中科院动物研究所戈峰研究员领导的种群生态与全球变化研究组模拟未来大气CO2浓度升高到750ppm的环境,以豆科植物蒺藜苜蓿和模式昆虫豌豆蚜为研究对象,利用固氮缺失型与野生型苜蓿为研究材料,从植物的固氮作用、氨基酸代谢、以及豌豆蚜的种群适合度、行为特征及其分子调控机制等方面,系统研究了豌豆蚜如何通过植物的固氮作用来调节利用植物的氮素营养从而适应CO2浓度升高。该研究在线发表在Global Change Biology。氮素作为昆虫生长发育的限制因素,其含量受到CO2浓
The Group of Population Ecology and Global Change led by researcher Ge Feng, Institute of Zoology, Chinese Academy of Sciences simulated the atmospheric CO 2 concentration in the future increased to 750ppm environment. With Medicago truncatula and the model insects pea aphid as the research object, the nitrogen fixation deficient and wild type Medicago sativa as a research material, from nitrogen fixation in plants, amino acid metabolism, as well as pea aphid population fitness, behavioral characteristics and molecular regulation mechanisms, such as the pea aphid nitrogen fixation through the plant to regulate the use of plant nitrogen Nutrition to adapt to CO2 concentration. The study is published online at Global Change Biology. Nitrogen as a limiting factor for insect growth and development, its content by CO2 concentration
