2023/6/19
Grow a tomato inside a square box, and you’ll end up with a square tomato. It’s an experiment that shows clearly how confinement can influence a body’s evolving shape.
Size-dependent species richness:trends within plant communities and across latitude
Community ecology plant size species packing species richness
2015/8/27
We examine how species richness and species-specific plant density (number of species and number of individuals per species, respectively) vary within community size frequency distributions and across...

薇甘菊 草本植物 木本植物 光合能力 反射率 透射率
2009/11/18
该文对薇甘菊及其所在群落内19种植物(草本和木本)的叶片透射率、反射率和光合特征指标进行了测定, 结果表明:薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近, 在各个光学特征指标与光合相关指标的相互关系中, 薇甘菊并没有表现出区别于同一群落内其它植物的特征。从平均值来看, 200-800 nm下叶片反射率和透射率由大到小依次为: 薇甘菊>草本植物>木本植物, 薇甘菊各光学植被指标(SR680、S...
