Isotopic Discrimination in the Double-Crested Cormorant (Phalacrocorax auritus). [PDF]
PLoS ONE, 2015 The diet-tissue discrimination factor is the amount by which a consumer's tissue varies isotopically from its diet, and is therefore a key element in models that use stable isotopes to estimate diet composition.

Amino acid-specific isotopes reveal changing five-dimensional niche segregation in Pacific seabirds over 50 years [PDF]
Scientific ReportsHutchison’s niche theory suggests that coexisting competing species occupy non-overlapping hypervolumes, which are theoretical spaces encompassing more than three dimensions, within an n-dimensional space.

Hematology and serum chemistry of captive juvenile double-crested cormorants (Phalacrocorax auritus). [PDF]
Can Vet J, 1999 Hematologic and serum chemical values were obtained for double-crested cormorants (Phalacrocorax auritus) to improve clinical diagnosis of disease in this species. Blood samples were collected from 20 captive double-crested cormorants at 4 to 6 weeks of age. Hematocrit and leukocyte concentrations were determined in heparinized blood. Concentrations of

Capture and telemetry techniques for double-crested cormorants (Phalacrocorax auritus) [PDF]
Proceedings of the Vertebrate Pest Conference, 2000 Author(s): King, D. Tommy; Tobin, Mark E. | Abstract: Double-crested Cormorants (Phalacrocorax auritus) often roost in cypress oxbows and nest on islands making their capture for research studies difficult. In the southeastern United States we used a capture technique involving a boat equipped with flood lights, flushing the birds out of their roost ...

Diets of shags Phalacrocorax aristotelis and cormorants P. carbo in Norway and possible implications for gadoid stock recruitment [PDF]
, 1990 The diets of shags and cormorants were studied in Norway through analyses of regurgitated pellets. Although this method has many limitations, indications were that both species rely heavily on small gadoids (Gadidae) and sand eels (Ammodytidae) for food ...
