Keyword:  现代介形类海岸带阿拉斯加北端;
Abstract: 本文主要对北极阿拉斯加巴罗地区海岸带中的现代介形类动物群特征及其生态环境进行了探讨,其中在盐度为0.157-4.41 g/l的河口和近河口段的河流沉积中发现Elofsonia susitnensis Forester et Brouwers和Cytheromorpha knikensis Forester et Brouwers的活体。据报道,这两种介形类活体过去见于59°-61°N、盐度为1.112-32.5 g/l的阿拉斯加湾及其沿岸带,在白令海、波弗特海未见及。作者在纬度更北、盐度更低的水域发现它们,这对北极介形类动物群研究以及控制介形类分布的环境参数的研究都提供了新认识。同时根据介形类分布特征,划分出4个介形类生态组合。
