BACKGROUND
Testate amoebae are a polyphyletic group of protists living preferentially in soils, freshwaters and wetlands. These Protozoa have a worldwide distribution, but their presence and diversity in the Azores (a remote oceanic archipelago) is poorly known, with only twelve taxa recorded so far. The published information reflects occasional collections from sporadic field visits from naturalists to São Miguel Island, mainly in the nineteenth century. To overcome this limitation, a standardised survey was carried out on the Island, sampling different types of habitats from several localities to provide the distribution and information on species ecology of testate amoebae.
NEW INFORMATION
In this study, 43 species of testate amoebae were recorded (within a total of 499 occurrences), belonging to two orders of Protista (26 Arcellinida and 17 Euglyphida). The most frequently occurring testate amoebae were , , , and . The most diverse genus was (six species). A total of 38 species are new records for the Azores Archipelago. These data help to improve knowledge of the geographical distribution of testate amoebae in the northern hemisphere and their diversity in the Azores Archipelago.
背景
有壳变形虫是一类多源的原生生物，主要生活在土壤、淡水和湿地中。这些原生动物分布于全球，但它们在亚速尔群岛（一个偏远的海洋群岛）的存在情况和多样性却鲜为人知，迄今为止仅记录了12个分类单元。已发表的信息反映了博物学家主要在19世纪对圣米格尔岛进行的零星实地考察中的偶然采集。为克服这一局限性，在该岛开展了一项标准化调查，从多个地点对不同类型的栖息地进行采样，以提供有壳变形虫的分布情况和物种生态信息。
新信息
在本研究中，记录了43种有壳变形虫（共499次出现），属于原生生物的两个目（26种属于表壳目，17种属于真壳目）。最常见的有壳变形虫是 、 、 、 和 。最多样化的属是 （六种）。共有38个物种是亚速尔群岛的新记录。这些数据有助于增进对北半球有壳变形虫地理分布及其在亚速尔群岛多样性的了解。
