| hematology, plasma chemistry, serology, and chlamydophila status of the waved albatross (phoebastria irrorata) on the galapagos islands. | venipuncture was performed on 50 adult, free-ranging waved albatrosses (phoebastria irrorata) on española, galapagos islands, ecuador, to establish hematologic and plasma biochemistry reference ranges and to determine the prevalence of exposure to important domestic avian pathogens. weights and plasma creatine phosphokinase activities differed significantly between males and females. serum was tested for evidence of exposure to avian influenza, avian paramyxoviruses 1, 2, and 3, avian cholera, a ... | 2003 | 14582791 |
| avian pox discovered in the critically endangered waved albatross (phoebastria irrorata) from the galápagos islands, ecuador. | the waved albatross (phoebastria irrorata) is a critically endangered seabird in a rapidly shrinking population in the galápagos islands, ecuador. the introduction of novel pathogens and parasites poses a threat to population persistence. monitoring disease prevalence and guarding against the spread of such agents in endemic taxa are conservation priorities for the galápagos, where recent increases in the prevalence of avian pox may have contributed to population declines and range contractions ... | 2017 | 28715294 |
| gastrointestinal parasites in the waved albatross (phoebastria irrorata) of galápagos. | using a fecal flotation technique, we detected three genera of endoparasites in the critically endangered waved albatross (phoebastria irrorata) of galápagos. these genera were contracaecum, tetrabothrius, and cardiocephaloides. juvenile albatrosses were more likely to be infected than adults, but we found no effect of sex or mass on infection probability. | 2015 | 25919468 |
| the environmental-data automated track annotation (env-data) system: linking animal tracks with environmental data. | the movement of animals is strongly influenced by external factors in their surrounding environment such as weather, habitat types, and human land use. with advances in positioning and sensor technologies, it is now possible to capture animal locations at high spatial and temporal granularities. likewise, scientists have an increasing access to large volumes of environmental data. environmental data are heterogeneous in source and format, and are usually obtained at different spatiotemporal scal ... | 2013 | 25709817 |
| waved albatrosses can navigate with strong magnets attached to their head. | the foraging excursions of waved albatrosses phoebastria irrorata during incubation are ideally suited for navigational studies because they navigate between their galápagos breeding site and one specific foraging site in the upwelling zone of peru along highly predictable, straight-line routes. we used satellite telemetry to follow free-flying albatrosses after manipulating magnetic orientation cues by attaching magnets to strategic places on the birds' heads. all experimental, sham-manipulated ... | 2003 | 14555754 |
| extra-pair paternity in waved albatrosses. | we estimated the rate of extra-pair fertilizations (epfs) in waved albatrosses (phoebastria irrorata) on isla española, galápagos, ecuador, using multilocus minisatellite dna fingerprinting. waved albatrosses are socially monogamous, long-lived seabirds whose main population is on española. aggressive extra-pair copulation (epc) attempts have been observed in the breeding colony during the days preceding egg-laying. our genetic analyses of 16 families (single chicks and their attending parents) ... | 2000 | 10972780 |
