物种多样性能否指示基因多样性？ 已有2人参与

一直以来，默认物种多样性能作为基因多样性的一个替代指标，但是事实上如何呢？ 看看ecology letters上的一篇最新文章，利用高山植物的相关资料，结果表明： The Convention on Biological Diversity (CBD) aims at the conservation of all three levels of biodiversity, that is, ecosystems, species and genes. Genetic diversity represents evolutionary potential and is important for ecosystem functioning. Unfortunately, genetic diversity in natural populations is hardly considered in conservation strategies because it is difficult to measure and has been hypothesised to co-vary with species richness. This means that species richness is taken as a surrogate of genetic diversity in conservation planning, though their relationship has not been properly evaluated. We tested whether the genetic and species levels of biodiversity co-vary, using a large-scale and multi-species approach. We chose the high-mountain flora of the Alps and the Carpathians as study systems and demonstrate that species richness and genetic diversity are not correlated. Species richness thus cannot act as a surrogate for genetic diversity. Our results have important consequences for implementing the CBD when designing conservation strategies. 来源： http://cn.onlinelibrary.wiley.com/doi/10.1111/ele.12004/abstract |
