[Synopsis] We found large numbers of the exotic millipede, Chamberlinius hualienensis, which is originally distributed in Hualien, Taiwan, from two areas in Wakayama Prefecture. Because there was no trace of a large amount of soil or plants brought into the study sites, and the millipede was univoltine, these populations suggested their invasion was not recent in Wakayama Prefecture. The density of the millipede was 9.5±8.1 ind./m2 in the forest in Tanabe City. Its density was lower than observed when outbreaks occurred in Kanagawa and Okinawa Prefectures (1/6- 1/54 times). Therefore, it was considered that there was no outbreak of millipede at this site at this time. This is the first report showing the possibility of the millipede has invaded in the Kinki region in Central Japan.

[Synopsis]Degradation of the Philippines’ coastal environment with economic growth is expected to negatively impact tidal flat inhabiting mollusks. But there are few studies investigating local changes in quantity and species composition of Philippine tidal flat mollusks. This study surveyed the quantity and species composition of tidal flat mollusks at several coastal sites and those being sold at the local markets of the Visayas, Philippines, compared the results between sites and against previous studies, and estimated current resource quantity and ecological status of the tidal flat habitat. The total volume of mollusks sold in Cebu –significantly, mollusks from mangrove and freshwater habitats have decreased as compared to 30 years past. No change in volume was found in Dumaguete, Negros Island. The results indicate decreasing population and species number of mollusks in the tidal flats of Cebu possibly caused by worsening coastal degradation due to widespread urbanization of the island. This study suggests implementation of mollusk resource management and prevention of further coastal environment disturbance and over-exploitation of coastal resources in the Visayas, Philippines.
