Despite limited access and rather deficient sampling in many lowland areas of eastern Ecuador, scientists have been able to demonstrate that this specific region of Amazonia houses extraordinarily high concentrations of species within several taxa - terrestrial and aquatic, plant and animal, vertebrate and invertebrate.
In this work, we developed an updated list of the ichthyofauna of the Yasuní National Park (YNP), based on an extensive literature review and databases of the most representative ichthyological collections from Ecuador. Our results yielded 458 species of freshwater fishes distributed in 47 families and 13 orders. This number exceeded previous fish lists from YNP and accounts for a considerable proportion of species inhabiting the Napo River Basin as well as the entire Amazon River Basin.The higher-than-previously-reported species diversity within this protected area, the services these species provide to humans and the absence of invasive species underscore the need for greater efforts and investment in protecting and managing western Amazonian lands and waters.
尽管在厄瓜多尔东部的许多低地地区获取样本的机会有限且样本相当不足，但科学家们已经能够证明，亚马逊地区的这一特定区域在几个分类群中拥有极高的物种浓度——包括陆地和水生、植物和动物、脊椎动物和无脊椎动物。
在这项工作中，我们基于广泛的文献综述以及厄瓜多尔最具代表性的鱼类学收藏数据库，编制了一份亚苏尼国家公园（YNP）鱼类区系的更新清单。我们的研究结果显示，有458种淡水鱼分布在47个科和13个目中。这个数字超过了之前YNP的鱼类清单，并且占纳波河流域以及整个亚马逊河流域栖息物种的相当大比例。该保护区内高于此前报告的物种多样性、这些物种为人类提供的服务以及没有入侵物种，都凸显了加大对亚马逊西部土地和水域保护与管理的努力和投资的必要性。
