AbstractThe porcellanid species Raphidopus ciliatus Stimpson, 1858, and Raphidopus indicus Henderson, 1893, are reported from Singapore and Peninsular Malaysia respectively for the first time. This is the first record of the genus Raphidopus Stimpson, 1858, from Southeast Asia. A third species of Raphidopus, R. johnsoni sp. nov., is also described from Singapore mangroves. Pseudoporcellanella manoliensis Sankarankutty, 1961, a rare and unusual taxon, is also recorded from Peninsular Malaysia, the South China Sea and the Gulf of Thailand for the first time. Detailed redescriptions and extensive figures are provided for all four species, and their taxonomy and ecology discussed.

Ceriops Tagal

Demographic history and dispersal ability are significant factors in determining the genetic composition of a population. In this study, we examined the phylogeographic patterns of Ceriops tagal from the Hainan Island and the Gulf of Thailand in the South China Sea, where there are abundant mangrove species. Nucleotide variations in two chloroplast DNA spacers were compared with trace Ceriops propagule dispersal routes and demographic history. An analysis of Templeton, Crandall and Sing’s (TCS) parsimonious networks and population demographics suggests that the Ceriops population gradually expanded from the northern parts of the South China Sea to the south-western populations in the Gulf of Thailand. Such phylogeographic inferences reflect a postglacial southward shift in the mangrove genetic diversity centre and a connection between the demographic dynamics and the coastal range expansion caused by the sea-level rise in the Pleistocene. Therefore, the phylogeographic pattern and historical demography of mangrove species were affected by glaciations during the Pleistocene such as temperate biota.

Resonant Period

Abstract. The Gulf of Thailand is dominated by diurnal tides, which indicates that the resonant period of the gulf is potentially close to one day. However, when applied to the gulf, the classic quarter wavelength resonant theory fails to give a diurnal resonant period. In this study, we first perform a series of numerical experiments showing that the resonant period of the gulf is approximately one day and that the resonance of the South China Sea body has a critical impact on the resonance of the gulf. In contrast, the resonance of the Gulf of Thailand has little influence on the resonance of the South China Sea body. An idealised two-channel model that can reasonably explain the dynamics of the tidal resonance in the Gulf of Thailand is then established in this study.

Abstract. The Gulf of Thailand is dominated by diurnal tides, which might be taken to indicate that the resonant frequency of the gulf is close to one cycle per day. However, when applied to the gulf, the classic quarter-wavelength resonance theory fails to yield a diurnal resonant frequency. In this study, we first perform a series of numerical experiments showing that the gulf has a strong response near one cycle per day and that the resonance of the South China Sea main area has a critical impact on the resonance of the gulf. In contrast, the Gulf of Thailand has little influence on the resonance of the South China Sea main area. An idealized two-channel model that can reasonably explain the dynamics of the resonance affecting the Gulf of Thailand is then established in this study. We find that the resonant frequency around one cycle per day in the main area of the South China Sea can be explained with the quarter-wavelength resonance theory, and the large-amplitude response at this frequency in the Gulf of Thailand is basically a passive response of the gulf to the increased amplitude of the wave in the southern portion of the main area of the South China Sea.

The stenopodidean shrimp Odontozona spongicola (Alcock & Anderson, 1899) collected by the South Java Deep-Sea Biodiversity Expedition 2018 (SJADES 2018) is a new record from Indonesia. The specimen of O. spongicola recently listed from the South China Sea is also formally reported here in. The characteristcs and coloration of this rare species are described and illustrated.
