谁来帮忙翻译下:the factors that control the diversity of communities
have been a fundamental problem of ecology nearly since its start.(前一句的补充完整)
主要是不懂community这个单词在这个句子的意思,并不是“社区”的意思,而应该是跟生物和生物种类有关的词吧..

community
生物学名词就是
[C] (biology生)
a group of animals or plants living or growing in the same place
(动植物的)群落.
