至少在温带地区,最大的多样性通常出现在演替中期,而不是在顶极群落中。
At least in temperate zones, maximum diversity is often found in mid-successional stages, not in the climax community.
因此,从多样性的角度来看,将一种主要捕食者从一个群落中彻底消灭通常是一个错误。
Therefore, from the stand point of diversity, it is usually a mistake to eliminate a major predator from a community.
当季节变得更分明,植物群落逐渐分开,也就意味着任何一个特定的地区的植物种类多样性都会降低。
When the seasons became more distinct, the plant communities were pulled apart, that meant, in any given area, there was less plant diversity.
支持这一观点的是,长期存在的顶极群落通常比先锋群落有更复杂的食物网和更多的物种多样性。
Support for this idea came from the observation that long-lasting climax communities usually have more complex food webs and more species diversity than pioneer communities.
