我们使用大量的稳定同位素分析(SIA)研究昼夜摄食活动在两个垂直迁移的磷虾物种,Thysanoessa gregaria和Euphausia similis,澳大利亚东部。SIA表明,这两个物种在夜间的温跃层以上的喂养,可能对颗粒有机物和微型浮游动物。我们的研究结果支持使用SIA调查浮游动物的垂直迁移和摄食。
We used bulk stable isotope analysis (SIA) to examine diel feeding activity in two vertically migrating krill species, Thysanoessa gregaria and Euphausia similis, off eastern Australia. SIA indicated feeding by both species above the thermocline at night, potentially on both particulate organic matter and microzooplankton. Our results support the use of SIA to investigate vertical migration and feeding in zooplankton.
