Molecular markers for population genetic analyses in the family Psittacidae (Psittaciformes, Aves)
The selection of molecular markers for population studies is an important tool for biodiversity conservation. The family Psittacidae contains many endangered and vulnerable species and we tested three kinds of molecular markers for their potential use in population studies of five psitacid species: 43 hyacinth macaws (Anodorhynchus hyacinthinus), 42 blue-and-yellow macaws (Ara ararauna), 23 red...

Chromosomal Diversity and Karyotype Evolution in South American Macaws (Psittaciformes, Psittacidae)
Most species of macaws, which represent the largest species of Neotropical Psittacidae, characterized by their long tails and exuberant colours, are endangered, mainly because of hunting, illegal trade and habitat destruction. Long tailed species seem to represent a monophyletic group within Psittacidae, supported by cytogenetic data. Hence, these species show karyotypes with predominance of bi...
