目前普遍观察到的生物多样性对生产力的促进作用可能是由于多样性促进了树木生长或提高了存活率。中国科学院植物研究所研究员马克平团队等利用建立在我国亚热带地区的大型森林生物多样性控制实验从第三年到第十二年的个体存活数据集,评估了从单种到16个物种的不同多样性样方中物种丰富度、功能性状以及年际气候对树木存活率的影响。
中国地质大学(武汉)专家牵头的联合团队用生态计算模拟技术研究,揭示大灭绝中生物多样性锐减或为生态系统坍塌前兆。相关研究成果近日发表在国际知名期刊《当代生物学》上。记者从中国地质大学(武汉)陈中强教授团队获悉,该团队联合美英等国科研机构,用生态计算模拟技术,对2.
Abstract:Here, with the prerequisite pieces at our disposal, namely a method to generate vortices in dipolar gases and supersolids with two-dimensional crystalline order, we report on the theoretical investigation and experimental observation of vortices in the supersolid phase . Our work reveals a fundamental difference in vortex seeding dynamics between unmodulated and modulated quantum fluids. This opens the door to study the hydrodynamic properties of exotic quantum systems with numerous spontaneously broken symmetries, in disparate domains such as quantum crystals and neutron stars.
