日本語の「ダロウ」には、推量の用法と確認要求の用法がある。一方、中国語の文末語気詞「吧(ba)」にも日本語の「ダロウ」と対応する用法がある。この論文では、対話にしか現れない日本語の確認要求の用法がどういう場合に中国語の「吧(ba)」と対応し、またどういう場合に対応しないのかを考察する

「ダロウ」と「吧(ba)」の確認要求用法の比較

The deep-sea squat lobster Kiwa tyleri is the dominant macroinvertebrate inhabiting hydrothermal vents on the northern and southern segments of the East Scotia Ridge in the Southern Ocean. Here, we describe the first zoeal stage of the species - which is morphologically advanced - and provide evidence for its lecithotrophy in development. This morphologically advanced stage at hatching suggests that dispersal potential during early ontogeny may be limited. Adults of Kiwa tyleri typically inhabit a warm-eurythermal, and spatially defined, temperature envelope of vent chimneys. In contrast, ovigerous females with late embryos are found away from these temperatures, off vent site. This implies that at least part of embryogenesis takes place away from the chemosynthetic environment. Larvae are released into the cold waters of the Southern Ocean that are known to pose physiological limits on the survival of reptant decapods. Larval lecithotrophy may aid long developmental periods under these conditions and facilitate development independent of pronounced seasonality in primary production. It remains uncertain, however, how population connectivity between distant vent sites may be achieved

Evidence for protracted and lecithotrophic larval development in the yeti crab Kiwa tyleri from hydrothermal vents of the East Scotia Ridge, Southern Ocean
