Abstract

The ecological landscape of Caribbean reefs is rapidly changing as octocorals fill the void left by declining scleractinian populations. Effective molecular barcodes are necessary to accurately identify these octocorals and monitor this shifting ecosystem. We tested the efficacy of the as a barcode compared to the most commonly used barcode on a collection of octocorals from across the Caribbean. Based on pairwise genetic distance values, appeared to be more effective at differentiating species within the families Plexauridae and Gorgoniidae, while was slightly more effective at distinguishing species of Pterogorgiidae. However, the standard rDNA primers did not amplify all species as effectively as , especially those belonging to the genus . A shorter barcode developed for eDNA applications distinguished species as effectively as the complete barcode.

摘要

随着八放珊瑚填补石珊瑚种群数量下降所留下的空白，加勒比珊瑚礁的生态景观正在迅速变化。有效的分子条形码对于准确识别这些八放珊瑚并监测这一不断变化的生态系统至关重要。我们将[未提及的某种条形码]作为条形码与最常用的[未提及的某种条形码]进行比较，测试了其在一组来自加勒比地区的八放珊瑚上的功效。基于成对遗传距离值，[未提及的某种条形码]在区分软珊瑚科和柳珊瑚科内的物种时似乎更有效，而[未提及的某种条形码]在区分翼柳珊瑚科的物种时略更有效。然而，标准的[未提及的某种]核糖体DNA引物对所有物种的扩增效果不如[未提及的某种条形码]，尤其是那些属于[未提及的某种属]的物种。为环境DNA应用开发的较短的[未提及的某种条形码]在区分物种方面与完整的[未提及的某种条形码]同样有效。
