The effects of environmental change on biodiversity are still poorly understood. In particular, the consequences of shifts in species composition for marine ecosystem function are largely unknown. Here we assess the loss of functional diversity, i.e. the range of species biological traits, in benthic marine communities exposed to ocean acidification (OA) by using natural CO2 vent systems. We found that functional richness is greatly reduced with acidification, and that functional loss is more pronounced than the corresponding decrease in taxonomic diversity. In acidified conditions, most organisms accounted for a few functional entities (i.e. unique combination of functional traits), resulting in low functional redundancy. These results suggest that functional richness is not buffered by functional redundancy under OA, even in highly diverse assemblages, such as rocky benthic communities.

沿自然二氧化碳梯度的功能性生物多样性丧失。

环境变化对生物多样性的影响仍然知之甚少。特别是,物种组成变化对海洋生态系统功能的影响在很大程度上尚不清楚。在这里,我们使用天然CO 2排放系统评估了暴露于海洋酸化(OA) 的底栖海洋群落中功能多样性的丧失,即物种生物特征的范围。我们发现,酸化后功能丰富度大大降低,并且功能损失比相应的分类多样性下降更明显。在酸化条件下,大多数生物体只具有少数功能实体(即功能性状的独特组合),导致功能冗余度较低。这些结果表明,即使在高度多样化的组合中,例如岩石底栖群落,功能丰富度也不会被 OA 下的功能冗余所缓冲。
