Abstract

The microdiversity of cenotes in the Yucatan Peninsula, Mexico has been little studied, with the phytoplankton and protists being the most representative species. However, all previous studies have been focused on cenotes associated with touristic activities, leaving a gap in the understanding of cenotes located within urban areas. The present study is dedicated to the identification of phytoplankton and protists in the cenotes of Cancun, Quintana Roo, Mexico. We conducted our research in four urban cenotes, collecting samples using a 150 µm plankton net, filtering them with a 45 µm membrane, and examining them under optical microscopy. Subsequently, we calculated the abundance, richness, and completeness of the samples. Our findings revealed a total of 6 phyla, 4 subphyla, 10 classes, 8 subclasses, 15 orders, 15 families, 18 genus, and 17 species and 4 species indeterminata in the cenotes of Cancun, Quintana Roo, Mexico. Among these, there were 8 species of phytoplankton and 1 species indeterminata, while 9 species of protists and 3 species indeterminata. These results highlight the remarkable species richness and the complex structure and composition of urban cenotes, suggesting that some species may be unique to this particular ecosystem. Currently, there is limited knowledge regarding the behavior of these aquifers (urban cenotes), and a comprehensive inventory or characterization of their microdiversity is lacking. Such information could be instrumental in the management, conservation, and sustainable use of these valuable aquifers.
Aquatic墨西哥金塔纳罗奥州坎昆城市天然井的微多样性
墨西哥尤卡坦半岛天然井的微多样性研究很少,浮游植物和原生生物是最具代表性的物种。然而,以往的所有研究都集中在与旅游活动有关的天然井上,对位于城市地区的天然井的理解存在空白。本研究致力于墨西哥坎昆金塔纳罗奥州天然井中浮游植物和原生生物的鉴定。我们在四个城市天然井中进行了研究,使用150微米的浮游生物网收集样本,用45微米的膜过滤,并在光学显微镜下检查。随后,我们计算了样品的丰度、丰富度和完整性。在墨西哥昆塔纳罗奥州坎昆天然井共发现6门4亚门、10纲8亚纲、15目15科18属、17种和4种未确定种。其中浮游植物8种,不确定种1种,原生生物9种,不确定种3种。这些结果突出了城市天然井显著的物种丰富度和复杂的结构和组成,表明一些物种可能是这个特定生态系统所特有的。目前,关于这些含水层(城市天然井)的行为的知识有限,并且缺乏对其微多样性的全面调查或表征。这些资料可有助于管理、保护和可持续利用这些宝贵的含水层。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
