Factors restricting the range expansion of the invasive green anole Anolis carolinensis on Okinawa Island, Japan

The green anole Anolis carolinensis invaded the Ogasawara Islands in Japan, drove various native species to extinction, and its distribution expanded 14 years after initial establishment. A. carolinensis invaded Okinawa Island, but it has not expanded its distribution in more than 25 years, although its density is extremely high in the southern region. To determine whether A. carolinensis has t...

Two new species of Asellota (Crustacea, Isopoda) from coral reefs on Iriomote Island, Okinawa, Japan

Pleurocope iriomotensis sp. n. and Prethura tuberculata sp. n. are described from Iriomote Island, Ryukyu Archipelago, southern Japan. These are the first records of Pleurocope from the Pacific and of Prethura from the Asian Pacific coast. Pleurocope iriomotensis differs from its congeners in having lateral spine-like processes on pereonite 4 and coxal plates of pereonite 7. Prethura tuberculat...

Detection of Ehrlichia platys DNA in brown dog ticks (Rhipicephalus sanguineus) in Okinawa Island, Japan.

Thirty-two Rhipicephalus sanguineus females collected from eight free-roaming dogs in Okinawa Island, Japan, were examined for ehrlichial DNA by 16S rRNA-based PCR and subsequent sequencing. Partial sequences of Ehrlichia platys 16S rRNA (678 to 679 bp) were detected in three ticks (9.4%) from two dogs. This is the first report of detection of E. platys in Japan, and also the first report of de...

Mosquito biodiversity patterns around urban environments in South-central okinawa island, Japan.

Okinawa is the largest, most urbanized, and densely populated island in the Ryukyus Archipelago, where mosquito species diversity has been thoroughly studied. However, the south-central Okinawa mosquito fauna has been relatively poorly studied. Here, we present results from a mosquito faunal survey in urban environments of Nishihara city, south-central Okinawa. Mosquitoes were sampled biweekly,...
