The plant species richness index is not positive relevant to species evenness index for which represents the evenness extent of species distribution instead of the quantity of species.
物种丰富度指数与均匀度指数并非存在正相关关系,均匀度指数反映的是物种分布的均匀程度,并不反映其物种数量的多少。
But the research by Crowder, an insect ecologist at Washington State University in Pullman, and his colleagues, shows the importance of 'evenness' - the relative abundance of different species.
但是华盛顿州立大学的昆虫生态学家克劳德的研究显示平衡的重要性——各种物种相对充盈。
Species richness and evenness were unrelated to similarity in species composition.
物种丰富度和均匀度均与物种构成上的相似性没有显著相关关系。
Both the species richness and the abundance of predacious and neutral insects were relatively smaller, but predators had the highest evenness index.
捕食性和中性昆虫的种类和数量相对较少,但捕食者的均匀度最高。
