这篇研究通过分析颤杨(Populus tremuloides)的15个不同基因型（包括二倍体和三倍体）在海拔梯度上的叶片功能性状变异，揭示了叶片经济谱(LES)在种内尺度上的松弛现象。研究发现基因型、细胞型(cytotype)和昆虫食草压力共同影响性状-性状和性状-环境关系，表明种内 ...

• Dioecious species represent an important component of terrestrial ecosystems, but little is known about gender-specific responses to elevated atmospheric CO2. • In an open-top chamber experiment ...

Trembling aspen (Populus tremuloides) is a clonal tree species, which regenerates mostly through root suckering. In spite of vegetative propagation, aspen maintains high levels of clonal diversity. We ...
