“…La cantidad de plancton encontrada alrededor de isla de Pascua es bastante escasa y esto mismo se observó en los sifonóforos, que constituyeron el 3,4% del zooplancton total (Mujica, 1993). Al respecto, Vinogradov (1991) señala que las aguas del giro anticiclónico del Pacífico Sur corresponden a una de las mayores regiones oligotróficas de los océanos, donde los valores de biomasa son extremadamente bajos. Sin embargo, considerando que las muestras se obtuvieron en un muestreo exploratorio de la capa superficial (0-5 m), se determinó un alto número de especies en comparación con otros resultados obtenidos en el archipiélago de Juan Fernández (Palma, 1985), costa central (Palma, 1973(Palma, , 1994Palma y Rosales, 1995) de estudio y área geográfica mucho más extenso.…”

Esta mayor diversidad observada en isla de Pascua, concuerda con los altos valores estimados para este mismo grupo en aguas cálidas del Atlántico Norte (Pugh, 1974) y de Papua Nueva Guinea (Pagès et al, 1989), así como con las altas diversidades determinadas para los anfípodos hypéridos en las cercanías de isla de Pascua (Vinogradov, 1991).…”

Recibido 29 enero 1999; versión corregida 21 abril 1999; aceptado 22 abril 1999. RESUMEN.Se analizan los sifonóforos colectados en muestras planctónicas superficiales alrededor de isla de Pascua en mayo de 1992. Se identificó un total de 15 especies de sifonóforos calicóforos, todos ellos registrados por primera vez para esa región insular. La especie más abundante fue Chelophyes contorta (43%), con una densidad máxima de 135 ind./1000 m 3 , seguida de Bassia bassensis (23%). Las especies restantes fueron escasas y su abundancia relativa fue inferior al 10%. Palabras claves: sifonóforos, zooplancton, abundancia, isla de Pascua. Siphonophores (Cnidaria, Hydrozoa) from surface waters of Easter IslandABSTRACT. Planktonic siphonophores sampled out near Easter Island during May 1992 were studied. Samples were taken with Bongo nets towed horizontally during 10 minutes between 5 and 10 meters of depth. A total of 15 species were identified, all of them are first records for the region. The most abundant species was Chelophyes contorta (43%), with a maximum density of 135 ind./1000 m 3 , followed by Bassia bassensis (23%). Other species were scarce and their relative abundance was in all cases lower than 10%.

“…A group of species including Phronima atlantica, Phronimella elongata, Phrosina semilunata, and some species of Primno was proposed by Vinogradov (1999) (Vinogradov 1991), the Gulf of California (Siegel-Causey 1982) and the CC area off Baja California (Lavaniegos & Hereu 2009), suggest a different trend. In the study area and in other tropical Pacific regions, Hyperioides sibaginis and Lestrigonus bengalensis were the most abundant (Gasca & Franco-Gordo 2008, Zeidler 1984, Valencia & Giraldo 2009).…”

“…Hyperiid amphipods are a significant component of epi-and mesopelagic communities in the tropical ocean, where they are represented mainly by the Physocephalata group (Vinogradov 1991). Most hyperiid species have a wide distribution or are cosmopolitan, although true cosmopolitanism has been questioned by Shih (1986).…”

The species composition and abundance of the planktonic Hyperiidea and their relationship with environmental factors (depth, temperature, salinity, dissolved oxygen, turbidity and chlorophyll a concentration) were analyzed based on 4 seasonal investigations in the Beibu Gulf between 2006 and 2007. Hyperiids were represented by 82 species, 5 of which had not previously been recorded in the South China Sea. The hyperiid communities were dominated by Lestrigonus bengalensis year-round, Hyperioides sibaginis was dominant in spring, summer and autumn, and Tullbergella cuspidata became dominant in spring. Both species richness and the Shannon-Wiener diversity index increased from north to south, and from nearshore to offshore. Biodiversity was higher in some regions where the water mass was strongly influenced by the open sea or the lower salinity water off the northern sea shelf. Results of partial correlation analysis showed that species richness was positively related to depth at all times, and negatively related to temperature only in summer and winter. TWINSPAN classification indicated that the Hyperiidea community was divided into 2 groups in spring and winter (a widely distributed group and a pelagic warm-water group), and 3 groups in summer and autumn. A clear distinction between euryhaline and pelagic species can be discerned, based on different geographical distributions of water masses.
