| dna barcodes of philippine accipitrids. | dna barcoding is a molecular method that rapidly identifies an individual to a known taxon or its closest relative based on a 650-bp fragment of the cytochrome c oxidase subunit i (coi). in this study, dna barcodes of members of the family accipitridae, including haliastur indus (brahminy kite), haliaeetus leucogaster (white-bellied sea eagle), ichthyophaga ichthyaetus (grey-headed fish eagle), spilornis holospilus (crested serpent-eagle), spizaetus philippensis (philippine hawk-eagle), and pith ... | 2011 | 21429130 |
| Non-invasive sex identification of the white-bellied sea eagle (Haliaeetus leucogaster) through genetic analysis of feathers. | The white-bellied sea eagle, Haliaeetus leucogaster, displays reversed sexual size dimorphism and is monomorphic for adult plumage coloration. Early attempts to identify sex in sexually monomorphic birds were based on morphological or chromosomal characters, but since avian W-specific DNA sequences were identified, PCR amplification has become commonly used for molecular sexing. We used a PCR test employing primers that amplify two homologous fragments of both the CHD-W gene, unique to fem ... | 2011 | 22009862 |
| metal and isotope analysis of bird feathers in a contaminated estuary reveals bioaccumulation, biomagnification, and potential toxic effects. | the derwent estuary, in south east tasmania, is highly contaminated with heavy metals, mainly due to past industrial pollution. this study sought to determine the extent of contamination, bioaccumulation, and biomagnification in the resident bird community and therefore to infer the potential for adverse effects in birds. thirteen metals were measured from breast feathers (n = 51 individuals) of eight sympatric species of aquatic bird. stable carbon (δ13c) and nitrogen (δ15n) isotopes were used ... | 2018 | 29730716 |
| the distribution of nesting white-bellied sea-eagle (haliaeetus leucogaster) in penang national park, malaysia: conservation and management issues. | taman negara pulau pinang (penang national park) is the only site on pulau pinang that supports a large population of the white-bellied sea-eagle (wbse) haliaeetus leucogaster; however, the nesting sites of wbses have not been widely studied. as information on the location of wbse nesting sites is very important for conservation works by local authorities, the objective of this study was to determine the distribution of nesting wbses in the coastal dipterocarp forest of penang national park. sur ... | 2013 | 24575248 |
