while N was not resorbed.Overall,resorption efficiency was great-est in epiphytes>hemiparasites=hosts,while the resorption pro-ficiencies were similar or greater for epiphytes and hemiparasites compared with their hosts,except for N in hemiparasites.Relatively high nutrient concentrations in epiphytes were associated with greater resorption efficiency.Understanding contrasting nutrient concentrations in epiphytes,hemiparasites and their hosts will be important in recognising their contribution to ecosystem nutrient cycling.Lalith D.B.Suriyagoda Ranil Rajapaksha Gamini Pushpakumara Hans Lambers 2018Journal of Plant Ecology2018,11,6:2
5Revisiting mycorrhizal dogmas:Are mycorrhizas really functioning as they are widely believed to do?显示文摘Since the discovery of mycorrhizas,dogmas have been developed regarding their function,ecology,and distribution.We explore if these dogmas are valid,and if there are research biases toward regions inhabited by most researchers and away from regions inhabited by most plant species.We found,first,that the mycorrhizal status is known in less than 1%of plant species,with few having proven mycorrhizal benefits for growth and development.Second,the mycorrhizal status of a plant species varies within families,even genera.Third,mycorrhizas are important for phosphorus acquisition only within a narrow phosphorus range.Fourth,mycorrhizal plants are not uniform in their response to environment;taxonomy,phylogeny and continental history strongly drive mycorrhizal diversity.For example,the center of diversification of Ericaceae and Orchidaceae is in the neotropics,rather than,as recently claimed,in cold and high-latitude climates.Understanding the importance of mycorrhizas at the family-wide and biome-wide level is therefore conflicted by a research bias toward research-intensive regions outside the phylogenetic hotspots of diversification.The current precepts on mycorrhizas provide important starting points for hypotheses to robustly test when and where mycorrhizas play a role in determining ecological trajectory.The time has come to move forward and revisit past assumptions and update the dogmas,rather than assume functional significance in terms of nutritional benefits from studies on extraneous regions and species.We conclude that non-nutritional benefits deserve far greater attention.Felipe E.Albornoz Kingsley W.Dixon Hans Lambers 2021Soil Ecology Letters2021,3,1:2
