Parasitology Research, 2018
Hemosporidian parasites rarely infect aquatic birds. Few studies have been conducted in South America identifying some lineages of the genera Plasmodium, Leucocytozoon, and Haemoproteus, but none has been done in the Neotropic cormorant (Phalacrocorax brasilianus).

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 ...

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.

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.

Cardiovascular physiology of embryonic neotropic cormorants (Phalacrocorax brasilianus)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative PhysiologyCardiovascular 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. In the precocial species of birds studied to date, cardiovascular regulation is derived primarily from an adrenergic receptor stimulation that is present from ...

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 ...
