| counts of selected duck species at corner inlet, victoria: changes in relation to local and distant meteorological variations. | numbers of four duck species present within a study area in a tidal embayment (corner inlet, south-eastern australia) were obtained between 1977 and 2002. the species involved were chestnut (anas castanea) and grey (a. gracilis) teal, pacific black duck (a. superciliosa) and australian shelduck (tadorna tadornoides) and counts are compared with local and distant meteorological data. chestnut and grey teal were most, and australian shelduck least, abundant. there was considerable monthly and annu ... | 2010 | 19937455 |
| detection of a reassortant h9n2 avian influenza virus with intercontinental gene segments in a resident australian chestnut teal. | the present study reports the genetic characterization of a low-pathogenicity h9n2 avian influenza virus, initially from a pool and subsequently from individual faecal samples collected from chestnut teals (anas castanea) in southeastern australia. phylogenetic analyses of six full gene segments and two partial gene segments obtained from next-generation sequencing showed that this avian influenza virus, a/chestnut teal/australia/ct08.18/12952/2018 (h9n2), was a typical, low-pathogenicity, euras ... | 2020 | 31940999 |
| metagenomic characterisation of additional and novel avian viruses from australian wild ducks. | birds, notably wild ducks, are reservoirs of pathogenic and zoonotic viruses such as influenza viruses and coronaviruses. in the current study, we used metagenomics to detect and characterise avian dna and rna viruses from wild pacific black ducks, chestnut teals and grey teals collected at different time points from a single location. we characterised a likely new species of duck aviadenovirus and a novel duck gyrovirus. we also report what, to the best of our knowledge, is the first finding of ... | 2020 | 33335272 |
