Abstract

Abstract The Amphizoidae, Dytiscidae, Gyrinidae and Haliplidae (Coleoptera: Adephaga of Alaska (USA) and the Yukon Territory (Canada) were surveyed during the years 1994, 2016, 2017 and 2019. By adding specimens collected through the Arctic Shorebird Demographic Network survey and those from the collection of the University of Alaska, Fairbanks, a total of 5305 individuals are newly reported, which substantially expand our distributional knowledge of these families from the Alaska-Yukon region. Seventeen species are newly reported from Alaska; three from the Yukon Territory. Following this study 160 species are now recorded for the Alaska-Yukon region (136 in Alaska and 138 in Yukon territory). The Nearctic component of the fauna is made up of 103 species (64.4%), the Holarctic component of 57 species (35.6%). Most species (103, 64.4%) have a transcontinental distribution and are characteristic of the boreal and/or arctic ecozones whilst 57 species (35.6%), are recognised as species with western affinities. Eleven species are considered Beringian.

阿拉斯加育空地区的Hydradephaga（鞘翅目：两栖动物科、双足目、Gyrinidae、Haliplide）：新记录、分布和动物群组成

摘要对1994年、2016年、2017年和2019年美国阿拉斯加州和加拿大育空地区的两栖科、蝼蛄科、蝼蛄科和蝼蛄科(鞘翅目:蝼蛄)进行了调查。通过北极滨鸟人口统计网络调查和阿拉斯加大学费尔班克斯收集的标本，新报告的标本总数为5305只，这大大扩展了我们对阿拉斯加-育空地区这些家庭的分布知识。阿拉斯加新报道了17种;三个来自育空地区。在这项研究之后，现在在阿拉斯加-育空地区记录了160个物种(阿拉斯加136个，育空地区138个)。新北极区有103种(64.4%)，全北极区有57种(35.6%)。大多数物种(103,64.4%)具有跨大陆分布，具有北方和/或北极生态带的特征，而57种(35.6%)被认为具有西部亲缘关系。11种被认为是白令陆生的。

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
