structure and variation of the anseriformes mitochondrial dna control region.the control region is the major non-coding segment of animal mitochondrial dna. to infer the structure and variation of anseriformes mitochondrial dna control region, the control region sequences of 52 species were analyzed. the length of the control region sequences ranged from 968 bp (chenonetta jubata) to 1335 bp (anseranas semipalmata) and can be separated into three domains. there is a deletion of 100-130 bp in anatinae, compared to other groups of anserinae. the average genetic distances a ...201625329267
adapting to the unpredictable: reproductive biology of vertebrates in the australian wet-dry tropics.in the wet-dry tropics of northern australia, temperatures are high and stable year-round but monsoonal rainfall is highly seasonal and variable both annually and spatially. many features of reproduction in vertebrates of this region may be adaptations to dealing with this unpredictable variation in precipitation, notably by (i) using direct proximate (rainfall-affected) cues to synchronize the timing and extent of breeding with rainfall events, (ii) placing the eggs or offspring in conditions w ...200817638689
four new avian mitochondrial genomes help get to basic evolutionary questions in the late cretaceous.good phylogenetic trees are required to test hypotheses about evolutionary processes. we report four new avian mitochondrial genomes, which together with an improved method of phylogenetic analysis for vertebrate mt genomes give results for three questions in avian evolution. the new mt genomes are: magpie goose (anseranas semipalmata), an owl (morepork, ninox novaeseelandiae); a basal passerine (rifleman, or new zealand wren, acanthisitta chloris); and a parrot (kakapo or owl-parrot, strigops h ...200414739240
disseminated toxoplasmosis in magpie geese (anseranas semipalmata) with large numbers of tissue cysts in livers.fatal disseminated toxoplasma gondii infection was diagnosed in 2 captive magpie geese (anseranas semipalmata) from a zoo in texas. both geese died suddenly, without apparent clinical signs. lesions associated with t. gondii tachyzoites were seen in lungs, pancreas, liver, adrenals, bursa of fabricius, spleen, brain, and kidneys. toxoplasmic pneumonia and hepatitis were considered to be the primary cause of death. an unusual feature was the presence of numerous tissue cysts in hepatocytes of bot ...200111227896
[primary structure of alpha and beta chains from the major hemoglobin component of the magpie goose (anseranas semipalmata, anatidae)].the amino acid sequence of the alpha and beta chains from the major hemoglobin component (hba) of australian magpie goose (anseranas semipalmata) is given. the minor component with the alpha d chains was detected, but only found in low concentrations. by homologous comparison, greylag goose hemoglobin (anser anser) and australian magpie goose alpha chains differ by 13 amino acids or 17 nucleotide (4 two point mutations) exchanges, beta chains by 6 exchanges. seven alpha 1 beta 1 contacts are mod ...19836840695
sequences of sixteen phosphoserine peptides from ovalbumins of eight species.phosphoserine peptides have been isolated by a diagonal electrophoresis method from proteolytic digests of ovalbumins from hen, grouse, turkey, golden pheasant, magpie goose, chinese goose, aylesbury duck and fulvous whistling duck. the amino acid sequences of these peptides have been determined. there are two sites of phosphorylation in each ovalbumin, which are located in two different regions of the ovalbumin molecule. amino acid replacements are more frequent in the site 1 sequences than in ...19816783411

more taxa, more characters: the hoatzin problem is still unresolved.the apparently rapid and ancient diversification of many avian orders complicates the resolution of their relationships using molecular data. recent studies based on complete mitochondrial dna (mtdna) sequences or shorter lengths of nuclear sequence have helped corroborate the basic structure of the avian tree (e.g., a basal split between paleognathae and neognathae) but have made relatively little progress in resolving relationships among the many orders within neoaves. we explored the potentia ...200312777516
avitourism and australian important bird and biodiversity areas.formal protected areas will not provide adequate protection to conserve all biodiversity, and are not always designated using systematic or strategic criteria. using a systematic process, the important bird and biodiversity area (iba) network was designed to highlight areas of conservation significance for birds (i.e. iba trigger species), and more recently general biodiversity. land use activities that take place in ibas are diverse, including consumptive and non-consumptive activities. avitour ...201526701779

biogeographic models of gene flow in two waterfowl of the australo-papuan tropics.there are many large, easy-to-observe anseriform birds (ducks, geese, and swans) in northern australia and new guinea and they often gather in large numbers. yet, the structure of their populations and their regional movements are poorly understood. lack of understanding of population structure limits our capacity to understand source-sink dynamics relevant to their conservation or assess risks associated with avian-borne pathogens, in particular, avian influenza for which waterfowl are the main ...201223170215
