Water mites are important constituents of aquatic ecosystems, but their biodiversity is poorly understood. The goal of this study was to improve knowledge of water mite assemblages in the Detroit River through combined use of morphological and cytochrome oxidase I (COI) DNA barcode data and to elucidate seasonal water mite diversity. The diversity of water mites collected from Blue Heron Lagoon at Belle Isle, an island in the Detroit River, is described. Novel DNA barcodes for Albia, Hydrochoreutes, Madawaska, and Axonopsis are reported with a species level barcode for Lebertia. Novel DNA barcodes may represent the presence of previously undescribed variants or new species of several genera. The prevalence of water mites is higher in the summer, but a different pattern is observed for diversity. The diversity of water mites, by several measures, varies seasonally with lower diversity in summer and winter months and higher diversity during seasonal transitions. For these organisms, we interpret seasonal change as an intermediate disturbance resulting in increased biodiversity.

螨虫组合揭示了不同的属，新颖的DNA条码和中间干扰的过渡时期

螨是水生生态系统的重要组成部分，但对其生物多样性的了解却很少。这项研究的目的是通过结合使用形态学和细胞色素氧化酶I（COI）DNA条码数据来提高底特律河中水螨组合的知识，并阐明季节性水螨的多样性。描述了从底特律河小岛美女岛的蓝鹭泻湖收集的水螨的多样性。为新的DNA条形码Albia，Hydrochoreutes，马达沃斯卡，和Axonopsis报道有用于物种水平条形码Lebertia。新的DNA条形码可能代表先前未描述的变体或几个属的新物种的存在。夏季，水螨的患病率较高，但多样性却观察到不同的模式。通过几种方法，水螨的多样性随季节而变化，夏季和冬季月份的多样性较低，而在季节性过渡期间的多样性较高。对于这些生物，我们将季节变化解释为导致生物多样性增加的中间干扰。
