| prevalence of blood parasites in japanese wild birds. | the prevalence of blood parasites was investigated in 701 japanese wild birds for 13 years from january, 1988 to march, 2001. most of the injured or sick birds were caught in the suburbs of kobe city, hyogo prefecture and brought to the zoo for clinical care. among all the birds examined, 10.6% were infected with hematozoa belonging to three genera as plasmodium (1.7% of the samples), haemoproteus (5.1% of the samples) and leucocytozoon (4.6% of the samples), and two birds (0.29% of the samples) ... | 2002 | 12399602 |
| phylogenetic comparison of leucocytozoon spp. from wild birds of japan. | eight species of japanese birds were found to be infected with leucocytozoon species using microscopic analysis. we used pcr and sequence analysis of the mitochondrial cytochrome b gene (cyt b) to compare the genetic background among these detected protozoa species. in 20 individuals of 22 samples, a single amplified band was detected from 6 of 8 bird species; 9 japanese rock ptarmigans (lagopus mutus japonicus), 4 large-billed crows (corvus macrorhynchos), 2 carrion crows (c. corone), 2 scops o ... | 2007 | 17283401 |
| interspecific and annual variation in pre-dispersal seed predation by a granivorous bird in two east asian hackberries, celtis biondii and celtis sinensis. | pre-dispersal seed predation by granivorous birds has potential to limit fruit removal and subsequent seed dispersal by legitimate avian seed dispersers in bird-dispersed plants, especially when the birds form flocks. we monitored pre-dispersal seed predation by the japanese grosbeak, eophona personata, of two bird-dispersed hackberry species (cannabaceae), celtis biondii (four trees) and celtis sinensis (10 trees), for 3 years (2005, 2007 and 2008) in a fragmented forest in temperate japan. thr ... | 2012 | 22136589 |
