At Palmyra Atoll, the eDNA signal on tidal sand flats was associated with fish biomass density and captured 98-100% of the expected species diversity there. Although eDNA spilled-over across habitats, species associated with reef habitat contributed more eDNA to reef sites than to sand-flat sites, and species associated with sand-flat habitat contributed more eDNA to sand-flat sites than to reef sites. Tides did not disrupt the sand-flat habitat signal. At least 25 samples gives a coverage > 97.5% at this diverse, tropical, marine system. This article is protected by copyright.

在巴尔米拉环礁，鱼类群落的环境 DNA 信号会随着栖息地的变化而变化，但不会随潮汐变化

在巴尔米拉环礁，潮汐沙滩上的 eDNA 信号与鱼类生物量密度相关，并捕获了那里 98-100% 的预期物种多样性。尽管 eDNA 溢出到整个栖息地，但与珊瑚礁栖息地相关的物种对珊瑚礁遗址的贡献比对沙坪遗址的贡献更多，与沙坪栖息地相关的物种对沙坪遗址的贡献比对珊瑚礁遗址的贡献更多。潮汐并没有破坏沙地栖息地的信号。在这个多样化的热带海洋系统中，至少有 25 个样本的覆盖率 > 97.5%。本文受版权保护。版权所有。
