We conducted inquiry investigations in order to reveal the spread of introduced bird species in Japan. Forty-three exotic species are known to breed or are regarded as breeding. The Feral Pigeon (Columba livia), Chinese Bamboo Partridge (Bambusicola thoracica), Red-billed Leiothrix (Leiothrix lutea), Budgerigar (Melopsittacus undulatus) and Red Avadavat (Amandava amandava) are widely distributed. The Rose-ringed Parakeet (Psittacula krameri manillensis), Common Peafowl (Pavo cristatus), Light-vented Bulbul (Pycnonotus sinensis), Melodious Laughing Thrush (Garrulax canorus), Crested Myna (Acridotheres cristatellus) and Black-billed Magpie (Pica pica sericea) are locally common, though they have limited ranges. Sightings of other species were sporadic and regionally limited. Most of introduced birds in Japan are escaped caged birds. About two thirds are from tropical regions, and show diet generalism as omnivores, ...

Blooms of cyanobacteria are notorious symptoms of eutrophication in freshwaters all over the world, deteriorating water quality as well as the health of human and natural resources. The genus Microcystis is the most frequently found cyanobacterial bloom. The present project has been elucidated the following issues on Microcystis aeruginosa blooms in eutrophic lakes: dispersal of M. aeruginosa into various lakes, ecology and phylogeography of particular genotypes of M. aeruginosa, and the relationship between human activity and Microcystis bloom.
