| validation of spilornis cheela hoya taqman probes for potential gender identification of many accipitridae species. | the objective of this study was to test the hypothesis that genders of accipitridae species, with the same or similar sequences to our previously proposed spilornis cheela hoya (s. c. hoya) chromo-helicase-dna binding protein (chd)-w-specific and chd-zw-common taqman probes, can be successfully determined. eight species of accipitridae with known genders were collected. after pcr, ta cloning, sequencing, and alignment analyses, sequence length differences of griffiths p2/p8 pcr amplicons between ... | 2010 | 19959218 |
| sexual dimorphism in jaw muscles of the japanese sparrowhawk (accipiter gularis). | materials suitable for anatomical research of raptorial birds are rare. bird-eating raptors show distinct inter-sexual differences in body size and parental roles. the large females catch larger prey and prepare small morsels to feed their young using their hooked beaks. here, we investigated the architectural properties of different jaw muscles of the japanese sparrowhawk (accipiter gularis) and examined whether there is sexual dimorphism in their architectural design. the results showed that m ... | 2017 | 28891073 |
| fluorinated alkyl compounds including long chain carboxylic acids in wild bird livers from japan. | a wide range of fluorinated alkyl compounds (facs) has been reported in wildlife in various locations in the world. however, such information regarding japanese wildlife is rarely found. in the present study, we investigated the occurrence of 21 facs, including perfluorinated alkyl sulfonates (pfass), perfluorinated carboxylates (pfcas), and fluorotelomer acids, in the livers of 10 wild bird species from two regions in northern japan. to avoid interferences, facs were quantified by a recently de ... | 2011 | 21190717 |
| morphological and molecular characterization of avian trypanosomes in raptors from thailand. | from september 2012 to may 2018, blood samples from 364 raptors (mostly adults) were collected and screened for trypanosomes and haemosporidians by microscopic examination and nested polymerase chain reactions (pcr). trypanosoma spp. were identified in 15 birds from eight different species. light microscopy revealed 14 cases of infection with trypanosoma cf. corvi, including one each in black-shouldered kite (elanus caeruleus, n = 49), brahminy kite (haliastur indus, n = 50), and spotted owlet ( ... | 2019 | 31230161 |
| genetic structure in japanese and thai populations of the japanese sparrowhawk accipiter gularis. | the japanese sparrowhawk accipiter gularis is a small raptor that breeds in northeast asia. the species consists of the widespread and mostly migratory subspecies a. g. gularis that is common in east asia, including japan, and the resident and endangered subspecies a. g. iwasakii which inhabits the ryukyu and yaeyama islands in okinawa, southern japan. given the minimal knowledge about the migration of the species, in this study we sought to compare the genetic variation of the populations breed ... | 2020 | 32549537 |
