An Apparatus for Determining the Respiratory Volume of Large Aquatic Birds

Science, 1946
The 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 ...

Importance of the National Petroleum Reserve–Alaska for Aquatic Birds

Conservation Biology, 2013
Abstract We used data from aerial surveys (1992–2010) of >100,000 km 2 and ground surveys (1998–2004) of >150 km 2 to estimate the density and abundance of birds on the North Slope of Alaska (U.S.A.).

Avian schistosomes in French aquatic birds: a molecular approach

Journal of Helminthology, 2009
AbstractThe prevalence of human cercarial dermatitis (HCD) caused by bird schistosomes appears to be increasing in France, in light of the impact of tourism combined with high densities of wild aquatic hosts in freshwater areas. The present work expands our knowledge of schistosome systematics by including samples of bird schistosomes collected from ...

A retrospective study of neuroschistosomiasis in aquatic birds

Veterinary Pathology
Schistosomatidae 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

2017
Plastics 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.

Assessing the toxic threat of selenium to fish and aquatic birds

Environmental Monitoring and Assessment, 1996
A procedure is given for evaluating the toxic threat of selenium to fish and wildlife. Toxic threat is expressed as hazard, and is based on the potential for food-chain bioaccumulation and reproductive impairment in fish and aquatic birds, which are the most sensitive biological responses for estimating ecosystem-level impacts of selenium contamination.
