Published information from the Western Indian Ocean (WIO) and new data from the South West Indian Ocean Ridge, are consolidated and combined to generate an updated biogeography of calanoid copepods. The WIO was divided into 75 5° grid squares, and a similarity

The Paracalanidae are ecologically-important marine planktonic copepods that occur in the epipelagic zone in temperate and tropical waters. They are often the dominant taxon – in terms of biomass and abundance – in continental shelf regions. As primary

The copepod community structure from the Northern and Central/southern upwelling regions off Chile was studied and compared. The derived community descriptors were species abundance (N), species richness (R) and the Shannon-Wiener diversity index (H′).
