Abstract

As a result of studying different populations of crustaceans of the genus Eurytemora Giesbrecht from the inland water bodies of the basins of the White Sea, the Pechora Sea, the Lena River delta, and Pacific coast of the United States, the species Eurytemora gracilicauda Akatova 1949 has been found along the entire northern border of the Russian Eurasia, while North American E. americana Williams 1906 has not been registered within these limits. Clear morphological and molecular genetic differences between E. gracilicauda and E. americana are presented.

摘要

由于研究了白海，佩乔拉海，利纳河三角洲和美国太平洋沿岸内陆水体的Eurytemora Giesbrecht属甲壳动物的不同种群，Eurytemora gracilicauda Akatova物种1949沿俄罗斯欧亚大陆的整个北部边界被发现，而北美E. americana Williams 1906尚未在这些范围内注册。介绍了E. gracilicauda和E. americana之间明显的形态和分子遗传差异。
