2016年夏季，研究了环境因子对科尔盖伦高原南部浮游动物水平群落结构的影响。浮游动物丰度在1490~363,484 ind之间。1000m(-3)，东部和中部地区最多。在聚类分析的基础上，将浮游动物划分为6个类群(A-F)，这些类群仅根据水团和锋面系统进行区分。A-C组浮游动物丰富，与叶绿素a浓度高的区域一致。D组代表南极南部绕极海流锋面附近的低丰度，E组聚集在南部边界以南，F组由福恩海槽以东的两个站组成。广义线性模型(GLM)强调前沿和叶绿素a浓度是浮游动物总体分布的驱动因素。然而，关键物种的种群结构更有可能是物种特有的生命周期的结果，而不是水团和锋面系统的结果。
The influence of environmental factors on the horizontal community structure of zooplankton over the southern Kerguelen Plateau was investigated during summer in 2016. Zooplankton abundance ranged from 1490 to 363,484 ind. 1000 m(-3), with highest numbers observed in the eastern and central areas. Based on cluster analysis the zooplankton were divided into six groups (A-F), and these were only distinguished based on water masses and frontal systems. Groups A to C had abundant zooplankton and were consistent with areas of high chlorophyll a concentration. Group D represented low abundance near the southern Antarctic Circumpolar Current front, while group E was clustered south of the Southern Boundary and group F comprised two stations to the east of the Fawn Trough. Generalised linear model (GLM) highlighted both fronts and chlorophyll a concentration as drivers of overall zooplankton distribution. However, the population structures of key species were more likely a result of species-specific life cycles rather than water masses and frontal systems.
