We found two species of oribatid mites from Babeldaob Island of Palau Republic, which is an island country located in the western Pacific Ocean. Eurhynchoribates brevisensillatus sp. nov. is proposed from mosses growing in the forest, and a diagnostic key to adults of all known species of Eurhynchoribates is provided. Another species, Basilobelba foliata Hammer, 1982 is reported for the first time from Palau, which was known previously from island of Bali, Indonesia. Following the descriptions and comparisons, we discuss aspects of the diversity, distribution and habitat ecology of species belonging to each genus.

We found two species of galumnid mites from Babeldaob Island of the Palau Republic, which is an island located in the western Pacific Ocean. In the present work, we describe Trichogalumna ekaterinae sp. nov., which is clearly different from other known species of Trichogalumna in the specific structure of sensillus, reduced number of notogastral porose areas, and smaller body size. A supplementary description of another species, Galumna flabellifera, which is recorded for the first time in Palau, is given. Furthermore, we discuss aspects of the distribution, diversity and habitat ecology of species belonging to these genera in the Oriental region.

We found four species of oribatid mites belonging to family Oppiidae from Babeldaob Island of Palau Republic, which is an island country located in the western Pacific Ocean. Two new species, Anomaloppia babeldaobensis sp. nov. and Oxyoppia palauensis sp. nov. are described from litter and soil in a secondary forest of Palau, and supplementary descriptions of two hitherto known species, Arcoppia corniculifera (Mahunka 1978) and Arcoppia hammerae Rodríguez & Subías, 1984 are provided, which are reported for the first time from the Oceania region. Following the descriptions and comparisons, aspects of the taxonomy, distribution and habitat ecology of studied species are discussed.

Abstract. Prochlorococcus, the smallest but most abundant marine primary producer, plays an important role in carbon cycling of the global ocean. As a phototroph, Prochlorococcus is thought to be confined to the euphotic zone, with commonly observed maximum depths of ~ 150–200 m, but here we show for the first time the substantial presence of Prochlorococcus populations in the dark ocean ("deep Prochlorococcus" hereafter). Intensive studies at the Luzon Strait in the western Pacific Ocean show that the deep Prochlorococcus populations are exported from the euphotic zone. Multiple physical processes including internal solitary waves could be responsible for the transportation. These findings reveal a novel mechanism for picoplankton carbon export other than the known mechanisms such as sinking of phytodetritus and aggregates or grazing-mediated transportation.

Sixteen deep-sea polyplacophoran species are reported in this article, fifteen of which were found for the first time in the waters of Taiwan. Two of these species, Leptochiton taiwanensis n. sp. and L. wui n. sp., are described as new to science. Several of these species are distributed near Japan and in other areas of the western Pacific Ocean. Eight of the reported species live and feed on sunken wood. A survey of the polyplacophorans of Taiwan has also been conducted. The updated list of chitons collected near Taiwan at all depths contains 34 species. Seventeen of these species are shallow-water and seventeen species are deep-water chitons.
