Traditionally, many small-sized copepod species are considered to be widespread, bipolar or cosmopolitan. However, these large-scale distribution patterns need to be re-examined in view of increasing evidence of cryptic and pseudo-cryptic speciation in

Abundance and productivity of smaller copepods such as the cyclopoid Oithona spp. have been substantially underestimated in most studies, primarily due to large mesh sizes employed during zooplankton tows. Several studies demonstrate that the assemblage

Temporal changes in abundance and distribution patterns of cyclopoid copepods belonging to the genus Oithona were analyzed from a 3 yr survey in the South China Sea comprising 9 sampling cruises, during spring, summer, and autumn of 2000-2002. Plankton
