“…It has to be emphasized that most common copepod species found during the present study do not belong to temperate water species according to the proposed ecological classifications by some researchers (Takahashi and Hirakawa 2001). We suggest here in accordance with previous studies that copepods have been transported from the Kuroshio Current into southwest Taiwan through the Luzon Strait based on similarity analyses (Lo et al 2004;Hwang et al 2007). This intrusion has been evidenced by physical data before (Liu et al 2003).…”

“…This intrusion has been evidenced by physical data before (Liu et al 2003). The Kuroshio Current intrusion through the Luzon Strait into the northern South China Sea and southwest Taiwan may also in part explain why copepods show a very high diversity in adjacent waters of the intrusion areas (Hwang et al 2007).…”

“…Such copepods can provide suitable indicators for water mass movements such as the intrusion of Kuroshio Current waters that are otherwise characterized by different temperature and salinities (Hsieh et al 2004;Hsiao et al 2004;Hwang et al 2007;Hsiao et al 2011). It has to be emphasized that most common copepod species found during the present study do not belong to temperate water species according to the proposed ecological classifications by some researchers (Takahashi and Hirakawa 2001).…”

Background: It is controversial to what extent the intrusion of the Kuroshio Branch Current to the Luzon Strait and the South China Sea circulation can shape copepod assemblages around southern Taiwan. We tested the hypothesis that currents such as the Kuroshio Current bring marine zooplankton and copepods from subtropical and tropical waters to the south of Taiwan. We studied copepod assemblages from the Bashi Channel in the northeastern South China Sea at the coast of southwest Taiwan during early October 1996. Results: A total of 77 copepod species were identified from 34 genera that included calanoids, cyclopoids, harpacticoids, and poecilostomatoids. Several indicator species suggest that the study area is highly influenced by water masses from the northern South China Sea as well as from the Kuroshio Current. Acrocalanus gracilis (Paracalanidae, Calanoida) was most abundant (with a relative abundance (RA) of 22.07 and an occurrence rate (OR) of 100%), followed by Paracalanus aculeatus (Paracalanidae, Calanoida) and Oncaea venusta (Cyclopoida). The stations close to the Kuroshio Current showed a higher species diversity (H') and a higher species richness with 3.9 to 4.6 at moderate abundance, whereas station 11 showed lowest species diversity (H') with (2.1), accompanied by the far lowest species number (14) and abundance (880 ind./100 m 3 ).

Abstract:The Paracalanus parvus species complex is one of the most dominant and ecologically important copepod groups in the waters around Japan. However, the overall taxonomic classification of the species complex has not been sufficiently defined to date. In this study, both genetic and morphological analyses were performed on specimens of the P. parvus species complex collected along the O-line , a monitoring line located at 138°E, south of Japan. Among the individuals collected, P. nanus specimens were clearly distinguishable morphologically, whereas other specimens could be classified into three reproductively isolated species. These distinctions are based on genetic analyses of the mitochondrial cytochrome oxidase subunit I (mtCOI) and nuclear large subunit (nLSU) ribosomal RNA. By comparing the genetic and morphological data with findings from previous studies, these three species were identified as P. tropicus, P. indicus, and an as-yet undescribed species (Paracalanus sp. (NWP)). The latter possesses a humped forehead and was found to be a dominant species within the surveyed continental slope area. As a distinguishing characteristic, the humped forehead was not consistently useful as it was prominent in only about half of the individuals collected. Morphological discrimination between this species and P. indicus was only made possible by comparing the relative length of exopod segment 3 on swimming leg 4. Despite morphological similarities among member species, ecological studies on the P. parvus species complex conducted around Japan may mostly concern the undescribed species, Paracalanus sp. (NWP), considering that P. indicus was found only in warmer waters in this study.

“…The community structure of plankton is generally affected by the dynamics of water masses (Hwang et al 2000a(Hwang et al , 2007aTseng et al 2012b) and the effects of monsoons (Hwang et al 2004Dur et al 2007;Tseng et al 2008cTseng et al , 2011cDahms et al 2012). Li et al (2010) suggested that the SCS is the world's bestknown monsoonal climate zone.…”

Background: For the present study, we collected mesozooplankton in the upper layer (above 100 m in depth) of four stations in the northern South China Sea (SCS) to determine the influence of different water masses on their distribution and abundance from 27 September to 2 October 1999. Results: In total, 18 major zooplankton taxa were recovered from the samples. Calanoid copepods, Noctilucales, and chaetognaths were dominant and together comprised 65.90% of the overall zooplankton counts. Zooplankton densities ranged from 102.19 to 1,285.24 individuals per cubic meters (ind./m
