| organochlorine pesticide residues in animals of tasmania, australia-1975-77. | animals taken in tasmania including duck (anas superciliosa), eel (anguilla australis), english perch (perca fluviatilis), white-faced heron (ardea pacifica), brown trout (salmo trutta), european starling (strunus vulgaris), cat (felis cattus), cormorant (phalacrocorax sp.), mutton bird (puffinus tenuirostris), tasmanian devil (sarcophilus harrisii), rainbow trout (salmo gairdnerii), tasmanian raven (corvus mellori), tench (tinca tinca), and quail (coturnix sp.) were sampled for p,p'-dde, pp,p'- ... | 1979 | 537866 |
| 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 |
| Monitoring of wild birds for Newcastle disease virus in north Queensland, Australia. | Wild aquatic birds (WABs) are considered as reservoir hosts for Newcastle disease viruses (NDVs) and may act as vectors for transferring these viruses to poultry, causing outbreaks of disease. A 3-year epidemiological study was conducted on WABs of north Queensland from April 2007 to March 2010. Swab and fresh moist faecal samples of WABs were screened to detect Newcastle disease viral (NDV) RNA by one-step real time reverse transcriptase polymerase chain reaction (rRT-PCR) in multiplex primers, ... | 2012 | 21945812 |
| epidemiology of avian influenza in wild aquatic birds in a biosecurity hotspot, north queensland, australia. | migratory birds may introduce highly pathogenic h5n1 avian influenza from southeast asia into australia via north queensland, a key stopover along the east asian-australasian flyway, with severe consequences for trade and human health. a 3-year repeated cross sectional study on the epidemiology of avian influenza in australian nomadic wild aquatic birds was conducted in this potential biosecurity hotspot using molecular and serological techniques. avian influenza virus subtypes h6 and h9 were co ... | 2015 | 25481624 |
| proximate cues to phases of movement in a highly dispersive waterfowl, anas superciliosa. | waterfowl can exploit distant ephemeral wetlands in arid environments and provide valuable insights into the response of birds to rapid environmental change, and behavioural flexibility of avian movements. currently much of our understanding of behavioural flexibility of avian movement comes from studies of migration in seasonally predictable biomes in the northern hemisphere. we used gps transmitters to track 20 pacific black duck (anas superciliosa) in arid central australia. we exploited la n ... | 2015 | 26331024 |
| correspondence between urban bird roosts and the presence of aerosolised fungal pathogens. | habitat fragmentation in urban environments concentrates bird populations that have managed to adapt to these newly developed areas. consequently, the roosts of these birds are potentially creating environments conducive to fungal growth and dissemination. airborne fungi derived from these environments are relatively unstudied, as is the potential health risk arising from these fungi. this study documented the diversity of culturable airborne fungal propagules associated with forty urban bird ro ... | 2016 | 27177454 |
| metagenomic characterisation of avian parvoviruses and picornaviruses from australian wild ducks. | ducks can shed and disseminate viruses and thus play a role in cross-species transmission. in the current study, we detected and characterised various avian parvoviruses and picornaviruses from wild pacific black ducks, chestnut teals, grey teals and wood ducks sampled at multiple time points from a single location using metagenomics. we characterised 46 different avian parvoviruses belonging to three different genera dependoparvovirus, aveparvovirus and chaphamaparvovirus, and 11 different avia ... | 2020 | 32733035 |
| metagenomics detection and characterisation of viruses in faecal samples from australian wild birds. | we present an optimised metagenomics method for detection and characterisation of all virus types including single and double stranded dna/rna and enveloped and non-enveloped viruses. initial evaluation included both spiked and non-spiked bird faecal samples as well as non-spiked human faecal samples. from the non-spiked bird samples (australian muscovy duck and pacific black ducks) we detected 21 viruses, and we also present a summary of a few viruses detected in human faecal samples. we then p ... | 2018 | 29875375 |
| serologic evidence of exposure to highly pathogenic avian influenza h5 viruses in migratory shorebirds, australia. | highly pathogenic avian influenza (hpai) h5nx viruses of the goose/guangdong/96 lineage continue to cause outbreaks in poultry and wild birds globally. shorebirds, known reservoirs of avian influenza viruses, migrate from siberia to australia along the east-asian-australasian flyway. we examined whether migrating shorebirds spending nonbreeding seasons in australia were exposed to hpai h5 viruses. we compared those findings with those for a resident duck species. we screened >1,500 blood samples ... | 2019 | 31538564 |
| heavy rainfall triggers increased nocturnal flight in desert populations of the pacific black duck (anas superciliosa). | understanding of avian nocturnal flight comes mainly from northern hemisphere species in seasonal temperate ecosystems where nocturnal flight is often precisely timed and entrained by annual photoperiod. here we investigate patterns of nocturnal flight in waterbirds of australian desert ecosystems that fly considerable distances to find temporary water bodies formed from rainfall which is highly unpredictable seasonally and spatially, and when there is sufficient water, they then breed. how they ... | 2017 | 29242630 |
| 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 |
