植物适应性遗传与环境交互作用及光谱变异研究|遗传可塑性|光谱特征分离|环境驱动效应|遥感监测技术 全球范围内，随着植物适应速度难以跟上温度上升的步伐，植被生物多样性预计将会下降。为了通过遥感技术支持保护工作，我们区分了遗传因素和环境因素 ...

本研究通过31年长期实验，揭示杂交渐渗(hybrid introgression)作为河岸树种(Populus fremontii和P. angustifolia)应对气候变化的快速进化机制。研究发现低海拔P. fremontii基因通过RFLP-1286等标记向高海拔P. angustifolia的渐渗显著提高75%存活率，为气候变化下生态系统适应性进化 ...

Fremont cottonwood (Populus fremontii) is an early successional foundation species found in riparian forest ecosystems in the North American Southwest. Along rivers, the upper limit of the seedling ...

John C. Fremont fed his horses the inner bark of cottonwood trees during a brutal winter in Reno. Snow in the Sierras prevented him reaching California for many months. The trees would later be dubbed ...
