科研人员在昆虫多样性对森林树种多样性与初级生产力关系的调控机制研究中取得重要进展
森林 树种多样性 生产力 昆虫多样性
2023/9/19
中国科学院植物研究所马克平研究组利用建立在我国亚热带地区的大型森林生物多样性与生态系统功能实验（BEF-China，江西德兴）连续多年的植物和昆虫的调查数据，评估了树种多样性对不同昆虫类群的作用及其对森林生产力的影响，以确定昆虫多样性对树种多样性-森林生产力关系的调控机制。结果发现，树种多样性对所有昆虫类群的物种多样性和多度均表现出一致的促进作用，且该影响随昆虫类群所处营养级的升高而减弱。进一步的...
国外绘制出昆虫完整大脑图谱
昆虫 大脑 完整图谱
2024/1/17
英国剑桥大学科研人员通过高分辨率电子显微镜切片扫描果蝇幼虫大脑，生成了完整的大脑图谱，显示了果蝇幼虫大脑中每一个神经元以及神经元之间的突触连接方式。该研究有助于理解大脑中神经信号传播引起的行为和学习机能原理。相关研究发表在《科学》杂志上。
