Abstract. Population growth of piscivorous species raises concerns when it could affect aquaculture activities. In this study, an increase of the Neotropic Cormorant (Phalacrocorax brasilianus) population in the Ecuadorian Andes was documented using census data from three high Andean lakes (Yahuarcocha, San Pablo and Yambo) for 2004–2010.

Studies on Neotropical Fauna and Environment, 2000
Seasonal parameters of infection by the nematode Contracaecum rudolphii in the Neotropic cormorant Phalacrocorax brasilianus (Phalacrocoracidae) and their relation with feeding and infection in fishes from River Valdivia, Chile, were determined. The prevalences of infection in birds were similar during seasons, whereas mean intensity and percentages of

Cardiovascular physiology of embryonic neotropic cormorants (Phalacrocorax brasilianus).
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2023Cardiovascular maturation in avian species has primarily been studied in precocial species of birds, with few studies conducted on altricial species, which make up the majority of avian species.

Breast feathers of Neotropic Cormorants (Phalacrocorax brasilianus) from two nesting colonies in Lake Livingston (LALIV) and Richland Creek, Texas, were collected during 2014 and were analyzed for metals and metalloids. Mean concentrations of Al, As, Cr, Cu, Fe, Pb, Sb, and Se were not significantly different in breast feathers of cormorants from the ...

Complete mitochondrial genome of the Neotropic cormorant (Phalacrocorax brasilianus)
Mitochondrial DNA Part A, 2017The complete sequence of the Neotropic cormorant (Phalacrocorax brasilianus) mitochondrial DNA was obtained by the shotgun sequencing approach. The mitogenome is 19 042 bp in length and includes 13 protein-coding genes, 2 ribosomal subunit genes, 22 transfer RNA genes, a control region and a duplicated region of 2418 bp.

Diet of Neotropic cormorant (Phalacrocorax brasilianus) in an estuarine environment
Marine Biology, 2007The diet of the Neotropic cormorant (Phalacrocorax brasilianus) was studied by analysing 289 regurgitated pellets collected from a roosting site at Lagoa dos Patos estuary, southern Brazil, between November 2001 and October 2002 (except April to June). In total, 5,584 remains of prey items from 20 food types were found.

Parasitology Research, 2011
Forty-seven specimens of Neotropical cormorants, Phalacrocorax brasilianus, from Lago Guaíba, Guaíba, State of Rio Grande do Sul, Brazil (30° 00' S, 51°15' W), were examined for helminth parasites between 1999 and 2003. Twenty species of helminth parasites were found: ten digeneans: Austrodiplostomum mordax, Austrodiplostomum compactum, Clinostomum sp.,

Stable isotope analysis has been extensively used to establish trophic relationships within avian communities of marine ecosystems. The Neotropic Cormorant (Phalacrocorax brasilianus) is a good representative of marine bird communities along the northern coasts of South America.

We investigated chick development and feeding rate in the neotropic cormorant, Phalacrocorax brasilianus, in a colony in Central Chile. The year of our study was characterized by relatively good foraging conditions. Brood sizes varied from two to five chicks, and hatching was asynchronous, with gaps of 0 to 6 days between the youngest and the oldest ...
