An Apparatus for Determining the Respiratory Volume of Large Aquatic Birds
Science, 1946The apparatus shown in Fig. 1 is designed to adapt the oxygen dilution method of clinical lung-volume determination to the measurement of the total respiratory volume of various aquatic birds. In this method, the respiratory gases of the subject are mixed, through a mouthpiece, with a known quantity of oxygen, and the lung volume is calculated by the ...

Influenza virus subtypes in aquatic birds of eastern Germany
Archives of Virology, 1994We report the findings of a 12-year surveillance study (1977-89) of avian influenza A viruses in eastern Germany. Viruses were isolated directly from feral ducks (n = 236) and other wild birds (n = 89); from domestic ducks (n = 735) living on a single farm; and from white Pekin ducks (n = 193) used as sentinels for populations of wild aquatic birds ...

A retrospective study of neuroschistosomiasis in aquatic birds
Veterinary PathologySchistosomatidae is a family of trematodes that generally have an indirect life cycle, with snails as intermediate hosts in avian schistosomiasis and aquatic birds as definitive hosts. Although multiple studies report avian schistosomes, there are only a few reports describing gross and histological lesions of neuroschistosomiasis ...

Anthropogenic debris and pathology in aquatic birds
2017Plastics in marine and freshwater environments area global environmental issue. Plastic ingestion is associated with a variety of deleterious health effects for wildlife, and is a focus of much international research and monitoring. However, little research has focused on the ramifications of plastic debris for freshwater organisms.
