Abundance and distribution of coastal, inshore zooplankton in the Huon Estuary and D'Entrecasteaux Channel, Tasmania, Australia (2004-2005)

Mesozooplankton community composition and structure were examined throughout the DEntrecasteaux Channel, Huon Estuary and North West Bay, Tasmania, from November 2004 to October 2005. The composition of the mesozooplankton community was typical of inshore, temperate marine habitats, with seasonally higher abundance in summer and autumn and lower numbers in winter and spring. Copepods were the largest contributors to total abundance across all seasons and stations, while cladocerans and appendicularians were proportionally abundant in spring and summer. The faecal pellets of these three main groups, along with those of krill and amphipods, also contributed significantly to material recovered from sediment traps. Meroplanktonic larvae of benthic animals showed short-term peaks in abundance and were often absent from the water column for long periods. Spatially, North West Bay and the Channel had a higher representation of typically marine species, including Calanus australis and Labidocera cervi, while truly estuarine species, such as the copepod Gladioferens pectinatus, were more important in the Huon Estuary.

2004年11月至2005年10月期间，研究人员对塔斯马尼亚州德安特卡斯特海峡、霍恩河口及西北湾全域的中浮游动物（Mesozooplankton）群落组成与结构展开了调查。该中浮游动物群落的组成具有近岸温带海洋生境的典型特征——夏季与秋季丰度较高，冬季与春季则较低。在所有季节及站点中，桡足类对总丰度的贡献最大；而枝角类与有尾类则在春季和夏季占比较高。这三大类群的粪球，以及磷虾与端足类的粪球，也对沉积物捕获器回收的物质贡献显著。底栖动物的暂时性浮游幼体丰度呈短期峰值，且常长时间从水体中消失。空间分布方面，西北湾与海峡区域典型海洋物种（包括Calanus australis及Labidocera cervi）的占比更高；而霍恩河口则以真正的河口物种（如桡足类Gladioferens pectinatus）更为重要。数据来源于IMAS元数据目录，访问链接为https://metadata.imas.utas.edu.au/geonetwork/srv/eng/metadata.show?uuid=b89e4a97-4ce5-455a-ae3a-a88415b50541，获取日期为2021年2月3日。
