A virus infecting the harmful bloon~ causing microalga Heterosjgma akashiwo (Raphidophyceae) was isolated from the coastal water of Nomi Bay, Japan, In July 1996. The isolate caused lysis in 2 strains of H. akashiwo tested and numerous virus-like particles (VLPs) appeared in the lysed algal culture, whereas virus multiplication was not detected in the healthy culture of H. akashiwo without its ...

The genus Trigonopterus Fauvel, 1862 is highly diverse in Melanesia. Only one species, Trigonopterusamphoralis Marshall, 1925 was so far recorded West of Wallace's Line (Eastern Sumatra). Based on focused field-work the fauna from Sundaland (Sumatra, Java, Bali, Palawan) and the Lesser Sunda Islands (Lombok, Sumbawa, Flores) is here revised. We redescribe Trigonopterusamphoralis Marshall and de...

We first reported here that the harmful alga Cochlodinium polykrikoides, which had been previously known as an autotrophic dinoflagellate, was a mixotrophic species. We investigated the kinds of prey species and the effects of the prey concentration on the growth and ingestion rates of C. polykrikoides when feeding on an unidentified cryptophyte species (Equivalent Spherical Diameter, ESD = 5.6...
