Cladocera (Crustacea: Branchiopoda) quickly respond to changes in environmental conditions and their remains are usually found in large amounts in lacustrine sediments, which make them an important biological proxy in paleolimnological studies. Variations in species composition have been used to infer paleo-climate and paleo-environmental variables including lake depth, eutrophication, and deforestation. However, despite their advantages as bioindicators in the study of past conditions, they are underutilized in paleolimnological research in Central America due to limited knowledge about their diversity and the morphological differences between the subfossil remains of different taxa. In order to address this issue, we described and analyzed cladoceran remains from 56 waterbodies located in Mexico, Guatemala, El Salvador, and Honduras. Here, we provide a description of the remains from 10 different taxa that belong to the Sididae, Bosminidae, Daphniidae, Macrothricidae, and Ilyocryptidae families.

从中美洲和墨西哥尤卡坦半岛的湖泊沉积物中鉴定亚化石非乳糜状枝角类（甲壳纲：鳃足目）的指南：第一部分

枝角目（甲壳纲：鳃足目）对环境条件的变化做出快速反应，它们的遗骸通常大量存在于湖泊沉积物中，这使它们成为古湖泊学研究中的重要生物代表。物种组成的变化已被用于推断古气候和古环境变量，包括湖泊深度、富营养化和森林砍伐。然而，尽管它们在过去条件研究中作为生物指示剂具有优势，但由于对它们的多样性和不同分类群的亚化石遗骸之间的形态差异的了解有限，它们在中美洲的古湖泊学研究中并未得到充分利用。为了解决这个问题，我们描述和分析了位于墨西哥、危地马拉、萨尔瓦多和洪都拉斯的 56 个水体的枝角类动物遗骸。这里，
