Hierarchical Analysis of Zooplankton Assemblages over Semidiel Pattern in the Lagoon of Kavaratti Atoll, Lakshadweep Archipelago, India

並列摘要


A hierarchical analysis of data concerning the zooplankton assemblages over a semidiel pattern were presented in the inside waters of Kavaratti lagoon. Gastropod larvae dominated in all time intervals throughout the study. The dendrogram matrix clearly indicated the community interrelation ships expressed by this univalve molluscan group over semidiel pattern towards other groups of zooplanktons aggregated in the collections. Copepod varieties form a single separate cluster and showed its presence as an opportunistic invader to the lagoon ecosystem. In the lagoon the zooplankton assemblages and community structure seem to be clearly more balanced over the diel variation, which is clearly reflected in the cluster tree plotted.
